Analysis and improvement method of water tank insulation defect of stainless steel, stainless steel heat preservation water tank as the water storage device is the most popular, its sales continued to increase must be under the premise of quality assurance to carry forward, otherwise, just empty talk, any kind of products in the world are not perfect in every respect, stainless steel heat preservation water tank also has its defects. As a manufacturer, to find out the product defects and treat specific conditions in order to achieve the perfect product, then how the defect inspection of stainless steel heat preservation water tank? Stainless steel insulation tank defects mainly in what place?
A method for defect inspection of stainless steel water tank insulation is the main instrument test method; X ray inspection, inspection of common glass steel products defects such as cracks, delamination, resin concentration, loose and wrinkles, metallic inclusions etc..
Two, stainless steel insulation tank defects mainly in 5 aspects;
Loose - that is, to reduce the density of a local product, there are small pores irregularly distributed, or a small crack, the presence of small resin concentration. The film features, irregular shaped patches of black clouds. According to the different direction - fold into circumferential folds (circumferential distribution along the axial wrinkles (products) and products along the axial direction). The film features a wavy.
The metallic inclusions in glass fiber reinforced plastics are characterized by a white image with the same shape as the inclusions. Cylindrical water tank inspection items are qualified before use.
Crack or delamination: mainly refers to the separation between the fracture and the cloth cloth layer, image feature film: crack or delamination in laminated sheet is flat and two sharp or zigzag black lines; winding crack or delamination in the products are straight or slightly wavy black lines. The middle or wide, pointed at both ends of spindle "image; the crack shape of molded products, because the product shape varies, mostly two pointed Black Curved line.
Resin aggregation - that is, a certain part of the resin is too much, the film image characteristics and cracks or stratification similar, but the same degree of crack image contrast is small, and the image contour is not clear.
