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
First prepare a 5% calcium chloride aqueous solution: Weigh 50 g of anhydrous calcium chloride with a 1% balance, add 950 ml of water to shake well, and set aside. In a 10 ml graduated test tube, use a dropper to add 5 ml of emulsion, and then add 1 ml of 5% calcium chloride solution. Pay attention ... read more
The emulsion for architectural coatings should develop in the direction of ultra-durability and versatility. Such as actively researching and developing fluorine-containing emulsions, acrylic silicone emulsions, vinyl acetate-tertiary carbonate copolymer emulsions, room temperature cross-linking emu... 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
