Wood products refer to products made of wood as raw materials, assembled with hardware accessories, painted and glued. Wood products are closely related to our lives, ranging from sofas in the living room to beds in the room, as small as the chopsticks we usually use for meals. , its quality and safety are concerned, and the inspection and testing of wood products are particularly important.近年、ワードローブ、椅子、屋内および屋外の植物ラックなどの中国から輸出された木製製品も、Amazonのeコマースプラットフォームなどの海外市場で非常に人気があります。 So how to inspect wood products? What are the standards and common defects of wood products inspection?

3. Inspection environment: the brightness of the ambient light should be 600-1000LUX, and the light source should be higher than the examiner's head; there should be no reflections around the environment; the distance between the human eye and the object to be measured should be kept at 40cm, and the angle of the object to be measured should be 40cm. 45° (写真)。

1. 目視検査

ａ． The front surface is flat, without unevenness, and without spikes. b. The other sides are flat, the color is uniform, there is no color difference with the front, no impurities, foam printing. c. The color difference between batches of the same type of product cannot exceed 5%, and there are no adverse phenomena such as exposed bottom, peeling, bubbles, sagging, pimples, orange peel, pitting, foam marks, impurities, etc. d. No defects such as bumps, excessive edges and corners, uniform thickness, no deformation. e. There shall be no more than 3 concave points of 3mm, and shall not gather within 10cm2;凹凸は許されません。

2. 製品のサイズ、厚さ、重量のテスト

3. 静荷重試験

Test method: Load a certain weight on the load-bearing parts of the tested product, such as chair seat, backrest, armrest, etc. The product should not be overturned, tipped, cracked, deformed, etc. After the test, it will機能的な使用には影響しません。

4. 安定性試験

椅子の安定性テスト

5. 振とうテスト

6.臭気試験

7. バーコードスキャンテスト

8. 衝撃試験

9. 湿度試験

Requirements for wood moisture content: When the moisture content of wood changes greatly, uneven internal stress occurs inside the wood, and major defects such as deformation, warpage, and cracking occur in the appearance of the wood.一般的に、江蘇省とZ江地域の固体木材の水分含有量は、次の基準に従って制御されます。固体木材材料の調製セクションは6〜8の間で制御され、加工セクションとアセンブリセクションは8〜10の間に制御されます。 3つの合板のうち6から12の間で制御され、マルチ層合板、粒子ボード、中密度ファイバーボードは6〜10の間で制御されます。一般製品の湿度は12未満で制御する必要があります。

Drop test is performed in accordance with ISTA 1A standard. According to the principle of one point, three sides and six sides, the product is dropped from a certain height for 10 times, and the product and packaging should be free of fatal and serious problems.このテストは主に、製品の取り扱い中に受ける可能性のある自由落下をシミュレートし、偶発的な衝撃に耐える製品の能力を検査するために使用されます。

For many wooden furniture, the products received by the final consumers are semi-finished products, which need to be installed by consumers themselves. When inspecting the goods, the inspectors need to distinguish materials, components, hardware, processes, specifications, instructions and other related accessories.マニュアルの手順に従って製品を完全にインストールすると、目的は、製品構造と製造精度が不十分かどうかを確認し、マニュアルの正しい操作を確認することです。

組み立て原理:緻密、平坦、しっかり、正確

組立一般検査基準：

組み立て要件：1. The reference standard for the diagonal length of the opposite side length error: ≥1000 ≤1.5 <1000 ≤1.0, for example: if the diagonal of the crib headboard and guardrail is generally within 1000mm – 1400mm, the diagonal length error should be 1.5mm以下に管理されています。 2. The warpage of the piece (panel), 700≤diagonal length<1400≤1.5, diagonal length<700≤1.0, for example: put the guardrail or the head of the bed on a horizontal reference plane, normally the four corners should be stable , if there is warpage on one or both sides, the range of this warpage should be controlled below 1.5mm. 3. 足の安定性 mm ≤ 1.5; for example: an assembled bed or furniture requires four feet to be parallel to the ground, but if there is warpage, the range should be controlled below 1.5mm. 4.隣接する側面垂直mmパネル斜め長さ≥1000≤1.5、<1000≤1.0は、組み立てられた家具と地面の四隅のたるみ、および斜角の比較によって得られる値を指します。

ａ． The parts made of wood-based panels have no edge-sealing treatment. Except for the large surface to be veneered or closed with paint, all the exposed parts of the cross-section are required to be closed. The sealing method can be painted or other materials. b.クラッディング材を貼り付けた後は、脱ガム、バブリング、継ぎ目、透明な接着剤が必要です。 c.部品の接合部、ほぞ穴接合部、板部品、各種サポート等に緩み、継ぎ目、破断がある。 The appearance of the product is uneven and asymmetric; the round lines and rounded corners of the product are uneven and asymmetric; e. There is asymmetric pattern and line shape after carving and turning wood processing, the bottom of the shovel is uneven, and there are knife marks and cracks;商品は外面未研磨、内面未研磨、ザラザラした部分には鋸毛や傷がございます。 2. The following defects are not allowed on the products after paint processing: a. The whole product or complete set of products has obvious color difference; the surface coating of the product is wrinkled, sticky and leaking paint; b. The paint film coating There are obvious fog, white corrugations, white spots, oily white, sagging, shrinkage holes, bristles, powder accumulation, miscellaneous residues, scratches, bubbling and peeling; c. There are depressions on the surface of soft and hard covering materials, Points, scratches, cracks, chipping and cutting edges; d.
