He aha nā ʻano o ka Polyvinyl Chloride (PVC)?
ʻO kekahi o nā waiwai koʻikoʻi o Polyvinyl Chloride (PVC): Density: He paʻa loa ka PVC i hoʻohālikelike ʻia me ka hapa nui o nā plastics (kikoʻī koʻikoʻi a puni 1.4) Economics: Loaʻa koke ka PVC a makepono ke kumu kūʻai. Paʻakikī: Kūlana maikaʻi ʻo PVC paʻa no ka paʻakikī a me ke kūpaʻa. Ikaika: Loaʻa i ka PVC paʻa ka ikaika tensile maikaʻi loa. ʻO Polyvinyl Chloride kahi mea "thermoplastic" (e kūʻē i ka "thermoset"), e pili ana i ke ʻano o ka pane ʻana o ka plastic i ka wela.
