Embodiment Construction

[0017] refer to figure 2 , image 3 and Figure 4 , a failure alarm device and method for liquid-tight protective clothing according to the present invention are described in detail.

[0018] A failure alarm device for liquid-tight protective clothing, such as figure 2 and image 3 As shown, at least one failure alarm device is adhered to the outer surface of the liquid-tight protective clothing 1. The failure alarm device includes a humidity sensor 2 and a single-chip arithmetic processing module 3. The humidity sensor 2 is wrapped with a failure detection material layer 4 outside. The material of the material layer 4 is the same as that of the liquid-tight protective clothing 1, the thickness of the failure detection material layer 4 is smaller than the thickness of the original liquid-tight protective clothing 1, and the humidity sensor 2 is connected to the single-chip arithmetic processing module 3 through the multivibrator 5, The single-chip arithmetic processing m...

Abstract

The invention belongs to the technical field of skin protection equipment, relates to failure detection of protective clothing, specifically a failure alarm device and method for liquid-tight protective clothing, which solves the technical problems in the background technology, and includes a humidity sensor and a single-chip microcomputer Operation processing module, the humidity sensor is wrapped with a failure detection material layer, the thickness of the failure detection material layer is less than the thickness of the original liquid-tight protective clothing, the humidity sensor is connected to the single-chip computer processing module through the multivibrator, and the single-chip computer processing module is also connected with A buzzer alarm circuit and a display device for displaying the switch state of the single-chip computer operation processing module. The failure alarm device and method of the present invention can improve the use safety of the protective clothing while ensuring that the protective performance and serviceability of the liquid-tight protective clothing are not reduced; and without calculating the wearing time of the protective clothing, It can also detect the protective effect of protective clothing in time, effectively guaranteeing the safety of users.

Description

technical field [0001] The invention belongs to the technical field of skin protective equipment, and relates to failure detection of protective clothing, in particular to a failure alarm device and method for liquid-tight protective clothing. Background technique [0002] Liquid-tight protective clothing refers to protective clothing used to prevent chemical liquid leakage. The protection level is B. It is mainly used in environments such as acids, alkalis, and liquid chemicals. Protective clothing is defined as limited use, that is, after decontamination. Can be used again. Liquid-tight protective clothing fabrics are mainly polymer materials, and the penetration of chemical liquids on protective clothing belongs to the activation diffusion process. The specific description of the process is that the chemical penetrates from the outer surface of the protective fabric of the outer layer of the protective clothing and diffuses into the interior of the protective fabric, and...
