Ruitai Chav Ua Noj Riam: Koj qhov Premier Qhov Chaw rau Kev Cai Chav Ua Noj Riam Teeb los ntawm Tuam Tshoj
Kuv ntseeg hais tias nyob rau hauv kev xav ntawm ntau tus phooj ywg, ceramics, ib qho nyuaj thiab nkig, ib txwm siv los ua cov thawv, tableware, vuas, decorations thiab lwm yam khoom. Kuv tsis paub tias koj puas tau nkag siab tias ceramics kuj tuaj yeem ua rau riam? siv nws. ceramic riam.
Rau cov tsoos hlau riam, txawm hais tias nws tuaj yeem ua tau raws li feem ntau ntawm cov kev xav tau txiav hauv tsev neeg lub neej, tseem muaj ntau yam tsis txaus.
Piv txwv li, cov riam hlau yog ib qho yooj yim rau xeb thiab hnav tsis zoo, tom qab lub sijhawm ntev, lawv yooj yim rau xeb thiab ua blunt, uas yog qhov tsis yooj yim rau ntau zaus. Nws yog nyob rau hauv cov xwm txheej no uas cov riam ceramic tau los ua.
Cov khoom siv hauv cov riam ceramics tsis yog ceramics raug rho tawm haujlwm los ntawm cov av ntuj uas muaj nyob hauv peb lub neej, tab sis cov niaj hnub high-tech tshwj xeeb ceramics uas yog cov khoom siv hluavtaws.
Raws li thaum ntxov xyoo 1912, qee lub tebchaws nyob sab Europe thiab Asmeskas tau siv alumina ua raw khoom los tsim alumina ceramic riam, tab sis vim nws qhov kev ua haujlwm qis, nws tsis tau lees paub los ntawm lub zej zog. Nws tsis yog txog 50 xyoo tom qab uas tib neeg tau tsim cov khoom siv sib xyaw alumina, lub zog thiab tawv ntawm cov riam uas ua los ntawm cov khoom no tau zoo heev, thiab cov riam ceramic tau maj mam nkag mus rau tib neeg lub zeem muag txij thaum ntawd los. Thaum xyoo 1980s, silicon oxide ceramic knives tau tawm los, cov khoom siv riam phom ceramic no yog ze heev rau cov khoom siv niaj hnub ceramic riam, thiab kev muag khoom ntawm cov riam ceramic hauv cov teb chaws tsim tau pib nce tsis tu ncua.
Nrog rau kev txhim kho txuas ntxiv ntawm cov cuab yeej siv hluavtaws, ntau thiab ntau cov khoom siv hluavtaws tau siv los ua cov riam ceramic. Cov riam niaj hnub no nyob rau hauv kev ua lag luam siv zirconia raws li cov khoom siv raw, thiab siv zirconia hmoov nrog molecular loj ntawm nanometers ci ntawm qhov kub ntawm ntau tshaj 2,000 degrees, thiab siv lub siab ntawm ntau tshaj 300 tons rau pwm. Ua tau. Muaj peev xwm tsim qhov khoob ntawm zirconia riam. Cov riam tsis muaj ces yog cov av nplaum los ntawm pob zeb diamond los ua ib rab riam ceramic.
Kev ua haujlwm ntawm zirconia ceramic riam yog qhov tsis sib xws los ntawm cov tsoos dawb ceramic riam, cov khoom siv zirconia tsis tsuas yog txhim kho lub zog, hardness, toughness thiab lwm yam, tab sis kuj muaj qhov zoo ntawm corrosion kuj, hnav tsis kam thiab kub tsis kam. Cov txiaj ntsig zoo no nthuav dav dav ntawm kev siv cov zirconia ceramic riam, tsis tsuas yog tuaj yeem txiav thiab ua cov ntaub ntawv hardness raws li cov kev xav tau sib txawv, tab sis kuj tuaj yeem ua kev txiav ceev ceev, thiab txawm tias txuas mus ntxiv ntawm qhov kub siab tshaj 1,000 degrees. yog ib yam dab tsi uas tsoos ceramic riam ua tsis tau. Tsis tas li ntawd, zirconia tseem hu ua "zircon gemstone" vim nws cov tsos zoo nkauj thiab muaj txiaj ntsig, thiab nws tuaj yeem piav qhia tau tias yog "noble riam".
