1. Nā hiʻohiʻona
Loaʻa i nā mīkina lima TPE nā hiʻohiʻona o ka pale ʻana i ka wā kahiko, ka elasticity kiʻekiʻe a me ka pale ʻana i ka aila, a maʻalahi ke hana a hana;Loaʻa i nā mīkina lima CPE nā hiʻohiʻona o ke kumu kūʻai haʻahaʻa, palupalu a me ka laulā noi.
2. Palekana
Hiki i nā mīkina lima CPE ke hoʻopau maʻalahi i ke kinoea hydrogen chloride ma 50 ℃, he mea pōʻino i ke kino kanaka.ʻO ka hana a me ka hana hana e hoʻohaumia i ke kaiapuni, a he haʻahaʻa ka palekana;ʻO nā mīkina lima TPE kahi ʻano mea mālama kaiapuni, hiki ke hana hou a hoʻohana hou ʻia.ʻAʻole ia e hoʻokuʻu i nā mea ʻawaʻawa ma lalo o ka wela kiʻekiʻe, a ʻoi aku ka palekana no ka poʻe e hoʻohana.
Nā ʻokoʻa ma waena o TPE, CPE a me TPU:
ʻO nā mea waiwai nui o nā mīkina lima CPE ʻo LDPE, LLDPE, mLLDPE, etc.
ʻO ka Tpe-thermoplastic elastomer kahi mea hou me ka elasticity kiʻekiʻe, ka ikaika kiʻekiʻe a me ke kūpaʻa kiʻekiʻe o ka lāʻau.
ʻO TPU kahi thermoplastic polyurethane elastomer, hiki ke hoʻokaʻawale ʻia i TPE thermoplastic elastomer.
ʻOi aku ka maikaʻi o ke kūpaʻa a me ke kūpaʻa ʻana o ka TPU ma mua o ka TPE, ʻo ia ka mea ma muli o ka ʻokoʻa o ka ʻāpana molecular structure.Eia kekahi, ʻoi aku ka haʻahaʻa o ka microstructure a me nā waiwai o nā huila TPE ma mua o nā hui TPU.He hopena ko'iko'i ko ka multi-component o TPE i kāna hana springback.ʻOi loa no ka TPE me ka paʻakikī kiʻekiʻe, ʻo ka hapa nui o ka mea polypropylene e hoʻemi nui ʻia ka resilience o TPE, a hiki i nā huahana ke deformation ma lalo o ka hana mau o ka ikaika o waho.
Manaʻo lima: He kiʻekiʻe ke kūpaʻa ʻana o ka TPU, ka paʻa lima ikaika a me ka palupalu maikaʻi ʻole.
TPE: ma muli o ke ʻano kaulahao molecular maʻalahi o SEBS, ʻoluʻolu, ʻoluʻolu a maʻalahi ka mea
Ua like loa ka manao o CPE me ko TPE.ʻO ke kiʻiʻoniʻoni CPE i hana ʻia e ka embossing roller he ʻano maikaʻi a ʻoi aku ka mānoanoa.
Nā hiʻohiʻona:Loaʻa i nā mīkina lima TPE nā hiʻohiʻona o ka pale ʻana i ka wā kahiko, ka elasticity kiʻekiʻe a me ka pale ʻana i ka aila, a maʻalahi ke hana a hana;
ʻO ka mea TPE he paʻi palupalu, kūpaʻa maikaʻi i ka wā a ʻaʻohe plasticizer.He mea pili kaiapuni a ʻaʻohe mea ʻawaʻawa me ke kumu kūʻai o 20000-50000 / ton.Hoʻohana nui ʻia ia i nā mea e pono ai i kēlā me kēia lā e pili ana i ke kino kanaka.No ka mea hiki ke 100% hana hou ʻia ka ʻōpala TPE, mālama i ke kumukūʻai, hana maʻalahi a me ka hana ʻana, a ʻaʻohe pono vulcanization, hiki ke hana ʻia e nā mīkini hoʻoheheʻe thermoplastic maʻamau.ʻO nā ʻano hana e pili ana i ka injection molding, extrusion, blow molding, calendering, etc.
He maʻalahi, palupalu a hoʻohana nui ʻia nā mīkina lima CPE
