Zipangizo zopangira za pulasitiki za TPU

Tanthauzo: TPU ndi copolymer yozungulira yopangidwa kuchokera ku diisocyanate yokhala ndi gulu la ntchito la NCO ndi polyether yokhala ndi gulu la ntchito la OH, polyester polyol ndi chain extender, zomwe zimatulutsidwa ndikusakanizidwa.
Makhalidwe: TPU imagwirizanitsa makhalidwe a rabara ndi pulasitiki, yokhala ndi kusinthasintha kwakukulu, mphamvu zambiri, kukana kuvala kwambiri, kukana mafuta, kukana madzi, kukana kutentha kochepa, kukana ukalamba ndi zabwino zina.
konza
Malinga ndi kapangidwe ka gawo lofewa, lingagawidwe m'magulu awiri: mtundu wa polyester, mtundu wa polyether ndi mtundu wa butadiene, womwe uli ndi gulu la ester, gulu la ether kapena gulu la butene motsatana.TPUIli ndi mphamvu yabwino yamakina, kukana kukalamba komanso kukana mafuta.Polyether TPUali ndi kukana bwino kwa hydrolysis, kukana kutentha kochepa komanso kusinthasintha.
Malinga ndi kapangidwe ka gawo lolimba, lingagawidwe m'magulu awiri: mtundu wa aminoester ndi mtundu wa aminoester urea, womwe umapezeka kuchokera ku diol chain extender kapena diamine chain extender, motsatana.
Malinga ndi ngati pali kulumikiza: kungagawidwe m'magulu awiri: thermoplastic yoyera ndi semi-thermoplastic. Yoyamba ndi kapangidwe koyera kopanda kulumikiza. Yomalizayi ndi chomangira cholumikizidwa chokhala ndi urea wochepa.
Malinga ndi momwe zinthu zomalizidwa zimagwiritsidwira ntchito, zitha kugawidwa m'magawo opangidwa mwapadera (zigawo zosiyanasiyana zamakina), mapaipi (majekete, ma profiles a ndodo) ndi mafilimu (mapepala, mapepala), komanso zomatira, zokutira ndi ulusi.
Ukadaulo wopanga
Kupoletsa kwakukulu: kungagawidwenso m'njira ya pre-polymerization ndi njira imodzi kutengera ngati pali pre-reaction. Njira ya prepolymerization ndikuchita diisocyanate ndi macromolecule diol kwa nthawi inayake musanawonjezere chain extender kuti ipange TPU. Njira imodzi ndi kusakaniza macromolecular diol, diisocyanate ndi chain extender nthawi imodzi kuti ipange TPU.
Kupolima kwa yankho: diisocyanate imasungunuka kaye mu solvent, kenako macromolecule diol imawonjezedwa kuti igwire ntchito kwa nthawi inayake, ndipo pamapeto pake chowonjezera cha unyolo chimawonjezedwa kuti chipangeTPU.
Munda wofunsira
Nsapato: Popeza TPU ili ndi kusinthasintha kwabwino komanso kukana kuvala, imatha kupititsa patsogolo chitonthozo ndi kulimba kwa nsapato, ndipo nthawi zambiri imagwiritsidwa ntchito pa zokongoletsa pamwamba, thumba la mpweya, pilo ya mpweya ndi zina mwa nsapato zamasewera ndi nsapato wamba.
Munda wazachipatala: TPU ili ndi mgwirizano wabwino kwambiri ndi thupi, si poizoni, si yokhudzana ndi ziwengo ndi zina, ingagwiritsidwe ntchito popanga ma catheter azachipatala, matumba azachipatala, ziwalo zopanga, zida zolimbitsa thupi ndi zina zotero.
Malo Oyendetsera Magalimoto: TPU ingagwiritsidwe ntchito popanga mipando ya magalimoto, zida zoimbira, zophimba mawilo oyendetsera, zisindikizo, payipi yamafuta, ndi zina zotero, kuti ikwaniritse zofunikira kuti ikhale yomasuka, yolimba komanso yolimba mkati mwa magalimoto, komanso zofunikira kuti injini ya magalimoto isatenthe mafuta komanso kutentha kwambiri.
Magawo amagetsi ndi amagetsi: TPU ili ndi kukana kwabwino kwa kuwonongeka, kukana kukanda komanso kusinthasintha, ndipo ingagwiritsidwe ntchito kupanga waya ndi chingwe, chikwama cha foni yam'manja, chivundikiro choteteza kompyuta ya piritsi, filimu ya kiyibodi ndi zina zotero.
Munda wa mafakitale: TPU ingagwiritsidwe ntchito popanga zida zosiyanasiyana zamakanika, malamba onyamulira, zisindikizo, mapaipi, mapepala, ndi zina zotero, imatha kupirira kupsinjika kwakukulu ndi kukangana, pomwe ili ndi kukana bwino dzimbiri komanso kukana nyengo.
Munda wa zinthu zamasewera: zomwe zimagwiritsidwa ntchito kwambiri popanga zida zamasewera, monga basketball, mpira wamiyendo, volleyball ndi zina zoyendera mpira, komanso ma ski, ma skateboard, ma cushion a mipando ya njinga, ndi zina zotero, zimatha kupereka kusinthasintha kwabwino komanso chitonthozo, komanso kukonza magwiridwe antchito amasewera.

Yantai linghua new material co.,ltd. ndi kampani yotchuka yogulitsa zinthu za TPU ku China.
