What are the ways to remove the black spots on the surface of polyurethane casters?
The purification solvent is to use the oxide added to the industrial castor fluid to be wetly absorbed and dissolved by these droplets, forming new droplets to rise to the surface, and to form scum to be removed after cooling. The flux used for purification of industrial casters is composed of salts with low melting point, low density, small surface tension, high activity, and strong adsorption capacity for industrial polyurethane caster slag. Non-metallic inclusions and dissolved hydrogen are removed, followed by continuous elimination, so that fine nitrogen bubbles are evenly distributed in the treated purification liquid for purification.
When the polyurethane caster is in a static state, the working object needs to be positioned, and the auxiliary locking component installed for the caster is the brake of the caster. Casters with brakes, that is, castors with brakes. PU Caster Brake Function The caster brake function means that when the caster is at rest, it is necessary to locate the working object, and the auxiliary component (that is, the caster brake) installed in order to lock the caster.
It is worth noting that the brakes of casters generally work in a working environment without slopes. For special requirements, the design of polyurethane caster brakes, please consult the manufacturer. The classification of brake casters for different working environments requires different designs for polyurethane casters. According to the requirements of customers, the caster factory has designed, developed and mass-produced more than 300 kinds of castors with brakes, including directional brake casters, universal side brake casters, and universal double brakes (locking the bracket and wheels at the same time), the direction of rotation Brake casters (universal rotation directional device), etc.
However, in industrial production, the surface processing quality of the inner industrial casters seriously affects the quality of anodic oxidation products. This contradiction is becoming more and more prominent. Sometimes it will become black if it is prevented in the warehouse. This shows that the industrial casters are starting to oxidize a little, and the industrial polyurethane casters are oxidized. After that, the oxide can be wiped off and placed in the sun for a few days to solve the oxidation problem.
Processing industrial polyurethane casters with 3m length of aluminum hard oxidation, can be used for oxidation processing of mechanical parts, textiles, electronics, auto parts, communications, cooking utensils, speaker audio, printing peripheral parts, LED, solar panel bracket industrial casters, etc. Before the oxidation, the effect of the material composition and purity of the aluminum products on the quality of the industrial casters has long been understood by scientific workers.
