China Supplier Organic Silicone Emulsion Antifoaming
Defoamer LS-8030 (For wastewater treatment)
Description:
It is a durable silicone antifoam emulsion specially designed to be used for controlling foam in normal and high temperature aqueous system.
It is exceptionally easy to use and it displays superior dispersibility in both non-ionic and anionic aqueous foaming media and it won’t form free surface oil or non-dispersed particles.
It is extremely stable and easy to handle.
Product Properties
control the foam efficiently under low concentration
good and long-term defoaming ability
Fast defoaming speed, long time antifoam, high efficient
Low dosage, non-toxic, non-corrosive and without adverse side effects
Disperse easily in the water, have a good compatibility with liquid product, and demulsify float oil difficultly.
Not only inhibit excessive bubble on the surface, but also eliminate dispersed bubbles

This antifoam has found utility in many industrial applications such as :
--Textile sizing, scouring, dyeing and finishing
--Rubber and latex processing
--Chemical and Petroleum processing
--Water treatment system
--Agrichemical formulations
--Adhesive and glue manufacturing
--Chemical specialty formulations (such as alkaline cleaners and heavy-duty detergents)
--Paper making and finishing
--Metal etching solution
--Leather tanning.
How to use:
It is preferably added before foam formation although it will also acts as a defoamer to destroy existing foam.
Generally, only a very low concentration of 0.06 - 0.1 g/L of it is enough for the foam control application. However, the optimum level is really dependent upon many factors such as temperature, bath composition, viscosity or agitation of the foaming system. It is also dependent on the requirement of the defoaming effectiveness hence to increase or decrease the level and obtain the most economical concentration.
When evaluating our antifoam:
--We recommend that 0.06 - 0.1 g/L of as-received product be evaluated initially.
--Adjust use levels according to the observed performance.
Use our antifoam as received or dilute first with water.
--Mix the antifoam well before use
--Dilution: Mix 3 to 10 parts of diluent to 1 part antifoam; stir gently until a uniform mixture is reached
--For long-term bulk stability of dilution, use a thickened water diluent
--Don’t use hot water to dilute it
Generrally speaking, the best dosage needs test to confirm.
