Nā huahana

Pōmaikaʻi: ʻO Rigid PVC kekahi o nā mea i hoʻohana nui ʻia.ʻO ka mea PVC kahi ʻano mea ʻole crystalline.

Ma ka hoʻohana maoli, hoʻohui pinepine ʻia nā mea PVC me nā stabilizers, lubricants, auxiliary processing agents, pigments, impact agents a me nā mea hoʻohui ʻē aʻe.

ʻAʻole hiki ke hoʻomālamalama ʻia nā mea PVC, ikaika kiʻekiʻe, kū i ka wā a me ke kūpaʻa geometric maikaʻi loa.

He kūpaʻa ikaika ka PVC i nā mea hoʻoheheʻe, nā mea hoʻemi a me nā waikawa ikaika.Eia nō naʻe, hiki ke hoʻopau ʻia e nā ʻakika oxidizing concentrated, e like me ka sulfuric acid concentrated a me ka nitric acid concentrated, a ʻaʻole kūpono no ka hoʻopili ʻana i nā hydrocarbons aromatic a me nā hydrocarbons chlorinated.

Nā pōʻino: He ʻilihune loa nā hiʻohiʻona kahe o PVC, a he haiki loa kona pae kaʻina.ʻO ka mea nui, ʻoi aku ka paʻakikī o ka hana ʻana i nā mea PVC me ke kaumaha molekala nui (pono nā mea e hoʻohui i ka lubricant no ka hoʻomaikaʻi ʻana i nā ʻano kahe), no laila hoʻohana mau ʻia nā mea PVC me ke kaumaha liʻiliʻi.

He haʻahaʻa loa ka emi ʻana o PVC, maʻamau 0, 2 -- 0, 6%.

He maʻalahi ka PVC e hoʻokuʻu i ke kinoea ʻawaʻawa i ke kaʻina hana.
