Chovala chamvula cha TPU

TPU ili ndi mphamvu yokoka kwambiri, mphamvu yokoka kwambiri, kulimba komanso mphamvu zoletsa kukalamba, ndipo ndi chinthu choteteza chilengedwe. Izi zikutanthauza kuti, TPU ndi mtundu wa chovala chamvula chomwe anthu ambiri amachikonda masiku ano. Kukana kuzizira kwambiri: TPU ili ndi kutentha kochepa kwagalasi, komwe kumasunga kusinthasintha kwabwino, kusinthasintha komanso zinthu zina zakuthupi pa -35 digiri Celsius.

Chiyambi

TPU ndi chidule cha Thermoplastic Urethane, chomwe chimatchedwa thermoplastic polyurethane elastomer mu Chitchaina. TPU ndi zinthu zopangidwa ndi polima zopangidwa kuchokera ku mamolekyu a diisocyanate monga diphenylmethane diisocyanate (MDI) kapena toluene diisocyanate (TDI) ndi large-molecule polyol ndi low-molecule polyol (chain extender), zomwe zimapangidwa polima pamodzi mu reaction.

TPU ili ndi mphamvu yokoka kwambiri, mphamvu yokoka kwambiri, kulimba komanso kukana kukalamba, ndipo ndi chinthu choteteza chilengedwe chokhwima. Izi zikutanthauza kuti, TPU ndi mtundu wa chovala chamvula chomwe anthu ambiri amachikonda masiku ano.

Zifukwa zosankhira zinthu za TPU

Chovala chamvula cha TPU ndi mtundu watsopano wa chovala chamvula choteteza chilengedwe, ndipo chitsanzo cha ntchito yake chimakhudza gawo laukadaulo la zinthu za chovala chamvula. Choyamba, zinthu za chovala chamvula zimapangidwa ndi zinthu zomwe zimatha kuwonongeka kwathunthu, kuti zisawononge chilengedwe chikatayidwa. Chovala chamvula chikagwiritsidwa ntchito ndipo chikufunika kutayidwa, chingathe kukwiriridwa m'nthaka. Patapita nthawi, zinthu za chovala chamvula zimawonongeka kwathunthu, ndipo mbewu zimatha kumera ndikukula m'nthaka kuti zipange zomera, zomwe sizimangothetsa vuto la chitetezo cha chilengedwe cha chovala chamvula, komanso zimakhudza kubzala mitengo ndi kubiriwira.
