He aha te Poly(propylene glycol) CAS 25322-69-4?

Ko te poly(propylene glycol) he polymer he wai kore tae ki te kowhai marama. He wairewa i roto i te wai (he iti te taumaha ngota) me nga whakarewa pararopi penei i te ketone aliphatic me te waipiro, engari karekau e rewa i roto i te ether me te nuinga o te waiwaro aliphatic. Ka whiwhihia ma te whakamaaramatanga o te propylene oxide me te propylene glycol i raro i te pehanga teitei, i te aroaro ranei o te whakakorikori waikawa.

Taupānga

1. Ko nga raupapa PPG he wairewa i roto i nga whakarewa pararopi penei i te toluene, te waihano, te trichloroethylene, me etahi atu. Ko te PPG200, 400, me te 600 he wairewa ki te wai, he whakahinuhinu, he whakahinuhinu, he whakahinuhinu, he whakakino, he tohu antistatic. Ka taea te whakamahi PPG-200 hei dispersant mo nga pigments.

2. I roto i nga mahi whakapaipai, ka whakamahia te PPG400 hei whakamomori, hei whakangawari, hei whakahinuhinu.

3. Ka whakamahia te Poly(propylene glycol) hei kaikawe anti-foaming i roto i nga paninga me nga hinu waipēhi, he kaihoko antifoaming i roto i te rapa waihanga me te tukatuka latex, he whakamahana me te whakamahana mo nga wai whakawhiti wera, me te whakapai ake i te pokey.

4. Ka whakamahia te poly(propylene glycol) hei takawaenga mo te esterification, etherification, me te polycondensation tauhohenga.

5. Ka whakamahia te poly(propylene glycol) hei kaihoko tuku, hei kaiwhakarewa, hei taapiri mo nga hinu waihanga, he taapiri mo nga wai tapahi wairewa, hinu roera, hinu hiko, hinu wera teitei, me nga hinu o roto me waho mo te rapa.

6. PPG-2000~8000 he pai whakahinuhinu, anti-foaming, wera me te haupapa ātete me ētahi atu āhuatanga;

7. Ko te PPG-3000~8000 te nuinga e whakamahia ana hei waahanga o te polyether whakakotahi hei whakaputa i nga kirihou polyurethane foam;

8. Ka taea te whakamahi tika i te PPG-3000 ~ 8000 ranei i muri i te esterification ki te whakaputa i nga plasticizers me nga hinu;
