Good miscibility with cleaning agent, no oil bleaching, no silica spots; Low dosage, high efficiency, alkali resistance; Unique foam inhibition effect, conducive to wastewater discharge; It is non-toxic and odorless, which is conducive to production safety.

Metal alkaline cleaning agent is a metal cleaning agent with a pH value greater than 7, which is suitable for metal processing of steel, iron, copper, aluminum and other metals. Metal alkaline cleaner defoamer defoams in such an environment. Soluble in water, and without affecting the performance of the cleaning agent, rapid defoaming, long time foam inhibition.

The biggest advantage of metal alkaline cleaning agent is that it can have good foam inhibition and stability in a strong alkali environment, fast defoaming speed, long foam inhibition time, soluble in water, and does not affect the appearance of the cleaning agent transparent.

Metal alkaline cleaning agent defoamer is made of a variety of special polyether through the composite process, with high shear resistance and defoaming and foam inhibition function and other good functions, characteristics: adding transparent cleaning agent will not affect the appearance of the cleaning agent, no oil bleaching, no emulsion, no floating, will not produce residual hanging wall.

It is characterized by no impact on the appearance of the cleaning agent, no oil bleaching, no emulsion, no floating, and no residual hanging wall. There is no adverse effect on post-processing. Water-soluble defoamer is evenly dispersed in aqueous solution without affecting the transparency of the solution.

Alkaline cleaning agent is generally compounded with anionic surfactant, the acidity is cationic quaternary ammonium salt, and the non-ionic surfactant is not suitable for strong acid or strong alkali aqueous solution, ester hydrolysis reaction may occur. The general three samples are K12, fast T and sodium dodecylbenzene sulfonate.

Metals are everywhere in our lives. But you know what? The metals we see are all processed metals.

From metal marking, engraving, stamping and etching to grinding and milling, a series of steps are used in our hands. When processing metal in a metal processing plant, metalworking fluids need to be added to assist in the processing. Because metalworking is a liquid specifically for metalworking, it is mainly used to lubricate and cool metalworking products, and the addition of points during processing can also play a role in anti-rust cleaning.

However, when processing in many metal factories, it is found that the metal after adding metalworking fluid produces a lot of foam, and a large amount of foam causes the metal processing work to be unable to continue, and it needs to be continuously washed to clean up the foam. All of these problems are very annoying for the metal processing plant to carry out its work. Therefore, some metal processing plants try to use the metal processing fluid defoamer of Treasure in the Treasure.

Why do metalworking plants blister when they do metalworking?

The water quality is soft, and the water with a degree of softening and alkaline water will increase the foam of the emulsion.

Poor sealing of fluid circulation pumps can also increase the foaming of liquids.

The flow rate of metalworking fluid is too fast, and the bubbles do not have time to spill out, and accumulate more and more, resulting in a large amount of foam.

The volume of the metalworking fluid tank is too small, resulting in insufficient standing time of the metalworking fluid.

The system design is not reasonable, especially the layout of the return pipe and the liquid tank.

There are too many right angles in the sink design, or the nozzle angle of the metalworking fluid is too straight.

Occasional foam problems are often caused by external influences, such as metalworking fluids are polluted by cleaning agents, and infiltrating impurities is the fundamental cause of foaming in metalworking fluids during use, which itself contains many surfactants, and a large number of active agents cause foam foaming.

What are the hazards of metalworking foam?

1. Foam will affect the lubrication, cooling and anti-rust properties of metalworking fluids, as well as metal cleaning and appearance, and seriously affect the quality of metal products.

2. Foam will increase the contact of enterprises, promote oxidation, produce flotation, and make the ingredients mixed unevenly, thus deteriorating and deteriorating the product.

3. The foam will affect the normal operation of the machine, and the oil tank will be filled with foam and overflow, resulting in the decline of the oil level, which will damage the parts and destroy the equipment, and affect the stability of the operation.

4. Foam will affect the anti-rust performance, cleaning performance and extreme pressure performance of the product.

5. Foam will also lead to an increase in production costs.

How can a metalworking plant solve the foam problem during metalworking?

In the centralized cooling system, the pipelines are connected in series at different levels, and the pressure of the pipelines close to the cooling box should be lower.

Ensure that the liquid level of the cutting fluid is not too low, check the liquid level height in time, and add cutting fluid in time.

Control the flow rate of the cutting fluid not too fast.

When designing a sink, care should be taken not to have too many right angles to the sink.

When using cutting fluid, care should be taken that the angle of the cutting fluid nozzle is not too straight.

Add a defoamer or choose a cutting product with good defoaming performance.

Industrial metal cleaning defoamers are chemical agents used to remove grease, dirt, and foam from metal surfaces. Here's how to use it in general:

Determine the type of cleaning agent: according to the cleaning object and the degree of pollution, choose the appropriate industrial gold bench Xiang cleaning defoamer. Different cleaners may have different usage methods and dilution ratios.

Dilute the cleaning agent: Dilute the cleaning agent to the specified concentration according to the instructions for use of the cleaning agent. The dilution ratio of the cleaning agent is usually indicated and can be diluted with water or other solvents.

Immersion cleaning: The metal parts to be cleaned are completely immersed in the cleaning agent to ensure that the surface is in full contact. According to the need, the root jujube can be used to enhance the cleaning effect by stirring or ultrasonic and other auxiliary means.

Friction cleaning: For more stubborn dirt, tools such as brushes, sponges, or soft cloths can be used for friction cleaning. With the aid of a cleaning agent, gently wipe the metal surface to remove dirt.

Cleaning time: Depending on the cleaner's recommendations, the amount of time metal parts are soaked in the cleaner may vary. In general, more stubborn dirt may require a longer soaking time, while light dirt may only need a short soaking.

Rinse: After cleaning, rinse the metal parts with clean water or other appropriate solvents to remove residual cleaning agents and dirt. Make sure to rinse thoroughly to avoid adverse effects of cleaning agent residues on the metal surface.

1.Excessive foam: too much foam will directly affect the effect of the cleaning agent, so that the cleaning liquid can not completely contact with the dirt on the surface of the substrate, which may cause incomplete cleaning and prolonged cleaning time, which is indeed the negative impact of excessive foam.

2.Too little foam, the existence of foam actually has a certain effect of adsorbing dirt, which can adsorb the dirt that is cleaned, so that the dirt will not adhere to the surface of the workpiece for the second time, and too little foam may not achieve this purpose.

1.The generation of foam slows down the industrial cleaning process and consumes energy.

2.The production of foam leads to an increase in the amount of water, and the instability of product production affects the quality of the product

3.The excessive production of foam consumes the service life of the equipment, causing environmental pollution, human health and other hazards.

A: Hello, it's a good thing that the detergent has foam to take away the dirt to a certain extent.

The metal cleaning process will be foamed due to the surfactant and other ingredients of the cleaning agent, which requires the presence of a defoamer.

Since most of the main components of cleaning agents are nonionic surfactants of anionic surfactants, industrial cleaning defoamers require targeted effects on the foaming of anionic surfactants.

In addition, because the flow rate is very high during metal cleaning, the metal cleaning defoamer is required to be shear resistant.

Metal cleaning defoamer is added to the formulation, so it has good compatibility.

Metal cleaning agents are generally alkaline, so metal cleaning defoamers should be alkali resistant.

Finally, the metal cleaning defoamer should be pollution-free, no residue, and do not affect the appearance of the metal.

1. It can eliminate a variety of stubborn types of foam and inhibit the generation of foam during cleaning for a long time; Large bubbles and small bubbles are removed together.

2. It can give full play to the defoaming and antifoaming effect in various cleaning processes; It can meet the process requirements of various cleaning machines, such as ultrasonic cleaning machines, automatic assembly line cleaning machines, large-scale textile industry cleaning machines, etc. It will not cause defects such as oil spots, stains, rust and dirt on the cleaning object. Suitable for all cleaning line defoaming and defoaming needs.

3. Metal cleaning defoamer is developed for metal surface treatment agent and its application. Its advantage is that it can eliminate stubborn foam produced by various surfactants, and can stably eliminate foam in strong acid, strong alkali and high temperature environment.

The metal cleaning defoamer is refined by a variety of special polyethers through a composite process, which has good defoaming and antifoaming and high shear resistance. Easy to rinse without residue, no bleaching, no demulsification, no floating, good heat resistance, stable chemistry, no adverse effects on the later processing of the product.

There are many types of industrial cleaning agents, and their classification methods are relatively simple, mainly according to their chemical composition: inorganic chemical cleaners and organic chemical cleaners; According to the fact that some of the cleaning agents may have different effects on different dirts, or have two or more effects on the same kind of dirt, they should be classified according to their main effects under general circumstances.

1.Aqueous and non-aqueous solvents.

Solvents for dirt are substances that can remove the dirt from the object of cleaning in a dissolved or dispersed form and are not formed by a new substance with a stable chemical composition. It includes both aqueous and non-aqueous solvents.

1) Water: Water is the most important solvent that exists in nature. In industrial cleaning, water is both a solvent for most chemical cleaning agents and a solvent for many dirts. In cleaning, where dirt can be removed with water, non-aqueous solvents and various additives are not used.

2) Non-aqueous solvents: Non-aqueous solvents include hydrocarbons and halogenated hydrocarbons, alcohols, ethers, ketones, esters, phenols, etc. and their mixtures, which are mainly used to dissolve organic dirt, such as oil scale and some organic compound scales.

Among the alkaline cleaning agents, you can choose a surfactant with an alkaline pH value, and you can use Messon Chemical's D550 surfactant, which is currently in use in our factory. The effect is not bad!
