Audited Supplier The production process of rock wool insulation board mainly includes the following steps:
Preliminary preparation:
Raw material preparation: The raw materials for rock wool insulation board include high-temperature fused quartz sand, limestone, natural gas, and slag, which need to be fully stored and tested.
Production equipment preparation: Prepare corresponding production equipment and tools, such as mixing machines, forming machines, vulcanization furnaces, repair machines, and coating machines.
Mixing:
Raw material ratio: According to different types of rock wool insulation boards, put the raw materials into the mixer in a certain proportion and mix thoroughly.
Mixing heating: feed the mixed raw materials into the mixing heater, adjust the temperature and humidity, and make them reach the appropriate molding state.
Adding water: During the mixing process, add a certain proportion of water as needed to fully moisten the raw materials.
Forming:
Pressure molding: The mixed raw materials are fed into a molding machine and molded under a certain pressure, while controlling the molding speed and temperature.
Cutting: The formed rock wool board needs to be cut to form products with specified dimensions.
Drying: The formed rock wool insulation board needs to be dried to evaporate moisture, improve strength and toughness.
Sulfurization:
After drying, the rock wool insulation board needs to be sent to the vulcanization furnace for vulcanization to meet the requirements of hardness and density.
The vulcanization temperature and time need to be strictly controlled according to the product type and specifications.
Trimming:
After vulcanization, it is necessary to cut, trim, and polish the rock wool insulation board to meet the specifications and quality requirements.
The surface of the repaired rock wool insulation board is required to be smooth and free of defects such as cracks and burrs.
Coating:
Rock wool insulation board can be surface coated through spraying, veneer and other methods to achieve certain moisture resistance, durability, flame retardancy and other properties.
Coating materials need to be selected from environmentally friendly and high-quality products, with strict control over thickness and coating uniformity.
Packaging:
Package the cut rock wool insulation board for convenient transportation and storage.
The production process of rock wool insulation board is a complex and delicate process, which requires strict control of parameters and quality in each link to ensure that the performance and quality of the final product meet the requirements.
