Nā pono o ka hoʻohana ʻana o CPE i nā kaula

No nā uea a me nā kaula uila haʻahaʻa, ua māhele nui ʻia lākou i ʻelua mau ʻāpana e like me kā lākou kumu: nā uea kūkulu a me nā uea lako uila. I loko o ke uea kūkulu, he uea ulana ʻia i uhi ʻia me ka ʻalapalapa kūlohelohe i ka makahiki 1960. Mai ka makahiki 1970, ua pani piha ʻia e nā uea plastik PVC. Ua like ke kūlana ma nā laina lako uila me ko nā laina kūkulu, kahi i noho aliʻi mua ʻia e ka ula maoli, akā ua pani nui ʻia e nā uea PVC i ka makahiki 1970. He mea ʻepekema ʻole kēia kūlana a he mea kūpono ʻole hoʻi e pili ana i ka ʻoihana uea a me nā koho a ka mea hoʻohana. I kēia mau lā, pono e hoʻololi i ke kūlana o kēia manawa o ka noho aliʻi ʻia e ka plastik PVC a pani iā ​​lākou me nā uea ula. No ka mea, he mau pono kūikawā ko nā uea ula e like me ka palupalu, ka lima maikaʻi, ʻaʻohe makaʻu i ka wela, a ʻaʻohe heheʻe, ʻaʻole hiki ke hoʻohālikelike ʻia me nā uea plastik. Ma muli o kona mau pono he nui ʻaʻohe ula synthetic, hiki ke hoʻohana nui ʻia ka CPE i ka hana ʻana i nā kaula uila hale a me nā uea palupalu ʻē aʻe no nā lako uila. Loaʻa i ka CPE nā waiwai loea piha, e like me ka pale ʻana i ke ahi maikaʻi loa a me ke kūpaʻa kiʻekiʻe o ka aila, nā waiwai kino a me nā mīkini (ʻo ia hoʻi nā waiwai mechanical), ke kūpaʻa maikaʻi i ka wela, ke kūpaʻa ozone, ke kūpaʻa i ke aniau, nā waiwai uila maikaʻi, a me ka hana hana maikaʻi. Hiki ke hoʻohana ʻia i nā lako hana rapa maʻamau, a ʻaʻole hiki i ka mea rapa ke wela. ʻAʻole e pala nā mea maka CPE ma hope o kekahi mau makahiki o ka mālama ʻana, Hiki ke mālama ʻia nā mea rapa me nā mea vulcanizing no 1-2 mau makahiki me ka ʻole o ka pala ma lalo o nā kūlana mālama maikaʻi aʻe.

I ka hōʻuluʻulu manaʻo, ʻo ka hoʻohana ʻana o CPE i ka ʻoihana uwea pūnaewele, ʻo ia hoʻi, ke pani ʻana iā CR me CPE, he ʻano ia i ka ʻoihana uwea pūnaewele. ʻAʻole wale kēia e hōʻoluʻolu i ka kūʻē ʻana o ka lako-koi o CR, e hōʻemi nui ana i ke kumukūʻai o nā huahana uwea, e hoʻomaikaʻi ana i nā pono waiwai o ka ʻoihana uwea, akā he mea nui hoʻi ia i ka hoʻomaikaʻi ʻana i ke ʻano o nā huahana uwea a me ka hoʻokō ʻana i ka ʻokoʻa o nā ʻano uwea.
