Ka ʻike kumu e pili ana i ʻekolu ʻano o ka mea PE (II)

3. LLDPE

ʻAʻole ʻawaʻawa ʻo LLDPE, ʻono a ʻala ʻole, a ʻo kona mānoanoa ma waena o 0.915 a me 0.935g/cm3.He copolymer ia o ka ethylene a me kahi mea liʻiliʻi o ka α-olefin kiʻekiʻe ma lalo o ka hana a ka catalyst, i polymerized e ke kiʻekiʻe kiʻekiʻe a i ʻole ka haʻahaʻa haʻahaʻa.Hōʻike ʻia ke ʻano molekala o LLDPE maʻamau e kona iwi kuamoʻo laina me nā lālā liʻiliʻi a ʻaʻole lōʻihi, akā aia kekahi mau lālā pōkole.ʻO ka nele o nā lālā kaulahao lōʻihi e ʻoi aku ka crystalline o ka polymer.

Ke hoʻohālikelikeʻia me LDPE, loaʻa iā LLDPE nā mea maikaʻi o ka ikaika kiʻekiʻe, ka paʻakikī maikaʻi, ka paʻakikī ikaika, ka pale wela a me ke anuanu.

Hōʻuluʻulu

I ka hōʻuluʻulu ʻana, pāʻani nā mea ʻekolu i luna i kā lākou mau hana koʻikoʻi i nā ʻano hana anti-seepage.ʻO HDPE, LDPE a me LLDPE nā mea a pau i hoʻohana nui ʻia i ka mahiʻai, ka iʻa, nā loko kūlohelohe, nā loko, a me nā kahawai, a ua hoʻohana nui ʻia lākou i ka ʻoihana. paipai ʻia a hoʻolaha ʻia e ke Keʻena lawaiʻa o ke Kuhina Mahiai o Kina, ka Shanghai Academy of Fishery Science, a me ka Institute of Fishery Machinery and Instruments.

I loko o ke kaiapuni waena o ka waikawa ikaika, kumu ikaika, oxidant ikaika a me ka solvent organik, hiki ke hoʻohana maikaʻi ʻia nā waiwai waiwai o HDPE a me LLDPE, ʻoi aku ka nui o nā waiwai o HDPE i ke kūʻē ʻana i ka waika ikaika, alkali, oxidation ikaika a me ka solvent organik.ʻOi aku ka kiʻekiʻe o ka hiʻohiʻona ma mua o nā mea ʻelua ʻē aʻe, no laila ua hoʻohana piha ʻia ʻo HDPE anti-seepage a me anti-corrosion coil i nā ʻoihana kemika a me ka mālama ʻana i ke kaiapuni.

Loaʻa i ka LDPE ka waikawa maikaʻi, ka alkali, nā ʻano hoʻonā paʻakai, a me ka extensibility maikaʻi, ka insulation uila, ke kūpaʻa kemika, ka hana ʻana a me ke kūpaʻa haʻahaʻa haʻahaʻa, no laila hoʻohana ʻia i ka mahiʻai, aquaculture, packaging, ʻoi loa. a me na mea uwea.

ʻO kanā mīkini extruding plastichana ʻia e KHMC e hoʻohana nui i ka HDPE no ka hana ʻana i ke kaula monofilament.ʻO ke kaula plastik i hanaʻia e kā mākou mīkini me ka ikaika kiʻekiʻe a me keʻano maikaʻi loa.
