(2019 Shandong trip)Linyi Dingxu Packaging Paper Products Co., Ltd.
Address: Jinchang Community, Jiehu Town, Yinan County, Linyi City, Shandong Province
Machine model: CH48KW
Quantity: 1
Application: boil glue
Solution: Add 800 kilograms of water and 70 kilograms of glue to boil in a 1 ton container. The steam produced by 48KW equipment enters the container through the pipeline and heats it for 1.5 hours. After stirring 1.5, it can be put into the glue pool of the reel.The paper is fixed into a cylinder after being covered with glue in the glue pool on one side of the drum in the reel machine, and finally molded for chemical products.
Customer feedback: Water treatment will not be installed
Solving the problem: When purchasing the equipment, it was equipped with a water treatment device, but they never knew how to install it, so they never used it. Today, Master Wu helped the company install it, and then trained it, explaining the precautions for use and the working principle of water treatment. In addition, the customer's sewage outlet is blocked and the sewage is not discharged smoothly. The after-sales master teaches the correct method of sewage discharge on site.
