Gwiritsani ntchito
Izi ndi stabilizer kuwala ndi ntchito zabwino, amatha kuyamwa UV cheza wa 240-340 nm kutalika kwa mawonekedwe a kuwala mtundu, nontoxic, ngakhale zabwino, kuyenda yaing'ono, processing zosavuta etc. Ikhoza kuteteza polima mpaka pazipita zake, kumathandiza kuchepetsa mtundu. Ikhozanso kuchedwetsa chikasu ndikulepheretsa kutaya kwa thupi lake. Amagwiritsidwa ntchito kwambiri ku PE, PVC, PP, PS, PC organic glass, polypropylene fiber, ethylene-vinyl acetate etc. Komanso, ali ndi zotsatira zabwino kwambiri za kuwala kwa kuyanika phenol aldehyde, varnish ya mowa ndi acname, polyurethane, acrylate, expoxnamee etc.
Mlingo wamba
Mlingo wake ndi 0.1% -0.5%.
1.Polypropylene: 0.2-0.5wt% kutengera kulemera kwa polima
2.Zithunzi za PVC
PVC yolimba: 0.5wt% kutengera kulemera kwa polima
PVC yapulasitiki: 0.5-2 wt% kutengera kulemera kwa polima
3.Polyethylene: 0.2-0.5wt% kutengera kulemera kwa polima
Kulongedza ndi Kusunga
Phukusi: 25KG/CARTON
Kusungirako: Kukhazikika pamalopo, kusunga mpweya wabwino komanso kutali ndi madzi ndi kutentha kwakukulu.
