Aluminum silicate needle-punched blanket is an efficient and durable insulation material, which is widely used in industry, construction and transportation fields. The production process mainly includes raw material preparation, batching, melting, casting, needling and post-treatment.
Raw material preparation is the first step in the production of aluminum silicate needle-punched blanket, and raw materials such as aluminum silicate fiber, binder, and alumina powder need to be prepared. Aluminum silicate fiber is the main component of aluminum silicate needle-punched blanket, which has the advantages of high temperature resistance, low thermal conductivity, non-toxic and odorless. The role of binders is to bond aluminum silicate fibers into shapes, and commonly used binders include phenolic resins, polyacrylates, etc. Alumina powder can improve the strength and fire resistance of aluminum silicate needle-punched blankets.
The ingredients are to mix the raw materials according to a certain proportion, and add an appropriate amount of water to stir evenly to form a slurry. In the process of batching, the proportion of raw materials and mixing time should be strictly controlled to ensure the uniformity and stability of the slurry.
Melting is to melt aluminum silicate fiber into liquid at high temperature, and the temperature and time should be controlled during the melting process to ensure the quality and stability of aluminum silicate fiber.
Casting is to process the molten aluminum silicate fiber into sheets through a casting machine, and the temperature and speed should be controlled during the casting process to ensure the thickness and uniformity of the aluminum silicate fiber sheets.
Acupuncture is a critical step in the production of aluminium silicate needle-punched blankets, in which the aluminium silicate fiber sheets are punctured by a needle loom to loosen the fiber bundles into individual fibers, while the fibers are blown apart and positioned with hot air. During the acupuncture process, the density and depth of acupuncture, as well as the temperature and speed of the hot air, should be controlled to ensure the density and thickness of the aluminum silicate needle punch blanket.
Post-processing includes steps such as drying, cutting, and packaging. Drying is to dry the acupuncture aluminum silicate blanket to remove the moisture in it. Cutting is to cut the aluminum silicate blanket according to the required size and shape. The packaging is to pack the cut aluminum silicate blanket to protect it from damage and contamination before use.
In the production process of aluminum silicate needle-punched blanket, it is necessary to strictly control the process parameters and the quality of raw materials to ensure the quality and stability of the product. At the same time, enterprises should strengthen the maintenance and update of production equipment to improve production efficiency and product quality. In addition, enterprises should also strengthen the construction and improvement of the quality management system to ensure that the quality and safety performance of products meet the relevant standards and requirements.
In short, as an efficient and durable insulation material, the production process of aluminum silicate needle-punched blanket needs to go through multiple processes and strict quality control to ensure the quality and stability of the product. Enterprises should strengthen the maintenance and update of production equipment, strengthen the construction and improvement of quality management system, improve production efficiency and product quality, and provide consumers with better products and services.
