Indima ye-latex powder enokuchithwa kwakhona kwiimveliso zodaka

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 ikhulisa 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).

4. Yeyiphi imisebenzi ye-latex powder enokuphinda ihlakazwe kwiimveliso ezahlukeneyo zodaka olomileyo?
