First, the rust is caused by the iron roller rusting in the touch of water or chemicals, air and other material conditions; talent is generated. And it protects the rotation between the roller and the special parts; often encounters a large change in temperature and humidity Because there is no air conditioning between the production and the special parts of our factory; even if there is air conditioning, it is difficult to control normally. Plus the iron roller is cleaned; because the cleaning liquid is also acidic; (because the new circle is treated by acid in the rubber factory) After the factory; and the roller is usually used directly on the new circle without neutralization; so the new circle is acidic.) Once the humidity is high, the iron roll is formed in large quantities; Long iron roll life is shortened; it also affects the quality of yarn.
Second, the rapid descaling method because the bearing iron roller is easy to rotate; the hand is difficult to grasp firmly; it is difficult to remove the rust with the iron sand leather craft; the power is low. We use the hydraulic roller rounding machine (A812 leather roller rounding machine also Can be the top of the roller; cover two sheets of 0# iron sand. The sand skin is fixed with three points of inner, outer, left and right sides of the adhesive plaster. The direction of the sand is fixed in the opposite direction to the rotation of the drum; Approximately 80 × 10 a total of 6; can be fixed a sand. During operation; the starter motor is the upper press roller lift can be carried out. The method is: use a right hand to grab an iron roller; the other iron roller touches the lower roller and The angle is 45°-65°. The hand can effect two forces; one is positive pressure N; one is tensile force F; the effect of making these two forces is different from the rotation direction of the roller and the iron roller; and the conflicting force effect occurs On the sand skin, you can quickly remove the rust. Usually, each sand skin can be rusted by about 200 sets per hour; the hands are faster; and everyone can operate. This method has high power; low cost; no need to add equipment And personnel; it is worth a try. Third, how to avoid the iron roller rust, the condition between the roller and the special parts is necessary to constant temperature Wet. Second, it is necessary to separate the appearance of the iron roller from the air, water and corrosive products; then it is necessary to apply a thin film on the outer surface of the iron roller to complete the knot. We rely on this principle; Roll coating; the ratio is 1:2; the roller coating method is completed once; and the temperature can be rotated for 24 hours to get on the train. However, it is necessary to remove the rust before the coating of the old iron roller by using the above method; Appearance; after 24 hours of constant temperature, the coating can be applied once by roller coating.
The quality of the iron roll after passing the coating is slightly reduced; this is what we expected. The reason is that the iron roll is coated; the film is formed by the film; it can be antistatic; that is, the accumulation of hair is reduced; It can also add conflicting force to the apron; it can reduce the apron slip and the iron roller to be beaten. This way the sliver is evenly manipulated and drafted; the quality of the yarn is also improved.
Fourth, the conclusion of the bearing iron roller derusting method is simple and high power; just contact the large flat car to complete the end; human and material input is also small. If the sanding iron roller is treated with paint once; not only can extend the life of the iron roller Number; can also improve the quality of production to a certain effect. This is a two-pronged approach.

Flap Disc
Flap disc, commonly known as flat emery cloth wheels, emery discs, flower impellers or elastic grinding discs, are a large variety of coated abrasive conversion products, which press the cut coated abrasive sheets one by one. It is formed by sticking adhesive to the back cover plate along the circumference. The flap disc are called strong elastic grinding discs. They are made of calcined emery cloth, which uses mesh, nylon, plastic, steel paper and other materials as the base. Attached abrasive tools, evenly distributed in a fan shape to ensure the best grinding effect. The particle size is 36#-320#, 60# and 80# are the most common, and the outer diameter is 4"-7" installed on the angle grinder. Angle grinders are mainly installed on hand-held Power Tools to polish and polish welds, burrs, chamfers, surface rust removal, and surface polishing of various metal and non-metal parts.
The flat emery cloth wheel (flap wheel) is formed by sticking multiple emery cloth sheets on the tray in a fan-shaped superimposed arrangement, and the bonding angle between each emery cloth and the tray plane is 10°-30°. The emery cloth arrangement of the utility model can make When the abrasive cloth wheel grinds and polishes the workpiece to be processed, the cutting angle is optimized to ensure that the base material of the abrasive cloth wheel and the grinding are consumed simultaneously, which obviously improves the overall wear resistance and grinding efficiency of the flat abrasive cloth wheel, and prolongs the service life of the abrasive cloth wheel. Grind the surface of metallic and non-metallic materials.
product advantages:
Compared with the resin grinding wheel for fixed abrasives, it has the advantages of polishing and polishing at one time, shortening the operation time, saving the grinding cost, high efficiency, good heat dissipation, high grinding efficiency, reducing operator fatigue, increasing machine life, etc. It has strong elasticity, High tensile and bending strength and good grinding effect. The grinding speed is fast, the effect is good, and the noise during grinding is low. It is suitable for various industries or fields of manufacturing such as major metal parts factories and machinery factories. Good weather resistance, salt spray resistance and heat resistance, suitable for use in different regions.
Scope of application:
It is suitable for polishing of stainless steel, metal, metallurgy, automobile, wood, marble and other industries. It is especially suitable for the processing of stainless steel and can replace the resin-shaped grinding wheel. It has strong elasticity, high tensile and bending strength, good self-sharpening, high grinding rate, and low noise. It is suitable for welding seams in the box. Polishing of the edges.
There are different classifications of louvers according to different angles. The following are two common classifications:
According to the appearance: T27 VS T29
Flap disc generally have two shapes, curved and flat.
The flap disc type is also called the T27 type, and the curved type generally refers to the T29 type.
The flap disc type (T27) has a flat surface. It is mainly used to polish the flat surface and the external edges and corners. The flap disc and the workpiece are angled during work, which can complete the grinding and polishing at one time, reducing the work flow.
The curved surface of the curved louver (T29) has an upward arc, which makes the T29 flap disc have a better cutting ability on the plane. When working, the T29 type grinding wheel forms an angle of 15° to 25° with the grinding surface, which is mainly used to deal with the grinding of contours and edges. When there are higher requirements for speed and cutting ability, T29 flap disc is undoubtedly the best choice.

According to the type of abrasive particles: ceramic alumina VS zirconium corundum VS alumina
According to the type of abrasive selected, the flap disc can be divided into three types: ceramic alumina, zirconium corundum and alumina.
Because ceramic alumina itself has many crystals, it has good self-sharpening, relatively neat edges, good heat dissipation, and long service life. Therefore, ceramic alumina louvers are mainly used for the grinding of stainless steel, aluminum and other hard metals.
Zirconium corundum itself is a polycrystalline crystal, with fast cutting speed, good self-sharpening, and strong resistance to high pressure and high temperature. Therefore, zirconium corundum louver blades have strong cutting ability and long service life.
Alumina: single crystal, the cutting ability begins to decline at the beginning of grinding, and the abrasive grains are not easy to break, so the alumina flap disc is suitable for the processing of common metals.
