Abstract
A process for metallizing surface of granite includes such steps as cleaning the decorative granite slab, baking and vacuum plating of titanium or titanium nitride for silver or golden colour. Its advantages is beautiful appearance.
Description
The present invention relates to a kind of treatment process of stone material, particularly a kind of process for metallizing surface of granite.
As everyone knows, because various places geologic condition difference, the quality of stone material of formation also has difference, and the natural granite base material crystal that has is thick, and be mingled with the patch of white tape shape, as decorating usefulness, it is a kind of not attractive in appearance, the granite in slab of low value, there is the granite of magnificent color then to have very high use value, for this reason, people attempt granitic surface is handled, in the hope of obtaining high-grade grantie decoration plate material.At present polishing is adopted in granitic surface treatment usually, painted processing, also promptly adopt section, polish with the silicon carbide bistrique grinding, adding the pigment identical with the granite true qualities when grinding and polishing together grinds, handling the grantie decoration plate material color that obtains in this way can be more bright-coloured than original base material color, but the color that this increase is got on is not lasting, not corrosion-resistant, and this method can not make the granite in slab surface present the unexistent gold of natural granite, silver color, more impossiblely makes it reflect metalluster.
The object of the present invention is to provide a kind of process for metallizing surface of granite that can change the surface of granite color.
Can plate the metal level of gold or silver color at surface of granite if the inventor justs think, make its glittering or silver color spot billows in surface, and can improve granitic use value greatly.
The present invention is achieved in that a kind of process for metallizing surface of granite, it is characterized in that: the grantie decoration plate material cleans--oven dry--vacuum titanizing or vacuum titanium-nitride.
The cleaning of described grantie decoration plate material comprises thick cleaning, matting, ion bombardment, and wherein thick cleaning can adopt acetone organic solvent and washing composition that the wax stain and the oil stain of surface of granite are cleaned; Matting can adopt weak base type clean-out system to clean, and adds trisodium phosphate solution as yellow soda ash, and this step is in order to remove oil stain that surface of granite left behind, wax stain and evaporable acetone class organic solvent not; Enter at last and carry out icon bombardment cleaning in the vacuum oven.
The concentration of sodium carbonate of selecting for use in the above-mentioned matting is with 25 grams per liters, and tertiary sodium phosphate concentration is good with 25 grams per liters, and cleaning temperature is advisable at 80 ℃～100 ℃.
In order to reach cleaning performance better, in the matting process, can increase ultrasonic cleaning, its vibrational frequency is good in 20000～30000 hertz of scopes.
Above-mentioned icon bombardment cleaning condition is voltage 350V, electric current 50A/ square metre.This step is to disperse away for the silicon oxide that makes the granite in slab remained on surface is ionic condition, can make titanium nitride be reduced to metal titanium on the sheet material because the abradant abrasive material silicon oxide of granite in slab remains in, and causes metal plating progressively to disappear.
Described oven dry is meant granite in slab is placed under 250 ℃～350 ℃ temperature condition, until oven dry.
Described vacuum titanizing is meant the granite in slab after the oven dry placed vacuum oven, and during kindling temperature to 350 ℃～500 ℃, applying argon gas carries out ion bombardment, vacuumizes once more, carries out electron beam evaporation at last.
In above-mentioned vacuum titanizing, be evacuated down to 1.5Pa * 10
-3Condition, the voltage of ion bombardment is 350V, electric current 50A/ square metre is good, applying argon gas 0.4Pa, the electric current of electron beam evaporation are 500A/ square metre.
Described vacuum titanium-nitride is meant the granite in slab after the oven dry placed vacuum oven, and during kindling temperature to 350 ℃～500 ℃, applying argon gas carries out ion bombardment, vacuumizes once more, and nitrogen injection carries out electron beam evaporation at last then.
In the above-mentioned vacuum titanium-nitride, nitrogen injection 0.13Pa, other conditions are identical with the vacuum titanizing.
In vacuum titanizing of the present invention or vacuum titanium-nitride, with the granite in slab is negative electrode, metal titanium is an anode, under the ion bombardment condition, the atom on granite top layer loses electronics and obtains activation, metal titanium is evaporated from target under ion bombardment, deposits to surface of granite and forms metal titanium coating, or be deposited on surface of granite formation titanium nitride coating with the nitrogen that is the ion shape.
Adopt this treatment process, can make surface of granite form metal level, the natural crystal combination of it and the hard indeformable good physical of granite and granite has just formed a kind of very beautiful grantie decoration plate material together.Can form the electrolytic coating of 2-4 μ m like this at surface of granite, metal titanium and nitride metal titanium do not react with atmosphere, through the CASS evidence, can keep nondiscoloration more than 30 years, and particularly nitride metal titanium extreme hardness can reach more than Wei Shi 2000 degree; The vacuum titanizing can make surface of granite present silvery white, and the vacuum titanium-nitride can make granite present 24K gold or golden red, golden purple, Jin Lanse.
The invention will be further described below in conjunction with embodiment:
Embodiment 1: a kind of process for metallizing surface of granite is characterized in that: granite in slab is cleaned with acetone remove the dewax stain earlier, clean with the oil stain of common household detergent to the granite in slab surface; Adopt the yellow soda ash of 25 grams per liters to add the trisodium phosphate solution clean-out system of 25 grams per liters then, the oil stain that under 80 ℃ of temperature, surface of granite be left behind, wax stain and not evaporable acetone clean; Enter at last in the vacuum oven at voltage 350V, carry out icon bombardment cleaning under the electric current 50A/ square metre condition.
After cleaning finishes, the granite in slab that cleans is placed under 250 ℃ of temperature condition, until oven dry.
Granite in slab after the oven dry is placed vacuum oven, be evacuated down to 1.5Pa * 10
