Okoa a me na ano o TPU, Rubber a me Silicone
Definition
TPU Ke wehewehe:
TPU He ʻano ʻano o ka thermoplastic elastomer (TPE), ʻo ia ka mea e kū nei polyurethane thermoplastic elastomer. He pili kaiapuni, ʻaʻohe mea ʻawaʻawa, a hiki ke hana hou ʻia. TPU loaʻa i ka pale lole maikaʻi, elasticity, a me ka pale ʻaila. ʻO kona paʻakikī mai ka 70A a hiki i ka 98A, a ʻo kona kala kumu he aniani.
Wehewehe Rubber:
Hiki ke hoʻokaʻawale ʻia ka Rubber i ka lāʻau kūlohelohe a me ka synthetic rubber e like me nā mea maka. Wehe ʻia ka lāʻau lapaʻau maoli mai nā kumulāʻau lāʻau lapaʻau, ʻoiai ua hana ʻia ka lāʻau synthetic. Loaʻa i ka Rubber nā ʻano like ʻole a me nā degere o ka pale ʻana. ʻO ka Rubber kahi polymer amorphous loa, he elastic ma ka lumi wela a hiki ke hana i ka deformation nui ma lalo o ka ikaika liʻiliʻi o waho. Ma hope o ka wehe ʻana i ka ikaika o waho, hiki iā ia ke hoʻihoʻi i kona ʻano kumu.
ʻO ka ʻōlelo Silicone:
ʻO ka Silicone kahi mea hoʻoheheʻe nui loa i pili i ke kaiapuni, ʻaʻohe mea ʻawaʻawa, a me ka ʻala ʻole. Loaʻa iā ia ka hana adsorption kiʻekiʻe, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai, maikaʻi ke kūpaʻa wela a me ka paʻa kemika, a he ikaika mechanical kiʻekiʻe.
Nā ʻokoʻa a me nā ʻano:
He palupalu ka manaʻo o ka silicone, a ʻaʻole maikaʻi kona elasticity TPU. Pilikia a maʻalahi ka huki ʻana i ka lepo, a paʻakikī ke hoʻomaʻemaʻe. ʻAʻole ikaika kona hanu e like me TPU, a ke hoʻohana ʻia e hana i nā hihia kelepona a me nā hihia palekana huahana uila ʻē aʻe, hiki ke hōʻemi i ka wela wela no ke kelepona. He pōʻino nō hoʻi ka Silicone no ka mea ʻilihune kona pale ʻana i ka waimaka a haʻahaʻa kona ikaika tensile. ʻO ka pōmaikaʻi wale nō, ʻoi aku ka maikaʻi ma mua o TPU. TPU ʻO nā hihia kelepona waiwai a me nā uhi pale e lanakila ai i nā hemahema o nā hihia kelepona silicone, me ke kūpaʻa ʻaʻahu maikaʻi, ke kūpaʻa ʻana, ka pale ʻana i ka hopena, ka haʻalulu haʻalulu, a me ka elasticity. TPU ʻO nā hihia kelepona he maloʻo a ʻoluʻolu hoʻi, ʻaʻole e luhi i ke kelepona, ʻaʻole e huki i ka lepo, a maʻalahi hoʻi e hoʻomaʻemaʻe, e lilo i mea kaulana i waena o nā mea kūʻai aku a me nā mea hana. I ka hoʻohālikelike ʻana me ka rubber, TPU Loaʻa nā pōmaikaʻi i ka pale ʻana i ka ʻaʻahu, ka ikaika mechanical, ka elasticity, a me ka haʻahaʻa haʻahaʻa haʻahaʻa, ʻoiai ʻoi aku ka maikaʻi o ka pale ʻana i ke kapa komo. TPU He kūpaʻa haʻahaʻa haʻahaʻa maikaʻi a hiki ke loaʻa i ka elasticity maikaʻi a me ka paʻakikī ma -50 ℃, ʻoiai ʻaʻole hiki i ka lāʻau ke lilo a palupalu a maʻalahi hoʻi e haki. I kēia manawa, nui nā huahana ma ka mākeke i hana ʻia i ka lāʻau lapaʻau no ka mea he maʻalahi a haʻahaʻa. I ka ʻoiaʻiʻo, TPU Hiki i nā mea waiwai ke pani i ka lāʻau i nā hana he nui. I ka wā e hiki mai ana, TPU e lilo i kekahi o nā mea maka i kaulana loa no ka hana ʻana.
Pehea e hoʻokaʻawale ai?
No laila, i ke kaʻina hana a me ka hoʻohana ʻana, pehea mākou e hoʻokaʻawale ai TPU, ka pulupulu, a me ka silicone? Hiki iā mākou ke hoʻokaʻawale maikaʻi i kēia mau mea ʻekolu ma o ka puhi ʻana, honi, paʻakikī, etc.
TPU (ka polyurethane thermoplastic):
He melemele ka lapalapa e ʻā ana, me ke kani liʻiliʻi a pahū; he ʻala kūikawā kona (ke ʻala o ka amonia); TPU he mau ʻāpana alohilohi, a hiki ke hoʻohālikelike ʻia me ke keʻokeʻo a ʻeleʻele paha. ʻO ka laulā paʻakikī he 60A ~ 80D.
Rubber (ʻano vulcanized):
He melemele ka lapalapa ahi, a ʻoi aku ka nui o ka ʻala o ka ʻaʻala (ʻala ʻala, nā mea vulcanizing agents, anti-aging agents a me nā mea hoʻohui ʻē aʻe e puhi i ka hana); ʻeleʻele nā huahana vulcanized rubber, akā he waiū keʻokeʻo a melemele paha; ʻO ka paʻakikī o ka mea maʻamau he 50 ~ 80A. Loaʻa i nā huahana Rubber ke kūpaʻa maikaʻi loa.
Silicone:
ʻO ka lapalapa ahi keʻokeʻo keʻokeʻo, me kaʻala māmā, emi ka uahi, aʻo ke koena he pauda keʻokeʻo; loaʻa i ka silicone nā ʻāpana aniani, a me nā mea paʻa paʻa ʻole; māhele ʻia i ka silicone anorganic a me ka organik; ʻO ka laulā paʻakikī he 10 ~ 90A. Loaʻa ka Silicone i ka tensile resilience maikaʻi loa.
