Many industries need to wear safety shoes. With the advancement of technology, the safety of safety shoes is gradually improved, and the appearance is more and more fashionable. What kind of safety shoes should we buy as a decoration worker or plating worker?
Let's take a look at what you need to pay attention to when purchasing safety shoes.
1. The working environment determines the function of purchasing safety shoes
Safety shoes should be selected according to the working environment, and the functional requirements of safety shoes are different in different positions. Safety shoes have the following functions: anti-smashing, anti-piercing, anti-static, anti-slip, oil resistant, high temperature resistant and insulating.
Every industry generally has multiple functions for safety shoes, so the regular safety shoes on the market are also compound and versatile.
For example, the staff of pipeline construction generally wear safety shoes that are resistant to acid, alkali, oil, slip and water. The working environment of construction workers is more complicated. According to different jobs, shoes with different functions are required. The most needed functions are anti-smashing, anti-piercing and anti-slip. Electrical insulation or power operation requires electrical insulation.
2. Shoe selection method for safety shoes
Safety shoes sole material is divided into rubber and PU
The rubber sole is resistant to hydrolysis, oil, high temperature, weak acid and alkali, and rust-proof, and is suitable for harsh environments. The bottom of the PU is also divided into a single-density PU bottom, a double-density PU bottom, and a now popular PU+ rubber sole. The single-density PU bottom is relatively inferior in toughness and elasticity compared to the double-density PU bottom, and the service life is also relatively short. The double PU bottom safety shoes are lighter, more wear-resistant, and have a longer life than a single PU bottom. The workmanship is more complicated than the work of a single PU bottom.
The PU+ rubber sole can be regarded as the most practical type of safety shoe sole on the market. Light weight, make up for the defects of PU outsole wear and stab resistance, retain the comfortable soft and soft feeling of the elastic layer PU, increase the wear resistance and stab resistance of the rubber layer of the wear layer, and greatly extend the sole The damage cycle.
If the safety shoes are required to have anti-slip performance requirements, the sole design should be analyzed while considering the material and density of the sole.
3. Safety shoes anti-smashing Baotou purchase
The anti-mite head is divided into a steel toe cap, a steel-coated toe cap and a new type of toe cap made of composite material.
The steel head is heavy, and the steel toe cap is lighter. Under the same index, the two types of toe caps have the same compressive strength. However, under the same impact, the shape recovery ability of the plastic steel toe cap is better than that of the steel toe cap, so the plastic steel toe cap is more durable.
Since the steel sheet is electrically conductive, the general insulated safety shoes are made of plastic steel toe caps, but the steel toe caps can also be used in insulated safety shoes after being wrapped by an insulating material.
4. Safety shoes tongue purchase
Safety shoes The tongue is divided into split and connected tongues. Split-type tongues are often used in sneakers and running shoes. The tongue and the upper are separated from the upper and lower or the left and right. The connected tongue is required to prevent the left and right deviation of the tongue according to certain working environments. The tongue and the upper are joined together to help prevent wind and sand, but the comfort is worse than the split tongue.
