tham txog chav ua noj riam

Cov riam chav ua noj no yuav tsum suav tias yog cov cuab yeej tseem ceeb tshaj plaws hauv chav ua noj, qhov tseeb, nws yuav tsum yog cov cuab yeej qub tshaj plaws rau tib neeg, thiab tej zaum tseem yuav laus dua tib neeg lawv tus kheej: Qee cov kws tshawb fawb hauv Tebchaws Meskas tau qhia ib qho orangutan ua pob zeb. riam, yog li nws tuaj yeem kwv yees kwv yees tias nyob rau hauv Cov poj koob yawm txwv ntawm tib neeg tej zaum yuav tau kawm ua pob zeb riam ua ntej lawv hloov mus rau "tib neeg". Muaj ntau cov lus hais txog chav ua noj riam, ntawm cov uas tau nthuav dav tshaj plaws yog cov kws ua zaub mov Suav tsuas yog xav tau ib rab riam hauv chav ua noj kom kov yeej lub ntiaj teb, thaum cov kws ua zaub mov sab hnub poob xav tau ntau rab riam hauv chav ua noj los ua cov tais diav yooj yim tshaj plaws. Qhov tseeb, qhov no tsis yog qhov tseeb, txawm hais tias muaj tseeb tsuas yog ib rab riam hauv chav ua noj ntawm ntau tsev neeg Suav, rau cov kws ua zaub mov Suav saum toj kawg nkaus, yuav tsum muaj ntau hom riam yog tias lawv xav ua zaub mov Suav zoo, qhov yooj yim tshaj yog. chopping ribs.Koj tsis tuaj yeem siv tib rab riam li cov nqaij shredded (qhov qub yog qhov ruaj khov dua thiab lub kaum sab xis ntawm cov hniav yuav tsum loj dua, thaum lub tom kawg yuav tsum sharper thiab lub kaum sab xis ntawm cov hniav yuav tsum me dua), thiab nws yog tsis yooj yim sua. mus carve "Yim Immortals Hla Hiav Txwv" rau ntawm cov txiv hmab txiv ntoo rind nrog ib rab riam..

Yog hais tias koj tsis muaj lub tswv yim intuitive, koj tuaj yeem saib Ang Lee zaj yeeb yaj kiab "Food and Drink Man and Woman". Lub protagonist hauv nws yog tus kws ua zaub mov ntawm Grand Hotel hauv Taipei. Nws xav tau ntau lub txee los tso saib ntau hom chav ua noj. riam hauv nws chav ua noj. Tau kawg, zoo li txhua yam cuab yeej, riam chav ua noj no kuj muaj txoj cai "nees nkaum yim", tsis hais cov zaub mov Suav lossis cov zaub mov Western, 80% ntawm cov tais diav tuaj yeem ua tiav nrog ib rab riam, tab sis yog tias koj xav ua 20% ntxiv. ntawm cov tais diav, koj xav tau ntau ntau Ntau hom riam yuav ua. Lwm qhov laj thawj rau cov lus no yuav yog tias txhua tus neeg ua rau suav nrog chav ua noj hauv lub sijhawm ntawm cov khoom siv tsis txaus hauv kev nco nrog chav ua noj ntawm chav ua si hauv Western movies thiab TV.

Nws tsis yog qhov xav tsis thoob tias txij li hnub nyoog ntawm cov ntaub ntawv sau tseg, kev ua noj ua haus tau ua tsis tau zoo. Yog lawm, tsis muaj dab tsi yuav tsum tau them nyiaj rau hauv chav ua noj ntawm cov neeg pluag, thiab cov neeg nplua nuj yuav tsis siv nyiaj hauv chav ua noj. Lub ntsiab lus no kuj ceeb tias zoo ib yam ntawm Sab Hnub Tuaj thiab Sab Hnub Poob, tsis muaj chav ua noj hauv lub tsev qub nyob rau sab hnub poob, chav ua noj tsuas yog ib lub tsev nyob deb ntawm lub tsev loj.

Tom qab lub kiv puag ncig ntawm kev lag luam, nrog kev nce siab ntawm kev ua haujlwm, tus nqi ntawm kev ua haujlwm nyob rau sab hnub poob tau nce siab, thiab cov neeg nruab nrab, txawm tias cov poj niam hauv nruab nrab hauv nruab nrab yuav tsum ua noj los ntawm lawv tus kheej. lub impetus mus rau pem hauv ntej.Lub chav ua noj riam ntawm nto moo Western hom yog cov khoom ntawm no sib. Rau chav ua noj hauv tsev, ua ntej ntawm tag nrho cov nqaij nyoos thiab siav yuav tsum tau muab cais tawm los ntawm qhov kev pom no, Suav chav ua noj yog qhov xav tau ntau dua, vim tias cov neeg sab hnub poob tsis tshua txiav cov nqaij hauv lawv chav ua noj. los ntawm cov khw muag khoom noj khoom haus lossis cov nqaij, lub khw txiav cov nqaij ntim, tshem tawm cov ntim thiab muab pov ncaj qha rau hauv lub lauj kaub, tsis zoo li suav ua noj, feem ntau yuav tsum tau txiav cov nqaij los yog txiav. Tsis tas li ntawd, riam uas tau txiav cov dos thiab qhiav yuav tseem muaj cov ntxhiab tsw qab txawm tias koj ntxuav nws li cas, yog tias koj siv riam xws li txiav txiv lws suav los yog txiv lws suav, nws yooj yim rau nqa cov ntxhiab, yog li rab riam tshwj xeeb yog siv rau cov txiv hmab txiv ntoo. kev ua kuj tseem ceeb heev. ntawm.

Cov riam hauv peb chav ua noj yog npaj raws li txoj cai no: ib qho rau txiav nqaij, ib qho rau txiav zaub, thiab ib qho rau txiav txiv hmab txiv ntoo. Tsuav koj siv riam, muaj teeb meem kev nyab xeeb, qhov no yog qhov tseeb rau txhua tus neeg los ntawm cov neeg tshiab uas tuaj hauv chav ua noj rau cov kws ua zaub mov nto moo: hauv cov khoom noj "Iron Chef", ntau tus kws ua zaub mov koom nrog txiav lawv tus kheej ntiv tes hauv ib qho. nrawm. Hais txog qhov teeb meem no, ib lo lus hais tias "Lub riam no yog qhov zoo tiag tiag, tab sis nws yog qhov ntse heev, thiab nws yog qhov txaus ntshai dhau los txiav ntawm koj txhais tes!".

Qhov tseeb, ntawm qhov tsis sib xws, rab riam npub yog qhov txaus ntshai tshaj plaws, thaum siv riam, koj siv zog ntau dua thiab muaj peev xwm tswj tau ntau dua, yog tias koj plam, koj yuav luag ua rau koj tus kheej raug mob. Ob peb hnub dhau los, kuv pom ib txoj kev tshawb fawb uas tau teev cov zaub " phom sij" tshaj plaws hauv chav ua noj, thiab taub dag yog thawj. Yog vim li cas yog tias taub dag muaj tawv tawv thiab tuab nqaij, uas ua rau nws yooj yim kom tsis txhob sib npaug thaum txiav.

Txawm hais tias ua noj thiab hais lus paj huam, pleev xim, ua si piano thiab ua si chess yog ob yam sib txawv, lawv ob leeg yuav tsum muaj tus cwj pwm zoo, thaum koj ua siab ntev, koj yuav ua rau koj ob txhais tes, tshwj xeeb tshaj yog thaum koj pom cov kws ua zaub mov nto moo ya riam thiab txiav. zaub hauv TV, thaum koj xyaum nws, koj tsuas yog ib nrab kauj ruam deb ntawm "ntshav splattered ntawm lub rooj txiav". Nyob rau lub sijhawm no, tsis txhob cia siab tias yuav muaj rab riam ntse ntse, LG feem ntau hais ib kab lus zoo heev (qhov tseeb, nws tau hnov ​​​​los ntawm lwm qhov): "Lub riam blunt yog ib txwm ceev thaum txiav tes." Los ntawm lwm qhov kev pom, lub qhov txhab tsim los ntawm rab riam ntse ntse muaj qhov sib tsoo loj dua cov khoom siv microscopically thiab nws nyuaj rau rov zoo dua, thaum lub qhov txhab tsim los ntawm rab riam ntse yog ntau huv si thiab zoo dua.

Yog li, tsis muaj teeb meem dab tsi, tsis txhob siv cov riam hauv chav ua noj. Jamie Oliver qhov kev pab cuam tau muab cov lus qhia zoo txog cov teeb meem kev nyab xeeb: ua ntej, muab cov ntaub ntub dej me ntsis rau hauv lub rooj txiav plaub hau kom tsis txhob muaj kev sib tsoo ntawm cov chopping board thaum lub sij hawm txiav, thiab qhov thib ob, thaum txiav zaub, nco ntsoov ua ntej mus rau theem ntawm cov tais diav, Piv txwv li, thaum txiav cov qos yaj ywm, koj tuaj yeem ua ntej txiav lub dav hlau tawm ntawm cov qos yaj ywm, thiab tom qab ntawd siv lub dav hlau no los kho cov qos yaj ywm ntawm lub rooj txiav kom tsis txhob muaj kev sib tsoo thaum lub sij hawm txiav. Thib peb, lees paub koj tus kheej theem, txiav ncaj ncees thiab maj mam (qhov no tau sau los ntawm LG rau nws, haha, nyob rau hauv ntau ntawm nws cov kev pab cuam, nws sim kom tsis txhob qhia tawm nws cov txuj ci riam, txhob txwm ua kom qeeb kom tsis txhob yuam kev rau cov neeg tuaj saib).

Thaum thawj tus ape qub tau kawm los khob flint los ua thawj "chopper", tsuas muaj ib hom ntawv hauv ntiaj teb. Tam sim no ntau lab xyoo dhau los, cov neeg dawb huv lub siab thaum ub tau hloov zuj zus mus rau hauv tib neeg nrog ntau cov kab mob uas muaj xim zoo nkauj, thiab "Cai Riam Sect" tau tshwm sim ntau ceg. Ntawm lawv, muaj peb yam uas muaj feem cuam tshuam: Western-style kws ua zaub mov riam, Japanese Santoku riam, thiab tau kawg peb paub zoo Suav chav ua noj riam riam.

Cov kws ua zaub mov sab hnub poob no tseem hu ua Fab Kis tus kws ua zaub mov riam, Txawm hais tias German craftsmen thawj zaug paub txog cov riam no, German zaub mov tsis zoo, thiab nws tau nrov los ntawm lub caij nplooj ntoos hlav cua ntawm Fabkis cuisine. Western-style kws ua zaub mov cov riam muaj ib tug ntev, nqaim hniav nrog ib tug tuab rov qab thiab ib tug sharply nkhaus ntug. Qhov no muaj feem xyuam rau txoj kev siv cov riam hauv chav ua noj Western-style, cov kws ua zaub mov siv lub hau ntawm rab riam ua ib qho fulcrum, thiab cov hniav swings nce thiab nqis rau ntawm chopping board zoo li guillotine rau chop zaub mov.

Ib tug kws ua zaub mov noj riam muaj qhov ntse heev nrog lub kaum sab xis me me nyob ze ntawm lub taub thiab tsim nyog rau kev txiav npluav, thaum lub ntug nyob ze ntawm tus kov muaj lub kaum sab xis loj dua thiab tsim nyog rau kev txiav cov pob txha ntses lossis lwm yam me ntsis nyuaj. tus kws ua zaub mov riam: Tham txog riam phom (1) Cov koob nrov ntawm Japanese Santoku riam yog sib cais los ntawm kev txhawb nqa loj ntawm Western chav ua noj riam riam. Lub Santoku Riam hu ua "Santoku Baoding" hauv Nyij Pooj, thiab "Baoding" txhais tau tias riam chav ua noj.

Thaum xub thawj siab ib muag, Santoku riam zoo ib yam li Western-style kws ua zaub mov riam, tab sis qhov tseeb muaj qhov sib txawv loj. Ua ntej tshaj plaws, cov hniav ntawm Santoku riam yog qhov ncaj, yog li qhov nce thiab nqis txav yog txoj hauv kev tseem ceeb ntawm kev siv, tsis zoo li "swinging" riam txoj kev ntawm Western-style kws ua zaub mov riam. Qhov thib ob, cov hniav yog nyias nyias, uas yog feem ntau haum rau txiav ntses thiab nqaij, nws tsis zoo li ntau yam zoo li tus kws ua zaub mov riam.

Santoku Riam: Tham txog riam phom (1) Txhua leej txhua tus paub txog cov tsoos suav square chav ua noj riam, yog li tsis tas yuav tham tsis muaj tseeb. Cov riam hauv chav ua noj feem ntau siv hauv cov tsev neeg Suav yog txhua qhov sib npaug sib npaug rau sab hnub poob-style kws ua zaub mov riam, ntxiv rau ua kom tiav cov txheej txheem txiav cov khoom xyaw, nws tseem tuaj yeem yooj yim hloov cov khoom xyaw txiav mus rau lub lauj kaub. ntawm thawj ob hom chav ua noj riam. ntawm. Tau kawg, tseem muaj ntau hom riam hauv chav ua noj hauv Suav teb, piv txwv li, qee qhov yog tuab thiab tsim nyog rau kev txiav cov pob txha ntawm cov nqaij qaib thiab cov tsiaj nyeg, thiab qee qhov yog nyias thiab nyias thiab zoo dua rau kev txiav npluav. Txawm li cas los xij, cov tsos ntawm cov hom no. riam tsis txawv heev, ntau tus neeg xav tias tsuas muaj ib hom riam hauv Suav teb xwb, tab sis tsis yog.

Cia peb tham txog cov khoom siv ntawm riam chav ua noj. Cov riam hauv chav ua noj hauv kev ua lag luam tsis muaj dab tsi ntau tshaj li peb cov ntaub ntawv, carbon steel, stainless hlau thiab ceramics. Tau kawg, muaj qee cov ntaub ntawv ruaj khov dua, xws li cov titanium ntshiab lossis titanium alloy, uas tau hais tias muaj zog corrosion kuj, thiab sib dua thiab hloov tau ntau dua li cov riam hlau, tab sis cov no tsis yog cov khoom siv feem ntau, yog li kuv yuav tsis. tham txog lawv ntawm no.

Cov riam hauv chav ua noj thaum ntxov tau ua los ntawm cov hlau. Txawm hais tias cov hlau ntshiab muaj qhov zoo tiv thaiv corrosion, nws qhov hardness tsis siab. Tom qab ntxiv cov pa roj carbon monoxide los ua ib homogeneous hlau-carbon alloy, nws dhau los ua hlau (tau kawg, cov txheej txheem tiag tiag tsis yooj yim li nws tau hais. Yog li ntawd, yog tias cov ntsiab lus carbon siab dhau, nws dhau los ua hlau, thiab tsuas yog cov hlau-carbon alloys uas muaj cov ntsiab lus ntawm 0.2% thiab 2.1% hu ua steel). tsawg kawg yog tsib txhiab xyoo dhau los, tab sis Nws tsuas yog nyob rau hauv ob txhiab xyoo dhau los uas cov cuab yeej hlau tuaj yeem tsim tau ruaj khov. Suav proverbs feem ntau hais tias "steel yog tsim los ntawm ib puas refinements", "zoo steel yog siv rau ntawm cov hniav", thiab lwm yam. Nws yuav pom tau hais tias high-zoo steel yuav tsum yog ib tug muaj txiaj ntsig zoo nyob rau hauv ancient sij hawm.

Muaj ntau qhov tsis meej tom qab ob lo lus pov thawj no. Qhov no "smelting rau hauv steel" tiag tiag yog hais txog cov txheej txheem ntawm forging thiab forging nyob rau hauv Tuam Tshoj thaum ub los tsim cov hlau zoo: cov kws ua hlau ua kom sov lub qhov khoob thiab pheej rov ua dua thiab folded nws, kom cov pa roj carbon nyob rau hauv nws tau sib npaug, thiab hardness thiab lub zog ntawm cov khoom tau zoo heev.. Thiab "cov hlau zoo yog siv rau ntawm cov hniav" hais tias cov kws ua hlau yuav tsum tau siv cov cuab yeej sib xyaw ua cov riam thaum cov ntaub ntawv tsis tshua muaj: sib txuas cov hlau zoo thiab lwm cov ntaub ntawv tsis zoo los ntawm kev sib tsoo. high-quality steel yog siv los ua cov hniav, thiab lwm yam ntaub ntawv tsim cov hniav.

Qhov tsis zoo ntawm cov hlau tsis zoo nyob rau lub sijhawm qub thiab tsis paub tseeb hauv kev tsim cov hlau tau ntxiv ntau qhov tsis meej rau qhov kev lag luam no, thiab kuj tau nthuav tawm ntau cov dab neeg hauv Suav teb, muaj cov lus dab neeg zoo xws li "Moxie", thiab hauv Suav teb. Nyob rau sab hnub poob, muaj "Damascus steel" lus dab neeg, txhua yam txuj ci tseem ceeb, xws li rab ntaj ua los ntawm Damascus hlau tuaj yeem yooj yim txiav tawm lub phom phom, cov plaub hau poob ntawm cov hniav yuav tawg ntawm nws tus kheej, thiab lwm yam. Cov lus dab neeg no tau cuam tshuam rau pej xeem txog tam sim no, Txawm hais tias cov hlau tsim los ntawm cov thev naus laus zis niaj hnub tau dhau los ntev dhau los ntawm Damascus steel, tib neeg tseem ntseeg tias tseem muaj cov khawv koob khawv koob zais tom qab cov qauv zoo nkauj. Txhawm rau kom haum rau qhov kev xav ntawm cov pej xeem, cov tuam txhab tsim cov riam hauv chav ua noj tau mob hnyav los tsim cov qauv ntawm Damascus steel nrog kev lag luam niaj hnub. Tam sim no koj tsis tas yuav mus rau Syria hauv Middle East, koj tuaj yeem mus rau qhov ze " IKEA” mus yuav Damascus chav ua noj riam thiab txaus siab. Tshawb xyuas cov kev xav thaum ub ntawm koj tus kheej.

Hauv qab no yog ib daim duab ntawm lub xyoo pua 18th Damascus steel riam: Tham txog rab riam chav ua noj (2) Cov ntsiab lus carbon muaj qhov txiav txim siab ntawm cov khoom ntawm cov hlau, qhov siab dua cov ntsiab lus ntawm cov pa roj carbon monoxide, qhov muaj peev xwm ua tau zoo dua hardness, tab sis lub toughness ntawm cov khoom kuj yuav raug txo. Cov hlau uas muaj cov ntsiab lus carbon ntawm 0.3-0.59% yog hu ua nruab nrab-carbon steel, uas muaj qhov sib npaug toughness thiab hardness, feem ntau yog siv los ua cov khoom siv kho tshuab uas hnyav heev, feem ntau siv los ua cov springs thiab nws cov high- lub zog steel hlau thiab lwm yam. Cov hlau uas muaj ntau tshaj li 1% carbon yog hu ua ultra-high carbon steel, uas tuaj yeem ua tiav siab hardness los ntawm kev kho cua sov, tab sis tsis zoo toughness.

Cov riam hauv chav ua noj ua los ntawm cov pa roj carbon siab lossis ultra-high carbon steel tuaj yeem ncav cuag hardness siab heev, thiab nws yooj yim rau sharpen cov hniav. Ntau cov riam Japanese yog ua los ntawm cov ntaub ntawv zoo sib xws, uas muaj feem xyuam rau kev txiav npluav uas feem ntau yuav tsum tau ua hauv Japanese cuisine. Tau kawg, cov pa roj carbon steel nws tus kheej kuj muaj qhov tsis muaj zog txaus.

Yog li ntawd, riam ua los ntawm cov khoom no yuav tsum tau ntxuav thiab qhuav tom qab siv. Cov riam uas ua los ntawm cov hlau tsis muaj hlau yog cov sib xyaw ua ke, ntau cov riam hauv chav ua noj pheej yig yog ua los ntawm cov pa roj carbon tsawg, cov hlau tsis tshua muaj carbon steel nws tus kheej pheej yig thiab yooj yim rau kev ua. Txawm li cas los xij, riam ua los ntawm cov hlau tsis tshua muaj hlau tsis yooj yim rau cov hniav, thiab cov hniav yog qhov nyuaj rau kev tswj xyuas, thiab nws yuav npub sai sai nrog kev siv.

Cov kws tshawb fawb tau ua haujlwm ntev ntev los txhim kho cov qauv ntawm cov hlau kom nws cov corrosion kuj. Nyob rau hauv lub xyoo pua 19th, tib neeg pom tias nws yuav yog ib lub tswv yim zoo los ntxiv chromium rau hlau. Tus txheej txheem yog tias cov ntaub ntawv chromium chromium cov pob tshab thiab cov kab mob oxide, uas tuaj yeem tiv thaiv cov hlau substrate los ntawm kev ua pa thiab noo noo hauv huab cua.

Yog tias txheej txheej ntawm zaj duab xis no raug rhuav tshem, cov hlau tshiab chromium yuav tsim tib zaj duab xis tiv thaiv dua sai sai tom qab raug huab cua, uas tiv thaiv tag nrho cov hlau tsis txhob xeb. Kev tiv thaiv corrosion ntawm stainless hlau yog ncaj qha ntsig txog cov ntsiab lus chromium, yog li tsuas yog cov ntsiab lus chromium tshaj 11% hu ua stainless hlau. Vim yog tus nqi siab ntawm cov hlau chromium, cov neeg tau txais txiaj ntsig los ntawm txhua qhov chaw ntawm lub neej sim txiav cov fab thiab cov khoom siv, thiab lub tswv yim zoo nkauj ntawm "stainless hlau" tau yug los hauv peb thaj av.

Txawm hais tias cov hlau tsis muaj steel hlau uas tsim nyog rau lub npe muaj qhov sib txawv ntawm kev tiv thaiv corrosion, yog li thaum muas stainless hlau chav ua noj riam thiab cov tais diav, xyuam xim tshwj xeeb rau cov khoom muaj pes tsawg leeg. Cov lus 18/10, 18/8 lossis 18/0 feem ntau yog cim rau ntawm stainless hlau tableware, uas yog hais txog feem pua ​​​​ntawm chromium thiab npib tsib xee cov ntsiab lus hauv cov khoom (qhov no yog qhov ua tau zoo ntawm qib stainless hlau tsis tu ncua, thiab peb cov ntaub ntawv kwv yees. Raws li tam sim no 316, 304 thiab 2 series stainless hlau). Nickel hauv stainless hlau yog qhov tsim nyog rau kev txhim kho cov khoom siv kho tshuab, thiab tib lub sij hawm muaj kev pab cuam ntawm corrosion kuj.

Txawm li cas los xij, npib tsib xee hlau tsis pheej yig, yog li qee cov tuam txhab siv cov hlau manganese es tsis txhob, qhov no yog lub hauv paus ua rau "stainous stainless hlau" xwm txheej tshwm sim los ntawm qee lub tuam txhab tsim khoom hauv tsev ib zaug dhau los. Feem ntau hais lus, txhua yam tshwm sim los ntawm cov nyiaj. 18/10 (uas yog, 316 stainless hlau) yog cov khoom siv zoo rau kev ua cov tais diav, riam, diav rawg thiab lauj kaub, tab sis nws yog ib qho nyuaj rau siv rau riam hauv chav ua noj, vim tias cov ntsiab lus carbon hauv nws tsuas yog 0.08%, thiab nws tsis tuaj yeem siv. tau txais los ntawm kev kho cua sov, siab hardness. Cov tuam txhab lag luam niaj hnub ntawm cov riam hauv chav ua noj siv qee cov qauv stainless hlau uas muaj cov pa roj carbon ntau, piv txwv li, cov khoom siv stainless hlau siv hauv WüSTHOF cov khoom muaj 0.5% carbon, uas yog ze rau cov ntsiab lus ntawm cov roj carbon siab.

Tau kawg, qee qhov chaw tsim khoom siv 440 series stainless hlau, cov ntsiab lus ntawm cov pa roj carbon monoxide yog siab li 0.6% mus rau 1.20%, uas belongs rau qib siab carbon steel thiab ultra-high carbon steel. Txawm li cas los xij, tsis muaj txiaj ntsig ntawm ob qho kawg, txhua yam muaj qhov zoo thiab qhov tsis zoo, cov pa roj carbon hauv cov hlau muaj qhov cuam tshuam rau kev tiv thaiv corrosion ntawm chromium, thaum cov ntsiab lus chromium tseem tsis hloov pauv, cov ntsiab lus carbon ntau dua, qhov ua rau corrosion kuj. . Rau cov cuab yeej xws li cov riam hauv chav ua noj uas yuav tsum tau ua nrog ntsev thiab kua qaub-puag txhua hnub, qhov ntse thiab corrosion kuj yog qhov tseeb ntawm cov khoom uas tsis tuaj yeem tsis quav ntsej. Cov tuam ntxhab sib txawv yuav muaj kev nkag siab sib txawv, tab sis cov neeg siv khoom yuav tsum xaiv raws li lawv tus kheej xav tau thiab nyiam. .

Cia peb tham txog cov khoom siv ceramic. Zirconium dioxide, hmoov dawb, tam sim no siv los ua cov riam hauv chav ua noj. Cov chaw tsim khoom muab cov hmoov no tso rau hauv cov cuab yeej sib tsoo ntawm chav ua noj riam tsis pub dawb, siv lub siab ntawm 120 cua thiab ci rau hauv ib puag ncig ntawm 1500 degrees, thiab cov hmoov no tau sintered rau hauv cov khoom ntom ntom.

Mohs hardness ntawm zirconia ceramics yog siab li 8.5, uas yog ntau tshaj li ntawm 6-6.5 ntawm hardened steel, yog li nws tsuas yog polished nrog ib tug pob zeb diamond sib tsoo log. tawv hniav. Vim hais tias ntawm nws cov hardness tsis tshua muaj siab, ceramic chav ua noj riam tsis tshua hnav nyob rau hauv ib txwm siv, thiab lawv cov tshuaj muaj zog ruaj khov, yog li lawv tsis ntshai ntawm kev tawm tsam ntawm acid, alkali thiab ntsev uas muaj nyob rau hauv chav ua noj. Tej zaum koj yuav xav tias tus thawj coj kev ua yeeb yam uas yog tus thawj coj hauv chav ua noj riam hauv ntiaj teb thaum kawg tau yug los, tab sis qhov no tsis yog li ntawd.

Piv nrog rau cov riam chav ua noj steel, cov riam ceramic yog cov tawv tawv heev, lawv yooj yim tawg thaum raug rau sab nraud quab yuam, thiab lawv kuj ua rau tawg thaum hniav txiav cov khoom tawv. Dab tsi yog qhov phem tshaj yog vim qhov hardness siab dhau lawm, tsis muaj txoj hauv kev los txhuam nws los ntawm cov txheej txheem ib txwm ua, thaum lub qhov tshwm sim, rab riam yuav luag tsis muaj txiaj ntsig. Raws li tau hais dhau los, muaj "28 txoj cai" thaum siv cov riam hauv chav ua noj. Txawm hais tias nws siv hauv tsev lossis los ntawm tus kws ua zaub mov, yeej ib txwm muaj ib hom riam uas siv ntau zaus (muaj ntau hom riam uas tsis nquag. siv). Haum rau Western ua noj.

Rau cov riam ceramic, vim nws cov tawv tawv thiab nkig, nws yog qhov tsis muaj peev xwm ua lub luag haujlwm ntawm lub hauv paus chav ua noj riam feem ntau siv, tab sis yog tias nws tshwj xeeb yog siv rau kev txiav cov txiv hmab txiv ntoo thiab zaub, nws tseem muaj cov txiaj ntsig zoo..
