Light Emparador marble is produced in Hebei, English name EMPERADOR LIGH. Its texture is thick and magnificent, and its natural and gorgeous colors make it widely used in architectural decoration and handicraft production.
Scope of application ：
Floors, walls, countertops, pillars, wash basins, etc.
Introduction of processing technology：
The inspection of the angle is measured with a 90 steel square ruler with an internal angle perpendicularity tolerance of 0.13mm and an internal angle side length of 500mmx400mm. Place the short side of the square rule against the short side of the plate? The long side of the square rule against the long side of the plate? Use a feeler gauge or vernier caliper to measure the maximum gap between the length of the plate and the long side of the square. When the length of the plate is less than or equal to 500mm? Any diagonal angle of the plate can be measured? When the long side of the plate is greater than 500mm? Measure the four corners of the plate. The measured value of the maximum gap represents the angular tolerance of the plate? The measured value is accurate to 0.1mm.
Inspection of appearance quality ①Pattern tone Put the plywood plate and the inspection plate flat on the ground? Stand 1.5m away from the plate and visually inspect. ② Manual chiseling Place the plate flat on the ground? Visually inspect the plate at a distance of 1.5m. ③ Number of colored lines Visually check the number of colored lines. ④ Missing angle and chipping angle Use vernier calipers to measure the length, width and height of the defect and visually check the number of missing angles. ⑤Steps Use a vernier caliper to measure the height of the steps? Measure the maximum value as the height of the steps. ⑥Cracks Visible cracks are visually inspected? Hidden cracks are hammered? That is, a metal hammer is used to strike the plate? By sound? Generally mute to identify whether there are cracks? OK. ⑦Color spots Use vernier calipers to measure the size of color spots and visually check the number of color spots.
Hardness Marble is relatively soft stone? In the Mohs hardness scale, MOHS?? Marble grade is about 3? The highest is 10?. Marble and teeth are made of calcium. If you bite too hard? The teeth will break? Eat too much sugar? The teeth will pierce. The same is true of stone. If the reagents used on the stone surface are improper? The stone will start to rot? Form holes. The following is the famous Mohs hardness table? MOHS?. This standard was established in the early nineteenth century? It helps to identify the strength and hardness of the stone used in order to take corresponding measures in application. For example, "stones with lower hardness require softer reagents", and the number of scrubs is more frequent.
Mohs hardness table 1. Talc 2. Gypsum 3. Calcite? Most marble? 4. Fluorite 5. Apatite 6. Feldspar? Granite? 7. Quartz? Granite? 8. Topaz 9. Corundum 10. Diamond The Mohs hardness scale is used to measure the degree of stone wear resistance. When the sediment or gravel is harder than the stone surface, it will scratch the stone. For example, a hard plastic with a hardness rating of about 2.0? It will not scratch calcite (marble) with a rating of 3. Sand of hardness 6 will scratch calcite of level 3 but not quartz stone of level 7 or granite. The higher the hardness level? The more wear-resistant. Hardness measurements of foreign deposits in buildings from 3.0 to 7.0
