Ordinary polyester mesh: woven from ordinary polyester fibers.Advantages:
A.High tensile strength, able to withstand high tension
B.Good wear resistance, can withstand printing ink pigments and squeegee on the screen wear.C.High light resistance, in natural room temperature light.Long storage period D.Not sensitive to climatic factors, small moisture absorption, strong heat resistance E.Low elongation, good dimensional stability
F.Chemical resistance is strong, can withstand general acid, but resistance to general alkali limited common polyester screen shortcomings:
With the combination of photosensitive milk, overink, wear resistance is not as good as nylon.Plate before the screen plate needs to be processed before the screen (that is, the screen needs to be coarse degreasing and grinding)
3, high tension low extension polyester screen: from high tension polyester fiber woven.In addition to the advantages of ordinary polyester screen, and its outstanding advantages are:
A.Its structure is more stable, the tension stability is high after stretching the net, the accuracy stability is better in the long-term printing operation.
B.Can withstand high tension, and low extension, improve overprint accuracy C.When printing, mesh spacing is small, mesh and ink stripping very well D.Long service life, strong mechanical and chemical resistance
4, single flat screen: woven from polyester fiber.It is the polyester net through a pad press stick and a rubber stick to press, forming a screen of the side of the press flat.So this kind of screen thickness reduced by 25%, the opening area is also slightly reduced, in other processes at the same time, the thickness of the printing ink layer is reduced, more conducive to the curing of UV ink.It is suitable for UV UV ink, so also known as UV screen.Its outstanding advantage is: a. can save UV ink 35%
B. press plane in printing ink, printing, scraping board on the flat screen move is smooth, mesh long service life.
C. High definition printing, good dimensional stability, able to print high-quality products.5, stainless steel wire mesh: woven from stainless steel wire, with the following characteristics: A.High tension and low elongation, excellent screen stability B.High tensile strength, good inking
C.The line diameter is fine, the aperture is large and the line diameter opening is quite uniform, the printing precision is high D.Resistance to chemical resistance, wear resistance, moisture resistance are good
