Due to the action of mechanical force, ceramic glaze slurry will produce a large number of bubbles, which can easily cause glaze defects, such as pores, shrinkage glaze, orange glaze and so on.

Surfactants can reduce the interfacial energy of the system, and different types of surfactants can produce electrostatic, solvating or spatially stable anti aggregation effects on the adsorption layer of particles.

With the continuous progress of ceramic industry, high-performance and high-quality household ceramics, building and sanitary ceramics, fine ceramics, porous ceramics, superplastic ceramics and nano ceramic composites emerge as the times require, among which ceramic additives play an important role.

Alkyl polyglycoside (APG) has a soft effect on the skin, no irritation to the eyes, and a good softening effect on the head. It is widely used in personal care and household detergents, such as shampoo, bath liquid, facial cleanser, hand sanitizer, etc.

The synthesis process of polyether amine includes batch process and continuous process. Huntsman's production process is continuous fixed bed process. Using metal catalyst loaded on the carrier, its production equipment and process are advanced, and the catalyst efficiency is high. Therefore, the product has high conversion rate, less side reactions, low production cost and stable performance, but the equipment investment is huge.

Polyether amine in the use, it is inevitable that there will be improper operation, this is due to our lack of understanding of it, so the direct way to solve this problem is to understand its basic content, then in the emergency situation will be easier, the next small series for you to briefly introduce its emergency treatment I hope you will know how to deal with these situations in the future.

Is it feasible to test the flame retardancy of flame retardant with lighter? Generally, the common convenient fast key test method for flame retardancy of flame retardants is mainly to use lighters. So is it feasible to test the performance of samples with lighter?

Sealant is a kind of sealing material that deforms with the shape of sealing surface and is not easy to flow. It is an adhesive used to fill the configuration gap and play a sealing role. It has the functions of anti leakage, waterproof, anti vibration, sound insulation and heat insulation. It is widely used in construction, transportation, electronic instruments and components sealing. Due to a wide range of sealant, strict operation methods, and poor competition in the market, the sealing effect of sealant is poor. Next, I will analyze the phenomenon and reasons of unqualified sealant.

Alkyl glucoside has low surface tension, no cloud point, adjustable HLB value, strong humid power, strong detergency, rich foam, fine compatibility, non-toxic, harmless, no irritation to skin, rapid and complete biodegradation, and can be combined with any type of surfactant, synergistic effect is obvious. It has strong broad-spectrum antibacterial activity, thickening effect is obvious, easy to dilute, no gel phenomenon, easy to use. Moreover, it is resistant to strong alkali, strong acid, hard water and salt.

Environmental factors have obvious influence on the curing properties of silicone structural adhesive. The first is the influence of temperature. The higher the temperature, the faster the curing reaction. The phenomenon is that the surface drying and debonding are relatively fast. If the temperature is very low, such as below 5 ℃, the curing of sealant will be very slow.

Alkyl polyglycosides can be used in many industries and fields, such as washing industry, cosmetic industry, food processing industry, textile printing and dyeing, pesticide and pharmaceutical industry. As raw materials for non-ionic neutral detergent, alkyl polyglycosides have broad application prospects and can be used as high-grade laundry detergent. In addition, alkyl glycosides have broad-spectrum antibacterial activity against gram negative bacteria, gram positive bacteria and fungi. Therefore, it has more advantages as tableware cleaner, shampoo, skin cleaner and toilet cleaner. Alkyl glycosides can also be used as emulsifier, wetting agent, foaming agent, thickener, dispersant and dustproof agent. In recent years, it has achieved good application effect in pesticide emulsifier.

The high surface activity of surfactants is due to the small van der Waals attraction between the molecules. The tension required for the surfactant molecules to move from the aqueous solution to the surface of the solution is small, resulting in a large number of surfactant molecules gathering on the surface of the solution, forming a strong surface adsorption, and this kind of complex not only has a small affinity for water.

The application of surfactants in ceramic industry involves the theories of material science, colloidal chemistry and surface chemistry. Therefore, it is necessary to study the effect of surfactants on ceramic matrix materials, the sintering and eutectic properties of ceramic matrix materials, and the influence of residual components on product properties.

Over the years, we have been committed to the application of melamine in many aspects and detailed in-depth research. DSM is undoubtedly the global leader in melamine technology.

Consider the characteristics of surfactants. The critical micelle concentration (CMC), which is the low concentration of surfactant micelles in solution, is related to the appropriate dosage of surfactant. There is cloud point phenomenon in polyoxyethylene nonionic surfactant, that is, when the temperature is low, the oxygen atom of polyoxyethylene ether of nonionic surfactant is connected with water molecule by hydrogen bond, so it is easy to dissolve in water and become a clear solution.

In the remediation of contaminated soil, microbial remediation technology has the advantages of non-destructive, economic and safety compared with physical and chemical remediation. It has become one of the promising remediation technologies for polluted environment.  

The surface tension of the degreasing solution containing surfactant is very low and the interfacial energy is small, so when the air is mixed into the solution, the surfactant molecules are adsorbed on the gas-liquid interface in a certain order, so that the formed bubbles have a certain viscosity and tend to be stable. A large number of bubbles only form thin bubbles separated by thin liquid film and form bubbles. Oil pollution plays an important role in degreasing. However, if the bubble is too much, the cleaning machine will emerge. Not only will it pollute the site, but also cause the loss of degreasing fluid, the liquid level will decrease, and the liquid level will decrease and the foam will be too much. Therefore, foam content must be controlled.

Halogen free environmental flame retardant is widely used in high-grade plastic PP PE EVA AB long rubber, wire and cable materials, TV cabinet circuit board, various electrical plastic parts, mining conveyor belt, air duct, plastic mesh belt, plastic damper, plastic pipe, plastic anchor rod, plastic belt roller and other plastic products.

Flame retardant PET is used as flame retardant fiber and fabric. There are usually two methods: one is to use hexabromocyclododecane for flame retardant post-treatment of PET fabric. This kind of fabric can be used as curtain, curtain, wallcovering and other interior decoration cloth. Due to the finishing method, the flame retardant is easy to seep out, and the handle and flame retardant durability of the fabric will be inferior.

Decoration should consider the main fire parts are ceiling, wall, floor, fixed furniture, etc. When many owners install the ceiling, they will choose the wooden keel as the bracket. In order to ensure the safety of the home, they must choose the flame retardant wood treated by flame retardant to do the keel bracket, so as to become the ceiling with fire resistance.
