Different material labor protection gloves（1）
In the laboratory, people need to conduct various experiments, and each experiment is accompanied by risks. Therefore, in order to better protect themselves, people will use different labor protection products to protect every part of the body.
As the most vulnerable part of the external injury, the hand needs people to protect it well. Therefore, people are more cautious when choosing hand protective gloves.
In the laboratory, commonly used labor protection gloves are divided according to the material, which can be divided into: natural latex, nitrile rubber, natural rubber, PVC (polyvinyl chloride), PVA (the surface is coated with polyvinyl alcohol), polybutadiene rubber, butadiene rubber Base rubber, leather, cloth and so on.
So, faced with so many categories of laboratory gloves, how should people choose?
In fact, no matter what kind of labor protection gloves you choose to use in the workplace, you need to adapt to local conditions and choose according to actual needs.
Therefore, when people choose laboratory gloves, they can start from two aspects. One is the danger faced by the hands during the experiment, and the other is the advantages and disadvantages of laboratory gloves of different materials. Only through these two points, I believe people can choose suitable laboratory gloves.
So, what are the advantages and disadvantages of laboratory gloves made of different materials?
1. Natural latex:
Advantages: It has anti-slip grip, heat insulation, tear resistance, puncture resistance, wear resistance and cut resistance, and has good protection against water-based chemical products (such as acid and alkali aqueous solutions), and it is easy to wear Comfortable and elastic, so it is often used in oil-free working environment.
Disadvantages: The protection against organic solvents is not good enough, and it is not oil resistant. At the same time, it may cause allergies to some people, because some users are allergic to milk protein.
2. Nitrile rubber
Advantages: This is the most common material in laboratory protective gloves. It can not only prevent the erosion of oil (including animal fat), xylene, polyethylene and aliphatic solvents, but also waterproof, resistant to acids, alkalis and Alcohol solvent, which has the advantages of high wear resistance, good heat resistance, low chemical residue on the surface, good flexibility and good sensitivity.
Disadvantages: Can't resist most ketones and aromatic chemicals, can't be used in high-temperature workplaces, and can't be used as insulating gloves.
3. Natural rubber
Advantages: It has an effective protective effect on alkalis, alcohols and various chemical dilute aqueous solutions (such as dilute acids and dilute alkalis), and can better prevent the penetration of aldehydes and ketones. Therefore, it is often used to clean laboratory utensils and instruments.
Disadvantages: poor protection against oils and organic compounds, and insufficient flexibility and sensitivity when wearing gloves.
Advantages: It has strong chemical corrosion resistance, and it has a protective effect on a large number of water machine solvent chemicals (such as acids, alkalis, amines, peroxides, etc.).
Disadvantages: It has no protective effect on organic solvents. If PVC gloves are used in organic solvents, it will cause the plasticizer in the gloves to dissolve, so that chemicals can quickly penetrate the hands. If you use pvc gloves in high temperature, it will cause the gloves to decompose and produce vinyl chloride (VCM).
