Calaamadaha Alaabta

Waa maxay Polyethylene Glycol CAS 25322-68-3?

Polyethylene glycol wuxuu leeyahay sifooyin kala duwan iyadoo ku xiran miisaankiisa molecular-ka, oo u dhexeeya dareere aan midab lahayn iyo kuwo aan ur lahayn ilaa dareereyaal shay leh. Kuwa leh miisaan molecular ah oo ah 200-600 waa dareere heerkulka qolka, halka kuwa leh miisaan molecular ah oo ka sarreeya 600 ay si tartiib tartiib ah u noqdaan kuwo nus-adkeysi ah. Sifooyinka sidoo kale way kala duwan yihiin iyadoo la eegayo celceliska miisaanka molecular-ka. Laga bilaabo dareere shay leh oo aan midab lahayn iyo mid aan ur lahayn ilaa dareere shay leh.

Codsiga

Polyethylene glycol waxaa si weyn loogu isticmaalaa warshadaha qurxinta iyo dawooyinka. Sababtoo ah sifooyinka wanaagsan ee polyethylene glycol, oo ay ku jiraan milmida biyaha, aan isbeddelin, firfircoonida jirka, jilicsanaanta, dufanka, iyo awoodda lagu qoyo, jilciyo, iyo bixinta dhadhan fiican oo maqaarka ah.
