Embodiment Construction

[0013] The present invention will be described in further detail below in combination with specific embodiments.

[0014] Prepare 100 weight units of resin glue, 48 weight units of curing agent, and 2 weight units of pigment. Stir the above-mentioned raw materials evenly, and then use the uniformly stirred raw materials to coat the welding points of the gas sensor, and then place the gas sensor coated with the above-mentioned raw materials in a natural environment to dry.

[0015] In the specific implementation, the amount of curing agent has a decisive effect on the length of drying time. In order to make the drying time more in line with the requirements, other drying methods such as artificial air drying can be carried out. The selection of pigments is very arbitrary. The amount of weight involved has a direct effect on the color intensity of the coated solder joint. Although the ratio of resin glue, corresponding curing agent and pigment has great arbitrariness, the ratio...

Abstract

A method for protecting the soldered dot of gas sensor includes such steps as preparing resin, coating it on said soldered dot, and drying.

Description

technical field [0001] The invention relates to a method for protecting a welding point, in particular to a method for protecting a gas sensor welding point. Background technique [0002] As a common sensor to ensure the safety of production and life, the gas sensor is generally exposed to corrosive gases in its working environment, and sometimes even the gas sensor will encounter mechanical vibration, while the welding of the existing gas sensor Points are generally exposed and lack the necessary protective measures. Therefore existing gas sensor has following shortcoming: [0003] 1. The mechanical strength of the gas sensor is not high, and it is easily damaged by mechanical vibration. [0004] 2. The anti-corrosion and anti-radiation ability is weak, and it is easy to reduce the sensitivity of the gas sensor or even lose its function if it is in a corrosive and oxidative environment for a long time. Utility model content [0005] The problems to be solved by the inv...
