Main indexes affecting the performance of insulation spraying materials

The main indicators affecting the performance of insulation materials are as follows: 1. Insulation resistance and resistivity resistance are the reciprocal of conductivity, and resistivity is the resistance in unit volume. The smaller the conductivity of the material, the greater its resistance. The relationship between the two is reciprocal. For insulating materials, the resistivity is always expected to be as high as possible. 2. Relative dielectric constant and dielectric loss angle tangent Insulating materials have two uses: electrical network components

What should be paid attention to during thermal spraying process?

What should be paid attention to during thermal spraying process? 1、 Respiratory protection. The spraying operation requires the operator to use respiratory protection devices. Depending on the nature, type and size of the dust gas, determine what kind of respiratory protection device to use. For spraying in a limited or sealed space, a continuous airflow channel respirator is required. 2、 Protective clothing. Any spraying or sand blowing requirements

What are the obvious characteristics of the insulation spraying processing board

Characteristics of insulation spraying processing board: the maximum allowable working temperature in the air is very high, which can continue to work at 220 ℃, and can reach 260 ℃ in a short time. It can maintain high mechanical strength, stiffness and hardness in a high temperature environment, and has excellent chemical corrosion resistance and hydrolysis resistance (at present, no solvent that can dissolve polyphenylene sulfide below 200 ℃ has been found, which is extremely resistant to inorganic acids, alkalis and salts),

Thermal spraying principle

Thermal spraying technology is a coating process in which molten (or heated) materials are sprayed onto the surface. "Raw materials" (paint precursors) are heated by electricity (plasma or arc) or chemical means (combustion flame). Compared with other coating processes (such as electroplating, physical and chemical vapor deposition), thermal spraying can provide thick coating on a large area (about

Thermal spraying application

Plasma spraying systems can be classified by several standards. Plasma jet generation: DC electricity (DC plasma), in which energy is transferred to plasma jet plasma or radio frequency plasma through DC high-power arc, in which energy is transferred from the coil around the plasma jet through induction, and alternating radio frequency current forms the medium through the coil plasma:
