When choosing labor insurance shoes, perhaps few people will choose it because it looks more earthy. But for some people engaged in special jobs, it has the function of protecting feet and even protecting life, such as electricians, construction workers, etc. When workers use tools, operate machines and move materials, their feet may come into contact with heavy, hard, and angular objects, which may be injured, stabbed or crushed.
The focus of the storage of safety shoes is moisture-proof, mildew-proof and deformation-proof. Remove dust, sludge and dust from safety boots in time. If there is a crack on the shoe upper, you need to fix it, and then apply shoe polish carefully.
The upper/outsole adhesion strength standard requirements of labor insurance shoes (all rubber, except all polymer shoes): Except for sewing soles, the adhesion strength is ≥4.0n/mm. In the test, if the sole is torn, the adhesive strength is ≥3.0n/mm.
At present, the leather materials of safety shoes mainly include cowhide, crazy horse skin, cow hair, nubuck leather, imported Indian leather (lychee core), imported Brazilian cowhide (shaving leather, nubuck leather), etc.
