One Plate thickness: Imported plate is basically about 2CM, domestically produced from 1.4-1.8CM, thickness is not the same, the price is not the same. Therefore, the same quality and color of the board, JS offer different, so when buying it is necessary to ask clearly thickness. Two different machining precision tricky Domestic plate processing accuracy is not enough, some of the same plate thickness of 1.5CM, some 1.6CM thick, length and width dimensions deviation, to increase the difficulty of installing the mason, resulting in poor construction quality is nothing more than equipment can not keep up, the worse the equipment The lower the price. Tricky three polishing equipment Plates have a degree of polishing, some can reach 110 degrees, and some can only reach 70 degrees, so the polishing equipment is not good, the same board has a different degree of polishing, it looks different. Tricky four shoddy The store looks like a first-class board, and it is indeed a Class 2 board for you to use. The difference is in color and processing accuracy. Five materials are not profitable, small materials make money Large materials (large plates, engineering plates) are basically net prices + losses, but the loss of materials can be processed into lines, borders, etc., which is what they can make. Tricky six real ones Stained with 663 into Sichuan Red, the price difference between 100 yuan / square identification staining board to the side of the board, if the same color with the board surface (unpolished case), is stained, the general side is not dyed white hair Stained plates look dull and fade over time. Tricky seven different production methods The marble lines are generally milled with block materials. The cost is high and the quality is good. However, some JS pastes the plates and grinds them into lines. The roughness is poor, but the price is much lower. Tricky eight edging The edging must be done with good craftsmanship. Generally, some of the material suppliers of the stone mills use small workers to grind them. The results are uneven and the luster is not the same. The cost down many edgings and water mills and dry grinding. Points, the quality of the water mill is good, the quality of the dry mill is poor, and the gloss is worse. JS is pumping the oil in the dry grinding place, hoping to achieve the effect of the water mill and obtain a higher profit. Naughty nine Different places of origin use big flower green as an example. There are domestic, Taiwanese, and Greek products. The prices are different. The stores look like they are imported, but the ones that are used for domestic production are the same as large flowers and green ones. Light colored expensive, it is also a place for ghosts. Ten tricky repair Some boards have flaws, JS fixes them with pencils, waxing some boards with subtle cracks, and JS fixes with marble glue and color so that the secondary board can sell to the price of the first board.
