phenolic resin rau cov khoom sib txhuam
Cov resins rau bonded abrasives yog hmoov thiab kua, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov khoom sib txawv. Cov koob no tau txais cov khoom siv ntau lawm thiab kev ua haujlwm. Nrog cov qauv tsim nruj, qhov hnyav molecular zoo thiab faib cov txheej txheem tswj, nws ua rau kev faib cov resin molecular mus txog qhov zoo tagnrho. Cov hmoov resin yog tus cwj pwm muaj zog viscosity, txhua yam muaj zog, abrasion tsis kam, kub tsis kam thiab ntub sib tsoo stability. Raws li tus neeg sawv cev ntub dej zoo heev, cov kua nplaum muaj qhov ua haujlwm zoo wetting thiab zoo faib miscibility. Nws ua rau cov kua resin nrog cov av noo zoo los ntawm kev ua haujlwm tshwj xeeb. Nyob rau hauv high humidity tej yam kev mob, cov resin yuav tsis yuav caking, thiab nrog siab zog thiab siab sib tsoo kev ua tau zoo, nws yog ib tug zoo heev khoom xaiv los ntawm feem ntau ntawm cov sib tsoo log manufacturers.

Ntim thiab khaws cia
Flake / hmoov: 20 kg / hnab, 25kg / hnab, Resin yuav tsum muab cia rau hauv qhov chaw txias, qhuav thiab qhov cua zoo. Lub neej cia yog 4-6 lub hlis hauv qab 20 ℃. Nws cov xim yuav tsaus ntuj nrog lub sijhawm khaws cia, uas yuav tsis cuam tshuam rau qib resin.
