Polyether defoamer

Product description

Polyether defoamers are a type of polyether polyol mixture obtained through a special process involving different starting agents and epoxy compounds such as ethylene oxide, propylene oxide, and butylene oxide, under the action of a catalyst. Due to the presence of both hydrophilic and hydrophobic groups in their molecular structure, they can disrupt the double electron layer in foam, thereby exhibiting defoaming capabilities, while also demonstrating outstanding anti-foaming performance.

Technical index

Product feature

Easily dispersible in water.

Especially in high COD, high pollution water, and acidic or alkaline environments, it can quickly eliminate foam.

Fast defoaming speed and long-lasting foam suppression.

Application area

Leachate landfills, furnace slag wastewater, white water from paper manufacturing, desulfurization from power plants, oxidation smelting, biochemical wastewater, etc.

Application Method

This product cannot be diluted with water. Diluting it with water may cause layering, reducing its defoaming effect and ultimately increasing usage costs. 

Based on factors such as viscosity, temperature, and stirring conditions of the foaming system, select an economical dosage in ppm units.

A metering pump can be used to directly add the defoamer to the system requiring defoaming. It is recommended to add the defoamer to areas where it can easily disperse, with an initial dosage of 10 ppm per ton of foaming liquid.

The optimal addition point, dosage, addition method, and dilution ratio should be determined by the customer through on-site testing based on actual conditions.

Precautions

Packaged in 25kg, 50kg, 200kg plastic drums or 1000kg IBC drums.

Sealed storage at room temperature (5°C to 40°C) with a well-ventilated, dry environment away from direct sunlight.  

Freeze at temperatures below 0°C. If frozen, dissolve and stir thoroughly; this will not affect its performance.

Validity period 12 months (under suitable temperature conditions, unopened).
