Necessity and selection of corrosion-resistant handle in biological room of chemical experiment
In modern laboratories, safety facilities are one of the most important components. As door handles and cabinet handles frequently used in laboratories, they also need to have high safety standards and protective performance. Especially in chemical laboratories and biological laboratories, we often come into contact with all kinds of acid and alkali substances and organic solvents, which requires high mechanical strength of the handle and good corrosion resistance. Therefore, it is particularly important to use handles made of corrosion-resistant materials in these environments.
1. What is a corrosion-resistant material?
Corrosion-resistant material refers to a kind of special metal or nonmetal material that can resist the erosion of external environmental factors (such as water, oxygen and chemicals) and keep its original performance unchanged. Common corrosion-resistant materials include stainless steel, polytetrafluoroethylene (PTFE), ABS plastic and so on. They not only have excellent mechanical properties and processability, but also can be exposed to harsh conditions for a long time without obvious damage.
Second, why do you need to use corrosion-resistant handles?
1. Prolonged service life: Because there are a lot of corrosive gases and liquids in the laboratory, the handle made of ordinary materials is prone to rust, which further affects the structural stability of the whole device. The use of materials with strong corrosion resistance can avoid these problems to some extent.
2. Ensure the health of the operator: when some toxic and harmful substances are attached to the surface of the ordinary handle, they may enter the human body through skin contact and cause toxic reactions; In addition, long-term contact can also lead to allergies and other problems. In contrast, materials with good corrosion resistance are less likely to adsorb pollutants.
3. Improve work efficiency: During the experiment, if the equipment can't be opened because the handle is damaged, the whole experiment process will be blocked or even interrupted. Therefore, it is very important to choose suitable durable accessories.
Third, how to choose a suitable corrosion-resistant material?
In practical application, the types of required materials should be determined according to specific needs:
1. Stainless steel: suitable for most inorganic acid-base solutions.
In the scene, the price is moderate but the weight is large;
2. PTFE/ Teflon: It has excellent chemical resistance, low friction coefficient and other characteristics, and is very suitable for use as a protective layer when it comes into contact with strongly corrosive media;
3. ABS engineering-grade resin is a light, low-cost and easy-to-maintain alternative.
4. Alloy copper: It can also be considered in some cases where aesthetics is pursued. It also has good anti-corrosion effect but the price is expensive.
To sum up, the selection of corrosion-resistant door handles suitable for laboratory use should be comprehensively considered from various aspects, and reasonable judgment should be made in combination with specific conditions to achieve the optimal configuration goal.
