What new trend of home appliance coating?

Now, home appliance enterprises mainly adopts two ways to make metal surface resistant to corrosion.

• anti-rust color-coated sheet
• Finish treatment on galvanized sheet or metal plate

Some appliance enterprises built their own coating finish line with low cost and good technology. They pay much attention to market change and tech development of appliance finish.


Pretreatment material- Phosphorized Liquid 

Most metal parts of home appliances have high requirements for corrosion. One common solution is phosphating in coating pretreatment. It’s a kind of chemical conversion from phosphorized Liquid to phosphate film, referred to as phosphating. The film and powder coating protect the metal surface from rust for a long time.

As we know, phosphating process is highly toxic. The nitrite and heavy metal pollution to the environment is terrible. So in recent years, many companies are developing alternative environmental metal finish pretreatment technology for phosphating.


Green pretreatment tech 

Among alternatives, the silane technology has good industrial application after years of development. It can meet the using demand of the automobile, household appliances and other industries. Besides, BonderiteNT-1 is also used in appliances, office furniture and hardware, etc. They both are not only featured with safety and environmental protection, but also can be operated at room temperature, saving energy and reducing consumption.

As for prices, the comprehensive cost of the two technology is lower than the phosphate process as well as equipment investment. Thus, more and more finish enterprises tend to provide green coating products of high quality and low cost for whole machinery factories.


Powder coating technology

After metal surface pretreatment, home appliances are always be powder coated on metal surfaces. Without volatile organic compounds (VOC), the cost-effective powder coating accord with environmental protection requirements, very suitable for application in the refrigerator, air conditioner, washing machine, microwave ovens and other electrical appliances production process. Among coating materials, epoxy polyester, mainly made from epoxy resin and polyester resin, is the most popular material is most widely used in home appliances.

As house appliance industry is booming, China powder coating sales rises about 10 percent than last year. Domestic coating has the advantage of comprehensive cost. First, some chinese finish suppliers tend to save raw materials by reducing coating film thickness and enhance spraying efficiency; low-temperature curing is also used, which can reduce power consumption in coating; the rest spraying powder of the appliances can be recycled. The overall process is done with advanced powder coating line for low coast and high efficiency.

From the above analysis, we can come to the conclusion that coating powder tends to grow environmental friendly and cost saving.

Finish Choose Guide Between powder coating and paint spray

In recent years, powder coating is applied to more and more industrial items, from bicycles, home furniture and office furniture, to kitchen appliances and automobiles. It has better performance on lifetime and attractive finish have than paint coating. What’s more, some powder types have not only common decoration and protection quality, but also with other protective features, such as ultra-violet rays, anti-corrosion, anti-abrasion and so on. Thus, some new consumers tend to choose powder coating.

powder Vs paint 

Generally, it has some advantageous features over paint coating from coating performance, energy consumption to environmental benefits.


Better coating performance

The unique features on powder coating line work make it with better performance on finish consistency and uniformity that that of painting coating. The powder spray work are less likely to have such defects as sags, drips, and bubbles. The finish is always regarded as super tough and durable, which can add value to target substrate with better impact resistance, corrosion resistance and flexibility.
Originally, such technology is designed to create coated products that can resist cracking, peeling and marring in normal use. In fact, the original design dream comes true to some extent, though the powder coating production line needs further improvement.


Energy saving

Compared with liquid painting system, the production process save about half energy from the efficiency whole powder coating line including automatic curing oven. The energy saving means not only fewer expense on no labor, material, waste disposal, but also higher efficiency. Thus, powder spray line develops fast in coating industry. It’s no doubt why both manufacturers and consumers prefer superior quality coating products with lower cost.


Environmental protection

To some extent, paint coating has some side effect on environment. The coating material contains some solvents that can make air pollution; sometimes, it burns the ozone layer; the painting line processes also release some sort of sludge. There seems no other good solution for the sludge rather than dumping into ground.


In contrast, powder coating has no chemical solvents and does not discharge a great amount of volatile organic compounds amounts to the air. So powder is quite different from liquid paints in this aspect.

Though powder over-spray may do harm to the air, it can be resolved by recycling use and the harm degree would be dismissed greatly.

All in all, people put much focus on energy saving and environment protection. All these advantages makes powder coating line become new favorite in finish industry.
