Glass fiber (original name: glass fiber or fiberglass) is an inorganic non-metallic material with excellent performance. There are many types of materials. The advantages are good insulation, strong heat resistance, good corrosion resistance, high mechanical strength, but the disadvantage is Brittle, poor wear resistance. Glass fiber is generally used as a reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit boards and other fields of the national economy.
What is glass fiber yarn?
Glass fiber yarn is an inorganic non-metal material with excellent performance. There are many types of glass fiber yarn. The advantages of glass fiber yarn are good insulation, high heat resistance, good corrosion resistance, high mechanical strength, but the disadvantages are brittleness and abrasion resistance. Poor. Glass fiber yarns are made from glass balls or waste glass through high temperature melting, drawing, winding, weaving and other processes. The diameter of the monofilament is several micrometers to twenty meters, which is equivalent to one micrometer. Each strand is 1 / 20-1 / 5, and each bundle of fiber strands is composed of hundreds or even thousands of monofilaments.
What are the characteristics of glass fiber yarn?
1. Good electrical insulation and high temperature resistance.
2. High tensile strength, good heat resistance and corrosion resistance.
3. Non-combustibility and good chemical stability.
What is the main use of glass fiber yarn?
Glass fiber yarn is mainly used as electrical insulation material, industrial filter material, anti-corrosion, moisture-proof, heat insulation, sound insulation, shock absorbing material, and can also be used as reinforcing material. The use of glass fiber yarn is far more extensive than other types of fiber, used to make reinforcement Plastic, glass fiber yarn or reinforced rubber, reinforced gypsum and reinforced cement and other products. Glass fiber yarn is coated with glass fiber with organic materials to improve its flexibility. It is used to make packaging cloth, window screening, wall covering, covering cloth, protective clothing. And insulation, sound insulation materials.
What are the classifications of glass fiber yarn?
Untwisted roving, untwisted roving fabric (Gingham), glass fiber felt, chopped strands and ground fibers, glass fiber fabric, combined glass fiber reinforced material, glass fiber wet felt.
What does glass fiber ribbon yarn usually 60 yarns per 100cm mean?
This is the product specification data, which means that there are 60 yarns in 100 cm.
How to sizing glass fiber yarn?
For glass yarns made of glass fiber, single yarns generally need to be sizing, and filament double strands can be unsized. Glass fiber fabrics are all in small batches. Therefore, dry sizing or split sizing combined machines are mostly used for sizing, while warp type sizing machines are not used for sizing. Sizing with starch slurry, starch as a bunching agent, as long as a small sizing ratio (3%) can be used. If using a warp sizing machine, some PVA or acrylic size can be used.
What are the terms for glass fiber yarn?
The alkali-resistant glass fiber has better acid and electrical resistance and mechanical properties than medium alkali.
”Branch” is a unit that indicates the specifications of glass fiber, and is specifically defined as the length of 1 gram glass fiber, and 360 is 1 gram glass fiber with 360 meters.
