Abstract

The invention discloses a manufacturing technology of a pressing color-change pipe and belongs to the technical field of pipe processing. The pressing color-change pipe comprises a high-molecular polymer, sebacic acid, high-density polyethylene, methyl cellulose, triphenyl phosphite, a halogen flame retardant, zinc stearate, wollastonite and phthalate. By adding the triphenyl phosphite and the halogen flame retardant, the flame retardancy and oxygen resistance of the pipe are enhanced, and the pipe has light stability. At the time of mixing, the raw materials are bonded through the methyl cellulose. Meanwhile, at the time of mixing, zinc stearate is added for lubricating a preliminary molding die, discharging is facilitated, the high-density polyethylene is added in the manufacturing technology of the pipe, thus the pipe has certain cold resistance, cracking of the pipe at a relatively lower temperature is avoided, and a small amount of wollastonite is added to make the pipe applicableto different temperature situations.

Description

technical field [0001] The invention relates to the technical field of pipe processing, in particular to a manufacturing process for pressure-changing pipes. Background technique [0002] Pipelines are widely used in many industries and fields, mainly used in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] With the continuous and stable high-speed growth of my country's national economy, it provides a good macro environment and broad space for the construction of urban infrastructure. Policies and regulations on pollution control and environmental protection. Water supply, water saving, drainage and sewage treatment will become the focus of urban municipal construction in the future, which provides market development space for the promotion and application of plastic pipes. Because structural wall pipes can save raw materials and reduc...
