The quality management of heat shrinkable belt and heat shrinkable belt is mainly reflected in the following aspects: first, strictly manage the material quality and test the quality according to the national industry standards. Main standards of heat shrinkable tape and heat shrinkable tape products. People follow the rules of the product guide.
The thickness, thickness, expansion and cathode separation of heat shrinkable tape and heat shrinkable winding tape shall be strictly checked, and the surface layer shall be free from wrinkles, bubbles and scratches. These people often have inspectors in the production process and after the production and production tasks. People have their own laboratories and product developers to test products strictly.
Processing technology guide. In the production process and after production, it is necessary to carry out strict processing technology test to see whether the production of the product is suitable for the processing rules, if not, immediately improve. It is necessary to meet the relevant processing rules of production line equipment. Before the production of heat shrinkable tape and heat shrinkable tape, it is necessary to check whether the machine and equipment are normal, the ambient temperature, the final speed, and the standard must be set according to strict standards. Or the personnel should record the statistical data of the production line equipment.
Control the production process. In the production process, it is necessary to check the implementation of specification of heat shrinkable tape and heat shrinkable sleeve. If the thickness is inconsistent or there are bubbles on the surface during the production, stop the problem in time and report to the leader or make a record. Product processing technology testing. The heat shrinkable belt and heat shrinkable belt of each batch of production and production task shall be undertaken by quality inspection personnel and tested according to national industry standards. If it's not very good, you need to extract tests multiple times, and the product is not allowed to be bad.
Because solvent-free epoxy coating has double-layer function, it is not only anticorrosive material but also binder. Therefore, it is necessary to brush the top coat in the roughened area. It is necessary to equip the heat shrinkable belt when the topcoat is still wet, so as to ensure the adhesion between the hot-melt adhesive and the topcoat. When brushing, we try our best to make the total width of the topcoat slightly exceed the total width of the overheated shrinkage band or heat shrinkable sleeve.
However, at present, the quality of heat shrinkable sleeve continues to make progress. The first-class root cause of short production cycle time and low price of large-scale heat shrinkable sleeve and other large and medium-sized projects such as the second west to east gas pipeline project choose the heat shrinkable sleeve as the raw material for joint coating, and the heat shrinkable sleeve has become a registered product of raw material enterprises for anticorrosion and joint coating of steel pipes.
