Papermaking machinery is a machine that includes raw material preparation, pulping, papermaking, until it is made into a finished roll or sheet, as well as processing paper and cardboard. Papermaking dewatering equipment is an essential element used in papermaking dewatering.Paper is one of the four
The paper machinery industry is defined as machinery that includes raw material preparation, pulping, papermaking, up to roll or sheet finished products, and processing paper and board. For more details, the following is the definition and classification of the paper machinery industry compiled by Xiaobian.
The working environment of the paper machine is humid and high temperature, and some equipment is also accompanied by impact loads. Therefore, the choice of lubricant mainly considers its emulsification, water resistance, heat-resistant oxidation stability and load resistance.
The composition of the wire section of the Fourdrinier paper machine:The wire part of the Fourdrinier paper machine is referred to as the Fourdrinier wire or the wire case for short. It is a typical fourdrinier network department. The main component of the net case is an endless fine woven net.
The wet suction box on the paper machine is a low vacuum dewatering element with a vacuum degree of 0.2-1kPa. The box surface is composed of multiple chopping boards, and there are also open-hole panels. The opening rate is more than 50%. The material is the same as the chopping board.
Dewatering process of vacuum suction box of Fourdrinier paper machineOn the vacuum water tank of the paper machine, the wet paper web has been basically shaped, and its main purpose is to dewater.For the vacuum suction box at low speed and low vacuum, the dehydration process of the wet paper web on a vacuum suction box can be roughly divided into three stages.
