In the formulation, the main functions of surfactants are: one is to improve the emulsifying ability between the components, so that they can be more effectively mixed with each other; the other is to control the system to have proper surface tension during the foaming process to produce a good Bubble network structure, therefore, can also be called foam stabilizer. Polyester and polyether flexible foam have different raw material bases and different properties. Therefore, the selection and dosa ...

Whenever we agitate the liquid or be introduced into the gas, many bubbles will be generated inside the surface of the liquid, and some bubbles generated by the liquid will quickly break and disappear. Some liquids not only do not disappear, but also gather more and form bubbles. Foam is a dispersion system formed by a large number of bubbles dispersed in a liquid. The dispersed phase is gas and the continuous phase is liquid. Among them, the volume fraction of the foaming liquid is very small, ...

Defoamers can be divided into many types, including water-based defoamers and oil-based defoamers, so the question is, what is the difference between water-based defoamers and oil-based defoamers ? How to choose them? Let’s talk to the editor of Haian Petroleum!The price of water-based defoamers is relatively low, and they are widely used in textile printing and dyeing, pulping and papermaking, chemical reactions, petrochemicals, metalworking fluids, biological fermentation, water treatment and ...

Performance characteristicsThis product is a long-lasting anti-foaming polyether-modified silicone defoamer specially developed for use in harsh environments such as high temperature, high pressure, acid and alkali using imported raw materials. This product is made of polyether copolymer with strong hydrophilicity and long-lasting foam suppression and polysiloxane with strong hydrophobicity and rapid foam breaking as the main components. This product is different from general emulsion defoamers. ...

my country's herbicide industry has grown from scratch, from small to large, and has gradually developed, and has now formed a complete industrial system. In more than 60 years, my country's herbicide industry has gone through a long process from quotation to introduction, from imitation to creation. According to statistics, since the implementation of pesticide registration in my country in 1982, nearly 200 herbicide varieties (active ingredients) have been registered by the Ministry of Agricul ...

Antifoaming agents are generally composed of multiple components with different functions, that is, main antifoaming agent, auxiliary antifoaming agent, carrier, emulsifier or spreading agent, stabilizer or compounding agent.(1) Main anti-foaming agent: the main active component, usually insoluble particulate matter, such as hydrophobic silica, fatty amine, paraffin, etc. that have been treated with silicone oil(2) Auxiliary defoamer: It is an active component that plays a regulatory role, impro ...

Pesticide adjuvant is the general term for various adjuvants used in chemical pesticide processing formulations in addition to active ingredients. The adjuvant itself has no biological activity, but has a synergistic effect. It can improve the efficacy, reduce the amount of pesticides, save costs, and reduce the pollution of pesticides to the environment. The synergistic effect of adjuvants on pesticides, especially herbicides, is mainly achieved by increasing the amount of pesticides on the pla ...

Silicone wax is a special process synthetic additive specially developed for sewing thread and embroidery thread. It has better heat shielding effect than ordinary silicone oil, low breakage rate, low hairline, good antistatic properties and other characteristics, and the oiling rate Low, generally equivalent to 1/3 of 201 silicone oil; and can greatly improve the smoothness and softness of the thread, increase the luster of the thread, and also have outstanding antistatic properties.Silicone wa ...

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 ...
