Hiki ke hoʻoholo ʻia ke ʻano o ka pepa PP mai nā ʻano he nui. No laila he aha ke kūlana kūʻai o ka pepa PP?

Mai ka hana kino a hiki i ka nānā ʻana

Pono nā pepa PP kiʻekiʻe e loaʻa nā waiwai kino maikaʻi loa, a he nui nō hoʻi nā hōʻailona, ​​​​e like me ke ʻala ʻole, ʻaʻohe mea ʻawahia, waxy, hiki ʻole ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe maʻamau, haʻahaʻa ka omo ʻana, a me nā waiwai insulation uila maikaʻi loa. Haʻahaʻa ka nui, paʻakikī maikaʻi, insulation dielectric maikaʻi. Haʻahaʻa ka helu omo. Haʻahaʻa ka permeability mahu wai. Paʻa kemika maikaʻi. Panalāʻau Kaua Anti-Kepani.
E nānā i ke ʻano

ʻO ka nānā ʻana i ke ʻano o ka pepa PP e pili ana i ka palahalaha o ka pepa, ke ʻano like o ke kala, ka hoʻopau ʻana o ka ʻili, ka ʻokoʻa o ke kala, ke kihi lawa ʻole, ka ʻāpana, ka mānoanoa, a me nā mea ʻē aʻe. Ma ke ʻano laulā, hiki i nā pepa maikaʻi ke piʻi i kahi kiʻekiʻe ma kēia mau hōʻailona.

He aha ka ʻokoʻa ma waena o ka pepa PP a me ka pepa PVC?

1. ʻOkoʻa kala:
ʻAʻole hiki ke moakaka ka mea PP. Ma keʻano laulā, hoʻohana ʻia ke kala mua (ke kala maoli o ke ʻano PP), hina beige, keʻokeʻo ponoʻī, a pēlā aku. Loaʻa i ka PVC nā kala momona, me ka hina ʻeleʻele, ka hina māmā, ka beige, ka moakaka a pēlā aku.

2. ʻOkoʻa ke kaumaha:
ʻOi aku ka haʻahaʻa o ka nui o ka pepa PP ma mua o ka pepa PVC, ʻoi aku ka nui o ka nui o ka PVC, a kaumaha ka PVC. ʻO ka nui o ka pepa PP ma ke ʻano maʻamau he 0.93, ʻo ka nui o ka pepa PVC: 1.58-1.6, a me ka nui o ka pepa PVC moakaka: 1.4.

3. Ke ahonui ʻana i ka waikawa-kumu:
ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o ka pepa PVC i ka waikawa a me ka alkali ma mua o ka pepa PP, akā he palupalu a paʻakikī kona ʻano, kūpaʻa ia i ka radiation ultraviolet, hiki ke hoʻomanawanui i ka loli o ke aniau no ka manawa lōʻihi, ʻaʻole hiki ke lapalapa, a he ʻawaʻawa iki. Eia nō naʻe, ʻaʻole pale ka pepa PP i nā kukuna ultraviolet, a e loli ke kala ke hōʻike ʻia iā ia no ka manawa lōʻihi.

4. ʻOkoʻa o ka mahana:
ʻO ka pae piʻi mahana o PP he 0 ~ 80 degere Celsius, a ʻo ka pae o PVC he 0 ~ 60 degere Celsius.

5. Ka laulā o ka noi:
Hoʻohana nui ʻia ka pepa PP i nā lako hana kūpaʻa waikawa a me ka alkali, nā lako palekana kaiapuni, nā kinoea ʻōpala, nā lako hana mālama wai ʻōpala, ka hale holoi, ka lumi maʻemaʻe, ka hale hana semiconductor a me nā lako ʻoihana e pili ana, ma waena o ia mau pepa mānoanoa PP i hoʻohana nui ʻia i ka papa stamping, ka papa stamping, a pēlā aku.
