What are raw materials used for produce FRP grating?

Composite Grating

Raw material for FRP grating is the first things that customer concern after they purchase the FRP grating machine, what kinds of raw material should i purchase? how much it will be take? and what is the proportion of each kind of raw material should i use? all of these question is very important to a new producer. Today, let us tell you what are the main raw material it will be used for produce FRP gratings.

Mainly raw material include

Resin (corrosion resistance, hardness)

Type: Ortho/ Iso / Iso food grade/ Vinylester/ Phenolic

Glass fiber yarn (reinforced material, strength)

Type: A-glass C-glass and E-glass

Curing agent
Accelerant
Color paste
Filler

Type: Aluminum hydroxide/ Calcium carbonate/ No filler(pure resin)

Description of each kind of raw material:

– Resin

Unsaturated polyester resin is a thermosetting resin, which can be cured into an insoluble and insoluble polymer network polymer under the action of heat or initiator. But this kind of polymer has very low mechanical strength and cannot meet the requirements of most applications. When reinforced with glass fiber, it can become a composite material, commonly known as “glass reinforced plastic”.

– Glass fiber yarn

Glass fiber is a kind of inorganic non-metallic materials with good performance. It has a wide variety of advantages. The advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass as raw materials through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its monofilament is a few microns to more than 20 microns, which is equivalent to a hair strand. Of 1/20-1/5, each bundle of fiber precursor consists of hundreds or even thousands of monofilaments. Glass fiber is usually used as a reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit boards and other fields of the national economy.

– Curing agent

Curing agent also known as hardener, curing agent or setter, is a type of substance or mixture that enhances or controls the curing reaction. Resin curing is the process of irreversible change of thermosetting resin through chemical reactions such as condensation, ring closure, addition or catalysis. The curing is completed by adding a curing (crosslinking) agent.

– Color paste

Color paste is a semi-product made of pigments or pigments and fillers dispersed in paint. The oily colorant is called oily colorant with pure oil as the adhesive. The resin color paste that uses the resin paint as the adhesive is called the resin color paste. The pigment paste prepared by adding surfactant dispersion with water as the medium is called water-based color paste. As there are many types of paints, there are also many types of color pastes.

– Filler

Aluminum powder&Calcium carbonate.

Aluminum hydroxide, commonly known as aluminum powder, is very similar to stone powder (calcium carbonate), but the structure of aluminum powder is hollow, and the structure of stone powder is solid, so aluminum hydroxide can be better Fusion with a resin base, the FRP grating made has a certain degree of flame retardancy, the ribs are delicate and smooth, and the water absorption rate is low (~0.3%).

Why add calcium carbonate to FRP grating?

Calcium powder is called “filler”, filler is used to improve the performance of composite materials (such as hardness, stiffness and impact strength, etc.), and can reduce the cost of solid additives, it is different from the reinforcement material, fiber yarn is the reinforcement material is not as a filler.

Fuction:

1, reduce the shrinkage of the molding parts, improve the dimensional stability of the products, surface finish, smoothness and flat or no light, etc

2, resin viscosity effective regulator

3, can meet different performance requirements, improve wear resistance, improve electrical conductivity and thermal conductivity, most of the packing can improve the impact strength and compression strength of the material, but can not improve the tensile strength

4, can improve the pigment coloring effect;

5, some fillers have excellent light stability and chemical corrosion resistance

6,It can reduce costs and improve the competitiveness of products in the market.
