As the advantages of permeable bricks gain wider recognition, their applications are expanding accordingly, making price a significant concern for users. With a variety of products on the market, prices vary greatly. What are the main factors influencing price fluctuations?
1. The impact of raw materials on the price of permeable bricks. Controlling the raw material content within a certain percentage ensures proper molding and increased strength. If it exceeds the range, it will cause difficulties in firing, leading to phenomena such as dampness and disintegration, thus lowering the price.
During the drying process, if the shrinkage of the green body exceeds the expected elastic coefficient, it will result in network cracks, leading to a decrease in quality and a lower price.
3. Firing Methods. For instance, the products from tunnel kilns and pusher kilns differ in terms of firing time and fuel consumption. Tunnel kilns have longer firing times and higher fuel costs, whereas pusher kilns have shorter firing times and lower per-square-meter fuel costs, yet the quality differences are quite apparent.
4. Quality: Smooth surface, no hidden marks, and no cracks on the sides, these conditions often indicate large size variations, softness, or brittleness in bricks. Then, place some water on the permeable brick surface and observe the absorption rate; rapid absorption suggests the brick is soft or has low density; slow absorption can lead to frost crystals and brittleness. Check the intergranular bond within the brick; only bricks with good bonding can achieve the required strength.
5. Permeable Paver Manufacturers' Brands. The more renowned a permeable paver manufacturer is, the higher the price will be, which includes a portion of advertising costs. Therefore, when purchasing bricks from small manufacturers, users should pay more attention to quality and price, which are directly proportional.
When purchasing products, users should conduct a comprehensive comparison of permeable bricks, with quality being a primary concern. After that, consider the price factor in making a well-suited choice.
