Blister ntim tshuab blister polyvinyl chloride bulk polymerization txoj kev
Tso lus
Cov khoom siv polymerization yog tshwj xeeb, feem ntau yog tsim los ntawm ntsug prepolymerization kettle thiab kab rov tav polymerization kettle nrog ib tug ncej agitator. Lub polymerization yog ua nyob rau hauv ob theem. Cov monomer thiab cov neeg pib yog prepolymerized nyob rau hauv lub prepolymerization kettle rau 1 teev los tsim cov noob hais, thiab cov hloov pauv tus nqi nce mus txog 8 feem pua rau 10 feem pua, ces ntws mus rau theem ob polymerization kettle, thiab ntxiv tib tus nqi ntawm monomer li prepolymer. , txuas mus ntxiv. Thaum qhov kev hloov pauv tau nce mus txog 85 feem pua rau 90 feem pua , cov seem monomer raug tso tawm, thiab tom qab ntawd cov khoom tiav tau txais los ntawm crushing thiab sieving. Qhov loj me thiab cov duab ntawm cov resin yog tswj los ntawm kev sib tw ceev, thiab cov tshuaj tiv thaiv tshav kub yog coj tawm los ntawm reflux condensation ntawm monomer. Cov txheej txheem ntau lawm ntawm txoj kev no yog qhov yooj yim, cov khoom lag luam zoo yog qhov zoo, thiab cov nqi tsim khoom kuj tsawg.
