Epoxy resin board use characteristics

1. Noocyo kala duwan

Resins kala duwan, wakiilada daweynta, iyo hababka wax ka beddelka waxay ku dhawaad ​​​​la qabsan karaan shuruudaha codsiyada kala duwan ee foomka, iyo kala duwanaanshadu waxay noqon kartaa mid aad u hooseeya ilaa heerkul sare oo adag.

2. adhesion xoog leh

Kooxaha dabiiciga ah ee hydroxyl polar iyo curaarta ether ee silsiladda molecular ee resins epoxy waxay ka dhigaan mid aad ugu dheggan walxo kala duwan. Hoosudhaca resin epoxy waa hooseeyaa marka la daweynayo, iyo walbahaarka gudaha ka dhasha waa mid yar, kaas oo sidoo kale gacan ka geysta hagaajinta xoogga adhesion.

3. Daawaynta ku habboon

Dooro noocyo kala duwan oo dawooyin ah oo kala duwan, nidaamka resin epoxy ku dhawaad ​​waxaa lagu daweyn karaa inta u dhaxaysa heerkulka 0 ~ 180 ℃.

4. Yaraynta hoose

The reaction between the epoxy resin and the curing agent used is carried out by direct addition reaction or ring-opening polymerization reaction of epoxy groups in the resin molecule, and no water or other volatile by-products are released. Compared with unsaturated polyester resins and phenolic resins, they show very low shrinkage (less than 2%) during curing.

5. Guryaha makaanikada

Nidaamka resin epoxy ee la daweeyay wuxuu leeyahay sifooyin farsamo oo aad u wanaagsan.

6. Waxqabadka korontada

Nidaamka xabagta epoxy ee la daweeyay waa walxo dahaadhid aad u wanaagsan oo leh sifooyin koronto oo sarreeya, caabbinta daadinta dusha sare, iyo iska caabinta arc.
