PVC Khoom Txheej Txheem

1. Kev npaj cov khoom siv raw: PVC feem ntau pib los ntawm ethylene thiab chlorine, thiab vinyl chloride monomer yog tsim los ntawm chlorinating ethylene, thiab ethylene kuj tuaj yeem muab rho tawm los ntawm cov yas khib nyiab, khib nyiab roj hmab, cov ntaub ntawv pov tseg thiab lwm yam pov tseg, thiab ces chlorinated. . Npaj PVC raw cov ntaub ntawv yuav tsum tau kuaj xyuas kom lawv ua tau raws li cov qauv zoo.

2. Polymerization: Kev tsim cov PVC feem ntau yog siv cov txheej txheem ntawm polymerization. Nyob rau hauv lub polymerizer, monomers ntxiv rau tej yam kev mob tshwm sim, ua rau ib tug polymerization cov tshuaj tiv thaiv uas synthesizes lub monomers rau hauv polymers. Nyob rau hauv cov txheej txheem polymerization, tej yam kev mob tshwm sim, xws li kub, lub sij hawm, catalyst, siab, thiab lwm yam, yuav tsum tau tswj xyuas kom zoo ntawm cov khoom tiav.

3. Coagulant ntxiv: Thaum lub sij hawm PVC polymerization cov tshuaj tiv thaiv, ib co coagulant yuav tsum tau ntxiv nyob rau hauv thiaj li yuav tsim polymer hais nyob rau hauv lub polymerizer, yog li ntawd cov polymer hais xwb ncav cuag qhov xav tau loj thiab zoo.

4. Lim thiab ntxuav: Tom qab polymerization, cov polymer yuav tsum tau lim thiab ntxuav kom tshem tawm impurities, gels thiab lwm yam impurities, kom cov polymer ua dawb huv. Lim thiab ntxuav yog cov kauj ruam tseem ceeb los xyuas kom meej qhov zoo ntawm cov khoom tiav.

5. Kev ziab thiab ua tiav: Tom qab pom thiab ntxuav, PVC flakes tau qhuav, thiab tom qab ntawd ua tiav raws li daim ntawv thov sib txawv thiab cov khoom tsim tsim. Cov txheej txheem ua haujlwm xws li extrusion, calendering, txhaj tshuaj molding, tshuab moulding, thiab lwm yam.

6. Kev soj ntsuam zoo: Hauv cov txheej txheem ntawm kev ua cov khoom siv PVC, kev tshuaj xyuas nruj yog yuav tsum tau xyuas seb qhov zoo ntawm cov khoom tiav raws li qhov yuav tsum tau ua. Kev tshuaj xyuas zoo suav nrog kev tshuaj xyuas qhov muag, kev kuaj xyuas lub cev, tshuaj xyuas tshuaj, thiab lwm yam.
