It can help us better guarantee the quality of the products. Therefore, we need to inspect and accept the products after purchase to ensure the quality and quantity of the products It is correct. These important operation steps cannot be ignored so that they can be used normally in the future. What should we do when we inspect and accept the product?
1. Acceptance personnel include warehouse keeper, laboratory technician and batch leader of mixing station. Under normal circumstances, the acceptance time is about 1.5 hours.
2. After the vehicle enters the factory, the inspector first climbs on the top of the car and inspects the top bag of the rubber-coated polyurethane rubber roller. After the vehicle enters the factory, the inspector first climbs on the top of the car to check the agglomeration in the top bag of the car Happening.
3. If the number of obviously agglomerated bags in the rubberized polyurethane roller bag does not exceed 10% of the total number of surface bags, it can be used.
4. If the above inspection is qualified, it will be put into storage. Check for agglomeration during storage and unloading.
When accepting this product, the polyurethane adhesive should be accurate, and every step has an inevitable connection. Whether it is the time of acceptance, preparation before and after entering the factory, or whether it is qualified or not, we should take it seriously to ensure quality. At present, we mainly use micrometers and dial indicators to measure polyurethane rubber rollers. Due to the soft surface texture of the rubber rollers, the contact measurement method will inevitably lead to greater errors.
