Qhia Taw Qhia Silicone Roj

Cov roj Silicone feem ntau yog hais txog cov khoom lag luam polysiloxane ua cov khoom ua kua uas tseem ua kua rau hauv chav tsev kub. Feem ntau muab faib ua ob hom: methyl silicone roj thiab hloov roj silicone. Cov roj ntsha feem ntau siv cov roj silicone roj-methyl silicone roj, tseem hu ua silicone roj zoo tib yam, nws cov pawg organic yog txhua yam methyl, methyl silicone roj muaj tshuaj lom neeg zoo, rwb thaiv tsev, thiab cov khoom zoo hydrophobic. Nws tau los ntawm hydrolyzing dimethyldichlorosilane nrog dej kom tau txais thawj lub nplhaib polycondensation lub cev. Lub nplhaib lub cev tau tawg thiab txhim kho kom tau txais lub nplhaib lub cev qis, thiab tom qab ntawd lub nplhaib lub cev, tus neeg sawv cev capping, thiab catalyst tau muab tso ua ke kom tau txais lub nplhaib polycondensation. Kev sib xyaw ntawm cov tshuaj sib txawv polymerization tuaj yeem tau los ntawm lub tshuab nqus distillation kom tshem tawm cov tshuaj yaug qis.
