ʻO Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer he mea hoʻololi EVA foam maʻemaʻe maʻalahi. Hiki ke hoʻohana ʻia e like me Modifier EVA foam no ka noho ʻana, Modifier Hiki ke hoʻohana ʻia e like me Modifier EVA foam no ka noho ʻana, Modifier EVA foam no nā lako pale, Modifier EVA foam no ke kūkulu ʻana i nā mea pāʻani, Modifier EVA foam no nā kiaʻi shin, a hiki iā ia ke hoʻomaʻamaʻa i ka ka hoʻomaikaʻi ʻana i ka ʻenehana Eva foaming running shoes. Loaʻa iā ia nā pōmaikaʻi o ka hōʻemi ʻana i ka wela o ka EVA foam, ka hoʻomaikaʻi ʻana i ka resilience a me ka pale ʻana i ka abrasion, ka hoʻomaikaʻi ʻana i ka deformation compression o ka mea, a me ka hoʻolaha ʻana i nā lua bubble i ʻoi aku ka like a me ka paʻa.

ʻAʻole like me kona semi-crystalline counterpart, polyethylene, ka hoʻokomo ʻana o nā monomers VA e hoʻopau i ka hoʻokumu ʻana o nā kristal i loko o ke kaulahao polymer, e hoʻemi ana i ka crystallinity. Ke piʻi aʻe nei ka maʻiʻo VA, lilo ka EVA i ka amorphous, e alakaʻi ana i nā loli i kona mau waiwai kino a me ka mechanical. ʻOiai ʻo nā ʻāpana e like me ka elongation ma ka haʻihaʻi, ka mahana hoʻololi aniani, a me ka hoʻonui ʻana me ka maʻiʻo VA kiʻekiʻe, ʻo nā mea ʻē aʻe e like me ka ikaika tensile, modulus, paʻakikī, a me ka hoʻoheheʻe ʻana o ka wela. Eia nō naʻe, ʻoiai ka hoʻonui ʻia ʻana o ka elasticity, hiki i ka EVA ke hōʻike i nā hemahema o ka ikaika o ka waimaka, ke kūpaʻa ʻaʻahu, a me ka hoʻonohonoho paʻa ʻana, ʻoi loa i nā noi e koi ana i ka ikaika.

No ka lanakila ʻana i kēia mau palena, hoʻohui pinepine ʻia ʻo EVA me nā rubbers a i ʻole thermoplastic elastomers (TPEs), e hoʻomaikaʻi ana i ka ikaika tensile, ka pale ʻana i ka waimaka, ka pale ʻana i ka abrasion, a me ke kūpaʻa kemika i hoʻohālikelike ʻia me ka EVA maʻemaʻe. ʻO ka hui ʻana o EVA me nā TPE e like me ka thermoplastic polyurethane (TPU) a i ʻole polyolefin elastomers (POE) e hoʻonui i nā waiwai viscoelastic a hoʻomaʻamaʻa i ka hana a me ka hana hou. Eia kekahi, ʻo ka puka ʻana mai o ka olefin block copolymers (OBC) hāʻawi i nā hiʻohiʻona elastomeric a me ke kūpaʻa kiʻekiʻe. ʻO ka hoʻolālā kūʻokoʻa o OBC, i loaʻa i nā ʻāpana paʻakikī crystallizable a me nā ʻāpana palupalu amorphous, hiki ke hana i ka hana ʻoi aku ka maikaʻi ma nā noi like ʻole, me nā waiwai hoʻonohonoho hoʻokūkū e like me TPU a me TPV.
Eia naʻe, ʻo SILIKE Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer advances he mea hoʻololi hou i ka vulcanizate thermoplastic Silicone-based elastomer modifier. Hoʻohālikelike i nā mea hoʻololi e like me OBC a me POE, ʻo nā mea koʻikoʻi o Si-TPV: ● Hoʻonui i ka elasticity o nā mea EVA foam. o ka EVA foam mea ● Si-TPV hiki i ka manawa like ke hoʻomaikaʻi i ka kiʻekiʻe a me ka haʻahaʻa-mehana hoʻopiʻi deformation o kiʻekiʻe-paʻakikī EVA mea pahu

Palapala noi

Ma ka hoʻokomo ʻana i nā mea hoʻololi Si-TPV i kāu kaʻina hana hana, hiki i nā ʻoihana ke hana i nā mea EVA foam i hāʻawi ʻia me ka hoʻomaikaʻi ʻana i ke kūpaʻa, ka lōʻihi, a me ka hōʻoluʻolu, e hoʻolako i nā noi like ʻole, me nā kapuaʻi kāmaʻa, nā huahana maʻemaʻe, nā mea leʻaleʻa haʻuki, moena papahele/yoga, a me nā mea hou aku. .

Alakaʻi hoʻohua EVA

Loaʻa iā Si-TPV 2250 nā hiʻohiʻona o kahi paʻi palupalu ʻili lōʻihi, kūpaʻa maikaʻi i ka ʻili, ʻaʻohe plasticizer a me ka softener i hoʻohui ʻia, ʻaʻohe ua ma hope o ka hoʻohana lōʻihi, ʻoi aku ka maikaʻi no ka Super light high elastic eco-friendly EVA hoʻomākaukau ʻana i nā mea huʻa.

Hoʻohou i nā mea EVA Foam (4)

Ma hope o ka hoʻohui ʻana iā Si-TPV 2250-75A, e hoʻemi iki ka nui o ka puʻupuʻu pūpū o ka EVA foam, ka mānoanoa o ka pā o ka ʻōpū, a hoʻopuehu ʻia ʻo Si-TPV i loko o ka pā ʻūlū, lilo ka pā o ka ʻōhū.
