The forming quality habits of the egg tray machine are classified as good or poor, and the criteria for classification are the degree of homogeneity of the egg tray or the degree of fiber distribution. The storage, flow and forming structure and performance of the egg tray equipment in the beating system of the egg tray equipment affect the fiber distribution in the paper molding products to a certain extent. The sign of good or bad molding is the uniformity of fiber distribution, which is a common molding quality item. It requires that the fiber concentration is the same microscopically within a certain area arbitrarily selected on the egg tray. The closer the fiber distribution is to this ideal state, the more homogeneous it is. In fact, the non-oriented arrangement and uniform distribution of fibers can only be achieved by applying sufficient agitation in a very thin fiber suspension. He behaves as a dynamic balance of fiber diffusion in all directions of the suspension. However, when molding paper products, The consistency of the pulp is greater than that of the paper when it is made, so it is difficult to achieve a uniform degree of the paper.

The morphology of rhenium fibers and other solid substances in the deposited layer also has a great impact on the quality of paper molded products.

First, the density of the layer depends on the type of fiber and the beating and molding conditions. It determines the air permeability and bulk of the egg tray.

Second, the degree of fiber entanglement determines the thickness and horizontal strength of the egg tray.

Third, the obvious structural difference between the surface part and the middle part of the laminated layer and the difference between the filtering surface and the non-filtering surface are due to the low retention rate of fine particles, fillers, additives and other solid particles on the filtering surface. After the filter layer is formed on the filter surface, the retention rate in the thickness direction gradually increases, resulting in

Fourth, the orientation of the fiber arrangement determines the anisotropy of the egg tray

In short, during the operation of the egg tray production line, the forming quality of the egg tray is closely related to many factors. The mastering of the entire technology requires professional technical training and guidance!
