White latex is a water-soluble adhesive, due to the advantages of good film-forming properties, easy to use, cheap and so on. Was mainly used in wood, machinery and other industries. In the process of production and use of white emulsion, artificial latex in the mixing, pouring, flow and filtration, often due to air mixing leads to a large number of foam generation, if there is no addition of white emulsion defoamer, then these bubbles will spread out not only affect the quality of the white emulsion, but also affect the progress of the work. These large amounts of foam so that the major glue manufacturers are very headache. Some glue factories will try Baozhongbao white latex defoamer to clean up the foam. Let's learn more about glue foam.

  First of all, we first share a small story about the glue foam it. Mr Mo is the person in charge of a white glue factory in Dongguan. Recently, Mr Mo in the white latex processing and production process, found that the surface of the white latex has a lot of foam spread up, because of the foam problem led to the lack of utilization of equipment and reduce product quality, for the glue subsequent to the finished product canning has caused a great impact.

  Why the white latex production process the foam?

  White latex belongs to the surfactant, can change the surface tension. When white latex is used, it is easy to produce foam when it comes into contact with air.

  White latex in the production process because of the need to add some chemical raw materials, and the chemical reaction between these chemical raw materials, resulting in the emergence of foam.

  What the white latex production in a large number of foam will have harm?

  1, the air in the foam will hinder the dispersion of the pigment or filler, adding difficulties to the production operation.

  2, too much foam will reduce the equipment utilisation rate, affecting the quality of the product.

  3、Stable foam will increase the volume of the litre barrel, make the weight of the barrel uneven, increase the cost of packaging.

  4、Foam will affect the degree of product blending.

  5、Terminal use of adhesives when the foam is too much, affecting the bonding strength.

  6、When you open the lid of the barrel when selling, you can see many bubbles inside, which affects the aesthetics and reduces the trust of customers.

  How to solve the white latex foaming problem?

  Use white latex defoamer and other chemicals to react with the foam in the white latex, so that the foam in the white latex is removed.
