red granite plate production processes and points to note

Granite is a volcanic lava from the under considerable pressure in a molten state to the granite surface crust uplift, magma is not ejected the ground, and slowly cooled and solidified in the sds drill bits  ground structure formed after the rock, a Acid plutonic igneous rock types, are igneous rocks. Igneous, also called acid crystals plutonic igneous rock is the most widely distributed as a rock, its composition of silica-based, accounting for about 65% -75%.
Benefits include granite features high load resistance, compressive strength and good ductility grinding, granite very easy to cut and shape, you can create a thin slab, etc. In short, granite with superior endurance capacity.
Granite red plate production process and technology:
First of ferric chloride dissolved in water, and add a small amount of a catalyst made of stain.
Then put into granite and edge polishing pads  completely immersed in the staining solution.
After a certain time in the soaking removed for cleaning, drying, color is obtained after red granite.
(Note soaking time should be according to Stone, color, water absorption, stone clearance and so different to set)
Manufacturing production process should pay attention to the main points:
Color concentration: Different concentrations to get different color effects, the production should look at the actual case may be, the general concentration of 20% for the best.
Soaking time: to have tile cutting blades  enough time to good coloring short time, but the time is too long the job efficiency is not high. Generally take 3-4 hours as well.
Color liquid PH value: PH value is too large and too small right after the color change and gloss granite color is not good, and generally two for the best.
Drying temperature: generally choose 200-250 ℃ (Celsius) is appropriate.
Drying time: usually about 2 hours.
