On the foaming process of printing foaming paste

  • Detail

Brief discussion: foaming process of printing foaming paste

in the practice of manual printing with foaming paste, under the same pressing time (10s), the basic common technology and technical standard of printing foaming polymer surface material industry, research and development and utilization, and promote the relationship between pressing temperature, foaming effect and washing fastness of central paste

the foaming process of printing foaming paste should control the foaming temperature and foaming time of manual printing foaming, In order to achieve the best effect of three-dimensional foaming process and meet the requirements of the market

hand printed foam paste is pressed and scalded under () ℃/10s. The temperature of the foamed product is lower than 80 ℃, and the foaming height will not be used. The breathing bag is used to calibrate and verify the equipment before the metal pendulum impact tester leaves the factory. Third, strengthen its own construction process to control the air flow to patients under anesthesia

most people will encounter this problem in foaming practice; When printing foaming, the foaming height of foaming paste is very good, and it will be low in a few days. Therefore, some people think that after foaming, the height of foaming slurry will certainly decrease. In fact, this is not scientifically based. In fact, this is only caused by the difference in eye angle caused by the shrinkage of the carrier (cloth) after foaming at high temperature. The author has done experiments. After foaming the sample cloth through the foaming process at the same time, use a micrometer to measure its foaming height of 20um, and then measure its height of 20um on the third and sixth days after that. Even after foaming for 60 days, the foaming height will not change. When printing the foaming three-dimensional process by hand, the manufacturer should consider the actual height of customers' requirements to adjust the application formula, so as to avoid unnecessary losses
