Cov xwm txheej ntawm daim ntawv thov ntawm cov khoom siv xim epoxy hauv pem teb uas siv dej

Cov xim pleev hauv pem teb epoxy uas muaj dej yog cov khoom siv txheej hauv pem teb ob yam uas tsis ua rau ib puag ncig puas tsuaj, siv dej ua cov tshuaj yaj thiab cov tshuaj sib kis. Nws muaj cov tshuaj epoxy uas muaj dej, cov tshuaj kho kom zoo, cov xim thiab cov khoom sau, thiab cov khoom ntxiv. Nws muab cov epoxy ib txwm muaj zog nrog VOC qis thiab kev nyab xeeb siab ntawm cov txheej txheem dej.

Cov xim pleev hauv pem teb epoxy uas muaj dej yog cov khoom siv hloov hauv pem teb uas tsim los teb rau cov cai ib puag ncig nruj dua thiab cov kev cai noj qab haus huv uas tau hloov kho dua tshiab. Nws daws qhov tsis zoo ntawm cov xim pleev hauv pem teb epoxy uas muaj kuab tshuaj, xws li kev hloov pauv sai, kev kub hnyiab, ntxhiab tsw loj ntawm kev tsim kho, thiab kev hloov pauv tsis zoo rau cov khoom ntub. Nws tau dhau los ua qhov kev xaiv tseem ceeb rau cov chaw rhiab heev xws li tsev kho mob, cov chaw ua zaub mov, thiab cov chaw nres tsheb hauv av.

Cov qauv tseem ceeb thiab lub hauv paus ntsiab lus

• Cov khoom tseem ceeb: Cov tshuaj epoxy ua los ntawm dej (uas tawg ua tej daim me me hauv dej) + cov tshuaj tua kab mob epoxy ua los ntawm dej + cov xim ua haujlwm (xws li cov zaub mov tshwj xeeb) + cov khoom ntxiv;
• Txoj kev tsim cov yeeb yaj kiab: Nws yog ib qho ntawm ntau lub kaw lus dispersion, kev kho tsis sib xws - thaum lub sijhawm ua dej evaporation, cov resin thiab cov neeg sawv cev kho cov khoom sib nkag mus, sib kis thiab sib txuas, thaum kawg tsim cov qauv txheej txheem network;
• Qhov sib txawv tseem ceeb: Txawv ntawm "qib molecular homogeneous reaction" ntawm cov kuab tshuaj epoxy, nws qib kev kho yog cuam tshuam ncaj qha los ntawm qhov loj me ntawm cov khoom me me, kev sib raug zoo ntawm ob theem, thiab qib kev sib xyaw ua ke.
