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

Ko te poly(propylene glycol) he pūmua he āhua wai kore tae ki te kōwhai mārama. Ka wairewa i roto i te wai (he iti te taumaha ngota) me ngā whakarewa waro pēnei i ngā ketone aliphatic me ngā waipiro, engari kāore e wairewa i roto i te ether me te nuinga o ngā hauwaiwai aliphatic. Ka whiwhihia mā te whakapūpū o te propylene oxide me te propylene glycol i raro i te pēhanga teitei, i te aroaro rānei o tētahi whakakorikori waikawa.

1. Ka wairewa ngā raupapa PPG i roto i ngā whakarewa waro pēnei i te toluene, te etanoru, te trichloroethylene, me ētahi atu. Ka wairewa ngā PPG200, 400, me te 600 i roto i te wai, ā, he āhuatanga whakahinuhinu, kōrero takitahi, whakakino ingoa, me te ārai i te paturopi. Ka taea te whakamahi i te PPG-200 hei whakamarara mō ngā tae.

2. I roto i ngā mahi whakapaipai, ka whakamahia te PPG400 hei whakangawari kiri, hei whakangawari, hei hinu whakahinuhinu hoki.

3. Ka whakamahia te Poly(propylene glycol) hei ārai-huka i roto i ngā paninga me ngā hinu waipēhi, hei ārai-huka i roto i te tukatuka rapa hangai me te rapa, hei hauhautanga me te whakamatao mō ngā wai whakawhiti wera, me te whakapai ake i te matotoru.

4. E whakamahia ana te poly(propylene glycol) hei takawaenga mō ngā tauhohenga esterification, etherification, me te polycondensation.

5. Ka whakamahia te Poly(propylene glycol) hei kaiwhakarewa, hei kaiwhakarewa wai, hei tāpiri mō ngā hinu hangai, hei tāpiri mō ngā wai tapahi wairewa-wai, ngā hinu roera, ngā hinu waipēhi, ngā hinu whakahinuhinu pāmahana-tiketike, me ngā hinu whakahinuhinu ā-roto, ā-waho hoki mō te rapa.

6. He pai rawa ngā āhuatanga o te PPG-2000~8000 ki te whakahinuhinu, ki te ārai i te pahuka, ki te ātete ki te wera me te huka, me ētahi atu āhuatanga anō hoki;

7. Ko te PPG-3000~8000 te nuinga e whakamahia ana hei wāhanga o te polyether whakakotahi hei hanga kirihou pahuka polyurethane;

8. Ka taea te whakamahi tika i te PPG-3000~8000, i muri rānei i te whakahāngaitanga hei whakaputa i ngā mea whakapūkara me ngā hinu whakahinuhinu;
