Khoom Khoom
- High -kub tsis kam: Phenolic resins tuaj yeem tiv taus qhov kub siab tshaj 200 degree. Piv txwv li, 2402 phenolic resin (CAS No. 9003-35-4) tsim los ntawm Jinan Shanhai Chemical Technology Co., Ltd. muaj qhov muag muag ntawm 90-100℃thiab tsim nyog rau kev txhim kho tackiness thaum lub sij hawm roj hmab vulcanization nyob rau hauv siab -kub ib puag ncig.
- nplaim retardancy: Cov qauv molecular muaj benzene rings uas tsim ib txheej carbonized thaum combustion. Zhejiang Zili Polymer Chemical Materials Co., Ltd. siv cov cuab yeej no hauv nws cov phenolic resin tsim rau photoresists, ua cov kua qaub - resistant txheej nyob rau hauv integrated circuits.
- Modifiability: Cov ntawv thov tuaj yeem nthuav dav los ntawm cov txheej txheem xws li sulfonation lossis rosin hloov kho. Piv txwv li, sulfonated phenolic resin los ntawm Renqiu Shuangcheng Chemical Products Factory yog siv los ua cov kua dej -tsis muaj tus neeg saib xyuas hauv cov dej drilling; nws yog cov pa phem -dawb thiab muaj pH ntawm 7.
Txheej txheem ntau lawm
Cov kauj ruam ib txwm muaj xws li:
- Raw khoom proportioning: Cov molar piv ntawm phenol rau formaldehyde feem ntau yog 1: 1.2-2.5. Shandong Apu Chemical Technology's 2402 phenolic resin ntiav ib tug *p*-tert-butylphenol-formaldehyde formulation nrog phenol dawb cov ntsiab lus tsawg dua los yog sib npaug rau 1.5%.
- Cov tshuaj tiv thaiv polycondensation: Ua los ntawm cov kua qaub lossis alkaline catalysts ntawm qhov ntsuas kub ntawm 80-100 degree. Cov kua phenolic resin los ntawm Wuhan Jiyesheng Chemical, piv txwv li, ua tiav viscosity ntawm 700 mPa·s.
- Post-kev ua: Lub cev qhuav dej ua raws li granulation lossis pulverization. Jinan Dahui Chemical Technology lub thermosetting phenolic resin, piv txwv li, muaj nyob rau hauv ntau hom, nrog rau cov hmoov thiab granules.
