New co-extruded PVC Micro-foaming steel plastic window and door profiles

National patent. The results of the successful completion of the steel-plastic co-extruded PVC profile production line of micro-foam design, manufacture, formulation, process research and window assembly molding technology research and development. Steel-plastic co-extruded window profiles because of its appearance resembles a high-level timber, rigid, and windows and doors assembly process is simple, so this profile will be more and more people know, only l0 or so domestic manufacturing enterprises and 100 profiles Steel-plastic doors and windows more than co-extruded assembly plant, most of the round window and door profile extrusion mouth won Academy, Shandong, Heilongjiang, Hebei,[link widoczny dla zalogowanych], Shanxi, Beijing and other provinces and cities, mostly in the 0.3 scale profiles of a lt / year and 50,000 mz doors and windows / year, which Beijing Co., Ltd. all windows and doors profile annual production capacity of 1.5 million t, doors and windows 1O0 million m. . Second, the characteristics of a steel-plastic co-extruded profiles,[link widoczny dla zalogowanych], PVC foam formulations used to replace the current general rigid PVC formulations, reducing the proportion of plastic parts, thus reducing the amount of raw materials; 2, the use of skin foam technology to ensure the surface profile hardness quality; 3, lined with plastic and new technology co-extruded composite technology to achieve integration of plastic and steel liner; 4, finishing with 0.8-1.2mm galvanized steel, and rolling through the precise form the whole face closed a variety of shaped steel liner to ensure the accuracy of profile stiffness and lumen; 5 days of burning wood with imitation color profiles, comfortable and elegant appearance, improve the texture quality windows and doors; 6, factory assembled windows and doors can also may assemble, adaptable, easy to install. Third,[link widoczny dla zalogowanych], steel production technology co-extruded profiles co-extruded profiles steel plastic main raw material for PVC resin, cold-rolled galvanized steel sheet and plate glass. Coextrusion process in three steps: rolling steel lining, raw materials and steel plastic co-extrusion blend. Lined ~ LSL] and material blending for the former procedure, after completion of co-extruded, after rolling through the liner will be sent by the extruder stage, the tractor pulling, continuous through the extruder. Lined by heating, fine-tuning into the second-rate channel mold, PVC mixture evenly from the nose into the extruder feed tank, after the heated plastics attached to the liner surface, followed by [link widoczny dla zalogowanych] plasindustry. com Group \Wedelia machines use a single extrusion. The process flow diagram is as follows: PVC resin and additives on a material ingredient of a mixture of a] l of a slight bow of a galvanized steel sheet for a clean cut a roll of a feeding _j. . A co-extruded shape of a cooling phase _LL1LL final packaging and storage by a total of 4.1 out of doors and windows of the corner connection steel-plastic co-extruded corner doors and windows most of the windows and doors by connecting with existing welding machine welding methods, it is a Core inserted into the two special right-angle corner sections to be connected the ends of the cavity lined with screws and angular profiles to achieve the Core fused connection, and then sealed with special sealing materials. This form high strength,[link widoczny dla zalogowanych], strong wind pressure, the overall rigid, not easily deformed and difficult to droop, and the group angle than the traditional plastic door and window technology is simple, time-saving, easy to operate. Connection shown in Figure 1: Figure 1 profiles the connection window in the club's connections in the 4.2 club connection is required in the club expected size using special cutting saws cut straight material (90.), Then in the club with special End milling the required shape and size of processing the step face, so that the ends overlap with the corresponding frame materials, special steel, then screw the connector in the club through the material and frame material together. 4.3 The problem of thermal expansion and contraction of the steel and plastic not the same coefficient of thermal expansion, therefore, to address the thermal expansion and contraction effects of the impact on the corner, corner in the group before milling with a drill head at the end of the steel liner profile milling to the part to the expansion of space to be lined to avoid the two-liner in the group phase after the top corner, when in use to avoid corner cracking unglued. 4.4 corner seal corner seal to ensure, in advance of the group angle at both ends of the profile surface treatment with a special sealant, and then Chajiao core board. Fifth, to the skin micro-performance PVC co-extruded profiles steel plastic foam is a new product, there is no national standards and industry standards. According to the light of the French DIN53 \shown in Table 1 (40 casement window frame for example). The main technical performance windows and doors (hollow DT) Table 2.
