Firm handle of explosion-proof freezer
In the field of modern industry, with the increasing demand for safe production and people's increasing awareness of environmental protection, all kinds of safety equipment came into being. One of the most important facilities is the explosion-proof freezer, a safety cabinet for storing dangerous chemicals. As an indispensable small part of the explosion-proof freezer, the firm handle ensures that users can open it quickly and conveniently, and also ensures its safety.
First of all, we need to know what "explosion-proof" means. Simply put, it can prevent explosion accidents or reduce the harm caused by explosion under special conditions. So why use explosion-proof design on refrigerators that store flammable liquids (such as alcohol)? This is because if there is electrostatic spark or short circuit in a closed space, it is easy to cause combustion or even explosion; Moreover, these articles often have certain volatility, which may cause air pollution and other problems if they are not controlled.
In order to achieve this goal, manufacturers usually choose to use high-quality stainless steel material to manufacture the whole door frame and handle part, and make it reach the protection standard above IP65 level through special process treatment (that is, it can effectively prevent water and dust from invading). In addition, some other functions will be added, such as grounding wire interface to guide away excess charge and avoid sparks; Only by installing a temperature and humidity control system to ensure the stability of the storage environment can it be called an "explosion-proof" product in the true sense.
Next, we focus on the protagonist of this article-a firm handle. From the appearance, it is not much different from other common styles: it is generally composed of a round metal bar with a diameter of about 20mm and fixed at two side positions for high grip comfort and not easy to fall off and be damaged when operated with one hand. But in fact, there is a lot of learning in it!
1. Material selection is very important. Because of the frequent use of switches, alloy steel with moderate hardness or high-strength aluminum alloy must be selected to withstand the long-term wear test without deformation and aging;
2. Surface treatment technology is also critical. Besides conventional oxidation blackening, chromium plating/plastic spraying is also recommended to enhance corrosion resistance and prolong service life.
3. Structural optimization cannot be ignored. Adjust the installation angle reasonably to make the center line conform to ergonomics, so as to improve convenience and feel experience;
To sum up, the "solid handle" is only a small accessory, but it plays a vital role in the whole explosion-proof system. Only when every detail is fully considered can the overall performance be brought into full play to better serve the vast number of users. I hope that more high-quality products will emerge in the market in the future to meet the diversified needs of everyone!
