Product Description

RK-P300 is a non-silicone defoamer grafted with functional modified polyether. It has good dispersibility, fast defoaming and strong dynamic foam suppression ability. It is mainly used for defoaming of polycarboxylate superplasticizer, power plant desulfurization, landfill leachate and water treatment, etc.
Product property:
Strong foaming inhibition and breaking foam quickly
Good dispersion
Excellent performance in the widely pH values
No negative impact on subsequent processe

Antifoam for Paper Machine:

Paper making process is an important process for paper forming. A lot of additives, such as sizing agent, retention agent, filter aid,wet strength agent,dry strength agent etc are to be used to form paper with certain performance. These additives are added in different dosing points. And it's easy to form foaming during white water circulation in closed system.

Paper machine defoamer is usually added in the points with a lot foam, for instance, underwire white water chest or white water tank. Defoamer will be added continuously in several dosing points to give full play of defoamer performance.It will not only achieve good performance but also save cost.

Defoamer For Fermentation

During the fermentation process, the foam-active substances, air and turbulences contribute the excessive foam. Generally, carbohydrates as material, are converted into sugar substrates, enzymes, starches and proteins, which promote the foam appearance.  In addition, amino acids and proteins generated by microorganism can cause large of foam activity.

Antifoam Mechanism:

1. The spread of the antifoaming agent replacesthe foaming molecules on the upperlayer of the foam bimolecular membrane, foaming a film with very low strength;
2. In the process of spreading, part of the solution of the adjacent surface layer will be taken away, reduce the stability of the foam and make it easy to destroy.

 

Foam Control Solutions For Oil And Gas

Oil and gas exploration, oil drilling, oil and gas separation, delayed coking, refining, and transportation are carried our in extremely different conditions.  Bubbles can reduce the productivity, and create the safety and environmental pollution.

Therefore, defoamers is necessary to add to reduce or eliminated to increase productivity, enhance quality.

 

Silicone based and non-silicone based antifoaming agent from Rickman optimize the production, refining, and separation of oil and gas to make sure that the petrochemical material can be extracted as purely and efficiently as possible.

 

And how to find the most suitable defoamer solutions for  water treatment, such as landifill leachate, general wastewater treatment?

1. Defoamer should be tested and verified the added volume by small trial test.

2. The amount and the method of addition depends on the foaming capacity of the water on site.  Moreover, the wastewater treatment should be a dynamic process of continuous replenishment of new wastewater.

3. The foaming force is also a dynamic fluctuation, which needs to be determined by pilot test!
