Nā ʻano ʻeke ʻeke waiu a me nā koi hana kiʻiʻoniʻoni

Nā ʻano ʻeke ʻeke waiu a me nā koi hana kiʻiʻoniʻoni

No ka mea he mea inu hou ka waiū, ʻo nā koi no ka maʻemaʻe, ka bacteria, ka mahana, a me nā mea ʻē aʻe.No laila, aia kekahi mau koi kūikawā no ka paʻi ʻana i nā ʻeke paʻi, kahi e hoʻokaʻawale ai ka paʻi ʻana i ke kiʻi ʻoniʻoni waiu mai nā ʻano ʻenehana paʻi ʻē aʻe.No ke koho ʻana i ke kiʻi ʻoniʻoni waiu, pono ia e hoʻokō i nā koi o ka paʻi ʻana, paʻi ʻana, ka hana ʻana, mālama a me ka lawe ʻana a me ka maʻemaʻe.I kēia manawa, ʻo ka mea kiʻiʻoniʻoni maʻamau ka polyethylene (PE) co-extruded film, ʻo ia ka hoʻoheheʻe ʻana o ka polyethylene resin a me ka hoʻoheheʻe ʻana.

Nā ʻeke ʻeke ʻeke maʻemaʻe ʻo Top Spout ʻeke Waiwai waiʻona

Nā ʻano kiʻiʻoniʻoni no ka ʻeke waiu:

E like me kona ʻano papa, hiki ke hoʻokaʻawale ʻia i ʻekolu ʻano.
1. Kiʻiʻoniʻoni hoʻopili maʻalahi
ʻO ka maʻamau he kiʻi ʻoniʻoni hoʻokahi, i hana ʻia ma ka hoʻohui ʻana i kekahi māhele o ka masterbatch keʻokeʻo i nā mea polyethylene like ʻole a hana ʻia e nā lako kiʻiʻoniʻoni puhi.ʻO kēia kiʻi paʻi kiʻi he hale pale ʻole a hoʻopiha piha ʻia e ka pasteurization (85 ° C / 30min), me kahi ola pōkole pōkole (ma kahi o 3 mau lā).
2. ʻEleʻele a me ke keʻokeʻo co-extrusion pahu kiʻiʻoniʻoni me ʻekolu papa hana
He kiʻi kiʻiʻoniʻoni kiʻekiʻe i hana ʻia me LDPE, LLDPE, EVOH, MLLDPE a me nā resins ʻē aʻe, i hoʻopili ʻia a puhi ʻia me nā masterbatches ʻeleʻele a keʻokeʻo.ʻO ka masterbatch ʻeleʻele i hoʻohui ʻia i ka pae wela-seal i loko ke kuleana o ka pale ʻana i ke kukui.Hoʻohana ʻia kēia kiʻi paʻi kiʻi ʻoniʻoni ultra-kiʻekiʻe i ka sterilization koke a me ka hydrogen peroxide sterilization, a hiki i ke ola o ke ola ma kahi lumi lumi ma kahi o 30 mau lā.
3. ʻEleʻele a me ke keʻokeʻo co-extrusion pahu kiʻiʻoniʻoni me ka pae ʻelima
Hoʻohui ʻia kahi papa pale waena (i haku ʻia me nā resins pale kiʻekiʻe e like me EVA a me EVAL) ke puhi ʻia ke kiʻiʻoniʻoni.No laila, ʻo kēia kiʻi paʻi kiʻi he kiʻi kiʻi ʻoniʻoni aseptic kiʻekiʻe me ka lōʻihi o ke ola ʻana a hiki ke mālama ʻia i ka lumi lumi no kahi o 90 mau lā.ʻO nā kiʻi ʻoniʻoni ʻeleʻele a me ke keʻokeʻo i hoʻopili ʻia he ʻekolu-layer me nā mea hoʻopaʻa wela maikaʻi loa, ke kūpaʻa māmā a me ka oxygen, a loaʻa iā ia nā pōmaikaʻi o ke kumu kūʻai haʻahaʻa, ʻoi aku ka maikaʻi o ka lawe ʻana, kahi wahi mālama liʻiliʻi, a me ka hana ikaika.

ʻOla kiʻiʻoniʻoni lole maʻamau

Nā koi hana o ka polyethylene film no nā huahana waiu:
I mea e hoʻokō ai i nā koi o ka hoʻopiha ʻana i ka waiū a me ka paʻi ʻana, ʻo nā ʻano aʻe e koi nui ʻia no ka polyethylene film.
1. Ka maʻalahi
ʻO nāʻaoʻao o loko a me waho o ka kiʻiʻoniʻoni pono e loaʻa ka maʻalahi maikaʻi e hiki ai ke hoʻopiha ponoʻia ma ka mīkini hoʻopihapiha hoʻopihapiha kiʻekiʻe.No laila, pono e haʻahaʻa loa ka coefficient dynamic friction o ka ʻili kiʻi, maʻamau e koi ana i ka 0.2 a i ka 0.4 ʻO ka maʻalahi o ke kiʻiʻoniʻoni Ma hope o ka hoʻokumu ʻia ʻana o ke kiʻiʻoniʻoni, neʻe ka mea paheʻe mai ke kiʻiʻoniʻoni a i ka ʻili a hōʻiliʻili i kahi ʻāpana lahilahi. , hiki ke hoʻemi nui i ka friction coefficient o ke kiʻiʻoniʻoni a hoʻolilo i ke kiʻiʻoniʻoni maikaʻi.Ka hopena.
2. Ka ikaika tensile
No ka mea e pili ana ke kiʻi ʻoniʻoni i ka ʻenekini mechanical mai ka mīkini hoʻopiha piha i ka wā o ka hoʻopiha piha ʻana, pono e loaʻa i ka kiʻiʻoniʻoni ka ikaika tensile lawa e pale aku ai i ka huki ʻia ʻana ma lalo o ke ʻano o ka mīkini hoʻopiha piha.I ke kaʻina hana puhi kiʻiʻoniʻoni, ʻo ka hoʻohana ʻana i nā ʻāpana LDPE a i ʻole HDPE me kahi helu hoʻoheheʻe haʻahaʻa he mea maikaʻi loa ia e hoʻomaikaʻi i ka ikaika tensile o nā kiʻiʻoniʻoni polyethylene.
3. Ka hoʻomāmā ʻana o ka ʻili
I mea e laha ai ka inika paʻi, pulu a pili pono i ka ʻili o ka polyethylene plastic film, pono e hiki i ka ʻili o ke kiʻiʻoniʻoni ke hōʻea i kahi kūlana, a pono e hilinaʻi i ka mālama corona e hoʻokō ai i kahi kūlana. ʻoi aku ka nui o ka hoʻoluhi ʻana, inā ʻaʻole ia e hoʻopilikia i ka ʻīnika ma ke kiʻiʻoniʻoni.ʻO ka hoʻopili ʻana a me ka paʻa o ka ʻili, no laila e pili ana i ka maikaʻi o ka mea i paʻi ʻia.ʻO ka mea maʻamau e koi ʻia ʻo ka ʻili o ka ʻili o ka polyethylene film ma luna o 38dyne, a ʻoi aku ka maikaʻi inā hiki ke piʻi ma luna o 40dyne.No ka mea ʻo ka polyethylene kahi mea polymer non-polar maʻamau, ʻaʻole ia i loko o nā pūʻulu polar i loko o kona ʻano mole, a he kiʻekiʻe ka crystallinity, haʻahaʻa haʻahaʻa ka ikehu manuahi, ikaika inertness, a paʻa kemika waiwai.No laila, ʻoi aku ka kiʻekiʻe o ka paʻi ʻana i nā mea kiʻiʻoniʻoni.ʻAʻole kūpono ka hoʻopili ʻana i ka inika.
4. Hoʻopaʻa wela
ʻO ka mea hopohopo nui e pili ana i ka hoʻopili kiʻiʻoniʻoni maʻalahi ka pilikia o ka haki ʻana o ka ʻeke ma muli o ka leakage a me ka sila hoʻopunipuni.No laila, pono e loaʻa i ka kiʻiʻoniʻoni nā mea hana ʻeke wela maikaʻi, hana hoʻopaʻa hoʻopaʻa maikaʻi, a me kahi ākea ākea wela, i hiki ke hoʻohana ʻia i ka hoʻopili.Ke hoʻololi ka wikiwiki, ʻaʻole i hoʻopilikia nui ʻia ka hopena sealing wela, a hoʻohana pinepine ʻia ʻo MLDPE ma ke ʻano he wela wela e hōʻoia pono i ka paʻa o nā kūlana hoʻopaʻa wela a me ka hoʻopaʻa ʻana i ka wela.ʻO ia hoʻi, pono e hōʻoia i ka hoʻopaʻa ʻana i ka wela a hiki ke ʻoki mālie i ʻole e pili ka resin hoʻoheheʻe i ka pahi.

ʻO ka hoʻohui ʻana i kekahi hapa o LLDPE i ke kaʻina puhi kiʻiʻoniʻoni hiki ke hoʻomaikaʻi maikaʻi i ka hana haʻahaʻa haʻahaʻa wela wela a me ka hoʻokomo ʻana i ka hana hoʻopaʻa ʻana i ka wela o ka kiʻiʻoniʻoni, akā ʻaʻole nui ka nui o ka LLDPE i hoʻohui ʻia, inā ʻaʻole e lilo ka viscosity o ka polyethylene film. kiʻekiʻe loa, a me ke kaʻina hana hoʻopaʻa wela He mea maʻalahi i ka paʻa ʻole o ka pahi.No ka hoʻolālā hoʻolālā ʻana o ke kiʻiʻoniʻoni, hiki ke koho ʻia ke kiʻi ʻoniʻoni o ka hale pili e like me nā ʻokoʻa like ʻole o ka pūʻolo a me kona ola paʻa.
