PVC inogona kukamurwa kuita zvinhu zviviri: yakaoma PVC uye yakapfava PVC. Zita resainzi rePVC ndiro polyvinyl chloride, inova chikamu chikuru chepurasitiki uye chinowanzoshandiswa kugadzira zvigadzirwa zvepurasitiki. Yakachipa uye inoshandiswa zvakanyanya. Yakaoma PVC inoverengera ingangoita zvikamu zviviri muzvitatu zvemusika, nepo PVC yakapfava ichiverengera chikamu chimwe muzvitatu. Saka, ndeupi musiyano pakati pePVC yakapfava uye yakaoma PVC?
- Madhigirii akasiyana ekupfava uye kuoma
Musiyano mukuru uri mukuoma kwavo kwakasiyana. Yakaoma PVC haina zvinyoro-nyoro, ine kuchinjika kwakanaka, iri nyore kuumba, uye haisi nyore brittle, isina chepfu uye isina kusvibiswa, ine nguva yakareba yekuchengetedza, uye ine budiriro huru uye kukosha kwekushandisa. PVC yakapfava, kune rumwe rutivi, ine zvinyoro-nyoro zvine kupfava kwakanaka, asi inogara kune brittleness uye kuoma mukuchengetedza, saka kushanda kwayo kunogumira.
- Theapplication rangeszvakasiyana
Nekuda kwekuchinjika kwayo kwakanaka, PVC yakapfava inowanzoshandiswa pamusoro pemachira etafura, pasi, sirin'i, uye dehwe; Hard polyvinyl chloride inonyanya kushandiswa mumapaipi akaoma ePVC, mafittings, uye profiles.
3. Themaitirozvakasiyana
Kubva pakuona kwemaitiro, PVC yakapfava ine mitsetse yakanaka yekutambanudza, inogona kuwedzerwa, uye ine kuramba kwakanaka kune yakakwirira uye yakaderera tembiricha. Naizvozvo, inogona zvakare kushandiswa kugadzira machira epatafura akajeka. Tembiricha yekushandiswa kwePVC yakaoma kazhinji haipfuure madhigirii makumi mana, uye kana tembiricha yakanyanyisa, zvigadzirwa zvePVC zvakaoma zvinogona kukuvara.
4. Thepropertieszvakasiyana
Kuwanda kwePVC yakapfava ndeye 1.16-1.35g/cm ³, Kunyura kwemvura kuri 0.15 ~ 0.75%, tembiricha yegirazi ndeye 75 ~ 105 ℃, uye shrinkage yekuumbwa i10 ~ 50 × 10- ³cm/cm. Yakaoma PVC kazhinji ine dhayamita ye40-100mm, yakatsetseka madziro emukati ane kushomeka kwekushomeka, isina kuyera, isina chepfu, isina kusvibiswa, uye inodzivirira marara. Iyo tembiricha yekushandisa haina kupfuura 40 madhigirii, saka iri pombi yemvura inotonhora. Kuramba kwakanaka kwekuchembera uye kudzoreredza moto.
