He aha nā ʻāpana o ka plastic?

ʻO ka plastic a mākou e hoʻohana pinepine ai, ʻaʻole ia he mea maʻemaʻe, ua hana ʻia mai nā mea he nui.I waena o lākou, ʻo nā polymers molecular kiʻekiʻe nā mea nui o nā plastics.Eia kekahi, i mea e hoʻomaikaʻi ai i ka hana o nā plastics, pono e hoʻohui ʻia nā mea kōkua like ʻole, e like me nā mea hoʻopihapiha, plasticizers, lubricants, stabilizers, colorants, etc., i ka polymer.ʻO ka plastik hana maikaʻi.
ʻO ka ʻeke plastik synthetic resin: ʻO ka polymer molecular kiʻekiʻe, i kapa ʻia hoʻi ka resin synthetic, ʻo ia ka mea nui o ka plastic, a ʻo kāna ʻike i loko o ka plastic he 40% a 100%.Ma muli o ka nui o nā mea a me nā waiwai o nā resins e hoʻoholo pinepine i nā waiwai o nā plastics, manaʻo pinepine ka poʻe i ka resins e like me ka plastics.

ʻO nā mea hoʻopihapiha ʻeke plastik: kapa ʻia nā mea hoʻopihapiha hoʻopihapiha, hiki ke hoʻomaikaʻi i ka ikaika a me ka pale wela o nā plastics a hoʻemi i nā kumukūʻai.No ka laʻana, hiki i ka hoʻohui ʻana i ka pauka lāʻau i ka resin phenolic ke hōʻemi nui i ke kumukūʻai, e hana ana i ka plastic phenolic kekahi o nā plastics cheapest, a i ka manawa like, hiki iā ia ke hoʻomaikaʻi nui i ka ikaika mechanical.Hiki ke hoʻokaʻawale ʻia nā mea hoʻopihapiha i nā mea hoʻopihapiha organik a me nā mea hoʻopihapiha inorganic, ka mea mua e like me ka palaoa lāʻau, nā lole lole, ka pepa a me nā ʻano lole lole like ʻole, etc.
Pākīpika ʻeke plasticizers: Hiki i nā plasticizers ke hoʻonui i ka palaka a me ka palupalu o nā plastik, hoʻemi i ka palupalu, a maʻalahi i ka hana ʻana a me ke ʻano o nā plastic.ʻO ka plasticizer ka resin-miscible, non-toxic, odorless, high-boiling organic compounds i kūpaʻa i ka māmā a me ka wela.ʻO ka mea maʻamau i hoʻohana ʻia he phthalates.
Mea hoʻopalekana ʻeke plastik: I mea e pale aku ai i ka resin synthetic mai ka decomposed a luku ʻia e ka māmā a me ka wela i ka wā o ka hana ʻana a me ka hoʻohana ʻana, a hoʻolōʻihi i ke ola lawelawe, pono e hoʻohui ʻia kahi stabilizer i ka plastic.ʻO ka mea maʻamau ka stearate, epoxy resin a pēlā aku.

Nā waihoʻoluʻu ʻeke plastik: Hiki i nā kala kala ke hāʻawi i nā ʻano kala ʻulaʻula nani.Hoʻohana mau ʻia nā mea waihoʻoluʻu a me nā puaʻa inorganic ma ke ʻano he kala.
ʻO ka lubricant ʻeke plastik: ʻO ka hana o ka lubricant ka pale ʻana i ka plastic mai ka hoʻopili ʻana i ka pahu metala i ka wā e hoʻoheheʻe ʻia, a i ka manawa like e hoʻomaʻamaʻa a nani hoʻi ka ʻili o ka plastic.ʻO nā lubricants maʻamau ka stearic acid a me kāna mau paʻakai calcium a me ka magnesium.
Ma waho aʻe o nā mea hoʻohui i luna, hiki ke hoʻohui ʻia nā mea pale ahi, nā mea hoʻoulu, nā mea antistatic, etc.
