No ke aha i ʻokoʻa ai ke kumukūʻai o nā kukui PS a me PC ma ka mākeke? I kēia lā, e hoʻolauna wau i nā ʻano o nā mea ʻelua.
1. Polystyrene (PS)
• Waiwai: Polymer amorphous, emi ka emi ʻana ma hope o ke kālai ʻia ʻana ma lalo o 0.6; ʻo ka haʻahaʻa haʻahaʻa e hana i ka hopena he 20% a 30% ʻoi aku ka nui ma mua o ka mea maʻamau
• Nā Pōmaikaʻi: haʻahaʻa ke kumukūʻai, moakaka, hiki ke hoʻoluʻu ʻia, nui paʻa, paʻa kiʻekiʻe
• Nā hemahema: ka haki nui ʻana, ke kūpaʻa ʻole o ka mea hoʻoheheʻe, ke kūpaʻa wela
• Hoʻohana: pepa kākau, mea pāʻani, pahu mīkini uila, ipu ʻaina styrofoam
2. Polycarbonate (PC)
• Waiwai: Nā thermoplastics amorphous
• Nā Pōmaikaʻi: ikaika kiʻekiʻe a me ka modulus elastic, ikaika hopena kiʻekiʻe, laulā mahana hana ākea, transparency kiʻekiʻe a me ka hoʻoluʻu manuahi, HDT kiʻekiʻe, kūpaʻa luhi maikaʻi, kūpaʻa maikaʻi i ke aniau, nā ʻano uila maikaʻi loa, ʻono ʻole a ʻala ʻole, ʻinoʻino i ke kino kanaka, olakino a me ka palekana, emi haʻahaʻa o ka hoʻoheheʻe ʻana a me ke kūpaʻa maikaʻi o ka dimensional
• Nā Pōʻino: Hiki i ka hoʻolālā huahana maikaʻi ʻole ke hoʻoulu maʻalahi i nā pilikia koʻikoʻi kūloko
• Noi:
√ Nā mea uila: Nā CD, nā kuapo, nā hale lako home, nā pūkuniahi hōʻailona, nā kelepona
√ Kaʻa: nā pale, nā papa hoʻolaha, ke aniani palekana
√ Nā ʻāpana ʻoihana: nā kino kāmela, nā hale mīkini, nā mahiole, nā goggles luʻu, nā aniani palekana
3. Nā kūlana ʻē aʻe
• ʻO ka hoʻoili ʻana o ka mālamalama o PS he 92%, ʻoiai no PC he 88%.
• ʻOi aku ka maikaʻi o ka paʻakikī o PC ma mua o PS, he palupalu ka PS a hiki ke haki maʻalahi, ʻoiai ʻoi aku ka paʻa o PC.
• Hiki i ka mahana hoʻololi wela o PC i 120 degere, ʻoiai ʻo PS ma kahi o 85 degere wale nō.
• He ʻokoʻa loa nō hoʻi ke kahe o nā mea ʻelua. ʻOi aku ka maikaʻi o ke kahe o PS ma mua o PC. Hiki iā PS ke hoʻohana i nā puka kiko, ʻoiai ʻo PC ke pono nei i kahi puka nui.
• He ʻokoʻa loa ke kumukūʻai o nā mea ʻelua. I kēia manawamaʻamauʻOi aku ke kumukūʻai o PC ma mua o 20 yuan, ʻoiai he 11 yuan wale nō ke kumukūʻai o PS.
ʻO ka palaki PS e pili ana i ka ClassⅠplastic e komo pū ana me Styrene i loko o ke kaulahao Macromolecular, a me Styrene a me Copolymers. Hiki ke hoʻoheheʻe ʻia i loko o nā hydrocarbons Aromatic, Chlorinated hydrocarbons, Aliphatic Ketones a me nā esters, akā hiki ke pehu wale i ka acetone.
Ua kapa ʻia ʻo PC ʻo Polycarbonate, i hoʻopōkole ʻia ʻo PC, he mea thermoplastic amorphous, ʻaʻohe kala, moakaka, a ʻaʻohe ona ʻano. Loaʻa ka inoa mai ka hui CO3 kūloko.
Manaʻolana wau e hiki iā ia ke kōkua i nā mea kūʻai aku e hoʻomaopopo i ke kumu o ka ʻokoʻa o ke kumukūʻai ma waena o PC a me PS. Manaʻolana nō hoʻi au e makaʻala nā mea kūʻai aku i ke koho ʻana i nā kukui, mai hoʻopunipuni ʻia e ke kumukūʻai. Ma hope o nā mea a pau, loaʻa iā ʻoe ka mea āu e uku ai.
ʻO Liper ma ke ʻano he mea hana kukui ʻoihana, ua paʻakikī loa mākou i ke koho ʻana i nā mea, no laila hiki iā ʻoe ke koho a hoʻohana me ka hilinaʻi.
Ka manawa hoʻouna: Mei-31-2024
