ʻO ka ʻokoʻa ma waena o ke kiʻi ʻoniʻoni ʻo PE / PVC / POF

1. Nā wehewehe ʻokoʻa:

ʻO ke kiʻi ʻoniʻoni ʻo PE he mea me ka ʻoʻoleʻa maikaʻi loa, a ʻaʻole maʻalahi e haki me nā mea crusher ea maʻamau. Ma muli o ka palupalu a paʻakikī o ka kiʻi PE, ʻaʻole maʻalahi e ʻokiʻoki, ʻaʻole e hōʻike i ke kiʻekiʻe o ka meahana o ka meahana i ka wikiwiki nui, e hoʻoheheʻe ka LDPE a pili i ka pahi. Hiki ke hoʻokomo pololei ʻia ʻo PE pelletizing i loko o ka port feed o ka extruder i loko o nā ʻāpana, a huki ʻia ke kiʻi ʻoni PE i loko o ka pahu e ka ikaika shear o ka wili e wela ai, hoʻoheheʻe, a hoʻokuʻu aku i ka pelletize. Hiki ke puhi ʻia nā mea papa mua e PE i hiki ke puhi ʻia i ke kiʻi ʻoniʻoni, hoʻohana ʻia no ka ʻaʻai ʻole a me nā lāʻau lapaʻau, a hoʻohana ākea ʻia ia i ka hana o Oxford ʻili a me tarpaulin, me kahi wā e hiki mai ana.

ʻO ka polyvinyl chloride PVC, me nā mea hoʻohui e hoʻonui ai i kona kūpaʻa wela, paʻakikī, ductility, a pēlā aku. ʻO ka papa luna o kēia kiʻi ʻoniʻoni he lacquer, ʻo ka mea nui i waenakonu ʻo polyvinyl chloride, a ʻo ka papa lalo ka laka i uhi ʻia i hope. ʻO ia kahi ʻano synthetic mea i aloha nui ʻia, kaulana a hoʻohana ākea ʻia i ka honua i kēia lā. Ma waena o nā pono e hiki ke hana i nā kiʻi ʻekolu ākea, ʻo PVC ka mea kūpono loa.

POF ʻo ia hoʻi ke kiʻi ʻoniʻoni wela. Kū ʻo POF i ke kiʻina pālua poly extrfined extruded heat shrinkable film. Hoʻohana ia i ka polyethylene haʻahaʻa haʻahaʻa linear e like me ka papa waena (LLDPE) a me ka co-polypropylene (pp) ma ke ʻano o nā papa o loko a me waho. Hoʻopili ʻia ia a huki ʻia i waho o ka mīkini, a laila hana ʻia e nā hana kūikawā e like me ka make ʻana a me ka piʻi ʻana o ke kiʻi ʻoniʻoni.

2. Nā hoʻohana ʻokoʻa:

Hoʻohana ākea ʻo PE heat shrinkable ʻoniʻoni i loko o ka pūʻulu ʻaha holoʻokoʻa o ka waina, kini, wai wai mineral, nā mea inu like ʻole, ka lole a me nā huahana ʻē aʻe. He palupalu maikaʻi ka huahana, hoʻopale i ka hopena a me ke kūpaʻa waimaka, a ʻaʻole maʻalahi e haki a makaʻu hoʻi. Moisture a me ka helu kiʻekiʻe shrinkage.

Ma muli o nā waiwai kūʻokoʻa o PVC (ua-hōʻoia, pale ahi, anti-static, maʻalahi i ke ʻano) a me nā ʻano haʻahaʻa a me nā puka puka kiʻekiʻe o PVC, hoʻohana nui ʻia ia i nā ʻoihana hana hale a me ka ʻūlū hana. No laila, ʻo ka kiʻi ʻoniʻoni PVC kahi kiʻekiʻe transparency, gloss maikaʻi a me ka shrinkage. Nā hiʻohiʻona o ka helu kiʻekiʻe.

ʻO POF kahi ʻano o ke kīwī shrinkable wela, hoʻohana nui ʻia no ka hoʻopili ʻana i nā huahana me nā ʻano maʻamau a me nā kaulike ʻole. Ma muli o kona palekana ʻole ʻona a me ke kaiapuni, transparency high, high shrinkage, maikaʻi heat-sealability, high gloss, paʻakikī, haehae ke kūpale ʻana, Loaʻa iā ia nā hiʻohiʻona o ka shrinkage wela like a kūpono no ka hoʻopili wikiwiki wikiwiki ʻana. He huahana pani ia o nā kiʻi ʻoniʻoni ʻoniʻoni hoʻoluʻu o PVC.

Hoʻohana ākea i nā lako kaʻa, nā huahana ea, nā mea pono, nā puke, nā uila, nā papa kaapuni, MP3, VCD, nā hana lima, nā kiʻi kiʻi a me nā huahana lāʻau ʻē aʻe, nā mea pāʻani, nā pesticides, nā mea e pono ai i kēlā me kēia lā, nā meaʻai, nā mea hoʻonaninani, nā mea inu kēpau, nā huahana waiū, nā lāʻau lapaʻau, Nā huahana e like me cassette a me nā tape wikiō.
