Q:What is the difference between the glass and glass reinforced plastics?
Glass and glass reinforced plastics is totally different two things.Generally speaking, glass reinforced plastics is a kind of plastics with cloth or felt made by glass fiber as reinforced plastics.
Q:What equipment is needed for teating glass fiber twistless roving?
Material tester.
Q:What are the differences between glass fiber and asbestos?
Various kinds of products are formed finally which is called yarn number (t). The content of chrysotile is the most abundant. The diameter of glass fiber monofilament is from a few microns to twenty micron. 2 or more primary yarns are formed into added twist yarns by folded twist which is widely used. Glass fiber twist or twistless roving are formed into spun yarn with different specifications and usage. There mainly are alkali free. Composite line is formed by two or more fold twist. Glass fiber is a kind of inorganic nonmetal material with excellent performance. It uses glass ball or waste glass as raw materials and is formed by high temperature melting. It mainly is used for producing glass fiber products. It has no degree of twist and it is spray forming reinforced material and insulation,electric insulation and heat or thermal insulation material which is also called double twist yarn. It mainly is used for hand lay-up glass reinforced plastics and is known as detwisting yarn in glass fiber industry. The meaning of metric system number. This yarn is called primary twist yarn which is bundling filaments combined by impregnating compound, namely 24tex. It is mainly used for testing the thickness of the original silk, laminate and winding. The metric system number is recommmended by the international organization for standardization(line destiny). 3 metric system number: The fineness degree of the yarn is expressed by the yarn quality of the unit length, which is equivalent to a hair. The smaller the number is, the thicker the yarn is. Monofilament is equal to 20tex. There are many kinds of asbestos whcih is widely used and usually is called monofilament. The former is a fixed length, the latter is a fixed weight.
Q:The difference between the BMC and DMC DMC?
DMC is an ordinary premix molding compound with flame resistance and insulation. As continuously promotion, its social demand increases rapidly in United States. BMC has many different names.It mainly uses the polyester molding compound for production. Such great value and vitality of the new materials like BMC will play an increasingly important role in a wide range of areas. DMC is also known as the BMC. Although the development and application of BMC in China started late, it significantly promoted the industrial materials and technological progress. Because of their similar nature and process consistency, bulk molding compound such as DMC has the feature of leakage resistance and rigidity. especially the tensile strength of BMC which is based on unsaturated polyester. BMC refers to modified premix molding compound based on isophthalate polyester resin. With mass production and free coloring, it is irreplaceable for other raw materials. Bulk premix molding compund. In 1989, the development of everthing is inevitable.
Q:HS code for alkali-free glass fiber yarn
The HS encoding the alkali-free glass fiber roving yarn is 70191200 and chopped yarn, spinning and Chinese HS EU tariff as follows, S and Z. Spun yarn is a spinning twist E-glass fiber. My question is whether it is yarn or spun yarn. If it is yarn, it would be twistless.
Q:Can glass fiber be used for cement components
Glass fiber reinforced cement products uses glass fiber to produce cement component. The glass fiber should be alkali resistant glass fiber twist roving, alkali resistant glass fiber chopped strand and alkali resistant glass fiber mesh cloth which comply with JC/T5,72 or JC/T 841 requirements. The cement should be in accordance with JC7/14 and portland cement should comply with the provisions of GB 175. Portland cement must be mixed with absorable Ca (O H), alkali materials or acrylic acid emulsion with the content of alkali resistant glass fiber is higher than 16%.
Q:Introduction of inorganic glass fiber reinforced plastic air pipe
Inorganic glass fiber reinforced plastic air pipe, according to the properties of the binding materials, can be divides into: Made of binding materials with glass fiber mesh cloth hydraulicity inorganic glass steel duct and made of cementitious materials and glass fiber mesh air hardening modified magnesium oxychloride cement duct with two types of modified magnesium oxychloride cement to the sulfate type. The pH value of the hardened material should be less than 8.8, and there is no alkalinity corrosion of the glass fiber. Inorganic glass steel duct should be used alkali-free, medium alkali or alkali resistant glass fiber mesh cloth, and are consistent with current national standard "glass fiber grid" JC561, "the alkali free glass fiber roving," JC/T281, "in the alkali glass fiber roving" JC/T576 regulations. The quality of magnesium oxychloride cement duct Magnesium Oxide should comply with the national standard "Magnesium Oxide" light burned magnesite products with WB/T1019-2002 regulations. Inorganic glass steel duct can divided into the overall common type (non insulation), integral insulation type (inner and outer surface of inorganic glass steel, middle insulating material) and combination type (by special adhesive, composite plate, flange, reinforcement angle etc) and the combination of insulation, its production parameters should comply with the provisions of the table 1, 2, 3. The longitudinal and transverse lap joint distance between adjacent layers of glass fiber grid cloth should be more than 300mm, and the distance of the same layer lap joint shall not be less than 500mm. Lap length should be greater than 50mm. The wind pipe surface thickness of the slurry flating glass fiber mesh cloth is appropriate. And the surface do not have dense pores and spillage.
Q:What can glass fiber grid do in road engineering?
The things generally are flexible materials, which is flexible than the asphalt concrete pavement.
Q:The use of glass fiber cloth
Reinforced material:
Q:What is rippled glass?
The twistless roving glass fiber and its products and materials with unsaturated polyester resin as main raw materials, is similar to sinusoidal wave form and trapezoidal cross sections.
