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

Mai ka hana kino e kālailai

Pono nā pepa PP kiʻekiʻe e loaʻa i nā waiwai kino maikaʻi loa, a he nui nō hoʻi nā hōʻailona, ​​​​e like me ka odorless, non-toxic, waxy, insoluble in general solvents, haʻahaʻa haʻahaʻa, a me nā waiwai insulation uila maikaʻi loa. ʻO ka haʻahaʻa haʻahaʻa, ka paʻakikī maikaʻi, ka insulation dielectric maikaʻi. Haʻahaʻa absorption rate. He haʻahaʻa ka manahu wai. Paʻa kemika maikaʻi. ʻĀpana kaua kūʻē iā Iapana.
E nānā i ke ʻano

ʻO ka nānā ʻana i ka hiʻohiʻona o ka pepa PP e pili ana i ka palahalaha o ka lau, ka like ʻana o ka waihoʻoluʻu, ka pau ʻana o ka ʻili, ka ʻokoʻa o ka waihoʻoluʻu, lawa ʻole ke kihi, ʻāpana, mānoanoa, etc.

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

1. ʻOkoʻa kala:
ʻAʻole hiki ke akaka ka mea PP. ʻO ka maʻamau, hoʻohana ʻia ka waihoʻoluʻu mua (ka waihoʻoluʻu kūlohelohe o ka ʻano PP), ka hina beige, keʻokeʻo ponoʻī, a me nā mea ʻē aʻe. He mau kala momona ka PVC, me ka hina hina, hina hina, beige, transparent a pela aku.

2. Okoa kaumaha:
He haʻahaʻa haʻahaʻa ka pepa PP ma mua o ka pepa PVC, ʻoi aku ka kiʻekiʻe o ka PVC, a he kaumaha ka PVC. ʻO ka nui o ka pepa PP he 0.93, ka nui o ka pepa PVC: 1.58-1.6, a me ka nui o ka pepa PVC maopopo: 1.4.

3. Ka hoʻomanawanui ʻana i ka ʻakika:
ʻOi aku ka maikaʻi o ka ʻakika a me ka alkali o ka pepa PVC ma mua o ka pepa PP, akā he palupalu a paʻakikī kona ʻano, kū i ka radiation ultraviolet, hiki ke hoʻomanawanui i ka hoʻololi ʻana i ke aniau no ka manawa lōʻihi, ʻaʻole hiki ke puhi ʻia, a he liʻiliʻi ka ʻona. Eia nō naʻe, ʻaʻole pale ka pepa PP i nā kukuna ultraviolet, a e loli ke kala ke ʻike ʻia iā ia no ka manawa lōʻihi.

4. ʻokoʻa wela:
ʻO ka piʻi ʻana o ka mahana o ka PP he 0 ~ 80 degere Celsius, a ʻo ka laulā o PVC he 0 ~ 60 degere Celsius.

5. Ka laulā o ka noi:
Hoʻohana nui ʻia ʻo PPsheetis i ka waikawa a me ka alkali pale lako, nā mea hoʻomalu kaiapuni, nā kinoea ʻōpala, nā mea hoʻomaʻemaʻe wai hoʻomaʻemaʻe, hale holoi holoi, lumi maʻemaʻe, hale hana semiconductor a me nā mea hana ʻoihana e pili ana, ma waena o ka PP mānoanoa i hoʻohana nui ʻia i ka pā stamping, stamping plate, etc.
