ʻO ka ʻokoʻa ma waena o PVC palupalu a me 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 mea nui o ka plastic a hoʻohana mau ʻia e hana i nā huahana plastik. He maʻalahi a hoʻohana nui ʻia. ʻO ka PVC paʻakikī e pili ana i ʻelua hapakolu o ka mākeke, ʻoiai ʻo PVC palupalu ka hapakolu. No laila, he aha nā ʻokoʻa ma waena o PVC palupalu a me PVC paʻakikī?

1. ʻO nā degere like ʻole o ka palupalu a me ka paʻakikī

Aia ka ʻokoʻa nui i ko lākou ʻokoʻa paʻakikī. ʻAʻole i loaʻa i ka PVC paʻakikī nā mea palupalu, hiki ke maʻalahi, maʻalahi ke hana, ʻaʻole maʻalahi, ʻaʻohe mea ʻawaʻawa a me ka pollution-free, lōʻihi ka mālama ʻana, a loaʻa ka waiwai nui a me ka hoʻohana ʻana. ʻO ka PVC palupalu, ma ka ʻaoʻao ʻē aʻe, aia nā mea palupalu me ka palupalu maikaʻi, akā maʻalahi i ka brittleness a paʻakikī i ka mālama ʻana, no laila ua kaupalena ʻia kona hoʻohana ʻana.

1. ʻO kapapa noihe okoa

Ma muli o kona maʻalahi, hoʻohana mau ʻia ka PVC palupalu no ka ʻili o nā pākaukau, nā papahele, nā kaupaku, a me ka ʻili; Hoʻohana nui ʻia ka polyvinyl chloride paʻa i nā paipu PVC paʻakikī, nā mea pono, a me nā ʻaoʻao.

3. ʻO kahiʻonahe okoa

Mai ka hiʻohiʻona o nā hiʻohiʻona, loaʻa i ka PVC palupalu nā laina kikoʻī maikaʻi, hiki ke hoʻonui ʻia, a he kūʻē maikaʻi i nā wela kiʻekiʻe a haʻahaʻa. No laila, hiki ke hoʻohana ʻia no ka hana ʻana i nā pāpaʻi pākaukau. ʻAʻole ʻoi aku ka mahana o ka PVC paʻakikī ma mua o 40 degere, a inā kiʻekiʻe ka wela, hiki ke hōʻino ʻia nā huahana PVC paʻakikī.

4. ʻO kawaiwaihe okoa

ʻO ka nui o ka PVC palupalu he 1.16-1.35g/cm ³, He 0.15 ~ 0.75% ka nui o ka hoʻoheheʻe ʻana o ka wai, ʻo ka mahana hoʻololi aniani he 75 ~ 105 ℃, a ʻo ka nui o ka shrinkage molding he 10 ~ 50 × 10-³.cm/cm. ʻO ka PVC paʻa maʻamau he 40-100mm ke anawaena, nā paia i loko me ka haʻahaʻa haʻahaʻa, ʻaʻohe scaling, non-toxic, pollution-free, and corrosion-resistant properties. ʻAʻole ʻoi aku ka mahana o ka hoʻohana ma mua o 40 degere, no laila he paipu wai anuanu. ʻO ke kūpaʻa ʻelemakule maikaʻi a me ka pale ahi.
