Product Description:

Assembled Roving  for Chopping

162 Assembled Roving for Chopping is coated with  special silane-based sizing, compatible with UP and VE, delivering relatively  high resin absorbability and excellent choppability, while its final  composite products deliver superior water resistance and excellent chemical  corrosion resistance. It is typically used to manufacture FRP pipes.

Package:


Eachroll of AR-glass fiber spray roving weight 18kg. It is wrapped by a shrinkingpolythene film, then to be packed in one carton. 48 cartons or 64 cartons areto be packed in one pallet. 20 pallets (on two levels) are to be loaded in a 20feet container, giving a total net weight of approximately 20 tons.

Other packing methods are available, according tocustomers' requirements.



Storage:


ARfiberglass spray up roving should be stored dry in their original package, thebest conditions being at a temperature of between 15 and 35, and at a relativehumidity of between 35 and 65%. If the product is stored at low temperature(below 15), it is advisable to condition in the workshop for 24 hours beforeuse to prevent condensation.

Q:What parts must used fiber reinforced concrete?
Is mainly used for the tensile and bending resistance parts.
Q:What kind of knife can used to cut glass wool cloth?
You just need to cut off the big square. At first, you need to cut off the big square along border line and center line. Then you should cut off the two overlapping rectangles along the diagonal. At this moment, there are four right triangle which just can be put into a hollow square with its area just is equal to the small square, then you should put the small square into the hollow aquare.
Q:Medium alkali glass fiber cloth
It is mainly used for large and medium sized non-metal container, equipment, pipe and shell.
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.
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:Tetramethoxyl silane coupling agent can be used to be coupling reagent?
Q:What is glass fiber?
It has the advantages of good insulation and corrosion resistance. The diameter of monofilament is from several microns to twenty micron. It uses glass ball or waste glass as raw material and is produced by high temperature melting. Glass fibre is usually used as reinforced composite materials, but its drawback is crisp. It features with poor abrasion resistance, good heat resistance and is used as electrical insulating materials and heat/thermal insulation materials. Its diameter is equal to that of a hair. Each bundle fiber raw silk is formed by hundreds or even thousands of monofilament with high mechanical strength. Glass fiber is a kind of inorganic nonmetal material with excellent performance.
Q:waht about Plastic tray?
Corrosion can not happen. Glass steel bridge use alkali glass fiber roving and its fabric as reinforcement material, welding or screwing connection, with the glass steel life for more than 50 years. Using unsaturated resin as matrix material, plastic colorant, glass steel bridge uses vinyl chloride (UPVC) resin as the main raw material. In fact, the material made for cable tray have something to do with the actual project. Glass steel belongs to high-quality composite materials, plus a proportion of the stabilizer, oil and other corrosive media, then it has antiseptic function and special filler. generally, plastic steel has 15-30years life. It is not very good for acid and salt, and it is not very ideal material for extrusion molding, corrosion protection and so on. Plastic tray has a price advantage, but the strength is not so good . After adding other mineral filler, long life, and then cured by heating, extruding into various sections of the hollow section processing, steel is steel profiles and the main chemical composition is PVC.
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: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.
