[Polyester Oxford] is an inorganic non-metallic material with excellent performance. The ingredients are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide and the like. It uses glass balls or waste glass as raw materials through high-temperature melting, drawing, winding, weaving and other processes. After that, various products are formed. The diameter of glass fiber monofilament ranges from a few microns to more than 20 meters, which is equivalent to 1/20-1/5 of a hair strand. Each bundle of fiber strands has hundreds or even upper strands. Composed of thousands of monofilaments, it is usually used as a reinforcing material in composite materials, electrical insulation materials and thermal insulation materials, circuit substrates, etc. Polyester Oxford cloth is widely used in various fields of the national economy.
Everyone knows that the standard [Polyester Oxford] is white, unless it is yellow after it is colored, but sometimes polyester Oxford cloth that cannot be distinguished by color is also yellow. What is going on? It is true that the standard color of polyester oxford fabric is white. During the time of gluing and drying, sometimes due to poor temperature control, the temperature is too high and the polyester oxford fabric is burned out, that is, the "yellow" polyester oxford fabric we see.
The standard of polyester oxford fabric is different, and the temperature of the fabric is different when the raw material is different, so we need to adjust the temperature appropriately according to the different conditions of the polyester oxford fabric, otherwise the temperature in the furnace will be too high, which will cause the polyester oxford fabric to be baked. If it comes out hard and severe, the polyester oxford fabric will be baked yellow, and the temperature will be too low to cause the polyester oxford fabric to be baked too soft and not shaped.
[Polyester Oxford] Another important use is to cooperate with plastics to manufacture various glass fiber composite materials. For example, immersing layers of polyester oxford cloth in hot-melt plastic, pressurizing and forming it becomes the famous "glass reinforced plastic". FRP is even tougher than steel, it will not rust and corrosion, and its weight is only a quarter of the same volume of steel. Therefore, the use of polyester oxford cloth to manufacture the shells of ships, cars, trains and machine parts can not only save a lot of steel, but also reduce the weight of the cars and ships, which greatly increases the effective load. Since it will not rust, many maintenance costs can be avoided.
