Selection scope of sealing material in scrap metal baler
In the scrap metal packaging machine, because of the performance difference of the sealing material itself, the sealing performance of the seals manufactured is also very different. Therefore, when selecting the sealing material for scrap metal baler, the first consideration is its permeability. Friction is unavoidable in dynamic seal. The magnitude of friction is related to material, fluid type, fluid pressure, working temperature, speed, surface roughness of seal surface and other factors. It directly affects the sealing performance and life of seal.
Secondly, the tensile strength of scrap metal packaging sealing materials generally decreases with the increase of temperature, so we must consider its maximum use temperature and mechanical strength at high temperature; the wear resistance of materials is also an important performance of dynamic sealing parts, good wear resistance, long service life. The higher the hardness, the more wearable.
Hardness is an important index of sealing materials for waste metal packaging. It should be determined according to the roughness of the sealing surface. Rough sealing surface and low hardness of the sealing parts make the sealing effect better. At high sealing pressure, the hardness of the seals should be increased. In addition, of course, there are material temperature resistance, also affect the use of sealing materials, so scrap metal packaging machine should choose a wider range of temperature materials.
