Cov yas peb feem ntau siv tsis yog cov khoom ntshiab, nws yog tsim los ntawm ntau cov ntaub ntawv.Ntawm lawv, siab molecular polymers yog cov khoom tseem ceeb ntawm cov yas.Tsis tas li ntawd, txhawm rau txhim kho kev ua tau zoo ntawm cov yas, ntau yam khoom siv, xws li muab tub lim, plasticizers, lubricants, stabilizers, colorants, thiab lwm yam, yuav tsum tau ntxiv rau cov polymer.Kev ua haujlwm zoo yas.
Cov hnab yas hluavtaws: Cov khoom siv hluav taws xob siab molecular, tseem hu ua hluavtaws cob, yog cov khoom tseem ceeb tshaj plaws ntawm cov yas, thiab nws cov ntsiab lus hauv cov yas feem ntau yog 40% txog 100%.Vim muaj cov ntsiab lus loj thiab cov khoom ntawm cov resins uas feem ntau txiav txim siab cov khoom ntawm plastics, tib neeg feem ntau suav hais tias cov resins yog synonymous nrog plastics.
Cov hnab yas ntim khoom: cov khoom ntim kuj tseem hu ua cov khoom ntim khoom, uas tuaj yeem txhim kho lub zog thiab kub tsis kam ntawm cov yas thiab txo cov nqi.Piv txwv li, ntxiv ntoo hmoov rau phenolic resin tuaj yeem txo tus nqi zoo heev, ua phenolic yas yog ib qho ntawm cov yas uas pheej yig tshaj plaws, thiab tib lub sijhawm, nws tuaj yeem txhim kho lub zog txhua yam.Fillers tuaj yeem muab faib ua cov organic fillers thiab inorganic fillers, yav dhau los xws li ntoo hmoov, rags, ntawv thiab ntau yam ntaub fibers, thiab lwm yam, tom kawg xws li iav fiber, diatomaceous ntiaj teb, asbestos, carbon dub thiab lwm yam.
Cov hnab yas yas yas: Cov yas yas tuaj yeem ua kom cov yas thiab cov mos mos ntawm cov yas, txo cov brittleness, thiab ua kom cov yas yooj yim rau kev ua thiab cov duab.Plasticizers feem ntau yog cov resin-miscible, tsis muaj tshuaj lom, tsis muaj ntxhiab, siab-boiling organic tebchaw uas ruaj khov rau lub teeb thiab kub.Feem ntau siv yog phthalates.
Lub hnab yas stabilizer: Txhawm rau tiv thaiv cov khoom siv hluavtaws los ntawm kev decomposed thiab rhuav tshem los ntawm lub teeb thiab cua sov thaum ua thiab siv, thiab ua kom lub neej ntev, lub stabilizer yuav tsum tau ntxiv rau cov yas.Feem ntau siv yog stearate, epoxy resin thiab lwm yam.
Cov hnab yas xim xim: Cov xim tuaj yeem muab cov yas ntau yam xim ci, zoo nkauj.Organic dyes thiab inorganic pigments feem ntau yog siv los ua cov xim.
Lub hnab yas lubricant: Lub luag haujlwm ntawm cov roj nplaum yog los tiv thaiv cov yas los ntawm kev ua raws li cov hlau pwm thaum lub sij hawm molding, thiab tib lub sij hawm ua rau saum npoo ntawm cov yas du thiab zoo nkauj.Feem ntau siv lubricants yog stearic acid thiab nws cov calcium thiab magnesium ntsev.
Ntxiv nrog rau cov khoom siv saum toj no, cov nplaim hluav taws kub, cov khoom ua npuas dej, cov tshuaj tiv thaiv kab mob, thiab lwm yam kuj tuaj yeem muab ntxiv rau cov yas kom tau raws li cov ntawv thov sib txawv.
