Sealant is one of the commonly used materials in buildings, which can be used for sealing and bonding various joints or holes in building parts such as building exterior enclosure, interior decoration and window structure. Different building joints have different requirements for the performance of sealant. The sealant used in exterior wall, bathroom, toilet, kitchen, balcony, floor heating system floor, insulating glass and other building parts should have high waterproof and moisture resistance.

Surfactant industrial cleaning agent manufacturers found that the current industrial cleaning agent industry is almost the same as the "traditional manufacturers", and they basically follow the old road of traditional industrial cleaning agent manufacturers, and the marketing means are also poor. Industrial detergent manufacturers believe that for industrial detergent manufacturers, it is a good choice to boost social marketing with the help of distributors.

Biosurfactant is a kind of multifunctional and excellent treatment agent, which has the characteristics of biodegradation and low toxicity. It has a wide application prospect in environmental remediation. But up to now, due to the high production cost, it is still unable to compete with the synthetic chemical products on the market, which also affects its wide application. It is necessary to improve the production process of microbial surfactant, increase the yield and reduce the production cost. A kind of

Polyether amine in the use, it is inevitable that there will be improper operation, this is due to our lack of understanding of it, then the direct way to solve this problem is to integrate its basic content, so that it will be easier in case of emergency. Next, we will briefly introduce its emergency handling matters I hope you will know how to deal with these situations in the future.

The halogen-free flame retardant for PP is a kind of nitrogen phosphorus flame retardant. It is a halogen-free and intumescent flame retardant specially developed for polypropylene. It has good compatibility in polypropylene, has little effect on the mechanical properties of plastics, and has excellent processing stability in the processing process. PP special environmental flame retardant is different from halogen-containing flame retardant. In the process of combustion, dense expanded carbon layer is produced to achieve the purpose of heat insulation and air flame retardant, without irritating hydrogen halide gas and black smoke. It is an environmental friendly flame retardant.

Polyether amine technology is mainly through a series of technology to produce the products we need, so what are the characteristics of the products produced? I hope you can deepen the understanding of polyether amine in the following introduction.

In the application of surfactants in cosmetics, anionic surfactants are more and more widely used. They have rich foaming property, good emulsifying ability, moderate cleaning power and special skin affinity, which can meet the requirements of hair cleansers. Cationic surfactants can be used in hair care products, Including hair conditioner and hair styling gel, it is also a very effective antistatic agent to make hair more supple. Zwitterionic surfactant itself has low toxicity, low irritation to skin and eyes, so it is widely used.

With the increasingly prominent environmental problems of chemical surfactants, the application of biosurfactants has attracted more and more attention. In the late 1980s, the development of biosurfactants by bioengineering technology has become a new topic in the field of international bioengineering. In the past 20 years, with the rapid development of modern biotechnology and the application of biosurfactants in oil exploitation, environmental protection, pharmaceutical, food processing and other aspects, people have a strong interest in the use of this technology in the industrial field. The enhancement of global environmental awareness has promoted the trend of biosurfactants replacing chemical surfactants.

Alkyl polyglucoside surfactants can form hydrophobic groups on the surface of the fiber and reverse adsorption outwards, so as to reduce the dynamic and static friction coefficient of the fiber material, so as to obtain a smooth and soft handle. Generally, surfactants and finishes are always used together. Surfactants can effectively reduce the static friction coefficient of fiber materials, while finishes can reduce the dynamic friction coefficient of fiber materials. The effect of soft lubrication can be expressed by the difference between static friction coefficient and dynamic friction coefficient. The smaller the difference is, the stronger the soft lubrication is.

Surfactant molecules have both hydrophilic and lipophilic groups, which is also called amphiphilic. Due to this characteristic of surfactants, they can form micelles in water at appropriate concentration: the hydrophilic head is attracted by water outward, and the lipophilic tail is repelled by water and faces inward. In the process of washing clothes, oil stains are pulled to the interior of micelles by lipophilic groups, and the whole micelles are taken away by water.

Surfactants, also known as interfacial active agents, are organic compounds that greatly reduce the interfacial tension of solutions at low concentrations. The molecules contain hydrophilic polar groups (such as hydroxyl, carboxyl, sulfate, amino and ether bonds) and hydrophobic nonpolar groups (such as various C-H chains). According to their structures, they can be divided into four types: anionic, cationic, nonionic and amphoteric.

Polyether amine technology is often used as a kind of foaming agent after polyether amine is generated. Of course, it is because of the existence of such products that we can achieve a good effect when using products. However, when we use it in styrofoam, what should we pay attention to?

In the washing process of textile processing, some processes should not only consider the washing effect, but also consider the softness and fading of the fabric. Therefore, the development of new surfactants with good washing effect and maintaining the softness and color stability of the fabric has become a hot spot in the research and development of new surfactants.

Surfactant is known as "industrial monosodium glutamate". It is not only widely used in chemical industry and many other traditional industries and technology fields, but also in high-tech fields such as materials, energy and life science.

The production of biosurfactant by fermentation has the advantages of low production cost, variety and simple technology, which is convenient for large-scale industrial production, but the cost of separation and purification of the product is high.

Sealant is a kind of material widely used in our life. It is a kind of similar ointment, which is a kind of adhesive commonly used in family. Its main components are sodium silicate (Na2O · msio2), acetic acid and organic silicone. Once the material is exposed to the air, it will solidify and play a role of adhesion, and the adhesion performance of different types of silicone adhesive is not the same. Deacetylation, dealcoholization and deamination are the main components of silicone adhesive. Because the cured silicone adhesive is translucent, it is also called glass adhesive.

The price of sealant is not the higher the better, there are many kinds of sealant, silicone sealant, polyurethane sealant, polysulfide sealant and so on. And each kind of sealant classification is different, it has different classification standards, can be classified according to the base material, can also be classified according to the purpose, can also be classified according to the performance.

New gemini surfactants and biosurfactants are widely concerned because of their high efficiency and environmental friendliness. The solubilization efficiency of Gemini surfactants and biosurfactants is higher than that of traditional surfactants.

What are the requirements for the application of flame retardants in foam plastics? With the expansion of the application scope of rigid polyurethane foam, the performance of foam plastics has higher requirements, among which flame retardants are the main problem. Rigid polyurethane foam is widely used in refrigerators, refrigerators, refrigerators, refrigerators and other insulation materials. The basic defects of buildings, tanks and pipes are flammable. Now, together with the flame retardant manufacturers, what is the requirement for the application of flame retardants in foam plastics?
