    模具钢放置时间长了,模具钢的表面多多少少会有一些生锈,那么在模具生产中,不仅仅会加大人工成本,还会影响产品的质量,处理这些问题非常的麻烦,所以很多人想问,模具钢该如何防锈,防锈有什么技巧和方法?下面济南模具钢厂家小编告诉大家。
    Mold steel placed for a long time, mold steel surface more or less there will be some rust, so in mold production, not only will increase labor costs, but also affect the quality of products, deal with these problems is very troublesome, so many people want to ask, mold steel how to rust, rust what skills and methods? Below Jinan die steel manufacturers Xiaobian tell you.

    模具在投入生产之前如果出现生锈,首先我们用角磨机装上钢丝刷子轮片去打磨,这种方法是普通的也是简单的,打磨之后清扫干净然后再涂抺下防锈油,预防再次氧化生锈。
    If there is rust in the mould before it is put into production, first of all, we use the angle grinder to install the steel wire brush wheel to polish it. This method is common and simple. After polishing, clean it up, and then apply anti rust oil to prevent it from oxidation and rust again.
    使用激光除锈机除锈,激光除锈机是目前工具,也除锈干净,但购置价格比较昂贵,一般用在专业的行业里使用。除锈后再涂抺上防锈油。
    Use laser derusting machine to remove rust, laser derusting machine is the current tool, also clean, but the purchase price is more expensive, generally used in the professional industry. After rust removal, apply antirust oil.
    还有一种是使用除锈剂,使用除锈剂除掉锈迹之后再使用清洗剂把表面的除锈剂清洗掉,再涂抺上防锈剂。市场上用的除锈剂是用稀硫酸和盐酸配制而成,但这种除锈剂的缺点就是除锈一二小时之后模具表面又会氧化生锈。这是因为除锈剂除锈后模具表面会残留部分硫酸和盐酸跟模具产生化学反应,形成新的锈迹。建议大家不要使用这种含有硫酸和盐酸的除锈剂。
    Another is the use of rust remover. After rust is removed by rust remover, the surface is cleaned by cleaning agent, and then coated with rust inhibitor. The rust remover used in the market is made of dilute sulfuric acid and hydrochloric acid, but the disadvantage of this rust remover is that the mold surface will be oxidized and rusted after one or two hours of rust removal. This is because some sulfuric acid and hydrochloric acid will remain on the surface of the mold after rust removal, which will react with the mold to form new rust. It is recommended that you do not use this rust remover containing sulfuric acid and hydrochloric acid.
    耐候钢:耐腐蚀性能优于一般结构用钢的钢材称为耐候钢,一般含有磷、铜、镍、铬、钛等金属,使金属表面形成保护层,以提高耐腐蚀性。
    Weathering steel: steel with better corrosion resistance than general structural steel is called weathering steel, which generally contains phosphorus, copper, nickel, chromium, titanium and other metals to form a protective layer on the metal surface to improve corrosion resistance.
    热浸锌:热浸锌是将除锈后的钢构件浸入600℃左右高温融化的锌液中,使钢构件表面附着锌层,锌层厚度对5mm以下薄板不得小于65μm,对厚板不小于86μm。从而起到防腐蚀的目的。
    Hot dip galvanizing: hot dip galvanizing is to immerse the steel member after rust removal into molten zinc at about 600 ℃ to make the surface of steel member adhere zinc layer. The thickness of zinc layer shall not be less than 65 μ m for thin plate below 5mm, and not less than 86 μ m for thick plate. So as to play the purpose of anti-corrosion.
