Description

Technical Field

[0002] Dispersible latex powder is a water-soluble redispersible powder, which is generally synthesized through the following process. S1. Prepare protective colloid: Mix the protective colloid powder with water in a reaction kettle and heat to make glue, add defoaming agent, heat and keep warm to form a transparent viscous protective colloid, make the viscosity reach 2500MPas, and the solid content reach 19.5-20.5%. S2, prepare dispersion: put the prepared protective colloid into the mixing kettle, then add the polymer emulsion in the proportion, mix well, add defoamer and water to adjust the viscosity to 70-200MPas, solid content to 39%-42%, heat to 50-55°C, and set aside; S3, spray drying: open the spray drying tower, heat to 140-150°C at the feed inlet at the top of the spray drying tower, use a screw pump to transport the prepared dispersion to the feed inlet at the top of the spray drying tower, and atomize the dispersion into droplets with a diameter of 10 to 10 0 micron micro-droplets, quickly heat the micro-droplets with high-temperature airflow, and add isolation agent in the high-temperature airflow. When the micro-droplets are heated and become sticky, the isolation agent will be adhered to the micro-droplets in time. Subsequently, the water in the micro-droplets is quickly evaporated by the high-temperature airflow to form a gas-solid mixture; S4, cooling and separation: maintain the temperature of the airflow at the outlet of the spray drying tower at 79℃-81℃, and quickly guide the gas-solid mixture out of the outlet at the bottom of the spray drying tower, and introduce it into a large bag dust collector after cooling, and separate the powder in the airflow.
