Aliphatic letoto la TPU
ka TPU
Li-TPU tsa Aliphatic ke mofuta o ikhethileng oa thermoplastic polyurethane e bonts'ang khanyetso e phahameng ea UV, e li etsang hore li tšoanelehe bakeng sa lits'ebetso tsa kantle moo ho amehang nako e telele ea khanya ea letsatsi.
Ho ea ka thepa ea lik'hemik'hale ea likarolo tsa disocyanate lipid, TPU e ka aroloa ka lihlopha tse nkhang hamonate le tsa aliphatic. Monko o monate ke TPU e tloaelehileng ka ho fetisisa eo re e sebelisang (e sa hanyetsane le phello e mosehla kapa e mosehla e futsanehile, eseng boemo ba lijo), aliphatic hangata ke ho etsa lihlahisoa tse ngata tse phahameng. Mehlala e kenyelletsa lisebelisoa tsa bongaka, lisebelisoa tse hlokang ho hanyetsa yellowing ka ho sa feleng, joalo-joalo.
Aliphatic e boetse e arotsoe ka polyester / polyether.
Classification of yellowing resistance: Ka kakaretso e bapisoa le karete e putsoa, e arotsoe ka maemo a 1-5. Ka mor'a teko ea ho hanyetsa matheba a mosehla joalo ka Suntest, QUV kapa tlhahlobo e 'ngoe ea ho pepeseha ha letsatsi, bapisa phetoho ea' mala oa sampole pele le ka mor'a tlhahlobo, kereiti e ntle ka ho fetisisa ke 5, e bolelang hore ha e le hantle ha ho na phetoho ea mebala. 3 Tse latelang ke 'mala o hlakileng. Ka kakaretso, 4-5, ke hore, ho fifala hanyenyane, e kopane le lits'ebetso tse ngata tsa TPU. Haeba u sa hloke ho feto-fetoha ha mebala ho hang, ka kakaretso u hloka ho sebelisa aliphatic TPU, ke hore, TPU e bitsoang non-yellowing TPU, substrate ha se MDI, hangata HDI kapa H12MDI, joalo-joalo, le tlhahlobo ea UV ea nako e telele. e ke ke ea fetoha.
