Our company is Zhengzhou Leizhan Technology Paper Machinery Co., Ltd, is specializing in pulp and paper equipment design, manufacturing and sales. We are professional in developing pulp and paper equipment, such as crushing equipment, screening equipment, slag removal equipment, refining equipment.
The forming device is also called the wire section, it is the most important part of the paper machine. The paper suspension forms a sheet of paper on top of it. Quality of the paper and the normal production of the paper machine are closely related to the operation of the forming device.
Once wet web is formed in the forming device, the waving state of fiber in paper basiclly inalize the design, and the physical properties of the paper are also determined. Subsequently, the press, drying and calendering of the paper machine can only limitedly improve the properties of formed sheets. The forming device is usually the most complicated part of the paper machine. In operation, the power consumption and maintenance cost of the forming device occupy a considerable proportion in the whole paper machine.
The Function of Wire Section
Get a well-organized wet sheet
The forming of a paper web is a complex process,which can usually be simply regarded as the gradual deposition of fibers onto the web of the forming mesh. To obtain uniform sheet, in addition to need good flow equipment, also need to make paper material reasonable dehydration process in forming surface. In general, the fibers can be dispersed evenly by controlling the difference between the speed of the network and the speed of the pulp, and by selecting the appropriate dewatering element.
The formed paper is dried to a certain degree of dryness
After forming, the wet paper generally needs to be dried by forced dehydration (vacuum suction, press, etc.) to achieve certain dryness or humidity so that it can be stripped off the web.
