- Q: Who is going to handle the comonent joint of GRC in the exterior wall?
- Both of them should be tested. The installation process will handle it in surface flat, the rest of the process will continue.
- Q: An introduction to glass fiber cloth
- For the occasion requiring high warp or weft strength, the strength of woven roving mainly focus on the warp or weft direction of fabric. Roving roving is composed of parallel raw silk or parallel filaments. According to glass composition, twistless roving can be divided into unidirectional cloth E-GLASS alkali-free glass twistless roving and C-GLASS medium alkali glass twistless roving. Glass fiber woven roving is twistless roving plain fabric and is an important base material for pasting glass?reinforced?plastics. Moreover, it is also unidirectional weft cloth.
- Q: What is glass fiber for?
- It is an excellent inorganic non-metallic materials with good insulation, good corrosion resistance and poor abrasion resistance. It have a great variety and produced by high temperature melting with glass ball or waste glass. It has high mechanical strength and can be used as electrical insulating materials and heat or thermal insulation. Each bundle fibers is formed by hundreds or even thousands of filaments with its diameter is from several microns to over twenty micron.
- Q: The difference between EPS and GRC, advantages and disadvantages, construction technology, key points, the scope of application.
- Fissure is easy to leak water in the cold temperature. Flat connector does not absorb water with a little amount of coating and short production cycle (about 7-12 days). GRC decorative elements is heavy. Due to its shorter installation, it does not require very specialized workers. There is no problem under the temperature of plus or minus 50 degrees Celsius. It has excellent waterproof performance. It has pore and is not easy to chap, but it is easy to deal with and carry with good toughness. If you want to refit it, you need to do some waterproofing work. The connector can absorb water and the material used for producing is belongs to stiffness material with less crack. Finished products features with lightweight, crisp, poor uniformity. High-level job is difficult to process without leakage. Cracking phenomenon is serious and can be cut. Hot bridge is different to control with protective layer features with weathering resistance. Its weight account for 10% of the traditional non light components. Large deformation period is slow. It can be bended moderately. It features with freezing and?thawing resistance and little deformation. It is easy to install and crack so that it needs to be trimmed. It is easy to be linear deformation.
- 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.
- 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: 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: What does glass fiber used for?
- Glass fiber Glass fiber is a kind of inorganic nonmetal material with excellent performance. English name is: Fiber glass. It is produced by high temperature melting, wire drawing, winding and weaving process with the raw materials of glass balls or waste glass. Glass fiber monofilament diameter ranges from a few microns to twenty micron, the equivalent of a hair 1\20-1\5. Each bundle of fibers are hundreds or even thousands of root root filaments, usually treated as a reinforcing material of complex materials, electrical insulating materials and thermal insulation materials, circuit board, etc. and widely used in various fields of the national economy. Properties of glass fiber: The general concept of glass is hard and brittle objects, but it is not suitable for timber structure as its thread. Strength is greatly increased and it is more flexible, so it can finally become excellent timber structure after shaped by the resin. For glass fiber, with diameter smaller, the intensity increases. As a reinforcing material, glass fiber has the following characteristics. These characteristics make the use of glass fibers more broadly than other species of fibers. Its strength is greatly increased and it is more flexible. With good rigidity, it could absorb more impact energy.
- 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.
