Pulasitiki TPU zopangira

Tanthauzo: TPU ndi mzere wa block copolymer wopangidwa kuchokera ku diisocyanate yomwe ili ndi gulu logwira ntchito la NCO ndi polyether yomwe ili ndi gulu la OH, polyester polyol ndi chain extender, zomwe zimatuluka ndikusakanikirana.
Makhalidwe: TPU imagwirizanitsa mawonekedwe a mphira ndi pulasitiki, ndi kusungunuka kwakukulu, mphamvu zambiri, kukana kuvala kwambiri, kukana mafuta, kukana madzi, kukana kutentha, kukana kukalamba ndi ubwino wina.
mtundu
Malingana ndi mapangidwe a gawo lofewa, likhoza kugawidwa mu mtundu wa polyester, mtundu wa polyether ndi mtundu wa butadiene, womwe uli ndi gulu la ester, gulu la ether kapena gulu la butene motsatira. PolyesterTPUali ndi mphamvu zamakina abwino, kukana kuvala komanso kukana mafuta.Polyether TPUali bwino hydrolysis kukana, otsika kutentha kukana ndi kusinthasintha.
Malinga ndi mawonekedwe a gawo lolimba, amatha kugawidwa mumtundu wa aminoester ndi aminoester urea, omwe amachokera ku diol chain extender kapena diamine chain extender, motsatana.
Malinga ngati pali crosslinking: akhoza kugawidwa mu thermoplastic koyera ndi theka-thermoplastic. Yoyamba ndi yoyera liniya dongosolo popanda crosslinking. Chotsatiracho ndi chomangira chophatikizika chokhala ndi mawonekedwe ochepa a urea.
Malinga ndi kugwiritsa ntchito zinthu zomalizidwa, zitha kugawidwa m'magawo apadera (magawo osiyanasiyana amakina), mapaipi (ma jekete, mbiri ya ndodo) ndi mafilimu (mapepala, mapepala), komanso zomatira, zokutira ndi ulusi.
Ukadaulo wopanga
Kuchuluka kwa polymerization: kungathenso kugawidwa mu njira ya pre-polymerization ndi njira imodzi yokha malinga ndi zomwe zisanachitikepo. Njira ya prepolymerization ndikuchita diisocyanate ndi macromolecule diol kwa nthawi inayake musanawonjezere unyolo kuti mupange TPU. Njira imodzi ndiyo kusakaniza macromolecular diol, diisocyanate ndi chain extender nthawi imodzi kuti apange TPU.
Anakonza polymerization: ndi diisocyanate choyamba kusungunuka mu zosungunulira, ndiyeno macromolecule diol ndi anawonjezera kuchitapo kwa nthawi inayake, ndipo potsiriza unyolo extender ndi anawonjezera kubala.TPU.
Malo ogwiritsira ntchito
Munda wazinthu za nsapato: Chifukwa TPU ili ndi kukhazikika bwino komanso kukana kuvala, imatha kupititsa patsogolo chitonthozo ndi kulimba kwa nsapato, ndipo nthawi zambiri imagwiritsidwa ntchito pazokha, zokongoletsera zapamwamba, thumba la mpweya, khushoni ya mpweya ndi mbali zina za nsapato zamasewera ndi nsapato wamba.
Malo azachipatala: TPU ili ndi biocompatibility yabwino kwambiri, yopanda poizoni, yopanda matupi awo sagwirizana ndi zinthu zina, imatha kugwiritsidwa ntchito kupanga ma catheter azachipatala, zikwama zachipatala, ziwalo zopangira, zida zolimbitsa thupi ndi zina zotero.
Munda wamagalimoto: TPU angagwiritsidwe ntchito kupanga zida mipando galimoto, mapanelo zida, chivundikiro chiwongolero, zisindikizo, payipi mafuta, etc., kukwaniritsa zofunika chitonthozo, kuvala kukana ndi kukana nyengo ya mkati magalimoto, komanso zofunika kukana mafuta ndi kutentha kukana kwa chipinda injini galimoto.
Magawo amagetsi ndi magetsi: TPU ili ndi kukana kwabwino kovala, kukana kukanda komanso kusinthasintha, ndipo ingagwiritsidwe ntchito kupanga waya ndi chingwe sheath, foni yam'manja, chivundikiro choteteza makompyuta, filimu ya kiyibodi ndi zina zotero.
Munda wa mafakitale: TPU ingagwiritsidwe ntchito kupanga zida zosiyanasiyana zamakina, malamba otumizira, zisindikizo, mapaipi, mapepala, ndi zina zotero, zimatha kupirira kupanikizika kwakukulu ndi kukangana, pokhala ndi kukana kwa dzimbiri komanso kukana nyengo.
Munda wa zinthu zamasewera: zomwe zimagwiritsidwa ntchito kwambiri popanga zida zamasewera, monga basketball, mpira, volebo ndi liner ena, komanso skis, skateboards, ma cushions okhala ndi njinga, ndi zina zambiri, zimatha kupereka kusinthasintha kwabwino komanso chitonthozo, kusintha magwiridwe antchito.

Malingaliro a kampani Yantai Linghua New Material Co., Ltd. ndi wogulitsa TPU wotchuka ku China.
