Panehana ʻia nā ʻeke me nā mea kiʻi ʻoniʻoni lahilahi, i hoʻomaloʻo ʻia a i ʻole co extruded e hana i kahi ʻeke nui. Hiki ke hoʻokaʻawale ʻia nā mea haku mele i 9 mau ʻano, a me kapane akuʻeke i hana ʻia e hiki ke kū i ka wela kiʻekiʻe a me ka sterilization wela maʻemaʻe. Pono hoʻi kona hoʻolālā hoʻolālā e hoʻokō i nā koi o ka hoʻopaʻa ʻana i ka wela maikaʻi, ka pale ʻana i ka wela, ke kūpaʻa wai, ka ikaika kiʻekiʻe, a me ka hana pale kiʻekiʻe.
1. PET kiʻiʻoniʻoni
Hana ʻia ke kiʻi ʻoniʻoni BOPET ma ka hoʻokuʻu ʻana i ka resin PET ma o ke kiʻi T a me ka biaxially stretching, nona nā waiwai maikaʻi loa.
(1) Hana maikaʻi ka mīkini. ʻO ka ikaika tensile o BOPET kiʻiʻoniʻoni ka mea kiʻekiʻe loa ma waena o nā kiʻiʻoniʻoni plastik āpau, a hiki i nā huahana lahilahi ke hoʻokō i nā pono, me ka rigidity ikaika a me ka paʻakikī kiʻekiʻe.
(2) Kūleʻa maikaʻi loa i ke anu a me ka wela. ʻO ka pae wela kūpono o ka kiʻiʻoniʻoni BOPET mai 70 a 150 ℃, e mālama ana i nā waiwai kino maikaʻi ma luna o kahi ākea ākea, kūpono ia no ka hapa nui o ka ʻeke huahana.
(3) Hana maikaʻi i ka pale. Loaʻa iā ia ka maikaʻi o ka wai a me ka hoʻokō ʻana i ke kinoea, ʻaʻole like me ka nylon, i hoʻopilikia nui ʻia e ka haʻahaʻa. Ua like kona wai kū'ē i ka PE, a he li'ili'i loa kona heluna permeability. He pale kiʻekiʻe kona i ka ea a me ka ʻala, a ʻo ia kekahi o nā mea mālama ʻala.
(4) Ke kū'ē kemika, kaʻaila kū'ē, a me ka hapa nui o nā mea hoʻoheheʻe, dilute acids, dilute alkalis, etc.
2. BOPA kiʻiʻoniʻoni
ʻO ke kiʻi ʻoniʻoni BOPA he kiʻi ʻoniʻoni biaxial stretching, hiki ke loaʻa ma ka puhi ʻana a me ka biaxial stretching i ka manawa like. Hiki ke hoʻolōʻihi ʻia ke kiʻiʻoniʻoni biaxially me ka hoʻohana ʻana i ke ʻano T-mold extrusion, a i ʻole biaxially i ka manawa like me ka hoʻohana ʻana i ke ʻano hoʻoheheʻe ʻana. ʻO nā hiʻohiʻona o ka kiʻiʻoniʻoni BOPA penei:
(1) Oolea maikai loa. ʻO ka ikaika tensile, ka ikaika o ka waimaka, ka ikaika o ka hopena, a me ka ikaika o ka haki ʻana o ka kiʻiʻoniʻoni BOPA i waena o nā mea maikaʻi loa ma waena o nā mea plastik.
(2) ʻO ka hoʻololi maikaʻi loa, ke kū ʻana o ka puka nila, a me ka paʻakikī i ke kiko ʻana i nā mea i loko, he hiʻohiʻona nui o BOPA, me ka maʻalahi maikaʻi a me ka manaʻo paʻa maikaʻi.
(3) ʻO nā waiwai pale maikaʻi, mālama ʻia ka ʻala maikaʻi, kūpaʻa maikaʻi i nā kemika ʻē aʻe ma mua o nā waikawa ikaika, ʻoi aku ka pale ʻana i ka aila.
(4) He ākea ka laulā wela, me kahi helu heheʻe o 225 ℃, a hiki ke hoʻohana no ka manawa lōʻihi ma waena o -60 ~ 130 ℃. Noho paʻa nā waiwai mechanical o BOPA i nā mahana haʻahaʻa a kiʻekiʻe.
(5) Hoʻopilikia nui ʻia ka hana o ka kiʻiʻoniʻoni BOPA e ka haʻahaʻa, ʻoi aku ka nui o ke kūpaʻa dimensional a me nā waiwai pale. Ma hope o ka pulupulu ʻana, hoʻolōʻihi ʻia ke kiʻi ʻoniʻoni BOPA ma ka ʻaoʻao, koe wale ka wrinkling. ʻO ka pōkole lōʻihi, me ka elongation kiʻekiʻe o 1%.
3. CPP kiʻiʻoniʻoni
ʻO ke kiʻiʻoniʻoni CPP, ʻike ʻia hoʻi he kiʻiʻoniʻoni polypropylene cast, he kiʻiʻoniʻoni polypropylene non-strenged, nonoriented polypropylene film. Hoʻokaʻawale ʻia i homopolymer CPP a me copolymer CPP e like me nā mea maka. ʻO ka mea maka nui no ke kiʻi ʻoniʻoni CPP papa ʻaina he block copolymer impact resistant polypropylene. ʻO nā koi o ka hana: ʻoi aku ka kiʻekiʻe o ka mahana palupalu o Vicat ma mua o ka mahana kuke, ʻoi aku ka maikaʻi o ka hopena, ʻoi aku ka maikaʻi o ke kūpaʻa waena, a ʻoi aku ka liʻiliʻi o ka maka iʻa a me ke kiko aniani.
4. Aluminum pepa
ʻO ka alumini alumini wale nō ke ʻano o ka metala i loko o nā mea hoʻopili palupalu, hoʻohana ʻia no nā mea hoʻopili me kahi manawa noi lōʻihi. ʻO ka pahu alumini ka mea metala me ka wai kū ʻole i ka wai, ke kūpaʻa kinoea, ka pale māmā, a me nā waiwai paʻa i ka ʻono i hoʻohālikelike ʻia me nā mea hoʻopili ʻē aʻe. He mea paʻi ʻaʻole hiki ke hoʻololi piha ʻia a hiki i kēia lā.
5. ʻO ka uhi hoʻoheheʻe ceramic
He ʻano kiʻi ʻoniʻoni hou ʻo Ceramic vapor coating, i loaʻa ma ka vaporizing metala oxides ma luna o ka ʻili o ka kiʻiʻoniʻoni plastik a i ʻole ka pepa e like me ka substrate i nā mea hana kiʻekiʻe. ʻO nā hiʻohiʻona o ka uhi ʻana o ka ceramic vapor ka mea nui:
(1) Hana maikaʻi loa, kokoke e hoʻohālikelike ʻia me nā mea alumini foil composite.
(2) Maikaʻi ʻike, microwave permeability, kiʻekiʻe wela ke kūpaʻa, kūpono no ka meaʻai microwave.
(3) Paʻa ʻala maikaʻi. Ua like ka hopena me ka pahu aniani, ʻaʻole ia e hoʻopuka i kekahi ʻala ma hope o ka mālama ʻana i ka wā lōʻihi a i ʻole ka mālama ʻana i ka wela kiʻekiʻe.
(4) Aloha kaiapuni maikaʻi. ʻO ka wela wela haʻahaʻa a me ke koena liʻiliʻi ma hope o ka puhi ʻana.
6. Nā kiʻi ʻoniʻoni lahilahi ʻē aʻe
(1) PEN kiʻiʻoniʻoni
Ua like ke ano o ka PEN me PET, a he mau ano like ole kona o ka PET, a aneane ua oi aku kona mau waiwai a pau mamua o PET. Hana maikaʻi loa, ikaika kiʻekiʻe, kūpaʻa wela maikaʻi, hana pale maikaʻi, a me ka ʻike. ʻO ke kūpaʻa UV koʻikoʻi ka mea nui loa o PEN. He 3.5 manawa ka pale o PEN i ka mahu wai ma mua o ko PET, a o kona pale i na kinoea like ole he eha ia mamua o ko PET.
(2) kiʻiʻoniʻoni BOPI
Loaʻa i ka BOPI kahi ākea ākea ākea, mai -269 a 400 ℃. ʻO ke kiʻiʻoniʻoni i hoʻopau i ka hopena ʻaʻohe wahi heheʻe, a ʻo ka mahana hoʻololi aniani ma waena o 360 a 410 ℃. Hiki ke hoʻohana mau ʻia i ka ea ma 250 ℃ no nā makahiki ʻoi aku ma mua o 15 me ka ʻole o nā loli hana nui. Loaʻa i ka BOPI nā hana piha maikaʻi loa, nā waiwai kino a me nā mechanical kiʻekiʻe, ka pale ʻana i ka radiation, ka pale ʻana i ka solvent kemika, ke kūpaʻa dimensional, a me ka maʻalahi a me ka pale pale.
(3) PBT kiʻiʻoniʻoni
ʻO ke kiʻi ʻoniʻoni PBT kekahi o nā kiʻiʻoniʻoni polyester thermoplastic, ʻo ia hoʻi ke kiʻi butylene terephthalate. ʻO ka Density ka 1.31-1.34g / cm ³ ， ʻO ka helu hoʻoheheʻe he 225 ~ 228 ℃, a ʻo ka mahana hoʻololi aniani he 22 ~ 25 ℃. ʻOi aku ka maikaʻi o ke kiʻi ʻoniʻoni PBT ma mua o ka kiʻiʻoniʻoni PET. ʻO ka PBT he pale wela maikaʻi loa, ke kūpaʻa aila, ka mālama ʻana i ka ʻala, a me nā waiwai hoʻopaʻa wela, e kūpono ana i nā ʻeke ʻeke i hoʻohana ʻia i ka hana ʻana i ka meaʻai microwave. Hiki ke hoʻohana ʻia ke kiʻi ʻoniʻoni PBT no ka hoʻopili ʻana i ka meaʻai ʻono. ʻO ke kiʻiʻoniʻoni PBT he kūʻē kemika maikaʻi loa.
(4) kiʻiʻoniʻoni TPX
Hoʻokumu ʻia ka kiʻiʻoniʻoni TPX e ka copolymerization o 4-methylpentene-1 me kahi liʻiliʻi o 2-olefin (3% ~ 5%), a ʻo ia ka ʻilika māmā loa me ka umekaumaha kikoʻī o 0.83g/cm ³ wale nō, ʻoi aku ka maikaʻi o nā hana ʻē aʻe. maikaʻi loa. Eia kekahi, ʻoi aku ka maikaʻi o ka pale wela o TPX a ʻo ia ka mea wela loa i waena o nā polyolefins. Loaʻa iā ia kahi helu hoʻoheheʻe crystallization o 235 ℃, nā waiwai mechanical maikaʻi, modulus tensile kiʻekiʻe a me ka elongation haʻahaʻa, kūpaʻa kemika ikaika, kūpaʻa aila, kūpaʻa kiʻekiʻe i ka waikawa, alkali, a me ka wai, a me ke kū'ē i ka hapa nui o nā hydrocarbons. Hiki iā ia ke kūpaʻa i nā wela wela a hiki i 60 ℃, ʻoi aku ma mua o nā plastic plastic ʻē aʻe. Loaʻa iā ia ka transparency kiʻekiʻe a me ka transmittance o 98%. ʻO kona hiʻohiʻona he aniani aniani, hoʻonani, a he ikaika ke komo ʻana i ka microwave.
Inā loaʻa iā ʻoe nā koi retort pouch, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou. Ma ke ʻano he mea hana hoʻopihapiha maʻalahi ma mua o 20 mau makahiki, e hāʻawi mākou i kāu mau hoʻonā hoʻopihapiha kūpono e like me kāu pono huahana a me kāu kālā.
