Use and classification of keel

Paint keel features and uses

(1) Absolute fire protection: The paint keel is made of fire-resistant galvanized sheet and is durable.

(2) Reasonable structure: economical placement structure, special connection method, combined loading and unloading. Convenient, saving man-hours and simple construction.

(3) Beautiful appearance: the surface of the keel is made of galvanized steel and treated with baking paint.

(4) Wide range of uses: suitable for shopping malls, office buildings, hotels, restaurants, banks and large public places.

classification

Mingjia keel: plane series, groove series, three-dimensional groove series. Dark frame keel: plane series

The overall surface effect of the paint keel is good, the lines are simple and beautiful. The paint keel is safe, sturdy and beautiful, and is suitable for all kinds of mineral wool ceilings, aluminum square ceilings, calcium silicate boards and other supporting construction. It has the advantages of light weight, high strength, waterproof, fireproof, shockproof, soundproof, sound absorption, etc. It also has the advantages of short construction period and simple construction. It is a new type of ceiling decoration material, which is widely used in shopping malls, hospitals, banks, hotels, factories. , terminal building, etc.

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.
