pvc-u螺旋缠绕管制作过程及技术要求!

  特别是在注塑成型过程中,早晨容易出现熔融劈裂,需要使用的润滑油由于PVC缠绕管熔体粘度高。因此,在PVC缠绕管的挤出加工中,不宜只使用预留的白蜡、硬脂酸和金属皂润滑系统。PVC缠绕管容易附着在热后处理设备的金属表面(特别是机头和模具)。为了消除这种附着,有必要参与外部润滑剂的配方。
  Especially in the process of injection molding, it is easy to melt and split in the morning. The lubricating oil to be used is due to the high melt viscosity of PVC winding pipe. Therefore, in the extrusion process of PVC winding pipe, it is not suitable to use only the reserved wax, stearic acid and metal soap lubrication system. PVC winding pipe is easy to adhere to the metal surface of heat treatment equipment (especially the head and mold). In order to eliminate this adhesion, it is necessary to participate in the formulation of external lubricants.
  配方中热稳定剂的用量远高于PVC。由于CPVC功率管加工温度高,需要热稳定剂。重要的HFB功率管,只有PE功率管使用预留的三盐,两盐热稳定剂是不合适的,当更幼稚的热稳定剂是一个复合铅系列稳定剂与润滑系统。
  The amount of heat stabilizer in the formula is much higher than that of PVC. Due to the high processing temperature of CPVC power pipe, heat stabilizer is needed. For the important HFB power pipe, only PE power pipe uses the reserved three salt, two salt heat stabilizer is not suitable, when the more immature heat stabilizer is a composite lead series stabilizer and lubrication system.
  在PVC缠绕管挤出成型和注塑成型中,加工辅助PVC动力管对提高塑化质量的影响。此时必须使用加工助剂来提高塑化质量,提高CPVC功率管材料的低温冲击性能和成品电阻。在PVC空心缠绕管的情况下,树脂颗粒间的相互作用差,传热差,易熔裂,塑化质量差。
  In the extrusion and injection molding of PVC winding pipe, the influence of processing auxiliary PVC power pipe on the improvement of plasticizing quality. At this time, processing aids must be used to improve the plasticizing quality, the low-temperature impact performance and the finished product resistance of CPVC power pipe materials. In the case of PVC hollow wound pipe, the interaction between resin particles is poor, heat transfer is poor, fusible crack is easy, and plasticizing quality is poor.
pvc-u螺旋缠绕管
  PVC缠绕管耐化学性:不受污水、废水、化学品的腐蚀,不受土壤中腐烂物质的腐蚀。抗冲击:管壁为“工”字结构,抗冲击,刚性高;空心缠绕管是一种延伸性好、不易断裂的柔性管道。抗老化:管体采用黑色防紫外线配方,抗老化性能优异。
  Chemical resistance of PVC winding pipe: not subject to the corrosion of sewage, waste water and chemicals, and not subject to the corrosion of rotten substances in the soil. Impact resistance: the pipe wall is of I-shaped structure, impact resistance and high rigidity; the hollow wound pipe is a kind of flexible pipe with good extensibility and is not easy to break. Anti aging: the tube is made of black anti UV formula with excellent anti-aging properties.
  重量轻:由于空心管结构,在保持刚度的前提下,节省了原材料。在相同直径下,单位长度的重量为水泥管道重量的1/8。施工方便,不需要大型安装设备,降低了劳动强度,缩短了工期。排水性能好:管道内壁光滑,流体动摩擦小,流速快。选用空心管材,管径比钢筋混凝土管径小1-2级。
  Light weight: due to the hollow tube structure, the raw materials are saved under the premise of maintaining the rigidity. Under the same diameter, the weight per unit length is 1 / 8 of the weight of cement pipeline. Convenient construction, no need for large-scale installation equipment, reduce the labor intensity and shorten the construction period. Good drainage performance: the inner wall of the pipeline is smooth, the fluid dynamic friction is small, and the flow rate is fast. Hollow pipes are selected, and the pipe diameter is 1-2 grade smaller than that of reinforced concrete.
  PVC缠绕管经济性能:原材料价格低廉,施工、管理、维修费用低。管接头:通常采用“电热熔”或“热缩”连接技术。管材与管件熔为一体,保证了连接强度,实现了管道系统的零泄漏。本工程采用“热缩带”连接技术。
  Economic performance of PVC winding pipe: low price of raw materials, low cost of construction, management and maintenance. Pipe joint: usually adopt "electric melting" or "heat shrinking" connection technology. The pipe and the pipe fitting are fused together to ensure the connection strength and realize zero leakage of the pipeline system. The project adopts "heat shrinkable belt" connection technology.
