ʻO ka polyethylene haʻahaʻa haʻahaʻa no ke kiʻiʻoniʻoni puhi
ʻO ka polyethylene haʻahaʻa haʻahaʻa no ke kiʻiʻoniʻoni puhi,
Papa kiʻiʻoniʻoni LDPE, ldpe no ka hana kiʻiʻoniʻoni,
ʻO ka polyethylene haʻahaʻa haʻahaʻa (LDPE) he resin synthetic me ka hoʻohana ʻana i ke kaʻina hana kiʻekiʻe ma o ka polymerization radical manuahi o ka ethylene a no laila ua kapa ʻia ʻo ia ʻo "high-pressure polyethylene".No ka mea he nui nā lālā lōʻihi a pōkole o kāna kaulahao molekala, ʻoi aku ka liʻiliʻi o ka LDPE ma mua o ka polyethylene kiʻekiʻe (HDPE) a ʻoi aku ka haʻahaʻa.Hōʻike ia i ka māmā, hiki ke maʻalahi, maikaʻi ke kūpaʻa hau a me ka hopena.Paʻa kemika ʻo LDPE.He kūpaʻa maikaʻi kona i nā waikawa (koe naʻe nā waikawa oxidizing ikaika), alkali, paʻakai, nā waiwai insulation uila maikaʻi loa.He haʻahaʻa kona komo ʻana i ka mahu.Loaʻa i ka LDPE ka wai kiʻekiʻe a me ka hana maikaʻi.He kūpono ia no ka hoʻohana ʻana i nā ʻano hana hana thermoplastic a pau, e like me ka hoʻoheheʻe ʻana, ka hoʻoheheʻe extrusion, ka hoʻoheheʻe ʻana, ka rotomolding, ka uhi ʻana, ka puaʻa, ka thermoforming, ka welding hot-jet a me ka welding thermal.
Palapala noi
Hoʻohana nui ʻia ka LDPE no ka hana ʻana i nā kiʻiʻoniʻoni.Hoʻohana nui ʻia ia i ka hana ʻana i nā kiʻiʻoniʻoni mahiʻai (mulching film a me shed film), kiʻi ʻoniʻoni (no ka hoʻohana ʻana i nā lole lole, nā mea kanu a me nā meaʻai maloʻo), kiʻi ʻoniʻoni no ka hoʻopili wai (no ka hoʻohana ʻana i ka waiū paʻa, soy sauce, wai, ʻeke pīni a me ka waiu soy), ʻeke ʻeke kaumaha kaumaha, kiʻiʻoniʻoni hoʻohaʻahaʻa, kiʻi elastic, kiʻi ʻoniʻoni, kiʻi hoʻohana hale, kiʻiʻoniʻoni hoʻopihapiha hoʻopihapiha a me nā ʻeke meaʻai.
Hoʻohana nui ʻia ʻo LDPE i ka hana ʻana i ka uea a me ke kaula insulation sheath.ʻO LDPE i hoʻopaʻa ʻia ʻo Cross-linked ka mea nui i hoʻohana ʻia i ka papa insulation o nā kaula uila kiʻekiʻe.
Hoʻohana pū ʻia ʻo LDPE i ka hana ʻana i nā huahana i hoʻoheheʻe ʻia (e like me nā pua artificial, nā mea lapaʻau, nā lāʻau lapaʻau a me nā mea hoʻopili meaʻai) a me nā paipu extrusion-molded, nā pā, nā uea a me nā uhi kelepona a me nā huahana plastic profiled.
Hoʻohana ʻia ʻo LDPE no ka hana ʻana i nā huahana hollow blow-molded e like me nā ipu no ka mālama ʻana i ka meaʻai, ka lāʻau lapaʻau, nā mea hoʻonaninani a me nā huahana kemika, a me nā pahu.
Pūʻolo, Waihona a me ka lawe ʻana
ʻO ke koho o ka polyethylene blow-molded film material
1. Pono e puhi ʻia nā mea maka i koho ʻia i nā ʻāpana resin polyethylene kiʻi kiʻiʻoniʻoni, i loaʻa ka nui kūpono o ka mea hoʻomaʻemaʻe,
E hōʻoia i ka weheʻana o ke kiʻi.
2 resin particle melt index (MI) ʻaʻole hiki ke nui loa, melt index (MI) nui loa, a laila heheʻe resin
He liʻiliʻi loa ka viscosity, haiki ka pae hana, paʻakikī ka hoʻoponopono ʻana i nā kūlana hana, ʻilihune ka waiwai o ka resin, ʻaʻole maʻalahi.
Ka hana ʻana i kiʻiʻoniʻoni;Eia hou, he nui loa ka helu helu hehee (MI), he haiki loa ka puunaue kaumaha molekala polimer pili, ki'i lahilahi.
He ilihune i ka ikaika.No laila, pono e koho ʻia kahi helu hoʻoheheʻe liʻiliʻi (MI) a me ka puʻunaue kaumaha molekala pili ākea
ʻAʻole hiki ke hoʻokō wale i nā koi hana o ke kiʻiʻoniʻoni, akā e hōʻoia pū i nā ʻano hana o ka resin.
Hoʻohana maʻamau ʻo Blow molded polyethylene film i ka melt index (MI) ma ka laulā o 2 ~ 6g/10min polyethylene
ʻO nā mea maka.
