Piav qhia
Saib xyuas
Qhov txheej txheem suav nrog cov kauj ruam nram qab no: siv ib qho calcium carbide acetylene txoj kev tsim khoom thiab ib qho fixed bed synthesis reactor los tsim vinyl acetate; siv vinyl acetate ua raw material, methanol ua solvent, azobisisobutyronitrile ua initiator, siv free radical solution polymerization mode, thiab siv anhydrous low-alkali belt alcoholysis mode los tsim polyvinyl alcohol; thiab ua crushing, pressing, drying, packaging thiab lwm yam kom tau txais cov khoom.
Txhais Nploog
Cov tsis: Polyvinyl Alcohol (PVA)
Tawj hauv kawm: -[CH2CH(OH)]n
Cov tsis muaj rau hwm:
- Cov nyob rau hwm: Cov txoj kev polyvinyl alcohol mus yooj hais tawm ntawv. Cov resin polyvinyl alcohol (PVA) yog cov tsis muaj degree of alcoholysis peb 95% mus yooj hais tawm ntawv no, thiab cov resin polyvinyl alcohol (PVA) yog cov tsis muaj degree of alcoholysis peb 99.5% mus yooj hais tawm ntawv lub sis 95℃.
- Cov tsis muaj qhia lwm: Polyvinyl alcohol tsis muaj qhia lwm los yog hais tawm, tsis muaj teb chaw lawm 40℃, los yog hais tawm 160℃, thiab tsis muaj qhia lwm los yog hais tawm 220℃ los yog hais tawm tej hluas tawm, thiab cov tshaj plaws water, acetic acid, acetaldehyde thiab crotonaldehyde.
- Cov tsis muaj rau hwm: PVA tsis muaj rau hwm yog cov tsis muaj rau hwm weak acid, weak base los yog hwm organic solvent, thiab cov tsis muaj rau hwm los yog hwm oil resistance.
- Cov tsis muaj storage: PVA yog cov polymer low viscosity, thiab cov tshaj plaws ntawv no yog stable los yog hais tawm ntawv no. Lub tshaj plaws ntawv no tsis muaj rau hwm los yog hais tawm storage.
- Tsim ntau noj: Mus yuav tsum los ntawv PVA, PVA yog mus tsim ntau noj. Ntawm noj li cas thiab hais txog, lub noj li cas thiab hais txog, muaj lub qhov kev rau kawg, cov xovxwm li cas thiab hais txog, thiab cas thiab hais txog, muaj qhov kev nyob rau lwm thiab hais txog, thiab qhov kev nyob rau lwm thiab hais txog. Lub noj li muaj qhov kev nyob rau lwm thiab hais txog, muaj qhov kev nyob rau lwm thiab hais txog, muaj qhov kev nyob rau lwm thiab hais txog, thiab qhov kev nyob rau lwm thiab hais txog.
Kev nyob rau lwm:
PVA yog muaj qhov kev nyob rau lwm thiab hais txog, muaj qhov kev nyob rau lwm thiab hais txog. Lub qhov nyob rau lwm li muaj qhov kev nyob rau lwm thiab hais txog, muaj qhov kev nyob rau lwm thiab hais txog, muaj qhov kev nyob rau lwm thiab hais txog, thiab muaj qhov kev nyob rau lwm thiab hais txog.
