   是一家专业出产研制的 生态陶 Guangzhou Wanxin Cement Product Factory is a professional manufacturer of ecological ceramics. 的企业。 Enterprise of porcelain permeable bricks .

The following Wanxin introduces the issues that should be paid attention to during the production of permeable bricks :

1. Crushing: Crushing is the use of jaw crushers to crush waste tiles into granules with a certain proportion of particles. The thickness of the particles and the proportion of the particles affect the strength of the semi-product, the firing temperature, the water permeability of the product, the appearance, and the product size. The coarser the particles, the better the water permeability, but the strength of the green body decreases, the firing temperature increases, the surface effect is rough, and the scale becomes larger. Changing the size of the pellets and the proportion of the particles, adjusting the firing temperature, and changing the forming pressure are important goals for adjusting the permeable bricks —the important way of permeable function.

2. Mixing and mixing: The mixing and mixing process must participate in a certain amount of binder (usually bentonite, lignin, etc.) and flux (usually feldspar powder, talc, etc.). The purpose of participating in the binder is to add a combination of granules. Function to enhance the strength of the green body. If it is not added, it will not be able to be molded, maybe the strength will not be good, the semi-finished product will have a large loss, and the product brick will have many cracks.

3. Forming: If the forming press uses an active press, a secondary cloth system is required. The permeable brick is generally composed of a fabric and a base material. , Oscillation brick press, using these presses can be crafted cloth molding. For this product, in order to reduce equipment investment, reduce equipment repair costs, and use cheap labor, using conflict brick presses or vibration brick presses can satisfy process requirements.

4. Firing: Generally, a tunnel kiln is used. The thickness of the permeable brick is about 60mm, and the firing cycle is about 20 hours. A shed car is used, which is usually about 8 layers. The firing temperature is 1200 ° C-1250 ° C. The firing temperature unevenness is determined by the factors such as the water permeability coefficient, flexural strength, appearance color, and scale of the product required by the collected glass ceramic waste and water absorption.
