Mechanism of Defoamer for Metal Cutting Fluid -- 2021-01-15

Generally speaking, pure water and pure surfactants do not blister because their surface and interior are uniform, so it is difficult to form an elastic film. Even if they are formed, they are unstable and disappear instantaneously. However, in the presence of surfactant in the solution, the hydrophilic and hydrophobic groups in the molecules are adsorbed by the bubble wall due to the intermolecular force, forming a regular arrangement. The hydrophilic group is toward the water phase, and the hy ...

Special Defoamer for Washing Powder to Solve the Problem of Washing Powder Foam. -- 2021-01-14

Of course, washing powder is indispensable in daily necessities. What is the reason why we should use detergent defoamer instead of washing powder and laundry fluid? The more foam, the better the washing effect. The less foam will reduce the decontamination ability. This view is one-sided. The decontamination ability of laundry products depends on the variety, proportion and quantity of active substances and the performance of detergent aids.How does the foam of laundry detergent come into being ...

The Role of Defoamer in Common Softening Problems in Printing and Dyeing Production -- 2021-01-13

1. The hydrophilicity of the fabric decreasesGenerally, the film structure problems, the lack of water absorption genes after silicone oil film formation, and the sealing of water absorption centers such as hydroxyl group of cellulose fiber, carboxyl group and amino group of wool cause the decrease of water absorption.Treatment method: anionic, nonionic film and hydrophilic silicone oil should be selected as far as possible.2. Dark spotsThe causes are as followsThe oil stain on the fabric is not ...

Introduction of Multifunctional Finishing Agent -- 2021-01-12

Fabric finishing is to apply a finishing agent on the fabric, which can change the surface properties of the fabric, thus giving the fabric special functions. For example, hydrophobic and oleophobic finishing is to treat the fabric with a finishing agent with low surface tension, change the surface characteristics of the fiber, so that the surface of the fabric is not easy to be moistened and spread by water or oil, so as to achieve the purpose of hydrophobic and oleophobic finishing. Antifoulin ...

What are the Types of Food Grade Defoamers and Their Classification Characteristics -- 2021-01-08

1. Advantages of natural oils (i.e. soybean oil, corn oil, etc.): easy source, low price,Simple to use; disadvantages: if the storage is not good, it is easy to deteriorate, so that the acid value increases, and it is toxic to fermentation.2. There are many kinds of polyether defoamers, mainly including the following: A. GP defoamer: it is made by addition polymerization of propylene oxide or mixture of ethylene oxide and propylene oxide with glycerol as the starting agent. GP defoamer has poor ...

Characteristics and Selection of Amino Silicone Oil -- 2021-01-07

Amino silicone oil is a basic component used in textile softener. It has the best adsorption, compatibility and emulsification. Using a mixer or homogenizer, the amino silicone oil is easily emulsified into a stable and transparent microemulsion by the appropriate surfactant. It can be used alone or combined with other organosilicon or organic softeners to form a special softener, which is suitable for the softening finishing of various textiles.Basic introductionAmino silicone oil is a basic co ...

Basic Knowledge of Silicone Rubber -- 2021-01-05

How to Establish the Compatibility of Coupling Agent between Organic and Inorganic Substances. -- 2020-12-30

The common function of coupling agent is to establish compatibility between organic and inorganic materials. For example, to improve the dispersion of nano calcium carbonate in polymer, coupling agent and surface treatment are needed. The introduction of organic groups on the surface of inorganic materials makes it much more compatible with polymers and reduces the problems of migration, precipitation and agglomeration.This is similar to block polymer or graft polymer (such as graft maleic anhyd ...
