Polypropylene (PolyPropylene, PP for short) is a semi-crystalline thermoplastic. It has high impact resistance, strong and tough mechanical properties, and is resistant to various organic solvents and acid and alkali corrosion. It has a wide range of applications in the industry and is one of the common polymer materials. The molecular structure of polypropylene is…
PP pipe has lower hardness and poorer rigidity than metal pipe, so it should be maintained during transfer and construction to prevent mechanical damage caused by improper external force. The orientation of the pipeline should be marked after dark application to avoid damage to the pipeline by the secondary decoration. PP pipe has a certain…
The commonly used socket welding method for PP pipe welding sleeve is to use sandpaper to wipe off the surface of the joint between the pipe or pipe components. If there is a problem with grease on the surface, wipe with vinyl chloride or acetone, insert both sides into the welding sleeve, and insert the…
When the factory is making the electroplating tank, in order to prevent the corrosion of acid and alkali and other requirements, the PP material is generally selected, and the thickness ranges from 10-15mm. PP can be simply understood as plastic, but do you understand its chemical composition and physical properties? PP is a semi-crystalline material.…
1.When installing PP pipe, the influence of ambient temperature on the quality of the device should be considered. Generally, when the temperature is higher than 40°C or lower than 0°C, the installation should not be constructed. 2.Due to the large expansion coefficient of the PP pipeline, thermal compensation should be considered during installation, generally based…
When the pp square pipe is installed, if the operating space is too small, the electrofusion connection method should be used. When the pp square pipe is connected by hot-melt socket, the heating temperature should not be too high, and the temperature should be controlled at about 210 °C, otherwise there will be too much…
PP pipes are widely used in chemical industry, environmental protection, food hygiene, construction water supply and drainage and other fields. PP pipes can transport various corrosive media below 90 degrees Celsius, and their rigidity and compressive strength are superior to traditional plastic pipes. Since the composition of the pp pipe is produced by using the glass…
Air pollution will also damage people’s health. The installation of PP air ducts has an important effect on air pollution. For example, offices and some public buildings will directly install PP air ducts. Then, before installing the PP air duct, it should actually be planned according to the detailed structure of the building. PP air…
In the process of using the pp pipe, if you are not careful, it will be flattened, and then the pipe will not be used normally. Therefore, in order to ensure the use of the pipe, how should we deal with the compressed pipe and how to eliminate this phenomenon. Under normal circumstances, after the…
polypropylene (PP) plastic is carried out after the nylon and excellent resin types, it is a kind of high density, no side chain, linear polymers, high crystallization will have good generalization function. Not when color with a white translucent, waxy; Lighter than polyethylene. Transparency also relatively good polyethylene, polyethylene hardened.PP plastic concept: the proportion of…
