Kev siv thiab kev ceev faj ntawm PVC foaming regulators

Lub hom phiaj ntawm PVC foaming regulator: Ntxiv rau tag nrho cov yam ntxwv tseem ceeb ntawm PVC cov khoom pab ua, cov khoom tswj foaming muaj qhov hnyav molecular siab dua li cov khoom pab ua haujlwm dav dav, lub zog yaj siab, thiab tuaj yeem muab cov khoom ntau dua cov qauv cell thiab qis dua qhov ceev. Txhim kho lub siab thiab lub zog ntawm PVC yaj, yog li ua kom zoo dua qhov sib koom ua ke thiab homogeneity ntawm PVC yaj, tiv thaiv kev sib koom ua ke ntawm cov npuas, thiab tau txais cov khoom ua npuas sib xws.

Cov txiaj ntsig ntawm PVC foaming regulators:

1. Cov khoom siv pab ua ACR tuaj yeem txhawb kev yaj ntawm PVC, txhim kho qhov chaw tiav, txhim kho qhov elasticity ntawm cov yaj, thiab txhim kho qhov ntev thiab lub zog ntawm cov yaj.

2. Nws muaj txiaj ntsig zoo rau kev npog cov npuas thiab tiv thaiv kev tawg ntawm cov cell. Qhov hnyav molecular thiab koob tshuaj ntawm cov tshuaj tswj ua npuas ncauj muaj feem cuam tshuam loj rau qhov ceev ntawm daim ntawv ua npuas ncauj: nrog rau qhov nce ntawm qhov hnyav molecular, lub zog yaj ntawm PVC nce, thiab qhov ceev ntawm daim ntawv ua npuas ncauj tuaj yeem ua kom qis dua, thiab qhov nce ntawm koob tshuaj ntawm cov tshuaj tswj muaj tib qho txiaj ntsig. Tab sis qhov cuam tshuam no tsis muaj kev sib raug zoo linear. Txuas ntxiv nce qhov hnyav molecular lossis nce koob tshuaj, qhov cuam tshuam rau kev txo qhov ceev tsis pom tseeb heev, thiab qhov ceev yuav zoo li tas li.

3. Qhov hnyav molecular siab heev thiab lub zog yaj loj heev ua rau cov khoom muaj qhov ceev qis dua thiab cov qauv cell sib xws, tshwj xeeb tshaj yog rau cov khoom PVC foamed tuab.

4. Muab cov khoom muaj cov qauv cell sib xws, qhov hnyav molecular siab thiab lub zog yaj siab, qhov ceev ntawm cov khoom qis dua, thiab kev ua haujlwm zoo heev.

5. Muaj peev xwm ua kom yas zoo, yaj tau zoo heev, thiab sib haum zoo nrog cov khoom PVC, ua rau cov khoom ruaj khov dua.

6. Kev ua tau zoo heev ntawm kev ua yas, ua rau cov khoom muaj kev ua tau zoo heev thiab qhov ci ntsa iab zoo heev.

Cov kev ceev faj rau kev siv PVC foaming regulators:

Thaum siv cov tshuaj tswj kev ua npuas dej PVC, yuav tsum tau them sai sai rau cov khoom PVC uas muaj ntau theem ntawm polymerization thiab yuav tsum xaiv cov tshuaj tswj kev ua npuas dej sib txawv. Cov khoom ua npuas dej yas suav nrog: lub rooj tsavxwm ua npuas dej, lub rooj tsavxwm tuab ua npuas dej, lub rooj tsavxwm nyias ua npuas dej, lub rooj tsavxwm ntoo yas ua npuas dej, lub rooj tsavxwm ua npuas dej yas txhuas, thiab lwm yam. Xaiv cov tshuaj tswj kev ua npuas dej sib txawv. Vim tias cov khoom pab ua npuas dej PVC kuj yog cov khoom siv acrylic ester nrog cov khoom pab ua tiav, yuav tsum tau them sai sai rau qhov sib npaug ntawm cov roj nplua nyeem sab hauv thiab sab nraud ntawm cov mis thaum siv.
