He aha ka ʻokoʻa ma waena o ka plastic PS a me ka PC?

No ke aha i ʻokoʻa ai nā kumukūʻai o nā kukui PS a me PC ma ka mākeke?I kēia lā, e hoʻolauna wau i nā ʻano o nā mea ʻelua.

No ke aha i ʻokoʻa ai nā 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: Amorphous polymer, Shrinkage ma hope o ka hoʻoheheʻe ʻana ma lalo o 0.6;ʻO ka haʻahaʻa haʻahaʻa e hoʻonui i ka 20% a 30% ma mua o ka mea maʻamau

• Pōmaikaʻi: kumu kūʻai haʻahaʻa, maopopo, dyeable, nui paʻa, rigidity kiʻekiʻe

• Nā pōʻino: kiʻekiʻe fragmentation, maikaʻi ʻole ka pale ʻana i ka solvent, ka pale wela

• Hoʻohana: nā mea kākau, nā mea pāʻani, nā pahu mea uila, nā lako papa styrofoam

2. Polycarbonate (PC)

• Waiwai: Amorphous thermoplastics

• Pōmaikaʻi: ikaika kiʻekiʻe a me ka elastic modulus, kiʻekiʻe hopena ikaika, ākea hana ana wela laula, kiʻekiʻe transparency a me ka noa dyeing, kiʻekiʻe HDT, maikaʻi luhi kū'ē kū'ē, maikaʻi wā kū'ē kū'ē, maikaʻi Electrical hiʻona, ono a me odorless, pōʻino i ke kino kanaka, olakino. a me ka palekana, haʻahaʻa molding shrinkage a maikaʻi dimensional paʻa

• Nā pōʻino: ʻO ka hoʻolālā huahana maikaʻi ʻole hiki ke hana maʻalahi i nā pilikia koʻikoʻi o loko

• Noi:

√ Electronics: CD, hoʻololi, hale lako hale, pūkuniahi hōʻailona, ​​kelepona

√ Kaʻa: bumpers, papa hoʻolaha, aniani palekana

√ Nā ʻāpana ʻoihana: nā kino kamera, nā hale mīkini, nā mahiole, nā maka luʻu, nā lens palekana

3. Nā kūlana ʻē aʻe

• ʻO 92% ka māmā māmā o PS, aʻo 88% no PC.

• ʻOi aku ka maikaʻi o ka paʻakikī o ka PC ma mua o PS, ʻoi aku ka maʻalahi o ka PS a hiki ke haki ʻia, ʻoiai ʻoi aku ka paʻakikī o PC.

• ʻO ka wela wela o ka PC hiki i ka 120 degere, aʻo PS wale nō ma kahi o 85 degere.

• ʻOkoʻa loa ka wai o nā mea ʻelua.ʻOi aku ka maikaʻi o ka wai o PS ma mua o ka PC.Hiki iā PS ke hoʻohana i nā puka kiko, ʻoiai pono ʻo PC i kahi puka nui.

• He okoa loa ke kumukuai o na mea elua.I kēia manawamaʻamauʻOi aku ka nui o ka PC ma mua o 20 yuan, ʻoiai ʻo PS he 11 yuan wale nō.

ʻO ka plastik PS e pili ana i ka ClassⅠplastic i loaʻa iā Styrene i ke kaulahao Macromolecular, a me Styrene a me Copolymers pū kekahi.Hiki ke hoʻoheheʻe ʻia i loko o Aromatic hydrocarbons, Chlorinated hydrocarbons, Aliphatic Ketones a me nā esters, akā hiki ke pehu wale i ka acetone.

Kapa ʻia ʻo PC ʻo Polycarbonate, i hoʻopau ʻia ʻo PC, he mea ʻeleʻele, ʻikea, amorphous thermoplastic.No loko mai ka hui CO3 ka inoa.

Manaʻo wau e hiki ke kōkua i nā mea kūʻai aku e hoʻomaopopo i ke kumu he ʻokoʻa ke kumukūʻai ma waena o PC a me PS.Manaʻolana hoʻi au e hāmama nā maka o ka poʻe kūʻai 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, koʻikoʻi mākou i ke koho ʻana i nā mea, no laila hiki iā ʻoe ke koho a hoʻohana me ka hilinaʻi.
