Yintoni iPolyethylene Glycol CAS 25322-68-3?

I-Polyethylene glycol ineempawu ezahlukeneyo ngokuxhomekeke kubunzima bayo bemolekyuli, ukusuka kulwelo lwe-viscous olungenambala nolungenavumba ukuya kwizinto eziqinileyo. Abo banobunzima be-molecular of 200-600 balulwelo kwiqondo lobushushu begumbi, ngelixa abo banobunzima bemolekyuli ngaphezulu kwe-600 ngokuthe ngcembe baba semi-solid. Iipropati nazo ziyahluka kunye ne-avareji ye-molecular weight. Ukusuka kulwelo lwe-viscous olungenambala nolungenavumba ukuya kwi-waxy solid.

Isicelo

I-Polyethylene glycol isetyenziswa ngokubanzi kwiimveliso zokuthambisa kunye namayeza. Ngenxa yeempawu ezigqwesileyo ze-polyethylene glycol, kubandakanywa ukunyibilika kwamanzi, ukungaguquguquki, ukungabi namandla komzimba, ubulali, ukuthambisa, kunye nokukwazi ukumanzisa, ukuthambisa, kunye nokubonelela nge-aftertaste emnandi eluswini.
