Preparation: First remove all the debris in the tower, and draw the horizontal line on the inner wall of the tower according to the top of the porcelain ball and the catalyst layer, as the paving height mark. Carefully inspect the ceramic balls of different particle sizes, and store them according to the particle size marked on the product packaging, and store them separately for paving.
Ceramic balls are generally paved.
When paving the bottom layer of porcelain balls, care should be taken to avoid damage to other systems in the tower. The porcelain ball to be loaded shall be hoisted into the tower and then spread; when the porcelain ball is laid to the top level of the layer, the paving personnel shall not stand or walk directly on the supporting material. Should stand on the board. The number of operators operating in the tower should be as small as possible to avoid the movement of the ceramic sphere. After the next layer of paving is completed, a layer of catalyst or ceramic balls can be placed. The thickness of each layer of ceramic balls should be accurate and uniform. The surface should be scraped with a squeegee or scraper, and the height should match the horizontal line of the paving height mark.
