ʻO Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer e holomua ana i ka ʻenehana EVA foam

wehewehe:

ʻO ka Ethylene vinyl acetate (EVA) he copolymer maʻamau i hana ʻia e ka hui ʻana i nā monomers ethylene a me vinyl acetate. Hiki ke hoʻololi ʻia ka hapa o ka vinyl acetate (VA) ma EVA mai ka 2% a i ka 60%, e ʻae ana i ka hoʻoponopono ʻana i kāna mau waiwai. ʻO ka EVA me ka VA haʻahaʻa haʻahaʻa, ma kahi o 3 wt%, hoʻohana mau ʻia e hoʻololi i ka polyethylene, ʻoiai nā haku mele me ka maʻiʻo VA kiʻekiʻe, mai 5 a 50 wt%, loaʻa nā noi i ka hana ʻana i nā kiʻiʻoniʻoni hiki ke emi, ka meaʻai, a me nā kāmaʻa, a me nā mea ʻē aʻe.

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 hoʻomaikaʻi ʻana i ka hoʻomaikaʻi ʻana o Eva foaming holo kāmaʻa ʻenehana. 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.

Nā Pōmaikaʻi Nui

01

E hoʻomaikaʻi i ka elasticity o nā mea pahu EVA

Ke hoʻohālikelike ʻia me ka pauka talcum a i ʻole anti-abrasion agent, ʻoi aku ka maikaʻi o ka elasticity Si-TPV.
02

E hoʻomaikaʻi i ka saturation kala o nā mea pahu EVA

Hiki i kekahi mau hui ma Si-TPV ke launa pū me nā chromophores dye, e hoʻonui ana i ka saturation kala.
03

E ho'ēmi i ka emi ʻana o ka wela o nā mea pahu EVA

ʻO ka elasticity o Si-TPV e kōkua i ka hoʻokuʻu ʻana i ke koʻikoʻi kūloko o nā mea ʻona EVA.
04

E hoʻomaikaʻi i ka hoʻohana ʻana i ka pale anti-abrasion o nā mea pahu EVA

Hiki iā Si-TPV ke komo i ka hopena o ka mea hoʻopili keʻa, kahi e hoʻonui ai i ka mānoanoa crosslinking.
05

Heterogene nucleation

Hoʻopuehu like ʻia ʻo Si-TPV i loko o ka EVA foam material, hiki ke kōkua i ka nucleation cell.
06

E ho'ēmi i ka hoʻololi ʻana o ka hoʻoemi ʻana o nā mea ʻala EVA

Loaʻa i ka Si-TPV ka hana kūʻē kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, a hiki i ka manawa hoʻokahi ke hoʻomaikaʻi i ka deformation kiʻekiʻe a me ka haʻahaʻa wela o ka ʻoi aku ka paʻakikī o ka EVA foam material.

Hoʻomau mau

ʻO ka ʻenehana hoʻoheheʻe ʻole ʻoi loa, me ka ʻole o ka plasticizer, ʻaʻohe ʻaila palupalu, a me ka ʻala ʻole.
Ka palekana a me ka hana hou.
Loaʻa i loko o nā hoʻoponopono hoʻoponopono.

Alakaʻi hoʻohua EVA

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

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.

Ka hoohalike ana o Si-TPV2250-75A a me nā hopena hoʻohui polyolefin elastomer i loko o ka pahu EVA

Palapala noi

Ma ka hoʻokomo ʻana i nā mea hoʻololi Si-TPV i kāu kaʻina hana, hiki i nā ʻoihana ke hana i nā mea hoʻoheheʻe EVA 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.

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 ʻia me nā mea hoʻololi e like me OBC a me POE, ʻo nā mea koʻikoʻi nui o Si-TPV: ● E hoʻomaikaʻi i ka elasticity o nā mea EVA foam ● E hoʻomaikaʻi i ka saturation kala o nā mea EVA foam ● E hoʻemi i ka wela wela o nā mea EVA foam. deformation o kiʻekiʻe-paʻakikī EVA kumumea mea
