  The following dryer manufacturers share with you how to prevent the dryer from rusting:
  1. 烘干机的许多部件都要焊接,用于老式焊接的材料经常断裂和腐蚀。对烘干机使用寿命和严重程度的影响。不锈钢与普通碳钢的区别在于导热性差,膨胀系数大,电阻高。这些特性限制了特殊焊接方法的使用。但这种钢具有较强的耐腐蚀性,不易断裂。
  1. Many parts of the dryer need to be welded. The materials used for old-fashioned welding often break and corrode. The influence on the service life and severity of the dryer. The difference between stainless steel and common carbon steel lies in its poor thermal conductivity, high expansion coefficient and high resistance. These characteristics limit the use of special welding methods. But this kind of steel has strong corrosion resistance and is not easy to fracture.
  2. 钝化、磷化。在烘干机的制造中,许多零件是由碳钢制成的。如果工作时间长,表面容易生锈,而且经常需要大量的手工清洗工作。钝化和磷化方法主要是通过电化学反应在金属表面形成致密的防锈膜。用这种方法,即使我们把设备放在潮湿的环境中,也不会引起生锈。而且,该方法简单,可以节省大量的人力物力,减少投资,是目前应用广泛的防腐方法。
  2. Passivation and phosphating. In the manufacture of dryers, many parts are made of carbon steel. If the working time is long, the surface is easy to rust, and often requires a lot of manual cleaning work. Passivation and phosphating methods are mainly to form a dense anti-rust film on the metal surface by electrochemical reaction. In this way, even if we put the equipment in a humid environment, it will not cause rust. Moreover, this method is simple, can save a lot of manpower and material resources, reduce investment, and is the most widely used anti-corrosion method at present.
  3. Electrostatic powder spraying. Electrostatic powder coating is a new kind of powder coating for dryer drum. We usually use cold-rolled stainless steel to make dryers. This kind of steel is expensive and its corrosion resistance is not strong when it is replaced by ordinary carbon steel. Electrostatic powder coatings have the same corrosion resistance as stainless steel. We can completely replace stainless steel with ordinary carbon steel. In addition, the powder coating has the characteristics of good toughness, durability and decoration.
  Air dryer is a mechanical device that evaporates and evaporates water from materials (usually water or other volatile liquid components) to obtain specific moisture from solid materials. The use of an air dryer is described in detail below.
  In the mid-19th century, the use of dryers marked the development of dryers from intermittent operation to continuous operation. The drum dryer can realize the mixing, drying and strength of particulate matter. Some industries have developed continuous air dryers to meet industry requirements, such as drum air dryers in textile and paper industries.
  The purpose of drying is to use materials or require further processing. For example, drying wood before making moulds and wood can prevent deformation of products, and drying ceramic billets before calcination can prevent cracking of finished products. In addition, drying materials are also easy to transport and store, such as harvested grains dried to a certain moisture content to prevent mildew. As natural drying is far from meeting the needs of production development, various mechanical air dryers have been more and more widely used.
  In order to save energy, some materials with high water content, suspensions or solutions containing solid substances, are usually dehydrated or evaporated by mechanical heating, and then dried in an air dryer to obtain dry solids.
