Gwiritsani ntchito
Chogulitsachi ndi chokhazikika bwino komanso chogwira ntchito bwino, chomwe chimatha kuyamwa kuwala kwa UV kwa kutalika kwa 240-340 nm ndi mawonekedwe a mtundu wowala, wopanda poizoni, wogwirizana bwino, kuyenda pang'ono, kukonzedwa kosavuta ndi zina zotero. Chimatha kuteteza polima mpaka pamlingo wake wapamwamba, chimathandiza kuchepetsa mtundu. Chingathenso kuchedwetsa chikasu ndikulepheretsa kutayika kwa ntchito yake yakuthupi. Chimagwiritsidwa ntchito kwambiri pa PE, PVC, PP, PS, PC organic glass, polypropylene fiber, ethylene-vinyl acetate ndi zina zotero. Kuphatikiza apo, chili ndi mphamvu yabwino kwambiri yokhazikika pa kuumitsa phenol aldehyde, varnish ya mowa ndi acname, polyurethane, acrylate, expoxnamee ndi zina zotero.
Mlingo wochuluka
Mlingo wake ndi 0.1% - 0.5%.
1.Polypropylene: 0.2-0.5wt% kutengera kulemera kwa polima
2.PVC
PVC yolimba: 0.5wt% kutengera kulemera kwa polima
PVC yopangidwa ndi pulasitiki: 0.5-2 wt% kutengera kulemera kwa polima
3.Polyethylene: 0.2-0.5wt% kutengera kulemera kwa polima
Kulongedza ndi Kusunga
Phukusi: 25KG/BOTANI
Kusungirako: Kokhazikika m'nyumba, kusunga mpweya wabwino komanso kutali ndi madzi ndi kutentha kwambiri.
