Kev lig kev cai, tib neeg feem ntau siv bakelite, hluav taws xob, nylon, yas, roj hmab, ceramic thiab lwm yam ntaub ntawv insulating raws li matrix cov khoom siv hluav taws xob sib sau ua ke hu ua cov khoom siv hluav taws xob bakelite.Nws yog qhov tseem ceeb ntawm cov khoom siv hluav taws xob sib txuas ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, lossis qhov hloov pauv uas qhib thiab kaw lub voj voog.Cov khoom siv Bakelite feem ntau suav nrog lub teeb tuav, lub thawv xaim, hloov, ntsaws, lub qhov (socket) thiab lwm yam.Kev tsim tawm ntawm hom noBakelite pan handles yog qhov loj, kev siv ntau yam, yog siv dav hauv tsev neeg cov khoom siv hluav taws xob hauv tsev.
Keeb kwm ntawm cov khoom siv bakelite
Qee cov ntoo feem ntau tsim cov resins, tab sis amber yog cov pob txha ntawm cov resins, thiab shellac, tab sis kuj suav hais tias yog cov resins, yog ib qho nyiaj tso cia los ntawm cov kab kab ntawm cov ntoo.Shellac xim, ua los ntawm shellac, yog Ameslikas tsuas yog siv raws li ib tug preservative rau ntoo, tab sis nrog lub invention ntawm hluav taws xob motors los ua thawj insulating xim siv.Nyob rau hauv lub xyoo pua 20th, txawm li cas los xij, hluav taws xob tsis tuaj yeem ntsib los ntawm cov khoom ntuj tsim, ua rau muaj kev tshawb nrhiav tshiab thiab pheej yig dua.
Nyob rau hauv lub xyoo pua 19th, German chemist A. Bayer thawj zaug pom tias phenol thiab formaldehyde tuaj yeem tsim cov pob liab liab los yog rab phom thaum cua sov hauv cov kua qaub, tab sis qhov kev sim tau nres vim lawv tsis tuaj yeem ua kom huv los ntawm cov txheej txheem classical.
Nyob rau hauv lub xyoo pua 20th,Baekelandthiab nws cov neeg pabcuam kuj tau ua tiav qhov kev tshawb fawb, pib nrog kev cia siab ntawm kev ua cov xim insulating es tsis txhob siv cov khoom siv ntuj tsim.Tom qab peb xyoos ntawm kev ua haujlwm nyuaj, thaum kawg ntawm lub caij ntuj sov xyoo 1907, lawv tsis tsuas yog ua cov xim pleev xim, tab sis kuj ua cov khoom siv hluavtaws tiag tiag, Bakelite.Nws yog lub npe hu ua bakelite.
Muaj ib hnub hauv qab no, German chemist Beyer, ua kev sim nrog phenol thiab formaldehyde nyob rau hauv ib lub khob, pom tias muaj cov nplaum nplaum tau tsim sab hauv.
Tom qab xyoo kev sim, nws hloov tawm tias yam uas tau siv los ua "kev ntxhov siab" tam sim no dhau "plees".Phenolic tsis pom dej, cua sov tsis deformation, muaj qee yam kev siv zog.Nws yog ib qho yooj yim rau txheej txheem, tab sis kuj muaj cov rwb thaiv tsev zoo, uas yog tsuas yog tshwm sim rau kev lag luam hluav taws xob, Dab tsi yog qhov loj invention.Yog li ntawd, nws yog dav siv nyob rau hauv zus tau tej cov hluav taws xob nres, lub teeb keyboards, lub teeb tuav, 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 nws lipan handles,lauj kaub tuav.Peb muaj ntau hom cookware tuav ua los ntawm Bakelite.
