1. UPVC pipe means stearyl polyvinyl chloride, with good quality, which is suitable for industrial sewage, food-grade ultra-pure water, reverse osmosis and other water treatment equipment, plating equipment, etc., and has a wide range of applications. PVC pipe means polyvinyl chloride. Generally, it has poor quality, insufficient hardness, easy aging, etc. It is used for drainage pipes.
2. U in UPVC, whose original text is unplasticized, is called UPVC or PVCU when PVC raw materials are made without plasticizer. Without plasticizer, all chlorine in PVC raw materials will be volatilized, while many residual chlorine in PVC raw materials with plasticizer cannot be volatilized.
3. UPVC is a product that improves the performance on the basis of PVC. There is no residual chlorine released from the water pipes of UPVC, but there will be residual chlorine released from the water pipes of PVC.
The difference between PVC pipe and UPVC pipeThere are significant differences between PVC pipes and UPVC pipes in many aspects.
First of all, from the material point of view, PVC pipes belong to PVC pipes, while UPVC pipes belong to hard PVC pipes. This difference makes UPVC pipe superior to PVC pipe in corrosion resistance, and UPVC pipe is also lighter than PVC pipe.
However, PVC pipes are better in aging resistance and impact resistance.Secondly, their uses are different. UPVC pipes are mainly used in industrial and building sewage pipes, especially in industrial sewage, food-grade ultra-pure water, reverse osmosis and other water treatment equipment, as well as plating equipment and other fields. And PVC pipes are more used for household sewage pipes, such as drainage pipes.
Thirdly, from the price point of view, PVC pipes are usually more expensive than UPVC pipes. This is mainly because the production technology and material cost of PVC pipes are high, and the construction methods of them are also different. The installation of PVC pipes is relatively simple, mainly by socket connection. However, the installation of UPVC pipe is relatively complicated, and glue is needed to connect and fix it.
It is worth noting that the "U" in UPVC stands for unplasticized, which means that no plasticizer is added in the manufacturing process. This makes all the chlorine in PVC raw materials volatilize during the manufacturing process of UPVC pipes, thus avoiding the release of residual chlorine.
However, due to the addition of plasticizer to PVC pipes, residual chlorine may be released from their water pipes during use.Generally speaking, there are differences between PVC pipe and UPVC pipe in many aspects, such as material, performance, use, price and construction method. In the process of practical application, the suitable pipe should be selected according to the specific use scenarios and requirements.
As for the question whether it is necessary to make anti-skid strips for stairs, the answer is yes. As an important passage connecting different floors, the safety of stairs is very important. With the passage of time, the surface of stair tread tends to become smooth, especially in places with high traffic, and this smoothness will be more obvious. In addition, weather conditions such as humidity, rain and snow will also aggravate the slipperiness of stair steps, thus increasing the risk of falling and slipping. The installation of anti-slip strips is precisely to effectiv transformation of economic growth mode, if the core technology development ability of enterprises is in a leading position, it will open up new paths for the sustainable development of the entire plastic footwear industry.
