Embodiment Construction

[0009] Describe in detail below in conjunction with accompanying drawing and embodiment:

[0010] Be a kind of circular duct of the present invention among the figure, also can make the duct of other shapes obviously. Including the pipe, the main points are: the pipe wall has three layers, and the inner and outer layers 1 and 3 are antistatic polypropylene layers, that is, the polypropylene material is mixed with conductive carbon fibers with a weight ratio of 1 to 5% and a weight ratio of 2 to 8. % conductive carbon black polypropylene layer; the middle layer 2 is a glass fiber reinforced polypropylene layer, that is, the polypropylene material is mixed with a weight ratio of 25 to 45% glass fiber and an amine weight ratio of 1 to 5 per thousand Polypropylene layer of beta-nucleating agent.

[0011] In order to reduce costs and improve cost performance, the weight ratio of conductive carbon fiber in the antistatic polypropylene layer is 1-2%, and the weight ratio of conducti...

Abstract

The invention relates to a pipeline, in particular to a polypropylene (PP) pipeline, which comprises a pipe. The technical scheme includes that a pipe wall has three layers, an inner layer and an outer layer are antistatic polypropylene layers, namely conductive carbon fiber materials with the weight ratio ranging from 1% to 5% and conducting carbon black with the weight ratio ranging from 2% to 8% are mixed in polypropylene materials to form each polypropylene layer, and an intermediate layer is a glass fiber reinforced polypropylene layer, namely glass fibers with the weight ratio ranging from 25% to 45% and amine beta nucleating agent with the weight ratio ranging from 0.1% to 0.5% are mixed in polypropylene materials to form the glass fiber reinforced polypropylene layer. The polypropylene pipeline has the advantages that the polypropylene pipeline is high in corrosion resistance and physical properties and excellent in antistatic performance, the quality of a product can be guaranteed, maintenance cost of equipment is low, resources can be greatly saved, production cost of the product is greatly lowered, and the polypropylene pipeline is a product with excellent economic and social benefits.

Description

technical field [0001] The invention relates to a pipe, especially a polypropylene (PP) pipe. Background technique [0002] Existing polypropylene (PP) pipes have poor corrosion resistance, low physical properties, and poor antistatic properties. Used in many industries such as pharmaceuticals, chemicals, pesticides, environmental protection, light industry, printing and dyeing, etc., it is easy to be corroded, easily damaged, and easy to affect the quality of products, so the maintenance costs of equipment are high, resource consumption is difficult to ensure product quality, and product production high cost. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide a polypropylene (PP) pipe with corrosion resistance, high physical properties and excellent antistatic properties. [0004] A polypropylene pipe, including a pipe, is characterized in that: the pipe wall has three layers, and the inner and outer layer...
