What is the application and outlook of fiberglass in the insulation industry?

1. Foreword

  Glass fiber (referred to as glass fiber) is an important raw material in the insulation material industry. It is mainly used as a substrate in the insulation material, and at the same time, it also plays an enhanced role. Fiberglass usually accounts for 30% to 50%of the total weight of the insulation material, which is one of the major raw materials other than the substrate resin, which plays a pivotal role in the insulation material industry. Jinghong Electronic Technology Co., Ltd.'s main product FR4 sheet, one of the main raw materials is glass fiber. The glass fiber has its unique requirements compared to the glass fiber used in other industries. The reason is that the insulation material must have the insulation function, and all raw materials are not contained in or less. Alkaline glass fiber and its products; according to incomplete statistics, the output and sales volume of various types of insulation materials in 2011 are shown in Table 2, which shows that the amount of glass fiber in the insulation material industry is quite considerable

  In 2011, the output of the main products of the company's main products in the insured material industry, the main products of the company,

  Sales volume and sales income

  The output of insulation material products is based on the result of 50 statistics in the insulation industry. The actual demand should be much larger than this data. There are 800 insulating materials manufacturers in the country. Only about 50 are entered. Output and output value.

2. Application

  Among the six categories of insulation materials, the main types of products such as glass fiber and products are soaked fiber products, layer pressure products, plastic products, and cloud mother products. The application situation is divided into:

a) Immerse fiber products

  The main products of impregnation fiber products are: glass fiber lacquer cloth, paint silk, lacquer cotton cloth, sleeve, non -weft band (or rope), pre -immersed material (or gray cloth), anti -halo belt and upper tape, Except for paint silk, lacquer cotton cloth, and upper tape, the rest are not used in glass fiber, and the rest are used in glass fiber. Such products are mainly glass fiber lacquer cloth. The product method is based on glass fiber or other glass fiber products. Materials, soft insulating materials made by impregnation or coating, and then baked and dry. Products have good mechanical strength and softness and high dielectric performance. Widely used for coils, pads and wiring insulation of motors, electrical appliances, electrical instruments and daily electrical appliances. It is also used to manufacture composite materials.

  The insulation lacquer and lacquer silk with cotton cloth and spinning silk can be used as general motor and electrical insulation. It is characterized by high mechanical strength, good softness, but low heat resistance, poor moisture and mildew. It has gradually been replaced by synthetic fiber and glass fiber materials.

The insulation lacquered cloth with alkali -free glass fiber cloth as the substrate has good physical, mechanical and dielectric properties, and has the characteristics of moisture -proof, mildew, acid and alkali, high temperature resistance. Various synthetic resin paint can be made into different heat -resistant grades for motor and electrical insulation for different heat -resistant grades. Various levels of insulation lacquered cloth varieties and uses are shown in Figure 2

b) Laminate Product

  The category of laminate product is a product that uses the most insulated material for glass fiber.

  The glass fiber laminate products are divided into four small categories such as laminated sheet such as FR4 sheet and 3240 epoxy sheet, laminar pressure pipes, laminate rods, and mold pressure. The glass fiber layer pressure products are gradually developed like other varieties, especially chemical treatment glass fiber. The application of cloth and high -intensity epoxy fiber plate, high -temperature resistant diene ether glass fiber cloth board, polyamide amine glass fiber plate, and self -extinguishing copper foil layer and other varieties have successfully developed my country The variety and specifications of thermometry layer pressure products are relatively complete, which basically meets the needs of my country's motor and electronics industry.

  The laminate sheet of the four small layers is the largest, and the printed circuit is used for the most special layer of the compasses in the copper -covered box layer. Due to its excellent performance, the glass fiber layer pressure plate is widely used in industries such as motors, electrical appliances, electronics, aircraft, airlines, vehicles, motor vehicles and ships.

  The laminate sheet is a hard composite product that is impregnated with heat solid or solidified resin. It is stacked by multi -layer phase, and it is heated and compressed. Layers of pressure can be processed into various insulation and structural parts, which are widely used in motors, transformers, high and low voltage electrical appliances, electrical instruments and electronic equipment.

  The layer pressure plate is a hard composite product that is impregnated with heat solid or solidified resin. It is stacked by multi -layer phase, and it is heated and compressed. Layers of pressure can be processed into various insulation and structural parts, which are widely used in motors, transformers, high and low voltage electrical appliances, electrical instruments and electronic equipment.

  The laminar pressure pipe is based on synthetic resin as a bonding agent, and the sheet material as the reinforcement material. The tubular material made of hot rolls and baked is different. The tube formed by the tube and vacuum casting method. The materials used are divided into laminar pressure pipes, laminar -layer cotton fabrics, and layer -made glass fabrics. The laminar can be processed by car (including car threads), milling, drilling, sawing and other mechanical processing. The pressure pipe is mainly used as an insulation sleeve for electrical equipment and other insulating parts, as well as mechanical parts such as axis, shaft sleeve, and ring. It can also be used as a chemical pipeline and low -temperature equipment, empty equipment, and slot vehicles.

  The layer pressure rod is a rod -shaped material made of upper tape and the upper tape with the core rolls. According to the different materials used, it is a tape stick, a tape stick and a glass cloth stick. Mainly used as an insulated structure parts in electrical equipment.

  The molding parts are pressed into various profiles with various types of molds such as resin and enhanced fiber, such as rings, cylinders, grooves, rings, pads, ripples, corners and other parts. Suitable for insulating components for various special requirements.

  The performance of layers depends on the substrate and adhesive and the molding process. According to its composition, characteristics and heat resistance, layer pressing products can be divided into:

  i. Organic substrate layer pressure products are enhanced by wood pulp insulation paper, cotton fiber paper, cotton cloth, etc., and the long -term use of temperature can reach 120 ° C.

  ii. Inorganic substrate layer pressure — enhanced materials dominated by alkaline glass fiber cloth, alkali -free glass fiber felt, and alkali -free glass fiber. The long -term use of temperature is 130 ° C ~ 180 ° C, and it can even reach higher temperatures, which vary from the bonding resin. It can be seen that the use temperature is much higher than the organic substrate layer press.

There are many types of glass fiber cloth layer, and their properties are different with the substrate resin. Compared with other layer pressure plates, the glass fiber cloth plate has higher mechanical strength and heat resistance. (130 ° C) to C -Class (200 ° C), while the long -term use temperature of the organic substrate layer can only reach 120 ° C.

3. Outlook

  The glass fiber applied to the insulation material should be alkaline less, metal, and ionic. This is the basic requirement; with the development of the motor, electrical and electronics industry, it is necessary to develop insulation materials with special requirements to meet the new machines to meet the new machines to meet the new machines to meet the new machines to meet the new machines to meet the new machine The technical requirements of the type, so it is expected that the glass fiber industry will develop more high -performance glass fiber for the insulation material industry to supply, like:

  a) High -performance ultra -thin glass fiber cloth: Power generation equipment has grown from 300,000 and 600,000 kilowatts to 1 million kilowatts. It has reached 1.3 million kilowatts abroad. The voltage has increased from 20 kV to 28 kV. In the power generation equipment, the main insulation requirement to increase the Yunmu content in Yunmu, which is conducive to the main insulation and electricity. Fiber cloth should also be waxless, so that it is suitable for application technical requirements under high -pressure conditions.

  b) Glass fiber felt: Due to the development of the electronics and motor industry, the demand for the pressure plate of the glass fiber felt layer is increasing, and the glass fiber felt plate is low, and the same is good for each. In addition, the reduction has greatly reduced the discharge rate in power generation equipment and high -voltage motors, and increases the life of power generation equipment and motors.

  c) Featured glass fiber: With the development of downstream industrial technology, higher technical requirements are proposed to insulating materials and glass fiber, such as higher intensity, so that it is necessary to technology to improve the affinity between resin and glass fibers. After the traditional glass fiber often finds the insulation material is pulled, the glass fiber will be completely pulled out on the section, indicating that the surface of the glass fiber is too low with the resin affinity.

  Adopting some technical measures for glass fiber, such as alien or glass fiber, will increase the affinity with the resin. In addition, special treatment of the glass fiber surface is also a way to improve affinity.
