Surfactant refers to a substance that can significantly reduce the surface tension of the target solution. It has fixed hydrophilic and lipophilic groups, which can be aligned on the surface of the solution. The molecular structure of surfactants is amphiphilic: one end is a hydrophilic group, the other end is a hydrophobic group; the hydrophilic group is often a polar group, such as carboxylic acid, sulfonic acid, sulfuric acid, amino or amine groups and their salts , Hydroxyl group, amide grou ...

They make the pores fine and uniform. When the system is in the low viscosity stage, it stabilizes the pore wall/the pores can grow to a thickness suitable for the opening, creating conditions for the final opening. The type of foam is different, and the type of stabilizer used is also; at the same time, its main function is to nucleate and emulsify each component in the formula. The compatibility of the various components in the foam formulation is not good, so a stabilizer with a strong emulsi ...

In addition to the waterproofing of the house, attention should also be paid to the waterproofing of the wall surface. Water on the wall will not only lead to a beautiful appearance, but also corrosion of the wall. The penetrating waterproof coating can cause surface tiles, etc., to fall off and fall off, causing some dangerous problems. Next, the editor will explain the penetrating waterproof coating for everyone.What is a penetrating waterproofing agent?It is a powdery waterproof coating conta ...

In today's agricultural production, pesticide spray adjuvants are very popular. Pesticide spray auxiliaries are divided into two categories, namely active auxiliaries, including surfactants, wetting agents, oil-based, adhesives and penetrants; special-purpose spray auxiliaries, including buffers or acidifiers or pH changes Agents, water quality regulators, anti-drift agents, thickeners, blending agents. There are a few things to pay attention to when choosing pesticide spray additives:Pesticide ...

The role of softener1. Supplement the natural oils lost by natural fibers in scouring and bleaching processes, making the hand feel more ideal.2. Attach to natural fiber or synthetic fiber to improve smoothness and strength, and improve hand feeling.3. Improve the wearability of fabrics through certain characteristics of softeners.In order to achieve the above-mentioned effects, softeners are generally grease-like smoothness and hand-feel substances. Adhering to the fiber surface can reduce the ...

Silicone softener originated in the 1950s, and its development has gone through four stages.The first generation of silicone softener: the mechanical emulsification method is used to emulsify dimethyl silicone oil, but since the silicone oil itself does not contain active groups, it is not fast enough to bind to the fabric and is not washable. The effect of single use is not ideal, so it is rarely used as a softening agent now, but dimethyl silicone oil emulsion is still widely used in other fie ...

OverviewSilane coupling agent is a kind of low molecular organosilicon compound with special structure. Its general formula is RSiX3, where R represents amino, mercapto, vinyl, epoxy, cyano and methyl propionyloxy groups. Groups, these groups and different matrix resins have strong reactivity, X represents a group that can be hydrolyzed, such as halogen, alkoxy, acyloxy and so on. Therefore, the silane coupling agent can not only interact with the hydroxyl in the inorganic substance but also wit ...

It was originally a summer festival to eradicate the plague. Later, the poet Qu Yuan of the Chu State committed suic ...

According to the composition of the defoamer, it can be divided into many types, such as silicone defoamer, polyether defoamer, silicone polyether defoamer, mineral oil defoamer, tributyl phosphate defoamer, silicon Oxyane defoamer, n-butanol defoamer, etc. These are relatively common defoamers, and there are some uncommon ones, so I won't introduce them.If it is divided by industry, there are even more. Each industry has corresponding defoamers, such as water treatment defoamers, paper defoamer ...
