The key plastic pipe material of the P duct is polypropylene, which is a thermoplastic resin made from propylene polymer. Non-toxic, odorless, odorless milky white high-crystalline polymer, the relative density can only be the net weight of other materials is not as light as it is. It is worth mentioning that its organic The chemical reliability is very good. In addition to being corroded by concentrated sulfuric acid and concentrated nitric acid, it is stable to various other chemicals, but the low content of aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can make polypropylene soft and swell.
At the same time, its organic chemical reliability also gradually increases with the increase in grain size, so polypropylene is suitable for making various chemical pipelines and parts, and the actual effect of corrosion resistance is excellent. The pp air pipe is suitable for the extraction of corrosive vapors, The actual manufacturing industries include electroplating process industry, industry, machinery industry and can make pipes.
PP air pipe production and equipment commonly used plates, pipes and other key handicraft materials should be in line with the design concept and related national standards Standards, and apply the original factory inspection to confirm that the materials must be launched in accordance with the relevant standards of the current national standards. PP air pipes have heat resistance, convenient pipeline connection heat fusion, electrofusion, pipe connection, recycling applications.
Characteristics, the key is used in field hanging water system software, house building water supply and drainage system software, heating system and its chemical piping system software, etc., also has the following characteristics: excellent environmental hygiene characteristics, high temperature resistance, thermal insulation, environmental protection and energy saving, easy installation 1. Reliable connection, application of raw material recycling, simple machine equipment regulations, simple production process flow, easy to manipulate, and free piping layout.
