Haʻahaʻa haʻahaʻa Polyethylene resin
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
Hoʻopili ʻia ka resin i loko o nā ʻeke ulana polypropylene i uhi ʻia i loko.ʻO ka paona ʻupena he 25Kg / ʻeke.Pono e mālama ʻia ka resin i loko o kahi waihona maloʻo a maloʻo a mamao i ke ahi a me ka lā pololei.ʻAʻole pono e hoʻahu ʻia ma ka lewa ākea.I ka wā o ka lawe ʻana, ʻaʻole pono e ʻike ʻia ka huahana i ka lā ikaika a i ʻole ka ua a ʻaʻole pono e lawe pū ʻia me ke one, lepo, metala ʻōpala, lanahu a i ʻole aniani.ʻAʻole loa e pāpā ʻia ka lawe ʻana me nā mea ʻawaʻawa, corrosive a me ke ahi.
