ʻO nā mea kiʻekiʻe o PVC, e emi iho, maʻalahi e haehae, ʻaʻole maʻalahi e haki, ʻaʻole mae, hoʻoponopono nui, hoʻoponopono kala.
Maikaʻi ka paʻi ʻana, maikaʻi ka ʻōlinolino, ʻōlinolino ke kala, a maikaʻi ke kūpaʻa wai.
ʻO nā pāpale wela PVC hiki ke hoʻokō i ka hana kiʻekiʻe, ka pale ʻana i ka wai, ka hoʻohaʻahaʻa kiʻekiʻe, ka paʻakikī kiʻekiʻe, ka waikawa a me ka pale alkali a me nā waiwai kino ʻē aʻe, a maʻalahi ke kaʻina hana, nani i ka helehelena, paʻa paʻa, hiki ke hoʻomaikaʻi i ka waiwai i hoʻohui ʻia o nā huahana pack. , hoʻohana nui ʻia i nā ʻatikala no ka hoʻohana ʻana i kēlā me kēia lā.
Ke kumu hana o ka mea:
ʻO ke kūlana paʻa o ke kaulahao polymer ke ʻano he kūlana wili.Ke wela a hoʻoheheʻe ʻia ka polymer i kahi kūlana elastic nui, hoʻopaneʻe ʻia ke kaulahao polymer a kuhikuhi ʻia ma lalo o ka hana o ka ikaika o waho, a ma hope o ka hōʻea ʻana o ka wikiwiki i ka mahana hoʻololi aniani, ua maloʻo ke kūlana orientation o ke kaulahao polymer.Ke piʻi hou ka mahana, ʻike ʻia ke kaulahao polymer i kahi kūlana paʻa, hiki mai ka wili ʻana, a ma ke ʻano macroscopic, ʻike ʻia ʻo ia ka emi ʻana.
1. He laumania ka ili o ka PVC heat shrinkable film, like me ka mānoanoa a me ka mānoanoa, ʻaʻohe wahi koʻikoʻi, ʻaʻohe ʻaila hinu, haumia, a i ʻole ka pelu ʻana, hiki ke hoʻomaikaʻi i ka maikaʻi o ka hoʻopili huahana.
2. Ma hope o ka emi ʻana o ka pahu, mālama ʻia ia ma lalo o ke kūlana kūlohelohe o 30 degere, a ʻaʻohe hoʻololi kala e like me ka mae a me ka mae.
3. Hiki ke hoʻopaʻa paʻa ʻia ke kiʻi ʻoniʻoni PVC shrink, paʻa, wai ʻole, hoʻomaʻemaʻe, lepo lepo a nani.
ʻO ka PVC heat shrinkable film i nā hiʻohiʻona o ka transparency maikaʻi, ka maʻalahi o ka emi ʻana, ka ikaika kiʻekiʻe, a hiki ke hoʻoponopono ʻia ka helu shrinkage ma ka makemake e like me nā pono o ka mea kūʻai aku.Eia kekahi, maʻalahi loa ka noi, pono wale e hoʻohana i ka ea wela e hoʻopili i ke kiʻi i ka huahana.
ʻO ke kiʻiʻoniʻoni hiki ke hoʻohaʻahaʻa i ka PVC he maikaʻi ke aniani a me ke kiʻekiʻe shrinkage rate, ma waena o 35% a me 45% i ke ala transverse, a he haʻahaʻa kona kumukūʻai, nui ka ikaika tensile, nui ka pae wela, a ʻaʻole kiʻekiʻe nā koi kumu wela. (80-100 ℃), ʻo ke kumu wela wela ka ea wela, infrared a i ʻole ka hui pū ʻana o nā mea ʻelua.
