Production method of FRP grille is briefly described

Production of FRP grillage basically divides into two kinds, namely wet contact type and dry pressure molding. If according to the characteristics of production process, there are hand paste molding, lamination molding, RTM method, extrusion, molding, molding around molding. Hand paste molding includes hand paste method, bag pressure method, injection method, wet paste low pressure method and mould-free hand paste.

There are four ways to make FRP grilles in the world:

The main application countries are Norway, Japan, Britain, Denmark and so on.

Jet method: the first countries to use are Sweden, the United States, Norway, etc.

Die molding: the first use of countries such as Germany.

Just RTM (resin transfer molding) : mainly used in Europe, America, Japan.

Still have: the fiber encircles to shape the method to pull to squeeze the method and the hot pressure to fill the method and so on

GFRP grille is widely used in daily life. Due to its characteristics of corrosion resistance, light texture and convenient cutting, it is used to make many containers such as darkway cover plate, washer, trash rack and flow sink. However, it also has great advantages in making household objects, such as ventilation Windows and stairs.

Now, with the development of the skills, the more and more people attach importance to the development of new technology and use of glass fiber reinforced plastic grille with little fanfare, is undergoing a transformation, gradually replacing the metal FRP gratings, in all walks of life to carry out the great effect, also be more manufacturer endured, so far, has been a lot of use in the chemical engineering profession, textile professional, power plants, food processing, etc., so why would FRP gratings are so popular? The first thing we need to know about the manufacturing process is that the GFRP grille is woven with fiberglass interwoven. It is made by casting all the moulds of the resin to make the boards with different standards of rectangular and square Spaces. The combination of skills and technology is the attraction of the GFRP grille.

The installation of FRP is mainly artificial, and it can also be laid by relying on tractors or special equipment. The FRP grilles seen in daily life are divided into two types: those with self-adhesive and those without self-adhesive. The self-adhesive can be laid directly on the flat bottom, and the non-self-adhesive requires stainless steel clasp and steel nail fixation, which requires certain physical and human resources.
