Cholimbitsa Chopepuka-944 CAS 70624-18-9
Cholimbitsa kuwala cha UV-944 chili ndi mphamvu yolimbana ndi kutulutsa zinthu, makamaka yoyenera zinthu zopyapyala, monga ulusi ndi mafilimu; Chingathenso kukulitsa mphamvu yolimbana ndi kutentha kwa mpweya wa zinthuzo. Cholimbitsa kuwala cha HS-944 ndi tinthu tating'onoting'ono toyera kapena tachikasu topepuka, malo osungunuka 100-135°C, kulemera kwa mamolekyulu 2000-3100, chokhala ndi mphamvu yogwirizana bwino, cholimbana ndi kutulutsa zinthu komanso chosasinthasintha. Popeza UV-944 ndi cholimbitsa kwambiri cha mamolekyulu, ndipo molekyuluyo ili ndi methylate yambiri yokha, imakhala yokhazikika ikapatsidwa mpweya wotentha.

Light Stabilizer-944 imagwiritsidwa ntchito mu filimu ya polyethylene yotsika kwambiri, ulusi wa polypropylene, tepi ya polypropylene, filimu ya EVA, ABS, polystyrene ndi ma phukusi azakudya. Light stabilizer HS-944 ndi ya hindered amine light stabilizer.
1. Mphamvu yabwino kwambiri yokhazikika pa kuwala: UV-944 imatha kuteteza bwino zinthu za polima ku kuwala kwa ultraviolet ndi kuwonongeka kwa kuwala ndi kutentha komwe kumachitika chifukwa cha kukalamba kwa kutentha kwa nthawi yayitali. Mphamvu yake yokhazikika pa kuwala imaposa kwambiri ya zotengera za ultraviolet ndi zokhazikika zomwe zili ndi nickel, makamaka m'makina a utoto komwe zotsatira zake zimakhala zoonekeratu.
2. Kugwirizana bwino ndi magwiridwe antchito: Ndi chinthu chachikasu chopepuka chowonekera bwino komanso chosasinthasintha kwambiri. Chimagwirizana bwino ndi zinthu zosiyanasiyana za polima monga PP, LDPE, HDPE, ndi PVC. Chimatha kufalikira mosavuta mu matrix ya polima popanda kusokoneza mawonekedwe ndi mtundu wa resin, ndipo chili ndi magwiridwe antchito abwino kwambiri.
3. Kugwiritsa ntchito mosiyanasiyana komanso kotetezeka komanso kodalirika: UV-944 ndi yoyenera mitundu yosiyanasiyana ya zinthu monga mafilimu, ulusi, ndi zinthu zokhuthala, ndipo ingagwiritsidwe ntchito pa ma polima angapo kuphatikiza ma polyolefin, ma polyurethane, ndi ma polyamides. Pakadali pano, yavomerezedwa ndi FDA ndipo ingagwiritsidwe ntchito pokhudzana ndi chakudya, kusonyeza kuti ndi yotetezeka kwambiri.
25kg/ng'oma kapena malinga ndi zomwe makasitomala akufuna.
