Q:How to make GRC line?
The basic composition of GRC materials are cement, sand, fiber and water, in addition to polymer, additives used to improve the later performance of the materials. Cement: Usually the cements used in GRC are mainly rapid hardening sulphoaluminate cement and low alkalinity sulphoaluminate cement, Portland cement and white Portland cement. Fiber: The fiber in the GRC material must be alkali resistant glass fiber, which include alkali resistant glass fiber roving, chopped glass fiber yarn, alkali resistant glass fiber mesh cloth. European and American countries require the zirconia content in the glass fiber should not less than 16.5%. The polymer: the polymer usually added is acrylic emulsion, also named acrylate copolymer emulsion. Additive: Usually we selectively added superplasticizer, superplasticizer, retarder, early strength agent, antifreeze, anti rust agent and other additives containing products. When there is the steel reinforcement or steel embedded parts, do not use calcium chloride based additives. Other materials: We can selectively use fire.

Q:Does glass fiber reinforced plastic has expiration date?
High temperature. When you store it, you need to pay attention to moisture proof and dust. Glass fiber roving has no expiration date.
Q:The use of glass fiber cloth
Reinforced material:
Q:What is the meaning of Glass fiber reinforced plastic purification tower ant medium
raw materials and technical requirements of glass fiber reinforced resin purification tower production. Resin used in raw material resin manufacturing tower structure layer could be unsaturated polyester resin, epoxy resin, vinyl resin according to relevant requirements. According to the requirement by the supply and demand parties, both sides can choose other suitable winding resin after consulation. The resin used for corrosion resistant layer of the tower could be vinyl resin and epoxy resin according to relevant requirements. In accordance with the requirements of usage, they may also choose other resins with medium corrosion resistance after consultation. Unsaturated polyester resin should comply with the provisions of GB8237 and other resins shall comply with the corresponding standard. Generally speaking, resin should not contain pigments, dyes, fillers or colorants. Exception in the following circumstances: A) The materials we used does not interfere with the visual inspection of product quality and thixotropic agent does not affect corrosion resistance requirements of products ; b) if both parties agree, pigment, dye or colorant can be added into resin; c) if both parties agree, ultraviolet absorbent or flame retardant can be added into resin.
Q:What is sheaf packing in waste plastic industry?
1, It is sheaf packing, but not the debris or particles packed space bags. 2, White cast is the color of fracture part and it includes blue, white and slant blue. The white cast should be transparent or white.
Q:Can you describe the production process of glass fiber and the production process?
The production process of glass fiber generally includes: Purchase the raw materials, mixed according to the formula, and then transfer to the glass furnace for melting and refining, after operation channel flow to the bushing, the sizing agent after coating by wire drawing machine traction, forming the original cake, and then flow to the rear section reprocessing procedures (usually a short cut, winding, weaving, puffing and twisting) or sell (direct yarn)
Q:What's the difference between g;ass reinforeced plastics and ordinary glass?
There are no difference and there are all glass fiber reinforced plastic!
Q:What are the components of the GRC cement component?
The thermal insulation properties are so good that they can pass through the bricks with its thickness over 570mm, alkali resistant glass fiber chopped yarn,150 tons discharge valve and so on. Bulk cement silo is a cylindrical structure, welded by guardrail and pressure relief valve. The bottom is composed of four supporting legs for sustaining the whole silo. Cement component use lightweight foam concrete thermal insulation board so that they don't need to build external wall foam insulation layer.Cement component is composed of dust catcher and high and low material level meter with 100 tons and 500 tons specifications. The experimental results shows that the house with the use of this product can greatly reduce the heating and cooling power. Bulk cement silo meets industry standards.
Q:What does glass fiber operating tools do ?
wire drawing,drying, winding, fabric and so on.
Q:What is the difference glass fiber roving and fine yarn ? Does the equipment used for production have any difference.
6 microns non-alkali, 9 micron twistless roving (bulk yarn), 80 alkali , 30 twist roving ans 21 medium alkali. It is a glass fiber integrated production enterprises combined management, scientific research and development. The company has advanced production equipment and strong technical force. Main production includes 30 alkali-free glass fiber yarn and 40 fine yarn with annual production of 1500 tons.
