Polyvinyl chloride conduit is a pipe used to protect and hide wires and cables in power lines. It not only enhances electrical safety but also provides a path for wires. Polyvinyl chloride conduit has many advantages, including anti-corrosion, anti-leakage, and easy threading. It is suitable for normal indoor environments and places with high temperature, dust, vibration, and fire hazards, but not suitable for use in places with particularly humidity, acid, alkali, salt, and explosion hazards.
Polyvinyl chloride conduit density standard
The density standard of Polyvinyl chloride conduit is usually between 1.35 and 1.46 g/cm3. This density range is applicable to PVC Pipes for Water, which should be between 1350 and 1460 kg/m3 according to GB/T 10002.1-2006 standard.
For polyvinyl chloride (PVC) sheath materials for wires and cables, its density also has clear standards. The density of polyvinyl chloride used in flexible cables is roughly between 1.36 and 1.39 g/cm3, while the density of soft PVC used in national standards is roughly around 1.35 to 1.40.
In addition, the density of polyvinyl chloride conduit materials will also vary depending on their use and product type. For example, the density of hard and transparent PVC is around 1.35 g/cm3, and the density of hard but opaque PVC is between 1.4 and 1.8 g/cm3, or even higher.
Function
The main function of polyvinyl chloride conduit is to protect wires and cables. It has the characteristics of light weight, insulation, flame retardant, durability, and corrosion resistance, and is widely used in indoor construction and residential electrical wiring projects.
Advantages and characteristics
1. Good insulation performance: Polyvinyl chloride conduit is an electrical insulator with excellent insulation performance. It can effectively prevent leakage of wires and ensure the safety of wire operation.
2. Strong corrosion resistance: Polyvinyl chloride material has excellent corrosion resistance and can resist the erosion of various chemical substances, especially in a highly corrosive environment.
3. Good flame retardant performance: It has good flame retardant performance and is not easy to burn. Even if it encounters a fire source, it can prevent the spread of fire to a certain extent, providing additional safety protection for wires.
4. Convenient construction: Polyvinyl chloride conduit is light and easy to bend, which is convenient for construction and installation. During the construction process, the shape and length of the pipeline can be flexibly adjusted according to actual needs, which greatly improves the construction efficiency.
5. Affordable price: Compared with other wire protection materials, the price of polyvinyl chloride conduit is relatively low, which makes it more attractive in market competition and has become the preferred product for many engineering projects.
6. Good environmental performance: The pipe is an environmentally friendly material that can be biodegraded and will not pollute the environment. In addition, it does not produce any harmful substances during use and is harmless to the human body.
Is Polyvinyl chloride conduit toxic?
Polyvinyl chloride conduit itself is non-toxic, but it may become toxic under certain conditions. Polyvinyl chloride (PVC) is a widely used plastic material that is often used to make a variety of products, including catheters. Pure PVC materials generally do not contain any toxicity and will not cause harm to the human body. However, the characteristics of PVC materials themselves are somewhat insufficient, so a large number of additives need to be added to improve their heat resistance, toughness and ductility. These additives may produce some toxic chemical reaction substances when they react with PVC materials, which may affect the health of the kidneys and liver.
Under the condition of standardized use of materials and dosages such as stabilizers and plasticizers, PVC is also non-toxic when used for food packaging. However, if toxic and harmful additives are added during the production process or toxic impurities and waste materials are mixed, and the hygiene and safety requirements are not followed, toxic substances may be precipitated during use due to oil, high temperature, etc., which may endanger human health. Therefore, it is very important to choose polyvinyl chloride conduits produced by regular manufacturers.
