Qhov zoo ntawm epoxy cob board

1. Muaj zog adhesion

Lub hauv paus ntsiab lus ntawm polar hydroxyl pawg thiab ether bonds nyob rau hauv cov saw molecular ntawm epoxy resins ua rau nws nplaum heev rau ntau yam khoom. Lub shrinkage ntawm epoxy resin yog tsawg thaum kho, thiab cov kev ntxhov siab sab hauv tsim yog me me, uas kuj pab txhim kho lub zog adhesion.

2. Muaj zog shrinkage

Cov tshuaj tiv thaiv ntawm epoxy resin thiab tus neeg sawv cev kho siv yog ua los ntawm cov tshuaj tiv thaiv ncaj qha los yog lub nplhaib-qhib polymerization cov tshuaj tiv thaiv ntawm epoxy pawg nyob rau hauv cov molecule resin, thiab tsis muaj dej los yog lwm yam khoom los ntawm cov khoom tsis haum. Piv nrog unsaturated polyester resins thiab phenolic resins, lawv pom tsawg heev shrinkage (tsawg dua 2%) thaum kho.

3. Kev ua haujlwm hluav taws xob

Cov txheej txheem kho epoxy resin yog cov khoom siv insulating zoo heev nrog cov khoom siv hluav taws xob siab, qhov dej tsis zoo, thiab arc tsis kam.

4. Mechanical zog

Cov kho epoxy resin system muaj cov cuab yeej zoo heev.

5. Tshuaj lom neeg ruaj khov

Feem ntau, kho epoxy resin system muaj zoo alkali tsis kam, acid kuj thiab hnyav kuj. Zoo li lwm yam khoom ntawm cov kab mob epoxy kho tau, cov tshuaj lom neeg ruaj khov kuj yog nyob ntawm cov khoom siv thiab cov neeg ua haujlwm kho. Kev xaiv tsim nyog ntawm epoxy resin thiab tus neeg sawv cev kho tuaj yeem ua rau nws muaj tshuaj lom neeg tshwj xeeb.

6. Dimensional stability

Kev sib xyaw ua ke ntawm ntau yam ntawm cov khoom saum toj no muab cov txheej txheem epoxy resin zoo qhov ruaj khov thiab ua haujlwm ntev.

7. pwm kuj

Cov kho epoxy resin system yog resistant rau feem ntau pwm thiab yuav siv tau nyob rau hauv hnyav tropical tej yam kev mob.
