The cause and solution of mold in plywood
When using plywood or furniture made of plywood, people may have the situation of mold in plywood, mold in plywood will become unattractive, what is the reason for mold in plywood? How can plywood prevent mold?
First, the reasons for mold of plywood
1, many plywood on the market in the production process will use environmentally friendly glue, environmentally friendly glue contains a large number of protein components, is the bacteria like the ingredients, if all aspects of the environment to achieve certain conditions, so that plywood is easy to mold. Therefore, under normal circumstances, it is recommended to add glue anti-mildew agent to the adhesive glue, which can prevent the product from mildew.
2, plywood moisture is too high will lead to plywood easy to mold, the level of moisture is an important cause of mold of plywood, moisture is too high will not only lead to mold of plywood, more easily lead to plywood opening, directly affect the structural strength of plywood finished products. In the production of plywood, the main factors affecting the moisture content of the finished product are: the humidity of the veneer, the moisture content of the glue, the preheating time, the hot pressing time, and the pressure holding time.
3, the existence of oxygen is also one of the causes of mold and discoloration of plywood, but oxygen is everywhere, and it is basically unlikely to be isolated from plywood.
Second, how does plywood prevent mold
1, under normal circumstances, you can add glue anti-mildew agent in the adhesive glue, you can completely prevent the product from mildew, it is mainly used for high starch content of white latex, water-based adhesive. When used together with preservatives, it can enhance the anti-mold effect on the inner surface of the water-based adhesive tank and prevent the mildew after repeated use of the water-based adhesive lid.
2. When storing and using plywood, it is recommended to place it in a ventilated and dry place to prevent the plywood from moldy and gluing problems caused by excessive moisture due to humidity.
3, in view of the problem of mold caused by oxygen, many log manufacturers will take the approach is to sprinkle water or soak logs in water for a long time, the principle is to prevent mildew oxygen separation method, this treatment process is limited to log treatment.
The main reasons for the mold of plywood are that the environmental protection glue in the manufacturing process reaches certain conditions, and the moisture of plywood is too high or long-term contact with oxygen leads to mold. Plywood mildew prevention needs to choose different methods according to different situations
