ʻAʻole melemele TPU kiʻiʻoniʻoni me ka PET kūikawā kūikawā no ka mea PPF Lubrizol

Kumu waiwai

Hoʻohui: ʻO ka mea nui o ka kiʻi ʻoniʻoni ʻole o TPU he thermoplastic polyurethane elastomer, i hana ʻia e ka polymerization reaction o nā molekole diisocyanate e like me ka diphenylmethane diisocyanate a i ʻole toluene diisocyanate a me nā polyols macromolecular a me nā polyols haʻahaʻa.

Nā waiwai: Ma waena o ka lāʻau a me ka plastic, me ke kiʻekiʻe kiʻekiʻe, kiʻekiʻe kiʻekiʻe, ikaika a me nā mea ʻē aʻe

Ka pono noi

E pale i ka pena kaʻa: ua hoʻokaʻawale ʻia ka pena kaʻa mai ke kaiapuni o waho, e pale aku i ka hoʻoheheʻe ʻana o ka ea, ka wai ʻawaʻawa, a me nā mea ʻē aʻe, i ke kālepa kaʻa lua, hiki iā ia ke pale pono i ka pena kumu o ke kaʻa a hoʻomaikaʻi i ka waiwai o ke kaʻa.

Hana maʻalahi: Me ka maʻalahi a me ka stretchability maikaʻi, hiki iā ia ke hoʻopili pono i ka ʻili curved o ke kaʻa, inā ʻo ia ka mokulele o ke kino a i ʻole ka ʻāpana me ka arc nui, hiki iā ia ke hoʻokō paʻa, maʻalahi ke kūkulu ʻana, ikaika operability, a hōʻemi i nā pilikia e like me nā ʻōpū a me nā ʻāpana i ke kaʻina hana.

ʻO ke olakino kaiapuni: ʻO ka hoʻohana ʻana i nā mea pili i ke kaiapuni, ʻaʻohe mea ʻawaʻawa a me ka ʻono ʻole, pili i ke kaiapuni, i ka hana ʻana a me ka hoʻohana ʻana i ke kaʻina hana ʻaʻole ia e hōʻeha i ke kino kanaka a me ke kaiapuni.
