He aha ka ʻokoʻa ma waena o PE, PP, ABS?

ʻO ka mea hoʻopili uea o ke kaula mana ka mea nuiPE (polyethylene), PP (polypropylene) a me ABS (acrylonitrile-butadiene-styrene copolymer).

ʻOkoʻa kēia mau mea i ko lākou mau waiwai, hoʻohana a me nā ʻano.
1. PE (polyethylene) :
(1) Nā hiʻohiʻona: ʻO ka PE he resin thermoplastic, me ka meaʻawaʻawaʻole a me ka pōʻinoʻole, ke kūpaʻa haʻahaʻa haʻahaʻa, nā waiwai insulation uila maikaʻi a me nāʻano'ē aʻe. Loaʻa iā ia nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa a me ka ikaika conductive kiʻekiʻe, no laila hoʻohana pinepine ʻia e like me kahi mea insulating no ka uea uila kiʻekiʻe a me ke kaula. Eia kekahi, loaʻa i nā mea PE nā hiʻohiʻona uila maikaʻi a hoʻohana nui ʻia i nā uea coaxial a me nā kaula e koi ana i ka capacitance wire haʻahaʻa.
(2) Noi: Ma muli o kāna mau waiwai uila maikaʻi loa, hoʻohana pinepine ʻia ʻo PE i ka uea a i ʻole ka hoʻopili ʻana i ka uwea, ʻikepili uea insulation mea, a me nā mea ʻē aʻe.

2. PP (polypropylene):
(1) Nā hiʻohiʻona: ʻO nā hiʻohiʻona o ka PP he elongation liʻiliʻi, ʻaʻohe elasticity, lauoho palupalu, wikiwiki kala maikaʻi a humuhumu maʻalahi. Eia naʻe, ʻano ʻino kona huki ʻana. ʻO ka hoʻohana ʻana i ka mahana wela o PP ʻo -30 ℃ ~ 80 ℃, a hiki ke hoʻomaikaʻi ʻia kona mau hiʻohiʻona uila e ka huʻa.
(2) Noi: Ua kūpono nā mea PP no nā ʻano uea a me nā kaula āpau, e like me ke kaula mana a me ka uea uila, a hoʻokō i nā koi ikaika haʻihaʻi UL, hiki ke loaʻa ʻole nā ​​hono.

3. ABS (acrylonitrile-butadiene-styrene copolymer):
(1) Nā hiʻohiʻona: ʻO ka ABS kahi thermoplastic polymer material structure me ka ikaika kiʻekiʻe, ka paʻakikī maikaʻi a me ka hana maʻalahi. Loaʻa iā ia nā mea maikaʻi o ka acrylonitrile, butadiene a me styrene ʻekolu monomers, i loaʻa iā ia ke kūpaʻa corrosion kemika, ke kūpaʻa wela, ka paʻakikī o ka ʻili kiʻekiʻe a me ka elasticity kiʻekiʻe a me ka paʻakikī.
(2) Hoʻohana: Hoʻohana pinepine ʻia ʻo ABS i nā noi e koi ana i ka ikaika kiʻekiʻe a me ka paʻakikī, e like me nā ʻāpana kaʻa, nā uila uila, a me nā mea ʻē aʻe.

I ka hōʻuluʻulu ʻana, loaʻa i ka PE, PP a me ABS ko lākou pono ponoʻī a me nā hiʻohiʻona noiʻi i nā mea hoʻopili uea o nā uwea mana. Hoʻohana nui ʻia ʻo PE i ka uea a me ka hoʻokaʻawale ʻana i ke kaula no kāna mau waiwai hoʻonaninani uila maikaʻi loa a me ke kūpaʻa haʻahaʻa haʻahaʻa. Ua kūpono ʻo PP no nā ʻano uea a me ke kaula no ka palupalu a me ka wikiwiki o ka waihoʻoluʻu maikaʻi; Hoʻohana ʻia ʻo ABS, me kona ikaika kiʻekiʻe a paʻakikī, e hoʻokaʻawale i nā ʻāpana uila a me nā laina mana e pono ai kēia mau ʻano.

Pehea e koho ai i nā mea pono PE, PP a me ABS e like me nā koi noi o ke kaula mana?

Ke koho ʻana i nā mea pono PE, PP a me ABS, pono e noʻonoʻo piha i nā koi noi o ke kaula mana.
1. ABS mea:
(1) Mechanical waiwai: ABS mea he kiʻekiʻe ka ikaika a me ka paakiki, a hiki ke ku i ka nui mechanical ukana.
(2) Ka nani o ka ʻili a me ka hana ʻana i ka hana: He maikaʻi nā mea ABS a me ka hana ʻana i ka hana, kūpono ia no ka hana ʻana i ka hale laina mana a i ʻole nā ​​ʻāpana plug me nā koi kiʻekiʻe a me ka hana maikaʻi.

2. PP mea:
(1) Ke kū'ē i ka wela, ka paʻa kemika a me ka palekana o ke kaiapuni: Ua ʻike ʻia ka mea PP no kona kūpaʻa wela maikaʻi, kūpaʻa kemika a me ka pale ʻana i ke kaiapuni.
(2) Hoʻopili uila: He maikaʻi ka hoʻopili uila ʻo PP, hiki ke hoʻohana mau ʻia ma 110 ℃-120 ℃, kūpono no ka ʻāpana insulation kūloko o ka laina mana a i ʻole he mea hoʻoheheʻe no ka uea.
(3) Nā kahua noi: Hoʻohana nui ʻia ʻo PP i nā lako o ka hale, nā lako hoʻopihapiha, nā lako, nā huahana mahiʻai, nā huahana hale a me nā māla ʻē aʻe, e hōʻike ana he ākea ākea ka pili a me ka hilinaʻi.

3, PE mea:
(1) Ka pale ʻana i ka corrosion: ʻO ka pepa PE he kūpaʻa maikaʻi loa i ka corrosion a hiki ke noho paʻa i loko o nā media kemika e like me ka waikawa a me ka alkali.
(2) Insulation a me ka haʻahaʻa wai absorption: PE pepa he maikai insulation a me ka haʻahaʻa wai absorption, hana PE pepa i ka mea maʻamau i ka uila a me ka uila kahua.
(3) ʻO ka maʻalahi a me ka pale ʻana i ka hopena: ʻO ka pepa PE he ʻoluʻolu maikaʻi a me ka pale ʻana i ka hopena, kūpono no ka pale o waho o ka laina mana a i ʻole he mea sheath no ka uea e hoʻomaikaʻi ai i kona kūpaʻa a me ka palekana.

Inā makemake ka laina mana i ka ikaika kiʻekiʻe a me ka nani o ka honua, ʻo ka mea ABS paha ke koho maikaʻi loa;
Inā makemake ka laina mana i ka wela wela, ke kūpaʻa kemika a me ka pale ʻana i ke kaiapuni, ʻoi aku ka maikaʻi o ka mea PP;
Inā makemake ka laina mana i ka corrosion resistance, insulation a me ka haʻahaʻa wai haʻahaʻa, ʻo ka mea PE kahi koho kūpono.
