Multilayer co-extrusion puhi puhi

He aha ka multi-layer co-extrusion blow molding?

He aha ka multi-layer co-extrusion blow molding?ʻO ka multi-layer co-extrusion a me ka blow molding ka ʻenehana o ka hana ʻana i nā ipu kīwaha ma o ka puhi ʻana me ka hoʻohana ʻana i ʻoi aku ma mua o ʻelua extruders e hoʻoheheʻe a hoʻopaʻa i nā plastics like a ʻokoʻa paha i nā extruders like ʻole a laila hoʻohui, extrude a hana i nā embryos composite concentric multi-layer. ma ke poo.

ʻO ka loina kaʻina hana maʻamau e like me ka ʻenehana puhi puhi no nā huahana papa hoʻokahi.Akā ʻo nā mea hana hoʻoheheʻe e hoʻohana i ka plurality o extruder pākahi plasticizing ʻano like ʻole o ka plastic.

ʻO ka ʻenehana koʻikoʻi o ka multilayer co-extrusion blow molding ʻo ia ka mālama ʻana i ka fusion a me ka maikaʻi o ka hoʻopaʻa ʻana o kēlā me kēia papa o nā plastics.Hoʻokumu ʻia ka ʻenehana multi-layer co-extrusion blow molding e hoʻokō i nā koi kūikawā o kekahi mau ʻoihana e like me ka lāʻau lapaʻau, ka meaʻai a me ka ʻoihana no nā pahu pahu, e like me ka paʻa o ka ea, ka pale ʻana i ka corrosion a pēlā aku.E kōkua nā ʻāpana aʻe iā ʻoe e hoʻomaopopo hohonu.

ʻO nā hiʻohiʻona hoʻoheheʻe puʻupuʻu hui nui

Hana ʻia nā huahana hollow multi-layer co-extrusion blow molding i nā ʻano mea like ʻole e ke poʻo make multi-layer, i mea e hoʻokō ai i ka hana pale o ka ipu i carbon dioxide, oxygen a i ʻole gasoline.

Ke hoʻohana nei i ka co-extrusion blow molding, nā ʻano polymers i hui pū ʻia, e hana ana i kahi pahu multi-layer, i nā pono piha o nā ʻano polymers, hiki ke hoʻokō i kēia mau pahuhopu:

E hoʻomaikaʻi i ka impermeability o ka ipu e hoʻomaikaʻi ai i ka ikaika, stiffness, dimensional stability, transparency, softness, heat resistance o ka ipu, hoʻololi i ka hana ʻili o ka ipu e hoʻokō i ka manaʻo o ka ikaika a i ʻole ka hana, hoʻemi i ke kumukūʻai.

Multilayer co-extrusion blow molding mea koho

ʻO ka hoʻomohala ʻana o ka ʻenehana multi-layer co-extrusion blow molding a me ka mīkini e hiki ai ke koho i ke ʻano (layer) hui pū ʻana a hana i nā huahana puhi puhi me nā waiwai kūpono.E like me ka nui o ka huahana a me nā koi hana, hiki ke hana i 3 ~ 6 papa o ka hale.ʻO ka maʻamau, hoʻohana ʻia ke poʻo mīkini co-extrusion hiki ke hoʻohui ʻia a me ka mana logic program a i ʻole ka nānā ʻana i ka kamepiula e puʻunaue like i nā plastics multi-layer e like me ka nui o nā mea i koho ʻia, a hoʻokuʻu pū iā lākou i loko o nā bilets, i hana ʻia e ka puhi ʻana i luna. nā hale kūʻai kelepona.

Ke kohoʻana i nā mea maka, pono e hanaʻia nā papa likeʻole o nā mea likeʻole.E hoʻohana i nā mea hou a me nā mea kiʻekiʻe no ka papa o loko a me waho.E hoʻomaopopo i ka koho ʻana o nā mea pono e hoʻokumu ʻia i ka huahana hope āu e hana ai, e like me kāna mau waiwai huahana e koho i ka mea kūpono.

ʻOiai he mea hana mākou i nā mīkini hoʻoheheʻe puhi no nā pahu wai, pono mākou i kahi mīkini hoʻāʻo.Hoʻohana pinepine mākou i kā mākou mīkini e hana i nā pahu wai ke hoʻāʻo mākou iā lākou.No nā pahu wai, ʻo HDPE kahi koho maikaʻi.Hoʻohana pū mākou i ka HDPE ma ke ʻano he kumu waiwai o ka pahu wai i ka hana.Hoʻohana ka hapa nui o kā mākou mea kūʻai aku i ka HDPE ma ke ʻano he kumu no ka hana pahu wai.Hiki i kona mau waiwai ke hana i ka pahu i ʻoi aku ka lōʻihi a me ka paʻa.
