Since the sand pipe is carried away by abrasive particles at high speed, the choice of material is very important. Generally speaking, the sand pipe material should have high hardness and high wear resistance, both of which are essential. Usually made of tungsten carbide composite material. Usually, in cemented carbide, WC exists in particle form as the main wear-resistant phase, while Co only acts as a binder. However, the existence of this soft metal binder obviously has a great impact on its wear resistance, so the Co content should generally be limited to less than 6%. The shape, size, type and processing conditions of carbides have a great influence on the wear resistance of the material.
Can the 0.8 water jet sand pipe use #60 sand?
1. A good garnet sand should be almandine garnet, dark redce or dark red, also called brown sugar color by some, this type of garnet has high hardness and good toughness, and has an indirect protective effect on water jet equipment.
2. Good garnet sand must come from deep rock minerals or beach minerals cannot be used, otherwise the hardness will be low and the cutting force will be weak, which will directly affect the cutting. cutting efficiency and quality.
3. Good pomegranate sand should be clean, with less dust and impurities. Good minerals also require good technology, which requires multiple magnetic separations to remove unnecessary impurities.
4. Good garnet sand must have a reasonable and uniform particle size distribution. There should be no excessively large particles that damage the sand pipe or gem nozzle, nor excessively small or ineffective particles, dust, and impurities.és which directly affect the cutting speed.
What should you pay attention to when purchasing waterjet sand?
(1) No clogging
(2) Garnet has a deep color and high iron content; high and hard aluminum content, fast cutting speed, moderate cutting gap, straight and smooth cutting surface;
(3) There are no excessively fine particles and dust that affect the cutting speed.
Garnet sand is ground from garnet. It has the characteristics of high hardness, high temperature resistance, stable chemical properties, uniform particles, high grinding efficiency and no scratches. ; surface sandblasting processing industry for various metals, plastics, wood, etc. ; ultra-precision grinding, casting and precision grinding industry for cathode ray tube glass bulbs, optical glass, silicon wafers, etc. Inthe machinery industry;
< p>Yes. Waterjet sand is garnet sand, usually 60-80 mesh products are used, so 0.8 waterjet sand pipe can use No. 60 sand. Production will differ in due to the actual conditions of cutting material and the matching of sand pipe and pump. If the particle size of pomegranate sand is uneven, it will not only cause sand blockage and affect the cutting efficiency, but may even result in defective products.
