Cov ntaub ntawv yas:
Cov yas feem ntau siv tsis yog ib feem, nws yog tsim los ntawm ntau cov ntaub ntawv.Ntawm lawv, siab molecular polymers (los yog hluavtaws resins) 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, thiab stabilizers, yuav tsum tau ntxiv rau cov khoom siv molecular siab., Colorants, antistatic agents, thiab lwm yam, tuaj yeem ua cov yas nrog kev ua haujlwm zoo.
Yas additives, tseem hu ua yas additives, yog cov tebchaw uas yuav tsum tau ntxiv los txhim kho kev ua tau zoo ntawm cov polymer (synthetic resin) los yog txhim kho cov kev ua tau zoo ntawm cov resin nws tus kheej thaum lub polymer (synthetic resin) ua tiav.Piv txwv li, txhawm rau txo cov molding kub ntawm polyvinyl chloride resin, cov yas yog ntxiv kom cov khoom muag muag;Lwm qhov piv txwv yog ntxiv cov foaming tus neeg sawv cev rau kev npaj lub teeb yuag, kev co-resistant, kub-insulating, thiab suab-insulating npuas;Qhov kub decomposition yog ze heev rau molding ua kub, thiab molding tsis tuaj yeem ua tiav yam tsis ntxiv cov cua sov stabilizers.Yog li ntawd, yas additives occupies ib tug tshwj xeeb txoj hauj lwm tseem ceeb nyob rau hauv yas molding ua.
Plastics yog cov khoom sib xyaw polymer (macromolecules), feem ntau hu ua plastics lossis resins, uas yog polymerized los ntawm monomers ua raw khoom los ntawm kev sib ntxiv polymerization lossis polycondensation cov tshuaj tiv thaiv.Cov muaj pes tsawg leeg thiab cov duab tuaj yeem hloov pauv dawb.Nws yog tsim los ntawm hluavtaws resins thiab fillers.Plasticizer, stabilizer, lubricant, pigment thiab lwm yam additives.
