1. Cold sprayed zinc guardrail: cold sprayed zinc is to hang the guardrail , which has also been degreased and derusted, showing no dirt and infiltration, into the cathode of the special electroplating bath, and the anode is zinc. When the DC power supply is connected, the zinc ions on the anode migrate to the cathode and discharge on the cathode, so that the guardrail plate workpiece is coated with a layer of zinc.
2. Hot-dip galvanized guardrail : hot-dip galvanized, also known as hot-dip galvanized, is to remove the oil and rust of the guardrail board work, showing a non-fouling and wetted surface, immediately immersed in the pre-heated zinc melt In the plating tank, a method of forming a layer of zinc coating on the surface of the guardrail .
3. Plastic spray guardrail: Spray plastic is the electrostatic powder spray we often talk about. It uses an electrostatic generator to charge the plastic powder. Plastic powder is powder coating, which is a new type of solvent-free 100% solid powder coating. It has two major categories: thermoplastic powder coatings and thermosetting powder coatings. The coating is made of special resin, pigment and filler, curing agent and other auxiliary agents, mixed in a certain proportion, and then prepared by hot extrusion molding, crushing and sieving and other processes. They are stable at room temperature, electrostatically sprayed or fluidized bed dip-coated, then heated, baked, melted and solidified to form a flat and bright permanent coating film for decorative and anti-corrosion purposes. Commonly used in: shelves, cabinets, workbenches, logistics storage and transportation equipment, etc.
4. Paint spraying: paint spraying is a method of spreading into uniform and fine mist droplets by means of air pressure with a spray gun and applying it to the surface of the object to be coated. Water and oil resistant, fast drying, used to paint cars, aircraft, wood, leather, etc. The substance is toxic and has a certain effect on the body. Different brands of spray paint have different toxicity due to the different content of the ingredients. Special care should be taken when using it to avoid inhalation and skin contact.
