Solar panel glass coating ink

When talking about glass inks, many friends may think of the most common industries that use glass inks nowadays, such as touch-screen glass, household appliances glass, glassware, decorative glass and so on. Many people will not associate ink with solar glass. In fact, our company has been studying Solar Panel glass ink for two years. The quality of ink has been very mature.

In the past, when people were making glass inks, quality was only considered when considering adhesion, recoatability, leveling, hiding power, and printability. This made resistance to variability easy. The glass ink used on the solar panel glass, in addition to the above simple basic issues, there are more, higher, more complex performance requirements.

First of all, the solar panel glass is not an ordinary glass, but a layer of electro-aluminum or nickel glass is coated on the glass surface. The ink is printed on the surface of the coating, and the oil is not required to have any acidity or alkalinity, otherwise it will corrode. Plating.

Secondly, the ink on the solar panel glass is not a sign or decoration but has its special function: to protect the function of the coating, and to promote the conversion of energy to prevent the loss of energy.

Therefore, when developing solar panel glass inks, it cannot be considered based on the performance of ordinary glass inks. In terms of leveling, one-thousandth of a silicone antifoam leveler can cause problems. Because the four corners of the product will be glued when installed, silicone defoamers or leveling agents will not be strong enough to affect the quality of the board. In terms of water resistance, the vast majority of glass inks manufactured by companies today require only cold-water blisters for one day or hot water for two hours, and cook for four hours at most. And our ink requires one hundred days of boiled water to boil for 72 hours without discoloration and falling off. In the aspect of acid and alkali resistance, the requirements are even higher. It is required to soak in five percent of the ** solution for five hours without any abnormality, and soak in the sodium hydroxide (alkali) at fiveteen percent for five hours without discoloration. , degreasing, foaming, printed products will go through three months of outdoor testing. In terms of printability, according to the requirements of the production line, after the ink is scraped off, no oil is returned. The screen is exposed to the air for three minutes and a piece of glass is printed. The length of the glass is one meter two and the width is sixty centimeters. At one point, many suppliers are discouraged.

With the national energy conservation and emission reduction, and the gradual promotion of environmental protection policies, the solar photovoltaic industry as a national key energy-saving and emission reduction industry has received strong support from the country's policies. The industry has been growing rapidly, and the company’s solar panel glass ink is The leading companies in this industry have been widely used and the prospects are very promising. We are also proud to be able to contribute to the country's energy conservation, emission reduction and environmental protection.
