PVC pombi (PVC-U pombi) yakaoma PVC pombi, yakagadzirwa nePVC resin ine stabilizer, lubricant uye imwe inopisa inotsikirira extrusion molding, ndiyo yekutanga kugadzirwa uye kuiswa pombi yepurasitiki.PVC-U pombi ine yakasimba corrosion kuramba, nyore bonding, yakaderera mutengo uye yakaoma manyorerwo.Nekudaro, nekuda kwekudonhedza kwePVC-U monomer uye zvinowedzera, inokodzera chete kune yemvura sisitimu iyo tembiricha yekufambisa isingapfuure 45 ℃.Plastic pombi inoshandiswa kudhiraivha, tsvina, makemikari, kudziyisa uye kutonhora mvura, chikafu, ultra-pure zvinwiwa, madhaka, gasi, mhepo yakamanikidzwa uye vacuum system application.
Iyo ine yakanaka tensile uye inomanikidza simba: asi kuchinjika kwayo hakuna kunaka semamwe mapaipi epurasitiki.
Kuramba kwemvura yakadzika: madziro ePVC-U pombi akatsetseka, uye kushomeka kwemvura kudiki kwazvo.Iyo roughness coefficient inongova 0.009, uye huwandu hwayo hwekutakura mvura hwakakwirira 20% kupfuura iyo yesimbi yakakandwa pombi yedhayamita imwechete, uye 40% yakakwirira kupfuura iyo yekongiri pombi.
Yakanakisa corrosion kuramba uye kusagadzikana kwezvinodhaka: PVC-U pombi ine yakanakisa asidhi inodzivirira, alkali inodzivirira uye corrosion kuramba.Iyo haina kukanganiswa nehunyoro uye ivhu pH, uye haidi chero anti-corrosion kurapwa kana pombi yakaiswa.
Nekuomeswa kwemvura kwakanaka: kuiswa kwePVC-U pombi kune mvura yakanaka yekudzivirira, ingave yakabatanidzwa neadhesive kana rubber ring.
Kuruma humbowo: PVC-U machubhu haasi sosi yezvinovaka muviri uye saka haatanirwe nerodent kurwisa.Maererano neongororo yakaitwa neNational Health Foundation kuMichigan, makonzo haarume pombi yePVC-U.
Performance bvunzo: yekurapa nguva, shrinkage rate, kupatsanura simba, tensile pfuma kubvisa simba, kugadzikana kwekupisa, nguva inoshanda, nguva yekuchengetedza, kuburitswa kwezvinhu zvinokuvadza.
Nzira yekugadzira
Raw zvinhu + gadziriro yebetsero → kusanganisa → kufambisa nekudyisa → kumanikidzira kudya → Cone-type twin-screw extruder → extrusion mold → saizi sleeve → pfapfaidza vacuum yekugadzika bhokisi → kunyura mvura inotonhorera → inki inodhinda → crawler tirakita → banga rekusimudza → pombi stacking rack → kupedza chigadzirwa kuyedzwa uye kurongedza.
PVC inogona kukamurwa kuita nyoro PVC uye yakaoma PVC.
Yakaoma PVC accounts inosvika 2/3 yemusika, uye yakapfava PVC account ye1/3.
Yakapfava PVC inowanzo shandiswa pauriri, sirin'i uye nedehwe, asi nekuti yakapfava PVC ine plasticizer (uyu ndiwowo mutsauko pakati pePVC yakapfava uye yakaoma PVC), kuita kwemuviri hakuna kunaka (sezvo pombi dzemvura dzinoda kutakura imwe dzvinyiriro yemvura, PVC yakapfava haina kukodzera kushandiswa), saka chiyero chekushandisa kwayo ishoma.
Hard PVC haina plasticizer, saka iri nyore kuumba, yakanaka yemuviri zvivakwa, saka ine yakakura kukura uye kukosha kwekushandisa.Mukugadzirwa kwezvinhu zvePVC, zvimwe zvinowedzera zvinosungirwa kuwedzerwa, senge stabilizer, plasticizer uye zvichingodaro.Kana zvese zvinongedzo zvekuchengetedza kwezvakatipoteredza zvichishandiswa, iyo PVC pombi zvakare isiri-chepfu uye isinganakidze kuchengetedzwa kwezvakatipoteredza zvigadzirwa.
