There are all kinds of furniture in life, such as: bed, nightstand, dresser, dining table, dining chair, wine cabinet, sofa, coffee table, small bench and so on. They have different inspection standards and different inspection methods. Today Xiaobian to introduce the small bench appearance inspection projects and inspection standards.
1. Size inspection: The allowable error between the sample size and the measured value of the inspected product is ±5mm
Ii. Size standard (i.e. functional size) (mm)
Chair stool chair height 400,420,440; Armrest inner width ≥460
Three, foot stability (mm) Standard foot landing stability ≤2
Four, flatness (mm) standard panel, face panel parts ≤0.2
Five, adjacent verticality (mm) standard panel diagonal length ≤2.5
Diagonal length of frame ≥1000 allowed value ≤3; Diagonal length < 1000 allows value ≤2
Vi. Material inspection
(1) The texture of the tree species used in a single or complete set of products should be similar, and there should be no obvious difference in the tree species of the same rubber piecework. Needles and broadleaf materials should not be mixed.
② Moth-eaten wood must be treated with insecticides, and the wood that insects continue to erode shall not be used.
The visible parts shall not use rotten materials, internal or closed parts of the material is slight
The rotten area shall not exceed 15% of the part area, and the depth shall not exceed 25% of the material thickness.
④ The appearance and storage parts of the material shall not have resin sac.
⑤ The twill degree of the stress part of the product is more than 20% shall not be used.
⑥ the width of the segment does not exceed one third of the width of the visible material, the diameter does not exceed 12mm, after repair processing does not affect the strength of the product structure and appearance can be used.
⑦ Other slight material defects, such as cracks (except through cracks), blunt edges, etc., should be repaired, do not affect the strength of the product structure and appearance can be used.
⑧ Wood moisture content should not be higher than the local average annual wood balance moisture content plus 1%.
Seven, woodworking inspection
① No broken tenon is allowed at the joint of the tenon.
The combination of tenon and parts should be tight and firm.
The installation of various accessories shall not have fewer pieces, leakage nails, nails through.
(4) The qualification coefficient is 0.7. The installation of all kinds of accessories should be tight, smooth, correct and firm, and the joint should be free from breakage or loosening. The appearance of shuttles, rounded corners, round lines should be uniform. Roughness of uncoated parts: internal Ra3.2~12.5μm (fine light); Ra > 12.5μm (coarse light) at the notch.
Eight, finish inspection
① The color of the whole product or complete set of products should be similar.
② The surface of the product shall not have wrinkled skin, sticky and paint leakage phenomenon.
③ The parts of the product should be kept clean.
④ The qualification coefficient is 0.7. The surface coating (including the panel) should be smooth and clear. There should be no obvious wood hole subsidence after the film is dried. Other parts of the coating hand induction smooth, no obvious particles. After the film is dry, allow wood hole subsidence, allow a small edge and uneven. The coating shall have no obvious processing marks, scratches, white spots, bubbling, flow hanging, shrinkage, and impurities.
