Metalizing Wire | Metalizing Wire Manufacturer in India

From: sand blasting hopper

The metalizing wire used in the thermal spray gun for the coating process. Coating provides over the substrate with a different method. Thermal spraying is done to increase the life of the substrate and prevent it from corrosion in even the hardest condition. The selection of metalizing wire in the thermal spray is based on the application of the substrate on which coating to be done. Metalizing wires are used in pure form as well as in alloy form also.



Types of metalizing wire

Zinc wire

Zinc Wire is present in a variety of diameter and mostly used in small, voids and uncoated areas which are not readily accessible. Zinc wire coating has more resistance in hard water and less in soft water. Zinc wire is mostly used in pH range 6 to 12. Zinc coating has poor resistance in any water above 60 degrees Celsius. Zinc wire coating has poor resistance to almost all organic and inorganic acids. Zinc is mostly used as a primer on surfaces to form electrically conductive surfaces on glass and ceramics. Zinc wire also used in alloy form depends upon the application.

Applications

  • Atmospheric and immersion corrosion protection on large steel or iron structures like bridges, roadway barriers, posts and poles, offshore structures, and marine structures.
  • Corrosion protection on steel or iron substrate such as tanks and gas bottles.

Aluminum wire

Aluminum wire is used in the coating process and drawn to a variety of diameters for use in a flame spray gun and arc spray gun system. Aluminum wire has useful characteristics that include resistance to the atmosphere, chemical, and heat corrosion. Aluminum wires are good electrical conductors. Aluminum wire coating tends to form an oxide film that protects it from further attack.

Aluminum wire coatings used for cathodic corrosion protection in atmospheric and salt/freshwater immersion, with application areas such as oil refining equipment, chemical processing equipment, boat bottom interiors exposed to bilge water, and other similar types of exposure. It increases the life of the substrate by 15-50 years without maintenance.

Applications

  • General industry: Cathodic corrosion protection coating on steel structures such as bridges and water towers in which the coating can be used alone and a  very good bond and protective undercoat for organic materials.
  • Aviation: to provide coatings on fiberglass panels for static dispersion and corrosion protection of outer casings.
  • Automotive: coating on high-temperature corrosion protection on exhaust valves.
  • Electronics: coating over an electrical conductance on components such as conductive areas on insulators, capacitor end caps, and varistors.

Shot Blasting Machine | Shot Blasting Machine Price in India

Image
From: sand blasting hopper Shot Blasting Machine   is used as a mechanical method for the surface treatment by using an abrasive with the help of a centrifugal wheel at high speed to obtain excellent surface and remove impurities for secondary operations. Shot blasting is used for the following main purposes: It provides a better texture to enhance paint adhesion. It increases the coating life of a machine by reducing its maintenance cost. For cleaning and preparing the surface before painting, coating, metalworking. It also used for making non-slipping surfaces and providing surface homogenization. Shot blasting is done after heat treatment and also for mechanic descaling. The shot blasting is done in two ways: Wheel blasting: It is a common and economical method. In this process, the electric motor energy is converted into kinetic energy by rotating a turbine wheel. This is mostly used for treating heavy equipment. The turbine wheel works here as a centrifugal pump and it deliver...

Thermal Spray Gun   is used for coating processes in which melted materials are sprayed on the surface to provide better polishing and remove foreign particles. Thermal spray guns provide thick coatings up to several mm depending on the application.   Thermal Coating   materials available for thermal spraying include metals, alloys, ceramics, plastics abrasives, and composites. The coal thermal spray guns are used for coating processes in which melted materials are sprayed on the surface to provide better polishing and remove foreign particles. Thermal spray guns  are used to improve the metal surface. The main purpose of using a thermal spray gun is the expand the rotating shaft and increasing the life of the  sand blasting machine . The thermal spraying method can come up with a thick coating over a large area at a high deceleration rate as compared to more coating processes. The thermal spray gun melts the material which results in molten droplets accelerated...

 From: sand blasting hopper Sand blasting Machine A  Sand Blasting machine  is mainly used to remove rust, corrosion, and contaminants from the metal surface with the help of abrasive media. In the sand blasting machine, silica sand is used as an abrasive for sand blasting operation. A  Sand blasting machine  is also used to mold and to clean the surface of the metal. For this blasting process, compressed air at high velocity and pressure is imparted on the blast wheel. The sand blasting machine is the strongest method among all the other blasting methods.  Types of Sand blasting machine Pressure blasting machine Suction blasting machine Wet blasting machine Working of Sand blasting machine In the sand blasting machines, compressed air with abrasive is used for surface preparation. It is one of the most efficient and fast methods of blasting.  The sand blasting machine involves the operation of forcibly propelling a stream of abrasive material against ...
