FRP process piping manufacturing process?
A, lined with resin preparation. According to the quality control department according to the work environment, temperature conditions made resin formula system for lining resin matching, batching quantity according to the manufacturing schedule reasonable grasp. When the situation changes, the quality inspection department and the manufacturing department shall adjust the formulation in time, and prepare the resin according to the new formula;B, material preparation. According to the design requirements, the material needed for making the lining is transported to the designated position, and some wide width reinforcement materials are firstly cut and processed to the design width;C, lining production. According to the design requirements of the paving layer step liners, each layer in the process of laying under reasonable tension between the amount of overlap, and combined pressure roller rolling repeatedly from bubble to ensure fiber soaked completely. And requests each enhancement material layer to achieve the design resin content request;D, preliminary self check. According to the design requirements of overlay end of each layer, the operation requirements for quality testing of workers: whether the design meets the lining thickness, whether there is a local poor glue, hanging glue phenomenon, whether there is a white spot, whether there is a bubble, etc., if the occurrence of the above situation timely report and take measures;
Preparation processA, device debugging. First, carefully check the equipment operation and work site is normal, especially to carefully check the resin curing agent for two-component pump is clogging, the ratio between whether to meet the design requirements; to ensure the lining, winding, trimming, stripping and other equipment operation stability and accuracy;B, cleaning mold. Mold surface without pit, dust, debris and other attachments, the mold should be smooth surface, there is a problem in time to repair and maintenance;C and wrapped polyester film. For the convenience of pipeline release, with 1 layers of polyester film in the mold surface film, lap width of 1 ~ 2 cm, the thickness is between 40um. For the film without damage, no fold, both sides are smooth and clean. The quality of the film meets the requirements of GB 13950-1992.
Glass tube wall structure from inside to outside are: glass fiber reinforced plastic lining layer, glass fiber reinforced plastic sub lining layer, glass fiber reinforced plastic winding layer, glass fiber reinforced plastic external protection layer.
The glass fiber reinforced plastic lining layer and the glass fiber reinforced plastic secondary lining layer have the function of corrosion prevention and seepage prevention, and the winding layer takes on the strength and the rigidity function of the pipeline, and the outer protective layer has the function of resisting aging, corrosion prevention and anti Japanese sun.
