ʻOkoʻa ma waena o LLDPE a me LDPE
Ka ʻokoʻa ma waena o ka linear low density polyethylene (LLDPE) a me ka low density polyethylene (LDPE)
1. Wehewehe
ʻO ka linear low density polyethylene (LLDPE) a me ka haʻahaʻa haʻahaʻa polyethylene (LDPE). Eia naʻe, ʻokoʻa lākou i ke ʻano o ke ʻano; Hoʻomākaukau ʻia ʻo LLDPE me ka hoʻohana ʻana i kahi ʻenehana catalyst hoʻokahi, e hopena i kahi ʻano laina a me ka nui kiʻekiʻe, ʻoiai ua loaʻa iā LDPE kahi ʻano kaulahao maʻamau me ka haʻahaʻa haʻahaʻa.
2. Na waiwai kino
Hōʻike ʻo LLDPE i nā ʻokoʻa like ʻole ma ke ʻano o ka mānoanoa a me ka helu heheʻe i hoʻohālikelike ʻia me LDPE. ʻO ka laulā maʻamau maʻamau no LLDPE ma waena o 0.916-0.940g/cm3, me kahi pae hoʻoheheʻe o 122-128 ℃. Eia kekahi, hōʻike ʻo LLDPE i ka ikaika a me nā ʻano pale wela.
Ma ka ʻaoʻao ʻē aʻe, loaʻa ka LDPE maʻamau mai 0.910 a i 0.940g/cm3 a me kahi pae hoʻoheheʻe o 105-115 ℃ ʻoiai e hāʻawi ana i ka maʻalahi a me ka paʻakikī.
3. Nā ʻano hana
I ka wā o ka hana ʻana, hiki ke hana ʻia ʻo LDPE ma o ka hoʻoheheʻe ʻana a i ʻole nā ʻenehana extrusion e hana i nā ipu like ʻole a me nā mea hoʻopili e like me nā kiʻiʻoniʻoni a me nā ʻeke. ʻO ka hoʻohālikelike ʻana, ma muli o kona ʻoi aku ka nui o ka lawe ʻana i ka ukana a me ka ikaika mechanical, ʻoi aku ka maikaʻi o ka LLDPE no ka extruding tubes a me nā kiʻiʻoniʻoni.
4.Application kahua
Ma muli o ko lākou mau waiwai kino like ʻole a me nā ʻano hana hana, ʻike ʻia ʻo LLDPE a me LDPE i nā noi ma nā kahua like ʻole. Kūpono ʻia ʻo LLDPE no ka hana ʻana i nā kiʻiʻoniʻoni kiʻekiʻe / paipu i hoʻohana ʻia i ka hana ʻana i nā mea hoʻopihapiha e like me nā uhi mahiʻai, nā kiʻiʻoniʻoni wai a me nā uea / uwea. ʻO ka mea ʻē aʻe, ʻike ʻo LDPE i ka mea kūpono i ka hana ʻana i nā huahana palupalu e like me nā plugs toys wai paipu ipu me nā mea hoʻopili.
Ma ke ʻano holoʻokoʻa, ʻoiai ʻo LLDP a me LPDE ʻelua i loko o ka ʻāpana o ka polyethylene plastics, hōʻike lākou i nā ʻokoʻa koʻikoʻi ʻaʻole wale e pili ana i nā waiwai kino, nā ʻano hana akā i nā kahua noi.
