The main chain of silicon defoamer in the agricultural production system is very flexible, and its intermolecular force is much weaker than that of hydrocarbons. Therefore, its viscosity is lower than that of hydrocarbons with the same molecular weight, its surface tension is weak, its surface energy is small, and its film forming ability is strong. This low surface tension and low surface energy are the main reasons for its various applications: hydrophobic, defoaming, foam stability, anti sticking, lubrication, polishing and other good performances. The silicon defoamer products of agricultural production system all have good electrical insulation performance, and its dielectric loss, voltage resistance, arc resistance, corona resistance, volume resistance coefficient and surface resistance coefficient are among the best in insulating materials

What is the difference between water-based defoamer and oil-based defoamer? The engineers of Beijing Zhubao New Technology Co., Ltd. and you talk about the connection and difference between the two. Beijing Zhubao New Technology Co., Ltd., which rose rapidly in East China with superior technology, is a comprehensive company integrating scientific research, production and sales. It is a professional company specializing in coating resin, coating ink additives, etc. 1、 What is water-based defoamer? What is oily defoamer? The water-based defoamer is water-based after emulsification by emulsifier and other fillers, while the oil-based defoamer is not emulsified, and it is composed of mineral oil or polyether. 2、 Both

The application of defoamer in the preparation of dispersant The PVC production stage is mainly the preparation of dispersant. When HPMC and PVA are used as suspension agents, they must be prepared, and they must be stirred during preparation, so the solution often foams. The overflow of these foams and the loss of dispersant are caused, and the height of the liquid level cannot be observed. The use of defoamer can eliminate the above foams. Since the suspension reaction liquid is an unstable system, whether the selection of defoamer type is reasonable will have a greater impact on the whole reaction process. In addition, the addition method of defoamer should also be carefully considered. Generally, it should be used 2 hours after the reaction begins

In the pulp and paper industry, the chemical defoamer used is hydrocarbon oil. Mineral oils, such as kerosene and paraffin oil, are used to control foam. Later experience shows that vegetable oils, such as castor oil, linseed oil and pine oil, are also effective for defoaming. In short, other active agents such as wax, which can be dispersed or dissolved in oil, are good defoamers. Defoamers also have some disadvantages. Some defoamers, such as amide type defoamers, will produce deposits, which will cause blocking of screen holes and wax deposition in bleaching tower. In addition, due to the dispersibility, there are "fish eye" transparent spots on the paper surface, as well as some defoamers, which are harmful to sizing agents or reinforcers because of their active agents

When defoamer is added to the foam system, it will diffuse to the gas-liquid interface, making it difficult for the surfactant with foam stabilizing effect to recover the membrane elasticity. The movement law of bubbles is the same as that of liquid drops. If bubbles appear, it will make the liquid more likely to overflow, thus bringing some losses to the manufacturing industry. In addition, bubbles also contain a certain amount of air flow. For example, if the paper industry compresses bubbles during production, the pulp produced will be unevenly distributed, which will affect the quality and operation of enterprise production. The sewage defoamer in the service center of Beijing Zhubao Company is evenly dispersed in the use process, and it relies on non-ionic media to dilute the bubbles

There are many kinds of defoamers. The agricultural production system contains siloxane, polyether, silicon and ether graft, amine, imine and amide, which has the characteristics of faster defoaming speed, longer foam suppression time, wider range of applicable media, and even harsh media environment such as high temperature, strong acid and strong base. In order to break the foam, the defoamer should be concentrated on the foam film. In the case of foam breaker, it should be concentrated in an instant, and in the case of foam inhibitor, it should always be kept in this state. Therefore, defoamer is in supersaturated state in foaming liquid, and only insoluble or insoluble defoamer is easy to reach supersaturated state. Insoluble or insoluble, it is easy to gather at the gas-liquid interface, it is easy to

There are many formulations of efficient degreaser. In addition, the selection and compounding of surfactants is the main reason that restricts the formulation performance of high-efficiency degreasing agent. How to innovate in degreasing agent industry? Formula is an important reason. How to conquer recipe technology? Where is the specialty of formula testing? Nowadays, with the increasing development of industry, degreasing agent plays a vital role. The cleaning and decontamination effects of degreasers are several factors required by enterprises for products. The unique, environmentally friendly, efficient, effective, cost-effective and environmentally friendly detergent formula restricts the development of the enterprise. In other words, whoever attaches importance to the innovation of cleaning agents must

In the electroplating industry, there is often a saying that "there are inferior products in electroplating production, and half of them are not clean after degreasing". Numerous facts have confirmed that this statement is more or less reasonable. Long term production practice has proved that if there is oil stain and other agricultural production system substances on the metal surface, although sometimes the coating can also be deposited, the flatness, adhesion, corrosion resistance, etc. of the electrodeposited coating are always affected by the "interlayer" of oil stain, even the deposition is discontinuous and loose, even the coating peels off, resulting in loss of practical use value. Therefore, degreasing before plating becomes an important process operation. The composition of electroplating degreaser depends on the type of grease and
