Nā Mea Maka TPU kiʻekiʻe no nā kiʻiʻoniʻoni TPU extrusion

Nā Kikoʻī a me nā Noi ʻOihanaNā mea maka TPUno nā kiʻiʻoniʻoni ua hoʻohana nui ʻia ma nā ʻoihana like ʻole ma muli o kā lākou hana maikaʻi loa. Eia kahi hoʻolauna kikoʻī ma ka ʻōlelo Pelekania: 1. ʻIke Kumu ʻO TPU ka pōkole o ka thermoplastic polyurethane, i ʻike ʻia hoʻi ʻo thermoplastic polyurethane elastomer. Hana pinepine ʻia nā mea maka TPU no nā kiʻiʻoniʻoni ma ka polymerizing ʻekolu mau mea maka nui: polyols, diisocyanates, a me nā mea hoʻolōʻihi kaulahao. Hāʻawi nā Polyols i ka ʻāpana palupalu o TPU, e hāʻawi ana iā ia me ka maʻalahi a me ka elasticity. Hoʻopili ʻo Diisocyanates me nā polyols e hana i ka ʻāpana paʻakikī, kahi e hāʻawi ai i ka ikaika a me ke kūpaʻa o TPU. Hoʻohana ʻia nā mea hoʻolōʻihi kaulahao e hoʻonui i ke kaumaha molekala a hoʻomaikaʻi i nā waiwai mechanical o TPU. 2. Kaʻina Hana Hana Hana ʻia nā kiʻiʻoniʻoni TPU mai nā mea granular TPU ma o nā kaʻina hana e like me ka calendering, casting, blowing, a me ka coating. I waena o lākou, ʻo ke kaʻina hana hoʻoheheʻe - extrusion kahi ʻano maʻamau. ʻO ka mea mua, ua hui pū ʻia ka polyurethane me nā mea hoʻohui like ʻole, e like me nā plasticizers e hoʻonui i ka maʻalahi, nā mea hoʻopaʻa e hoʻomaikaʻi i ka pale wela a me ka mālamalama, a me nā pigments no ke kala ʻana. A laila, ua hoʻomehana ʻia a hoʻoheheʻe ʻia, a laila ua koi ʻia ma o kahi make e hana i kahi kiʻiʻoniʻoni hoʻomau, kahi i hoʻomaʻalili ʻia a ʻōwili ʻia i loko o kahi ʻōwili. He mea koʻikoʻi ke kaʻina hoʻomaʻalili no ka mea e pili ana i ka crystallization a me ke kuhikuhi ʻana o nā molekala TPU, no laila e hoʻohuli i nā waiwai hope loa o ke kiʻiʻoniʻoni. 3. Nā ʻano hana 3.1 Nā waiwai kino Loaʻa i nā kiʻiʻoniʻoni TPU ka maʻalahi a me ka elasticity maikaʻi loa, 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, kahi kūpono no nā hiʻohiʻona e pono ai ke kulou pinepine a me ka wili. No ka laʻana, i ka hana ʻana o nā mea uila maʻalahi, hiki i nā kiʻiʻoniʻoni TPU ke kūlike me nā ʻili piʻo o nā mea hana. I ka manawa like, loaʻa iā ia ka ikaika tensile kiʻekiʻe a me ka ikaika pale haehae, hiki ke pale pono i ka hopena a me ka hōʻino o waho. ʻO kēia ka mea e kūpono ai nā kiʻiʻoniʻoni TPU no nā noi i loko o ka pahu pale, kahi e pono ai lākou e kū i ka lawelawe ʻino. 3.2 Nā waiwai kemika Loaʻa i nā kiʻiʻoniʻoni TPU ke kūpaʻa maikaʻi i ka palaho kemika, a he ʻano hoʻomanawanui i nā waikawa maʻamau, alkalis, solvents, etc., a ʻaʻole maʻalahi ke palaho. ʻO ke ʻano kūikawā, ʻo ke kūpaʻa hydrolysis o nā kiʻiʻoniʻoni TPU ʻano polyether e hiki ai iā lākou ke mālama i ka hana paʻa i nā wahi wai. ʻO kēia waiwai e kūpono ai lākou no ka hoʻohana ʻana i nā noi e like me nā uhi wai a me nā membrane wai ʻole. 3.3 Ke Kūʻē ʻana i ke AniauNā kiʻiʻoniʻoni TPUhiki ke mālama i ka hana paʻa i nā ʻano mahana like ʻole. ʻAʻole maʻalahi lākou e lilo i paʻakikī a palupalu i nā ʻano mahana haʻahaʻa, ʻaʻole hoʻi maʻalahi lākou e palupalu a hoʻololi i nā ʻano mahana kiʻekiʻe. Loaʻa iā lākou kahi hiki ke pale aku i nā kukuna ultraviolet, a ʻaʻole maʻalahi ke ʻelemakule a mae i lalo o ka ʻike ʻana o ka mālamalama lōʻihi. ʻO kēia ka mea e kūpono ai nā kiʻiʻoniʻoni TPU no nā noi waho, e like me ke kāhiko waho o ke kaʻa a me nā uhi lako waho. 4. Nā ʻAno Hana Hana Nui ʻO nā ʻano hana hana nui oNā kiʻiʻoniʻoni TPUe komo pū me ka hoʻoheheʻe ʻana i ka puhi, ka hoʻolei ʻana, a me ke kalena. Ma o ka hoʻoheheʻe ʻana i ka puhi, hiki ke hana ʻia nā kiʻiʻoniʻoni TPU me nā mānoanoa a me nā laulā like ʻole ma ka hoʻopiha ʻana i kahi paipu TPU i hoʻoheheʻe ʻia. ʻO ka hoʻolei ʻana e pili ana i ka ninini ʻana i kahi ʻano TPU wai ma luna o kahi pālahalaha a ʻae iā ia e paʻa. Hoʻohana ka kalena i nā wili e kaomi a hoʻoponopono i ka TPU i loko o kahi kiʻiʻoniʻoni o ka mānoanoa i makemake ʻia. Hiki i kēia mau ʻano hana ke hana i nā kiʻiʻoniʻoni TPU o nā mānoanoa like ʻole, nā laulā, a me nā kala e hoʻokō i nā pono o nā hiʻohiʻona noi like ʻole. No ka laʻana, hoʻohana pinepine ʻia nā kiʻiʻoniʻoni TPU lahilahi a moakaka i loko o ka hoʻopili ʻana, ʻoiai hiki ke hoʻohana ʻia nā kiʻiʻoniʻoni mānoanoa a me nā kala i nā noi hoʻonaninani. 5. Nā Kahua Hoʻohana Hiki ke hoʻohui ʻia nā kiʻiʻoniʻoni TPU me nā ʻano lole like ʻole e hana i nā lole kāmaʻa - luna me nā hana wai ʻole a me ka hanu, a i ʻole nā ​​​​lole hoʻonaninani, i hoʻohana nui ʻia i nā lole maʻamau, nā lole sunscreen, nā lole komo, nā ʻaʻahu ua, nā pale makani, nā pālule T, nā lole haʻuki a me nā lole ʻē aʻe. Ma ke kahua lapaʻau,Nā kiʻiʻoniʻoni TPUhoʻohana ʻia i nā noi e like me nā ʻaʻahu ʻeha a me nā uhi ʻana i nā mea lapaʻau ma muli o ko lākou biocompatibility. Eia kekahi, ua hoʻohana nui ʻia ʻo TPU i nā mea kāmaʻa, nā mea pāʻani inflatable, nā lako haʻuki, nā mea noho kaʻa, nā umbrellas, nā ʻeke lima a me nā ʻoihana ʻē aʻe. No ka laʻana, i nā lako haʻuki, hoʻohana ʻia nā kiʻiʻoniʻoni TPU e hana i nā pads pale a me nā grips, e hāʻawi ana i ka ʻoluʻolu a me ke kūpaʻa.
