Iyini i-Poly(propylene glycol) CAS 25322-69-4?

I-Poly (propylene glycol) iyi-polymer enokubonakala koketshezi olungenambala kuya koluphuzi olukhanyayo. Iyancibilika emanzini (isisindo esiphansi sama-molecule) kanye nezinyibilikisi eziphilayo ezifana nama-aliphatic ketones nama-alcohols, kodwa ayincibiliki ku-ether kanye nama-hydrocarbon amaningi e-aliphatic. Itholakala ngokujiya kwe-propylene oxide kanye ne-propylene glycol ngaphansi kwengcindezi ephezulu noma lapho kukhona i-catalyst ene-acidic.

Isicelo

1. Uchungechunge lwe-PPG luyancibilika ezincibilikisini eziphilayo ezifana ne-toluene, i-ethanol, i-trichloroethylene, njll. I-PPG200, i-400, ne-600 ziyancibilika emanzini futhi zinezakhiwo zokugcoba, zokuhlanza, zokwehlisa isithunzi, kanye nezokulwa nama-static. I-PPG-200 ingasetshenziswa njengesihlanzisi semibala.

2. Ezimonyweni, i-PPG400 isetshenziswa njengesithambisi, isithambisi, kanye nesithambisi.

3. I-Poly (propylene glycol) isetshenziswa njenge-ejenti yokulwa nokugqwala ezimbozweni nasemafutheni e-hydraulic, i-ejenti yokulwa nokugqwala ekucutshungulweni kwerabha yokwenziwa kanye ne-latex, i-refrigerant kanye ne-coolant yokudlulisa ukushisa, kanye ne-viscosity improver.

4. I-Poly (propylene glycol) isetshenziswa njengesixhumi se-esterification, etherification, kanye ne-polycondensation reactions.

5. I-Poly (propylene glycol) isetshenziswa njenge-ejenti yokukhulula, i-ejenti yokuncibilikisa, isithasiselo samafutha okwenziwa, isithasiselo samanzi okusika ancibilikayo emanzini, amafutha e-roller, amafutha e-hydraulic, amafutha okugcoba ashisa kakhulu, kanye nezinto zokugcoba zangaphakathi nezangaphandle zerabha.

6. I-PPG-2000~8000 inokugcoba okuhle kakhulu, ilwa nokukhipha amagwebu, ukumelana nokushisa nesithwathwa kanye nezinye izakhiwo;

7. I-PPG-3000~8000 isetshenziswa kakhulu njengengxenye ye-polyether ehlanganisiwe ukukhiqiza ipulasitiki ye-polyurethane foam;

8. I-PPG-3000~8000 ingasetshenziswa ngqo noma ngemva kokwenziwa kwe-esterification ukukhiqiza ama-plasticizer kanye nezinto zokugcoba;
