1. He aha nā inoa o ka kiʻiʻoniʻoni CPP, kiʻiʻoniʻoni OPP, kiʻiʻoniʻoni BOPP, a me ke kiʻiʻoniʻoni MOPP?
2. No ke aha e pono ai ke kikoo ʻia ke kiʻiʻoniʻoni?
3. He aha ka ʻokoʻa ma waena o ka kiʻiʻoniʻoni PP a me ke kiʻi ʻoniʻoni OPP?
4. Pehea ka ʻokoʻa ma waena o OPPkiʻiʻoniʻoni a me CPPkiʻiʻoniʻoni?
5. He aha nā ʻokoʻa ma waena o ke kiʻi ʻoniʻoni OPP, kiʻiʻoniʻoni BOPP, a me ke kiʻiʻoniʻoni MOPP?
1. He aha nā inoa o ka kiʻiʻoniʻoni CPP, kiʻiʻoniʻoni OPP, kiʻiʻoniʻoni BOPP, a me ke kiʻiʻoniʻoni MOPP?
ʻO ka kiʻi PP e pili ana i ka huaʻōlelo maʻamau no "polypropylene film", Ma ka hoʻohana ʻana i nā ʻano hana like ʻole, hana ʻia nā kiʻiʻoniʻoni PP me nā ʻano like ʻole, A hoʻohana ʻia i nā kahua like ʻole, a hoʻonui ʻia i nā inoa ʻē aʻe, ʻO nā inoa maʻamau:CPPkiʻiʻoniʻoni, OPPkiʻiʻoniʻoni, BOPPkiʻiʻoniʻoni, MOPPkiʻiʻoniʻoni, Hana ʻia kēia mau inoa ʻehā me ka kiʻiʻoniʻoni PP, ka mea i hana ʻia me ka hoʻohana ʻana i nā mea palaka PP ma o nā mīkini extrusion,Ua ulu aʻe nā inoa like ʻole ma o nā kaʻina hana "film stretching".
ʻO ka mea i kaha ʻia ma ka ʻulaʻula e hōʻike ana i nā ʻokoʻa o ke "ʻano hoʻololo kiʻiʻoniʻoni"
1. C PP kiʻiʻoniʻoni: abbreviation forC ast Polypropylene,
ʻO ka huaʻōlelo "hoolei kiʻiʻoniʻoni polypropylene" e pili ana i kahi kiʻi ʻoniʻoni ʻole,pili ole kiʻiʻoniʻoni extruded palahalaha.
2. OPP kiʻiʻoniʻoni: Abbreviation forKūleʻa Polypropylene,
ʻO ia hoʻi, 'unidirectional stretchingo polypropylene film', ma kaTD kuhikuhi o ka hohola unidirectional.
3. BO PP kiʻiʻoniʻoni: abbreviation forKūlana BiaxiallyPolypropylene,
ʻO ia hoʻi "kālua ʻia kiʻiʻoniʻoni polypropylene", e hohola ana i loko o kaNā kuhikuhi MD a me TD.
4. MO PP kiʻiʻoniʻoni: abbreviation forMonoaxially OrientedPolypropylene,
ʻO ia hoʻi, 'unidirectional stretched polypropylene film', unidirectional kikoo i loko o kaMD kuhikuhi.
▶MD kuhikuhi: E pili ana i kaMachineDirection, ʻo ia ke kuhikuhi lōʻihi o ke kiʻiʻoniʻoni.
▶TD kuhikuhi: E pili ana i kaTranverseDidirection o ke kii.
2.No ke aha e pono ai ke kikoo ʻia ke kiʻiʻoniʻoni?
ʻO ka maʻamau, ke kumu e pono ai ke kiʻi ʻoniʻoni "stretched" no kēia mau kumu:
1. Hoʻomaikaʻi i ke kūpaʻa dimensional.
2. E hoʻomaikaʻi i nā waiwai mechanical.
3. E hoʻomaikaʻi i ka glossiness a me ka ʻike.
4. E hoʻomaikaʻi i ka pale ʻana i ka ea.
ʻO nā kumu ʻehā ma luna nei ke kumu e pono ai ke kikoo ʻia ke kiʻiʻoniʻoni,Ma muli o ke kau ʻana o ka polymer, hiki iā ia ke hoʻonohonoho i ke kuhikuhi ʻana o ka polymer i ke ʻano maʻamau, e hoʻoulu i kahi kiʻekiʻe o ka hoʻohui ʻana, hoʻomaikaʻi i ka nui o ka waiwai a me ka ikaika kiʻiʻoniʻoni,hoʻonui i ka pale kinoea, hoʻomaikaʻi i nā waiwai mechanical, a hoʻonui i ka nani o ka ʻili a me ka ʻike.
3.He aha ka ʻokoʻa ma waena o ka kiʻiʻoniʻoni PP a me ke kiʻi ʻoniʻoni OPP?
ʻO ka kiʻiʻoniʻoni PP e pili ana i ka kiʻi polypropylene, a ʻo ka mea maʻamau i kapa ʻia i ka kiʻiʻoniʻoni PP he kiʻi ʻoniʻoni ʻo CPP, kiʻi ʻoniʻoni BOPP, a i ʻole kiʻi ʻoniʻoni PP hana (PP pale kiʻi ʻoniʻoni, PP luminous film, PP composite material film), no laila he huaʻōlelo ākea ʻo PP.
ʻO ka ʻoiaʻiʻo, aia paha nā kiʻiʻoniʻoni PP me nā hana like ʻole a i ʻole nā kaʻina hoʻolōʻihi.
ʻO ke kiʻi ʻoniʻoni OPP kahi huahana kiʻiʻoniʻoni ʻoniʻoni e hoʻohana ana i kahi "unidirectional stretching method" ma PP film, e ʻae ana i ka kiʻiʻoniʻoni e hoʻonui i ke kuhikuhi TD, e hopena i ka ikaika tensile maikaʻi, glossiness, gas resistance, etc. a i ʻole ka lipine aniani.
<Ka hopena>
ʻO nā mea maka no ka kiʻi PP a me ke kiʻi OPP he polypropylene,
ʻO ka kiʻi PP he huaʻōlelo maʻamau no ka kiʻiʻoniʻoni polypropylene,
Ma hope o ka hohola ʻana i ke kiʻi PP ma o ka mīkini hoʻonui TDO, hana ʻia kahi kiʻiʻoniʻoni OPP,
A hoʻonui ke kiʻi ʻoniʻoni OPP i nā waiwai mechanical, kūpono ia no ka hoʻohana ʻana e like me nā ʻeke ʻeke a me nā lipine adhesive.
4. Pehea ka ʻokoʻa ma waena o ke kiʻi ʻoniʻoni OPP a me ke kiʻi CPP?
ʻIke ʻia ka kiʻiʻoniʻoni CPP he polypropylene cast, ʻike ʻia hoʻi he kiʻiʻoniʻoni polypropylene unstretched.
Hoʻoheheʻe ʻia ka plastic i loko o ka mea maka ma o ka extruder, hoʻokuʻu ʻia ma o ka mold hoʻoheheʻe ʻana i ke ʻano T, e kahe ana ma kahi ʻano pepa ma luna o kahi huila hoʻoheheʻe anuanu no ka hoʻoluʻu wikiwiki ʻana, a laila huki, ʻoki ʻia, a ʻōwili ʻia e hoʻopiha i ka huahana.
Ma muli o kēia kaʻina hana, loaʻa i nā membrane CPP kekahi mau hiʻohiʻona:
-ʻOi aku ka paʻakikī ma mua o ka kiʻiʻoniʻoni PE.
-Ka pale maikaʻi no ka makū a me ka ʻala.
- Hoʻohui like ʻia e hana i nā membrane hana hou aku.
-ʻAʻole hoʻohana ʻia nā mea hoʻoheheʻe i ka wā o ke kaʻina hana, kahi mea pili i ke kaiapuni.
-Me ka māmā, ka ikaika kiʻekiʻe, ka paʻakikī kiʻekiʻe, a me ke kūpaʻa hopena maikaʻi loa, ʻo ia ka mea i koho ʻia no nā mea hana.
<Ka hopena>
ʻO ka ʻokoʻa nui loa ma waena o ka kiʻiʻoniʻoni CPP a me ka kiʻiʻoniʻoni OPP ʻo ia ke kikoo a ʻaʻole paha. Hoʻohana ʻo OPP i ka ʻenehana kikoʻī e hoʻomaikaʻi i ka hana o ke kiʻiʻoniʻoni. ʻOiai ʻaʻole kikoo ʻia ke kiʻiʻoniʻoni CPP, hiki ke hoʻoponopono ʻia ke ʻano e like me nā pono o ka mea kūʻai aku, e hoʻonui i kāna noi a hoʻololi hou.
No ka laʻana, hoʻololi i ka waihoʻoluʻu, ka ʻili o ka noe, ka ʻili kukui, ka anti fog, ka paʻi ʻana, a me nā mea ʻē aʻe o ke kiʻiʻoniʻoni Hiki ke hana ʻia nā kiʻiʻoniʻoni PP hana like ʻole ma o nā ʻano like ʻole.
5. He aha nā ʻokoʻa ma waena o ke kiʻi ʻoniʻoni OPP, kiʻi ʻoniʻoni BOPP, a me ka kiʻiʻoniʻoni MOPP?
BOPP kiʻiʻoniʻoni he kiʻiʻoniʻoni polypropylene biaxially
Kiʻiʻoniʻoni OPP he kiʻiʻoniʻoni polypropylene Laterally stretched
Kiʻiʻoniʻoni MOPP he kiʻiʻoniʻoni polypropylene lōʻihi
E kūkākūkā mākou me nā nīnau i nīnau pinepine ʻia o "OPP film vs. BOPP film" a me "OPP film vs. MOPP film":
a. He aha ka ʻokoʻa ma waena o ke kiʻi ʻoniʻoni OPP a me ka kiʻiʻoniʻoni BOPP?
ʻAʻole ʻokoʻa loa nā ʻano kino a me nā hiʻohiʻona o nā membrane OPP a me BOPP ma lalo o nā kūlana hoʻohana maoli, a mālama ʻia lākou e like me ka membrane like. Ke hana ʻia nei ka OPP e kahi extruder, ua hoʻolōʻihi ʻia ka membrane i ka longitudinally (MD direction) i ka wā o ke kaʻina hana.aa laila ma ka ʻaoʻao (TD direction) e kekahi mīkini hoʻonui. ʻO ke kaʻina holoʻokoʻa ma ke ʻano o ka "biaxial stretching", no laila ua like nā hopena me ka BOPP membrane biaxial stretching me ka hoʻohana ʻana i ka mīkini hoʻonui biaxial, No laila, ʻaʻohe ʻokoʻa nui i nā ʻano ma waena o ke kiʻi ʻoniʻoni OPP a me ke kiʻi BOPP.
ʻO nā ʻano o ka unidirectional stretching a me ka biaxial stretching, inā hoʻohana ʻia i nā mea PET a i ʻole PC, e hana i nā ʻano like ʻole,
He ʻokoʻa koʻikoʻi ma ka hana optical a i ʻole ka helu refractive ma waena o PET a me BOPET. Akā ke hoʻohana ʻia ma ka kiʻiʻoniʻoni PP, liʻiliʻi ka ʻokoʻa.
b. He aha ka ʻokoʻa ma waena o ke kiʻi ʻoniʻoni OPP a me ka kiʻiʻoniʻoni MOPP?
Hoʻonui ʻia ke kiʻi ʻoniʻoni OPP "Laterally of thekiʻiʻoniʻoni", oiai MOPP kiʻiʻoniʻoni hoʻonui "longitudinally o kafim". Ke hoʻolōʻihi ʻia ke kiʻi ʻoniʻoni MOPP i ka longitudinally, hohola ia i ka "clockwise" o ke kaulahao mole, no laila ikaika ka ikaika tensile longitudinal, akā nāwaliwali ka ikaika tensile transverse, e maʻalahi ai ka haki.
ʻO ke kiʻiʻoniʻoni OPP, ma muli o kāna mau waiwai like me ka BOPP kiʻi i ʻōlelo ʻia ma luna, ʻaʻole hiki ke haʻihaʻi ma nā ʻaoʻao longitudinal a me ka transverse a loaʻa ka ikaika tensile kumu.
<Ka hopena>
a. He aha ka ʻokoʻa ma waena o ke kiʻi ʻoniʻoni OPP a me ka kiʻiʻoniʻoni BOPP?
Mai ka hiʻohiʻona o nā ʻenehana hana, nā huahana ʻelua i hana ʻia e nā ʻenehana like ʻole.
Mai ka hiʻohiʻona o ka noi, ua manaʻo ʻia nā huahana ʻelua no ka mea liʻiliʻi loa nā ʻokoʻa o nā ʻano.
b. He aha ka ʻokoʻa ma waena o ke kiʻi ʻoniʻoni OPP a me ka kiʻiʻoniʻoni MOPP?
Ka ikaika tensile longitudinal o ka membrane: MOPP membrane>OPP membrane
No laila, kūpono ke kiʻi MOPP no nā noi me nā waiwai unidirectional a me ka ikaika tensile kiʻekiʻe.
Loaʻa i ke kiʻi ʻoniʻoni OPP kekahi ikaika tensile kumu ma nā ʻaoʻao longitudinal a me ka transverse.
ʻO ka mea i luna nei he hōʻuluʻulu a kaʻana like i nā palapala pūnaewele, Inā loaʻa iā ʻoe nā koi kūʻai no ka kiʻiʻoniʻoni CPP, kiʻi ʻoniʻoni OPP, kiʻiʻoniʻoni BOPP, kiʻiʻoniʻoni MOPP, e ʻoluʻolu e kelepona mai iā mākou:
