yakaoma PVC extrusion, uPVC,
Rigid PVC (inozivikanwawo seuPVC) ndiyo yechitatu inogadzirwa zvakanyanya polymer.Panyaya yepurasitiki extrusions, PVC ndiyo inowanzo dhindirwa purasitiki yakaoma.Iyo ine mutengo wakaderera, ine zvivakwa zvinodzokororwa uye inogoneka kune zvese mukati nekunze kushandiswa.Izvi zvinoitayakaoma PVC extrusionsa yakakurumbira sarudzo kune dzakasiyana siyana dzekushandisa.UPVC inomirira isina purasitiki PVC uye zvinhu zvinoratidzwa nekusimba kwayo uye kusimba.Iyo zvakare ipurasitiki inochinjika zvakanyanya, yakanaka kune akawanda maapplication
Rigid PVC zvivakwa
PVC ipolymer yakaoma iyo inogona kuwedzeredzwa uchishandisa maitiro ekugadzirisa.Rigid PVC extrusions vane simba remakemikari resilience.Izvi zvinoreva kuti yakaoma PVC tubing inogona kusungirirwa zviri nyore, kunama uye kusanganiswa kwayo - yakanakira majoini mumapombi.Kupokana kwayo necorrosion kunoita extruded rigid PVC profiles, sections and trims akakodzera nzvimbo dzekunze.PVC ine zvakare yakanaka insulation zvivakwa kune yakaderera voltage magetsi ekushandisa.Kutenda kune akawanda mabhenefiti ayo,yakaoma PVC extrusions uye yakaoma PVC tubing yakashandiswa nekubudirira munzvimbo dzemukati nekunze.
Rigid PVC extrusions iri kushandiswa
Rigid PVC inoshandiswa zvakanyanya mukuvaka kwepombi dzemvura nemarara, mapombi emvura, mapombi, magata, kuvharika, madziro uye kudzivirira kwegonhi uye mafaremu emahwindo nekuda kwekunaka kwayo kwemafuta uye kugadzikana.Mukufambisa zvikumbiro uPVC inoshandiswa kunze kune mitumbi yemotokari, makaravhani uye zvikepe, uye mukati mekugadzira zvinofadza aesthetics, sezvo ichiwanikwa mune akawanda mavara uye pamusoro pekupedzisira.Muchikamu chezvitoro chekutengesa zviratidziro, mareki ekuchengetedza, mitsetse yematikiti uye poster grippers zvese zvinogadzirwa kubva kuextruded rigid PVC.
Inosanganisira thermo plasticity, kusanyungudika mumvura, peturu nedoro, kuzvimba kana kunyungudutswa kuita ether, ketone, chlorinated aliphatic hydrocarbons, uye inonhuwirira hydrocarbon, yakakwirira kuramba ngura, uye yakanaka dielectric midziyo.
Application
PVC Resin SG-3 Kushandisa ku:
1. PVC mbiri
Profiles ndiwo munda wePVC kushandiswa munyika yepamba, inenge 25% yehuwandu hwePVC inoshandiswa, kunyanya kugadzira magonhi nemahwindo uye zvinhu zvinoponesa simba, uye kushandiswa kwavo kuchiri kukuru uye kukura.
2. PVC pombi
Mapombi ePVC ndiyo yechipiri yakakura kwazvo indasitiri yekushandisa, Iyo inoshandiswa i20% yehuwandu hwekugadzira huwandu muDomestic yeChina, iyo PVC Pipe.
3. PVC firimu
Firimu rePVC rakafayerwa ndiro rechitatu hukuru hwekudyiwa, ingangoita gumi muzana yehuwandu hwekugadzira.
