Kev lig kev cai, tib neeg feem ntau siv bakelite, yas, roj hmab, ceramic, ceramic, ceramic, yas, ceramic thiab lwm yam khoom siv hluav taws xob ua ke xa mus ua cov khoom siv hluav taws xob hauv hluav taws xob. Nws yog qhov Infispensable hluav taws xob txuas nruab nrab ntawm cov khoom siv thiab cov khoom siv fais fab, lossis hloov pauv uas qhib thiab kaw Circuit Court. Bakelite cov khoom siv feem ntau yog suav nrog teeb lub teeb, hlau lub thawv, hloov, ntsaws, ntsaws, (ntswj thiab lwm yam. Kev tsim khoom ntawm hom noBakelite lauj kaub leeg yog loj, kev siv ntau qhov ntau, yog qhov feem ntau dav siv hauv tsev neeg ntawm cov khoom siv hluav taws xob hauv tsev.
Lub hauv paus chiv keeb ntawm bakelite khoom
Lub zais cia ntawm qee cov ntoo feem ntau ua cov resins, tab sis amber yog fossil ntawm cov resins, thiab sheetac, yog kuj zais cia zais cia ntawm plhaub ntawm cov ntoo. Shellac xim, ua los ntawm shellac, yog Ameslikas siv tsuas yog siv tshuaj rau ntoo, tab sis nrog kev tsim hluav taws xob rau thawj insulating pleev xim siv. Nyob rau hauv lub xyoo pua 20, txawm li cas los xij, hluav taws xob tsis tuaj yeem ntsib los ntawm cov khoom ntuj tau ntev, ua rau nrhiav kev tshawb nrhiav tshiab thiab pheej yig dua.
Nyob rau hauv lub xyoo pua puv 19, German Chemanist A. Bayer thawj zaug phenol thiab formaldehyde tuaj yeem nres vim tias lawv tsis tuaj yeem ua kom huv los ntawm cov qauv classical.
Hauv 20 caug xyoo,NpakelandThiab nws cov kev pab kuj tau tshawb nrhiav cov kev tshawb fawb, thaum pib nrog kev cia siab ntawm kev tso cai pleev xim hloov cov khoom siv ntuj. Tom qab peb xyoos ntawm kev ua haujlwm nyuaj, thaum kawg nyob rau lub caij ntuj sov xyoo 1907, lawv tsis yog ua cov pleev xim av, tab sis kuj tau ua cov khoom siv hluavtaws tiag, bakelite. Nws lub npe hu ua Bakelite.
Muaj ib hnub nyob rau hauv cov hauv qab no, German Chemanist Beyer, ua kev sim nrog phenol thiab formaldehyde nyob rau hauv ib tug flask thiab pom tias cov khoom nplaum tau tsim sab hauv.
Tom qab cov kev sim xyoo, nws hloov tawm tias dab tsi siv los ua "kev thab plaub" yog tam sim no dhau "txaus siab". Phenolic tsis pom dej, kub tsis deformation, muaj ib qho kev siv zog. Nws yog ib qho yooj yim rau cov txheej txheem, tab sis kuj muaj rwb thaiv tsev zoo, uas yog nyuam qhuav tawm ntawm kev lag luam hluav taws xob, yog dab tsi loj tsim tau. Yog li ntawd, nws yog dav siv nyob rau hauv kev tsim cov hluav taws xob brakes, lub tshuab nqus vaj tsev, xov tooj thiab lwm yam khoom siv hluav taws xob, uas nws tau txais lub npe bakelite. Txawm li cas los xij, peb xav qhia nws yog siv hauv kev lag luam Cookware, ua rau nws lilauj kaub leeg,Lot TesCov. Peb muaj ntau yam ntawm cov cookware daws tau los ntawm bakelite.
