Yuav ua li cas hais txog epoxy resin board khoom

Resin, hardener, modifier systems muaj kom haum rau txhua daim ntawv thov yuav tsum tau, xws li los ntawm tsawg viscosities mus rau siab melting point solids. Ntau yam tshuaj tua kab mob yog siv los kho, thiab cov txheej txheem epoxy resin tuaj yeem kho yuav luag ntawm qhov kub ntawm 0 txog 180 ° C.

1. Muaj zog adhesion

Lub hav zoov ntawm polar hydroxyl thiab ether bonds muaj nyob rau hauv cov saw molecular ntawm epoxy resin ua rau nws muaj siab adhesion rau ntau yam khoom. Epoxy resins muaj tsawg shrinkage thaum kho thiab tsis tshua muaj kev ntxhov siab sab hauv, uas kuj pab txhim kho adhesion zog.

2. Lub zog luv luv

Cov tshuaj tiv thaiv ntawm epoxy resin thiab curing tus neeg sawv cev siv yog nqa tawm los ntawm ib tug ncaj qha ntxiv cov tshuaj tiv thaiv los yog lub nplhaib-qhib polymerization cov tshuaj tiv thaiv ntawm epoxy pab pawg neeg nyob rau hauv lub resin molecule, thiab tsis muaj dej los yog lwm yam volatile by-products raug tso tawm. Lawv pom qhov qis qis heev (tsawg dua 2%) thaum kho dua piv rau unsaturated polyester resins thiab phenolic resins.

3. Mechanical muaj nuj nqi

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

4. Hluav taws xob muaj nuj nqi

Lub kho epoxy resin system yog ib qho zoo heev insulating cov ntaub ntawv uas muaj siab dielectric zog, nto to resistance thiab arc kuj.

5. Tshuaj lom neeg ruaj khov

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

6. Scale stability

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

7. Pwm resistant

Kho epoxy systems yog resistant rau feem ntau pwm thiab yuav siv tau nyob rau hauv hnyav tropical tej yam kev mob.
