Generally, stone needs to be polished before it is used, because the stone will be aging and contaminated after time. And polishing is a meticulous processing technology, some people will call it surface enhancement technology. In the stone polishing process, there are more or less factors that affect the polishing effect and quality, so what are the factors that affect the stone polishing?

The influence of the stone itself

1. Types of stone

The different types of stone will affect the polishing effect. Stones with different mineral compositions have different polishing process characteristics. For example, a stone mainly composed of serpentine minerals, such as large green marble, is a tough stone that can be polished, but is not easy to polish.

2. Mineral composition

The stone contains a certain amount of earth minerals, which will also affect the gloss of the stone. A typical example is the red snail. The name of the rock is selected layer stone biological limestone. The panels sawn in parallel planes are flower-shaped and biologically decorated, more like a clam shell, which is very beautiful, but because the ore contains a certain amount of clay minerals, it is difficult for the polished panel to achieve a gloss above 85.

3. Poor quality

Loose granite is often cloud-like minerals that have undergone a certain degree of weathering, such as clay or hydromica, and its polishing effect is difficult to achieve the polishing level of fresh granite. This should be the quality of the stone.

The influence of polishing process factors

1. Polishing agent

In theory, different minerals should use different polishing agents. Although the polishing agent is a special polishing material, the difference between it and the abrasive material is mainly in the processing mechanism. In principle, there are some low-hardness micro-powder materials that can also be used as polishing agents. But generally, high-hardness polishing agents are better than low-hardness ones and have a wide range of applications. Diamond polishing powder can achieve satisfactory polishing results for most stones.

2. Polishing liquid

Water is a commonly used polishing fluid. It can not only play the role of grinding and cooling, but also as a medium for physical and chemical effects in the polishing process. If the stone is polished mainly by mechanical grinding, such as diamond powder, the polishing liquid generally uses oily organic liquids, such as sewing machine oil. Its cooling, lubricating and dispersing effects are excellent. Diamond pastes are available in both water and oil, and colorants can also be added. The formula is: abrasive, dispersant, carrier, water and coloring agent.

3. Polishing disc

The smooth stone panel with flat specifications is a form of expression and processing of stone surface grinding. Hard disks made of metal materials are often used as polishing discs. The polished surface of the floppy disk is easy to yield into a concave surface when the stone is pressed, which is suitable for curved surface polishing. The medium hard disk has good abrasion resistance, good adsorption and certain elasticity, and it has a good polishing effect on flat stone.

4. Polishing head

The feed rate of the polishing head has a great influence on the polishing effect. Studies have shown that with the increase of the feed rate of the polishing head, the surface gloss of the stone will decrease, but if the feed rate is too low, it will accelerate the wear of the head and reduce the production efficiency. . In addition, the operation mode of the polishing head should be coordinated with the operation mode of the coarse and fine grinding heads. The operation mode of the grinding head is divided into vertical and horizontal and density.

5. Polishing process parameters

The process parameters include the concentration and supply of the polishing agent, the pressure and linear velocity during polishing, etc. Before being less than a certain concentration value, the polishing speed increases with the increase of the polishing agent concentration. After the concentration value reaches the limit, if the concentration is increased again, the polishing speed will decrease instead. Similarly, when the supply amount of polishing agent is at a certain value, the polishing speed is high, and if the supply amount continues to increase, the polishing speed will decrease instead. Properly increasing the pressure during polishing can increase the polishing speed, but if the pressure is too high, the grinding effect will be strengthened, which is not conducive to the formation of a glossy surface. The polishing speed depends on the rotation speed of the polishing disc, but if the linear speed is too high, the polishing agent will be thrown out, causing waste.

The above is a complete introduction of the factors that affect stone polishing. It can be seen that the influencing factors of stone polishing mainly depend on two major aspects. One is the stone itself, which is an internal cause; the other is the polishing process, which is an external cause. As far as the impact of the stone itself is concerned, the main factors are the type, mineral composition and quality of the stone. The diamond polishing pad produced by our company can highly polish stone materials under the condition of adding water. The grinding disc has sharp grinding, good heat resistance and pressure resistance, and has the advantages of fast glazing, high brightness and resistance to fading without changing the color of the stone itself.

Resin polishing pad is a flexible processing tool made of diamond as abrasive and combined with composite materials. The back is glued with Velcro cloth, which is glued to the joint of the grinding machine. It is used for grinding and can be used for stone, ceramics, glass, Special-shaped processing of floor tiles and other materials.

Requirements for the use of different specifications of resin polishing pads:

1. When working, the workpiece should be fixed, and the profile positioning should conform to the direction of the knife, so as to avoid abnormal cutting, do not apply side pressure or curve cutting, and the knife should be smooth to avoid the impact of the knife edge contacting the workpiece, which may cause damage to the polishing pad, or The workpiece flew out and an accident occurred.

2. During work, if abnormal sound and vibration, rough cutting surface, or peculiar smell are found, the operation must be terminated immediately, and the fault must be checked in time to avoid accidents.

3. When starting and stopping cutting, do not feed the tool too fast to avoid broken teeth and damage.

4. If cutting aluminum alloy or other metals, special cooling lubricants should be used to prevent the saw blade from overheating, generating paste teeth, and other damage, which affects the cutting quality.

5. The equipment chip trough and slag suction device ensure unobstructed, to prevent the accumulation of slag and block, which affects production and safety.

6. When dry cutting, please do not cut continuously for a long time, so as not to affect the service life and cutting effect of the polishing pad.

The floor is used frequently in the building, so it is easy to be damaged. Due to the limitation of process technology, many old floors (such as epoxy, emery, terrazzo, floor tiles, cement floor, etc.) gradually expose their defects, and there are differences. The problem of form and degree, so to a certain extent, it needs to be refurbished. Today, diamond water mill manufacturers will come to introduce you to several renovation construction techniques commonly used in industrial floor renovation.

Epoxy floor construction technology

1. Plain treatment: grinding, repairing and dust removal according to the condition of the plain

2. Epoxy Primer: Adopts strong epoxy primer roller coating to improve surface adhesion.

3. Epoxy approved soil: According to the actual needs of construction of several passes, it is required to achieve flat and no holes, no batch of knife and sand printing

4. Epoxy topcoat: two coats of solvent-based epoxy topcoat or anti-slip topcoat.

5. Construction is completed: people can be loaded after 24 hours, and pressure can be heavy after 72 hours. (25 ° C prevails, the opening time at low temperature needs to be moderately extended).

Concrete seal curing agent floor (mirror type) construction technology

1. Grass-roots treatment: before construction, clean and clear the sundries, oil, and curing agents on the ground. Cement-based repair mortar was used to repair the pits and cracks on the ground and cured for 3 days.

2. Grinding the ground: The surface quality is poor and rough: install a rough diamond module on a water grinder (7.5KW machine), add water to grind the ground, and after basic smoothing, change the fine grinding heads separately, and finely grind the ground, The same process is water milled) until the floor is smooth. After grinding the ground, clean the ground with water, and use a vacuum cleaner to suck up the sewage. For better, smooth new wear-resistant floors, you can directly apply concrete seal curing agent.

3. Brush concrete seal curing agent: After the floor is cleaned and the surface is allowed to air dry, brush concrete seal curing agent can be applied. Use a roller or sprayer to evenly apply the curing agent to the ground, and the average application amount is 10 ㎡ / kg. If the base surface is poor and has strong permeability, it must be painted twice after 1-2 hours; after about 1-2 hours (before the material is dry and shiny), spray some water on the ground to wet the material. Use a broom or a floor to scrub and wash the surface to allow the material to penetrate the ground, and repeat 2-3 times, then rinse the ground to remove excess material on the surface.

4. Ultra-fine polishing (mirror fruit): To improve the gloss and light fruit of the ground to reach the mirror fruit, a 1.1KW high-gloss polishing machine can be used, and 500-mesh, 1000-mesh, 2000-mesh, and 3000-mesh diamond polishing pads can be adhered to the disc. Watering ultra-fine polished floor.

Wear-resistant floor construction technology

1. Removal of scum: Slowly and evenly destroy scum on the surface of a single concrete with a machine equipped with a disc.

2. Spread material: Spread the specified amount of 2-3 wear-resistant material on the concrete surface in the initial setting stage. After the abrasion-resistant material absorbs moisture, the mechanical operation of adding a disc is performed, and when the abrasion-resistant material is hardened to a fixed stage, the abrasion-resistant material spreading operation is performed twice.

3. Disc operation: After the abrasion-resistant material absorbs moisture, perform mechanical operations for installing discs at least three times. The speed of the machine will be degraded depending on the hardening of the concrete. The mechanical concrete operation should be crisscrossed.

4. Finishing the surface: The final modification of the wear-resistant flooring material is processed using mechanical concrete or manual concrete. When polishing, it should be criss-crossed. The angle of the iron plate and the speed of the machinery should be adjusted and cut according to the hardening of the ground surface. .

The polishing pad is a flexible processing tool made of resin as a binding agent and combined with a composite material. Velcro is glued on the back, which is fastened to the joint of the hand-held mill for grinding. Polished granite and other materials are processed in special shapes. The whole process is divided into four stages: rough grinding, fine grinding, fine grinding, and polishing. The processed stone has a gloss of more than 90 °.

There are many types of polishing pads with different composition ratios. Mainly used for grinding and polishing of Shicai stone, glass, ceramics, waist and eyes. (Granite, marble, and other heterogeneous stone corners, inner arcs, outer arcs, planes, glass, ceramic sides, corners, planes, planes of ceramic waistlines) Granularity number: 50 #, 100 #, 200 #, 400 #, 800 #, 1500 #, 3000 #, BUFF. It is widely used in the grinding and polishing of marble, granite and other special-shaped stones. The maximum rotation speed is RPM4500. When grinding, from coarse to fine to polishing, it can meet various needs.

Generally divided into ordinary resin grinding discs and super hard resin grinding wheels according to the grinding material. Ordinary resin grinding wheels are made of white corundum, brown corundum and silicon carbide. Super hard resin grinding wheel is a grinding wheel with diamond or CBN as the main grinding part.

In the production process, diamond wheels are used to polish the belt. Usually, the wheel is removed for cleaning after 5-7 days of operation.

Now we soak it in acetone for 2 hours and then clean it with imported cleaner. The effect is very good, but it is not environmentally friendly and does not save energy. The cleaning of resin polishing pads requires environmental protection and cannot damage the diamond wheel.

The polishing pad has a uniform and standardized particle color system and good flexibility. It is widely used in the processing of marble, artificial stone and other lines, countertop curved plates and special-shaped stone processing. There are multiple shapes to choose from, and different particle sizes are used differently. Colors can be distinguished and can be matched according to the different needs of customers. Then, only using polishing pads is not enough. The following aspects also need attention:

1. When abnormal sounds and vibrations, rough cutting surfaces or abnormal odors are found, the work must be terminated immediately, and faults should be checked and eliminated in time to avoid accidents.

2. During work, the workpiece should be fixed, and the profile positioning should be in the direction of the cutter to avoid abnormal cut-in. No side pressure or curve cutting is applied. The knife is sent smoothly. Flying out and causing an accident.

3. When cutting and stopping cutting, do not go too fast, so as not to break and break the teeth.

4. If cutting aluminum alloy or other metals, use special cooling lubricant to prevent the saw blade from overheating and causing tooth damage, which will affect the cutting quality.

5. Equipment chip discharge slag tank and slag suction device ensure smooth water flow, prevent slag agglomeration, and affect production and safety.

6. Dry cutting, do not cut for a long time, so as not to affect the service life of the saw blade and cutting fruit; when wet cutting, water cutting should be added to prevent leakage.

What is the purpose of different specifications polishing pads?

1. Suitable for the processing of artificial stone, granite and marble. It has a complete and standard granular color system and good flexibility. Easier to machine lines, chamfers, curved plates and shaped stones. The specifications are optional, and various particle sizes are easy to distinguish.
