Kampani ya Shanghai Deborn Co., Ltd. yakhala ikugwira ntchito yogulitsa zowonjezera mankhwala kuyambira 2013, yomwe ili ku Pudong New District ku Shanghai.
Deborn imagwira ntchito yopereka mankhwala ndi mayankho a nsalu, mapulasitiki, zokutira, utoto, zamagetsi, mankhwala, nyumba ndi mafakitale osamalira anthu.
UV-5411 ndi chida chapadera chokhazikitsa zithunzi chomwe chimagwira ntchito bwino m'njira zosiyanasiyana za polymeric: makamaka mu ma polyester, ma polyvinyl chloride, ma styrenics, ma acrylic, ma polycarbonate, ndi ma polyvinyl butyal. UV-5411 imadziwika kwambiri chifukwa cha kuyamwa kwa UV kwamitundu yosiyanasiyana, mtundu wake wochepa, kusasinthasintha pang'ono, komanso kusungunuka bwino kwambiri. Ntchito zambiri zomwe zimagwiritsidwa ntchito zimaphatikizapo kupanga, mapepala, ndi zinthu zowunikira pazenera, zizindikiro, zapamadzi ndi zamagalimoto. Ntchito zapadera za UV-5411 zimaphatikizapo zokutira (makamaka ma mosets pomwe kusasinthasintha kochepa kumakhala vuto), zinthu zojambulira zithunzi, zomatira, ndi zinthu zosalala.
UV 312 ndi chowongolera kuwala chothandiza kwambiri pa mapulasitiki osiyanasiyana ndi zinthu zina zachilengedwe kuphatikizapo ma polyester osakhuta, PVC (yosinthasintha komanso yolimba) ndi PVC plastisol.
Choyamwa UV chogwira ntchito bwino kwambiri cha PVC, PE, PP, ABS ndi ma polyester osakhuta.
Amagwiritsidwa ntchito pa ma polima osiyanasiyana komanso ntchito zake kuphatikizapo ma polyurethane (Spandex, TPU, RIM etc.), mapulasitiki aukadaulo (PET, PC, PC/ABS, PA, PBT etc.). Amapereka kukhazikika kwa kutentha kwambiri. Amapereka mawonekedwe abwino kwambiri onyamula kuwala komanso amagwirizana bwino komanso kusungunuka ndi ma polima ndi zosungunulira zosiyanasiyana.
Zophimba za polyurethane zokhala ndi zigawo ziwiri, thovu lofewa la polyurethane ndi polyurethane thermoplastic elastomer, makamaka mu zinthu za polyurethane monga thovu la micro-cell, thovu la khungu losasinthika, thovu lolimba lachikhalidwe, thovu lolimba pang'ono, thovu lofewa, zokutira nsalu, zomatira zina, zomatira ndi ma elastomer ndi polyethylenechloride, vinyl polymer monga acrylic resin yokhala ndi kukhazikika kwabwino kwa kuwala. Imayamwa kuwala kwa UV kwa 300 ~ 330nm.
Chogulitsachi ndi chothandiza kuyamwa kuwala kwa ultraviolet komwe kumasungunuka m'madzi ndipo chili ndi mphamvu yochuluka komanso mphamvu yoyamwa kuwala ya 288nm. Chili ndi ubwino woyamwa bwino kwambiri, sichimayambitsa poizoni, sichimayambitsa ziwengo komanso sichimayambitsa kufooka, chimakhala cholimba bwino mu kuwala komanso chimakhala cholimba mu kutentha ndi zina zotero. Kuphatikiza apo, chimatha kuyamwa UV-A ndi UV-B, chomwe ndi choteteza ku dzuwa cha kalasi I, chomwe chimawonjezeredwa mu zodzoladzola ndi mlingo wa 5-8%.
Benzophenone-4 ndi yosungunuka m'madzi ndipo ikulimbikitsidwa chifukwa cha zinthu zambiri zoteteza ku dzuwa. Mayeso asonyeza kuti Benzophenone-4 imalimbitsa kukhuthala kwa ma gels kutengera polyacrylic acid (Carbopol, Pemulen) akamakhudzidwa ndi kuwala kwa UV. Kuchuluka kwake kochepera 0.1% kumapereka zotsatira zabwino. Imagwiritsidwa ntchito ngati chokhazikika cha ultra-violet mu ubweya, zodzoladzola, mankhwala ophera tizilombo ndi utoto wa lithographic plate. Tiyenera kudziwa kuti tBenzophenone-4 sigwirizana ndi mchere wa Mg, makamaka mu emulsions yamafuta amadzi. Benzophenone-4 ili ndi mtundu wachikasu womwe umakhala wolimba kwambiri mu alkaline ndipo ungasinthe chifukwa cha mitundu.
BP-2 ndi ya banja la benzophenone yomwe imalowa m'malo mwake yomwe imateteza ku kuwala kwa ultraviolet.
BP-2 imayamwa kwambiri m'madera a UV-A ndi UV-B, motero imagwiritsidwa ntchito kwambiri ngati fyuluta ya UV m'mafakitale okongoletsa komanso mankhwala apadera.
Ali ndi kulemera kwakukulu kwa mamolekyulu, sasinthasintha, amakana kutulutsa; amapangidwa mosavuta.
Choyamwa cha UV cha benzotriazole chomwe chingalepheretse kuwonongeka kwa okosijeni, kuteteza ulusi, ndikukweza mtundu wa zinthu zopangidwa ndi nsalu; uwu ndi mbadwo watsopano wa zoyamwa za UV zokhala ndi ukadaulo wovomerezeka ndipo zidapambana satifiketi yazinthu zofunika kwambiri m'boma mu 2007, zafika pamlingo wapadziko lonse lapansi.
Chogulitsachi chikuyenera mu Polyolefine, Polyvinyl chloride, galasi lachilengedwe ndi zina. Kutalika kwa mafunde okhuthala kwambiri ndi 270-400nm.
Chogulitsachi chimagwira ntchito bwino kwambiri pokhazikitsa kuwala, ndipo chimagwiritsidwa ntchito kwambiri mu pulasitiki ndi zinthu zina zachilengedwe. Chimayamwa kuwala kwa ultraviolet komanso chimakhala chosasunthika.
Monga chothandizira kuyamwa kwa ultraviolet, chimapezeka ku PVC, polystyrene ndi Polyolefine ndi zina zotero. Kutalika kwa mafunde othamanga kwambiri ndi 280-340nm. Kugwiritsa ntchito konsekonse: 0.1-0.5% pa zinthu zoonda, 0.05-0.2% pa zinthu zokhuthala.
