Application range of silicone defoamer 1. Textile printing and dyeing: (1) Sizing process: water emulsion type silicone defoamer, such as: silicone polyether, the amount added in the sizing tank is 0.2¬0.25g / L (2) Chemical fiber oil agent: chemical fiber oil agent is added with 0.02¬0.04% water emulsion defoamer. The chemical fiber oil formulation should contain silicone...

Method for producing and removing odor of methyl silicone oil Methyl silicone oil is one of the earliest commercialized, most widely used and most commonly used silicone polymers. The production methods of methyl silicone oil mainly include acid balance method and alkali balance method. The acid balance method is suitable for the production of low-viscosity silicone oil with a viscosity of...

The working principle of defoamer in paint 1. The generation of bubbles in paint and the principle of foam stabilization:       In the production process of paint, air will be involved to form bubbles, and some raw materials in the paint, such as surfactants and dispersants, will stabilize the bubbles.       Air bubbles will...

Application of Defoamer in concrete The workability of fresh concrete has a great influence on the pumpability, construction performance, mechanical properties and durability of hardened concrete, and the workability of fresh concrete depends largely on the air content of the concrete . In actual construction, the optimal gas content range of concrete should be determined during the trial...

Wastewater foam defoaming method There is a phenomenon of foam in sewage treatment. These foams include dense small foams and large and brittle foams. The presence of these foams will block oxygen from entering the water, seriously affecting the growth of aquatic organisms, the operation and operation of treatment processes, and the quality of the effluent water. So, under what...

Some people say that paper-plastic composite is easier than plastic-plastic composite. However, when two-component polyurethane adhesives are improperly applied to paper-plastic composites, some quality problems often occur. The most common ones are poor peel strength, blistering at the heat seal, and curl. Most of the causes of quality problems are mutual influences, such as blistering at the...

TPU hot melt adhesive film is a widely used hot melt adhesive film product. It is widely used in clothing, shoes, packaging and other fields. Its dosage is second only to EVA hot melt adhesive film. TPU hot melt adhesive film can meet customers' requirements for high viscosity, and also has good physical properties of TPU, such as good elasticity and high mechanical strength. TPU hot melt...

Medical grade adhesive (medical adhesive or medical grade adhesive) refers to the adhesive used for bonding medical devices. Many types of medical devices now rely on adhesives to assemble the agent. The modern medical device manufacturing industry requires end products to have maximum reliability and performance under many special conditions. For medical device manufacturers, when...

After 1,15, what is the cause of late attacks? Answer: After 15 days, the disinfectant is basically released 2, 33% alcohol content does not reach the concentration to kill the new crown? Answer: The alcohol content of 33% refers to the concentration in the sustained-release gel. Because ethanol has a low boiling point, most of the alcohol released is alcohol. 3. Do you have test...
