Chimassorb 944 Cas 71878-19-8
Chimassorb 944 (CAS 71878-19-8) ndi mankhwala oletsa kuwala kwa amine (HALS) omwe ali ndi kulemera kwakukulu kwa mamolekyulu.
UV Absorber 944 ndi cholimbitsa kuwala kwa amine cholemera kwambiri chomwe chimapangidwa ndi polymer, chokhala ndi kusasinthasintha kochepa, kukana kusamuka, komanso kukana kutentha kwambiri. Magulu a amine oletsedwa omwe ali mu kapangidwe ka mankhwala ka UV 944 amatha kugwira bwino ma free radicals, motero amatenga gawo pakukhazikika kwa kuwala.
Kugwiritsa ntchito bwino kwa polymeric kunalepheretsa kukhazikika kwa kuwala kwa amine, kuchepa kwa volatilization, kusamuka kochepa, kukhazikika kwa kutentha komanso mphamvu yotsutsana ndi okosijeni, kumagwirizana ndi ma antioxidants ndi ma UV absorbers. UV Absorber 944 ingagwiritsidwe ntchito pa ma polyolefins, ma olefin copolymers, komanso pa ma polyphenylene ether complexes, polyoxymethylene, amides, zofewa ndi zolimba za PVC ndi PVC.

Chimassorb 944 imatha kupititsa patsogolo kukhazikika kwa kuwala kwa zinthu zopyapyala, makamaka zinthu zopangidwa ndi ulusi ndi filimu. UV 944 imagwiranso ntchito pazinthu zokhuthala zopingasa komanso zinthu zopangidwa ndi polyethylene.
Magawo ogwiritsira ntchito a UV Absorber 944 ndi monga mapulasitiki a polyolefin (monga PP, PE), olefin copolymers (monga EVA), ndi zosakaniza za polypropylene (PP) ndi elastomers, ndi zina zotero. Kuphatikiza apo, UV Absorber 944 ingagwiritsidwenso ntchito mu polyoxymethylene (POM), polyamide (PA), polyurethane (PU), PVC yosinthasintha komanso yolimba, ndi zosakaniza za PVC. Chimassorb 944 imathandizanso kwambiri pakugwiritsa ntchito ma elastomers ndi zomatira zopangidwa ndi styrene.
✅Chimassorb 944 ili ndi kuwala kolimba bwino ndipo imatha kuteteza kuwonongeka, kusintha mtundu ndi kusokonekera kwa mapulasitiki chifukwa cha kuwala kwa ultraviolet.
✅UV Absorber 944 ili ndi mphamvu zabwino zoletsa kutulutsa zinthu ndipo siitha kusuntha kuchokera ku pulasitiki ikagwiritsidwa ntchito kwa nthawi yayitali.
✅UV 944 imagwirizana bwino kwambiri ndipo imatha kufalikira mofanana m'thupi la pulasitiki popanda kusokoneza magwiridwe antchito ake komanso mphamvu zake zakuthupi komanso zamakanika.
20kgs/ng'oma, matani 9/chidebe cha 20'.
