How to process stone sandblasted surface and antique surface?

With the rapid development of stone technology, the treatment of stone surface effects has become more and more diverse. At present, the internal surface effects of the stone industry mainly include the following categories: smooth surface, matte surface, pickling surface, sandblasted surface, fired surface, chop Axe surface, litchi surface, hammered surface, brushed surface, antique surface, mushroom surface, natural fracture surface, special surface, etc.

Now let’s introduce the stone sandblasting process method:

  Sandblasting of natural stone (stone sandblasting surface) is to use angular emery, quartz sand, river sand and other abrasives to impact the surface of the stone under the drive of compressed air (or water), resulting in a similar glass Stone surface processing with frosted effect.

   Stone sandblasting has a wide range of applications. It can not only be used for the processing of natural stone slabs such as thin plates and specification plates, but also can process special-shaped stones such as lines, pillars, railings, steps, corners, and sandblasting. It is also widely used in stone carving. At the same time, stone sandblasting is also like other treatment methods, which can be used for small-scale sandblasting and large-area sandblasting.

Of course, the sandblasting treatment of stone is not limited to the surface processing of the stone as a decorative surface, but can also be used in the restoration of the stone. For some stones that have been installed, if there is a serious stone texture or stone pollution that cannot be repaired, we The surface sandblasting method can be used to deal with the serious and pollution problems of the stone.

  Stone sandblasting process:

  The stone sandblasting process is very simple. If it is a full-area sandblasting, you only need to directly perform sandblasting on the rough-ground stone plate; if it is partial sandblasting, you must not need sandblasting Wrap the treated part with rubber sheet or other sandblasting protective film before spraying.

  There are currently two main methods for stone sandblasting, one is manual sandblasting, and the other is machine sandblasting.

  Among them, manual sandblasting is usually dry sandblasting machine, and machine sandblasting is divided into two categories: dry sandblasting machine and liquid sandblasting machine. Dry sandblasting machine can be divided into absorption type and press-in type.

Suction dry sandblasting machine

   The suction dry sandblasting machine is powered by compressed air, and the negative pressure formed in the spray gun by the high-speed movement of the airflow, sucks the abrasive into the spray gun through the sand pipe and shoots it through the nozzle, and sprays it to the processed surface to achieve the desired processing goal. . In the suction dry sandblasting machine, the compressed air is not only the power supply, but also the acceleration power.

Press-in dry sandblasting machine

  The press-in dry sandblasting machine is powered by compressed air. Through the working pressure established in the pressure tank by the compressed air, the abrasive is pressed into the sand pipe through the sand valve and ejected through the nozzle, and sprayed to the processed surface to achieve the desired Processing items. In the press-in dry sandblasting machine, the compressed air is not only the material supply power but also the power and the acceleration power.
