Product Features
1, both hard and soft - made of high quality materials production, that there is a certain mechanical strength, sio2 content more than 68%, Mohs hardness up to 6-7, but also flexible enough to be reused several times, not broken , the same effect as the spray device, the service life than ordinary glass beads 3 times longer.
2, good uniformity - round rate of greater than or equal to 90%, particle size uniformity, spray everywhere after the sandblasting device to maintain a uniform luminance factor, not easy to leave a watermark.
3, can not be replaced - as a kind of glass bead blasting abrasive material than any other abrasive material has the following advantages: in addition to metal abrasive materials, more than any other medium used for a long time, with a non-alkaline soda-lime glass material with good chemical stability, does not contaminate the processing metal, can accelerate the cleaning, while maintaining the original machining accuracy of object
4, smooth without impurities - the appearance of spherical particles, no impurities; surface is smooth, with a good finish, to meet international and domestic standard level
5, round elastic particles, impact resistance, can be recycled many times, less wear and tear
6, the nozzle wear small, extending nozzle life
7, the surface of a sphere, will not damage the machined surface and precision size
8, after treatment, the surface is smooth, with a special beauty, improve product value
9, suitable for dry, wet sandblasting
10, the metal fine cracks fine glass beads with a wet blasting is easily displayed.
The main purpose
1, sand-blasting, paint, in addition to carbon, removal of machining marks
2, for a variety of mold cleanup, except from the shape of the rubber mold mold cleaning agent wire cutting rust.
3, can remove all types of mechanical tensile stress, increased fatigue life
4, a semiconductor device, molding of the tube prior to cleaning to remove the tin side of thorns
5, medical equipment, textile machinery and all kinds of metal products finishing shot peening process
6, metal tubes, non-ferrous metal precision castings cleaning and deburring residues
7, matt surface treatment of stainless steel products, the workpiece surface scratches weld cleaning and removal process
8, anodizing and electroplating before treatment, in addition to clean the outside can help increase adhesion area.
I currently use with micron sieve size table
I currently use with mm sieve size table, please read carefully:
Larger mesh, the smaller the aperture. In general, the mesh × aperture (micron) is approximately equal to 15 000, the so-called mesh that is one inch (25.4mm) length of the number of holes in the mesh.
Mesh :20 - 3000 mesh. Wire diameter :0.03 - 0 .4 mm
