Chemical protective gloves
It is an indispensable part of chemical production and can protect the health of workers. Many people know chemical protective gloves, but they don't know enough about it. Here are eight kinds of chemical protection gloves materials, and a brief description of their related common sense.
The first: natural latex
Generally speaking, natural latex has better protection for aqueous solutions, such as acid and alkaline aqueous solutions. Its advantages are comfort, good elasticity and flexible use.
The second kind: Nitrile
It has good protective properties against oil, grease, petrochemical products, lubricants and various solvents. However, swelling may occur in some solvents, affecting its physical properties and reducing protection.
The third type: polyvinyl chloride (PVC)
It has a protective effect on a large number of water-soluble chemical substances, such as acids and alkalis, but it cannot protect organic substances such as solvents, because many solvents will dissolve the plasticizers in it, which will not only cause pollution, but also greatly reduce the barrier function of gloves.
It is almost as comfortable as natural rubber. It has good protection for petrochemical products and lubricants, it can resist ozone and ultraviolet rays, and also has strong anti-aging properties.
Fifth: polyvinyl alcohol:
It has a good protective effect on most organic solvents, but it is easily soluble in water, and its effectiveness will be reduced after encountering water, and the material is hard and inconvenient to process.
Sixth: butyl synthetic rubber
It has a good protective effect on organic compounds and strong acids. It is difficult to produce and process. It has almost no protective effect on oils and fats, but it has particularly good protective properties on gases.
Seventh: Fluorine rubber
Fluorinated polymer, the substrate is similar to Teflon (polytetrafluoroethylene), and its surface activation energy is low, so the droplets will not stay on the surface, which can prevent chemical penetration. It is very useful for chlorine-containing solvents and aromatic hydrocarbons. Good protective effect.
Eighth: Chlorosulfonated polyethylene:
It has protective properties for most chemical substances, can protect alkalis, oils, fuels and many solvents, and has good resistance to high and low temperatures, wear resistance, bending resistance and so on.
The most commonly used are mainly natural latex, butyronitrile, and polyvinyl chloride (PVC) for knitting glove cores.
