Embodiment 1

[0022] Because there is a funnel on the top of the existing twin-screw extruder, when processing the pellets, you only need to take the mixed mixture and put it upside down in the funnel, so the overall weight of the mixture is not limited when mixing, just according to the weight The percentage is calculated as 100%. In a mixture of high-purity flake graphite and silane coupling agent, high-purity flake graphite accounts for 99% and silane coupling agent accounts for 1%. Stirring treatment, since most high-speed mixers have temperature control devices, when the early temperature is lower than 80°C, it can not be counted in the stirring time. When the high-purity mixer only needs to stir for three to five minutes, the high-purity flake graphite and silane coupling agent can be evenly stirred. After the mixture of high-purity flake graphite and silane coupling agent is evenly stirred, we are mixing Pour the sulfide into the high mixer for secondary mixing. At the same time, whe...

Abstract

The invention provides a PPS tube anda production method thereof and a machine used in cooperation with the production method. According to the production method of the PPS tube, a mixture of high-purity flake graphite and a silane coupling agent is added in existing polyphenylene sulfide, the fluidity of PPS tube raw materials is low after the PPS tuberaw materials are melted by a single screw extruder, and through the way, the extrusion production of the PPS tube is realized through the cooperation of the single screw extruder with a special mould and a mould temperature machine, so that thelength of the produced PPS tube can be controlled freely. The problem of installation inconvenience and poor sealing due to the fact that the length of an existing injection molding PPS tubeis limited so that flange connection is needed during use is solved, the production and use efficiency is greatly improved, and meanwhile thecost is reduced.

Description

technical field [0001] The invention belongs to the field of PPS pipes, and specifically relates to a PPS pipe, a production method thereof and a machine used in conjunction with the production method. Background technique [0002] PPS pipe has the advantages of high mechanical strength, high temperature resistance, high flame retardancy, strong chemical resistance, etc., and is widely used in chemical pipelines. The material of the PPS pipe is polyphenylene sulfide, its melting point is between 285-300°C, it has strong fluidity after melting, and solidifies after cooling down. Therefore, the production of existing PPS pipes is produced by high-pressure injection molding, and cannot be used. Produced by extruder extrusion. Due to the limited length of injection molds, conventional 1.2-meter and 1.5-meter-long molds are generally used, and PPS pipes of four or five meters or longer cannot be produced. Therefore, when longer pipes are required in industrial applications, they...
