In a 10 ml graduated test tube, use a leaky tube to add 2 ml of emulsion, then use a dropper to add 8 ml of deionized water, shake well and place on the test tube rack, and observe whether there is any after 24 h and 48 h. If stratification, water separation, and precipitation occur, the passage doe... read more
Add 200 g of the emulsion filtered with a 120 mesh screen into a 1000ml enamel cup, place the enamel cup on the mixer, fix it with a clamp, start the stirring, adjust the speed to 4000r/min, and after stirring for 0.5 h, observe whether the emulsion is broken or flocculated. If there is no obvious f... read more
As the base material of emulsion paint, the synthesis technology has made rapid progress. Different new types of emulsions are synthesized by different polymerization methods, which can meet the new requirements of the continuous development of architectural coatings. (1) Soap-free emulsions use pol... read more
Most of the emulsions used in architectural coatings are non-crosslinked thermoplastic emulsions. Usually classified according to its monomer composition. The main varieties are:(1) Vinyl acetate homopolymer emulsion (vinegar homogenized emulsion white latex);(2) Vinyl acetate-maleate copolymer emul... read more
