Hoʻolaha ka Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer i ka ʻenehana EVA foam

wehewehe:

ʻO ka Ethylene vinyl acetate (EVA) kahi copolymer versatile i hoʻokumu ʻia ma ka hoʻohui ʻana i nā monomers ethylene a me vinyl acetate. Hiki ke ʻokoʻa ka hapa o ka nui o ka vinyl acetate (VA) i loko o ka EVA mai 2% a 60%, e ʻae ana i ka hoʻopilikino ʻana i kona mau waiwai. ʻO ka EVA me ka nui o ka VA haʻahaʻa, ma kahi o 3 wt%, hoʻohana pinepine ʻia e hoʻololi i ka polyethylene, ʻoiai ʻo nā hui me ka nui o ka VA kiʻekiʻe, mai 5 a 50 wt%, loaʻa nā noi i ka hana ʻana i nā kiʻiʻoniʻoni shrinkable, ka ʻōpala meaʻai, a me nā kāmaʻa, a me nā mea ʻē aʻe.

ʻO ka elastomer silicone thermoplastic vulcanizate dynamic Si-TPV kahi mea hoʻololi EVA maʻemaʻe maʻalahi hou. Hiki ke hoʻohana ʻia ma ke ʻano he Modifier EVA foam no ka noho ʻana, Modifier Hiki ke hoʻohana ʻia ma ke ʻano he Modifier EVA foam no ka noho ʻana, Modifier EVA foam no nā lako pale, Modifier EVA foam no nā mea pāʻani kūkulu hale, Modifier EVA foam no nā pale shin, a hiki iā ia ke hoʻomaʻamaʻa i ka hoʻonui ʻana i ka ʻenehana Eva foaming running shoes. Loaʻa iā ia nā pono o ka hōʻemi ʻana i ka thermal shrinkage o ka EVA foam, hoʻomaikaʻi i ke kūpaʻa a me ke kū'ē ʻana i ka abrasion, hoʻomaikaʻi i ka deformation compression o ka mea, a me ka hoʻolaha ʻana i nā lua pehu e ʻoi aku ka like a me ka mānoanoa.

Nā Pōmaikaʻi Koʻikoʻi

01

E hoʻomaikaʻi i ka elasticity o nā mea huʻa EVA

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

E hoʻomaikaʻi i ka saturation kala o nā mea huʻa 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 hoʻemi i ka emi ʻana o ka wela o nā mea huʻa EVA

Kōkua ka elasticity o Si-TPV i ka hoʻokuʻu ʻana i ke kaumaha kūloko o ka mea huʻa EVA.
04

E hoʻomaikaʻi i ke kūpaʻa anti-abrasion o nā mea hua EVA

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

Hoʻokumu ʻano like ʻole

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

E ho'ēmi i ka hoʻololi ʻana o ke kaomi ʻana o nā mea huʻa EVA

Loaʻa iā Si-TPV ka hana kū'ē wela kiʻekiʻe a me ka haʻahaʻa, a hiki i ka manawa like ke hoʻomaikaʻi i ka deformation compression wela kiʻekiʻe a me ka haʻahaʻa o nā mea huʻa EVA paʻakikī kiʻekiʻe.

Ke kūpaʻa Ke kūpaʻa

ʻO ka ʻenehana solvent-free holomua, me ka ʻole o ka plasticizer, ʻaʻohe aila palupalu, a ʻaʻohe ʻala.
Ka palekana o ke kaiapuni a me ka hiki ke hana hou ʻia.
Loaʻa i loko o nā ʻano hana hoʻoponopono.

Alakaʻi hoʻohua EVA

Loaʻa i ka moʻo Si-TPV 2250 nā ʻano o ka pā palupalu no ka ʻili i ka wā lōʻihi, ke kūpaʻa maikaʻi i nā ʻōpala, ʻaʻohe plasticizer a me ka softener i hoʻohui ʻia, a ʻaʻohe ua ma hope o ka hoʻohana lōʻihi, ʻoi aku ka kūpono no ka hoʻomākaukau ʻana i ka mea hoʻohua EVA eco-friendly Super light high elastic.

Hana Hou i nā mea EVA Foam (4)

Ma hope o ka hoʻohui ʻana i ka Si-TPV 2250-75A, e emi iki ana ka nui o nā cell pehu o ka huʻa EVA, e mānoanoa ana ka paia pehu, a e hoʻopuehu ʻia ʻo Si-TPV i loko o ka paia pehu, a lilo ka paia pehu i ʻinoʻino.

Hoʻohālikelike ʻana o Si-TPV2250-75A a me nā hopena hoʻohui elastomer polyolefin i ka huʻa EVA

Noi

Ma ka hoʻohui ʻana i nā mea hoʻololi Si-TPV i kāu mau kaʻina hana hana, hiki i nā ʻoihana ke hana i nā mea huʻa EVA i hāʻawi ʻia me ka hoʻoikaika ʻana, ka lōʻihi, a me ka hōʻoluʻolu, e hoʻokō ana i nā noi like ʻole, me nā kapuaʻi kāmaʻa, nā huahana sanitary, nā mea leʻaleʻa haʻuki, nā moena papahele/yoga, a me nā mea hou aku.

ʻAʻole e like me kona hoa semi-crystalline, polyethylene, ʻo ka hoʻokomo ʻana o nā monomers VA e hoʻopilikia i ka hoʻokumu ʻia ʻana o nā kristal i loko o ke kaulahao polymer, e hopena ana i ka emi ʻana o ka crystallinity. I ka piʻi ʻana o ka nui o ka VA, lilo ka EVA i amorphous, e alakaʻi ana i nā loli i kona mau waiwai kino a me nā mechanical. ʻOiai e piʻi ana nā palena e like me ka elongation i ka haki ʻana, ka mahana hoʻololi aniani, a me ka density me ka piʻi ʻana o ka nui o ka VA, ʻo nā mea ʻē aʻe e like me ka ikaika tensile, modulus, paʻakikī, a me ka mahana hoʻoheheʻe e emi ana. Eia nō naʻe, ʻoiai kona elasticity i hoʻonui ʻia, hiki i ka EVA ke hōʻike i nā hemahema i ka ikaika haehae, ke kū'ē ʻana i ke kapa, a me ka hoʻonohonoho compression, ʻoi aku hoʻi i nā noi e koi ana i ka paʻa.

No ka lanakila ʻana i kēia mau palena, hoʻohui pinepine ʻia ʻo EVA me nā rubbers a i ʻole nā thermoplastic elastomers (TPEs), e hoʻomaikaʻi ana i ka ikaika tensile, ke kūpaʻa i ka haehae, ke kūpaʻa i ka abrasion, a me ke kūpaʻa kemika i hoʻohālikelike ʻia me EVA maʻemaʻe. ʻO ka hoʻohui ʻana iā EVA me nā TPE e like me ka thermoplastic polyurethane (TPU) a i ʻole polyolefin elastomers (POE) e hoʻonui i nā waiwai viscoelastic a hoʻomaʻalahi i ka hana ʻana a me ka hana hou ʻana. Eia kekahi, ʻo ka puka ʻana mai o nā olefin block copolymers (OBC) e hāʻawi i nā ʻano elastomeric a me ke kūpaʻa wela kiʻekiʻe. ʻO ke ʻano kū hoʻokahi o OBC, me nā ʻāpana paʻakikī crystallizable a me nā ʻāpana palupalu amorphous, e hiki ai ke hana maikaʻi loa i nā noi like ʻole, me nā waiwai compression set e like me TPU a me TPV.
Eia nō naʻe, ʻo ka holomua o ka SILIKE Si-TPV dynamic vulcanizate thermoplastic silicone-based elastomer he mea hoʻololi elastomer vulcanizate thermoplastic Silicone-based. Ke hoʻohālikelike ʻia me nā mea hoʻololi e like me OBC a me POE, ʻo nā mea nui o Si-TPV: ● Hoʻomaikaʻi i ka elasticity o nā mea EVA foam ● Hoʻomaikaʻi i ka saturation kala o nā mea EVA foam ● Hoʻemi i ka shrinkage wela o nā mea EVA foam ● Hoʻomaikaʻi i ke kū'ē ʻana i ka abrasion o nā mea EVA foam ● Hiki i ka Si-TPV ke hoʻomaikaʻi i ka deformation compression kiʻekiʻe a me ka haʻahaʻa o nā mea EVA foam paʻakikī kiʻekiʻe
