PVC resin yekudiridza pombi
PVC resin yekudiridza pombi,
pombi yekudiridza mbishi, pvc yekudiridza pombi,
PVC kudiridza pombi:
(1) PVC kudiridza pombi ine yakanakisa asidhi kuramba, alkali kuramba uye ngura kuramba, izvo chaizvo akakodzera makemikari indasitiri.Rusvingo pamusoro pePVC yekudiridza pombi yakatsetseka.Kupokana kwemvura kudiki, uye roughness coefficient inongova 0.009, iyo yakaderera pane mamwe mapaipi.Pasi pekuyerera kwakafanana, iyo dhayamita yepombi inogona kuderedzwa.Kupikiswa kwemvura kudzvinyirirwa, kupikisa kwekunze kwekumanikidza uye kupikisa kwePVC pombi dzekudiridza dzakakwirira kwazvo, iyo inokodzera piping engineering pasi pemamiriro akasiyana siyana.Iyo yakachipa uye inoshandiswa zvakanyanya.
(2) PVC yekudiridza pombi inogona kunyatso tevera kukura kwembeu kuti uone kudiridza kwemazuva ano.Mvura inoshandiswa pakudiridza inogona kusarudzwa zvichienderana nehunyoro hwezvirimwa nevhu.
(3) PVC kudiridza pombi ndiyo zvikuru zvachose anogona kwakavakirwa hunhu hwazvino kweather kuwana yakarurama mvura uye fetiraiza kuti mudzi zvirimwa kudiridza unyanzvi.Izvi zvinogona kuderedza basa remaoko.
(4) PVC yekudiridza pombi inogona kutakura mvura yekudiridza inonzwisisika zvinoenderana nekukura kwezvirimwa, izvo zvinogona kuve nechokwadi chekudiridza panguva uye kwakakodzera kwezvirimwa uye kuisa hwaro hwakasimba hwekuvandudza goho rezvirimwa.
(5) Mapombi ekudiridza anoshandiswa zvakanyanya mumadhorobha nekumaruwa mukati nekunze kwemvura, kuvandudzwa kwemvura yekumaruwa, kudiridza minda yekurima, pombi yekuparadzira brine yemunyu nemakemikari indasitiri, kutakurwa kwemvura yeindasitiri yezvemvura, kufefetedza kwemugodhi, mvura yekugezera, sprinkler. kudiridza nemamwe mapurojekiti makuru nemadiki.
Polyvinyl Chloride (PVC) iine mutsara thermoplastic resin inogadzirwa ne polymerization yevinyl chloride monomer.Nekuda kwekusiyana kwezvinhu zvakabikwa, kune nzira mbiri dzekugadzira vinyl chloride monomer calcium carbide process uye petroleum process.Sinopec PVC inotora maitiro maviri ekumisa, zvichiteerana kubva kuJapan Shin-Etsu Chemical Company neAmerican Oxy Vinyls Company.Chigadzirwa chine yakanaka makemikari corrosion kuramba, yakanakisa magetsi ekudzivirira zvivakwa uye yakanaka kugadzikana kwemakemikari.Iine yakakwira chlorine yemukati, iyo nyaya ine yakanaka retardance yemoto uye yekudzima-inodzima zvinhu.PVC iri nyore kugadzirisa ne extrusion, jekiseni kuumba, calendering, kuvhuvhuta kuumbwa, compressing, kuumbwa kuumbwa uye kuumbwa kwekupisa, nezvimwe.
