In the production process of melamine paper, the curing degree will be affected by many conditions, they all play a vital role.
The first condition is the amount of volatile and plastic, the volatile part means the quality of the adhesive on the impregnated paper and the proportion of the original paper, and the glue quantity is the ratio of the quality of the adhesive in the impregnated paper to the quality of the original paper, it is necessary to control them when producing melamine paper. The second condition is oven temperature and wind speed, in which the effect of temperature on the pre curing degree is proportional to the change. The third condition is permeability, if the original paper permeability performance is relatively poor, in the process of drying will produce a large number of plastic bubbles.
If the curing agent caused by the pre-curing through high, it is necessary to reduce the temperature and pressure, while shortening the hot-pressing cycle method to solve. may also be due to impregnation drying temperature caused by pre-curing through high, then to take a lower temperature, increase pressure, extend the time of the method, the aim is to improve the fluidity of the gum liquid in the molten state. For the first stage of a higher degree of curing products, should be taken to reduce the temperature, add a long time treatment, and for the first batch of lower-curing products, should try to improve the temperature, reduce pressure treatment.
There is another condition is the curing time of the glue, in the production of different types of impregnated paper, resin curing time is also very different.
