ʻike kiʻiʻoniʻoni hiki ke hoʻemi ʻia ka PE

Hoʻokaʻawale ʻana i ka kiʻiʻoniʻoni wela LDPE

Hoʻokaʻawale ʻia nā kiʻi ʻoniʻoni wela LDPE i ʻelua mau ʻāpana: pili kea a me ka pili ʻole.ʻO ka maʻamau, hoʻohana nā mea hana i nā mea maka me MFR o 0.3-1.5g/10min i ka wā e hana ana i nā kiʻi ʻoniʻoni wela LDPE pili ʻole.ʻO ka haʻahaʻa o ka melt index, ʻoi aku ka lōkahi o ka hana shrinkage.A ʻoi aku ka nui o ka ikaika tensile, ʻoi aku ka maikaʻi no ka hoʻopili ʻana.Hoʻohana kekahi mau mea hana i ka lapaʻau radiation i ka hana ʻana e hoʻomaikaʻi i nā waiwai like ʻole o nā kiʻi ʻoniʻoni wela.
Hiki i ka PE heat shrinkable film ke hoʻokō i nā koi hoʻopihapiha o ka hapa nui o nā mea kūʻai aku, a ʻo ia ka kiʻi ʻoniʻoni wela wela.ʻO ka MI i hoʻohana ʻia i nā ʻāpana LDPE he 0.3-1.5g / min.Hoʻopiʻi ʻia ke kiʻi ʻoniʻoni a i ʻole nā ​​​​kiʻi ʻoniʻoni me nā koi ikaika kiʻekiʻe, e hoʻohana i nā ʻāpana LDPE me ka palena haʻahaʻa o MI, ʻo LDPE ka hoʻoheheʻe ʻana o ka mahana he 130-180 ℃, ma mua o ke anuanu me ke ea anuanu ma lalo o 25 ℃, a laila e hoʻoulu kokoke i ka laina hau, I ka manawa lōʻihi a me ka transverse stretching, hiki i ka nui o ka hoʻolōʻihi ʻana ke hiki i ka 15-35, a laila hoʻopau ʻia ke kiʻiʻoniʻoni ma 10-25 ° C e makani aiʻole e hōʻemi i ke kiʻiʻoniʻoni.ʻO 30%-50% ka nui o ka emi ʻana.
ʻO nā hiʻohiʻona:
1. ʻO ke kiʻi ʻoniʻoni LDPE shrink uncrosslinked he palupalu, maikaʻi ka hopena o ka hopena, a he ikaika waimaka;
2. ʻO ke kūpaʻa haʻahaʻa haʻahaʻa maikaʻi;
3. Maʻalahi e hana a hana, maʻalahi e wela i ka ʻeke sila;
4. ʻAʻole hiki ke emi i ka wā mālama.E ho'ēmi i ka uhiʻana no ke aniani, ka seramika, ka meaʻai, nā mea kūkulu hale, nā kinikona, nā pallets, a me nā mea'ē aʻe.

Nā waiwai o LDPE hōʻemi kiʻiʻoniʻoni:
1. ʻO 0.02-0.05mm ka mānoanoa kiʻi lahilahi, 0.05-0.10mm ke ʻano waena, a ʻo 0.10-0.15mm ka mānoanoa;
2. ʻO ka ikaika tensile he 28-38MPa no ke ʻano lahilahi, 20-30MPa no ke ʻano waena, a me 20-28MPa no ke ʻano mānoanoa;
3. He 55% -65% ka emi ana o ke ano lahilahi, he 45% -60% ka manoanoa, he 30% -50% ka manoanoa;ʻO ka ʻauʻau ʻaila shrinkage he 110-120 ℃, ʻo ka ea wela he 170-180 ℃;
4. ʻO 5-10s ka manawa hoʻohaʻahaʻa no ke ʻano lahilahi a me 20-30s no ke ʻano mānoanoa.
ʻO ka mānoanoa liʻiliʻi o ke kiʻi liʻiliʻi no ka hoʻopili ʻana ma lalo o 400kg ʻo 120μm, 800kg pono 150μm mānoanoa, a me 1200kg waiwai pono LDPE emi kiʻi me 200μm mānoanoa.
