Ka Hoʻohana ʻana a me ka Hoʻomohala ʻana o Polypropylene no ka Thermoforming ma ke Kahua Hoʻopili

1. Nā loina kumu a me nā ʻano o ka thermoforming

ʻO ka Thermoforming kahi ʻano hana plastik kūikawā e hana ai i nā pepa thermoplastic i nā huahana like ʻole. Hoʻomehana ʻia ka pepa thermoplastic e palupalu a laila kaomi ʻia (vacuum a i ʻole kaomi maikaʻi) e hana i ka pepa thermoplastic e hana ma luna o ka ʻili o ka mold e loaʻa ai kahi ʻano e like me ka ʻili o ka mold, a ma hope o ka hoʻomaʻalili ʻana a me ke ʻano, ʻokiʻoki ʻia ka huahana e loaʻa ai ke ʻano i makemake ʻia. He wikiwiki a like ka Thermoforming, me ka manawa pōʻaiapuni molding pōkole a me ke kumukūʻai mold haʻahaʻa, kūpono no ka automation a me ka manawa hana lōʻihi, a ua manaʻo ʻia ʻo ia ke ʻano hana kūpono loa me ke kumukūʻai haʻahaʻa loa ma waena o nā ʻano hana molding plastic. ʻOi aku me ka hoʻomaikaʻi mau ʻana o ke kaʻina hana thermoforming a me nā lako a me ke komo ʻana o ka simulation kamepiula, ua lilo ka thermoforming i ke ʻano hana nui e hoʻokūkū ana me ka injection a me ka blow molding. I nā makahiki i hala iho nei, ua hana ʻia nā holomua hou i nā lako hana thermoforming. Ua hoʻolauna ʻo Jimin i nā lako a me nā kaʻina hana thermoforming i hōʻike ʻia ma K2013 ma Kelemania, kahi i lilo ai ka wikiwiki, ka versatility, ka ʻenehana kaohi a me ka hoʻemi ʻana i ke kumukūʻai i mau kumuhana koʻikoʻi no nā lako hou no ka thermoforming i ka ʻōpala a me ka ʻoihana.

ʻO nā ʻano nui o ka thermoforming: ka hana vacuum, ka hana kaomi, ka hana plunger-assisted a me nā hui pū ʻana o lākou. Nui aʻe nā huahana thermoformed ma ka mākeke, e like me nā kīʻaha, nā pā, nā pā meaʻai, nā mea pāʻani, nā pāpale a me nā mahiole, nā ʻāpana mīkini home a me nā ʻāpana kaʻa, nā ʻāpana hoʻonaninani hale, nā lako kemika, a pēlā aku. Ke hoʻohālikelike ʻia me ka hoʻoheheʻe ʻana i ka injection, loaʻa i ka thermoforming nā pono o ka hana kiʻekiʻe, ka hoʻopukapuka haʻahaʻa i nā lako a me ka hiki ke hana i nā huahana me nā wahi ʻili nui. ʻO nā plastics nui i hoʻohana ʻia i ka thermoforming he polystyrene (PS), polyvinyl chloride (PVC), polyolefins e like me PE, PP, polyacrylates (PMMA) a me ka cellulose e like me nitrocellulose (NC), cellulose acetate (CA), a pēlā aku. Nā plastics ʻenekinia e like meʻacrylonitrile-butadiene-styrene (ABS)hoʻohana ʻia hoʻi. ʻO ka plastik Styrene (ABS), polycarbonate (PC), a pēlā aku. ʻO ka hoʻomohala ʻana o ka PP hana kiʻekiʻe e like me ke aniani kiʻekiʻe, ka ikaika hoʻoheheʻe kiʻekiʻe a me ka warpage haʻahaʻa ua hoʻolaha i ka noi a me ka hoʻomohala ʻana o PP ma ke kahua o ka thermoforming.

2. Ke kūlana o ka mākeke hoʻopili Thermoforming kūloko

Aia ma mua o 3,000 mau ʻoihana hoʻopili thermoforming kūloko, nona ka ʻoi aku ma mua o 300 he hana makahiki ma mua o 1,000 tons. Ma kahi o 70% o nā hale hana me ka hiki ke hana makahiki o nā tausani tons he mau pepa i hana ponoʻī ʻia a me nā mea hoʻohui o nā huahana thermoformed. ʻO PS (OPS) a me polyethylene terephthalate (PET) nā pepa nui i lawe ʻia mai waho, ʻoiai kekahi mau hale hana hiki ke hana i kā lākou mau pepa PP, PS a me PVC ponoʻī a me nā hale hana liʻiliʻi e lawe i kā lākou mau pepa. Hoʻohana nui ʻia nā huahana thermoformed i ka hoʻopili meaʻai, ka hoʻopili ʻole meaʻai a me nā pepa ʻokiʻoki, a ʻokoʻa nā koi no nā mea maka mai kēlā noi a i kēia noi.

3. Ka hoʻomohala ʻana o PP no ka thermoforming

Ua hoʻomaka nā noi thermoforming PP kūloko i nā makahiki 1990 a ua ulu wikiwiki i nā makahiki i hala iho nei, me ka ulu makahiki o kahi o 10%. I kēia manawa, he nui nā mea hana ʻōpala plastik thermoforming nui a kaulana ma Kina, e like me Japan Central Chemical, nāna i kūkulu i nā hale hana ma Kina a hoʻokomo iā lākou i ka hana ʻana, a ʻo kā lākou huahana e kālele nui ʻia ana i nā huahana ʻōpala thermoforming plastic waena a me ke kiʻekiʻe. I kēia manawa, aia ka nele o nā mea PP kūikawā no ke kaʻina hana thermoforming ma Kina. ʻO nā mea hana huahana thermoforming kūloko e kūʻai pinepine iā T30S a me nā resin kumu maʻamau ʻē aʻe i hoʻololi ʻia no ka hoʻohana ʻana, akā ʻo nā huahana i loaʻa ma o ka hoʻololi ʻana ma hope a me ka hana ʻana i nā huahana ʻoihana, aia ka mana hoʻohui like ʻole, ʻaʻole i hoʻokō nā waiwai tensile i nā koi, ʻaʻole like ka mānoanoa o ka paia o ka ipu i ka thermoforming, ka uhi extrusion calendering edge curling a me nā pilikia ʻē aʻe, he paʻakikī ke hoʻokō i ke kūlana kiʻekiʻe a me nā koi kiʻekiʻe o nā koi noi, akā he paʻakikī hoʻi ke hoʻokō i ke koi o ke kūlana kiʻekiʻe a me nā koi kiʻekiʻe, a kaupalena pū i ka pono hana o nā ʻoihana hana ma lalo.

ʻO nā mea hana kūikawā thermoforming ma waho he mau homopolymers ka hapa nui, ʻoi aku ka liʻiliʻi o nā copolymers random aniani, a he lōʻihi nā pōʻaiapuni lawe mai o kekahi mau papa, no laila ʻaʻole hoʻohana pinepine nā mea hana thermoforming kūloko i nā mea i lawe ʻia mai. ʻO ka hana pepa o nā mea hana huahana thermoforming i kēia manawa he 600 mm ka laulā o ka pepa, me ka holomua o ka ʻenehana mīkini hoʻoheheʻe, ke piʻi nei ka laulā o ka pepa, hiki ke ʻoi aku ka laulā ma mua o 1000 mm, no laila hiki i ka pepa ke pale i ka hoʻoheheʻe ʻana ke kau i nā koi kiʻekiʻe. ʻO ka hopena i ka ʻoihana huahana ma lalo, ʻo ia ka hoʻohui ʻana i kahi pakeneka o ka polyethylene kiʻekiʻe-density (PE-HD) i ka PP maʻamau e hoʻomaikaʻi i ke kūpaʻa o ka pepa i ka hoʻoheheʻe ʻana, akā e lawe mai kēia ʻano hana i ka hui like ʻole a me ka palena o ka transparency o nā huahana. Loaʻa i ka ʻoihana thermoforming kūloko kahi koi wikiwiki no nā mea maka PP me ka hana kiʻekiʻe a me ka transparency ultra-kiʻekiʻe.
Ma mua o 2012, ua emi iki ka noiʻi a me ka hoʻomohala ʻana i nā mea thermoforming moakaka kiʻekiʻe ma Kina. I kēlā manawa, ua helu ʻia ke kūlana R&D o nā mea kūikawā thermoforming kūloko ma ka Papa 2.

ʻAʻohe o kēia mau mea kūikawā i hana hou ʻia no ka ikaika hoʻoheheʻe kiʻekiʻe a me ka hoʻolaha kaumaha molekala ākea e pono ai no ka hana thermoforming, a ʻaʻole i hana ʻia kekahi ma kahi pae nui.

I nā makahiki i hala iho nei, ua hoʻomau ʻo Tianjin Petrochemical i ka hoʻomohala ʻana i nā mea kūikawā ma ke kahua o ka PP thermoforming, a ua hoʻokō i nā pono waiwai a me nā pono pili kanaka koʻikoʻi, e hoʻohui ana i ke kala i kēia wahi niche o ka thermoforming.

Hōʻike ka Papa 4 i nā mea PP kūikawā no ka thermoforming i hoʻomohala ʻia e kekahi mau hale hana petrochemical i nā makahiki i hala iho nei, i hoʻomohala ʻia e Shanghai Ru Xia New Material a me kēlā me kēia hale hana petrochemical no nā koi like ʻole ma nā ʻāpana thermoforming like ʻole. Hoʻolaha nui ʻia nā mea hana huahana thermoforming ma lalo, haʻahaʻa ka nui o ka ʻoihana, he kakaikahi nā ʻoihana ma luna o ka unahi, a ua ʻokoʻa ke koi no nā huahana ma lalo, a he mau hoʻolālā ponoʻī ko nā hale hana petrochemical no ka hoʻonohonoho ʻana i ka hana ʻana, no laila aia nō kekahi mau pilikia e hoʻonohonoho pono me ka uka a me ka lalo, akā ʻo ke kuhikuhi hoʻomohala o ka ʻoihana thermoforming ʻo ia ka hana ʻana i nā huahana ma lalo i hoʻokaʻawale ʻia ma kekahi ʻaoʻao, a e hoʻohana i nā mea kūikawā no ka hana ʻana ma ka ʻaoʻao ʻē aʻe, i mea e hoʻomaikaʻi ai i ka maikaʻi o ka huahana a hoʻomaikaʻi i ke kūpaʻa o ka maikaʻi o ka huahana. Ke hoʻohiki nei ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā mea kūikawā no ka thermoforming.
