At present, in the production process of prefabricated PHC pipe piles, the "clamping post-placement fabric technology" is commonly used. This process requires 4 to 6 people to carry out the process of smoothing and cleaning the concrete at the top and bottom molds. The labor intensity is large and the production efficiency is low, which seriously restricts the production capacity of the prefabricated pipe piles and soil. At the same time, there are lax mold seals and pipe molds. Deformation risk.
In order to solve the technical problems in the industry, Zoomlion set up a technical research team composed of experts from the National Concrete Machinery Engineering Technology Research Center and the Research Institute of Concrete Machinery Co., Ltd., with the cooperation of the production, materials and other departments, from the scene data collection to the product Assembly off the assembly line, all members work overtime to complete the HBT80 · 14 · 132SG pile pump development.
It is reported that the HBT80·14·132SG pile pump has inherited the original superior performance of the Zoomlion pump, but also has many new features. It has independent intellectual property rights of the negative inclined pumping unit, which improves the suction efficiency of the C80 high-viscosity concrete. The double-drive stirring system increases the stirring torque and makes the stirring shaft more even and reasonable, ensuring the concrete in the Uniform flow in the hopper improves suction performance; new distribution buffer patented technology improves the service life of the swing cylinder and S-tube; new wear-resistant materials and welding process improve the wearing parts such as eyeglass plate, cutting ring and S-tube. The service life of the new type of stirring seal structure improves the service life of the stirring seal.
Polyurethane System For Shoe Sole
1. Polyester system for safety shoes, single and double density
2. Polyester system for casual shoes, sports shoes
3. Polyester system for lady's high heel shoes, low density and high hardness
4. Polyether for insole/outsole
A Pu system for shoe soles refers to the use of polyurethane (PU) material in the manufacturing of shoe soles. PU is a versatile and durable material that offers several advantages for shoe soles.
Here are some key features and benefits of using a PU system for shoe soles:
1. Cushioning: PU provides excellent cushioning and shock absorption properties, making it ideal for footwear that requires high levels of comfort and impact protection.
2. Lightweight: PU is a lightweight material, which helps reduce the overall weight of the shoe, making it more comfortable to wear and reducing fatigue during extended use.
3. Flexibility: PU offers good flexibility, allowing the shoe sole to bend and flex with the natural movement of the foot. This enhances comfort and prevents stiffness or discomfort during walking or running.
4. Durability: PU is highly durable and resistant to wear and tear, making it suitable for long-lasting shoe soles. It can withstand repeated use and exposure to various environmental conditions without losing its structural integrity.
5. Slip resistance: PU can be formulated with specific additives to enhance its slip resistance properties, providing better traction and grip on different surfaces. This is especially important for safety footwear or shoes used in slippery conditions.
6. Design versatility: PU can be molded into various shapes and designs, allowing for greater design flexibility and customization options for shoe soles. This enables manufacturers to create unique and visually appealing footwear.
7. Water resistance: PU can be made water-resistant or waterproof, which helps protect the shoe sole and the foot from moisture, rain, or other wet conditions.
Overall, a PU system for shoe soles offers a combination of comfort, durability, flexibility, and design versatility, making it a popular choice for footwear manufacturers and consumers alike.
