Information
Internal quality standards for domestic straight floor:
 
Shaanxi Hongli Mining Co., Ltd.
 
1. Board surface: The surface of the slate as a natural stone has a slight chromatic aberration and a point of sulphur iron point, water extraction, sand layer and platinum line are normal, but there is no broken sand layer and platinum line. The surface of the board is generally flat and must not have large bismuth pyrite or large areas of depressions or bulges. It must be guaranteed that the four corners of a face are complete.
 
2. Thickness error range:
 
1. Thickness of 10 – 15mm straight floor (300x150mm, 300x300mm, 400x200mm, 600x300mm, 800x400mm, 600x600mm) thickness of 10 – 15mm accounts for about 90% of the total number; because it is artificially divided, the thinnest is not less than 9.5mm, The total number of floors below 10mm thickness (10 – 9.5mm) shall not exceed 5%; the slate exceeding 15mm thickness (upper line not exceeding 15.5mm, ie 15 - 15.5mm) shall not exceed 5% of the total quantity;
 
2. Thickness of 15 – 20mm straight floor (300x300mm, 400x200mm, 600x300mm, 800x400mm, 600x600mm) thickness of 15 – 20mm accounts for about 90% of the total number; because it is artificially split, the thinnest is not less than 14.5mm, overall low The number of floors at a thickness of 15 mm (15 – 14.5 mm) does not exceed 5%; the floor thickness greater than 20 mm (upper line does not exceed 20.5 mm, ie 20 - 20.5 mm) does not exceed 5% of the total number;
 
3. Thickness of 20 – 30mm straight floor (300x300mm, 400x200mm, 600x300mm, 800x400mm, 600x600mm) thickness 20 – 30mm accounts for about 90% of the total number; because it is artificially split, the thinnest is not less than 19.5mm, overall low The number of floors with a thickness of 20mm (20 – 19.5mm) shall not exceed 5%; the slate of more than 30mm thickness (upper line not exceeding 30.5mm, ie 30 – 30.5mm) shall not exceed 5% of the total quantity;
 
3. Dimensional tolerances for length and width: The allowable tolerance is +/- 1 mm.
 
4. Angle error: four angles of 90°, the angle error on the long side is within 1°, and the angle error on the wide side is within 0.5°;
 
5. For the quality of the process board with special requirements, it should be agreed and specified according to the customer's requirements.
 
Wood box (no top cover) quality requirements:
 
1. The middle column of the outer wooden strip must be strong, the width of the wooden strip shall not be less than 60mm, and the thickness of the wooden strip shall not be less than 20mm.
 
The width of the cross strip and the border strip shall not be less than 50mm, and the thickness shall not be less than 15mm; and the angles of the two ends of the cross strip shall be respectively resisted on the wooden strip of the column and the wooden strip of the frame, and there shall be no gap; the number of nails at the intersection Not less than 3, and the triangle is staggered into the wooden strip to ensure stability and strength;
 
2. The width of the iron wrap angle shall not be less than 45mm, and at least 3 nails shall be nailed at each end. Two of the nails shall be straightened into the inner wooden strip of the frame; the other nail shall be directly nailed into the top of the wooden strip outside the frame.
 
3. A 5 mm thin wooden strip should be placed in parallel between each layer of slate floor to reduce damage. A thin strip of 5 mm should be placed between each floor to avoid bumping and falling corners during transportation.
 
4. The height of the bottom sleeper is not less than 60mm;
 
5. The crate floor must be flat and strong
