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 coextrusion. There are several production methods and technical processes. 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, for the enterprise and the market is optimistic.

Industry sources pointed out that ASA material not only resists degradation, aging, and fading caused by ultraviolet radiation, but also does not cause decomposition or discoloration due to oxidation in the atmosphere and high temperature during processing. Test results show that the aging resistance of ASA is ABS. More than 10 times.

Plastic aluminum compound - 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. Because of 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 the attention of 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 processing to the aluminum alloy exposed surface, has changed the product cold feeling, has increased the product corrosion resistance. 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

It is understood that at the moment, building energy efficiency has caused the attention of governments at all levels, the housing industry and the design department. Therefore, whether the energy saving of doors and windows and the quality of energy conservation have become the key issues for whether the products can occupy the market. In order to seize the market and increase product selling points, various manufacturers have invested a lot of financial manpower to develop energy-saving doors and windows. 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, and the production cost of energy-saving doors and windows has been reduced, and the market sales have increased. The overall processing speed of doors and windows has been accelerated. A few years ago, the processing of foamed PVC doors and windows in China was still a blank, and domestically produced products of this type can now 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-insulating 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, so that the product thermal insulation performance has reached the leading domestic level.
