No matter what the product before going on the market, must undergo rigorous inspection, so how to look at the shortcomings of SMC glass fiber reinforced plastic water tank? The primary instrument inspection method for X ray inspection, checking the common glass steel products defects such as cracks, delamination, resin concentration, loose, fold, metal dopant etc.. Glass fiber reinforced plastic water tank how to detect?
(1) crack or delamination: the first refers to the cloth layer and the cloth were cracking, negative impression characteristics: crack or delamination of the laminated sheet is flat and ends with sharp or zigzag black lines; cloth around the crack or delamination in the products are straight or slightly wavy black is the center line, or wide, "both ends of the spindle tip crack shape molding impression; the product, product appearance varies, mostly ends have sharp twists and turns black line.
(2) resin aggregation: that is, a certain part of the resin is too much, the negative impression of the film and the characteristics of cracks or similar, but the degree of equality than the crack impression of the impression is small, and the impression is not clear summary.
(3): the product of a loose part of the close down, there are small pores scattered irregularly, or small cracks, small resin industrial agglomeration. The negative impression features, irregular shaped patches of black clouds.
(4): according to the direction of the same fold into circumferential folds (along the circumferential and axial dispersion products (product) fold along the axial direction). The image of the film is characterized by waves.
(5) the metal dopant in the negative impression: characteristics of metal dopant in glass steel is mixed with metal like white impression. Cylindrical water tank all inspection items are qualified before use. Glass fiber reinforced plastic water tank how to detect?
