PVC inogona kukamurwa kuita zvinhu zviviri: PVC yakaoma uye PVC yakapfava. Zita resainzi rePVC ipolyvinyl chloride, inova ndiyo inonyanya kushandiswa mupurasitiki uye inowanzoshandiswa kugadzira zvigadzirwa zvepurasitiki. Haidhuri uye inoshandiswa zvakanyanya. PVC yakaoma inoumba zvikamu zviviri muzvitatu zvemusika, nepo PVC yakapfava ichiumba chikamu chimwe muzvitatu. Saka, musiyano uripi pakati pePVC yakapfava nePVC yakaoma?
- Madhigirii akasiyana ekupfava nekuoma
Musiyano mukuru uri mukusiyana kwavo kwekuomarara. PVC yakaoma haina zvinopfavisa, inochinjika zvakanaka, iri nyore kugadzira, uye haikurumidzi kupwanyika, haina chepfu uye haina kusvibiswa, inogara kwenguva refu ichichengetwa, uye ine kugadzirwa kwakanaka uye kukosha kwayo. PVC yakapfava, kune rumwe rutivi, ine zvinopfavisa zvine kupfava kwakanaka, asi inowanzo pwanyika uye yakaoma kuchengetedza, saka kushanda kwayo kwakaganhurirwa.
- Iyomafomu ekushandisazvakasiyana
Nekuda kwekuchinjika kwayo kwakanaka, PVC yakapfava inowanzo shandiswa pamusoro pemachira etafura, pasi, padenga, uye dehwe; polyvinyl chloride yakaoma inonyanya kushandiswa mumapaipi ePVC akaomarara, zvigadziko, uye maprofiles.
3. Iyohunhuzvakasiyana
Kubva pamaonero ehunhu, PVC yakapfava ine mitsetse yakanaka yekutambanudza, inogona kuwedzerwa, uye inodzivirira kupisa kwakanyanya uye kwakaderera. Nokudaro, inogona zvakare kushandiswa kugadzira machira etafura akajeka. Tembiricha yekushandisa yePVC yakaoma kazhinji haipfuure madhigirii makumi mana, uye kana tembiricha yacho yakanyanya, zvigadzirwa zvePVC zvakaoma zvinogona kukuvara.
4. Iyozvivakwazvakasiyana
Kuwanda kwePVC yakapfava ndeye 1.16-1.35g/cm³, Mwero wekunyudzwa kwemvura ndeye 0.15~0.75%, tembiricha yekuchinja kwegirazi ndeye 75~105 ℃, uye mwero wekupwanya kwemuumbi ndeye 10~50 × 10-³.cm/cm. PVC yakaoma inowanzova nedhayamita ye40-100mm, madziro emukati akatsetseka asina simba rakawanda, haana chikero, haana chepfu, haana kusvibiswa, uye haapindi ngura. Tembiricha yekushandisa haisi kupfuura madhigirii makumi mana, saka ipombi yemvura inotonhora. Inodzivirira kukwegura zvakanaka uye inodzivirira moto.
