How to clean carbide? Ultrasonic cleaning machine fast cleaning

Cemented carbide is a kind of high productivity tool material, is a high melting point, high hardness metal carbide powder mixed with binder with powder metallurgy method pressed into a variety of desired shape workpiece, before the carbide coating, or welding must be cleaned from the above attachment, otherwise it will not be coated, before welding if you can not remove the wire cutting residual micro particles will seriously affect the quality of welding, the traditional The traditional cleaning is mainly with acidic liquid direct immersion, such treatment has a certain degree of corrosion on the knife; but the disadvantage is that it can only clean the oil on the surface of the tool, not very useful for the dirt in the micro-hole after wire cutting; if the use of ultrasonic cleaning will completely solve the problem of residue after wire cutting, but must be combined with a special cleaning agent to achieve better results.

The principle of ultrasonic cleaning carbide.

According to the characteristics of carbide surface dirt distribution, and the dirt inside the hole that requires ultrasonic waves have sufficient sufficient penetration, can quickly enter the small hole for cleaning, and be ultrasonic bombardment down from the inner wall of the dirt must flow out of the small hole in real time, so as to avoid repeated pollution of dirt. In the design of carbide ultrasonic cleaning machine frequency, ultrasonic cleaning machine through many experiments, can ensure that the same liquid environment, the design of the ultrasonic frequency to meet this requirement. Because the higher the frequency of ultrasonic waves, the more the number of cavitation bubbles, the greater the density of bombardment, however, with the growth of frequency, the weaker the bombardment force of tiny cavitation bubbles on the carbide, the cavitation strength becomes smaller, so the strength of cleaning is smaller, so you must choose the correct ultrasonic frequency, both to ensure the size and number of cavitation bubbles, but also to meet the strength of cavitation, so that the ultrasonic tank liquid can be filled with both into the small hole Inside, but also can breed sufficient energy to achieve good cleaning effect.

The advantages of ultrasonic cleaning carbide.

1. Carbide cleaning must be able to directly enter the deep hole, the carbide exterior and inner hole can be deeply cleaned, and the technical force is greatly improved.

2. Carbide cleaning must be set ultrasonic density uniformity, ultrasonic effect is better.

3. Auxiliary heating function, the dissolving power of the dirt multiplied.

4. carbide cleaning liquid in the case of high temperature, the use of drying when removed, so that carbide dry.

Cleaning steps and methods.

1. Carbide ultrasonic cleaning machine can be sucked out the air inside the deep hole and the parts, and the cleaning liquid can easily enter the deep hole, and the cleaning ability is greatly improved.

2, carbide ultrasonic cleaning machine in the cleaning fluid after the gas is taken off, the ultrasonic effect is better.

3、The cleaning fluid can be heated above the ignition point, and the dissolving power of the dirt is multiplied.

4、Use the high temperature liquid in the cleaning to provide equal heat to the cleaning parts after drying.

5, in the vacuum solution boiling point down evaporation speed up, because of the rapid formation of high vacuum, covered in the object of the solvent evaporated in one fell swoop.


Due to the characteristics of dirt within the small pores of carbide, there are certain requirements for the cleaning solution used: the cleaning solution should be able to provide a certain degree of alkalinity, with dispersion and suspension, which can prevent the grease taken off from re-absorbing within the product, the alkalinity used is generally better with Ph9~10, and the cleaning solution needs to have a strong solubility to dirt.

The decontamination ability of the cleaning solution is closely related to the temperature. If the temperature of the cleaning solution is too low, it will reduce the chemical activity of the solution, while the dissolution rate of dirt is too low, which is not conducive to the cleaning of dirt in small holes; as the temperature rises, it will obviously change in the direction of favorable cleaning. However, too high a temperature, certain components of the solution are decomposed by heat and lose their effect. When the cleaning temperature is higher than the cloud point of non-ionic surfactants, the solubility of surfactants in water decreases, precipitation upward, so that it loses the ability to degrease. At the same time, too high a temperature, will make the solvent excessive evaporation, but also affect the rate of dissolution of dirt.
