Pehea e ho'āʻo ai i ka maikaʻi o nā ʻeke EVA?

ʻO ka hōʻike maikaʻi oʻeke EVAHe kaʻina loiloi piha e pili ana i nā ʻano he nui, me nā waiwai kino, nā waiwai kemika, nā kūlana palekana kaiapuni a me nā mea ʻē aʻe. Eia kekahi mau mea ho'āʻo koʻikoʻi a me nā ʻano hana:

1. Hoao hana kino
ʻO ka hoʻāʻo hana kino e loiloi nui i nā waiwai kino kumu o nā ʻeke EVA, me:

ʻO ka ho'āʻo paʻakikī: ʻO ka paʻakikī o nāʻeke EVA e ho'āʻo pinepineʻia e Shore A ho'āʻo paʻakikī, aʻo ka paʻakikī maʻamau ma waena o 30-70

ʻO ka ikaika tensile a me ka elongation i ka haki: ʻO ka ikaika tensile a me ka elongation i ka haki ʻana o ka mea i ana ʻia e ka hoʻāʻo tensile e hōʻike i nā waiwai mechanical a me ka paʻa o ka ʻeke EVA

ʻO ka hoʻāʻo ʻana i ka deformation mau loa: E hoʻoholo i ka hoʻololi mau ʻana o ka mea ma lalo o kahi kaomi e loiloi i ka lōʻihi o ka ʻeke EVA

2. Ho'āʻo hana wela
ʻO ka ho'āʻo hana wela e nānā i ka hana o nāʻeke EVA ma lalo o nā kūlana wela kiʻekiʻe:

Ka helu heheʻe a me ke kūpaʻa wela: ʻO ka helu heheʻe a me ke kūpaʻa wela o nā mea EVA e loiloi ʻia e ka ʻokoʻa scanning calorimetry (DSC) a me ka thermogravimetric analysis (TGA)

Ke kū'ē i ka wela: E ho'āʻo i ke kūʻokoʻa kahiko o nāʻeke EVA i nā wahi wela kiʻekiʻe e hōʻoia i hiki i ka huahana ke mālama i ka hana maikaʻi ma hope o ka hoʻohana lōʻihi.

3. Ke ho'āʻo hana kemika
Loiloi ka ho'āʻo hana kemika i ke kūʻē ʻana o ka ʻeke EVA i nā mea kemika:

ʻO ke kūpaʻa kino kino: loiloi i ke kūʻē ʻana o ka ʻeke EVA i ka waikawa, alkali, paʻakai a me nā mea kemika ʻē aʻe

ʻO ke kūpaʻa ʻaila: hoʻāʻo i ka kūpaʻa a me ka pale ʻana o ka ʻeke EVA i ka ʻaila ʻaila

4. Ho'āʻo kaiapuni adaptability
Nānā ka hoʻāʻo ʻana i ka hiki ʻana o ka ʻeke EVA i nā mea kūlohelohe:

ʻO ka ho'āʻo kū'ē i ka wā:ʻike i ke kū'ēʻana o kaʻeke EVA i nā kukuna ultraviolet, ka haʻahaʻa a me nā loli wela

ʻO ka ho'āʻo kū'ē wela haʻahaʻa: loiloi i ka hana ʻana o ka ʻeke EVA ma ke ʻano wela haʻahaʻa

5. Ka ho'āʻo maʻamau kaiapuni
ʻO ka hoʻāʻo maʻamau kaiapuni e hōʻoia i ka hoʻokō ʻana o ka ʻeke EVA i nā koi kaiapuni a ʻaʻole i loko o nā mea ʻino:

RoHS Directive: Directive e kaupalena ana i ka hoʻohana ʻana i kekahi mau mea pōʻino i ka uila a me ka uila. Pono ka noi ʻana o nā mea EVA i nā lako uila e hoʻokō me kēia kuhikuhi

Hoʻoponopono REACH: Nā hoʻoponopono EU e pili ana i ka hoʻopaʻa inoa, loiloi, ʻae a me ka palena o nā mea kemika. Pono ka hana a me ka hoʻohana ʻana i nā mea EVA e hoʻokō i nā koi o REACH Regulation

6. ʻO ka ho'āʻo ikaika a me ka peel
Nā hoʻāʻo kūikawā no ke kiʻiʻoniʻoni EVA:

ʻO ka hoʻāʻo Transmittance: loiloi i ka transmittance māmā o ka kiʻiʻoniʻoni EVA, he mea nui loa ia no nā noi e like me nā panela lā.

ʻO ka hoʻāʻo ikaika Peel: hoʻāʻo i ka ikaika peel ma waena o ke kiʻi ʻoniʻoni EVA a me ke aniani a me nā mea backplane e hōʻoia i ka hilinaʻi o ka ʻeke.

Ma o nā mea hoʻāʻo i luna, hiki ke loiloi piha ʻia ka maikaʻi o nā pūʻolo EVA e hōʻoia i ka hoʻokō ʻana i nā pono o nā hiʻohiʻona noiʻi like ʻole. I ka hana ʻana a me ka hoʻohana ʻana i nā mea EVA, pono nā ʻoihana e mālama pono i nā kūlana pili honua, aupuni a me nā ʻoihana e hōʻoia i ka maikaʻi o ka huahana a me ka palekana.
