ʻO ka ʻokoʻa ma waena o ka PVC palupalu a me ka PVC paʻakikī

Hiki ke hoʻokaʻawale ʻia ka PVC i ʻelua mau mea: PVC paʻakikī a me PVC palupalu. ʻO ka inoa ʻepekema o PVC he polyvinyl chloride, ʻo ia ka ʻāpana nui o ka plastic a hoʻohana pinepine ʻia e hana i nā huahana plastic. He makepono a hoʻohana nui ʻia. ʻO ka PVC paʻakikī no kahi o ʻelua hapakolu o ka mākeke, ʻoiai ʻo ka PVC palupalu no hoʻokahi hapakolu. No laila, he aha nā ʻokoʻa ma waena o ka PVC palupalu a me ka PVC paʻakikī?

1. Nā ʻano like ʻole o ka palupalu a me ka paʻakikī

ʻO ka ʻokoʻa nui loa ma ko lākou ʻano paʻakikī like ʻole. ʻAʻohe mea palupalu i loko o ka PVC paʻakikī, he palupalu maikaʻi kona, maʻalahi ke hana, ʻaʻole palupalu, ʻaʻohe mea ʻawahia a haumia, lōʻihi ka manawa mālama, a he waiwai nui kona no ka hoʻomohala ʻana a me ka hoʻohana ʻana. Ma ka ʻaoʻao ʻē aʻe, aia nā mea palupalu me ka palupalu maikaʻi, akā he palupalu a paʻakikī hoʻi i ka mālama ʻana, no laila ua kaupalena ʻia kona hoʻohana ʻana.

1. ʻO kanā pae noihe ʻokoʻa

Ma muli o kona maʻalahi maikaʻi, hoʻohana pinepine ʻia ka PVC palupalu no ka ʻili o nā lole papaʻaina, nā papahele, nā kaupaku, a me ka ʻili; Hoʻohana nui ʻia ka polyvinyl chloride paʻakikī i nā paipu PVC paʻakikī, nā mea hoʻopili, a me nā ʻaoʻao.

3. ʻO kanā ʻanohe ʻokoʻa

Mai ka ʻano o nā hiʻohiʻona, he mau laina hoʻolōʻihi maikaʻi ko ka PVC palupalu, hiki ke hoʻolōʻihi ʻia, a he kūpaʻa maikaʻi i nā mahana kiʻekiʻe a me nā mahana haʻahaʻa. No laila, hiki ke hoʻohana ʻia e hana i nā uhi papa ʻaina moakaka. ʻAʻole ma mua o 40 degere ka mahana hoʻohana o ka PVC paʻakikī, a inā kiʻekiʻe loa ka mahana, hiki ke hōʻino ʻia nā huahana PVC paʻakikī.

4. ʻO kanā waiwaihe ʻokoʻa

ʻO ka nui o ka PVC palupalu he 1.16-1.35g/cm³, ʻO ka helu omo wai he 0.15 ~ 0.75%, ʻo ka mahana hoʻololi aniani he 75 ~ 105 ℃, a ʻo ka helu hoʻemi hoʻoheheʻe ʻana he 10 ~ 50 × 10-³cm/cm. ʻO ka PVC paʻakikī maʻamau he anawaena o 40-100mm, nā paia o loko laumania me ke kūpaʻa haʻahaʻa, ʻaʻohe unahi, ʻaʻohe mea ʻawahia, ʻaʻohe haumia, a me nā waiwai kūpaʻa i ka pala. ʻAʻole ʻoi aku ka mahana o ka hoʻohana ʻana ma mua o 40 degere, no laila he paipu wai anuanu. Kūpaʻa maikaʻi i ka ʻelemakule a pale ahi.
