Talk about the reasons for the warpage of impregnated paper.


The solution of the full ceramic veneer of the impregnated paper is based on the melting, spreading and drying of the epoxy resin on the impregnated paper to produce a symmetrical closed surface. Only when the temperature and the IH of the working pressure are really matched with each other, can a firm bonding Compressive strength and excellent surface characteristics, briefly describe the reasons for the warpage of the impregnated paper.

1. The wrong stacking of pressed products is another key reason for the warping of the board. The treatment method is to use symmetrical and vertical slides or trays to store the pressed impregnated paper and make it stick to the panel.

2. From the perspective of the raw material itself, the characteristics of the double-layer impregnated paper commonly used in the village material are different, which will also cause the board to warp. If single-sided and double-sided paper is used, warping is an inevitable result. From a manufacturing point of view, We can apply the same impregnated paper or adjust the appropriate temperature difference between the upper and lower pressure plates to ensure that the plate will not warp.

3. From the perspective of pressing, the warping of the plate is due to the excessive temperature difference between the upper and lower pressure plates, which leads to different drying speeds of the tapes on both sides of the plate during pressing. The plate bends to the side with the faster speed. The suitable temperature difference between the upper pressure plate and the lower pressure plate should be 3~5 higher than the lower pressure plate.

Impregnated paper manufacturers: what are the requirements for impregnated paper paving?

Impregnated paper has good fire prevention, high temperature resistance, earthquake resistance, mildew resistance and recycling characteristics. Generally, this kind of melamine paper board is cleaned casually and completely fulfills the regulations of energy saving, emission reduction and environmental protection. It is called green ecological paper. According to the participation of melamine paper in high-end customized wardrobes, it is more corrosion-resistant, less likely to cause ecological environment problems, and is deeply loved by many groups.

Impregnated paper is made by soaking melamine on decorative pattern paper, drying and hot pressing. Melamine is a formaldehyde-free aqueous solution. According to one-time hot pressing, it is not easy to cause environmental pollution. In addition, it also reduces the board that is generally favored by everyone. Put. impregnated paper laying requirements:

1. The moisture content of the board should be controlled within the range of 6-10%, because the key of the plywood is optional, and environmental damage will cause the moisture content of the cardboard to change.

If the water content is too high, it may cause sniping, leveling, etc. If the water content is low, or the content of volatile organic compounds in the impregnated paper is low, the surface will not be easily wetted during the entire process of hot pressing.

Cardboard level:

2. The surface of the cardboard is smooth, no water marks and oil stains are allowed, and there are no reasonable specifications such as dragging and shovel.

3. The thickness error of the plate should not exceed 0.2mm, the stainless steel should be polished evenly, and sand leakage is not allowed.

Let's talk about it today. The above is the reason for the warping of impregnated paper explained by the editor. I hope the above explanation will be helpful to everyone. Thank you for watching. If you want to know more about it, welcome to call.

Introduction to the advantages of impregnated paper, come and collect!

Melamine impregnated paper is divided into three categories: plain paper, printing paper and wear-resistant paper. According to the product application, it can be divided into two categories: face paper and base paper. Ordinary paper is different from original color paper and printing paper. The base paper is good, pure in color, not easy to change color, and the color of printing paper is relatively uneven. Generally, plain printing paper is used as base paper (multi-purpose laminate flooring, also called balance paper), which is widely used in cabinets and laminate flooring.

What is the development history of melamine impregnated paper? Let's take a brief analysis. Melamine impregnated paper is generally used for panel furniture, most of which are low-pressure and short-cycle forms, that is, the board is made by pressing for tens of seconds under high temperature and high pressure. In recent years, the synchronous disk produced by combining gelatin paper with steel plate and wood grain has been loved by people because of its good body texture.
