      What are the principles of selecting tin barrel?

      2021-01-06 425

      The coating packaging barrel is widely used in the world. With the careful design and manufacture of the coating packaging barrel manufacturer, the coating packaging barrel is convenient for loading and bearing large weight. It is suitable for the needs of medium-sized clients and has a wide range of applications. It can be used for the loading and transportation of liquid, semi liquid, powder, solid and other raw materials.

      What principles should be mastered when selecting the coating packaging barrel?

      First, according to the local high temperature, low temperature, roof slope and service conditions, the waterproof coating with heat resistance and low temperature flexibility should be selected for the coating packaging barrel. The waterproof coating with high heat resistance shall be selected for the coating packaging bucket in high temperature area to prevent flow; the waterproof coating with good low temperature flexibility shall be selected for the coating packaging bucket in severe cold area to avoid cold brittleness.

      Secondly, according to the degree of foundation deformation, structural form, local annual temperature difference, daily temperature difference and vibration factors, the waterproof coating with the same tensile function should be selected for the coating packaging barrel. For the roof with large structural deformation, the waterproof coating with large elongation should be selected for the coating packaging barrel to get used to deformation.

      Third, according to the exposure degree of the waterproof coating on the roof, the coating packaging barrel should select the waterproof coating with UV resistance and heat aging persistence rate. For exposed roof, UV resistant waterproof coating should be selected for coating packaging barrel to improve service life.

      4、 When the roof drainage slope is greater than 25%, the waterproof coating with long drying time should not be used for the coating packaging bucket.

      This is the principle of selecting the coating packaging barrel. Mastering the above principles when selecting the coating packaging barrel can provide us with many conveniences in using the coating packaging barrel and coating in the future.
