Shandong Gaomi Lianchi Protective Products introduces the leather care of safety shoes

Leather care of safety shoes refers to a series of care work such as cleaning, maintenance, polishing, polishing, and color compensation of the parts of safety shoes, work shoes, and labor protection shoes made of leather. Restore the leather of safety shoes to a beautiful new look. And extend the life of the leather safety shoes. For the cleaning and care of safety shoe leather, use detergents and care agents whose pH value should be between 5-7.5, otherwise, if the pH value is greater than 7.5 or less than 5, the internal structure of the leather of the safety shoe will be damaged and shortened. The life of the leather.      The basic reason why the leather of safety shoes is soft is that when tanning, grease is introduced into the inside of animal skins to form an oil film covering the surface of the fibers in the skin, that is, a layer of oil film of appropriate thickness is used between the surfaces of the fibers in the skin. Open, the friction force between the internal fibers of such leather is equivalent to the friction force of oil molecules, so the safety shoe leather will be very soft. The principle is similar to that of sponge. The difference is that the inner surface of the dermis of safety shoes is separated by an oil film, so that there are slidable pores inside the dermis, but its pores are smaller than sponges and there is no distribution of fibers on the inner surface of the dermis. The sponge is so regular.       However, the oil introduced into the leather of safety shoes will slowly evaporate and lose over time under natural conditions, or the oil film will be destroyed due to other reasons. If it is hydrolyzed in water or under high temperature, the oil film will be destroyed. When the grease evaporates and loses, the surface between the inner fibers of the leather of the safety shoes should be injected with fine grease that forms an oil film.
