FIBERGLASS YARN is made from different glass fiber filaments, which are then gathered and twisted into one individual yarn.

Characteristics :consistent linear density,

Application: Mainly used for weaving various reinforce, insulation, anticorrosion, heat insulation fabric and sleeves etc.

We can supply different shapes and roll weight, such as milk bobbin, 3.5kg big and 1.0g /0/5kg small paper bobbin

Remark: The above data are only the representative products, there are different threads, such as 1/3,2/2,2/3,1/5……etc. Also have C-Glass yarn.

Q: Formula of glass fiber yarn: It is usually known as the short fiber. It is fine silk formed by centrifugal force or high-speed air flow Quartz sand, mirabilite,pure alkali and chopped?strand. After processing,the glass fiber is known as staple glass fibre which can be made into various types of flocculent fiber. The production method is roughly divided into two categories and glass wool is the main raw material for the production of glass fiber. Non-continuous fiber produced by roller and airflow is called continuous glass fiber. One is that the molten glass is directly made into fiber, which is known as long fiber. The other is that the molten glass is made into glass ball with 20mm diameter and then it is made into fibril with 3~80 μm diameter by various method. Infinite length fiber, dolomite and fluorite are made by platinum alloy with the method of mechanical?wiredrawing.

Q: How to produce glass steel?: Material： Glass cloth, resin, curing agent tool: Glass?pane or polyester i thin?film process: According to the specifications for glass?reinforced?plastics, glass plane or polyester i thin film should be prepared and then you should tail glass cloth in accordance with requirements. At first, you should compound resin, and then you should put cloth that already have been tailed on the glass pane and cover it with compounded resin until its thickness meets requirements after removing all bubbles in it. After that, you should continue to cover it with polyester i thin film without bubbles and put a piece of glass on it if you want it more neat. A new product is ready after taking off the glass fiber reinforced plastics and trimming it carefully.

Q: The manufacturing technique and process of glass fiber: In general, woven cloth can be produced into roving, twisted or twistless yarn by simply weaving or piecing together. On the basis of the yarn, quartz sand is used as the main raw material to produce fiber cloth by tank furnace, melting or wire drawing.

Q: Main characteristics of glass?reinforced?plastics grating: long period of installation and use, aging resistance, free maintenance and so on. llightweight, glass fiber content of more than 30% (weight percent), beautiful. Glass?reinforced?plastics grating is based on unsaturated polyester resin (includes isophthalic,ethylene, phenolic aldehyde, bisphenol A) and is made up of glass fiber roving( wind or pultrusion, middle-alkali or non-alkali). It is formed by weave and mould pressing in metal mould or by heating after hand lay-up with impact resistance, steadiness, skid?resistance, anticorrosion, fire?retardant and weather resistance. Moreover, this product with insulation and thermal insulation property is flat in appearance, good in quality and is easy to cut.

Q: How many types of glass fiber and what is escorting yarn?: According to the yarn bundle, it can be divided into roving, fine yarn and textile yarn. According to production types, it can be divided into direct yarn and union yarn. Yarn can be divided into twisted yarn and felting yarn according to the degree of twist. According to the manufacturing products, it is divided into winding yarn and twistless yarn.

Q: How to control the indicators and reduce product defects when producing glass fiber reinforced plastic products.: Resins require low viscosity and are easy to operate manually. (2) pay attention to the overlap of the layer of raw materials, resin and unsaturated polyester. Enhance the materials by resin impregnation with roller or brusher, and then the corrosion resistance mandrel is made in the production made by the composite material. (3) advantages 1) As the advantages of straight fiber with reasonable line laying, as the inner lining, it could prevent wrinkles, so mould cost is high. Although the composite products are usually single shell. Twistless roving is used to priduce tube tank. (4) Disadvantages (1) It belongs to the labour intensive production. The filament winding angle and fiber arrangement density are designed according to the secondary active liquid thermosetting(subject to gel condensation) and two layers of fiber reinforced materials (reinforcing material surface mat.) The roving arranged in the creel, composite material and uniform direction; 2) the glass content can not be too high; 4) resin and reinforced material can be combined freely, mold depreciation is low, carbon fiber, phenolic resin, unsaturated polyester; 5) can be used to strengthen reinforced local enhancement.

Q: How to maintain the GRC exterior wall decoration components?: According to DST, The texture of GRC wall decoration component must be alkali resistant glass fiber for reinforcement with right angle.
