Degreasing powder use methods and pay attention to what matters?

Degreasing powder is a complex mixture of organic and inorganic chemicals with water as the matrix. In fact, it is mainly a new industrial degreasing agent developed by using the principle of "emulsification" and "saponification. The operation method of degreasing powder is to add tap water to 800L of the cleaning tank; the water in the cleaning tank is heated to 40 ° C; add water according to the proportion of 5% (I. e., 50kg of degreasing powder is added to 1 ton of water). Add phosphorus-free degreasing powder to dissolve while stirring; After all, tap water can be added to 1000L; Heat to the specified temperature (50~80 ℃) for production. The workpiece to be cleaned can then be placed in a prepared bath for 5 to 15 minutes, which is mainly determined by the severity of the metal material and the oil. Of course, when in use, we should also pay attention to the waste water treatment of degreasing powder tank liquid, which can be treated according to the requirements of the local environmental protection department or neutralized with sulfuric acid solution before discharge. Contains slightly corrosive and chemical odors. Wear acid-resistant gloves and a mask when handling. Therefore, in the cleaning process, everyone should avoid drugs sticking to the skin, mouth and eyes, otherwise immediately rinse with plenty of water, and seek medical treatment in time if there is any discomfort. After use, the degreasing powder should be sealed and placed in a dry, cool and ventilated place. oil removal

Degreasing powder use points?

Degreasing powder use points?

Degreasing powder is a kind of powdered cleaning agent products, similar properties and washing powder, in fact, it is also a kind of environmental protection no toxic industrial cleaning agent products, mainly used in all kinds of metal, plastic products surface cleaning. The following is the use of oil removal powder for everyone? Oil removal powder using a variety of surfactants, detergents, penetrants, builders and other refined, with good wetting, solubilization, degreasing ability. As far as we know, it was also found to be non-flammable, but slightly corrosive. In case of skin contact, rinse immediately with plenty of water for 15 minutes. If accidentally into the eyes please rinse with plenty of water for 15 minutes. At present, degreasing powder is widely used in metal, plastic electroplating, printing and dyeing, spraying industry pretreatment chemicals, but also for a variety of hardware surface degreasing, cleaning and other industries. If according to its nature is divided into chemical degreasing powder and electrolytic degreasing powder, according to the type can be divided into steel degreasing powder and alloy degreasing powder. In fact, its alias is also called degreasing powder. In fact, the effect of the agent is the same as that of it, but it is only liquid. Manufacturers also use a variety of surfactants, detergents, penetrants, builders and other refined, degreasing powder has a good wetting, solubilizing, degreasing ability. Degreasing powder is a low-foaming degreasing degreasing degreasing degreasing degreasing degreasing degreasing from a variety of excellent surfactants, detergents, penetrants, builders, etc.

What are the advantages of using degreasing powder?

What are the advantages of using degreasing powder?

Degreasing powder is a kind of powdered cleaning agent products, similar properties and washing powder, is a kind of environmental protection no toxic industrial cleaning agent products. Below we say what are the advantages of using degreasing powder for everyone? Hope to bring help to more people. Simply put, degreasing powder is an industrial cleaning agent composed of a variety of surfactants, corrosion inhibitors and other cleaning aids. Degreasing powder can easily remove industrial heavy oil pollution such as lubricating oil pollution and cutting oil pollution. Now this degreasing powder is widely used in stainless steel degreasing, hardware, zinc degreasing, aluminum, copper, iron, etc. In fact, degreasing powder is mainly formulated from a variety of surfactants and builders. Modern industrial cleaning generally adopts ultrasonic cleaning or spray cleaning, which can easily remove lubricating grease, carbon agent, mildew, etc. on the surface of various substances. It is safe, simple, economical and effective to use. In general, according to different application fields, degreasing powder in industry has successively introduced steel degreasing powder, alloy, phosphorus-free, electrolysis, high temperature and other products. It is recommended that you also have to be clear about your actual needs when buying. The corrosion inhibitor in degreasing powder can effectively prevent the corrosion of metal by degreasing agent. The surface of the cleaned metal products shall be free of corrosion and discoloration. Ingredients do not contain toxic ingredients, heavy metals, nitrous acid and other ingredients, the formula is environmentally friendly. Especially strong ability, speed

Detailed explanation of pretreatment process of steel coating

Detailed explanation of pretreatment process of steel coating

Iron and steel products are often in contact with the air, due to the oxygen and water in the atmosphere and may have the role of SO2, CO2, H2S, etc., it is prone to corrosion, resulting in reduced performance or even damage of steel products. Therefore, it is necessary to eliminate the adverse factors affecting the quality of the coating in the pre-coating treatment. The quality of the pretreatment of steel coating has a great influence on the quality of the coating, which is mainly reflected in the following: 1. Enhance the adhesion of the coating to the steel surface (binding force). 2. Improve the anti-corrosion performance (anti-rust) of the coating on steel. 3. Improve the leveling and gloss of the coating. 4. Reduce coating blistering, pinholes, sand spots and other appearance defects.

Why is it easy to paint die-cast aluminum spraying?

Why is it easy to paint die-cast aluminum spraying?

Die casting aluminum parts in all walks of life has a wide range of applications, the original surface of aluminum die castings are generally burrs, uneven appearance color, easy oxidation discoloration and other phenomena, so aluminum die casting parts in the assembly before application generally need to go through polishing, cleaning, passivation, painting (or powder) treatment, in order to improve the surface corrosion resistance and appearance decoration effect. The most common surface treatment of die-cast aluminum is painting or powder spraying, but in the production process, there are often problems such as insufficient paint bonding force, paint peeling, foaming and so on. What are the causes of the above-mentioned problems of insufficient bonding force, paint peeling and foaming quality? How to solve it

Analysis of Dust Hanging Problem of Galvanized Sheet Ceramic

Analysis of Dust Hanging Problem of Galvanized Sheet Ceramic

The problem of hanging ash on the surface of galvanized sheet mainly appears in two aspects, the first is the excessive corrosion of the surface of the substrate, and the second is the pollution of the external impurities in the process of the galvanized sheet. Excessive corrosion of galvanized sheet generally appears in the following aspects: Galvanized sheet in degreasing free alkalinity is too high, resulting in excessive corrosion of galvanized sheet surface. The addition of caustic soda to the degreasing agent for galvanized sheet leads to excessive corrosion of the surface of the galvanized sheet during degreasing. Galvanized sheet degreasing temperature is too high, too long caused by excessive corrosion of galvanized sheet. Galvanized sheet in the pretreatment process by acid (such as acid tank, acid gas, acid tank after washing tank, etc.)
