Advantages of hot pressing grouting mold compared to traditional ceramic grouting die

Aug 28, 2018

The plaster mold is a traditional ceramic grouting mold. Due to its low heat resistance, the surface has a large pore size, is easy to block, and has low flexural strength, and is used irregularly for high pressure grouting. To this end, a hot press grouting mold has been specially developed, which has a novel structure and reasonable design. 

 

The hot-pressing grouting mold has a Si3N4-BN ceramic material as a mold main body, and a porous protective layer formed of an aluminum cement durable material is adhered to the outer periphery thereof with an adhesive, and a varnish resin sealing layer is applied on the outer periphery and the bottom surface of the protective layer. It is constructed by being placed in a pressure-resistant container with a jet port. 

 

Compared with the traditional grouting mold, the hot pressing grouting mold has the characteristics of high flexural strength, reaching 13Kg/mm2, and can fully withstand high pressure grouting; at the same time, the heat resistance is good, even if it is heated at 1200 °C, it will not Deterioration, can also be formed under harsh conditions. 

 

The average pore diameter of the hot pressing grouting mold is small, reaching 0.5, even if the slurry particles are fine, it will not block, which is beneficial to shorten the molding time; in addition, it has good wear resistance; easy to demould; long service life Other advantages, do not need to change molds and repair molds frequently, significantly reducing production costs. Therefore, the invention of the hot press grouting mold provides a high quality durable forming mold for high pressure grouting.
