What Are the Different Types of Parts Degreaser?

Degreaser is a complex mixture of organic and inorganic chemicals based on water matrix. It is a new type of industrial degreaser developed using the principle of "emulsification" and "saponification". It is widely used in metal processing, food, textile, transportation, shipping, construction, electrical, pharmaceutical, chemical and other industrial fields. Although the surface substrates to be cleaned are not the same, the purpose of cleaning is the same, all are to restore the surface of the substrate Cleanliness and maintaining the integrity of the substrate surface.

Degreasing agents are mainly composed of

The composition of the degreaser is based on the type and properties of the fat. The degreaser contains two main components, alkalis.

Degreaser suitable for high pressure spray cleaning and

1.Stubborn heavy oil stains for cleaning machinery equipment and machine tool surfaces

2. Used to clean crude oil scale and sludge on drilling platforms, crude oil pipelines and storage tanks

3. For cleaning various types of coking plants

The amount of foam produced by degreasing agents can usually be used to measure the level of its degreasing ability, but the use of low-foam cleaning agents in modern industrial and civilian washing is increasing. There are two methods for the cleaning agent to meet the requirements of low foam: one is to add a defoaming agent to the cleaning agent; the other is to use a low foaming surfactant, such as a polyether surfactant. However, the defoaming ability of a cleaning agent containing an antifoaming agent tends to decrease with time. Xue Wanbo et al. [2] through a large number of experiments, found that soap base, alkylbenzene sulfonate and pingpingjia compounded in the appropriate proportion can be prepared low foam, fast foam break, good degreasing effect. Polyether nonionic surfactants L64, F68, etc. also have better foam breaking speed than the commonly used foam suppressing combination soap-ABS composite system. In the electroplating industry, the surface of the base metal must be degreased before electroplating. If the degreasing agent used generates excessive foam, it will affect the production process.

Degreasing is a key process before plating and painting of metal parts. The effect of degreasing will directly affect the quality of plating and coating. Traditional high-temperature chemical degreasing, organic solvent degreasing, electrochemical degreasing, and high-temperature lye degreasing are gradually replaced by water-based metal oil stain cleaners due to high costs, large energy consumption, heavy pollution, and poor operating environment.
