As a new type of building material, the Burning-Free brick is mainly made of industrial waste. Compared with the original red brick, it is more environmentally friendly and has a guarantee of hardness and durability.
As long as the name of the burnt-free brick does not need to be traditionally fired, where does the hardness and durability of the burning-free brick come from? Simply speaking, it is mainly the role of two aspects: PHYSICAL and CHEMICAL .
PHYSICAL：
The physical effect mainly refers to the molding pressure of the brick-free machine in the production process. The molding pressure of the modern brick-free machine mainly comes from the following three types:
- Direct pressure forming.
- Vibration molding.
- Pouring force during vacuum casting.
The auxiliary force also comes from the process of wheel milling, mixing and the like.
Some of the current burning-free brick machines use a variety of molding methods, and some use a single molding method, which is of great significance for the preliminary molding of the burning-free brick.
CHEMICAL：
The chemical action mainly refers to the role played by the binder in the raw material of the unfired brick.
Chemical effects are further divided into DIRECT CHEMISTRY and INDIRECT CHEMISTRY
- Direct chemical action is widely used in the manufacture of unfired bricks. Common cementing materials are: gypsum, cement, etc. They can be used for most raw materials, so they are widely used in the production of bruning-free bricks. .
- Indirect chemistry is used in a small range and is not suitable for all types of raw materials. Its principle of action allows the binder to act as a catalyst, causing chemical changes in the raw materials, which in turn cause adhesion to each other. Suitable for active industrial waste.
At present, due to the government’s increasing control over environmental protection, many areas are also more engaged in the production of burning-free brick, burning-free bricks are gradually replacing the architectural significance of red bricks.
