    The correct selection method of polyurethane foaming machine equipment. There are many types of polyurethane foaming machine equipment on the market. There are countless types of foaming machines of various brands, shapes and names, and new brands and new names of foaming machines. Machines are still being rolled out. Numerous models make the manufacturer dazzled, so that the wrong model is selected. In order to facilitate the correct selection of the foaming machine, the selection method of the foaming machine is now discussed.
    Fully understand the type of foaming machine. Although the basic principle of the foaming machine is to introduce gas into the aqueous solution of the foaming agent, different types of foaming machines introduce gas in different ways. Knowing the type of foaming machine will know its way of bleed air, which will be of great help to further understand its technical characteristics and performance, and help producers to grasp the overall. For example, the low-speed stirring type is to introduce gas by slowly rotating the blades, and the bubble production is small, and the foaming efficiency is low; the high-speed impeller type is to rely on high-speed rotating impellers to induce air, the bubble diameter cannot be controlled, and the foam is uneven; Fast bubble speed, high efficiency, uniform and fine bubbles. Yield, the output is the amount of bubble production, this amount must be slightly higher than 20% of their own bubble volume, to leave room, the bubble production should be based on the verification calculation of the lower limit, not the upper limit. Installed capacity: Installed capacity is the total installed power. This parameter is of great significance for calculating the adaptability of electrical circuits to the total power consumption. Equipment size, this parameter is a necessary factor for overall layout planning of the workshop.

    Bubble diameter range: Generally, it should be compared according to the requirements of specific products for bubble diameter. Carefully understand the quality of foaming. The ultimate product of a foaming machine is foam, and what we need in the production process is also foam. Therefore, the quality of the foam is a criterion for judging the performance of the foaming machine. Judging the foaming quality of the foaming machine should be based on three aspects, namely the foam fineness, foam uniformity, and foam bleeding. Foam density refers to the size of the bubble diameter. The smaller the bubble diameter, the smaller and denser the foam, the better the stability of the foam, the higher the strength of the product produced, and the better the thermal insulation performance. Foam uniformity means that the diameter of the bubble should be uniform. The more uniform the diameter of the bubble, the narrower the distribution range, the more uniform the stress on the product, and the better the use effect. Foam bleeding refers to the amount of foaming agent aqueous solution produced after the foam bursts. The lower the foam bleeding, the lower the foam water content, indicating that the foaming performance of the foaming machine is better.
    The use of polyurethane foaming machine equipment in clothing and sporting goods, polyurethane has changed the style of clothing and plays a role in our lives. Its representative products are comfortable, soft, stretchy and flexible elastic spandex fiber. In addition to being used for puffs, pantyhose, socks for women's makeup, it is also used in ski shirts, swimwear, etc. Its amazing elongation has been used to a great extent. For skiing, yachting and other sports products, polyurethane coatings are selected for their excellent abrasion resistance and weather resistance. Rigid foam with light weight and good abrasion resistance is used as a core material for skis and surfboards. Polyurethane elastomer with excellent elasticity and abrasion resistance is used as the sole of sports shoes.
