1. Product introduction
Squeegee is a strip used in the screen printing process and
generally becomes a squeegee. Most of them are made of PU
materials. Depending on the characteristics of the screen printing
substrate, the accuracy of the printed pattern, and the printing
method, it is possible to select the squeegee of different hardness
and cross-sectional shape. The hardness of the squeegee is specific
to the hardness of its surface. Often expressed in Shore hardness
tables; 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees,
80 degrees, 85 degrees, 90 degrees. The cross-sectional shape
generally has a flat surface, a pointed surface, and a sloped
surface.
Product Size:
Taking 50*9 flat 75 degrees as an example, 50 represents the width
of the colloid, 9 represents the thickness of the colloid, flat
mouth refers to the shape of the knife edge, 75 degree refers to
the hardness of the rubber, and the length of the scraper of the
wooden handle is mostly one meter long. How long does it take to
use it?
2. Selection of hardness and cross-sectional shape of the scraping
rubber
Hardness selection
45°---65° (soft squeegee, suitable for printing uneven surface
products)
65°---80° (comprehensive performance, suitable for all kinds of
printed matter)
75°---95° (wear resistance, good solvent resistance, suitable for
printing fine patterns)
Section shape selection
Flat mouth scraping glue: common shape, with a certain
adaptability, can withstand the highest pressure.
Sharp squeegee: It has good flexibility, compliance, and reduced
pressure. It is suitable for printing on irregular surfaces and
irregular shape substrates.
Obtuse angle squeegee: It has the characteristics of flat and sharp
scraping, and it is not easy to appear collapse.
3. How to use
When using, try to avoid excessive pressure on the stencil. This
will cause the ink layer to be extremely thick, difficult to
control, and excessively wear the stencil. Therefore, the correct
way is to make the ends of the squeegee and the edge of the screen
suitable. The distance is then printed with the appropriate
pressure. Do not apply pressure when the squeegee is placed in the
handle or use too thick a size to force it in. The squeegee should
be allowed to rest regularly instead of continuously.
4. Cleaning
Wipe off excess ink with a cloth and then wash it with a soft cloth
dampened with a suitable solvent. Do not use strong solvents,
especially ink thinners, to clean the squeegee. The gel should be
left idle after grinding or before use to completely evaporate the
solution.
5. Grinding
It can be ground in a general and general way: belt type, roller
type, knife cutting type can only grind dry squeegee, and it can't
be wiped with solvent immediately after grinding.
6. Storage
For long-term storage, the squeegee should be wrapped and placed in
a dry and cool room to avoid direct light exposure. Otherwise, the
performance and hardness of the squeegee will change.
