Problems solved by technology

At present, after processing, C601 granite is only widely used in large parks, squares and other places. Although it occupies a certain market space, because of its dark color and many rust (hemp) spots, the price is low, and there is almost no profit in mining and processing. To meet the needs of the market, it is

Embodiment 1

[0021] White electrolytic operation:

[0022] 1. Material selection: Select G601 granite slabs from the same mine with a length of 1.5 meters, a width of 1 meter and a thickness of 2 cm according to the processed slabs;

[0023] 2. Loading: Install the plate on the planned frame of the trolley and fix it so that it will not loosen;

[0024] 3. Entering the furnace: put the installed G601 granite slabs into the electrolytic furnaces in different temperature zones for electrolysis;

[0025] Electrolysis operation:

[0026] The temperature and time of the electrolytic furnace to change the background color of the G601 granite slab from gray to off-white. First, push it into the first electrolytic furnace with a temperature of 228°C for 3 hours, and then push it into the second electrolytic furnace with a temperature of 288°C. 3 hours, and then promote the third electrolysis furnace with a temperature of 348°C for 3 hours, then advance the fourth electrolysis furnace with a temp...

Embodiment 2

[0029] Light green electrolytic operation:

[0030] 1. Material selection: Select G601 granite slabs from the same mine with a length of 1.5 meters, a width of 1 meter and a thickness of 2 cm according to the processed slabs;

[0031] 2. Loading: Install the plate on the planned frame of the trolley and fix it so that it will not loosen;

[0032] 3. Into the furnace:: put the installed G601 granite slabs into the electrolytic furnaces in different temperature zones for electrolysis;

[0033] Electrolysis operation:

[0034] The electrolysis operation procedure for the background color of G601 granite from gray to light green is: the electrolysis temperature and time for the processed G601 granite plate to change from the original gray to light green. The electrolytic furnace is electrolyzed for 3 hours, followed by the second electrolytic furnace with a temperature of 248°C for 3 hours, and then the third electrolytic furnace with a temperature of 288°C for 3 hours, and the ...

Abstract

The invention discloses a preparation method for changing color of granite after electrolysis, belonging to a processing method of building material products. The invention can effectively improve the defects of dark and grey color, many rusty spots (pocks) and the like of the G601 granite through the electrolysis technology to allow the granite to turn to grey white or light green, so that the problems of granite with high price caused by insufficient output of white ground (white granite) on the market and the like are solved. G601 granite turns to grey white or light green from original grey through the electrolysis technology, so that the effects of beautiful white, green, noble quality and elegance are achieved, which is an invention of human. The test results of national building material industry stone material quality supervision and inspection test center show that the produced slabstone product after electrolysis has change in material quality, and the test results of aging quality test in laboratory show that the slabstone product has stable color, uniform material quality, and no color-return situation after being used.

Description

technical field [0001] The invention relates to a processing method for building material products, in particular to a processing technology for the color (base) of G601 granite after electrolysis from gray to off-white or light green. Background technique [0002] As a commonly used decorative material, granite is widely used in interior and exterior walls, squares, floors and various architectural decorations. Fujian Province produces a large number of C601 granite stone mines, accounting for more than half of the province's stone ore reserves. At present, after processing, C601 granite is only widely used in large parks, squares and other places. Although it occupies a certain market space, because of its dark color and many rust (hemp) spots, the price is low, and there is almost no profit in mining and processing. To meet the needs of the market, it is also unable to enter the decoration market of middle and high-end buildings, such as large airports, subways, stations...
