Poly (propylene glycol) CAS 25322-69-4 ni iki?

Poly (propylene glycol) ni polymer ifite ibara ritagira ibara ryijimye. Irashobora gushonga mumazi (uburemere buke bwa molekile) hamwe numuti wa organic nka alifatique ketone na alcool, ariko ntibishobora gushonga muri ether na hydrocarbone nyinshi ya alifatique. Iraboneka hamwe na kanseri ya propylene na propylene glycol munsi yumuvuduko mwinshi cyangwa imbere ya catisale acide.

Gusaba

1. Urukurikirane rwa PPG rushobora gukemuka mumashanyarazi nka toluene, Ethanol, trichlorethylene, nibindi. PPG-200 irashobora gukoreshwa nkikwirakwiza pigment.

2. Mu kwisiga, PPG400 ikoreshwa nka emollient, yoroshye, na lubricant.

4. Poly (propylene glycol) ikoreshwa nkurwego rwo hagati ya esterification, etherification, na polycondensation reaction.

6. PPG-2000 ~ 8000 ifite amavuta meza, kurwanya ifuro, ubushyuhe nubukonje nibindi bintu;

7. PPG-3000 ~ 8000 ikoreshwa cyane nkigice cya polyether hamwe kugirango ikore plastike ya polyurethane;

8. PPG-3000 ~ 8000 irashobora gukoreshwa mu buryo butaziguye cyangwa nyuma ya esterification kugirango ikore plasitike n'amavuta;
