ʻO ke kaʻina hana o ka polyethylene resin

ʻO ka polyethylene resin he mea thermoplastic, a ua māhele pinepine ʻia kāna hana hana i ka steps:

1. Ka hoʻomākaukau ʻana i nā mea maka: ʻO ka mea maka no ka polyethylene he ethylene gas, ka mea maʻamau i lawe ʻia mai nā wahie fossil e like me ka aila, ke kinoea maoli, a i ʻole ka lanahu. Pono e mālama mua ʻia ke kinoea Ethylene, e like me ka dehydration a me ka desulfurization, ma mua o ke komo ʻana i ka reactor polymerization.
2. ʻO ka hopena polymerization: I loko o ka reactor polymerization, ke kinoea ethylene e hana i ka polymerization ma o nā ʻano polymerization kiʻekiʻe a i ʻole haʻahaʻa. Lawe ʻia ka polymerization kiʻekiʻe ma lalo o 2000-3000 atmospheres, a koi i nā catalysts, kiʻekiʻe wela, a me ke kaomi kiʻekiʻe e hāpai i ka hopena polymerization; lawe ʻia ka polymerization haʻahaʻa haʻahaʻa ma lalo o 10-50 ea, a koi i nā catalysts a me ka wela e hāpai i ka hopena polymerization.
3. Hoʻomaʻamaʻa Polymer: ʻO ka polymer i loaʻa ma hope o ka hopena polymerization pono e mālama ʻia, maʻamau me ka hoʻopili ʻana, ka ʻokiʻoki, ka hoʻoheheʻe ʻana, ka hana ʻana, etc.
4. Pelletizing: Ma hope o ka hana ʻana o ka polymer e ka extrusion, ʻokiʻoki, a me nā kaʻina hana ʻē aʻe, hana ʻia ia i nā ʻāpana polyethylene no ka lawe ʻana a me ka mālama ʻana.

He mea make ka polyethylene resin?

ʻO ka polyethylene resin ponoʻī ʻaʻole ia he mea ʻawaʻawa, ʻo kāna mau mea nui he kalapona a me ka hydrogen, ʻaʻohe ona mea ʻona. No laila, ʻaʻole hana nā huahana polyethylene i nā mea ʻawaʻawa. Eia nō naʻe, hiki ke hoʻohana ʻia kekahi mau kemika i ke kaʻina hana o nā huahana polyethylene, e like me nā catalysts, solvents, etc., hiki ke hōʻino i ke olakino kanaka. I ka manawa like, hiki ke hana ʻia nā kinoea pōʻino e like me nā mea hoʻohuihui kūlohelohe i ka wā o ka hana ʻana i nā huahana polyethylene, a pono e lawe ʻia nā hana hoʻoheheʻe kūpono. Eia kekahi, i ka wā e wela ai nā huahana polyethylene i nā mahana kiʻekiʻe, hiki ke hoʻokuʻu ʻia nā mea ʻino e like me carbon monoxide a me carbon dioxide, no laila pono e lawe ʻia nā hana palekana i ka wā e hoʻomehana ai. Ma ka laulā, ʻo ka polyethylene ponoʻī ʻaʻole ia he mea ʻawaʻawa, akā i ka hana ʻana a me ka hana ʻana i nā huahana polyethylene, pono e uku ʻia i ka palekana o ka hoʻohana ʻana a me ka mālama ʻana i nā kemika, a pono e lawe ʻia nā hana pale kūpono i ka wā e hoʻohana ai a mālama i nā huahana polyethylene.

ʻO ka hoʻomohala ʻana a me ka hoʻohana ʻana i ka ʻeke plastik polyethylene

Moʻolelo hoʻomohala: Ua ʻike mua ʻia nā ʻeke plastik polyethylene i ka makahiki 1950 a ua hoʻohana nui ʻia no ka hoʻopili ʻana i nā huahana mahiʻai a me nā waiwai ʻoihana. Me ka hoʻomohala ʻana o ka hoʻokele waiwai a me ka hoʻomaikaʻi ʻana i nā kūlana ola o nā kānaka, ua piʻi mālie ka noi no nā ʻeke plastik polyethylene, a ua puka pū kekahi mau pilikia haumia kaiapuni. No ka hoʻoponopono ʻana i kēia mau pilikia, hoʻomaka ka poʻe e ʻimi i ke ala hoʻomohala hoʻomau o nā ʻeke plastik polyethylene, e like me ka hoʻohana ʻana i nā mea hou e like me nā plastic degradable a me ka hoʻoikaika ʻana i nā hana hana hou.

Nā manaʻo noiʻi: Me ka hoʻomohala ʻana o ka hoʻokele waiwai honua a me ka hoʻonui ʻana i ka ʻike kaiapuni o ka poʻe, ʻoi aku ka laulā o ka noi no nā ʻeke plastik polyethylene. Ma waho aʻe o ke kahua paʻi kuʻuna, hiki ke hoʻohana ʻia nā ʻeke plastik polyethylene i ka mahiʻai, ka lāʻau lapaʻau, ka mālama ʻana i ke kaiapuni a me nā ʻano ʻē aʻe, e like me ka hoʻohana ʻia no ka hoʻokaʻawale ʻana i ka ʻōpala, ka hoʻokuʻu ʻana i nā ʻōpala, nā kiʻiʻoniʻoni mahiʻai, a me nā mea ʻē aʻe. o ka ʻenehana, e hoʻomaikaʻi hou ʻia ka hana o nā ʻeke plastik polyethylene, e like me ka hoʻomaikaʻi ʻana i ka ikaika, ka hoʻonui ʻana i ka hanu, ka wikiwiki o ka hoʻohaʻahaʻa ʻana, a me nā mea ʻē aʻe.

Nā waiwai kino a me nā kemika o ka resin polyethylene

ʻO ka polyethylene resin kahi polymer thermoplastic me nā ʻano kino a me nā ʻano kemika:

Ka hoʻohana ʻana i ka resin polyethylene i loko o ka pauka

Hoʻohana nui ʻia ka polyethylene resin i ka pauka. ʻO ka uhi ʻana o ka pauka he mea hoʻoheheʻe ʻole, non-volatile organic coating me ka mālama ʻana i ke kaiapuni, kiʻekiʻe kiʻekiʻe, a me nā pono mālama ola. ʻO ka polyethylene resin kahi mea waiwai nui no ka uhi ʻana i ka pauka, i hoʻohana nui ʻia ma nā wahi aʻe:

• Hiki ke hoʻohana ʻia ka polyethylene resin ma ke ʻano he kiʻi ʻoniʻoni nui o ka pauka, me ka hoʻopili maikaʻi ʻana, ke kūpaʻa ʻana, a me ka pale ʻana i ka wā, hiki ke pale i ka ʻili o ka mea i uhi ʻia mai ka corrosion a me ka oxidation.
• Hiki ke hoʻohana ʻia ka polyethylene resin ma ke ʻano he plasticizer no ka uhi ʻana i ka pauka, hiki ke hoʻomaikaʻi i ka maʻalahi a me ka pale ʻana i ka hopena o ka uhi, e ʻoi aku ka lōʻihi o ka uhi.
• Hiki ke hoʻohana ʻia ka polyethylene resin ma ke ʻano he mea hoʻonaninani no ka uhi ʻana i ka pauka, hiki ke hoʻomaikaʻi i ka ʻōlinolino a me ka maʻalahi o ka ʻili o ka uhi, e ʻoi aku ka nani o ka uhi.
• Hiki ke hoʻohana ʻia ka polyethylene resin ma ke ʻano he antioxidant no ka pauka pauka, hiki ke hoʻolōʻihi i ke ola lawelawe o ka uhi a hoʻomaikaʻi i kona lōʻihi.

I ka hōʻuluʻulu ʻana, hiki i ka hoʻohana ʻana i ka polyethylene resin i ka pauka pauka ke hoʻomaikaʻi i ka hana a me ka maikaʻi o ka uhi ʻana, ʻoiai e hoʻokō ana i nā koi o ka mālama ʻana i ke kaiapuni a me ka loaʻa ʻana o ka mākeke ākea.
