Mea hoʻohūhū EVA

ʻO EVA ka hā o ka polymer series ethylene nui ma hope o HDPE, LDPE a me LLDPE.Ke hoʻohālikelikeʻia me nā mea kahiko,ʻoi aku ka haʻahaʻa o kona kumukūʻai.Manaʻo ka poʻe he nui ka EVA foam material ʻo ia ka hui pū ʻana o ka pūpū paʻakikī a me ka pūpū palupalu, e mālama ana i nā pono o ka ʻūhā palupalu a me ka paʻakikī ʻoiai e haʻalele ana i nā hemahema.Eia kekahi, ʻo ka maʻalahi o ka hoʻolālā waiwai a me nā mea hana hana ke kumu nui i kekahi o nā ʻoihana alakaʻi o ka honua a me nā hōʻailona e huli ana i ka EVA foam ke koi ʻia nā mea hana kiʻekiʻe a me nā kumu kūʻai haʻahaʻa.

ʻOi aku ma mua o ka maʻalahi, mālama ʻo EVA foam material i ko mākou ola i kēlā me kēia lā a me nā hana ʻoihana, a ua loaʻa i ka makemake o nā mea hoʻohana hope.ʻO nā kāmaʻa wāwae, nā lāʻau lapaʻau, nā paneli photovoltaic, nā huahana haʻuki a me nā leʻaleʻa, nā mea pāʻani, nā moena papahele/yoga, hoʻopili, nā mea lapaʻau, nā mea pale, wat

Ke koi ikaika nei nā huahana haʻuki no nā huahana plastik lōʻihi, a ke hoʻomau nei ka mākeke EVA foam material i ka ulu hou o.

丨EVA mau waiwai kino a me ka mechanical

Hoʻoholo nui ʻia nā waiwai o nā copolymers EVA e ka ʻike vinyl acetate a me ke kiʻekiʻe o ka wai.ʻO ka hoʻonui ʻana i ka maʻiʻo VA e hoʻonui i ka nui, ka ʻike a me ka maʻalahi o ka mea i ka wā e hoʻemi ana i ka helu heheʻe a me ka paʻakikī.ʻO ka Ethylene-vinyl acetate copolymer (EVA) he mea elastic loa ia i hiki ke hoʻopaʻa ʻia e hana i ka ʻūhā like me ka lāʻau, akā me ka ikaika maikaʻi loa.ʻEkolu manawa ʻoi aku ka maʻalahi ma mua o ka haʻahaʻa haʻahaʻa polyethylene (LDPE), he tensile elongation o 750%, a he 96°C ka wela hoʻoheheʻe kiʻekiʻe.

Ma muli o nā mea i loko o ke kaʻina hana, hiki ke hoʻokō i nā pae like ʻole o ka paʻakikī EVA.He mea nui ka mālama ʻana i ka pae haʻahaʻa o ka paʻakikī no ka mea ʻaʻole i loaʻa hou ka EVA i kona ʻano ma hope o ka hoʻomau mau ʻana.Ke hoʻohālikelike ʻia me ka EVA ʻoi aku ka paʻakikī, ʻoi aku ka liʻiliʻi o ka EVA palupalu i ka abrasion a ʻoi aku ka pōkole o ke ola ma ka wāwae, akā ʻoi aku ka ʻoluʻolu.

丨 mau waiwai wela EVA

Ke emi nei ka helu heheʻe o EVA me ka piʻi ʻana o ka waihona VA.No laila, ʻoi aku ka haʻahaʻa o ka hoʻohana ʻana o ka copolymer i ka homopolymer pili (LDPE).ʻOi aku ka liʻiliʻi o ka wela hana o ka mea hana ma mua o ka wela o ka hoʻomaʻamaʻa ʻana iā Vicat.E like me nā polymers thermoplastic āpau, pili ka mahana i ka lōʻihi a me ke kiʻekiʻe o ke koʻikoʻi mechanical kahi i hoʻokau ʻia ai ka mea hana i ka wela.Ke piʻi aʻe ka mahana, emi ka mahana conductivity a hiki i kahi pāpū kokoke i ka helu heheʻe.
