1、清洗

1. Cleaning

应用溶剂、乳剂清洗钢材外表,以到达去除油、油脂、灰尘、光滑剂和相似的有机物,但它不能去除钢材外表的锈、氧化皮(氧化作用而构成的腐蚀产物)、焊药等,因而在防腐消费中只作为辅助手腕。

Solvents and emulsifiers are used to clean the steel surface to remove oil, grease, dust, smoothing agent and similar organic matter, but they can not remove rust, oxide scale (corrosion products formed by oxidation), welding flux, etc. on the steel surface, so they are only used as auxiliary wrist in anticorrosive consumption.

2、工具除锈

2. Tool Rust Removal

主要运用钢丝刷等工具对钢材外表停止打磨,能够去除(qùchú)松动或翘起的氧化(oxidation)皮、铁锈、焊渣等。手开工具除锈能到达Sa2级,动力工具除锈可到达Sa3级,若钢材外表附着结实的氧化铁(Fe?O?)皮,工具除锈效果不理想,达不到防腐施工请求的锚纹深度。

Mainly use steel brushes and other tools to stop grinding steel appearance, can remove (qch) loose or warped oxidation skin, rust, welding slag and so on. Rust removal of hand tools can reach Sa2 level, power tools can reach Sa3 level. If the steel surface is adhered to strong iron oxide (Fe?O?) skin, the effect of tool rust removal is not ideal, and the depth of anchor lines required for anti-corrosion construction can not be reached.

3、酸洗

3. pickling

普通用化学(Chemistry)和电解两种办法(method)做酸(Acerbity)洗处置,管道(Conduit)防腐只采用化学酸洗,能够去除(qùchú)氧化(oxidation)皮、铁锈、旧涂层,有时可用其作为喷砂除锈后的再处置。化学清洗固然能使外表到达一定的清洁度和粗糙度,但其锚纹浅,而且易对环境形成污染(pollute)。

Chemical (Chemistry) and electrolysis (method) are commonly used for acid cleaning. Conduit corrosion protection only uses chemical acid cleaning, which can remove (qch) oxidation coatings, rust and old coatings. Sometimes it can be used as re-disposal after sandblasting and rust removal. Chemical cleaning can make the appearance reach a certain degree of cleanliness and roughness, but its anchor lines are shallow, and it is easy to pollute the environment.

4、喷(抛)射除锈

4. Rust Removal by Spraying (Throwing) Shooting

喷(抛)射除锈是经过大功率电机带动喷(抛)射叶片高速旋转,使钢砂、钢丸、铁丝段、矿物质等磨料在向心力作用(role)下对钢管外表停止喷(抛)射处置,不只能够彻底肃清铁锈、氧化(oxidation)物和污物,而且钢管在磨料猛烈冲击和磨擦力的作用下,还能到达所需求的平均(jūn yún)粗糙度。无缝钢管具有中空截面,大量用作保送流体的管道,如保送石油、自然气、煤气、水及某些固体物料的管道等。钢管与圆钢等实心钢材相比,在抗弯抗扭强度相同时,重量较轻,是一种经济截面钢材。

Rust removal by spraying (throwing) is a process of high-speed rotation of spraying (throwing) blades driven by high-power motors, which enables abrasives such as steel sand, steel balls, wire segments and minerals to stop spraying (throwing) on the surface of steel pipes under centripetal force (role). It can not only thoroughly remove rust, oxidation and dirt, but also steel pipes are impacted and polluted by abrasives. Under the action of friction force, the required average roughness (jn yn) can also be achieved. Seamless steel tube has hollow section, which is widely used as a pipeline to deliver fluids, such as oil, natural gas, gas, water and some solid materials. Compared with solid steel such as round steel, steel pipe has lighter weight when its bending and torsional strength is the same. It is a kind of steel with economic section.
