Common PPR pipes used in residential construction are primarily green and white, but some manufacturers offer a wider range of colors, such as yellow and blue, to attract consumer attention and increase sales.PPR pipeWhat is the production process?
In reality, when producing PPR, a material called "color masterbatch" must be added. Pure PPR raw material particles are colorless. After adding color masterbatch, the PPR pipe will have color. At the same time, the PPR pipe also has light-blocking properties. Since adding color masterbatch can increase the light-blocking properties of the PPR pipe, color masterbatch is essential for the production of PPR pipes.
How important is light transmission for PPR pipes? If the light transmission of PPR pipes is poor, light can penetrate through the pipe wall and illuminate the water, accelerating the growth of algae. Algae will accumulate on the pipe wall over time, eventually forming sludge that affects water quality. Therefore, the light transmission capability of PPR pipes directly affects the water safety and drinking health of subsequent users. National standards also specify this. According to national standards, the light transmission rate of PPR pipes should not exceed 0.2%, which essentially means that the pipes are opaque.
So, the question arises,PPR pipeThe different colors may indicate differences in the light-blocking properties of PPR pipes. Does the white pipe have the worst light-blocking properties? Generally, the light-blocking performance of white PPR pipes is relatively weak in the market. Therefore, the statement that white pipes have definitely poor light-blocking properties is inaccurate. We have conducted experiments to show that even PPR pipes with the same color have different light-blocking properties.
Therefore, we can conclude that the color of PPR pipes may have some influence on their light-blocking properties, but this influence is not absolute. It is not feasible to determine the light-blocking performance of pipe materials solely based on color. Experimental verification is necessary. In fact, the light-blocking performance of PPR pipes is primarily related to the color coverage of the color masterbatch used.
Another important consideration is that PPR pipes manufactured from recycled materials also exhibit enhanced opacity. Some unscrupulous companies in the residential construction market may use this to their advantage byPPR pipeDuring manufacturing, recycled materials, waste materials, and scrap are incorporated, followed by color matching to mask the inherent low-quality of the raw materials. Therefore, a pipe with good light-blocking properties is not necessarily of high quality. To accurately differentiate the quality of PPR pipes, it is essential to consider multiple factors, including the materials used, the manufacturing process, and production standards, rather than relying solely on one aspect.
