Abstract:
1. A process for producing wood-grained glass magnesium siding, including two procedures of manufacturing wood-grained templates and manufacturing wood-grained glass magnesium boards, wherein the procedure of manufacturing wood-grained templates includes: (1) capturing wood grain patterns on the surface of a natural wood panel with a digital camera or generating various wood grain patterns with a computer, and manufacturing a film of wood grain patterns which has the same dimension as the glass magnesium siding to be produced according to the wood grain patterns; (2) manufacturing a roller, with the wood grain patterns in the film copied onto the roller using photographic projection method, and eroding the roller with a corrosive electrolyte to remove the unwanted portion and remain the wood grain patterns; (3) treating the roller with hard chromium plating such that the hardness of the roller surface reaches an acceptable hardness to roll the templates; (4) installing the roller to a device for rolling the templates, so as to produce templates of various materials according to the materials required; (5) checking the produced templates to determine whether the wood grain patterns conform to those desired for the glass magnesium siding and to select qualified templates for use in the future; and wherein the procedure of manufacturing wood-grained glass magnesium siding includes: (1) preparing MgCl (2) mixing and agitating to prepare cement paste and cement material respectively, wherein cement paste is prepared by agitating the prepared MgCl (3) feeding the templates, wherein the wood-grained templates on which a release agent has been sprayed are fed into a flow production line, on which each of the wood-grained templates contacts with the adjacent one end to end; (4) scraping the cement paste, wherein a first layer of cement paste is scraped on the wood-grained templates, followed by overlaying a layer of glass fiber fabric, and then scraping a second layer of cement paste on the layer of glass fiber fabric; (5) supplying the cement material, wherein a layer of cement material is overlaid on the second layer of cement paste scraped in step (4), and then one or more layers of glass fiber fabric are overlaid on the layer of cement material, and finally one or more layers of non-woven fabric are overlaid on the layer of glass fiber fabric; (6) rolling, wherein the templates which have been supplied with the cement material are rolled into shape via the roller; (7) disconnecting, wherein the shaped boards are disconnected along the joint between two adjacent wood-grained templates; (8) mounting on brackets, wherein the disconnected boards are mounted on brackets and are pruned by scraping off fine wrinkles on the board surface and cement paste and cement material dropped from two ends by a scraper; (9) curing, wherein the pruned boards are transported into a curing area to be solidified into shape and demoulded; (10) soaking and drying to drive brine off, wherein the cured boards are placed into a brine-removing pool and clear water is added into the pool to soak the boards for 8 to 15 hours, followed by swabbing-off the waste water; after clear water is added again for soaking for 8 to 15 hours, the boards are lifted to be placed in a shining ground for drying; (11) cutting, wherein the dried boards are cut according to desired dimensions; (12) spraying with protective priming paint, wherein after the cut boards are cleaned to remove dust, protective priming paint is sprayed on the bottom of boards, and after staying at an environmental temperature between 10° C. and 35° C. for 2 to 6 hours, the finished products can be packaged after final examination.
