Surface drying time detection device

Technical Field

The utility model relates to a detection device technical field, concretely relates to table is done time detection device.

Background

The RTV coating is short for long-acting anti-pollution flashover coating of room temperature vulcanized silicone rubber. The RTV coating is a novel hydrophobic coating which takes room temperature vulcanized silicone rubber as a basic raw material, and can be cured into a rubber-like film at normal temperature after being coated on the surface of the insulator, and the RTV coating firmly covers the surface of the insulator, so that the pollution flashover voltage of the insulator can be obviously improved.

The RTV coating surface drying time has important influence on the coating performance and the construction process and is an essential item of coating test. According to the requirements of GB/T627 'Normal temperature curing Silicone rubber anti-pollution flashover coating' standard, a surface drying time test is an essential item of a sampling test and a type test.

The standard specifies that the qualified range of the surface drying time is 25min-45min under the conditions of 25 +/-2 ℃ and 40% -70% RH. The test method recommended in the GB/T627 standard is a small glass ball method, which is given by GB/T6753.2 Small glass ball method for paint surface drying test, each test requires a plurality of small glass balls, a soft brush, a glass tube and the like, and the operation is complex and the time consumption is long. When the surface drying time is measured by the small glass bead method, several test samples need to be prepared because damage may be caused to the surfaces of the test samples when the paint film is lightly brushed with a soft brush, which increases the test workload for measuring the surface drying time.

In summary, a surface drying time detection device is needed to effectively test the surface drying time of the RTV coating, reduce the test workload, and improve the test efficiency.
