The mold shall be made in strict accordance with the dimensions and specifications of the drawing. From the aspects of installation and production, the mold shall be split, and the countersunk bolt position and welding spot shall be reserved, Baotou GRC The mold of finished components shall consider product demoulding, and shall not be clamped. The drill hole at the countersunk bolt position shall be vertical, and the deformed mold shall not be put into production.
Batch: the same batch consists of components with the same raw materials, the same process and the same specifications. Each batch of 500 pieces, if less than 500 pieces, is also regarded as a batch.
General judgment: GRC If the production quality, appearance quality, dimension deviation and bending ultimate strength meet the corresponding grade requirements of the standard under the condition of passing the type inspection, this batch of members shall be judged as members of the corresponding grade.
Stressing bag: lay a small piece of glass fiber mesh cloth at GRC2~222.5cm, but at least 1cm lower than the installation surface, with a diameter of 3~5cm.
Rolling: extrude GRC and trim evenly, and the edge needs to be flush with the mold boundary and end plate. If the product needs welding, reserve welding spots. Reduce solder joints. Chloride ion content in GRC components. The chloride ion content in the component has a great influence on the corrosion of reinforcement. Excessive chloride ions will damage the passive film on the surface of the reinforcement, causing corrosion of GRC component reinforcement. When controlling GRC materials, it is strictly prohibited to use sea sand. The chloride ion content in the sand should be regularly detected. It is strictly prohibited to use industrial wastewater with excessive chloride ion content to mix mortar.
