mineral wool production

Production Process of Sound Absorption of Mineral Cotton Board?

Mineral wool decorative sound-absorbing panels of the production process is relatively complex, there are wet long-net acquisition, wet rotary screen, dry paste and molded plastic mold, semi-dry method, and so on, most of the current manufacturers Using wet process. My company's mineral wool acoustic board automatic production line of the introduction of Japan's advanced production technology, the use of wet long net Chaozuo forming, through the pulp, long net Chao Du, dehydration, cutting, drying, cutting, spraying, finishing And other processes to complete the whole process

Wet process production in two steps, the first mixed processing of various raw materials into the substrate plate, and then decorative processing.

the substrate processing

Adding a certain amount of mineral wool into a container and stirring with water to separate the cotton from the slag ball, and depositing the slag on the bottom, mixing the viscous agent and the waterproofing agent into a slurry according to the mixing ratio, , The slurry by the water, vacuum suction, extrusion into a certain thickness of rough, cutting and drying Serve mineral wool substrate plate.
