LDPE 202TN00 papa kiʻiʻoniʻoni,
polyethylene kiʻekiʻe, ldpe no ka hana kiʻiʻoniʻoni, Polyethylene Haʻahaʻa Haʻahaʻa,

ʻO ka polyethylene haʻahaʻa haʻahaʻa (LDPE) he resin synthetic e hoʻohana ana i ke kaʻina hana kaomi kiʻekiʻe ma o ka polymerization radical manuahi o ka ethylene a no laila ua kapa ʻia ʻo ia he "polyethylene high-pressure".ʻO ka polyethylene puʻupuʻu haʻahaʻa ʻole, ʻono ʻole, nā ʻāpana keʻokeʻo ʻona ʻole a i ʻole ka pauka.He 131 ℃ ka helu hehee.Māmā 0.910-0.925 g/cm³.He 120-125 ℃ ke kiko palupalu.Embrittlement wela -70 ℃.ʻO ka mahana hana kiʻekiʻe 100 ℃.Me ke kūpaʻa wela maikaʻi, ke kūpaʻa anu, ke kūpaʻa ʻaʻahu a me nā waiwai dielectric, kūpaʻa kemika.ʻAneʻane hiki ʻole ke hoʻoheheʻe ʻia i loko o kekahi mea hoʻoheheʻe organik ma ka lumi wela.Hiki ke pale aku i ka ʻino o nā ʻakika like ʻole a me ka alkali a me nā ʻano paʻakai like ʻole.Hoʻohana nui ʻia ka polyethylene haʻahaʻa haʻahaʻa i nā lāʻau lapaʻau a me nā ʻoihana kemika e hana i nā huahana hollow, e like me nā barela, nā hue a me nā pahu mālama.Hoʻohana ka ʻoihana meaʻai iā ia e hana i nā pahu pahu.Hoʻohana ʻia ka ʻoihana mīkini e hana i nā uhi, nā lima, nā huila lima a me nā ʻāpana mīkini maʻamau, a hoʻohana ʻia ka ʻoihana pepa e hana i ka pepa synthetic.

ʻO LDPE (2102TN000) kahi mea kiʻi extrusion maikaʻi loa, kūpono no ka hana ʻana i ke kiʻi ʻoniʻoni kaumaha, hoʻokahe kiʻiʻoniʻoni, wela shrinkable packaging film a pēlā aku. , nā keke, ka pauka waiu, ke kī, ka floss iʻa a me nā ʻeke meaʻai ʻē aʻe.Hoʻopili ʻia no nā papa, pauka a me nā lāʻau lapaʻau ʻē aʻe, hoʻopili no nā pālule, nā lole, nā huahana pulupulu i ulana ʻia a me nā huahana fiber kemika a me nā huahana fiber ʻē aʻe.ʻO ka pauka holoi, ka mea hoʻomaʻemaʻe, nā mea hoʻonaninani a me nā mea ʻē aʻe o kēlā me kēia lā.Ma muli o ka maikaʻi ʻole o nā ʻano hana ʻino o ke kiʻi ʻoniʻoni PE hoʻokahi, hoʻohana mau ʻia ʻo ia e like me ka papa o loko o nā ʻeke hoʻopili composite, ʻo ia hoʻi, ka substrate hoʻopaʻa wela o nā kiʻi ʻoniʻoni multi-layer.

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.
