With the time going, after almost 5 years of developing our local limstone quarry, the quality of limestone quality getting better and better, pure and hard, color remain stable.
Usually, limestone surface chiselled used as paving stone. Any size, any shape, any thickness in ordianry range workable at our factory. Our factory is about 200km away from Tianjin port, usully, will have some trucks delivered the cargos to the seaport before loading the container. One day will be enough.
Surface treaments
1 Pickling
After pickling first, do the antique processing
2, Honed
The surface is smooth, but low degree polished, resulting in diffuse reflection, no luster, no mirror effect, no light pollution.
3, Coarse grinder (Rough-Rubbing)
The surface is simply polished, so that the machine cuts can not be worn out during the cutting process. It feels rough rough finishing.
4, Machine cutting (Machine-Cut)
It is directly cut and shaped by disc sawing saw or bridge cutting machine, with rough surface and obvious cutting edge.
5, Acid pickling (Pickling)
Corrode the stone surface with strong acid, make it have small corrosion trace, and appearance is more plain than polished surface. Most of the stones can be
Acid washing, but marble and limestone are the most common. Pickling is also a way to soften granite's luster.
6, Litchi (Bushhammered)
Rough surface, uneven, is chiseled on the surface densely cut out small holes, there is a imitation of water droplets for years.
7. Pineapple (Picked)
The surface is more uneven than the lychee processing, just like the epidermis of pineapple.
8, Chiselled
It's also called longan noodles, which are chopped on the stone surface with axes, forming very dense stripe texture. Some are like the effect of longan epidermis.
9. Flamed
The surface is rough. This kind of surface is mainly used for indoor decoration such as floor or commercial building, and the cost of labor is high. High temperature heating
After the rapid cooling, the burning surface is formed. The surface of the fire is usually granite.
10, Cracking (Nature Split)
Commonly known as natural surface, its surface is rough, but it is not as rough as fire. This surface treatment is usually used in mine hand cut or crack chisel to expose the natural stone surface.
11, Tumbled
The surface is smooth or slightly rough, and the edges are smooth and broken. There are several ways to achieve the roll effect.
The 20 millimeter brick can roll in the machine, and the 3 cm brick can also be rolled and processed, and then split into two bricks. Marble and limestone are the preferred materials for rollover treatment.
12, Scrubbing (Brushed)
The surface is old and old. The process is to wash the stone surface and imitate the natural wear effect of stone.
13, Antiquity (Antique) The imitation of stone is processed by the old effect after a certain number of years. It is usually processed with antique brush or antique water.
The general antique abrasive brush is effective and cost-effective, and more environmentally friendly.
14, Fire Antiquity (Flamed+ Brushed)
After the fire, then the antique processing.
