Vigorous development of automatic glass cutting machine
printing, make corresponding development of a new type of network printing ink is also very fast, such as fragrance of ink, fluorescent ink, foam ink, fast curing ink.
The ink is usually dry at room temperature only glass ceramic raw piece of printing and drying at higher temperature.
So often refers to the high temperature glass and ceramic printing ink printing ink.
Depending on the different substrate and the temperature of the printing ink, thermal requirement of temperature is different.
Automatic glass cutting machine by two inorganic glass screen printing ink, inorganic pigments, after grinding, to a certain fineness, add acrylic ester, screen printing on glass surface, high temperature (
More than 600 ℃)
Roasting 1 ~ 2 minutes, and ink layer surface of glass melting together, good fastness.
Ink over heat temperature of 600 ℃.
But as a result of such a big screen printing process, the cost of technology is more complex, rarely use the screen printing industry.
The other is a low molecular compound is inorganic binder glass cutting machine.
Amine and epoxy need baking, screen printing ink are widely used in the domestic market, bake for 30 minutes after the 1300 ~ 1400 ℃, ink temperature is lower, but no longer baking time.
Automatic glass cutting machine ink layer fastness and excellent hardness, brightness is very good also, low concentration of electrolyte and ethanol, acetone, benzene, cyclohexanone solvent corrosion ability.
Automatic glass cutting machine according to the calcination temperature ceramic printing method can be divided into two kinds: one kind is early in the 700 ~ 800 ℃ under the temperature of the biscuit firing, after the biscuit firing glaze, then firing on the temperature of 1100 ~ 1300 ℃.
In 1100 ~ 1300 ℃ need the ink used in the model of heat-resisting temperature, another is in the high temperature at 1100 ~ 1250 ℃ under fire, and then glazing, 900 ~ 1000 ℃ high temperature firing.
This need ink heat-resisting temperature is less than the former, in 900 ~ 1000 ℃.
In using the traditional high temperature ceramic and glass ink temperature than the above temperature over 600 ℃, 1000 ℃ or above.
Automatic glass cutting machine in some printing glass containers, sometimes more ceramic printing ink with low heat temperature, such as 180 ~ 200 ℃, the ink is also called low temperature glass ink, and organic pigment instead of generic or organic inorganic pigment coating material made of gold and gold glass cutting machine, bake for 10 minutes, at 200 ℃.
In the existing high temperature ink, heating temperature of 1800 ℃ ~ 2000 ℃ less ink, if need to baking at the temperature for a long time, less to meet the demand of the ink.
At present, the temperature about 200 ℃ baking capacity does not change color ink domestic few, mainly rely on imports, but foreign manufacturers who is relatively small, and the production of heat-resistant ink is not very stable.
Such as wheel label printing, printing in 200 ℃ baking to 3 h, often change color temperature, the application to meet the requirements of ink its cost is high.
At present, some screen printing industry developed countries have formulated inks.
