Surface treatment is the technique of creating an odd layer on the base intentionally, and it stands out in mechanical, physical, and chemical properties different from the base material.

The overall working performance of the Bathtub drain is closely related to its surface property, and the surface performance cannot be achieved merely by the base material; thereby, the surface treatment technology is needed to make the drain more resistant to corrosion and wear.

Overall, surface treatment for the Bathtub drain is to improve appearance, enhance texture, optimize function, etc.

For the metal base, commonly used surface treatment methods are

  • Electrophoresis,
  • Acid pickling,
  • Wire drawing,
  • Powder coating,
  • Vacuum Plating,
  • electroplating,
  • Sand Blasting

Electrophoresis surface treatment for bathtub drain

Electrophoresis is a process that can coat the surface of stainless steel or aluminum alloy with a thin layer of insoluble material. Under an electric field, charged particles are attracted to opposite electrodes and deposit on the surface of the workpiece. This process can be used to create a variety of colors and finishes on the metal surface.

Plating data

This finish is often used on bathtub drains because it is durable and resistant to corrosion. The electrophoresis process creates a smooth, uniform surface that is easy to clean and maintain. In addition, this finish is available in a wide range of colors, allowing you to choose a drain that matches your bathroom décor.

Electrophoresis may be the perfect option if you want a durable and attractive way to finish your bathtub drain. This cost-effective process can help create a unique look for your bathroom that will last for years.

Acid Pickling surface treatment for bathtub drain

Acid pickling uses an acid solution to remove oxides and rust from the surface of a base material, such as steel. The oxide reacts with the acid to form salts dissolved in the acid solution. This makes it an excellent treatment for preventing rust. It can also be used as a pre-or intermediate treatment in processes such as electroplating.

acid solutions

Acid pickling is typically done using hydrochloric or sulfuric acid, although other acids can be used. The concentration of the acid solution and the treatment time will vary depending on the type of metal being treated.

Acid pickling is an effective way to remove rust and oxides from metal surfaces. Additionally, it can be used as a pretreatment in procedures like electroplating.

Wire Drawing surface treatment for bathtub drain

Wire drawing is a surface treatment for bathtub drains that creates a textured, matte finish. This finish is achieved by pulling a wire brush or other abrasive tool over the surface of the metal. The wire brush removes a small amount of metal, revealing a new layer of metal below. This new layer is typically darker in color and has a rougher texture than the surrounding metal. The wire drawing process can be repeated multiple times to create a more pronounced effect.

The advantages of wire drawing surface treatment for bathtub drain is as follows:

  • It can create a unique, stylish look for your bathtub drain.
  • This surface treatment can also help to hide scratches and other imperfections.
  • Wire drawing is a relatively simple and inexpensive process.

Powder Coating surface treatment for bathtub drain

Powder coating for bathtub drain takes advantage of the electric discharge phenomena of the corona to make plastic powder adsorb on the metal workpiece. As a result of corona discharge, a dense charge is generated in its vicinity. This dense charge accelerates the movement of electrons and causes them to collide with gas molecules, resulting in the ionization of gas molecules. The ions produced are attracted to the workpiece and form a conducting path between the electrode and the workpiece. When the voltage is applied to the workpiece, an electric field is generated around the workpiece, which causes the powder particles to be attracted to the workpiece. The powder particles are deposited on the surface of the workpiece and form a uniform coating. A powder coating surface treatment can enhance the bathtub drain’s longevity and attractiveness.

Powder coating is a method of applying plastic powder to a metal surface using an electric charge. The powder is then baked to create a solid surface. Compared to typical wet painting, powder coating provides some benefits, including excellent color retention, enhanced resistance to wear and tear, and improved longevity. Powder-coating with proper procedures can also offer excellent corrosion resistance and environmental durability.

Advantages of Powder Coating surface treatment for bathtub drain

The benefits of powder coating surface treatment for bathtub drain are as follows:

  • It can improve the appearance and durability of the bathtub drain.
  • Several benefits of powder coating versus wet painting include excellent color retention, enhanced resistance to wear and tear, and improved longevity.
  • Powder-coating with proper procedures can also offer excellent corrosion resistance and environmental durability.

Vacuum Plating surface treatment for bathtub drain

Vacuum Plating surface treatment for bathtub drain is a process that realizes the transfer of substances through physical reaction. Its function enables the base material to obtain better properties, including high strength, wear resistance, heat dissipation, corrosion resistance, etc. In addition, PVD can make various colors, such as gun color, gray, and champagne. Due to the complicated process, PVD relies heavily on manual operation.

colors after coating

The PVD process starts with cleaning the bathtub drain’s surface. To obtain good adhesion of the coating on the surface of the substrate during sputtering, it is necessary to perform a degreasing process on the surface of the substrate to remove oil and grease. The next step is to sputter a vacuum in an inert gas atmosphere. After deposition, PVD can provide a bright and lustrous finish resistant to tarnishing and corrosion.

Vacuum plating is an environmentally friendly surface treatment technology that does not produce wastewater or pollution during operation. Therefore, it is widely used in various fields such as hardware products, watches, glasses, molds, etc. As science and technology advance constantly and people’s aesthetic needs, the application of PVD technology will become more widespread.

Electroplating surface treatment for bathtub drain

The most common surface treatment process is electroplating, which uses electrolysis to deposit metal or alloy on the surface of the workpiece, forming a uniform and dense metal layer.

This surface treatment attaches a metal film to the metal surface to improve its corrosion resistance and wear resistance while at the same time giving it a high glossy finish.

Under normal circumstances, electroplating does not require a heat source, and various coatings can be performed at an average temperature of 15-40°C.

The plating layer and the base material form an alloy that significantly enhances the product’s strength.

Colors change after coating.

This process is often used to protect surfaces from corrosion or wear and tear, such as on bathtub drains.

An electroplated coating on a bathtub drain will significantly extend its lifespan by protecting it from corrosion and everyday wear and tear.

This will not only save you money in the long term, but it will also save time and work because you won’t need to repair your drain as frequently.

Therefore, consider electroplating if you’re seeking a strategy to extend the life of your bathtub drain.
