Ancient wood stone polishing technology physics

Ancient wood marble texture clear and smooth, the colors of black and white ash and many other, quite similar to the cross-section of bianco carrara old trees, hence the name. Its solemn yet beautiful decorative effect, widely used. But in the stone care industry, the ancient wood considered "hard light stone club" in an important member. Whether renovation or maintenance, the ancient wood polishing technology, are a problem.

First, the ancient grain physical polishing

1. Procedure

Step one: using a grinder + VD easy to wear pieces, the overall polishing process.

Step Two: After grinding followed by M1-M7 segment to number seven. Equivalent to an ordinary number 50 #, 150 #, 300 #, 500 #, 800 #, 1500 #, 3000 # grinding finish.

2, polishing

Number seven segment M1-M7 mill finish: 63-75 degrees. Average gloss: 67 degrees.

Note: This is purely a physical grinding out above do if gloss sealing glaze over and over will be able to reach more than 90 degrees!. Moreover, the bottom surface is optimized so even delicate, ancient wood can do a whole Bach, and lip and bright!

We will announce the results later, so many stone factory surprised and shocked. Used to seeing on a beige stone class stone care of more than 100 degrees, probably do not understand the grinding out 67 degrees, for this ancient wood stone, what it means - stone factory with high-stress, high-speed machinery, thrown out ancient wood - and only about 50 degrees!

3, the persistence of it?

We intentionally left out of the lobby area not sealed glaze for observing such physical gloss, without any maintenance, after prolonged use what will change.

This area is, after 2015 8, 9, 10, 11, December, and January 2016 test, as of today, January 30, 2016 - in the six-month period allowed to stampede - - gloss decreased only 3 to 5 degrees only.

To dirty, wash on the line artificial quartz stone. Wash still the same transparent, beautiful.

+ Beautiful lasting, consumers do not want that here?

Six months of continuous use

Second, science: Why ancient wood hard polishing?

1, so that the plant had a headache ancient wood

Speaking of ancient polished wood, stone care not only headaches, even the stone processing plant has deep feelings. Because most of the marble at the factory processing, grinding out the physical gloss generally above 80 degrees, that is, when we buy the stone, you can see the original plate gloss.

But the ancient wood in the factory grind out the gloss generally only about 45-55 degrees, much lower than other varieties of marble. Factory solution, is used when the stone polishing wax to fill form gloss 70-80 degrees. However, this method is purely upset.

2, hard light of reason

Not only is the plant, a lot of experienced professional stone care company Take ancient grain is also no way, do not transparent, do not shine. So what is the reason?

① chemical composition

Old wood was black, in that manganese dioxide (MnO2) and carbide components higher calcium content is very low. Ancient grain has obvious rhyolite feature. Its formation is fractured along the hot magma intrusion foundation rock, making contact with hot parts of the secondarily crystallized white. The reach of the high temperature part of the original state, was black. After millions of years of crystallization, the role of co-precipitation, the formation of such a unique stone.

Black part, which is formed by precipitation, without crystallization, structure is more loose, low density, high water absorption, low calcium content, especially in this part of the hard light.

Stone crystal technology is the use of oxalic acid, fluorosilicic acid, silicic acid and other materials react with the calcium stone, calcareous blended generate crystal layer, to achieve light. Therefore, in the low calcium content of ancient wood, whether powder, agents, pulp and other materials, the effect is not good.

② black is not dirt

Black is a strong color contrast, the ability to hide the ugly black stone is worse than the other colors of the stone.

Problems such as scratches stone, black stone even minor scratches, it is very obvious; but white, beige and other stone strong ability to cover scratches. Another example dust, slight dust pollution, but also make shiny black stone surface becomes hazy, honey onyx tiles and white, beige stone dirt ability is stronger than the black stone.

This factor, so that the ancient wood in applications is easier because of scratches and contamination, resulting in low-light vision on light. As follows: ash wood stain on the left more than the right side of the Black Sands, but I can not see.

NOTE: In conclusion, the physical and chemical properties of ancient wood, determines the crystallization on it unable to obtain a high gloss
