Chlorinated polyvinyl chloride (CPVC) chinhu chepolymer chinowanikwa mushure mekuwedzera kuchena kwePVC.Zvinhu zvepanyama uye zvemakemikari zvinoshanduka zvakanyanya: nekuwedzera kweklorini yezvinyorwa, kusawirirana kwemaketani emakemikari kunowedzera uye crystallinity inoderera;iyo polarity yeketani yemamorekuru inowedzera, iyo intermolecular simba inowedzera, tembiricha yekupisa yekupisa inowedzera zvakanyanya, uye ma mechanical properties anowedzerwa.
CPVC iri nani kupfuura PVC mukuramba kwemamiriro ekunze, kuramba kuchembera uye kudzoreredza moto.Semuenzaniso, mushure mekuchenesa, muganhu weokisijeni indekisi yePVC ichakwira kubva ku45 ~ 49 kusvika> 70 (ine 67% CPVC chlorine), uye huwandu hweutsi uye kabhoni yakasara mumurazvo ichaderedzwa zvakanyanya.Chlorination process yakakanganisa maitiro ezvigadzirwa.Iyo chlorine yemukati yePVC inogona kusvika 73% mushure mekunatswa.
Kazhinji nemvura chikamu kumiswa muitiro, pashure kusanganisa PVC resin, ne chlorination, filtration, washing, CPVC kugadzirwa neutralization, kuomeswa muitiro wapera, mhando PVC poda zvinhu zvemuti kusarudzwa kwakakosha zvikuru, kunyanya kukanganisa machining kugadzikana, kugadzikana kwekupisa) , kusarudzwa kwePVC resin raw material yakasununguka, dehwe rakatetepa sezvinobvira, chimiro chechidimbu chakanaka chezvakanaka.Iyo yakawanda chlorine yemukati ndeye 63% ~ 67%.Kuramba kwayo kwemamiriro ekunze, kushorwa kwecorrosion, kuramba kuchembera uye kupisa kwemoto kunongoerekana kwaitika kuri nani kupfuura zvakajairika PVC resin.Iyo chlorine yemukati inowedzera, saka vica softening point tembiricha yakawedzera zvakanyanya, 35 ℃ yakakwira kupfuura PVC resin, tembiricha inodzivirira kupisa kusvika 130 ℃, inokodzera pombi dzinodzivirira kupisa uye mafittings nemaplate (senge pombi dzemvura inopisa, majoini, kudzivirira kupisa. makemikari emidziyo uye tangi yekuchengetedza).
UPVC yakaoma PVC.Chinhu chakagadziridzwa chinogadzirwa nekuwedzera imwe chiyero chezvinowedzera zvakagadziridzwa pahwaro hwePVC poda yemuti."U" is Unplasticized (Unplasticized), saka musiyano mukuru pakati pe UPVC nePVC uye PVC yakapfava ndeyokuti hapana plasticizer inowedzerwa, yakawanda calcium powder, high mechanical simba rezvinyorwa, zvakakodzera kugadzirwa kwevhavha uye mapaipi.
CPVC inonzi chlorinated polyvinyl chloride.Zvichienderana nePVC resin, CPVC inowedzera chlorine yemukati muPVC zvinhu neimwe nzira, kazhinji kubva pa63 kusvika 69%, kuitira kuti ivandudze kudzivirira kupisa, asidhi, alkali, munyu uye oxidant corrosion yechinhu, uye kuvandudza kupisa. deformation tembiricha uye michina zvinhu zvezvinhu.
CPVC inowedzera chlorine yemukati yePVC resin nenzira dzemakemikari, saka mutengo wezvinhu zveCPVC resin wakakwira.Muchikamu chekupedzisira, zvimwe zvakagadziridzwa zvinoda kuiswa kune chigadzirwa jekiseni kana extrusion, zvichikonzera kudhura kwakanyanya kwezvinhu zvakagadziridzwa zveCPVC.Mutengo wekutengesa weCPVC wakagadziridzwa zvimedu muChina kazhinji uri pamusoro pe20,000 / tani.
Nekuda kwemutengo wepamusoro weCPVC, hazvigoneke kuti chinyorwa ichi chishandiswe zvakanyanya seUPVC.Parizvino, CPVC inonyanya kushandiswa mumapombi ekurwisa moto, pombi dzinodzivirira kemikari uye pombi dzemvura inopisa.
