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:Model parameters of glass fiber reinforced plastic and glass fiber cloth
The materials for strengthen are Medium, vinyl type and flame retardant, vinyl resin. There are many types of materials like phthalate, benzene, alkali free glass fiber roving, knitted mat etc.: polyester resin
Q:Specific classification and application of glass fiber
The excellent resin infiltration and permeability: Glass, in general, is hard and fragile. The warp and weft density is decided by yarn structure and texture. It is suitable for all kinds of spray gun and fiber conveying system. Due to its super strength, it can be used for producing packaging sheet and sports equipment. Twistless roving need to be soaked into resin paste with high content of pigment. The requirement that chopped?strand should be used to enhance thermoplastic?plastics is suitable for alkali free glass fiber.
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 is glass fibre reinforced plastic? What do Glass fiber reinforced plastic used for?
it is commonly known as glass fiber reinforced plastic: Also reduce plastic pollution of not being degradation. 1. 2: Not only can save energy consumption of metal. Glass fiber reinforced plastic products can be used as an alternative to the metal and plastic. It is an ideal material for glass fiber reinforced plastics, as its scientific name is glass fiber reinforced plastics.
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:Which tensile strength of alkali resistant glass fiber mesh is bigger, the lateral one or longitudinal one?
The horizontal one is big, but longitudinal one is small. (the horizontal one is the width direction of mesh)
Q:How to deal with the folding force of glass fiber plastic coated yarn.
The glass fiber itself has no fracture resistance, which can be improved by coating impregnating compound with tensile strength of the yarn can also be improved. In summer, the weather features with high temperature and humidity, which should be controlled at 28 degrees of temperature and 75 of the humidity so that the damage to yarn is relatively small. You may consider to improve the toughness of the coating material.
