Analysis of Production Principle of Glass Fiber Chopped Strand Mat (one)

In the previous article, the first four parts of the production principle of chopped strand mat were introduced. Today, let's learn about the rest of the content.

Five, the factory production has the following parts:

1. Fiber creel

2. Short cutting process

3. Forming section

4. Adhesive Application System

5. Drying box

6. Cold pressing section

7. Trimming and Rewinding

1. Raw materials
The glass commonly used in FRP products is a calcium-alumina borosilicate with an alkali content of less than one percent. It is often referred to as "E" type glass because it was developed for use in electrical insulation systems.
Glass fibers are produced by transporting molten glass from a melting furnace through a platinum jacket containing a large number of small holes, where it is drawn into glass filaments. Filaments for commercial use are typically between 9 and 15 microns in diameter. Before the filaments are aggregated into fibers, the emulsion is attached. The fibers are very strong - the tensile strength is exceptionally high. They also show good chemical and moisture resistance, have excellent electrical properties, are immune to biological attack, and do not burn, with a melting point of 1500°C - excellent performance in plastic reinforcements.powder mat
Fiberglass can be used in a variety of ways, chopped into short lengths ("chopped strands"); aggregated into loosely bound ropes ("rovings"); woven into various fabrics, continuous by twisting and doubling the yarn yarn strands. In the UK, a widely used fibreglass material is chopped strand mat, which consists of strands of fibreglass chopped to about 50mm, held together in mat form using a polyvinyl acetate or polyester binder. The glass fibre mat can range in weight from 100 gsm to 1200 gsm and is useful for general reinforcement.
