Ib txwm muaj, tib neeg feem ntau siv bakelite, hluav taws xob, nylon, yas, roj hmab, ceramic thiab lwm yam khoom siv rwb thaiv tsev ua cov khoom siv hluav taws xob matrix, hu ua bakelite electrical appliances. Nws yog qhov tseem ceeb tshaj plaws ntawm cov khoom siv hluav taws xob thiab lub zog fais fab, lossis lub qhov hloov uas qhib thiab kaw lub voj voog. Cov khoom siv bakelite feem ntau suav nrog lub teeb tuav, lub thawv hlau, qhov hloov, ntsaws, qhov (socket) thiab lwm yam. Kev tsim cov khoom noCov tes tuav ntawm Bakelite yog loj, kev siv ntau yam, yog qhov siv dav tshaj plaws hauv tsev neeg ntawm cov khoom siv hluav taws xob hauv tsev neeg.
Keeb kwm ntawm cov khoom siv bakelite
Cov kua qaub ntawm qee cov ntoo feem ntau tsim cov resins, tab sis amber yog cov pob zeb ntawm cov resins, thiab shellac, txawm hais tias kuj suav tias yog cov resins, yog qhov tso nyiaj los ntawm cov kab shellac ntawm cov ntoo. Xim Shellac, ua los ntawm shellac, thawj zaug tsuas yog siv ua cov tshuaj tiv thaiv rau ntoo, tab sis nrog kev tsim cov cav hluav taws xob tau dhau los ua thawj xim rwb thaiv tsev siv. Txawm li cas los xij, nyob rau hauv lub xyoo pua 20th, kev siv hluav taws xob tsis tuaj yeem ua tiav los ntawm cov khoom ntuj, ua rau muaj kev tshawb nrhiav rau lwm txoj hauv kev tshiab thiab pheej yig dua.
Nyob rau hauv lub xyoo pua 19th, tus kws tshuaj German A. Bayer thawj zaug pom tias phenol thiab formaldehyde tuaj yeem ua rau lub pob xim av liab lossis gunk sai sai thaum cua sov hauv qab cov xwm txheej acidic, tab sis qhov kev sim tau raug tso tseg vim tias lawv tsis tuaj yeem ntxuav los ntawm cov txheej txheem qub.
Nyob rau hauv lub xyoo pua 20th,Baekelandthiab nws cov neeg pab kuj tau ua qhov kev tshawb fawb, thaum xub thawj nrog kev cia siab tias yuav ua cov xim rwb thaiv tsev es tsis yog cov resins ntuj. Tom qab peb xyoos ntawm kev ua haujlwm hnyav, thaum kawg lub caij ntuj sov xyoo 1907, lawv tsis yog tsuas yog ua cov xim rwb thaiv tsev xwb, tab sis kuj ua cov khoom siv yas tiag tiag, Bakelite. Nws hu ua bakelite.
Muaj ib hnub tom qab ntawd, tus kws tshuaj German Beyer, ua kev sim nrog phenol thiab formaldehyde hauv lub raj mis, pom tias muaj cov khoom nplaum tau tsim sab hauv.
Tom qab ntau xyoo sim ua, nws hloov tawm tias yam uas yav tas los "ua rau neeg chim siab" tam sim no "zoo siab heev". Cov Phenolic tsis nqus dej, cua sov tsis hloov pauv, muaj qee lub zog kho tshuab. Nws yooj yim ua, tab sis kuj muaj kev rwb thaiv tsev zoo, uas nyuam qhuav tshwm sim rau kev lag luam hluav taws xob, Ua ib qho kev tsim kho loj heev. Yog li ntawd, nws tau siv dav hauv kev tsim cov nres hluav taws xob, cov qhov hloov teeb, cov 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 ua noj, ua rau nws uacov tes tuav lauj kaub,cov tes tuav lauj kaubPeb muaj ntau hom kov ua noj ua haus uas ua los ntawm Bakelite.
