The process of making ceramic insulation board usually includes the following main steps:
1. Raw material preparation:
Prepare raw materials such as foamed ceramic particles, foaming agents, cementitious materials, etc., to ensure that their quality meets the requirements.
2. Ingredient mixing:
Mix the foam granules, blowing agent and cementitious material in a certain proportion to ensure that the mixture is homogeneous.
3. Mold preparation:
According to the specifications of the foamed ceramic insulation board produced according to the need, the corresponding mold is prepared. The mold can be made by casting, injection molding, etc.,
Ensure the accuracy and surface quality of the mold.
4. Inject the mixture:
Inject the mixed material into the mold, and pay attention to controlling the amount of injection to ensure that the size and density of the insulation board meet the requirements. In the note
During the process, vibration and compaction are also required to remove voids and air bubbles.
5. Foaming:
After the mixture is injected, the mold is placed in a foaming furnace for foaming. The temperature and time inside the foaming furnace need to be based on the specific material and
The process requires control to ensure good foaming.
6. Curing:
The foamed ceramic insulation board needs to be cured to improve
its strength and stability. The curing process can be carried out by natural curing or heat curing, etc., and is selected according to the specific process requirements
Choose.
7. Cutting & Trimming:
The cured ceramic insulation board needs to be cut and trimmed to meet the specified size and shape requirements. Cutting can be carried out using cutting machinery, while trimming requires manual operation to ensure that the surface of the insulation board is smooth.
8. Inspection & Packing:
Carry out quality inspection and inspection on the production of foamed ceramic insulation boards
The content includes size, density, strength and other indicators. Qualified insulation boards need to be packaged to guarantee that they are not damaged during transportation and use.
Through the above-mentioned technological process, foamed ceramic insulation board with excellent thermal insulation performance and fire resistance can be produced, which is widely used in building exterior wall insulation, fire isolation belt and other fields.
