What are the effects of excessive addition of calcium powder?

● Increased brittleness: Calcium powder is an inorganic filler. Although it can enhance the rigidity and hardness of pipes, excessive addition will weaken the toughness of pipes, make them more brittle, reduce impact resistance, and easily cause brittle cracking when exposed to external force or low temperature.
● Decreased tensile strength: PVC resin gives the pipe a certain elasticity and tensile strength. Excessive calcium powder will reduce the ductility and tensile strength of the pipe, making the pipe more likely to break or deform during installation or use.
● Decreased surface smoothness Adding excessive calcium powder will affect the surface quality of the pipe, causing the surface to be rough or granular, which not only affects the appearance, but also affects the fluidity of the fluid in the pipe and increases friction resistance.
● The weight increases and the installation costs increase. When the calcium powder content increases, the density of PVC pipes will increase significantly, resulting in an increase in the weight of the pipes and increased transportation and installation costs, especially for large-diameter pipes.
Therefore, when specifically selecting PVC pipes, try to choose low-calcium ones. The higher the calcium powder content, the worse the quality. Of course, people are more pursuing cost-effectiveness and need to find a balance between quality and price. Some people joked that they can already make 600 parts of calcium tubes, but the “packaging and unloading” are not included in the loading, which makes people dumbfounded.
