1. Phenolic resin

Phenolic resin tseem hu ua bakelite, tseem hu ua bakelite hmoov, lus Askiv lub npe phenolic resin, PF luv luv, tshwj xeeb lub ntiajteb txawj nqus 1.25 ~ 1.30, yog lub npe dav dav ntawm hluavtaws cob tau los ntawm polymerization ntawm phenol thiab aldehyde. Nws muaj cov molecules dawb thiab yog xim liab, thiab feem ntau muag hauv khw nrog cov xim ntxiv los qhia cov xim xws li liab, daj, dub, ntsuab, xim av, xiav, thiab lwm yam, nyob rau hauv daim ntawv ntawm granules thiab hmoov. Resistant rau qaug zog acid thiab tsis muaj zog puag, nws yuav decompose nyob rau hauv cov ntaub ntawv ntawm muaj zog acid thiab corrode nyob rau hauv cov ntaub ntawv ntawm muaj zog alkali. Insoluble nyob rau hauv dej, soluble nyob rau hauv acetone, cawv thiab lwm yam organic solvents. Ruaj khov rau dej, qaug zog acid thiab qaug zog hauv paus daws. Resin ua los ntawm polycondensation ntawm phenol thiab formaldehyde nyob rau hauv catalyst tej yam kev mob, neutralization thiab dej ntxuav. Vim muaj cov catalysts sib txawv, lawv tuaj yeem muab faib ua ob pawg: thermosetting thiab thermoplastic. Feem ntau suav nrog: novolac resin, thermosetting phenolic resin thiab roj-soluble phenolic resin.

Thermosetting phenolic resins (los yog ib-kauj ruam phenolic resins) tuaj yeem ua rau hauv cov khoom khib nyiab, kua thiab emulsions raws li qhov xav tau, thiab tuaj yeem sib txuas thiab kho yam tsis muaj tus neeg sawv cev sib txuas hauv qab kev ua ntawm cua sov lossis (thiab) kua qaub. Txhawm rau coj cov resin synthesis thiab molding ua, cov txheej txheem kho feem ntau muab faib ua peb theem: A, B, thiab C. Cov prepolymer nrog cov khoom soluble thiab fusible hu ua A-theem phenolic resin; lub xeev kawg ntawm kev sib txuas thiab kev kho yog hu ua C-theem phenolic resin; Nws swells nyob rau hauv cov kuab tshuaj tab sis tsis tag yaj, thiab yog softened tab sis tsis melted los ntawm tshav kub. Lub xeev hu ua B-theem phenolic resin. Lub viscosity ntawm thermosetting phenolic resin maj mam nce thaum lub sij hawm cia, thiab thaum kawg nws tuaj yeem dhau los ua ib qho insoluble thiab infusible C-theem resin. Yog li ntawd, nws lub sij hawm cia feem ntau tsis ntau tshaj 3 mus rau 6 lub hlis. Thermosetting phenolic resins tuaj yeem siv rau hauv kev tsim khoom ntawm ntau yam laminated plastics, compression hmoov thiab laminated plastics; nyob rau hauv kev tsim cov varnishes los yog insulating thiab corrosion-resistant coatings; nyob rau hauv kev tsim cov khoom siv niaj hnub thiab cov khoom dai; nyob rau hauv kev tsim cov suab rwb thaiv tsev thiab cov ntaub ntawv rwb thaiv tsev kub, thiab lwm yam. Cov khoom siv hluav taws xob muaj hluav taws xob ntau, cov nplaum nplaum thiab lwm yam hloov kho polymers.

2. Cov khoom tseem ceeb ntawm phenolic resin

2.1 Kev ua haujlwm siab kub

Qhov tseem ceeb tshaj plaws ntawm phenolic resins yog lawv qhov kub thiab txias tsis kam, uas tswj lawv cov qauv kev ncaj ncees thiab qhov ruaj khov ntawm qhov ntev txawm tias qhov kub thiab txias heev. Nws yog vim li no tias phenolic resins tau siv nyob rau hauv qee qhov chaw kub kub, xws li cov khoom siv hluav taws xob, cov ntaub ntawv sib txhuam, cov nplaum thiab cov chaw tsim khoom lag luam.

2.2 Bond zog

Ib qho tseem ceeb daim ntawv thov ntawm phenolic resin yog raws li ib tug binder. Phenolic resins muaj ntau yam thiab sib xws nrog ntau yam organic thiab inorganic fillers. Nrog rau txoj cai tsim ntawm phenolic resins, ntub dej yog tshwj xeeb ceev ceev. Thiab tom qab kev sib txuas ntawm kev sib txuas, nws tuaj yeem muab cov khoom siv uas xav tau, kev ua haujlwm kub thiab hluav taws xob rau cov cuab yeej abrasive, cov ntaub ntawv refractory, cov ntaub ntawv sib txhuam thiab cov hmoov Bakelite.

Cov dej-soluble phenolic resins los yog cawv-soluble phenolic resins yog siv los impregnate daim ntawv, paj rwb, iav, asbestos thiab lwm yam khoom zoo sib xws los muab cov neeg kho tshuab lub zog, hluav taws xob khoom, thiab lwm yam. Piv txwv xws li hluav taws xob rwb thaiv tsev thiab mechanical lamination manufacturing, clutch discs. thiab lim cov ntaub ntawv rau automotive lim.

2.3 High carbon residual rate

Nyob rau hauv cov xwm txheej ntawm inert roj ntawm qhov kub txog li 1000 degree, phenolic resin yuav tsim kom muaj cov pa roj carbon residue, uas muaj txiaj ntsig zoo los tswj cov qauv kev ruaj ntseg ntawm phenolic resin. Cov yam ntxwv ntawm phenolic resin no kuj yog ib qho tseem ceeb vim li cas nws tuaj yeem siv rau hauv cov khoom siv refractory.

2.4 Cov pa luam yeeb tsawg thiab tsis muaj tshuaj lom

Piv nrog rau lwm cov txheej txheem resin, phenolic resin systems muaj qhov zoo ntawm cov pa luam yeeb tsawg thiab tsis muaj tshuaj lom. Nyob rau hauv qhov kev tshwm sim ntawm combustion, lub scientifically tsim phenolic resin system yuav maj mam decompose los tsim hydrogen, hydrocarbons, dej vapor thiab carbon oxides. Cov pa luam yeeb me me yog tsim thaum lub sij hawm decomposition, thiab cov toxicity kuj tseem tsawg. Cov yam ntxwv no ua rau phenolic resins haum rau thaj chaw uas muaj kev thauj mus los rau pej xeem nruj heev thiab kev nyab xeeb, xws li mines, guardrails thiab kev tsim kho.

2.5 Tshuaj tiv thaiv

Tus ntoo khaub lig-txuas phenolic resin resists tej tshuaj decomposition. Xws li roj av, roj av, cawv, glycol thiab ntau yam hydrocarbons.
