Nā ʻano hou o ka ʻenehana laminating solvent-free ma ka hoʻihoʻi ʻana i nā ʻeke me ka Aluminum

Ma ke kahua o ka solvent-free laminating, he pilikia paʻakikī ka hoʻihoʻi ʻana i ka wela i nā makahiki i hala.ʻOiai me ka hoʻomohala ʻana i nā mea hana, nā mea hoʻopili a me nā ʻenehana, ka laminating solvent-free no ka plastic me ka plastic ma lalo o 121 ℃ retorting ua loaʻa i ka nui o ka noi ma waena o nā mea hana hoʻopihapiha maʻalahi.ʻO ka mea hou aku, ke ulu nei ka helu o nā hale hana e hoʻohana ana i ka PET / AL, AL / PA a me ka Plastic / AL no 121 ℃ retorting.

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

1. Hoʻomohala hou

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

Ma waho aʻe o nā mea maʻamau PET, AL, PA, RCPP, i hoʻohana ʻia no nā laminates ʻekolu a ʻehā paha, ʻike ʻia kekahi mau mea e like me nā kiʻi ʻoniʻoni aluminized transparent, retorting PVC ma ka mākeke.ʻOiai ʻaʻohe hana nui a me ka hoʻohana ʻana, pono ia mau mea i ka manawa a me ka hoʻāʻo hou aku no ka hoʻohana nui ʻana.

I kēia manawa, loaʻa i kā mākou WD8262A / B nā hihia kūleʻa i hoʻopili ʻia ma ka substrate PET / AL / PA / RCPP, hiki ke hōʻea i ka 121 ℃ retorting.No ka plastic/plastic substrate PA/RCPP, ua hoʻohana ākea ko mākou WD8166A/B i nā hihia i kūkulu ʻia.

ʻO ka wahi paʻakikī o ka laminating solvent-free, paʻi ʻia ʻo PET/Al i kēia manawa e ko mākou WD8262A/B.Ua hui pū mākou i kekahi mau mea lako lako, hoʻāʻo a hoʻoponopono iā ia no nā kaukani manawa, a hope loa i hana ʻo WD8262A/B me ka hana maikaʻi.Ma ka mokuʻo Hunan, makemake nui kā mākou mea kūʻai aku i nā laminates retorting alumini, a ʻoi aku ka maʻalahi no lākou e hana i ka hoʻokolokolo.No ka PET/AL/RCPP substrate i pai ʻia, ua uhi ʻia nā papa āpau me WD8262A/B.No ka PET / PA / AL / RCPP paʻi ʻia, hoʻohana ʻia nā ʻāpana PET / PA a me AL / RCPP 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 loaʻa i nā huahana ʻo Kangda solvent-free i kēia manawa ka holomua nui ma lalo o 128 ℃ a hoʻomau i ka paʻakikī no ka 135 ℃ a hiki i ka 145 ℃ ke kiʻekiʻe wela retorting lapaʻau.Aia nō ma lalo o ka noiʻi ʻana ke kūʻē kemika.

HOAO HANA

Nā pilikia:

ʻO ka pilikia nui o ka hana ʻana i ʻehā mau ʻāpana alumini retorting pouches ʻo ka ʻimi ʻana i ka hui kūpono o nā mea like ʻole, me nā kiʻiʻoniʻoni, adhesives, inika a me ka solvent.ʻO ka mea nui, ʻo ka hana ʻana i paʻi piha ʻia ʻo PET / AL i kēia papa waho ka mea paʻakikī loa.Ma mua mākou e alo i kēia mau hihia, i ka wā i lawe ai mākou i nā mea mai nā mea kūʻai aku i kā mākou hale hana a hoʻāʻo i nā mea āpau me nā lako, ʻaʻohe hewa i ʻike ʻia.Eia nō naʻe, i ka wā i hui pū ai mākou i nā mea āpau, ʻaʻole ʻoluʻolu ka hana o nā laminates.Aia wale nō ke hoʻomalu piha ʻia nā ʻenehana, nā lako, nā mea hana, hiki ke hana maikaʻi ʻia ka substrate.Hiki i nā hale hana ʻē aʻe ke hana i kēia substrate ʻaʻole ia he hiki i kekahi ke hoʻokō i ka kūleʻa.

2. Nā wahi mana i ka wā hana

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

2) Ka haʻahaʻa a puni

Manaʻo ʻia ka haʻahaʻa o ka lumi ma waena o 40% - 70%.ʻO ka wai i loko o ka ea e komo i ka hopena o ka adhesive, e hōʻemi ka haʻahaʻa kiʻekiʻe i ke kaumaha o ka molecular adhesive a lawe mai i kekahi mau sub-rections, e hoʻohuli ana i ka hana o ka hoʻihoʻi kūʻē.

3) Nā hoʻonohonoho ma ka laminator

Wahi a nā mīkini ʻokoʻa, pono e hoʻāʻo ʻia nā hoʻonohonoho kūpono e like me ke ʻano ʻino, kaomi, mixer e ʻike i kahi noi kūpono a hana i nā laminates palahalaha.

4) Nā koi no nā kiʻiʻoniʻoni

ʻO ka planeness maikaʻi, ka waiwai dyne kūpono, ka liʻiliʻi a me ka ʻoluʻolu a me nā mea e pono ai no ka hoʻihoʻi ʻana i ka laminating.

3. Nā hana e hiki mai ana

I kēia manawa, ʻo ka hoʻohana ʻana i ka lamination me ka solvent-free ma luna o ka pack flexible, nona ka hoʻokūkū ikaika.Ma nā wahi pilikino, aia 3 mau ala no ka hoʻomohala ʻana i ka lamination me ka solvent-free.

ʻO ka mea mua, hoʻokahi hiʻohiʻona me nā noi hou aku.Hiki i hoʻokahi huahana ke hana i ka hapa nui o nā substrate o ka mea hana hoʻopihapiha maʻalahi, hiki ke mālama i ka manawa nui, hoʻopili a hoʻonui i ka pono.

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

ʻO ka hope, palekana o ka meaʻai.I kēia manawa ua ʻoi aku ka pilikia o ka lamination me ka solvent-base no ka mea aia kekahi mau kaohi i nā huahana hana kiʻekiʻe e like me 135 ℃ retorting pouches.

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