Advantages of plastic standard parts

The production of pipes is typically done in batches. However, due to the high cost of introducing advanced production lines and technologies, some domestic enterprises and academic institutions have started researching PP-R pipe forming equipment and production techniques, achieving significant progress. The Institute of Plastics Engineering Technology at Qingdao Institute of Chemical Technology has leveraged its expertise in process design, structural engineering, and mechatronics to develop a successful co-extrusion production system for PP-R pipes. This equipment can produce 16 different types of pipes with diameters up to 75 mm. On February 27, 2000, it successfully passed an appraisal organized by the Shandong Provincial Science and Technology Commission and developed the technology for manufacturing PP-R pipe fittings. Thanks to its excellent overall performance, PP-R pipes are expected to have wide applications in various fields. Currently, relevant government departments and local authorities have issued policies to gradually phase out galvanized and cast iron pipes within a set timeframe, while promoting the use of plastic pipes like PP-R. This creates a favorable policy environment for the widespread adoption of PP-R pipes. The Shanghai Engineering Construction Standardization Office has established technical regulations and application standards for PP-R piping systems used in building water supply. With the localization of PP-R raw materials and molding technologies, it is expected to drive the upgrading of China’s construction materials industry. In addition to pipes, other plastic products are also gaining attention. For example, plastic bolts and nuts made from glass fiber-reinforced epoxy resin have appeared on the Japanese market. These components are manufactured using hydraulic presses under high temperature and pressure, offering high fracture and fatigue strength while weighing only a quarter of their metal counterparts. Plastic nails, on the other hand, are resistant to magnetism, rust-proof, and easy to install. They can be used on both cork and hardwood surfaces, making them a versatile alternative to traditional metal fasteners.

Kitchen Mixer

Kitchen faucets can be divided into many types according to their function and material. According to the function, the kitchen faucet can be divided into single cold faucet, double cold water faucet and mixed faucet. The single-cooled faucet only provides cold water, suitable for use scenarios that do not require hot water. Double cold water taps provide hot and cold water, respectively supplied by two separate water pipes, so that users can adjust the water temperature according to their needs. The mixing faucet combines the hot and cold water pipes, and adjusts the water temperature and water flow intensity through a knob or pole, which is more convenient and practical.

According to the material, the kitchen faucet can be divided into stainless steel faucet, copper faucet and plastic faucet. Stainless steel faucets are corrosion-resistant, easy to clean and durable, and are suitable for kitchen environments that are used for a long time. The copper faucet has good thermal conductivity and antibacterial properties, but also has a certain decorative, suitable for users who pay attention to the overall style of the kitchen. Plastic faucets are light and easy to install, suitable for temporary or economically demanding kitchens.

In addition, there are some special types of kitchen faucets, such as retractable faucets, filter faucets and spray faucets. The retractable faucet can be freely expanded and retractable as needed for easy cleaning and use. The filter faucet has a built-in filter element, which can filter impurities and odors in the water to provide a more pure water source. The spray faucet has a variety of spray modes, which can adjust the water flow form according to needs, such as spray, atomization, etc., to provide a more comfortable experience.

To sum up, kitchen faucets can meet the needs and preferences of different users according to their functions and materials. Choosing the right kitchen faucet can improve the convenience and decorative effect of the kitchen.
