Use temperature pyrograph the note!
Temperature pyrograph below 28 - refers to the temperature
31 ℃ below, can present the color temperature, when the temperature is higher than above 28 ℃, temperature change color is transparent color, present a second colour pyrograph.
According to the market trend of temperature change pyrograph gradually rise, so we need to know the detailed temperature pyrograph and use the matters needing attention.
A temperature, a pyrograph product strategy 1, change color and color can choose any color collocation (on the second floor
Color printing four-color screen printing or color)
, according to the rise and fall of temperature change color again and again.
2, warm color contains microcapsule color particles, with the characteristics of heat resistance, resistance to oxidation.
3, using human knowledge temperature to produce the product of change, also can be used for anti-counterfeiting mark.
2, use note 1, processing temperature control at 160 ℃, as far as possible reduce as far as possible when processing turn hot temperature heating time, (
High temperature and long time heating will damage the performance of the temperature)
2, heat transfer conditions: temperature: 130 -
150 ℃, time: 8 -
12 s, pressure: 0.
3 mpa3, thermal discoloration pigment of poor light fastness, will soon fade failure under strong sunlight exposure, so its only suitable for indoor use.
Should avoid strong sunlight and ultraviolet light irradiation, so beneficial to prolong the service life of color pigments.
4, color pigment in the hair color status and decolorization condition is different, the thermal stability of the stability of the former is higher than the latter.
And when the temperature higher than 80 ℃, the color system will start to degrade organic matter.
So color paint should avoid long-term stored under temperature higher than 75 ℃.
5, this product is stored in unopened packaging in good condition and normal circumstances, valid for 12 months, more than the period of validity after inspection qualified can continue to use.
In the use of temperature change pyrograph pay attention to these problems, can make temperature pyrograph to save more, hot stamping effect is better.
