Due to the color difference and appearance defects of natural stone, the product needs to be dry lay to achieve a perfect decorative effect. The quality of the stone dry lay effect is directly related to the overall decorative effect.
Dry lay refers to laying the processed products according to the axis position, area, elevation, sub-elevation, floor, and other parts one by one in the plan view of the drawing, and observing the on-site effect. If the color is different, adjust, replace, surface dyeing, make-up treatment, etc. in time.
Day Lay of Cut to Size
According to the agreement board (sample) provided by the customer, select and process the material, and then the cut to size are dry lay and color separated one by one.
After color separation according to the on-site color, ensure that the axis position (front) or the main facade color is consistent, and the color is slightly different on the sub-elevation, corner, or high floor of the shaft position.
But the color should be basically the same, the transition is natural, and there is no difference in color overall. According to the plan view and the list of processing dimensions, write the dimensions of each part on the side of the product one by one, and indicate the part, axis position, box (crate) number, and put it on a shelf, and so on.
The bridge cut products can be processed according to the planned size, which can save time and improve efficiency.
Reasonable Layout of Big Slabs
According to the sample provided by the customer, cut by the gangsaw machine after selecting the blocks, calculate how many square meters of slabs can be got from a certain cubic meter of blocks, and then divide the slabs on the racks which are polished by the automatic polishing machine according to the color.
A detailed quality schedule is made. Then they are transferred to the bridge cutting so that the next process can be prepared in advance or purchased extra slabs.
The batcher calculates the material plan in time and accurately according to the drawing list and the detailed list of the plan. First, it is necessary to ensure that the color of the main facade (front) is consistent with the sample, and then adjust according to each axis elevation, area, and floor.
Use slightly different colors on the back, corners, secondary main surfaces, and high floors (over 10th floor). However, the color of the entire facade (parts) should be transitional naturally, and no color difference can be seen.
It is calculated that how many large-size tiles and small-size pieces can be cut per big slab so that large and small products can be cut together.
The bridge cutter must be processed strictly according to the plan. If there are more materials-saving methods, they can be adopted first. Pay special attention to the products with veins, pay attention to the veins direction for the same vein direction products, and the veins should be continued for the products with continuous veins. And number it on the side of the product and marked by the arrow to indicate the direction.
Dry Lay of Delivered Products
The products produced according to the processing plan are transferred to the dry lay area and layered one by one according to the layout plan of the drawing. The surface of the product is wiped clean and the overall effect is checked.
If there is a difference in color, adjust and replace it, and ensure that the color of the main facade is consistent. If the colors of other areas and parts are different, switch between the same specifications in the same area and the same part, and ensure that the color is gradually transitioned from light to dark, from near to far, from low-rise to high-rise, and the obvious color variation cannot be seen standing at 1 meter.
The tiles with obvious different colors (different veins and grains) should be replaced in time. Although the tiles have been dry laid already in the previous process, the color of the natural stone in the same mining area is different due to different locations, and the same slab surface will have color variation, and the veins and grains are also unevenly distributed.
In addition, there are also factors such as color lines, dark spots, and impurities inside the stone, so the second dry lay is necessary.
