Kagwiritsidwe Ntchito
Choyamwa cha ultraviolet UV-9 ndi ufa wopepuka wachikasu kapena woyera, womwe umadziwikanso kuti Sunscreen Agent No. 2 ndi BP-3. Ndi choyenera mapulasitiki osiyanasiyana monga polyvinyl chloride, polyvinylidene chloride, polymethyl methacrylate, unsaturated polyester, ABS resin, ndi cellulose resin. Kutalika kwake kwakukulu kwa mafunde ndi 280-340 nanometers, ndi mlingo wamba wa 0.1-1.5%. Chili ndi kukhazikika kwabwino kwa kutentha ndipo sichimawola pa 200°C. Chogulitsachi sichimayamwa kuwala kooneka, kotero ndi choyenera zinthu zowala komanso zowonekera. Chingagwiritsidwenso ntchito mu utoto ndi rabara yopangidwa. Monga choyamwa cha ultraviolet chochuluka kuchokera ku Chemicalbook, chili ndi ubwino wa kuyamwa kwakukulu, kusapha poizoni, kusatulutsa mphamvu, komanso kukhazikika kwabwino ku kuwala ndi kutentha. Choyamwa cha ultraviolet UV-9 chimatha kuyamwa UV-A ndi UV-B. Ndi Class Ⅰ sunscreen yovomerezedwa ndi US FDA, ndipo imagwiritsidwa ntchito nthawi zambiri ku United States ndi mayiko aku Europe. UV-9 imagwiritsidwa ntchito kwambiri mu zodzoladzola zoteteza ku dzuwa monga mafuta odzola ku dzuwa, mafuta odzola, mkaka, ma emulsion, ndi mafuta. Ingagwiritsidwenso ntchito ngati mankhwala oletsa kusinthasintha kwa mtundu wa zinthu zomwe zimasintha mtundu chifukwa cha kuwala kwa dzuwa. Kuphatikiza apo, chifukwa chogwirizana bwino ndi mapulasitiki ndi ma resin ambiri, nthawi zambiri imagwiritsidwa ntchito m'magawo ambiri monga PVC ndi polyester yosakhuta.
Chotsukira UV UV-9 ndi chotsukira UV chokhala ndi ma spectrum ambiri chomwe chili ndi ubwino monga kuyamwa kwambiri, kusawononga poizoni, kusatulutsa mphamvu ya teratogenic, komanso kukhazikika bwino pa kuwala ndi kutentha. Chimatha kuyamwa UV-A ndi UV-B. Ndi chotsukira dzuwa cha Class Ⅰ chovomerezedwa ndi US FDA, ndipo chimagwiritsidwa ntchito nthawi zambiri ku United States ndi Europe. Chimagwiritsidwa ntchito kwambiri mu zodzoladzola zoteteza ku dzuwa monga zotsukira dzuwa, mafuta, mafuta odzola, emulsions, mafuta, ndi zina zotero, ndipo chingagwiritsidwenso ntchito ngati choletsa kusinthika kwa mtundu wa zinthu zomwe zimasintha mtundu chifukwa cha kuwala kwa dzuwa.
Ma Benzophenone ultraviolet absorbers ndi abwino kwambiri okhazikika pa mapulasitiki opangidwa monga polyethylene, okhala ndi mlingo wa 0.5-1.5%. Angagwiritsidwenso ntchito mu utoto, utoto, makampani opaka utoto, parafini woyengedwa bwino, komanso zodzoladzola za tsiku ndi tsiku.
Amagwiritsidwa ntchito mu mapulasitiki, ulusi wa mankhwala, utoto ndi zinthu zamafuta, ndipo ndi oyenera makamaka zinthu zowala komanso zowonekera bwino.
Itha kugwiritsidwa ntchito mu utoto ndi zinthu zosiyanasiyana za pulasitiki, ndipo imagwira ntchito bwino kwambiri pa polyvinyl chloride, polyester, acrylic, resin, polystyrene, ndi mipando yowonekera bwino, ndi zina zotero. Ndi chowonjezera chabwino kwambiri chokongoletsera. Mlingo wake ndi 0.1-0.5%.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
