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.
Light Stabilizer 770 ndi chida chothandiza kwambiri choteteza ma radicals kuti asawonongeke chifukwa cha kuwala kwa ultraviolet. Light Stabilizer 770 imagwiritsidwa ntchito kwambiri m'njira zosiyanasiyana kuphatikizapo polypropylene, polystyrene, polyurethanes, ABS, SAN, ASA, polyamides ndi polyacetals.
Light Stabilizer 622 ndi ya m'badwo watsopano wa polymeric Hindered Amine Light Stabilizer, yomwe ili ndi kukhazikika kwabwino kwambiri pakukonza kutentha. Imagwirizana bwino ndi utomoni, imasinthasintha bwino motsutsana ndi madzi komanso imakhala yosasinthasintha kwambiri komanso yosasuntha. Light stabilizer 622 ingagwiritsidwe ntchito pa PE.PP.
Polyester yosakhuta: 0.2-0.5wt% kutengera kulemera kwa polima
PVC yolimba: 0.2-0.5wt% kutengera kulemera kwa polima
PVC yopangidwa ndi pulasitiki: 0.1-0.3wt% kutengera kulemera kwa polima
Polyurethane: 0.2-1.0wt% kutengera kulemera kwa polima
Polyamide: 0.2-0.5wt% kutengera kulemera kwa polima
Chogulitsachi ndi chokhazikika cha histamine macromolecule light stabilizer. Popeza pali magulu ambiri azinthu zachilengedwe mu molekyulu yake, kukhazikika kwake kwa kuwala kumakhala kwakukulu kwambiri. Chifukwa cha kulemera kwake kwakukulu kwa mamolekyulu, mankhwalawa ali ndi kukana kutentha, kukhazikika, kusinthasintha kochepa komanso kuyanjana bwino kwa colophony. Chogulitsachi chingagwiritsidwe ntchito pa polyethylene yotsika kwambiri, polypropylene fiber ndi glue lamba, EVA ABS, polystyrene ndi phukusi la chakudya ndi zina zotero.
Amagwiritsidwa ntchito makamaka poyeretsa polyester, polyamide, polyacrylonitrile ulusi, filimu ya pulasitiki ndi njira zonse zosindikizira pulasitiki. Oyenera kupanga polima yayikulu kuphatikiza njira ya polymeric.
UV-571 ndi mankhwala amadzimadzi otchedwa benzotriazole UV absorbers omwe angagwiritsidwe ntchito popanga zokutira za PUR za thermoplastic ndi thovu lonse, PVC yolimba ya pulasitiki, PVB, PMMA, PVDC, EVOH, EVA, kuchiritsa kutentha kwambiri kwa polyester yosakhuta komanso zowonjezera za PA, PET, PUR ndi PP fiber spinning, latex, sera, zomatira, styrene homopolymer - ndi copolymers, elastomers ndi polyolefin.
LS-119 ndi imodzi mwa zolimbitsa kuwala kwa ultraviolet kolemera kwambiri komwe kumakhala ndi kukana kusuntha bwino komanso kusasinthasintha kochepa. Ndi antioxidant yothandiza yomwe imapereka kukhazikika kwa kutentha kwa nthawi yayitali kwa ma polyolefin ndi ma elastomer. LS-119 imagwira ntchito makamaka mu PP, PE, PVC, PU, PA, PET, PBT, PMMA, POM, LLDPE, LDPE, HDPE, polyolefin copolymers ndi zosakaniza ndi UV 531 mu PO.
Chogulitsachi ndi chothandiza kwambiri kuyamwa kuwala kwa UV, chomwe chimatha kuyamwa bwino kuwala kwa UV kwa kutalika kwa 290-400 nm, koma sichimayamwa kuwala kooneka, makamaka pazinthu zowala zowonekera.
Choyamwa UV chogwira ntchito bwino kwambiri cha PVC, PE, PP, ABS ndi ma polyester osakhuta
LS 783 ndi chisakanizo chogwirizana cha chokhazikika cha kuwala 944 ndi chokhazikika cha kuwala 622.Ndi chokhazikika chogwiritsa ntchito kuwala cholimba chomwe chimatha kuchotsedwa bwino, mpweya wochepa komanso utoto wochepa. LS 783 ndi yoyenera kwambiri mafilimu a LDPE, LLDPE, HDPE, matepi ndi magawo okhuthala komanso mafilimu a PP. Ndi chinthu chomwe chimasankhidwa kwambiri m'magawo okhuthala komwe kumafunika chilolezo chokhudzana ndi chakudya mwachindunji.
