At the moment, home appliance businesses mainly adopts two methods to make metal surface resistant against corrosion.
anti-rust color-covered sheet
Finish treatment on galvanized sheet or metal plate
Some appliance businesses built their very own coating finish line with inexpensive and good technology. They pay much focus on market change and tech growth and development of appliance finish
Pretreatment material- Phosphorized Liquid
Most metal areas of home home appliances have high needs for corrosion. One common option would be phosphating in coating pretreatment. Its a type of chemical conversion from phosphorized Liquid to phosphate film, known to as phosphating. The video and powder coating safeguard the metal surface from rust for any lengthy time.
As you may know, phosphating process is extremely toxic. The nitrite and high metal pollution towards the atmosphere is terrible. So recently, a lot of companies are developing alternative ecological metal finish pretreatment technology for phosphating.
Eco-friendly pretreatment tech
Among options, the silane technologies have good industrial application after many years of development. It may satisfy the using need for the car, household home appliances along with other industries. Besides, BonderiteNT-1 can also be utilized in home appliances, business furniture and hardware, etc. Both of them are not only seen featured keeping the vehicle safe and ecological protection, but is also operated at 70 degrees, saving energy and reducing consumption.
For prices, the excellent cost of these two technologies are less than the phosphate process in addition to equipment investment. Thus, increasingly more finish businesses have a tendency to provide eco-friendly coating items of top quality and occasional cost for whole machinery industrial facilities.
Powder coating technology
After metal surface pretreatment, home home appliances will always be be powder covered on metal surfaces. Without chemical toxins (VOC), the price-effective powder coating accord with ecological protection needs, very appropriate for application within the refrigerator, ac, washer, microwaves along with other electrical home appliances production process. Among coating materials, epoxy polyester, mainly produced from epoxy resin and polyester resin, is easily the most popular materials are most broadly utilized in home home appliances.
As house appliance market is booming, China powder coating sales increases about 10 % than this past year. Domestic coating has the benefit of comprehensive cost. First, some chinese finish providers have a tendency to save recycleables by reduction of coating film thickness and enhance squirting efficiency low-temperature curing can also be used, which could reduce power consumption in coating the relaxation squirting powder from the home appliances could be recycled. The general process is completed with advanced powder coating line for low coast and efficiency.
In the above analysisPsychology Articles, we are able to arrived at the final outcome that coating powder has a tendency to grow ecological friendly and price saving.
