Artificial granite overall grinding construction process

The artificial granite is energy-saving and environmentally friendly, and has no radioactive hazard to the human body. It uses natural marble fragments and calcium powder as the main raw materials. The 5%-8% unsaturated polyester resin is used as a binder, and is formed by vacuuming, normal temperature, high pressure, vibration, and pouring. The appearance is beautiful, the color pattern is natural and uniform, the structure is compact, the wear resistance is strong, the compression resistance is high, the water absorption rate is low, etc., which makes up for the defects of natural stone color difference, hole, crack, crack, high water absorption, etc. It is a modern large-scale shopping mall. High-grade office buildings use a wide range of decorative materials.
   Because some decorative companies do not match the artificial granite when the artificial granite is installed, the construction technology is not correct, the mortar, cement, water and clay are improperly matched, the finished product protection is not in place, twice The business time is tight, so the surface of the artificial granite is scratched and scratched seriously. Empty drums, drums, black seams and cuts are more common. The owners have embarked on a never-ending road to rectification since the opening. The losses are heavy and extremely painful.

   Summary of the problems that occur after the artificial granite paving:

   1. The reason for the black seam: the artificial granite just paving At the end, the caulking treatment is performed without evaporating the water in the mortar, and the moisture in the mortar oozes out from the gap of the artificial granite, causing the caulking agent to become black. (The best time for caulking is 12 days after the artificial granite paving).

   2, the reason for the empty drum: the sticky artificial granite mortar is too large, the sand and cement are not evenly stirred, the glue is muddy and the thickness is uneven. The artificial granite structure is compact and the water absorption rate is low. The multi-water water under the artificial granite cannot migrate out of the granite surface, and the clay shrinks quickly. Some people walk on the granite after the paving, which may cause the granite to loosen and blast.

   3. Causes of scratching and loss of light: After the artificial granite paving is finished, the finished product is not protected, and the on-site debris is stacked without a rank, sandstone hard object scratching artificial joint Stone surface, causing scratches, scratches, and loss of light.

   4, the cause of the fracture: the artificial granite has no back mesh glue at the bottom, so it is very brittle, the construction workers hammer hard, the granite is easy to be cracked, the bottom of the cement mortar Shrinkage, dark cracking into a crack into a fracture (the cause of the fracture is also transport, handling, placement, etc. caused by improper cracking, no surface can be seen without cracks, after cement paving, cement shrinkage, a few days The post-cracks become very pronounced as fractures).

   5, the reason for the rise of the middle of the drum kit: the use of strong alkaline cement squeegee when laying the artificial granite, the bottom of the artificial granite is about 3mm by the strong alkali cement, due to The artificial granite is not permeable, the groundwater gas migrates upward, and the water vapor passes through the strong alkali corrosion layer and the top cracked artificial granite surface.

   Overall grinding construction process:

   1. Use water hammer to blow the 6MM hole out of the artificial stone drum bag. Suck and dry.

   2. Use water-based epoxy glue to inject the glue into the artificial granite hole with a high-pressure syringe. To be saturated, the water-based epoxy glue is hydrophilic and can absorb the hole. A small amount of excess water, after 24 hours, the waterborne epoxy glue is fully cured.

   3. Use 307 unsaturated polyester resin and artificial granite to mix evenly with the same color, and repair the cracks and holes in the artificial granite block. After the glue is completely dried, the diamond-cut abrasive is used for the trimming.

   4, rough grinding: use 50#, 150# diamond resin hard abrasive or diamond bitumen 60#, 120#, 220# grinding block (rough grinding do not use soft water mill) The piece is ground, easy to appear wave, affecting the flatness.) The coarse grinding water supply is large. After each abrasive grinding, it should be completely absorbed. Check whether the deep scribe line left by the cutting abrasive is worn away with 50# abrasive, and so on. The machine is well-grinded and the rough grinding accounts for 45% of the total grinding time. It is the key link to ensure the quality of the completion of the project.

   5, fine grinding: using 300#, 500#, 1000# diamond resin hard abrasive, fine grinding accounted for 35% of the overall time, fine grinding to 500# after the beginning When the light appears and is finely ground to 1000#, the gloss can reach 50 degrees.

   6. Fine grinding: using 2000#, 3000# diamond resin hard abrasive or diamond resin soft water grinding disc for grinding, fine grinding accounts for 20% of the total grinding time, fine The gloss after grinding is not improved, but the surface density of artificial granite is improved, which lays a solid foundation for oxalic acid blocks and polishing powder and pulp polishing.

   7, polishing: use power 2HP or more, speed 175—210 rev / min, weight 70 kg crystal machine, animal hair content 70% animal hair pad with polishing powder Or polishing slurry with a small amount of water for polishing, after polishing, the surface of the artificial granite can reach more than 80 degrees.
