Water treatment defoamer is generally divided into two categories of silicone and polyether, according to the different properties of wastewater, water treatment defoamer used is also different, according to the composition is roughly divided into silicone, silicon polyether, fatty acid, polyether and higher alcohols; According to the form of solid defoamer, powder defoamer, liquid defoamer (oily liquid and emulsion liquid).
Category Name
Silicone defoamer for water treatment
Active ingredients: polysiloxane, dispersant, emulsifier, surfactant easy to disperse, defoaming speed, foam inhibition lasting, strong foam inhibition, does not affect the various technical parameters of the system, will not cause secondary pollution of water.
Description:
This product is milky white or yellowish oil-in-water emulsion; Non-volatile matter 16±1%;PH value:6.5-7.5; Stability (3000 rpm/20 min): no delamination; Ionic characteristics: non-ionic; dispersibility: can be well dispersed in water.
Scope of application
This product is specially designed for water treatment process, defoaming speed, foam inhibition lasting, used in pharmaceutical, paper, leather, printing and dyeing, municipal sewage biological treatment process and chemical cleaning and other foaming system. This product uses the environmental protection formula, the product non-toxic harmless, does not affect the bacterial reproduction. It can also be used for defoaming of oil drilling fluid mud system.
Efficacy performance
1. Low surface tension, high activity, strong defoaming.
2. No change in heat resistance and high temperature, low volatility.
3. Good chemical stability, chemical inertia, does not react with other substances, can be used under harsh conditions.
4. No physiological toxicity, no effect on the use of the system.
5. has the functions of eliminating and inhibiting foam, and the foam inhibiting time can reach more than 48 hours.
How to use:
It is recommended to use 1-3 times diluted with water or solvent (also available foaming liquid) before use; ② Concentrated dripping, feeding or spraying at the place where the foam is concentrated, or directly at the mouth of the pool with good sewage fluidity. Recommended usage is 30-300PPM.
How to use
1. Solid defoamer
Hang it at the outlet of wastewater treatment circulating pump or wastewater discharge outlet, let it dissolve slowly, prevent foam from generating, so as to achieve defoaming effect.
2. Powder defoamer
The use of powder defoamer is relatively simple. When the foam in the biochemical treatment tank is large, the defoamer is sprinkled to make it quickly defoaming, but the personnel should keep adding it.
3. Liquid defoamer
The liquid defoamer is generally added to the treated pool before discharge, but the effect is not good during aeration treatment. It is better to dilute the spray when using it. It can be diluted to 100-1000 times and continuously sprayed with a pump. The effect is very obvious.
Storage method
This product is non-toxic, non-flammable and explosive, stored in a cool, sheltered place, sealed preservation. Storage period of one year, no obvious stratification. Storage beyond the best use period indicated on the label does not mean that the product cannot be used any longer. However, in order to ensure the quality of the product in this case, it is necessary to re-examine the relevant properties of the product.
