What is the main production process of FRP grating? In order to let everyone have a clearer understanding of glass grating, let's understand the main production process of FRP grating together!
1. Main production mode of FRP grating
There are many materials for making FRP gratings, but it is generally required to have the characteristics of easy molding, easy fracture, and good stability. Wood, plaster, wax, etc., the wood we usually use, is a wooden model made of wood according to drawings or mold drawings.
2. The main model of FRP grating
The main mode repair can produce mold manufacturing. Including putty, molding, size, reinforcement. This process is mainly the basic treatment of the mold surface and the whole, to ensure that the size and shape of the wood are consistent with the drawings.
3. Surface treatment of main molds of FRP grating
The process of spray coating, coating curing, grinding, polishing, and wax peeling. In the previous process, the spray coating of the mold should be mastered during the treatment, and the coating should be cured. After the coating is cured, sandpaper should be used on the surface of the gel coat. From some coarse sandpaper to about a thousand, to fine sandpaper. After grinding the mold with sandpaper, finally began to demold the product. By this time, the main production mode is about to end. The main mold can be used to make the mold. The glass grille is basically finished. This process requires a lot of materials and tools. Wood and woodworking equipment is one. In addition, it also includes (also known as putty), some rough sandpaper, more than 1,000 kinds of fine sandpaper, gel) (general product clothing), mold cleaning agent, sealing agent, polishing paste, mold release wax. Except for gadgets used for grinding, polishing, plastic spray guns, air pumps (or other sources), etc.
4. Production-oriented production: The main mode is to establish a good mold release wax, which can form a production mode. The manufacturing process of the FRP grid production mode is as follows.
1) Spray Perot
After starting the production mode, use good things to ensure the result of the glass fiber drawing mold. And the plane reaches a certain thickness.
2) Molding layer
It solidifies at the initial stage and can begin to pave the road. The stacking process is too fast, with 2-3 layers of fiberglass cloth or fiberglass mat a day. There is a certain mold resin on the layer. This resin has better properties than ordinary resins. The bonding process of factory workers includes adding accelerators and curing agents to the resin, coating the tool with adhesive, spreading glass fiber cloth and coating the adhesive, and using a flat fabric driven by an iron roller to expel air bubbles and make The adhesive is uniform. When a certain thickness is reached, the layer ends.
3) Strengthening of the curing of the mold
The mold can be cured naturally or heated, but generally has a natural curing period. Natural curing period to prevent mold damage during production.
4) Surface treatment of the manufactured mold
Production mold hardening time requirements, from the master mold, the slave mold can be used in manual mode, can also be used for high-pressure gas death. The post-mortem production mode also requires surface treatment of sandpaper, grinding, wire drawing, and demoulding products. The demoulded product can be used in the production of the product. The materials at this stage of the glass grid are mold resin, curing agent, and accelerator; resin; glass fiber surface mat, glass fiber mat, glass fiber cloth; sandpaper, mold cleaning agent, sealing agent, polishing paste, mold release products Tools used.
