1.?Pls confirm this paper sample is ordenary corrugated paper or high strength corrugated paper , confirm the sample is correct.?
2.?Due to the long-term paper break of the paper machine, the spray water from the sizing roller entered the starch tank, which caused the concentration and temperature to decrease, and the sizing effect became poor and was not detected.
3.During the start-up process, the surface sizing pump is damaged or the pipeline is broken or blocked, causing it to be unable to be added.
4.The finished paper has been placed in the warehouse for too long, causing the sizing effect to decline.
5.The surface layer of the paper roll is exposed to the sun to cause rapid attenuation, and the inner layer may be qualified.
6.?The sizing agent has been left in the manufacturer for too long or the ambient temperature is too high, resulting in deterioration and loss of effect.
7.False sizing occurs during the production process.
Customers can select the paper inside the roll, heat it in the oven at 105 degrees Celsius for two minutes, and then take it out for testing. If it works, it is a false sizing phenomenon. If there is no change, consider the problem of the sizing process?(generally referred to as AKD sizing )
