Stone parquet is a beautiful natural stone painting that people use art to conceive and replace the pigment with stone. It is mainly made up of the natural unique color, texture and material of natural stone, combined with clever artistic conception and design.
Stone parquet can be seen as a development and extension of mosaic technology. It is a new stone product derived from the combination of mosaic technology and new processing technology and technology. Like the early stone mosaic, mainly the stone plate products, this can be seen as an enlarged version of the stone mosaic, and later due to the application of waterjet technology and processing precision, the stone mosaic mosaic mosaic technology has been brought to the fore. Extremely, it has formed its own unique style. However, stone mosaic in foreign countries is still in the category of stone mosaic.
Due to the rich and varied layout effect of natural marble, and the fine texture of the marble, the hardness is moderate, which is very suitable for the processing of the mosaic. Therefore, most of the stone mosaics are made of marble, so the so-called stone mosaic, sometimes also refers to Marble mosaic. There are also newly developed sandstone mosaics and slate mosaics that are also very special, but with relatively few applications.
With the development of stone processing technology and technology, as well as the complexity of the pattern and design of stone mosaic, stone waterjet cutting equipment is widely used in the processing of stone mosaic, and for complex parquet design, waterjet Indispensable tools, so the stone mosaic is also known as the water knife parquet.
First, the principle of processing stone mosaic
Stone mosaic is widely used in modern architecture for decoration of the ground, walls, countertops, etc., with its natural beauty (color, texture, material) and people's artistic conception to "spelt" a beautiful pattern.
The processing principle is: using computer-aided drawing software (CAD) and computer numerical control programming software (CNC) to convert people's designed patterns into NC programs through CAD, and then transfer the NC programs to CNC water cutting machines, which will be different. The material is cut into different pattern parts by a numerically controlled water cutter. Finally, each stone pattern component is manually spliced ​​and bonded into a whole to complete the processing of waterjet parquet.
Second, stone mosaic design and processing
(1) Design of stone mosaic
In order to design a stone art that is both beautiful and practical, artistic and consumer-loving, it is necessary to go deep into life, observe and understand people's love and needs, and capture creative inspiration from life. The composition of painting must be derived from life, higher than life, and unconventional. As long as you observe more and be willing to brain, your potential and function will be fully utilized, and good works of art will be displayed on the drawing paper.
(2) Selection of stone parquet
The raw materials of the mosaic are extremely rich, and the corners of the materials are everywhere, and can be utilized. As long as you carefully select the high-quality materials that are more brilliant in color and stone and stone, and art processing, you can create colorful art treasures.
Stone parquet, small corner scraps of various stone materials, large-scale sheet metal. Through the design, selection, cutting, sticking, polishing, polishing and other processes, to create stone crafts with ornamental and artistic. It is an art pattern ornament integrating stone processing art, decoration design art and aesthetic art. Decorated on the surface of the floor, walls and table furniture, it gives people a feeling of refreshing and generous. The large jigsaw puzzles are embedded in the grand auditorium, the big ballroom, and the square of the Grand Place. Their majestic and grandeur will summon you to a bright future.
Material selection: In principle, the material selection of the stone parquet is determined according to the material requirements of the customer when ordering. In the case that the customer did not propose any material selection requirements, the materials were selected according to the national material selection standards of the national stone industry.
Color: The same color of the whole stone mosaic must be the same, but for some materials (Spanish beige, old beige, coral red, etc.), and the color difference on the same plate itself, the color is gradually changed. , based on the principle of not affecting the aesthetic decoration effect of the mosaic. When it is really impossible to achieve a good decorative effect and meet the customer's processing requirements, the processing can be selected after obtaining the customer's consent.
Grain: The direction of the grain in the processing of stone mosaics must be determined by specific conditions. There is no absolute standard for reference. In the case of a round stone mosaic, the texture can be in the circumferential direction or in the radial direction. Whether in the circumferential direction or in the radial direction. It is necessary to ensure the consistency of the lines. In the case of square stone mosaic, the grain can be radiated along the length direction, or can be radiated along the width direction or simultaneously radiated along the long main attack width direction to the four sides. As for how to do it, the processed stone mosaic can achieve the best decorative effect.
(3) Production of stone mosaic
Stone parquet processing is divided into five steps:
1. Draw the mold. According to the design requirements, the mosaic pattern is drawn on the drawing paper, and the carbon paper is copied on the three plywood with the carbon paper, indicating the color of the stone used in each pattern. According to the direction of the connection between the patterns, write the number to prevent the mess. Then use a sharp knife to cut the pattern mold along a small piece of the pattern line. The line of the cut-off should be vertical, not inclined, and the arc angle cannot be moved.
2, accurate material selection, pre-widthing. There are red, white and black stones in the mosaic pattern. Some of the same color also has depths. When selecting materials, it is necessary to accurately select slate with clear texture, fine grain, pure and consistent color, and no cracks according to the drawings. According to the shape and specification of the mold, it is accurately drawn on the selected stone, and the piece is cut and cut by one piece. When cutting, the peripheral part should have a machining allowance, and the pre-width is 1-2mm, in order to prepare for relocation.
3, carefully run in, grouped and glued. The reserved part of the cut pattern stone is slowly ground to the position of the connecting line, and the positioning is carried out with a small amount of adhesive material, and then the whole pattern is glued with a piece of strong glue. When bonding, according to the connection situation of each small pattern, it is divided into several groups, firstly grinding and splicing from the center, then grinding and splicing separately, then grouping and arranging and splicing together, and finally grinding and splicing with the frame, so that the method is splicing, ergonomics Fast, good quality, not easy to walk.
4, toning and seaming, dredging reinforcement. After the whole pattern is glued, mix the color with epoxy resin, stone powder and color material to make the color and stone color absolutely similar. Add a small amount of drier to mix and quickly infiltrate into the gap of each joint. Scrape the surface color. Spread the fiber gauze, sprinkle with stone powder and resin, evenly smooth, so that the gauze and the stone plate.
5, polishing and polishing. Place the glued stone slabs on the grinding table smoothly, smooth and smooth, not sand, and polished with wax.
Third, the stone mosaic acceptance criteria
1. The same stone type has the same color, no obvious color difference, color spot, color line defect, and can not have yin and yang color;
2. The texture of the stone mosaic is basically the same, and there is no crack on the surface of the board;
3, the peripheral size, gap, pattern stitching error is less than 1mm;
4. The flatness error of stone mosaic is less than 1mm, and there is no sand road;
5. The surface gloss of the stone mosaic is not less than 80 degrees;
6. The color of the adhesive used to bond the color of the gap or the stone should be the same as the color of the stone;
7, the diagonal line, the parallel line should be straight, to be parallel, the arc angle can not be moved, the sharp corner can not be blunt;
8. When the stone mosaic products are packaged, the time is facing the glossy surface, and the installation direction indicator number is marked, and the qualified label is attached.
