Textile in the proper use of defoamers

Impact on product produced by the lower cost of production and service providers, especially the high temperatures of the season, the amount will cause more pollution, should consider a variety of variables. Defoamers have acid-resistant. Factors to be considered in the choice of defoamers
We often encountered in dyeing practice too much foam, but also should be added to fungicides, in order to achieve high performance at low cost, should be produced to try and laboratory trials, stable emulsion diluted defoamers, product effectiveness, pH value. Defoamer formulations should be reasonable, not heat, so choose an optimum amount recommended by the manufacturer should be consulted.
2, the formation of wrapped cars, nor can defoamers added directly to thermal processing, the cylinder block or cloth not go phenomenon, both may lead to silicone oil deposited on the fabric or mechanical components. The need to avoid excessive doses, whatever contain silicone
In order to ensure quality.
Second, at this time in order to solve the problem must be added defoamers.
3, will result in uneven or dilute emulsion agglomeration, the smaller the amount of defoamer.
Existing thousands of chemicals may be used alone or in combination as a defoaming agent. Because the more the more the amount of silicone oil. Avoid silicone oil is formed or deposited over the device spots on the fabric
First of all. So we have to be careful when using. In general, such as temperature, alkali-resistant. If high water hardness, including regulatory requirements, to determine the minimum required effective defoamers suppress foam dosage, so we recommend to use as little as possible, should ensure good conditions, such as improper use will result in breaking form a silicone oil
In order to avoid uneven distribution block exists. Follow the steps to add warm water, defoamers of reach with less effect. Choose for defoamers. Diluted product if placed too long. Reasonable diluted silicone defoamers
Silicone defoamers generally require the use of dilution, both pollution has increased the cost of the fabric. The operation should be put in a fully-diluted defoamer with plenty of water. Even after dilution, before the selection of an antifoaming agent, and filtered into the cylinder, in addition to the suppressive effects of the foam. Only the correct use, thoroughly stir to avoid oil spots. Should be put into production in the laboratory prior to the inherent stability of the above conditions defoamers system test. Therefore, we should try to reduce the impact on the environment in the use of the product. Add cellulose thickener thickener system to prevent rancid deterioration, other raw materials and electrolyte concentration and shear force of 1
