Analysis of common problems in plastic milling

In recent years, plastic milling has gradually become a new material processing method, which can use waste plastics, environmental protection and energy saving, and also has the advantages of high efficiency, low cost and easy operation. However, in the process of plastic grinding processing, there will be some common problems, this paper will be combined with the actual production situation, the common problems of plastic grinding processing are analyzed.Problem 1: The crushing effect is not goodIn the plastic milling process, the crusher is one of the most commonly used equipment, and its crushing effect directly affects the subsequent operation progress. The reasons for the poor crushing effect may have the following aspects:1. Crusher tool wear: In the process of use, the tool will go through long-term friction and wear, resulting in a decline in its cutting ability, the need to replace the tool in time.2, the material is too large: if the material is too large, it will lead to an...

What are the requirements for the shape of the plastic powder when it is processed?

What are the requirements for the shape of the plastic powder when it is processed?Shape requirements of plastic powder processing: we have shape requirements for powder particles in different production processes, and we usually say that the tearing powder is attributed to the shape of a strip or pole, and its light transmission and reflection function will lead to uneven color. By spraying on metal or other surfaces, it will lead to uneven and uneven adhesion after high temperature baking.The powder produced by the impact can be described as a stone shape, that is, the longest end is not significantly different from the shortest end. The powder particles can evenly pass through the spray gun mouth, reduce the blockage of the spray gun mouth, the degree of atomization is high, and the spray appearance is uniform, but the coarse powder particles will affect the uniformity of the spray appearance, affect the reflection and light transmission function, and then affect the appearance and ...

Influencing factors and improving methods of flow performance of plastic powder coatings

Influencing factors and improving methods of flow performance of plastic powder coatings1, plastic powder coating fluidity and detectionThe fluidity of powder refers to the degree of the powder coating being fluidized by air in the fluidized bed, which is an important basis for evaluating the construction performance of powder coating. The fluidity of powder coatings can usually be measured by the Angle of repose or the fluidity coefficient. Repose Angle is a direct detection method of powder fluidity, the smaller the repose Angle, the better the fluidity. At present, there are two common detection methods for liquidity:1.1 Standard funnel method(Hall current meter)The method is mainly used to detect the fluidity of metal powder, measuring the time required for 50g metal powder to flow through the standard size funnel hole, the unit is s/50g, the longer the time, the worse the fluidity, and the other way around, the better the fluidity.1.2 Natural accumulation Angle(rest Angle, powder...

Home improvement building materials market warming, plastic powder coating prospects?

Home improvement building materials market warming, plastic powder coating prospects?With the recovery of the building materials industry market, many investors will focus on the paint market, have asked: open paint stores can also make money? I heard that the powder coating market is hot, what is the prospect?As investors said, powder coatings as a new category of coatings industry, recently, is indeed highly sought after. Powder coating is a new type of solvent-free 99.9% solid powder coating, and the general coating is completely different form, it is in the state of fine powder. Because it does not use solvents, it is called powder coating. The main characteristics of powder coating are: harmless, high efficiency, saving resources and environmental protection characteristics.As we all know, green environmental protection is the general tone of global development, and the concept of green development is also reflected in various fields and links of domestic economic and social devel...
