TH6209C3 - Double-sided patterned building material And the production process of such building materials - Google Patents

Abstract

DC60 This invention involves a fiber cement construction material with a pattern on both sides. And the process of producing such materials by rolling or pressing by rollers on wet tiles, the process of manufacturing building materials is improved by installing additional equipment. Especially the roller For making the pattern above And the bottom of the production line Including having a control system for the rolling action Both by drive gear and motor to be able to produce building materials with pattern on both sides simultaneously, reducing the step in the manufacturing process. Also able to modify various patterns by Replacing the top-mounted pattern roller And the bottom of the production line This invention deals with a fiber cement building material with a pattern on both sides. And the process of producing such materials by rolling or pressing by rollers on wet tiles, with process improvements in building materials production by installing additional equipment. Especially the roller For making the pattern above And the bottom of the production line Including having a control system for the rolling action Both by drive gear and motor to be able to produce building materials with pattern on both sides simultaneously, reducing the step in the manufacturing process.

Claims (3)

1.Process for the manufacture of fiber cement pre-formed materials with a double-sided pattern by Wet ironing method or wet press which consists of the following steps. The preparation of the fiber cement slurry to the specified density to feed the resulting mixture into the vat (14) for wet separation. The water is separated by rotating a cylindrical screen (16) that is positioned horizontally. Through the fiber cement slurry in the wax tank (14), the separated wet ingredients accumulate on the outside of the cylindrical sieve (16) and excess water is removed. Rotate the belt (12) to make contact with the horizontally placed cylindrical screen (16) where the wet mixture is deposited. Wet the mixture on a cylindrical screen (16). Each ball adheres to the rotating belt. The pressing roller (18) allows the wet ingredients to adhere to the belt. As the belt (12) runs through the cylindrical sieve (16) increases, a thicker layer will accumulate on the belt (12). Water is extracted. From the wet ingredients by the belt (12) conveying the wet mixes through the vacuum box Wetting of wet ingredients into tiles By forming rollers (20) where one layer of the mixture Wet is equal to one rotation of the forming roller (20), and then cut the wet tile from Forming roller) (20) with blades inside forming roller (20) wet press, fiber cement tile. By a wet press roller that is driven by a motor The bottom of the roller is installed to support the pressing of the wet roller, which is unique in the wet pressing process for patterning on tiles. Fiber cement The wet sheet tiles are conveyed to a pattern roller consisting of two rollers, the top roller (22) and the bottom roller (24), that perform the pattern on the surface. Wet sheet tiles Where the top roller (22) will rotate clockwise. While the bottom rollers (24) rotate counterclockwise, with gear (26) driving the two rollers. And control the speed Rotate the rollers (22, 24) with a motor (28). 2.Process for the production of double-sided patterned fiber cement building materials According to claim 1, the moisture content of the wet tiles in the manufacturing process is 20 to 40 percent. 3.Process for the production of fiber cement construction materials with a double-sided pattern in accordance with either one or two of the claims. Where the pattern displayed on the fiber cement board has a depth from 0.8 to 2 mm.
