Information
Internal quality standards for domestic process boards
 
Shaanxi Zhenping County Hongli Mining Co., Ltd.
 
1. Board surface: The surface of the slate as a natural stone has a slight chromatic aberration and sporadic small point sulphur iron spots and water extraction lines are normal. The surface of the board is required to be flat, and there must be no bent plates or slabs, and there must be no broken white gold wire and sand-sanding lines, water-drawing lines and penetrating smelting pyrite or depressions or bulges. There must be no penetrating cracks inside;
 
2. Thickness error range:
 
1) The thickness of the small panels (100x100mm, 150x150mm, 200x200mm, 250x100mm, 250x150mm, 250x250mm, 300x100mm, 300x150mm, 300x200mm, 400x150mm, 400x200mm, 400x250mm) is 4-6mm, accounting for about 90% of the total number; because it is artificially divided, The thinnest shall not be less than 3.5mm, the total number of slate below 4mm thickness (4 – 3.5mm) shall not exceed 5%; the slate exceeding 6mm thickness (online no more than 6.5mm, ie 6 - 6.5mm) shall not exceed the whole 5% of the quantity;
 
2) The large thickness of the large panels (450x250mm, 500x250mm, 500x375mm, 600x300mm, 600x450mm, 610x305mm, 610x460mm) is 5-7mm. If the buyer has special requirements, it can be made according to 6-8mm or 7-9mm.
 
3) Large panel 650x325mm, 650x388mm thickness is generally 6-8mm, if the buyer has special requirements, it can be made according to 7-9mm.
 
4) The large panel 5-7mm thickness error standard is as follows:
 
The thickness range of 5 – 7mm accounts for about 90% of the total number;
 
Less than 5mm (4.5mm in thickness, ie 5-4.5mm) shall not exceed 5% of the total quantity; thickness above 7mm (7.5mm in thickness, ie 7 – 7.5mm) shall not exceed 5%
 
5) The large panel 6 – 8 mm thickness error standard is as follows:
 
The thickness range of 6 – 8mm accounts for about 90% of the total number;
 
Less than 6mm (5.5mm thick thickness, ie 6 – 5.5mm) shall not exceed 5% of the total quantity; above 8mm thickness (upper thickness of 8.5mm, ie 8 – 8.5mm) shall not exceed 5%
 
6) The large panel 7 – 9mm thickness error standard is as follows:
 
The thickness range of 7 – 9mm accounts for about 90% of the total number;
 
Less than 7mm (6.5mm thick thickness, ie 7 – 6.5mm) shall not exceed 5% of the total quantity; above 9mm thickness (9.5mm thick thickness, ie 9 – 9.5mm) shall not exceed 5%
 
3. Dimensional Tolerance of Length and Width: As a process board, the length and width are generally left with a margin of 10mm – 15mm for edge trimming when processing finished products. If the buyer asks us to machine to the size (fixed length) at the factory, the allowable tolerance for length and width is +/-1mm.
 
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 technical board with special requirements for customers, the internal quality standard should be separately indicated.
 
Wood box (no top cover) quality requirements:
 
1. The middle column of the outer wooden strip of the wooden box 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, and the two nails are to be straightly inserted into the inner wooden strip of the frame;
 
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. The height of the bottom sleeper is not less than 60mm;
 
4. The bottom of the wooden box must be flat and strong.
 
Packing method: Calculate the inner diameter and width of the wooden box according to the number of layers installed on the side or the vertical. Each row and each layer should be placed in parallel and two 3mm thick thin strips are stuck to prevent bumping and unnecessary Missing corners. The slate at the time of packing must be complete with 4 corners.
 
Damage during transportation:
 
If the damage, corners and bumps caused by the transportation to the buyer's warehouse are not more than 0.5%, they shall be borne by the buyer.
 
If the damage, corners and bumps caused by the transportation to the buyer's warehouse exceed 1%, the two parties should negotiate and find the cause of the damage to avoid subsequent damage.
 
Taro brush system:
 
1. The surface of the wooden box can be brushed on one side; the number of the wooden box, the size and the number of pieces are respectively printed on the outer horizontal strip from the left to the right;
 
2. Other signs required by the buyer can be painted on the skewed wood strip;
