With the continuous improvement of the requirements for paper quality, and the emergence of high-speed modern paper machines, the requirements for sizing systems are getting higher and higher, and the sizing system of paper machines is also known as flow system or short cycle system in China, which is a very important process in modern papermaking technology.
Product Details
With the continuous improvement of the requirements for paper quality, and the emergence of high-speed modern paper machines, the requirements for sizing systems are getting higher and higher, and the sizing system of paper machines is also known as flow system or short cycle system in China, which is a very important process in modern papermaking technology. Including slurry mixing, purification, screening, degassing, circulation, flow and other processes. There are combinations of various processes such as multi-stage desanding, multi-stage screening, vacuum degassing, etc.
A good sizing system must meet the following requirements:
(1) Ensure that the system runs smoothly and controls stably.
(2) The amount of slurry feeding is constant, and the slurry pressure pulse is reduced.
(3) All kinds of fibers, fillers, chemicals, white water are mixed evenly to avoid slurry agglomeration, deposition and flocculation.
(4) The slurry degassing effect should be good and the concentration should be stable. (5) The system is easy to clean. The process is simple and the investment is economical.
Now the major foreign papermaking equipment supply companies such as Metso, Voith, Andritz, etc. have manufactured sophisticated equipment, such as: low-pulse sizing pump, high-efficiency desanding device with degassing device, low-pulse pressure screen, vacuum degassing tank, etc., these single equipment can meet the quality requirements of various papers, this article only on the equipment pipeline layout of the sizing system, and other non-standard equipment design for reference, for many domestic papermaking enterprises in the system design or transformation of reference.
The influence of the sizing system on the quality of the paper sheet
The longitudinal quantitative change in the paper page is caused by the pulses generated by the sizing system, which are inherent to the device itself and cannot be completely eliminated. According to reports, if the design of the sizing system is not reasonable, the longitudinal quantitative difference of the paper page can reach 8~10%, on the other hand, if the slurry in the sizing system has air bubbles, it will form needle holes or small holes on the page, stains of anionic adhesive, etc., which will have a great impact on the quality of the paper (especially for the whole page).
