Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm 3240 epoxy cob board

3240 epoxy resin board zoo

1. Ntau hom ntawv. Ntau yam resins, kho tus neeg sawv cev, thiab hloov kho cov txheej txheem tuaj yeem hloov kho kom tau raws li qhov xav tau ntawm ntau daim ntawv thov ntawm daim ntawv, thiab qhov ntau tuaj yeem yog los ntawm qis viscosity mus rau qhov siab melting point khib nyiab.

2. Muaj zog nplaum. Cov pab pawg hydroxyl ncov qaumteb qabteb thiab cov ether bonds hauv cov saw hlau molecular ntawm epoxy resins ua rau nws nplaum rau ntau yam tshuaj. Kev nqaim ntawm epoxy resin yog qis thaum kho, thiab kev nyuab siab sab hauv tsim tawm me me, uas tseem pab txhim kho lub zog ua kom khov.

3. Yooj yim kho. Xaiv ntau yam sib txawv ntawm cov neeg sawv cev kho kab mob, cov txheej txheem epoxy tuaj yeem yuav luag tau kho hauv qhov kub ntawm 0 ~ 180 ℃.

4. Tsawg shrinkage. Cov tshuaj tiv thaiv ntawm epoxy resin thiab curing tus neeg sawv cev 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 volatile by-products emissions. Piv nrog unsaturated polyester resins thiab phenolic resins, lawv pom tsawg heev shrinkage (tsawg dua 2%) thaum kho.

5. Kev ua haujlwm hluav taws xob. Cov txheej txheem kho epoxy resin yog cov khoom siv zoo heev uas muaj cov khoom siv hluav taws xob zoo, tiv thaiv kom tsis txhob xau, thiab tiv taus arc.

6. Cov khoom siv dag zog. Cov txheej txheem kho epoxy resin muaj cov cuab yeej zoo heev.

Disadvantages ntawm epoxy resin board

Lub epoxy resin board muaj tsis txaus rigidity, tsis zoo rau lub sij hawm ntev kub tsis kam, thiab nws yog nquag laus tom qab ib tug ntev lub sij hawm ntawm kev siv.
