TPU-rauemi - whakamahia e te me mo te aha?

Pea e kore e taea e ki te ohorere i te kīanga rite TPU-rauemi kahore tetahi i tenei ra. He aha te mea te reira, Heoi, e mohio e kore katoa. Kei hea te whakamahia ai? He aha ngā āhuatanga e? Me pēhea te ki te wehewehe i te polyurethane rewarau i werohia? Ahakoa nga ritenga kitea, tawhā whakahaere me ngā āhuatanga kiritaki o ratou tino rerekē.

TPU-rauemi - he aha te mea te reira?

Na ake. TPU-rauemi - he aha te mea te reira? He aha nga tohu e tūturu i roto i reira? I roto i te meka, he mea ohie ki te wehewehe. Ko te rauemi tuatahi kua he matatu iti wäriu, tuku te whakamahi o ngā tuhinga i hanga i reira, kia rite ki kekeno. Tuarua, ka taea te hangarua TPU, e whakaora i runga i te feedstock. A toru, i roto i te ngaro o te rauemi whakakōkī rawa. Fourthly, Kei te āhuatanga i reira e te ora ratonga roa. I tua atu, he ātete ki te abrasion me te mahi tauhohenga wai o microorganisms te rauemi.

I roto i te parau tumu, enei kounga tūturu me polyurethanes whiwhi e te tikanga tikanga. Heoi, anake te TPU ahei tukatuka i runga i taputapu hangaia mō te hanga o kirihou mau - mīhini, ngā pūrere me ngā rārangi, ka karanga i werohia mīhini niao.

A, no te tīmata i te reira?

Na inaianei he moka o te aamu. A, no te puta reira TPU-rauemi? He aha e enei take awe tona ahua? tīmata te reira i katoa, mea hītori, rite wawe rite 1865. Company whai wāhi i roto i te hanga o nga poro, i hanga he fanongonongo rerekē. Ko te tangata kua whiwhi ki rauemi e whakakapi i rei, kua whakaaria mai tekau mano US tara. I roto i te 1869, ua faaoti Dzhon Hayat ki te whakamahi i nitrocellulose. whakahaere ia ki te whakatutuki i te kounga pai, me ngā āhuatanga, i muri i nei faaoti e ia ki te whakau i tona ake kamupene. Mai i timata taua taime te whanaketanga tere o te werohia mīhini niao me ngā rauemi, e hangaia ratou. Ki te rā, kua tutuki te ahumahi tiketike maere.

hanga o te TPU

He aha te mea te tukanga ahumahi? TPU-rauemi - he aha te mea te reira i roto i te hanga? Kia tīmata a ki te rauemi raw. Hoki te hanga o te TPU hiahiatia granules whiwhi tali mua wae polyurethane. O te akoranga, tuatahi riro ratou āhuatanga e tukua te rauemi ki te synthesize. Ko te moka mīhini werohia niao takiwā ki enei taua granules. I tua atu e whangai ratou e te tīwiri i roto i te rohe whakawera. I muri iho, e taea te patia i te papatipu kirihou ki te pokepokea ai pressurized (i roto i te hanga o ngā wāhanga uaua) ranei extruded, i.e. extruded i roto i te pupuha - whakatuwhera i te whirihoranga ngā (mo te hanga o nga wahi ohie, pērā i rakau, takai, rau).

painga

I roto i te poto, te huinga o ngā āhuatanga matū o TPU tahi me tikanga o ratou tukatuka taea ki te whiwhi rauemi ki te tawhā tinana nehenehe. Ko tētahi o te matua, hei tauira, he ātete wera tiketike. Hoki te nuinga o ngā hua i hanga i TPU, Initial pāmahana tamarûraa ko 120-140 degrees. I roto i tenei take, i hū te rauemi tino ora katoa o ona tawhā. Ahakoa kore e taea te whakahokia mai polyurethanes noa i muri taua pāmahana.

Kua kē matou whakahuatia ano hoki te taea o hangaruatanga te rauemi. wahi taea mongamonga a tonoa ana e ia ki muri.

painga nui ko te ātete tiketike ki te kakahu. Ko te kupu, Ka taea e te hua te mahi hei tiaki pai. Kei te whai wāhi hoki rauemi ātete ki te UV radiation. I roto i te whānui, i enei painga katoa hanga reira taea ki te tiki hua pai, e whai huru maitatai faahiahia. Hanga o tenei rauemi, hei tauira, e hipokina hoki Samsung, Nokia me ētahi atu waea. Ēnei hua i te rongonui nui i tenei ra. Heoi, he aha te hua e whiriwhiri koe, kia mohio ki te noho oaoa.
