Nā Mea Kiʻi TPU Kiʻekiʻe no nā kiʻiʻoniʻoni TPU extrusion

Nā kikoʻī a me nā noi ʻoihanaTPU mea makano ka mea, hoʻohana nui ʻia nā kiʻiʻoniʻoni ma nā ʻoihana like ʻole ma muli o kā lākou hana maikaʻi loa. ʻO kēia ka ʻōlelo kikoʻī o ka ʻōlelo Pelekane: 1. ʻIke kumu ʻo TPU ka pōkole o ka polyurethane thermoplastic, ʻike ʻia hoʻi ʻo thermoplastic polyurethane elastomer. Hana ʻia nā mea maka TPU no nā kiʻiʻoniʻoni ma o ka polymerizing ʻekolu mau kumu kumu: polyols, diisocyanates, a me nā kaulahao. Hāʻawi nā Polyols i ka ʻāpana palupalu o TPU, hāʻawi iā ia me ka maʻalahi a me ka elasticity. Hoʻopili ʻo Diisocyanates me nā polyols e hana i ka ʻāpana paʻakikī, e kōkua ana i ka ikaika a me ka lōʻihi o TPU. Hoʻohana ʻia nā mea hoʻonui kaulahao e hoʻonui i ke kaumaha molecular a hoʻomaikaʻi i nā waiwai mechanical o TPU. 2. Ka Hana Hana Hana ʻia nā kiʻiʻoniʻoni TPU mai nā mea granular TPU ma o nā kaʻina hana e like me ka calendering, ka hoʻolei ʻana, ka puhi ʻana, a me ka uhi ʻana. I waena o lākou, he hana maʻamau ka hoʻoheheʻe - extrusion. ʻO ka mea mua, ua hui pū ʻia ka polyurethane me nā mea hoʻohui like ʻole, e like me nā plasticizers e hoʻomaikaʻi i ka maʻalahi, stabilizers e hoʻomaikaʻi i ka wela a me ka pale māmā, a me nā puaʻa no ke kala. A laila, hoʻomehana ʻia a hoʻoheheʻe ʻia a hoʻoheheʻe ʻia i loko o kahi die e hana i kahi kiʻiʻoniʻoni mau, a hoʻomaʻalili ʻia a ʻeha i loko o kahi ʻōwili. He mea koʻikoʻi ke kaʻina hana hoʻoluʻu no ka mea e pili ana i ka crystallization a me ka orientation o nā molekala TPU, no laila e hoʻopili ai i nā waiwai hope o ke kiʻiʻoniʻoni. 3. Nā Hana Hana 3.1 Nā Pono Kino ʻO nā kiʻiʻoniʻoni TPU loaʻa ka maʻalahi a me ka elasticity, a hiki ke hoʻolōʻihi ʻia a hoʻololi ʻia i kekahi ʻano, a hiki ke hoʻi i ko lākou ʻano kumu me ka ʻole o ka deformation, i kūpono i nā hiʻohiʻona e pono ai ke kulou pinepine a me ka wili. No ka laʻana, i ka hana ʻana i nā mea uila maʻalahi, hiki i nā kiʻiʻoniʻoni TPU ke hoʻohālikelike i nā ʻaoʻao curved o nā hāmeʻa. I ka manawa like, loaʻa iā ia ka ikaika tensile kiʻekiʻe a me ka waimaka - ikaika kū'ē, hiki ke pale pono i ka hopena o waho a me ka pōʻino. Hana kēia i nā kiʻiʻoniʻoni TPU i kūpono no nā noi i loko o ka pale pale, kahi e pono ai lākou e pale i ka hana ʻino. 3.2 Mea Kinohi Loaʻa i nā kiʻiʻoniʻoni TPU maikaʻi ke kūʻē i ka corrosion kemika, a loaʻa kekahi ʻae ʻana i nā waikawa maʻamau, alkalis, solvents, etc., a ʻaʻole maʻalahi ke corroded. ʻO ka mea kūikawā, hiki i ka hydrolysis resistance o polyether - type TPU films e hiki ai iā lākou ke hoʻomau i ka hana paʻa i ka wai - waiwai waiwai. Hana kēia waiwai iā lākou i mea kūpono no ka hoʻohana ʻana i nā noi e like me ka uhi ʻana i lalo o ka wai a me nā membrane wai. 3.3 Kū'ē i ka LewaNā kiʻiʻoniʻoni TPUhiki ke mālama i ka hana paʻa i nā ʻano wela like ʻole. ʻAʻole maʻalahi lākou e lilo i mea paʻakikī a palupalu i nā wahi haʻahaʻa haʻahaʻa, ʻaʻole maʻalahi lākou e palupalu a hoʻololi i nā kaiapuni kiʻekiʻe. Loaʻa iā lākou kekahi hiki ke pale aku i nā kukuna ultraviolet, a ʻaʻole maʻalahi ke ʻelemakule a mae ma lalo o ka hoʻomālamalama kukui lōʻihi. Hana kēia i nā kiʻiʻoniʻoni TPU i kūpono no nā noi waho, e like me ka ʻokiʻoki o waho a me nā uhi kīwaha o waho. 4. Nā Hana Hana Nui ʻO nāʻano hana nui oNā kiʻiʻoniʻoni TPUe hoʻokomo i ka puhi - hoʻoheheʻe, hoʻolei ʻana, a me ka calendering. Ma o ka puhi - hoʻoheheʻe ʻia, hiki ke hana ʻia nā kiʻiʻoniʻoni TPU me nā mānoanoa like ʻole a me nā laula ma o ka hoʻoulu ʻana i kahi paipu TPU hoʻoheheʻe ʻia. ʻO ka hoʻolei ʻana, ʻo ia ka ninini ʻana i kahi hoʻoheheʻe TPU wai ma luna o kahi ʻili palahalaha a ʻae iā ia e paʻa. Hoʻohana ʻo Calendering i nā wili e kaomi a hoʻohua i ka TPU i kiʻiʻoniʻoni o ka mānoanoa i makemake ʻia. Hiki i kēia mau ala ke hana i nā kiʻiʻoniʻoni TPU o nā mānoanoa like ʻole, ākea, a me nā kala e hoʻokō i nā pono o nā hiʻohiʻona noiʻi like ʻole. No ka laʻana, hoʻohana pinepine ʻia nā kiʻiʻoniʻoni TPU lahilahi a aniani i ka hoʻopili ʻana, ʻoiai hiki ke hoʻohana ʻia nā kiʻiʻoniʻoni ʻoi aku ka mānoanoa a me ke kala i nā noi hoʻonaninani. 5. Nā Papa Hana Hiki ke hoʻohuiʻia nā kiʻiʻoniʻoni TPU me nā lole likeʻole e hana i nā kāmaʻa - nā lole luna me nā hana waiʻole a me ka hanu, a iʻole nā ​​mea hoʻonani, i hoʻohana nuiʻia i nā lole maʻamau, nā lole pale lā, nā lole komo, nā ua, nā makani makani, nā T - nā pālule, nā lole haʻuki a me nā lole'ē aʻe. Ma ke kahua lapaʻau,Nā kiʻiʻoniʻoni TPUhoʻohana ʻia i nā noi e like me nā ʻaʻahu ʻeha a me nā mea hoʻolale kino ma muli o ko lākou biocompatibility. Eia kekahi, ua hoʻohana nui ʻia ʻo TPU i nā mea kāmaʻa, nā mea pāʻani inflatable, nā mea haʻuki, nā mea noho kaʻa, nā umbrellas, nā ʻeke, nā ʻeke lima a me nā kahua ʻē aʻe. No ka laʻana, i nā mea haʻuki, hoʻohana ʻia nā kiʻiʻoniʻoni TPU e hana i nā pale pale a me nā paʻa, e hāʻawi ana i ka hōʻoluʻolu a me ka lōʻihi.
