my country's paper industry has developed very rapidly in recent years. Similarly, the application of frequency converters in the transmission system of paper machines is becoming more and more common. This article introduces several commonly used frequency converter parameters and setting methods i
There will be short heads in the drying section of the paper machine. Even if the wet paper sheets entering the drying section have a dryness of more than 32%, they have a certain strength. Let's take a look at the main reasons for the breakage of the drying section of the paper machine with the edi
The tearing degree of the paper depends on the fiber length and the fiber wall thickness. The fibers with the fiber wall thickness can only form paper sheets with high bulk and rough surface under the current conditions of thick beating, and it is difficult to improve the bursting strength and tensile strength of the paper. Quality indicators such as strength and folding resistance.
The dryness of the wet paper out of the press section is generally only 30%~40%. In the new paper machine with compound press, the dryness is only 40%~50%. Therefore, it is necessary to use the drying cylinder to evaporate the water to make the paper dry. increased to 92%~95%.
