Cov khoom siv raw los ua cov kav dej PVC
Cov khoom siv raw rau kev tsim cov kav dej PVC,
PVC cob, PVC los tsim cov yeeb nkab,
S-1000 polyvinyl chloride resin yog tsim los ntawm kev ncua kev kawm polymerization siv vinyl chloride monomer ua raw khoom.Nws yog ib hom polymer compound nrog ib tug txheeb ze ntom ntawm 1.35 ~ 1.40.Nws melting point yog hais txog 70 ~ 85 ℃.Tsis zoo thermal stability thiab lub teeb tsis kam, tshaj 100 ℃ los yog ntev nyob rau hauv lub hnub hydrogen chloride pib decompose, yas manufacturing yuav tsum tau ntxiv stabilizers.Cov khoom yuav tsum tau muab cia rau hauv ib qho chaw qhuav thiab ventilated warehouse.Raws li tus nqi ntawm cov yas yas, cov yas softness tuaj yeem hloov kho, thiab cov tshuaj txhuam hniav tuaj yeem tau los ntawm emulsion polymerization.
Qib S-1000 tuaj yeem siv los tsim cov zaj duab xis muag, ntawv, tawv tawv, piping, zoo li tus bar, hauv qab, cable tiv thaiv piping, ntim zaj duab xis, ib leeg thiab lwm yam khoom muag muag.

PVC kav yog tsim los ntawm extrusion ntawm raw cov ntaub ntawv PVC, thiab feem ntau ua raws li tib cov kauj ruam ntawm raug cov yeeb nkab extrusion hauj lwm:
1.Kev pub mis ntawm cov khoom siv raw hmoov hu ua resin thiab muab tub lim rau hauv PVC ntxaib ntsia hlau extruder;
2. Melting thiab cua sov hauv ntau qhov chaw extruder;
3. Extruding los ntawm ib tug tuag mus rau hauv cov yeeb nkab;
4.Kev ua kom txias ntawm cov yeeb nkab zoo li (los ntawm kev txau dej ntawm cov yeeb nkab);thiab
5. Txiav ntawm PVC kav mus rau qhov xav tau ntev.
Cov khoom siv raw rau kev tsim cov kav dej PVC yog cob thiab muab tub lim (feem ntau yog calcium carbonate, lossis feem ntau hu ua pob zeb).Cov txheej txheem sib xyaw yog 1 kilogram (kg) ntawm resin nrog 1 kilogram ntawm muab tub lim.Cov txheej txheem ntau lawm feem ntau yog automated, nrog cov neeg ua haujlwm pub cov khoom siv raw thaum pib ntawm cov txheej txheem, saib xyuas qhov kub thiab txias hauv cov txheej txheem thiab xyuas cov khoom kawg rau qhov pom tseeb tsis xws luag ua ntej ntim thiab xa mus rau cov neeg siv khoom.Txhua tus neeg ua haujlwm raug cob qhia thiab muaj peev xwm ua tau tag nrho cov haujlwm no.Cov khoom tseem ceeb rau kev tsim cov kav dej PVC yog cov khoom siv hmoov hu ua PVC resin.
