"Hoʻohana ʻia ka polypropylene mai ka polymerization o ke kinoea ma hope o ke kiʻekiʻe o ka wela o ka ʻaila ma lalo o ka hana a nā catalysts, e like me nā ʻano hana kiʻi ʻoniʻoni ʻē aʻe e hiki ke loaʻa mai nā kiʻiʻoniʻoni hana like ʻole, hoʻohana maʻamau ʻo BOPP maʻamau, matte BOPP, kiʻi momi, ʻO BOPP i hoʻopaʻa ʻia me ka wela, hoʻolei CPP, puhi ʻana i ka IPP, etc.
1, kiʻiʻoniʻoni BOPP kumu nui
Hoʻopili ʻia ke kiʻi ʻoniʻoni BOPP i mea e hohola ʻia ai ka ʻāpana amorphous a i ʻole ka ʻāpana o ke kiʻi crystalline ma nā ʻaoʻao longitudinal a transverse ma luna o ka wahi palupalu, i hoʻonui ʻia ka ʻili o ke kiʻiʻoniʻoni, hoʻemi ʻia ka mānoanoa, a hoʻomaikaʻi maikaʻi ʻia ka nani a me ka ʻike. I ka manawa like, hoʻomaikaʻi maikaʻi ʻia ka ikaika mechanical, ka paʻa ʻana o ka ea, ka pale ʻana a me ke kū anuanu ma muli o ke ʻano o nā molekala i hoʻolahalaha ʻia.
Nā waiwai o ka kiʻiʻoniʻoni BOPP:
Ka ikaika tensile kiʻekiʻe, modulus kiʻekiʻe o ka elasticity, akā ikaika haʻahaʻa haʻahaʻa; ʻo ka rigidity maikaʻi, ka elongation maikaʻi a me ke kū'ē i ka hana luhi luhi; kiʻekiʻe ka wela a me ke anuanu, ka hoʻohana ʻana i ka mahana a hiki i 120 ℃, ʻoi aku ka kiʻekiʻe o ka pale anuanu BOPP ma mua o ka kiʻiʻoniʻoni PP maʻamau; kiʻekiʻe kiʻekiʻe gloss gloss, maikaʻi akaka, kūpono no nā ʻano mea hoʻopihapiha; He maikaʻi ke kūpaʻa kemika BOPP, ma waho aʻe o nā ʻakika ikaika, e like me ka fuming sulfuric acid, ʻo ka nitric acid ka hopena corrosive ma luna o ia mea Eia kekahi, ʻaʻole hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe ʻē aʻe, a ʻo kekahi mau hydrocarbons wale nō ka hopena o ka pehu; ʻoi aku ka maikaʻi o ka wai, ʻo ia kekahi o nā mea maikaʻi loa no ka makū a me ka pale ʻana i ka wai, ka nui o ka hoʻoheheʻe wai <0.01%; maikaʻi ʻole ka paʻi ʻana, no laila pono e mālama ʻia ka ʻili ma mua o ka paʻi ʻana, ka hopena paʻi maikaʻi ma hope o ka hana ʻana; ka uila static kiʻekiʻe, pono e hoʻohui ʻia ka resin i hoʻohana ʻia i ka hana kiʻiʻoniʻoni i ka mea antistatic agent.
2、Matte BOPP
Hoʻolālā ʻia ka ʻili o ka matte BOPP ma ke ʻano he papa matte, kahi e hana ai i ke ʻano o ke ʻano e like me ka pepa a ʻoluʻolu i ka paʻi. ʻAʻole hoʻohana ʻia ka papa ʻili matte no ka hoʻopaʻa ʻana i ka wela, ma muli o ke ʻano o ka papa matte, i hoʻohālikelike ʻia me ka BOPP kumu nui, loaʻa nā ʻano penei: hiki i ka papa ʻili matte ke pāʻani i kahi hana pale, ua hoʻemi nui ʻia ka ʻili o ka ʻili; Hiki ke hoʻohana ʻia ka papa matte no ka hoʻopaʻa ʻana i ka wela inā pono; He laumania a maikaʻi ka papa ʻili matte, no ka mea, ʻaʻole maʻalahi ka paʻa ʻana o ka ʻili me ka anti-adhesive; ʻOi aku ka haʻahaʻa o ka ikaika tensile film matte ma mua o ke kiʻiʻoniʻoni maʻamau, kapa ʻia ke kūpaʻa wela i ka BOPP maʻamau.
3、Pearlescent film
Hana ʻia ka kiʻiʻoniʻoni momi me PP, CaCO3, ka puaʻa pearlescent a me ka hoʻololi ʻana i ka puʻupuʻu i hoʻohui ʻia a hui pū ʻia me ka hoʻolōʻihi ʻana i ka bi-directional. E like me ka hohola ʻana o nā molekala resin PP i ka wā o ke kaʻina hana biaxial, a ua hoʻokaʻawale ʻia nā ʻāpana CaCO3 mai kekahi i kekahi, pēlā e hana ai i nā pore bubbles, no laila, ʻo ka pearlescent film he microporous foam film me ka density a puni 0.7g/cm³.
Nalo ka mole PP i kona sealability wela ma hope o ka biaxial orientation, akā loaʻa nō kekahi mau sealability wela e like me ka lāʻau a me nā mea hoʻololi ʻē aʻe, akā haʻahaʻa loa ka ikaika seal wela a maʻalahi hoʻi e haehae, i hoʻohana pinepine ʻia i loko o ka ʻeke o ka ice cream, popsicle, etc.
4、Heat sealing BOPP kiʻiʻoniʻoni
Kiʻiʻoniʻoni wela ʻaoʻao ʻelua:
ʻO kēia kiʻiʻoniʻoni he ʻano ABC, ʻaoʻao A a me C no ka pae sila wela. Hoʻohana nui ʻia e like me nā mea hoʻopihapiha no ka meaʻai, textiles, nā leo a me nā huahana wikiō, etc.
Hoʻokahi ʻaoʻao wela sila kiʻiʻoniʻoni:
ʻO kēia ʻano kiʻiʻoniʻoni ʻo ia ka hoʻolālā ABB, me kahi papa e like me ka papa hoʻopaʻa wela. Ma hope o ka paʻi ʻana i nā hiʻohiʻona ma ka ʻaoʻao B, ua hoʻopaʻa ʻia me ka PE, BOPP a me ka alumini foil e hana i nā ʻeke, i hoʻohana ʻia e like me nā mea hoʻopihapiha kiʻekiʻe no ka meaʻai, nā mea inu, ke kī, etc.
5, kiʻiʻoniʻoni CPP hoʻopaneʻe kahe
ʻO ke kiʻiʻoniʻoni polypropylene CPP he kiʻiʻoniʻoni polypropylene non-stretch, non-directional polypropylene film.
Hōʻike ʻia ke kiʻi ʻoniʻoni CPP e ke aniani kiʻekiʻe, ka palahalaha maikaʻi, ke kūpaʻa kiʻekiʻe kiʻekiʻe, ke ʻano o ka maʻalahi me ka ʻole o ka nalowale ʻana, nā waiwai sealing wela maikaʻi. Loaʻa i ka Homopolymer CPP kahi pānaʻi liʻiliʻi o ka wela sealing wela a me ka brittleness kiʻekiʻe, e kūpono ia no ka hoʻohana ʻana ma ke ʻano he kiʻi ʻoniʻoni hoʻokahi.
He hana kaulike ko Co-polymer CPP a ua kūpono ʻo ia e like me ka papa o loko o ke kiʻi ʻoniʻoni. I kēia manawa, hui pū ʻia ka CPP nui, hiki ke hoʻohana piha i nā ʻano polypropylene like ʻole o ka hui ʻana, e hoʻonui i ka hana CPP.
6. Kiʻiʻoniʻoni IPP i puhi ʻia
Hoʻopuka pinepine ʻia ke kiʻi ʻoniʻoni IPP ma ke ala hoʻohaʻahaʻa, hoʻoheheʻe ʻia ʻo PP a puhi ʻia i loko o ka waha o ke apo, ma hope koke o ka hoʻoluʻu mua ʻana e ke apo makani, i hana ʻia e ka wai hoʻoheheʻe pilikia, maloʻo a ʻōwili ʻia, ʻo ka huahana i hoʻopau ʻia he kiʻi ʻoniʻoni. hiki ke ʻoki ʻia e lilo i pepa kiʻiʻoniʻoni. He maikaʻi ka ʻike ʻana o Blown IPP, ʻo ka rigidity maikaʻi a me ka hana ʻeke maʻalahi, akā ʻilihune kona mānoanoa like ʻole a ʻaʻole maikaʻi ka palahalaha kiʻiʻoniʻoni.
