High Quality Yellow FRP grating

High Quality Yellow FRP grating

The FRP grating is made by interlacing glass fiber and molded by resin casting. The glass fiber reinforced plastic grating with many regular rectangular and square spaces has two-dimensional homogenous mechanical characteristics. It can be widely used in the working platforms, equipment platforms, drilling platforms, walkways, etc. of petroleum, chemical electronics, electric power, paper, printing and dyeing, electroplating, marine exploration, sewage treatment, etc. It is an ideal product in corrosive environment, and also suitable for Civil construction facilities.

Precautions in the production process of glass steel

1. The surface of the unsaturated resin is sticky, 2. The curing is too fast and not dry.

The two problems are essentially a problem when the surface is sticky and solidified too quickly. If the gel coat is applied to the tacky surface, the reason is as follows: First, or because of the high temperature season, the content of the crosslinker styrene in the resin is insufficient, and the gel coat resin is not sufficiently crosslinked, resulting in a sticky problem; The sprayed gel coat layer is not isolated from the air, and the oxygen molecules in the air act as a polymerization inhibitor, and the molecular chain of the gel coat resin is not sufficiently crosslinked, resulting in a sticky problem. Solution: One method is to spray the surface with air-drying gel coat; the other method is to cover the surface with a layer of cellophane after spraying the gel coat to isolate it from the air. After curing, the cellophane is peeled off to avoid the surface sticking. The phenomenon.

If the gel coat is not applied with a gel coat, ordinary 191 or 196 resin is used. Curing too fast is caused by too much curing agent or accelerator. It is recommended to reduce the amount of curing agent and accelerator.
