What type of gloves protect you from hazardous chemicals
In chemical experiments, chemical production, and work, people will be exposed to a variety of dangerous chemical supplies, and the hands, as the most direct contact with chemical supplies, have a certain risk. The chemical gloves can avoid this problem very well. So what type of gloves protect you from hazardous chemicals?
Types of chemical gloves:
Advantages: Good physical performance, a heavy-duty model with good cutting resistance, and excellent flexibility.
Disadvantages: Poor protection against fats and organic compounds, risk of protein allergy.Easy to decompose and age.
Low cost, excellent physical performance, good flexibility, and resistance to scratch, puncture, wear, and cutting performance.
Poor protection against many ketones, some aromatic chemicals, and moderately polar compounds.
Advantages: low cost, good physical properties, minimal risk of allergic reaction.
Cons: Organic solvents wash the plasticizer off the gloves, creating "black holes" of different molecular sizes in the glove polymers, which can lead to rapid chemical penetration.
Advantages: Very strong, high chemical resistance; Good physical properties, with good resistance to scratch, puncture, wear, and cutting performance.
Disadvantages: Decomposes quickly in contact with water and light alcohols. Less flexible than many other chemical-resistant gloves; Costs are high.
Advantages: good chemical resistance.Excellent chemical resistance to oil, acid (nitric acid and sulfuric acid), alkali, a wide range of solvents (such as phenol, aniline, ethylene glycol), ketone, refrigerant, cleaning agent.Medium physical properties.
Disadvantages: hook resistance, cutting, puncture, wear resistance than nitrile rubber or natural rubber. Not recommended for use in aromatic organic solvents, the price is higher.
6. Butyl rubber gloves
Advantages: Good flexibility and excellent corrosion resistance to intermediate polar organic compounds such as aniline and phenol, glycol ethers, ketones, and aldehydes.
Disadvantages: poor protection against non-polar solvents including hydrocarbons, chlorinated hydrocarbons, and fluorinated hydrocarbons; Costs are high.
Advantages: too cold, heat, spark splash, wear, cut, puncture can carry out general protection
For general protection
Selection of gloves for chemical experiments
The proper choice of gloves and the correct use of gloves are directly related to the health of the hands. The following points should be noted in the process of selection and use:
1. Choose gloves with sufficient protective effect;
2. Before use, especially disposable gloves, check whether the gloves have holes or damage, abrasion, especially between the fingers;
3. Do not throw away contaminated gloves at will during use;
4. When taking off gloves, we must pay attention to the correct method to prevent the harmful substances contaminated by gloves from contacting the skin and clothes, causing secondary pollution;
5. Do not share gloves. Sharing gloves can easily cause cross-infection.
6. Wash your hands before putting on gloves, and wash your hands after taking off gloves, and apply some hand cream to supplement the natural protective oils;
7. Heal or cover the wound before wearing gloves to prevent bacteria and chemicals from entering the bloodstream;
8. Do not ignore any skin erythema or itching, dermatitis, and other skin diseases, if the hands appear dry, itching, bubble, etc., consult a doctor in time.
9. For better protection effect, you can choose to wear two kinds of gloves at a time, TPE gloves
+ latex gloves; Vinyl gloves + nitrile gloves.Cloth gloves + butyl rubber gloves, etc.
