Description

Technical Field

[0001] The utility model relates to the field of detection devices, in particular to a device for detecting the impermeability of epoxy primers. Background Art

[0002] Epoxy primer is applied to the surface of various pipes and machines to provide anti-rust shielding protection, resistance to chemical fumes and chemical spills, and good wear resistance. It is an ideal coating for moderately corrosive environments and where fast drying / quick recoating is required.

[0003] Existing coatings are tested for various properties when put into daily production, such as water resistance testing. The existing test first applies epoxy primer coating to the surface of the concrete with a manual brush, and then places the concrete test block coated with epoxy primer coating on the mold base of the test table. The mold body is then buckled on the mold base, the mold body and the mold base are pressed tightly, and the water measuring electrode is in contact with the concrete test block. Then, water is injected into the mold body using the water injection device in the test table, and the water pressure is continuously changed. When the water pressure is greater than the water resistance pressure of the concrete test block, the pressurized water passes through the interior of the concrete test block and water seepage occurs on the surface of the concrete test block. At this time, the water measuring electrode generates a water seepage signal and transmits the water seepage signal to the test monitoring module for analysis, calculation and evaluation. When testing concrete coated with epoxy primer coating, manual hand brushing of the concrete surface may cause uneven application of the epoxy primer coating, resulting in large errors in the test results.

[0004] Therefore, it is necessary to provide a new detection device for the anti-permeability of epoxy primer to solve the above technical problems. Utility Model Content
