Tekanyetso ea ho tiea bakeng sa li-elastomer tsa polyurethane tsa TPU-thermoplastic

Bothata baTPU (thermoplastic polyurethane elastomer)ke e 'ngoe ea litšobotsi tsa eona tsa bohlokoa tsa 'mele, e leng se khethollang bokhoni ba thepa ba ho hanela ho fetoha, ho ngoapa le ho ngoapa. Hangata ho thatafala ho lekanngoa ho sebelisoa teko ea ho thatafala ha Shore, e arotsoeng ka mefuta e 'meli e fapaneng: Shore A le Shore D, e sebelisetsoang ho lekanyaLisebelisoa tsa TPUka mefuta e fapaneng ea thatafalo.

Ho ya ka diphetho tsa dipatlisiso, mefuta ya thata ya TPU e ka tloha Shore 60A ho ya Shore 80D, e leng se dumellang TPU ho akaretsa mefuta ya thata ya rabara le polasetiki le ho boloka ho tenyetseha ho hoholo ho pholletsa le mefuta yohle ya thata. Phetoho ya thata e ka fihlellwa ka ho fetola karolo ya dikarolo tse bonolo le tse thata ka hara ketane ya dimolek'hule tsa TPU. Phetoho ya thata e ka ama dibopeho tse ding tsa TPU, tse kang ho eketsa thata ya TPU e lebisang keketsehong ya modulus ya ho tensile le matla a ho tabola, keketseho ya ho tiea le kgatello ya khatello, phokotso ya ho lelefala, keketseho ya bongata le tlhahiso ya mocheso o matla, le keketseho ya ho hanyetsa tikoloho.

Litšebelisong tse sebetsang,khetho ea thatafalo ea TPUe tla khethoa ho latela litlhoko tse itseng tsa ts'ebeliso. Mohlala, TPU e bonolo (e lekanngoang ke Shore A hardness tester) e loketse lihlahisoa tse hlokang ho ama ka bonolo le ho lelefala ho hoholo, ha TPU e thata (e lekanngoang ke Shore D hardness tester) e loketse lihlahisoa tse hlokang bokhoni bo phahameng ba ho jara mojaro le ho hanyetsa ho tsofala hantle.

Ho phaella moo, bahlahisi ba fapaneng ba ka ba le maemo a itseng a thata le litlhaloso tsa sehlahisoa, tseo hangata li hlalositsoeng ka botlalo libukeng tsa botekgeniki tsa sehlahisoa. Bakeng sa lintlha tse qaqileng, ka kopo sheba webosaete ea semmuso eaYantai Linghua New Materials Co., Ltd.

Ha ho kgethwa thepa ya TPU, ho phaella ho thatafalo, thepa e meng ya mmele, mekgwa ya ho e sebetsana, ho ikamahanya le maemo a tikoloho, le dintlha tsa ditjeo di hloka ho nahanelwa ho netefatsa hore thepa e kgethilweng e ka fihlela ditlhoko tsa tshebetso ya ditshebediso tse itseng.
