表面處理
surface treatment
1．亮鉻：像鏡面一樣的光亮；
1. Bright chrome: as bright as a mirror;
2．亞鉻：無(wú)光澤；
2. Chromite: no luster;
3．電泳：黑色，有亮度，在外加直流電的作用下，使帶電粒子在分散的介質(zhì)力向陰極或者陽(yáng)極做定向移動(dòng)，促使物質(zhì)的分離；
3. Electrophoresis: black, bright, under the action of external direct current, the charged particles move to the cathode or anode in the dispersed medium force, promoting the separation of substances;
4．磷化：黑色，但光澤暗，把物質(zhì)浸在磷化液中，在便面沉積形成一層不溶于水的結(jié)晶型磷，是鹽酸轉(zhuǎn)換的過(guò)程。
4. Phosphating: black, but with dark luster, the substance is immersed in the phosphating solution and deposited on the surface to form a layer of crystalline phosphorus insoluble in water, which is the process of hydrochloric acid conversion.
5．灰鎳：是一種全新的表面處理方式，防銹能力強(qiáng)，且會(huì)增加產(chǎn)品的使用年限。
5. Gray nickel: it is a new surface treatment method, with strong anti rust ability, and will increase the service life of the product.
6.其他還有發(fā)黑，鎳鐵合金，珍珠鎳，黑鎳和鍍鈦等處理

6. Other treatments include blackening, ferronickel, pearl nickel, black nickel and titanium plating
檢測(cè)要求
Testing requirements
1．不得有生銹，毛刺，裂紋和斑點(diǎn)等；
1. No rust, burr, crack, spot, etc;
2．扳口對(duì)稱(chēng)，激光刻字要清楚；
2. The opening should be symmetrical and the laser engraving should be clear;
3．硬度要達(dá)到規(guī)定標(biāo)準(zhǔn)，且卡位要準(zhǔn)確；
3. The hardness shall reach the specified standard and the clamping position shall be accurate;
4．活絡(luò)扳手的渦輪運(yùn)作要靈活，銷(xiāo)軸不能松動(dòng)；
4. The turbine operation of the adjustable wrench should be flexible, and the pin shaft should not be loose;
扳手的正確使用與保養(yǎng)
Correct use and maintenance of spanner
1.使用前，應(yīng)根據(jù)被扭件規(guī)格及所在位置大大小，選擇符合規(guī)格的扳手
1. Before use, the wrench that meets the specification should be selected according to the size of the twisted part and its position
2.扭動(dòng)手柄時(shí)用力要平穩(wěn)，用力方向與被扭件的軸線(xiàn)垂直。
2. When twisting the handle, the force should be stable, and the direction of force should be perpendicular to the central axis of the twisted part.
3.使用扳手時(shí)，更好是拉動(dòng)而不是推動(dòng)，拉力的方向要與扳手的手柄成直角。
3. When using the wrench, it is better to pull rather than push, and the direction of pulling force should be at right angles to the handle of the wrench.
4.非推時(shí)，要用手掌推，手指伸開(kāi)，防止撞傷關(guān)節(jié)。
4. When not pushing, push with palm and extend fingers to prevent joint injury.
