5 mau mea maka plastik maʻamau no ka uea a me ke kaula

ʻOiai nā ʻano o ueaa me uweahe ʻokoʻa like ʻole, akā like ka hapa nui o ke ʻano o nā huahana, like nā mea maka i hoʻohana ʻia, ʻo nā mea maka maʻamau e komo pū me nā mea conductive, nā mea insulation, nā mea pale, nā mea pale, nā mea hoʻopiha, a me nā mea ʻē aʻe, a me acKaulahiki ke hoʻokaʻawale ʻia i ʻelua mau ʻano ma muli o ko lākou mau waiwai like ʻole, nā mea maka metala, e like me ke keleawe alumini, ka hui alumini, a me nā mea maka plastik. ʻO ka PVC maʻamau, PE, PP, a pēlā aku, a laila ʻo ia nā ʻano mea maka plastik 5 i hoʻohana pinepine ʻia maueaa me uwea.

1. PVC, ʻo ia ka mea maka plastik i hoʻohana pinepine ʻia i ka uea a me Uea, Hoʻohana nui ʻia ʻo PVC no ka insulation uea a me ke kaula a me nā mea pale, ʻo kēia no ka mea he nui nā waiwai pale maikaʻi o PVC hiki ke lilo i pale maikaʻi no ka uea a me ke kaula i loko, e like me ka PVC ʻaʻole maʻalahi ke puhi, ke kū'ē i ka ʻelemakule, ke kū'ē i ka aila, ke kū'ē i ka pala kemika, ke kū'ē i ka hopena, ʻO kēia mau ʻano e loaʻa ai kahi hopena hoʻokaʻawale maikaʻi a me ka pale, no laila ʻo nā mea insulation maʻamau o ka uea a me ke kaula he mau mea PVC.

2. ON(Polyethylene), ʻo kona ʻano kino he keʻokeʻo translucent waxy structure, he maʻalahi loa ka loli, hiki ke hoʻolōʻihi ʻia i kahi lōʻihi, ʻoi aku ka māmā ma mua o ka wai, ʻaʻohe ʻawahia, akā i hoʻohālikelike ʻia me PVC, he maʻalahi ke puhi ʻana o ka polyethylene. ʻOiai inā haʻalele i ke ahi, e mau ana ke ʻano e ʻā ana, he nui nā ʻano i hoʻonui ʻia o ka polyethylene, me LDPE, MDPE, HDPE, ʻo LDPE kekahi o nā density haʻahaʻa loa, i ʻike ʻia ʻo low-pressure polyethylene, he maʻalahi loa ka loli. ʻO MDPE ka medium density polyethylene, i ʻike ʻia ʻo medium pressure polyethylene, ua like ka hana a me ka polyethylene density kiʻekiʻe. Ua ʻike ʻia ʻo HDPE ʻo high pressure polyethylene, ʻoi aku ka maikaʻi o kāna hana piha, ʻoi aku ka pale ʻana i ka wela a me ka ikaika mechanical. Loaʻa i ka Polyethylene nā waiwai insulation uila maikaʻi loa a hoʻohana nui ʻia i ka insulation o nā kaula kamaʻilio.

3. ʻEVA(copolymer ethylene - vinyl acetate), he thermoplastic e like me ka rubber, ʻo kāna hana a me ka ʻike vinyl acetate (VA) he pilina maikaʻi loa, ʻo ka liʻiliʻi o ka ʻike VA e like me ka polyethylene, ʻo ke kiʻekiʻe o ka ʻike e like me nā ʻano rubber, he elasticity maikaʻi ko EVA a me ke kūpaʻa haʻahaʻa haʻahaʻa, kūpaʻa kemika. ʻOiai ke kāwili ʻia me LDPE, hiki iā ia ke hoʻomaikaʻi i ka pilikia he maʻalahi ka haki ʻana o LDPE, a hiki ke hoʻonohonoho maikaʻi ʻia a hoʻoikaika ʻia ke kūpaʻa hopena, palupalu a me ka paʻakikī, a me ka hoʻopili ʻana ma waena o ke alakaʻi a me ka insulation.

4. PP(Polypropylene), ʻo ia ka mea nona ka hapa liʻiliʻi loa ma waena o nā plastics i hoʻohana pinepine ʻia i kēia manawa, ʻoi aku ka maikaʻi o ka ikaika mechanical kiʻekiʻe, ke kūpaʻa haʻahaʻa haʻahaʻa, ke kūpaʻa ʻelemakule, me ka ikaika haki kiʻekiʻe, nā ʻano omo wai haʻahaʻa, hiki i ka mea PP ke kūpono no ke kūlana o nā mea insulation alapine kiʻekiʻe.

5. Polyester, ua hōʻike ʻia kēia ʻano mea e ke kūpaʻa kiʻekiʻe o ka haehae, ke kūpaʻa kiʻekiʻe o ka ʻaʻahu, ka elasticity kiʻekiʻe a me ka hysteresis haʻahaʻa, hiki i ka palena kiʻekiʻe o ka mahana kūpono ke hiki i 1500 degere Celsius, ʻoi aku ka nui ma mua o nā ʻano rubber thermoplastic ʻē aʻe, akā he kūpaʻa aila maikaʻi loa a me nā ʻano kūpaʻa solvent.

He loea ʻo Boying uwea mea hoʻolako me ka hui akamai, e hāʻawi ana i nā ʻano āpau uwea a me kāʻei ueaInā ʻoe e ʻimi nei uwea kūikawā, Loaʻa iā Boying kahi hopena i hoʻopilikino ʻia nou.
