За какво се използва PU за

In daily life, PU is mainly used in furniture. For example, sofas, mattresses, pillows and other products all rely on high rebound (HR) PU sponges to provide comfortable support. This requires a sponge continuous foaming machine. On this basis, auxiliary configurations such as horizontal automatic continuous foaming machines, cutting Машини, машини за рязане на плоски плочи и машини за рязане на дискове също са необходими за обработка на тази серия от продукти .

On the other hand, in cleaning products, scouring pads not only rely on PU sponge materials, but also require them to have strong water absorption and durability. When making scouring pads, stamping equipment, gluing machines, and composite shaping and packaging machines are usually used. These equipment work together to ensure that the scouring pads meet the standards in terms of bonding strength, shape accuracy, and Ефект на почистване, докато отговаря на изискванията за ефективност на масовото производство .

In short, different characteristics such as softness, hardness, density, and temperature resistance can be obtained by adjusting the formula of PU. Wear resistance, oil resistance, and chemical resistance. Water-based PU or bio-based PU (reducing VOC emissions) can be developed. The wide application of PU is due to its diversity and adaptability of performance, and it has penetrated almost every ъгъл на ежедневието .
