Meixin Brush Factory teaches you how to use stone abrasive brush technology_FAQ

1. What is a stone abrasive brush (also called an antique stone brush)? A stone abrasive brush is a special tool for antique processing of natural stone. It is made of stainless steel wire or special nylon brush wire containing silicon carbide. It is available in different sizes and specifications for use with hand grinders, grinding and polishing production lines, floor refurbishing machines, manual grinders and other equipment. The stone grinding brush mainly uses the principle of brushing to make the stone surface appear similar to the natural wave surface or cracks after weathering, and the surface achieves satin mercerized and antique distressed effects, which look like it has been used for hundreds of years. At the same time, it improves the antifouling of the stone. Waterproof performance, and make the surface of the treated stone have a non-slip effect. 2. The working principle of the stone grinding brush. The brush wire used in the stone grinding brush is evenly scattered with silicon carbide sand particles with sharp cutting edges. When the brush is pressed and moved on the surface of the stone, the brush wire will bend arbitrarily along with the uneven surface of the stone. , Use the sharp edges of sand particles to polish and polish the stone surface. As the number of brushing meshes increases, the volume of the sand particles gradually decreases, and the grinding marks are gradually reduced, until the brushed stone remains on the surface The unevenness also shows the satin-finished mercerizing effect. 3. Classification of stone abrasive brushes 1. Classification according to specifications: stone abrasive brushes mainly have three shapes: horseshoe-shaped, φ110mm round, and Fikert-shaped (bra-shaped). Among them, the horseshoe shape is used for hand grinders, grinding and polishing production lines, and beautiful stone stone renovation machines in the industrial production of stone; the round shape is used for small manual polishing machines, beautiful stone floor renovation machines, etc. 2. According to the number of meshes, there are: wire brush, 36#, 46#, 60#, 80#, 120#, 180#, 240#, 320#, 500#. Generally speaking, wire brushes and 36# abrasive brushes are used to remove surface loose objects and plate surface shaping; 46#, 60#, 80# are used for rough grinding; 120#, 180#, 240# can be rough polished; 320 #, 500# is fine polishing, so that the stone surface can achieve a mercerized effect. If it is the first time to use the grinding brush, various models should be tested, and the choice should be made according to the type of stone and the grinding effect that needs to be achieved. 4. How to choose a good high-quality stone grinding brush. A high-quality stone grinding brush should have the following characteristics: 1. The brush wire should not fall off during the working process. 2. The fixing of the brush wire in the brush base should be made of high-strength stainless steel to prevent Rust. 3. The wavy curved brush wire should be used. 4. The abrasive sand in the brush wire should not fall off due to the bending of the brush wire. 5. Reasonable brush wire height and density. 6. The brush wire should have high hardness and toughness in a humid environment. 7. The brush wire should have good bending recovery. 8. The brush wire should have good wear resistance.

Welcome to log in: www.mxbrushmachinery.com, contact Xu Shengli; telephone number five, the use of stone abrasive brushes in the production and processing of stone abrasive brushes Pay attention to the following points during the process: 1. Add cooling water during grinding and polishing operations. Prevent the brush wire from deforming due to the high temperature generated when the brush wire is rubbed at high speed. 2. With the working sequence of the grinding brush model from coarse to fine, the pressure on the grinding head of the brush should also be from large to small. 3. The number skipping should be reasonable. Excessive reduction of intermediate links will affect the grinding effect, but may increase production costs. 4. Use wire brushes as much as possible. The wire brush used in the first process can reduce the wear of the abrasive brush wire on the rough surface and prolong the service life of the abrasive brush.
