Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. 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 pyrophyllite, quartz sand, limestone, dolomite, borosite, and boronite as raw materials. Made by high temperature melting, wire drawing, winding, weaving and other processes, the diameter of the monofilament is several microns to twenty microns, which is equivalent to 1/20-1/5 of a hair. Bundle fiber precursors are composed of hundreds or even thousands of monofilaments. Glass fibers are usually used as reinforcing materials in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates and other fields of the national economy.
Instructions for use:
Dosage range: 0.6-1.8kg/m3, concrete cracking and seepage resistance is usually 1.0kg/m3
Length selection: users can choose 12mm or 19mm according to design requirements
Customized packaging: usually the net weight of small packages is 1.0kg/bag, and small packages of special specifications can also be customized according to user requirements.
Construction instructions: directly put the fibers into the mixer according to the mixing ratio, and the mixing time can be appropriately extended, so that the fibers can be evenly dispersed in the concrete.
Note: If there are no special requirements, the products should be stacked in a dry and cool place. If not in use, please do not open the package to avoid moisture.
standard:
Appearance quality: In the past glass fiber standards, the appearance quality mostly adopts the method of deducting points for defects, but this is not convenient for delivery inspection and arbitration inspection. It was found that this standard stipulates that "glass fiber chopped strands should be uniform in color, and there should be no stains, sundries, strands, etc. that affect the use." Enterprises should ensure that the appearance quality meets the requirements of the standard.
Features: clustering, low static electricity
1. Good temperature resistance
2. Good interface performance with matrix resin;
3. The resin has very good fluidity and uniform dispersion;
4. It can endow the composite material with good physical and chemical properties;
5. Use coupling agent;
6. The use of proprietary sizing agent makes the chopped fiber and the matrix resin have good compatibility;
7. Good processing performance, excellent clustering and dry fluidity;
8. The composite material has high mechanical strength and good appearance quality
