Nā ʻano hou o ka ʻenehana laminating solvent-free ma nā ʻeke retorting me Aluminum

Ma ke kahua o ka laminating solvent-free, he pilikia paʻakikī ka retorting wela kiʻekiʻe i nā makahiki i hala iho nei. ʻOiai me ka hoʻomohala ʻana o nā lako, nā mea hoʻopili a me nā ʻenehana, ua loaʻa i ka laminating solvent-free no ka plastic me ka plastic ma lalo o 121 ℃ retorting ka nui o ka hoʻohana ʻana i waena o nā mea hana hoʻopili palupalu. Eia kekahi, ke ulu nei ka nui o nā hale hana e hoʻohana ana iā PET/AL, AL/PA a me Plastic/AL no ka 121 ℃ retorting.

E kālele ana kēia pepa i ka hoʻomohala hou loa, nā wahi kaohi i ka wā o ka hana ʻana a me nā ʻano hou o ka wā e hiki mai ana.

1. Ka hoʻomohala hou loa

Ua māhele ʻia nā ʻeke retorting i ʻelua ʻano substrates, plastic/plastic a me plastic/aluminium. Wahi a nā koi GB/T10004-2008, ua hoʻokaʻawale ʻia ke kaʻina hana retorting i ka hapalua-kiʻekiʻe wela (100 ℃ - 121 ℃) a me ke kiʻekiʻe wela (121 ℃ - 145 ℃) ʻelua mau kūlana. I kēia manawa, ua uhi ka laminating solvent-free i ka 121 ℃ a ma lalo o 121 ℃ sterilization treatment.

ʻOkoʻa nā mea i kamaʻāina ʻia ʻo PET, AL, PA, RCPP, i hoʻohana ʻia no nā laminates ʻekolu a ʻehā paha papa, aia kekahi mau mea ʻē aʻe e like me nā kiʻiʻoniʻoni aluminized aniani, retorting PVC ma ka mākeke. ʻOiai ʻaʻohe hana nui a me ka hoʻohana ʻana, pono kēlā mau mea i ka manawa hou a me ka hoʻāʻo hou aku no ka hoʻohana nui ʻana.

I kēia manawa, ua hoʻopili maikaʻi ʻia kā mākou mea hoʻopili WD8262A/B ma ka substrate PET/AL/PA/RCPP, hiki ke piʻi i ka 121℃ retorting. No ka plastic/plastic substrate PA/RCPP, ua hoʻohana nui ʻia kā mākou mea hoʻopili WD8166A/B a ua hoʻomohala ʻia nā hihia.

Ua hoʻoponopono ʻia ke kumu paʻakikī o ka laminating solvent-free, paʻi ʻia ʻo PET/Al e kā mākou WD8262A/B. Ua hana pū mākou me kekahi mau mea hoʻolako lako, hoʻāʻo a hoʻoponopono iā ia no nā tausani manawa, a ua hana hope loa iā WD8262A/B me ka hana maikaʻi. Ma ka moku ʻo Hunan, nui ka hoihoi o kā mākou mea kūʻai aku i nā laminates retorting Aluminium, a ʻoi aku ka maʻalahi iā lākou ke hana i ka hoʻāʻo. No ka substrate PET/AL/RCPP i paʻi ʻia, ua uhi ʻia nā papa āpau me WD8262A/B. No ka paʻi ʻia ʻana o PET/PA/AL/RCPP, hoʻohana ʻia nā papa PET/PA a me AL/RCPP iā WD8262A/B. ʻO ke kaumaha o ka uhi ʻana ma kahi o 1.8 - 2.5 g/m², a ʻo ka wikiwiki ma kahi o 100m/min - 120m/min.

Ua holomua nui nā huahana Kangda solvent-free ma lalo o 128℃ a ke paʻakikī nei no ka 135℃ a hiki i ka 145℃ kiʻekiʻe o ka mālama ʻana i ka wela. Ke noiʻi ʻia nei hoʻi ke kū'ē kemika.

HOʻĀʻO HANA

Nā pilikia:

ʻO ka pilikia nui i ka hana ʻana i nā ʻeke retorting alumini ʻehā papa, ʻo ia ka loaʻa ʻana o ka hui kūpono o nā mea like ʻole, me nā kiʻiʻoniʻoni, nā mea hoʻopili, ka ʻīnika a me ka mea hoʻoheheʻe. ʻOi loa, ʻo ka hana ʻana i ka PET/AL i paʻi piha ʻia i kēia papa waho ka mea paʻakikī loa. Ua kū mākou i kēia mau hihia, i ka wā i lawe ai mākou i nā mea mai nā mea kūʻai aku i kā mākou keʻena hoʻokolohua a hoʻāʻo i nā mea āpau me nā lako, ʻaʻohe hewa i loaʻa. Eia naʻe, i ka wā i hui pū ai mākou i nā mea āpau, ʻaʻole i māʻona ka hana o nā laminates. Aia wale nō ke kāohi piha ʻia nā ʻenehana āpau, nā lako, nā mea, hiki ke hana pono ʻia ka substrate. Hiki i nā hale hana ʻē aʻe ke hana i kēia substrate ʻaʻole ia he manaʻo hiki i kekahi ke hoʻokō i ka holomua.

2. Nā kiko hoʻomalu i ka wā o ka hana ʻana

1) ʻO ke kaumaha o ka uhi ʻana ma kahi o 1.8 - 2.5 g/m².

2) Ka makū a puni

Manaʻo ʻia ka makū o ka lumi e kaohi ma waena o 40% - 70%. E komo ka wai i loko o ka lewa i ka hopena o ka mea hoʻopili, e hōʻemi ka makū kiʻekiʻe i ke kaumaha molekala o ka mea hoʻopili a lawe mai i kekahi mau hopena liʻiliʻi, e hoʻopilikia ana i ka hana o ke kū'ē retorting.

3) Nā hoʻonohonoho ma ka laminator

Wahi a nā mīkini like ʻole, pono e hoʻāʻo ʻia nā hoʻonohonoho kūpono e like me ke kaomi, ke kaomi, a me ka mīkini kāwili e ʻike i kahi noi kūpono a hoʻopalahalaha i nā laminates.

4) Nā koi no nā kiʻiʻoniʻoni

ʻO ke ʻano palahalaha maikaʻi, ka waiwai dyne kūpono, ka emi ʻana a me ka nui o ka wai, a pēlā aku, he mau kūlana pono ia no ka retorting laminating.

3. Nā ʻano o ka wā e hiki mai ana

I kēia manawa, ʻo ka hoʻopili ʻana o ka lamination solvent-free ma luna o ka ʻōpala palupalu, kahi i hoʻokūkū nui ʻia. Ma nā kiko pilikino, aia he 3 mau ala no ka hoʻomohala ʻana i ka lamination solvent-free.

ʻO ka mea mua, hoʻokahi kumu hoʻohālike me nā noi hou aku. Hiki i hoʻokahi huahana ke hana i ka hapa nui o nā substrates o ka mea hana hoʻopili palupalu, hiki ke mālama i ka manawa nui, ka hoʻopili a hoʻonui i ka pono.

ʻO ka lua, ʻoi aku ka hana kiʻekiʻe, kahi e hāʻawi ai i ke kūpaʻa kiʻekiʻe o ka wela a me nā kemika.

ʻO ka mea hope loa, ka palekana o ka meaʻai. I kēia manawa, ʻoi aku ka nui o nā pilikia o ka lamination solvent-free ma mua o ka lamination solvent-base no ka mea he mau kapu kona i nā huahana hana kiʻekiʻe e like me nā ʻeke retorting 135℃.

Ma luna o nā mea a pau, ke ulu wikiwiki nei ka laminating solvent-free, ua puka mai nā ʻenehana hou aʻe. I ka wā e hiki mai ana, hiki i ka laminating solvent-free ke lawe i kahi moʻolelo nui o ka mākeke no ka hoʻopili palupalu a me nā kahua ʻē aʻe.
