Polyvinyl Chloride (PVC) resin yepombi
Polyvinyl Chloride (PVC) resin yepombi,
PVC nokuda kwemvura pombi, PVC Pipe Raw Material, PVC resin yeHose, PVC resin yekudiridza,
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.
Application
PVC ndeimwe yeanonyanya kushandiswa thermoplastic resins.Inogona kushandiswa kugadzira zvigadzirwa zvine kuomarara kwepamusoro uye kusimba, senge pombi uye zvishongedzo, magonhi ane profiled, mahwindo uye mapepa ekurongedza.
Inogonawo kugadzira zvigadzirwa zvakapfava, senge mafirimu, mashizha, waya dzemagetsi netambo, floorboards uye synthetic dehwe, nekuwedzera kweplasticizers.

Polyvinyl Chloride (PVC) ndeimwe yeanonyanya kushandiswa thermoplastic zvinhu zvinozivikanwa kumaindasitiri mazhinji.PVC pombi inoratidzira yakasarudzika uye inowirirana mhando ine yunifomu zvivakwa zvichiita kuti ive sarudzo inosarudzika yevagadziri uye dzimba dzetsika.Iyo inopikisa zvakanyanya kune acids, alkalis, alcohols, uye zvimwe zvakawanda zvinopisa zvinhu.PVC masisitimu akareruka, anochinjika uye akaomarara, uye anopa kusarudzika corrosion kuramba.Nekuda kweizvi uye zvimwe zvivakwa zvemhando yepamusoro yakagadzirwa thermoplastic, iyo yekuchengetedza inogona kuwanikwa mukutanga kuisirwa uye kuenderera mberi kwemitengo yekugadzirisa yakakura.PVC pombi yakanakira akawanda maapplication anosanganisira kugovera kemikari uye dhiraivha, mvura nemarara kurapwa kwemvura, sevhisi pombi, masisitimu ekudiridza, kuunganidzwa kwemarara uye zvimwe zvakawanda zvinoshandiswa mumaindasitiri zvinosanganisira corrosive fluid kutamiswa.Chiyero chekumanikidza chinosiyana nehurongwa, saizi yepombi uye tembiricha.
