螺丝除锈剂 Screw rust remover

黑色金属(钢材)置于室外或露天条件下容易生锈,不但影响外观质量,还会影响喷漆、粘接等工艺的正常进行，如不及时处理，更会造成材料的报废，导致不必要的经济损失[1]。传统的化学除锈通常使用强酸，酸能与铁锈及金属氧化物发生化学反应，生成可溶性盐类，从而达到除锈的目的，除锈的同时，酸又能和基础金属发生反应放出氢，氢能对铁锈和难溶的氧化皮产生压力，有利于他们的剥落和高价铁的还原，加速酸洗的过程，但传统的酸液处理方法也存在着明显的缺陷：即处理过程中大量氢气的产生会使钢材产生氢脆现象，引起金属的力学性能下降，影响钢铁本身的强度；同时易形成酸雾，影响操作人员的健康和腐蚀周围的设备及环境；酸液的消耗量也较大，增加处理成本；这类酸会对钢材形成过腐蚀。此外大量产生的残渣，需经常排放，既严重腐蚀工业管道，又污染土壤和环境。它可广泛应用于制造业、建筑业、修理业、交通、能源、电力、石油及矿山开采等多种行业，适用于机械设备、车辆、船舶、军械、五金工具、建筑模板、金属零配件等钢材的除锈．其优越的性能会给您带来意想不到的方便和实惠。

Black metal (steel) is easy to rust when placed outdoors or in the open air, which not only affects the appearance quality, but also affects the normal process such as painting and bonding. If not treated in time, it will cause the scrap of materials and unnecessary economic losses [1]. Traditional chemical cleaning often use strong acid, acid can react with rust and metal oxide, generate soluble salts, so as to achieve the purpose of cleaning, derusting, acid can react and base metal release hydrogen, hydrogen to rust and refractory oxide skin pressure, is good for their peeling and high iron reduction, accelerate the process of pickling, However, the traditional acid treatment method also has obvious defects: that is, the generation of a large amount of hydrogen in the process of treatment will cause the hydrogen embrittlement phenomenon of steel, resulting in the decline of the mechanical properties of metal, affecting the strength of steel itself; At the same time, it is easy to form acid fog, which affects the health of operators and corrodes the surrounding equipment and environment. The consumption of acid is also large, which increases the treatment cost. This kind of acid will overcorrode steel. In addition, the residue produced in large quantities needs to be discharged frequently, which not only seriously corrodes industrial pipelines, but also pollutes soil and environment. It can be widely used in manufacturing, construction, repair industry, transportation, energy, electricity, oil and mining and other industries, suitable for machinery and equipment, vehicles, ships, weapons, hardware tools, building template, metal parts and other steel rust removal. Its superior performance will bring you unexpected convenience and benefit.

螺丝除锈剂的使用方法如下：

The use of screw rust remover is as follows:

使用浸泡、涤刷或喷洒方式均可，浸泡方法效果明显。除锈后应用大量水冲洗其残留物，如果除锈后需防锈，则需应大量水冲洗后，用5%氢氧化钠溶液进行中和钝化、擦干后再喷洒防锈剂进行保护。

Use soaking, scrubbing or spraying method can be, soaking method has obvious effect. After rust removal, a large amount of water should be used to rinse the residue. If rust removal is needed for rust prevention, a large amount of water should be used to rinse, neutralize and passivation with 5% sodium hydroxide solution, and then spray rust prevention agent for protection after drying.

1、使用前需要将产品搅拌均匀，涂刷前清除钢铁表面疏松浮锈，破裂氧化皮，电焊渣泥土，油污物等。

1. Before use, the product needs to be stirred evenly, and the iron and steel surface needs to be removed before brushing, such as loose floating rust, broken oxide scale, welding slag soil, oil dirt, etc.

2、涂刷产品不同一般油漆涂刷，宜先横刷一道，接着竖刷一道，锈薄轻涂，锈厚重涂，不得漏涂。

2. Brushing products are different from general paint brushing. It is advisable to brush horizontally first, then brush vertically, paint lightly with thin rust, and coat with thick rust.

3、有明显刷痕及针孔等缺陷，要及时修补，若涂层出现白泡，应立即用棉纱擦掉，再用棉纱沾少量酒精轻擦一下，以减少表面残留的酸性物质，不致影响防锈质量。

3, there are obvious brush marks and pinholes and other defects, should be repaired in time, if the coating appears white bubble, should be immediately wiped off with cotton yarn, and then cotton yarn dipped in a small amount of alcohol to wipe gently, to reduce the residual acid on the surface, will not affect the quality of antirust.

4、将金属工件充分干燥后做防腐处理，保证工件不会生锈。

4, the metal workpiece fully dry after anti-corrosion treatment, to ensure that the workpiece will not rust.
