Analyze the future development trend of plastic steel doors and windows
Color Extrusion Technology - New Orientation of Plastic Window
White has always been the main tone of plastic steel doors and windows, but after several years of development, colored plastic doors and windows have become a new hot spot in the market. Colorful plastic profiles are divided into color coating, color integral, and two-color co-extrusion. Several methods and techniques are used. The first two methods are limited by quality and cost, and development is limited. Two-color co-extrusion is the focus of current research. This method is the extrusion of two different colors of the same species or different materials into a whole, forming a co-extruded PM-MA-PVC, ASA-PVC and PVC-PVC many methods, promising for the enterprise and the market.
According to the manufacturer, ASA material can not only resist the degradation, aging, and fading caused by ultraviolet radiation, but also can not cause decomposition or discoloration in the oxidation in the atmosphere and the high temperature in the process. The test results show that the anti-aging performance of ASA is ABS. More than 10 times.
Plastic aluminum composite - a new trend in the industry
At present, plastic aluminum composite technology gradually matures, plastic aluminum composite doors and windows have also been recognized by consumers.
China's plastic doors and windows are a new industry developed after wood, steel and aluminum doors and windows. Due to its many advantages such as environmental protection and energy saving, the development is extremely rapid. However, at the same time as its rapid development, its impact resistance has gradually attracted attention from the industry. . So many manufacturers in the original product, combined with aluminum and other impact materials, developed a steel profile products. After years of efforts, this technology has entered a mature period, and aluminum-plastic door and window products have also begun to enter the market. This kind of compound technology changes the aluminum alloy surface treatment method, carries on the coating treatment to the aluminum alloy exposed surface, has changed the ice feeling of the product, has increased the corrosion resistance ability of the product. The second is that the square tube becomes the inner steel lining mainstream, making such products more resistant to impact. Third, many companies adopt advanced welding technology in the corner assembly to better solve the problem of deformation at the corner assembly.
Energy Saving Technology - New Pursuit of Enterprises
At present, building energy efficiency has attracted the attention of governments at all levels, the housing industry and the design department. Therefore, whether doors and windows are energy-efficient and how energy-saving quality has become a key issue for whether products can occupy the market. In order to seize the market and increase product selling points, various manufacturers have invested a lot of financial resources to carry out energy-saving doors and windows development. This has led to the continuous emergence of energy-saving products. The number of swing doors and windows has soared, accounting for 90% of the total, and the localization of hardware fittings, insulating glass processing equipment and seals for energy-saving doors and windows has been accelerating, promoting the reduction of production costs for energy-saving doors and windows, and increasing market sales. The overall processing speed of doors and windows has been accelerated. A few years ago, the processing of foamed PVC doors and windows was still a blank in China. However, domestically produced products of this type can be extruded once to achieve domestic production. Not only quickly occupied the domestic market, but also exported to more than 40 countries in the world. In a certain exhibition at some time ago, most of the energy-saving products introduced by many manufacturers performed excellent energy-saving quality. A new product that passed Japanese JIS certification and Korea's high-efficiency energy-saving materials could save 60 percent due to advanced energy-saving technologies. % of heating costs. The manufacturer also introduced a three-glass, three-cavity, three-stage, sealed, heat-insulated door and window. Its products are also based on the technical indicators of airtightness class I, watertight class I, and wind pressure class I, and also increase their heat transfer coefficient to K. =1.66W/m2k, the product insulation performance has reached the leading domestic level.
A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe. A blind flange is a plate for covering or closing the end of a pipe. A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together.
Although the word flange generally refers to the actual raised rim or lip of a fitting, many flanged plumbing fittings are themselves known as 'flanges':
There are many different flange standards to be found worldwide. To allow easy functionality and interchangeability, these are designed to have standardised dimensions. Common world standards include ASA/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese/Korean). In the USA, ANSI stopped publishing B16.5 in 1996, and the standard is ASME B16.5
