Isicelo seMveliso

Olu hlobo lweekhemikhali lungasetyenziselwa ukuvelisa i-ester ye-acrylic ye-MPEG, kwaye yeyona nto iphambili yokwenza i-arhente yokunciphisa amanzi yesamente ye-polycarboxylate esebenza kakuhle. Ngenxa yokunyibilika kwamanzi emthonjeni, ukufuma, ukuthambisa, iimpawu zokungangenisi mzimba, iimpawu ezingenasikhuthazo kunye neziphakathi, isetyenziswa kakhulu kwishishini lezithambiso kunye namayeza.

Ngaphambili: I-Polyethylene glycol dimethyl ether (NHD-250)/ I-Polyethylene glycol dimetyl ether (NHD-500)

Okulandelayo: I-APEG kunye ne-HPEG (VPEG) kunye ne-TPEG

I-MPEG
