He aha nā ʻokoʻa ma waena o EVA, EPE a me nā mea sponge?

EVAhana ʻia mai ka copolymerization o ka ethylene (E) a me ka vinyl acetate (VA), i kapa ʻia ʻo EVA, a he mea maʻamau maʻamau ka midsole. He ʻano hou ʻo EVA o nā mea hoʻopili pili kaiapuni. Hana ʻia ia me ka EVA foam, ka mea e lanakila ai i nā hemahema o ka pahu pahu maʻamau e like me ka brittleness, deformation, a me ka hoʻihoʻi maikaʻi ʻole. He nui kona mau pono e like me ka wai a me ka moisture proof, shockproof, sound insulation, heat preservation, good plasticity, strong toughness, recycling, environmental protection, impact resistance, anti-slip and shock resistance, etc. he mea hoʻopili kuʻuna kūpono. nā mea ʻē aʻe. Loaʻa i ka EVA ka plasticity ikaika loa. Hiki ke ʻoki ʻia i loko o kekahi ʻano, a hiki ke hoʻopili ʻia e like me nā kiʻi o nā mea kūʻai aku. Hiki ke hoʻopilikinoʻia kaʻeke waihona EVA me ke kala, ka lole a me ka lining i makemakeʻia e ka mea kūʻai. Hoʻohana nui ʻia ʻo EVA i ka shockproof, anti-slip, sealing a me ka mālama ʻana i ka wela o nā mea uila, ka uhi ʻana o nā pahu pahu like ʻole, nā kini metala a me nā ʻoihana ʻē aʻe. Nā hana e like me ka pale, anti-static, fireproof, shockproof, mālama wela, anti-slip, a paʻa. ʻAʻahu-pale a me ka wela. Insulation a me nā hana ʻē aʻe.

ʻO ka inoa ʻepekema o EPE he polyethylene hiki ke hoʻonui ʻia, ʻike ʻia hoʻi he pulu momi. He ʻano hou ia o ka mea hoʻopili mea hiki ke hōʻemi a hoʻopaʻa i ka vibration. He huahana polyethylene kiʻekiʻe ia i hoʻokuʻu ʻia mai ka polyethylene haʻahaʻa haʻahaʻa (LDPE) ma ke ʻano he kumu nui. Hoʻopili ʻia ka pulupulu momi EPE i nā ʻano ʻano kūikawā me ka hoʻohana ʻana i ka butane, kahi e hoʻomāhuahua ai ka EPE, ʻoʻoleʻa akā ʻaʻole palupalu, me ka ʻili palupalu. Hiki iā ia ke pale pono i ka pōʻino i hoʻokumu ʻia e ka friction i ka wā o ka hoʻopili ʻana o ka huahana a loaʻa iā ia ka haʻalulu haʻalulu maikaʻi a me nā waiwai kūʻē. . I kēia manawa, hoʻohana nui ʻia ia i ka hoʻopili ʻana i nā mea uila, nā lako, nā mea uila pololei a me nā huahana ʻē aʻe. Paʻa ka pulupulu momi EPE i ka aila mīkini, ka momona, a me nā mea ʻē aʻe. Hiki iā ia ke hōʻoia i ka ʻaila, ka moisture-proof, shock-proof, sound insulation and heat insulation, a hiki nō hoʻi ke pale aku i ka erosion o nā pūhui he nui. Hiki i ka pulupulu momi EPE ke hoʻokō i nā koi hoʻopihapiha like ʻole, antistatic, flame retardant, etc. e like me nā pono o nā huahana like ʻole. Loaʻa iā ia nā waihoʻoluʻu momona a maʻalahi ke hana.
ʻO ka inoa ʻepekema o ka sponge he polyurethane soft foam rubber, nona ka hoʻohana ʻana i ka haʻalulu, anti-friction, a me ka hoʻomaʻemaʻe. Hoʻokaʻawale ʻia nā ʻano i ka sponge polyester a me ka sponge polyether, i hoʻokaʻawale hou ʻia i ʻekolu mau ʻano: kiʻekiʻe rebound, medium rebound a me slow rebound. He palupalu ka sponge i ke ʻano, kū i ka wela (hiki ke kū i kahi mahana o 200 degere), a maʻalahi ke puhi (hiki ke hoʻohui ʻia nā mea pale ahi). Ma muli o ka nui o nā ʻōpū o loko, hiki iā ia ke hōʻike i nā density like ʻole a hiki ke hoʻoheheʻe ʻia i nā ʻano like ʻole e like me ka mea e pono ai. Loaʻa iā ia kahi ākea ākea a hoʻohana nui ʻia i ka shockproof, thermal insulation, hoʻopiha waiwai, nā mea pāʻani keiki, etc.

ʻO nā ʻokoʻa nui ma waena o nā ʻekolu penei:
1. Hiki iā mākou ke ʻike i ka ʻokoʻa ma waena o lākou me ko mākou mau maka. ʻO Sponge ka māmā o nā ʻekolu. He melemele liʻiliʻi a lohi. ʻO EVA ka mea kaumaha ma waena o nā ʻekolu. He ʻeleʻele a ʻano paʻakikī. He keʻokeʻo ka pulupulu momi EPE, he maʻalahi ke hoʻokaʻawale ʻana mai ka ʻōhuʻu. E hoʻi ʻakomi ka ʻōhuʻu i kona ʻano kumu ʻoiai ke kaomi ʻana iā ia, akā ʻo ka pulupulu momi EPE e pohu wale a kani ka leo popping ke kaomi ʻoe.
2. Hiki iā ʻoe ke ʻike i nā hiʻohiʻona wavy ma ka pulupulu momi EPE, e like me ka nui o ka huʻa i hoʻopili ʻia, ʻoiai ʻo EVA ke ʻano a hiki ke hoʻokaʻawale ʻia e like me kona ʻike.
