Mixing process and filling unit for vacuum stone

Abstract

The invention discloses a mixing process and a filling unit for vacuum stone. The mixing process comprises the following steps: preparation of the filling unit: mixing a fine-particle-size solid granular filler with a liquid filler and allowing a soft liquid filling film to be formed on the surface of the solid granular filler; and mixing: mixing granular aggregates of different particle sizes with the filling unit to prepare a mixture. The invention provides the brand-new mixing process for the vacuum stone; according to the process, the fine-particle-size solid granular filler is mixed withthe liquid filler to prepare the filling unit, and the filling unit is then mixed granular aggregates of different particle sizes; and the process allows the liquid filler to be mixed with only fine-particle-size solid particles, so use amount is small, environment protection is realized, and stirring and processing are facilitated. During shaping of the vacuum stone in the mixing process, the filling unit is used for filling gaps among the filling granular aggregates, and the gaps among the granular aggregates are filled in and compacted, so air is discharged to form the vacuum stone.

Description

technical field [0001] The invention relates to a mixing process used in vacuum stones, and at the same time relates to a filling unit body used in vacuum stones. Background technique [0002] As an important part of building materials, natural stone has been widely used since ancient times because of its diverse colors and easy development. However, with the excessive increase of its mining volume and low mining utilization rate, the mining of natural stone is gradually restricted, especially in European countries, which have banned the mining of natural stone. Moreover, the products in each mining area have unique designs and varieties, which further increases the difficulty in their use. People have been looking for alternatives to it. With the development of the economy, building decoration materials are changing with each passing day. As a new type of decoration material, synthetic stone has great opportunities for development. However, the synthetic stone in the pri...

Problems solved by technology

However, this bonding method is limited by the bonding strength, and it is difficult to improve the strength of synthetic stone.

In addition, in order to be able to bond all the aggregates together, more resin needs to be used, which increases the amount of resin used. The increase in resin usage not only reduces the strength of synthetic stone, but also brings environmental problems
