Eva mahuahua (adhesive hoʻoheheʻe wela) kahi laulā o ka hoʻopili ʻana, e like me PA (polypropylene),

PE (polyethylene) a me nā mea pono ʻole polar, akā hiki ke hoʻokō i kahi hopena hoʻopaʻa maikaʻi.

ʻO ka pale lina i ke kūpaʻa wela haʻahaʻa maikaʻi, kūpaʻa wai a me ka wai

kūpaʻa.

Ma muli o ka EVA wax (adhesive hoʻoheheʻe wela) maikaʻi ʻole ka rigidity, he haʻahaʻa haʻahaʻa ia ma mua o

polyester a me polyamide wela hoʻoheheʻe lina, a me kona global palupalu kiko ma kahi o 100 ° C, no laila

palena palena o kāna noi noi.

Hoʻokomo ʻia ʻo Eva Wax (adhesive hoʻoheheʻe wela) na Eva resin, e hoʻopaʻa ana i ka kēpau, ka piula a me ka mea hoʻopaʻa

Hoʻokomo ʻo Eva resin i nā kaulahao lālā pōkole i haku ʻia o nā genes acid polar acetic i loko

nā kaulahao lālā ethylene, i hoʻopilikia i ke ʻano crystalline kumu, i hana ʻia e EVA

"Ka hopena plasticizing", a hoʻemi i ka crystallinity o ka ethylene i nā kaulahao lālā,

e hoʻonui i ka mamao ma waena o nā kaulahao polymer, e hoʻonui ana i ka resin EVA a

lahilahi

ʻO ka ʻike o ka VA ma ke kēpau ʻo Eva hiki mai ka haʻahaʻa a ka pākēneka kiʻekiʻe. No laila, ke

ka pākēneka o VA a me MI (helu hoʻoheheʻe, e hōʻike ana i ke kaumaha o ka mole) i ka kēpau

nā mea nui e hoʻoholo pololei a hoʻohuli i nā waiwai o Eva.

ʻO ka mea maʻamau, kiʻekiʻe ke ʻano o Eva, hoʻonui ʻia ka ikaika paʻa, ka hiki ʻole o ka lina

maikaʻi nā mea, lohi ka hoʻōla ʻana i ka manawa, hoʻemi ʻia ke kūpaʻa wela. Kiʻekiʻena ka helu hoʻoheheʻe,

ʻo ia hoʻi ka haʻahaʻa o ka mole mole, ka viscosity haʻahaʻa, ka hiki ʻana o ka maikaʻi, ke kūpaʻa wela haʻahaʻa

pili mau.

I nā copolymers e pili ana i ka ethylene, ʻoi aku ka nui o ka ikaika o Eva ma mua o EEA (ethylene-Ethyl

acrylate), EAA (ethylene-propylene ester) a me EMA (ethylene-propylene ester), a ʻo ia

ʻokoʻa me ka ʻike o VA. Inā ʻokoʻa ka Mi o EVA, ka loli o ka haki ʻana i ka ʻumi

ʻoi aku ka ikaika.

E emi ka ikaika o ka wax EVA me ka hoʻonui o ka ʻike VA, a lilo i

liʻiliʻi loa ke ʻoi aku ka ʻike o VA ma mua o 25%.

Ua like ka paʻa o ka flexural o EVA me ka PVC palupalu. Hoʻoemi me ka hoʻonui o

VA, Me ka hoʻonui o MI, hoʻemi ka paʻa paʻa.

He launa maikaʻi maikaʻi kā Eva kēpau, hiki ke hoʻohui ʻia me nā kēpau ʻē aʻe e hoʻomaikaʻi

nā waiwai o ke kino. Inā kāwili ʻia ʻo Eva resin a me nitrocellulose, maikaʻi loa ka nitrocellulose f

lexibility, kū'ē i ka hakakā a me ka hoʻopaʻa wela.

Pākuʻi ʻia ʻo PVC paʻa me 5% ~ 10% EVA i hoʻomaikaʻi i ka wai a hoʻomaikaʻi i ka hopena

kūpaʻa. Ua kāwili ʻia ʻo Eva i loko o ka resam Polyamide i ka pale pale pale maikaʻi a me ke kūpaʻa pale

i ka mahana haʻahaʻa.

ʻO Qingdao Sainuo Chemical Co., Ltd. ʻO mākou nā mea hana no ka wax PE, PP wax, OPEwax, EVA

wax, PEMA, EBS, Zinc / Calcium Stearate …. Ua hala kā mākou huahana theREACH, ROHS,
