The polyurethane foaming process demands high standards for wear resistance, chemical corrosion resistance, and temperature adaptability of mixing containers. Yishui Xinsen Stainless Steel Products Co., Ltd. has independently developed and produced a series of foaming buckets to address the pain points of the foaming industry. These buckets, made of stainless steel and featuring special inner wall treatment and mixing accessory design, significantly enhance the mixing uniformity of foaming raw materials and improve cleaning convenience, making them an important partner for foaming equipment manufacturers.
Yishui Xinsen foam buckets are primarily used in polyurethane high-pressure foam machines, low-pressure foam machines, and experimental foam equipment for storing isocyanate (black material) and polyether polyol (white material). The barrel body is made of thickened stainless steel plate, formed through a combination of argon arc welding and double-blade welding processes, resulting in high weld strength and no porosity. The inner wall can be treated with mirror polishing or Teflon coating, significantly reducing material adhesion and shortening the cleaning time for color and material changes. Given the temperature sensitivity of foam materials, the company has developed foam buckets that can be equipped with water jackets or electric heating belts to achieve precise temperature control (±1℃), ensuring stable foam reaction activity.
In terms of safety design, the foam barrel is equipped with an explosion-proof pressure relief valve, a nitrogen protection interface, and an anti-static grounding device as standard, effectively preventing safety accidents caused by abnormal pressure or static electricity accumulation. The barrel lid adopts either quick-opening clamps or bolted flanges, and the sealing ring is made of solvent-resistant fluororubber, which can withstand the erosion of cleaning solvents such as acetone and DMF for a long time. The discharge port can be equipped with a ball valve, needle valve, or pneumatic angle seat valve according to customer needs, adapting to different flow control accuracies.
"In the past, the inner walls of the foam buckets would become heavily scaled after prolonged use, and it would take half a day to clean them. However, after using Xin Sen's foam buckets, the mirror-polished inner walls become clean at a single wipe, and our production efficiency has increased by over 30%," reported the person in charge of a certain automobile seat foam production line.
Yishui Xinsen, with its comprehensive marketing service network, can provide customers with one-stop services ranging from model selection consultation, drawing confirmation, sample barrel testing to bulk supply, and after-sales maintenance. Adhering to the principle of "pragmatic development and quality service", the company continues to delve deeply into the field of foam barrels, striving to become the preferred choice for supporting containers in domestic foam equipment.
