Introduction to the characteristics and production process of glass fiber mat
二、Production process of glass fiber mat
The production process of glassfiber matten can be divided into four processes: glass fiber forming process, binder feeding process, glass fiber bonding process and glass fiber winding process.
1. Glass fiber forming process
Fiberglass creel: placed in an air-conditioned room, humidity controlled at 82-90%, and the ply-twisted rovings are placed on the creel according to the set specifications and quantities.
Chopping unit: Each chopper is equipped with an individually controlled variable frequency motor, which can cut several bundles of ar fiberglass roving into equal lengths of about 50mm.
Scattering: It is controlled independently with the chopper, so that the fibers are randomly and evenly spread on the mesh belt.
2. Binder feeding process
The so-called emulsion fiberglass mat and powder fiberglass mat are distinguished by this process.When producing Powder mat, the spraying equipment sprays the sprayed water. This operation is a necessary step for the better adhesion of the powdered adhesive. The powdered adhesive is applied by the dusting equipment.When producing Emulsion mat, the spray equipment sprays latex diluted with water, and the dusting equipment does not work.
3. Glass fiber bonding process
Use an oven to dry the excess water to bond the glass fiber to the glass fiber.
4. Glass fiber winding process
Cool the fiberglass mat, trim the burrs on both sides and cut it to the desired size, and automatically wind it up.
