ʻO wai ka mea ʻoi aku ka maikaʻi, ka band resistance latex a i ʻole ka band resistance tpe?

1. Nā hiʻohiʻona o TPEhui kūʻē

Loaʻa i nā mea TPE ke kūpaʻa maikaʻi a me ka ikaika tensile, a ʻoluʻolu a maʻalahi.Hoʻopuka pololei ʻia a hoʻokumu ʻia e kahi extruder, a maʻalahi a maʻalahi ka hana.ʻAʻole maikaʻi ka ʻaila o TPE.Puhi ʻo TPE me kahi ʻala palupalu, a liʻiliʻi a māmā ka uahi.

 ʻO ka mea TPE kahi mea i hoʻololi ʻia i hui ʻia, a ʻo kona mau waiwai kino he nui ka hoʻololi ʻana, a ʻo ka gravity kikoʻī ma waena o 0.89 a me 1.3.ʻO ka paʻakikī ma waena o 28A-35A Shore.ʻO ka paʻakikī kiʻekiʻe a haʻahaʻa paha e pili ana i ka hana o kahui kūʻē.

 ʻO ka TPEhui kūʻē hoʻohana nā mea i ka SEBS i mea nui.ʻO SEBS kekahi mea pili i ke kaiapuni e kū ana i ka maʻamau REACH, no laila ʻaʻole ia e hoʻoulu i nā hopena maʻi i nā hui kūikawā.ʻO ke kāʻei elastic i hana ʻia me TPE he ʻili maʻemaʻe, ʻaʻohe ʻāpana a me nā mea ʻē aʻe, a ke mālama mau nei i ka elasticity maikaʻi loa i kahi ʻano wela haʻahaʻa me ka ʻole o ka paʻakikī a me ka palupalu.Kūleʻa maikaʻi i ka wā, hiki ke hoʻohana ʻia i loko o kahi kaiapuni o 40-90 degere Celsius, a ʻaʻohe ʻāʻī i ka hoʻohana ʻana i waho i loko o kēia pae wela.

 ʻO ka mea nui i hoʻohana ʻia ma TPE, SEBS, aia ka nui o ka butadiene, nona nā hiʻohiʻona o ke kiʻekiʻe kiʻekiʻe a me ka liʻiliʻi deformation.Ua hoʻāʻo mākou ʻo ka hoʻolōʻihi ʻana i nā manawa 3 no nā manawa ʻoi aku ma mua o 30,000 mau manawa e hana i kahi deformation liʻiliʻi, akā ʻaʻole ʻoi aku ma mua o 5%.

 2. Nā ʻano o ka latexhui kūʻē

Loaʻa i ka Latex ke kūpaʻa ʻaʻahu maikaʻi, ke kūpaʻa wela, ka elasticity kiʻekiʻe, ka ikaika o ka waimaka a me ka elongation ma mua o 7 mau manawa.He mea maʻalahi ka makahiki i ka lewa, keʻokeʻo ke kāpīpī i ka hau.Ma muli o ka loaʻa ʻana o nā molekole protein heterogenous i loko o ka latex maoli, hiki ke hoʻoulu i ka maʻi maʻi i kekahi poʻe.

 Ua ʻoki ʻia ka latex maoli mai ka lāʻau lapaʻau.He ʻano ʻōpala maoli.He wai, waiu keʻokeʻo, a ʻono ʻole.He 27% a hiki i ka 41.3% o ka latex maoli, 44% a 70% o ka wai, 0.2% a 4.5% o ka protein, 2% a 5% o ka resin maoli, 0.36% a 4.2% o ke kopaa, a me 0.4% o ke ko. lehu.I mea e pale aku ai i ka latex maoli mai ka coagulating ma muli o kāna mau microorganisms a me nā enzymes, hoʻohui pinepine ʻia ka ammonia a me nā mea hoʻokele kemika.

 Resistance band ʻoi aku ka maikaʻi o ka latex a ʻoi aku ka maikaʻi o ka tpe, loaʻa iā lāua nā pono a me nā hemahema.Hoʻohana ʻia ma ke kahua ohui kūʻēs, hiki i ke koho o ka mea TPE ke hoʻohana pono i kāna hana, a ʻoi aku ke kumukūʻai.Ke hoʻohālikelike nei i nā mea ʻelua, ʻaʻohe maikaʻi a maikaʻi ʻole.Pono mākou e hoʻoholo e like me ka hana a me nā koi noi o ka huahana.

2. ʻO ka ʻokoʻa ma waena o TPUhui kūʻē a me TPEhui kūʻē

ʻOiai ʻo TPU a me TPE kahi ʻokoʻa leka, ʻo ka hoʻohana ʻana o TPUhui kūʻē a me TPEhui kūʻē ʻokoʻa loa.ʻO ke kiʻi liʻiliʻi o ka TPUhui kūʻē 'ālohilohi i ke kahua o nā mea ʻaʻahu i ulana ʻia, e like me ke kola a me nā puʻupuʻu o nā lole i ulana ʻia, ka poʻohiwi a me nā ʻaoʻao ʻaoʻao.ʻO ka mea a TPE elasticity e lawe ai i ke ala ikaika he kūlana i loko o nā mea hoʻoikaika kino, e like me ka hoʻoikaika kinohui kūʻēs, nā mea hana hoʻoikaika kino nā pūʻulu hoʻopaʻapaʻa a pēlā aku.ʻO TPU pahahui kūʻē a i ʻole TPEhui kūʻē, ua pili kaiapuni a lōʻihi.ʻO ka ʻokoʻa koʻikoʻi ma waena o lākou ʻo ka ʻokoʻa i ka laulā o ka helehelena a me ka mānoanoa a me ke ʻano o ka hoʻohana.ʻOiaʻiʻo, ʻokoʻa iki nā mea maka.

 1. ʻO ka ʻokoʻa o ka helehelena a me ka laulā o ka hoʻohana

 ʻO ke kala o ka TPUhui kūʻē ʻO ka mānoanoa o ka hau hau, ʻo ka laulā ma waena o 2MM a me 30MM, a ʻo ka mānoanoa ma waena o 0.08MM a me 1MM.Hoʻohana ʻia ia i ke kola a me nā ʻūhā o nā lole i ulana ʻia, a ua hoʻohālikelike ʻia nā ʻāpana ʻaoʻao o ka poʻohiwi e hāʻawi i kahi hopena maikaʻi ʻole.ʻAʻole pono e noʻonoʻo i ka hoʻohālikelike kala;ʻO kona laulā e like me ka laulā o nā humuhumu, kahi e maʻalahi ai ka hūnā i ke kāʻei;ʻaʻole e pili ka mānoanoa ʻano lahilahi i ka ʻoluʻolu o nā lole i ulana ʻia ma hope o ke humuhumu ʻana.

 ʻO ke kala o TPEhui kūʻē ʻoi aku ka ʻokoʻa, e like me ke kala maoli, uliuli, melemele, ʻōmaʻomaʻo, ʻulaʻula, ʻalani, poni, poni, etc. ., He ʻokoʻa nā kala a maʻalahi no nā mea hoʻohana e koho.No ka mea, ʻo ka TPEhui kūʻē ʻoi aku ka laulā a ʻoi aku ka mānoanoa, hiki iā ia ke kū i ka ʻoluʻolu maikaʻi a kūpono hoʻi no ka hoʻohana ʻana i nā mea hoʻoikaika kino.

 2. ʻO ka ʻokoʻa ma waena o nā mea maka

 ʻO ka TPU a me ka TPE nā mea thermoplastic me ka elasticity rubber, a ua loaʻa iā lāua ka elasticity rubber maikaʻi.I ka hoʻohālikelike ʻana, ʻoi aku ka maikaʻi o TPE ma ke ʻano o ka hōʻoluʻolu tactile, a ʻoi aku ka maikaʻi o ka elasticity a me ka ikaika o TPU.He paʻakikī ke hoʻokaʻawale ma waena o TPE a me TPU ma o ka nānā ʻana wale nō.E hoʻomaka me nā kikoʻī e nānā i nā ʻokoʻa a me nā ʻokoʻa ma waena o TPE a me TPU:

 1) ʻOi aku ka maikaʻi o ka TPU ma mua o ka TPE, a ʻaʻole maʻalahi ke hoʻopili e like me ka TPE māmā;

 2) 'Oko'a ka umekaumaha kiko'ī o TPU, mai ka 1.0 a hiki i ka 1.4, a'o ka TPE ma waena o 0.89 a hiki i ka 1.3, ma ke 'ano o ka hui 'ana, no laila e loli nui ka 'umekaumaha;

 3) Ua ʻoi aku ka maikaʻi o ka ʻaila ʻoi aku ka maikaʻi o ka TPU, ʻoiai ʻoi aku ka maikaʻi o ka ʻaila o TPE;

 4) Puhi ʻo TPU me ka ʻala māmā, me ka uahi liʻiliʻi a me ka māmā, a aia kahi kani pahū liʻiliʻi i ka wā e ʻā ai, ʻo TPE kahi ʻala māmā i ka wā e ʻā ana, a ʻoi aku ka liʻiliʻi o ka uahi;

 5) ʻOi aku ka maikaʻi o ka elasticity a me ka elastic recovery o ka TPU ma mua o TPE;

 6) ʻO ka pale wela o ka TPU -60 degrees Celsius a 80 degrees Celsius, TPE -60 degrees Celsius i 105 degrees Celsius;

 7) Ma ke ʻano o ka hiʻohiʻona a me ka manaʻo, no kekahi mau huahana overmolded, ʻoi aku ka ʻino o nā huahana TPU a me ke kūpaʻa frictional ikaika ma mua o nā huahana TPE;ʻoiai ʻo nā huahana TPE he ʻano palupalu a palupalu a nāwaliwali hoʻi ka hana friction.

 Ma keʻano laulā, ka TPUhui kūʻē he alohilohi a hau, māmā a palupalu, he kūpaʻa maikaʻi, ʻoʻoleʻa maikaʻi, a ʻaʻole maʻalahi e haki.He kūpono ia no ka hoʻonohonoho ʻana i ke humu ʻaoʻao o ka ʻaoʻao o ka ʻāʻī knitwear collar cuff hemming.ʻO ka TPEhui kūʻē he ʻano kala like ʻole, ʻoluʻolu i ka hoʻopā ʻana, he kiʻekiʻe kiʻekiʻe ke kau ʻana, a he kūpaʻa maikaʻi loa.He kūpono ia no ka hoʻohana ʻana i nā mea hoʻoikaika kino.
