Mafotokozedwe Akatundu
Thermoplastic polyester elastomer (TPEE) ndi mtundu wa chipika copolymer, Zimaphatikizapo crystalline poliyesitala gawo lolimba lomwe lili ndi malo osungunuka kwambiri komanso kuuma kwakukulu ndi gawo lofewa la amorphous polyether kapena polyester lomwe lili ndi kutentha kocheperako kwa galasi, limapangidwa kukhala magawo awiri. mawonekedwe a gawo, gawo lolimba la crystallization limakhudzanso kugwirizanitsa thupi ndi kukhazikika kwa mankhwala, gawo lofewa limakhudza polima amorphous ndi resilience. mafuta kukana kwa TPEE.Kuonjezera chiŵerengero cha zigawo zofewa akhoza kusintha elasticity ndi otsika kutentha kupatuka kwa TPEE.TPEE alinso ndi katundu wa softness ndi elasticity wa mphira, komanso rigidity wa thermoplastic ndi yosavuta processing.Kuuma kwa gombe lake ndi 63D.

Kusungirako ndi zoyendera
Phukusi:
Njira ziwiri za paketi:
1. Imadzaza 900/1000KG pa thumba limodzi ndi akalowa mkati mwazojambula za aluminiyamu, nsalu yakunja ya PE yoluka.
2. Imadzaza 25KG pachikwama chilichonse chokhala ndi zolembera zamkati za aluminiyamu, chinsalu chakunja cha pepala la kraft.
Mayendedwe:Chogulitsacho chisamawoneke kuti chinyowe kapena chinyezi panthawi yamayendedwe, ndikuchisunga chouma, chaukhondo, chokwanira komanso chopanda kuipitsa.
Posungira:Zogulitsazo zimasungidwa m'nyumba yosungiramo zinthu zaukhondo, zozizirira, zowuma komanso zolowera mpweya wabwino kutali ndi komwe kumayaka moto.Ngati mankhwalawa apezeka kuti akunyowa chifukwa chamvula kapena ndi chinyezi chambiri mumlengalenga, Atha kugwiritsidwa ntchito patatha maola atatu ataumitsa kutentha kwa 80-110 ℃.
