Causes of water stains on impregnated paper and solutions


The impregnated paper used by everyone is a particularly practical building decoration material, but no matter how good the goods are, there are defects. In the production process of impregnated paper manufacturers, sometimes water stains appear on the surface of the goods. For this matter, we must Analyze the reasons and solve the problem.

Because the water content of the impregnated cardboard is too high, or because there are too many residual evaporation components, it may also be that the installation of the water content detection instrument is unreasonable, which makes the water content error, or the edge temperature is too low during production and processing. When the impregnated paper is stored, it will also cause water stains on its surface, so we must pay attention to the rationalization of natural environment standards during storage.

In order to ensure the quality of the impregnated film paper, high-quality decorative base paper must be used. No matter what kind of paper is tested and qualified, it can be used, but it cannot enter the production line. In the whole dipping process, the actual operation should be strictly in accordance with the processing procedures, sampling inspection every 39 minutes to ensure the technical standards of 130~150 mold clamping force, 6% ~ 7% volatile matter and 65% refractoriness. After dipping and drying, the adhesive film paper should be packed with plastic film immediately and sealed with sealing tape, stored in a warehouse with a temperature of 25C ~ 25C, an ambient humidity of 55% ~ 65% and a central air conditioner, the paper that cannot be used once should be sealed and sent to the warehouse for storage immediately to prevent the adhesive film paper from sticking together due to moisture, causing unnecessary property losses.

The main advantages of impregnated paper for furniture decoration:

In the whole process of making furniture, the surface decoration of furniture can be carried out after or before the furniture is assembled. Various decoration methods are often used in conjunction with each other. Surface decoration can make the furniture more beautiful and generous. The color, gloss and line are coordinated with the design, so that everyone can create artistic beauty and comfort. However, the surface of the furniture is covered with a certain thickness of moisture-proof, high-temperature, weather-resistant, wear-resistant and solvent-resistant protective layer, it can achieve the purpose of maintaining furniture and extending its service life.

Impregnated paper is a kind of common furniture decorative paper, which is made of various special printing paper soaked and dried by melamine resin. It can imitate various patterns and designs, clean up the appearance and cover the surface defects of the board. However, today's impregnated paper can only be used for graphic design, with no sense of hierarchy and poor decoration.

In order to improve the actual information display effect of impregnated paper, in contemporary technology, the general choice is to first print a good pattern design packaging on the printing paper, and then use the technology of hand-engraving thick steel plate to create matching concave and convex marks on the printing paper, so as to improve the actual information display effect and fidelity. But first of all, there is a certain deviation in the specifications and texture of the impregnated paper, which may lead to the inconsistency between the hand-carved pattern of the thick steel plate and the grain pattern of the wood grain paper, which affects the actual effect of the simulation.

What are the main indicators of melamine impregnated paper? Let's make a brief analysis together. 1. The amount of glue: the solid resin content of the decorative film paper (expressed as a percentage (%)). 2. Volatile content: the content (percentage (%)) of volatiles (mostly moisture and other small molecules) on decorative film paper. 3. Pre-curing degree: The curing degree of the resin is expressed as a percentage (%) on the decorative film paper.
