Alumina ceramic abrasion resistant lining molding method

 Alumina ceramic abrasion resistant lining as wear-resistant materials with high performance is widely used in various industries, then how is it formed?  Pingxiang chemshun ceramics co.ltd is professional alumina ceramic abrasion resistant lining manufacturer,chemshun ceramics company is to be a formerunner in the field of wear resistant ceramics .  now we are pleausre to show your the tips of alumina ceramic molding method 

1, Alumina ceramic abrasion resistant lining dry pressing: this technology is limited for simple shapes and the inner wall thickness of more than 1mm, length to diameter ratio of not greater than 4 items. Molding methods uniaxial or bidirectional. Pressing machines has hydraulic, mechanical , semi-automatic or fully automatic molding methods. The maximum pressure of the press 200Mpa. Production of up to 15 to 50 per minute. Since the hydraulic press stroke pressure evenly, so there are differences at the time of filling the powder pressing member of different heights. The size of mechanical presses pressure change due to the number of powder filling, easily lead to shrinkage after sintering dimensions differences affect product quality. Thus the process of dry-pressed powder particles uniformly distributed on the mold filling is very important. Filling volume is accurate or not for the manufacture of ceramic parts dimensional accuracy control of a significant impact. Powder particles greater than 60μm, between 60 ~ 200 mesh will receive the maximum free flow effects, pressure forming to obtain the best results.

 2, alumina ceramic abrasion resistant lining slip casting method: wear-resistant ceramic slip casting is formed using the first method. As a result of the cast, low cost and easy to shape large size, shape complex parts. CASTING key is preparation of a slurry. Usually water flux medium, then add glue and binder solution, fully milled exhaust after, then pour injected into the plaster mold. Since the plaster mold capillary adsorption of water, slurry then curing the mold. Hollow grouting, die wall during adsorption slurry of desired thickness, the need to pour out the excess slurry. To reduce the amount of green body shrinkage, should make full use of high concentration slurry.

What are the characteristics of abrasion-resistant ceramic tiles?

What are the characteristics of abrasion-resistant ceramic tiles?  Abrasion-resistant ceramic tiles are widely used in many projects, in the pit furnace is also built with a wear-resistant ceramic tiles, wear-resistant ceramic tiles not only to fire resistance, high temperature requirements, but also to wear requirements, Introduce the impact of wear-resistant ceramic tile wear-resistant factors which have! Abrasion resistance of  abrasion-resistant ceramic tiles  depends on the composition and structure of wear-resistant ceramic tiles. When the abrasion-resistant ceramic tiles are composed of dense polycrystals composed of single crystals, the wear resistance depends on the hardness of the mineral crystals. High hardness, high wear resistance of the material. When the mineral crystals are non-isotropic, the grain size is small and the wear resistance of the material is high. When the material from the multi-phase composition, the wear resistance of the material ...

What are interlocking wear-resistant ceramic tile liner ?

图片
  The shape of ordinary wear-resistant ceramic tiles is a square sheet structure, and they are arranged in rows and columns. There are linear seams between the rows and columns of wear-resistant ceramic sheets. The linear seams along the direction of fluid flow are A smooth fluid scouring gap is formed.      In addition to the normal wear of the fluid on the surface of the wear-resistant ceramic sheet, the erosion gap becomes a breakthrough door for the fluid to wear the side of the ceramic sheet. Under the long-term erosion of the fluid, the seam will gradually widen and the degree of wear will become more and more serious. , the change of connection affects the service life of the wear-resistant ceramic sheet, which in turn affects the protection effect of the anti-wear parts. After this kind of wear-resistant ceramic sheets are pasted, the adjacent ceramic sheets do not have an interlocking effect with each other. The pasting is not strong during installation...

How to improve the wear resistance of Al2O3 ceramics

图片
Al2O3  wear resistant ceramics  as lining of mill and grinding medium, in the construction of sanitary ceramics and other industries has become more and more widely applied. Use material of Al2O3 content is between 90% ~ 99% commonly, in order to produce high density, good wearability ceramic body, must have a suitable raw material performance, forming method can obtain high green density and must have the appropriate sintering temperature and holding time, only the three elements meet the requirements at the same time, in order to achieve this purpose. Chemshun company has been working hard to develop, research, innovation design is most suitable for customer requirements of high alumina  wear resistant ceramic  products.
