Thickness 2mm, let the natural leveling can be (Note: The above process is controlled within 30 minutes, so as not to increase the liquid viscosity, resulting in
6, the substrate 3-5 minutes after instillation Shuijingjiao observe glue surface without bubbles or dust particles, if any small bubbles, usable pin to pierce, found dead
have not stream Shuijingjiao to place, with pin lead
Crossing can be.
7, pouring good signs, at room temperature 20 ℃ -30 ℃ cured 10-24 hours harden, becoming left the surface of the crystal plate.
8, in case of stickers, trademarks, etc., in itself is very thin, and the boundary is not obvious, when pouring, likely to cause Shuijingjiao spill to reach 2mm thickness
will be difficult, so make Shuijingjiao grasp different situations
, Good control of viscosity in the application process can be placed 1-2 hours to increase the viscosity, adapt thin Shuijingjiao pouring.
9, making more than 2mm thick crystal glue signs, can be divided into secondary Epoxy, after the first dispensing, curing for 3-5 hours, then dropping layer.
10, Epoxy after cleaning, regardless of manual dispensing, or automated dispensing, after the completion of the machinery, equipment, containers are required to clean,
because the Shuijingjiao hardened, insoluble in any solvent, and therefore must be
It does not harden before the machine, the containers are required to clean (Recommendation: Use acetone or ethanol)
Epoxy signs of Procedure
Previously we mentioned before, due to the many types of signs, sign making procedure is not the same. Today, we explain in detail the main steps Dijiao signs:
1, first weighing apparatus, the job was a carrier, the gel appliances, drying equipment and other necessary equipment and utensils as well as dispensing operation to be
(such as nameplates, badges) ready in place.
2, the balance scale (or electronic scale), the job was carrier, ovens, countertops placed well, and adjust the level.
3, with a dry, clean, flat, wide-mouth container (a) A plastic weighing good, but in proportion to that good B plastic (typically 3: 1 weight ratio).
4, a glass rod with a round (or round sticks) AB mixture will be left, right or shun, counterclockwise while stirring container (with) the best tilt angle of 45 ° and kept
turning, stirring is continued for about 1-2 minutes namely can.
5, mixing good AB glue mixed with the bill charged soft plastic bottle were dispensing.
6, when the number of dispensing an area slightly larger or more drops of glue to accelerate the elimination of air bubbles in the glue, can be used to liquefied petroleum
gas as fuel to the fire * Laicui fire anti-foaming, anti-foaming fire when the flames * To adjust to the complete combustion shape
State, and the flame away from the work surface is best to keep a distance of about 25cm, fire * walking speed can not be too fast or too slow, you can maintain the proper
7, after the bubble completely eliminated until the job can be moved in a horizontal manner was heat curing oven, the temperature should be adjusted to about 40 ℃ bake 30
minutes and then increased to 60 ℃ --70 ℃, until the glue is completely cured
. (Detailed glue curing conditions please contact us)
8, if the effect of dispensing demanding, it is recommended as far as possible the natural levels drop too glue job was to be dry.
