矿用管的性能介绍编辑1、 卓越的冲击性能，更适合煤矿井下的恶劣环境：
抗冲击性居塑料之首，无论是外力强冲击，还是内部压力波动，都难以使其开裂。其冲击强度是尼龙66的10倍，聚氯乙烯的20倍，聚四氟乙烯的8倍;比普通聚乙烯冲击强度高4倍，特别是在低温环境，其冲击强度反而达到最高值，其柔韧性能为输送系统提供了极为安全可靠的保障。
与其它材料冲击性能比较表
材料 | UHMWPE | HDPE | PA66 | PC | ABS |
冲击强度kJ/m² | 130 | 37 | 8 | 80 | 15 |
2、 耐磨性：
在目前所有的工程塑料中UHMW-PE的耐磨性居塑料之冠，最引人注目。分子量越高材料就越耐磨，甚至超过许多金属材料(如碳钢、不锈钢、青铜等)。在强腐蚀和高磨损条件下使用寿命是钢管的4-6倍，是普通聚乙烯的9倍;而且提高输送效率20%。
3、 拉伸性能好：
拉伸强度达到22～28MPa，断裂伸长率400%以上。
4、 耐腐蚀：
UHMWPE的化学稳定性很高，除了某些强氧化性酸在高温下能轻微腐蚀外，其他的酸碱液不易腐蚀、耐老化。
5、 极低的摩擦系数，流体阻力小：
管壁光洁度高、摩擦系数小。
6、 不易结垢：
UHMW-PE表面吸附力非常微弱，抗粘附能力强，因而管材表面与其他材料不易粘附、不易结垢。
7、 连接方便：
可直接在母体上翻边用法兰连接，不用再焊接管件，避免了因管件焊接不好而断裂的现象，能节省管件的费用 普通PE管法兰托连接易掉头
8、 阻燃、抗静电性能稳定：
阻燃、抗静电性能良好，均达到标准要求。
9、 使用寿命长：
井下使用寿命超过20年，经济效益显著。
Shandong Wanji Plastic Co., Ltd.
1.10 are produced by Battenfeld and Cincinnati, German: They can produce caliber 20mm-450mm pipes. Our advanced extrusion equipment not only ensures the full plasticization of raw materials, but also effectively prevents the excessive shear degradation of raw materials in the extrusion process, and fully exerts the performance of the raw materials, far higher than the national standards. It has created good conditions for the smooth construction of the pipe.
2. Imported online automatic measurement system and ultrasonic on-line detection device: Each of the company's PE pipe production line equipment is equipped with Innomax online weight control and wall-thickness measurement system, which truly guarantees the consistency of the wall thickness of the pipe.
3. Italian Baiwang raw material dehumidifying and drying system: the Company uses Italian Baiwang dehumidifying dryer, the best brand in the world, which quickly takes away the moisture from plastic raw materials. Eliminates the creation of air bubbles, enabling the product to achieve ideal mechanical, electrical, dimensional stability and appearance. Dehumidifier dryer air pipes are sealed circulatory system, and equipped with filters, so outside climate, in summer of high ambient humidity can be normal production, effectively prevent the production of defective products, greatly reduce the production of waste, and increase productivity.
4. Company's pipe fittings production: our company has 19 injection-molding equipment, that can produce 20mm-1200mm various pipe fittings. Among them, the largest injection-molding machine in China designed and manufactured by Zhejiang Tairui Machinery Co., Ltd. for our company. The maximum clamping force is 2800T, the maximum injection volume is 120,000 grams, and the injection molding diameter dn800mm is molded once. The quality has reached the international level. The level of the product. At present, the company's production of PE pipe has reached more than 600 kinds, fully complete series of supporting production.
