1. Yiyiphi imisebenzi ye-latex powder ephinda ihlakazwe kwi-mortar?
Impendulo: I-latex powder ehlaziywayo ibunjwe emva kokusasazeka kwaye yenza njenge-adhesive yesibini yokuphucula ibhondi; i-colloid ekhuselayo ifunxwa yinkqubo yodaka (ayiyi kuthiwa itshatyalaliswe emva kokubunjwa. Okanye ihlakazwe kabini); i-polymerization ebunjiweyo I-resin ebonakalayo isasazwa kulo lonke inkqubo yodaka njengento yokuqinisa, ngaloo ndlela ikwandisa ukudibanisa komdaka.
2. Yiyiphi imisebenzi ye-latex powder ephinda ihlakazwe kwidaka elimanzi?
Impendulo: Ukuphucula ukusebenza kolwakhiwo; ukuphucula ukumanzi; ukwandisa i-thixotropy kunye ne-sag resistance; ukuphucula umanyano; ukwandisa ixesha lokuvula; ukwandisa ukugcinwa kwamanzi;
3. Yiyiphi imisebenzi ye-latex powder enokuchithwa kwakhona emva kokuba udaka lunyangelwe?
Impendulo: ukwandisa amandla okuqina; ukwandisa amandla okugoba; ukunciphisa imodyuli elastiki; ukwandisa ukukhubazeka; ukwandisa ubuninzi bezinto eziphathekayo; ukwandisa ukumelana nokunxiba; ukwandisa amandla okubambisana; Ine-hydrophobicity egqwesileyo (yongeza i-hydrophobic rubber powder).
