FRP Hand Layup Khoom

Gel txheej
Gel txheej muab rau koj smoothness xav tau rau cov khoom. Nws feem ntau yog ib txheej nyias ntawm cov resin uas yog li ntawm 0.3 hli ntawm qhov chaw ntawm cov khoom. Ntxiv cov pigments tsim nyog rau cov resin, thiab cov xim yog kev cai muaj. Cov gel txheej tsim cov txheej txheem tiv thaiv los tiv thaiv cov khoom los ntawm kev sib cuag nrog dej thiab tshuaj. Yog tias nws nyias dhau lawm, cov qauv fiber ntau yuav pom. Yog hais tias nws yog tuab heev, yuav muaj crazing thiab lub hnub qub tawg ntawm cov khoom nto.

Nto mat txheej
