Screen printing squeegee hardness range and choice
A: 45 ° --65 ° (soft squeegee, suitable for uneven surface printing products)
B: 65 ° --- 80 ° (Comprehensive performance, and for a variety of print)
C: 75 ° --- 95 ° (wear resistance, good solvent resistance, suitable for printing fine pattern)
Screen printing squeegee purposes:
1, allows the ink to flow through the screen.
2, make contact with the screen printing material.
3, to ensure that the screen surface and the medium and adapt.
4, to remove excess ink on the screen.
Screen printing squeegee maintenance storage
1, when the stock squeegee should lie flat and not labeled volume placement.
2, should be placed after opening the entire volume of the cord so that the cord 24 hours to complete Shuzhan Ping before use.
3, storage should be relieved no squeegee handle up using the cord, the cord can not touch anything.
4, the storage temperature should squeegee at 200C-250C in a dry environment, away from the ink, because the squeegee can absorb moisture from the air and solvents.
5, squeegee or handle with ink can not stay overnight storage.
6, squeegee not a long soak in the solvent, although some can be resistant to many solvents squeegee, but a long soak squeegee will temporarily deform and lose elasticity.
7, spent squeegee rinse immediately to avoid ink drying squeegee early. Squeegee handle the cleaning and scraping should not have any ink residue
Traces, or imprint squeegee and then the next printing.
8, with a soft cloth to clean the squeegee, squeegee to follow the direction of cleaning, or reverse the damage to the printed edge cleaning squeegee.
Screen printing squeegee grinding:
Squeegee printing end due to frequent friction with stencil eventually damaged deformed. You can make use of scraping grinding machine squeegee edge becomes sharp again. We noteworthy that during squeegee grinding a few items:
1 Use finer grinding wheel so that the squeegee scraping grinding material at a minimum loss. Ensure squeegee edge clean, no stain point, does not melt, the rotational speed of the wheel to be lower.
2 When you need to quickly wear out a large piece of plastic scratch material into a coarse grinding wheel can grind scratch.
3 If only the squeegee ground smooth, use a very fine sandpaper on it.
4 When using the cutting knife to cut off part of the squeegee, need to re-polish the squeegee cleaning must ensure there is no gap after cutting.
5 After printing squeegee sprinkle immediately with abrasive scraping, scraping gum after printing to stand for 24 hours after the solvent has completely evaporated then scraping grinding.
6 In addition to the straight outer edge of the squeegee to ensure that freedom squeegee heights are consistent along the entire squeegee length.
How to choose Squeegee ?
In screen printing, scraping gum or name squeegee effect: to make printed materials through screen holes uniformly and quantitatively transferred on the substrate.
Factors affecting the printing effect: the angle of the blade and the screen version of the constitution, pressure, speed blade movement, edge shape, stretching quality of printed material (ink) and performance substrates and so on.
Using the blade angle and outflows related printed material, the smaller the angle, the more the amount of printed material outflow. Screen printing is a wide variety of substrates, printing requirements are different, in order to achieve the intended purpose it is necessary to correct selection screen scraper, and use a blade in turn influenced by the following factors:
1. Stretching silk screen quality required to achieve a certain tension, and the tension of the material by the mesh size is limited, the tension is usually nylon 8-10kg / cm square, polyester 8- 10kg / cm square, stainless steel 10- 13kg / cm squared for screen tension high hardness blade can be used for wire stretched looser version can only use low hardness blade, or affect the amount of printed material through.
2. Printed material (ink) performance of printed material pH determines the choice of blade (board); scraper seat from printed material corrosion. According to the viscosity of the printed material, fineness, hardness choose blade length, thickness, hardness; printed materials of high viscosity blade length corresponding to a long point, printed material hardness squeegee also need high hardness.
3. Performance printing substrates on a hard object and surface roughness of the substrate is poor. Use a softer blade. Otherwise use a hard scraper.
4. Printing requirements printed material is transferred to the amount of the substrates more, should be used in soft blade.
5. Printing pressure printing pressure, should not be used too soft blade, otherwise the contact with the substrate surface screen will be leaving too poor printing results. Most currently used blade type scraper rubber and polyurethane rubber scraper; rubber scraper blade is to use a more common and inexpensive. Proportional to its solvent resistance and hardness. Some users own acid-resistant rubber, processed into the blade there is poor wear resistance, insufficient straight edge and other shortcomings. Acid rubber plate hardness less than the hardness of the rubber scraper, adapted to the needs of the blade portion of the low hardness. Polyurethane has a high strength, high wear resistance, mineral oil and paraffin solvents, ozone resistance, low temperature and resistance to radiation and other properties; in the case of high hardness is still very high resilience.
Urethane rubber molding methods are casted, solid molding, thermoforming three. China-made blade is formed by casting. Polyurethane is divided by the molecular structure; distribution type and ether type two.
Ester poor solvent resistance than ether type water resistance. In screen printing, printing on different blade performance have certain requirements, such as resistance to printed material, acid and alkali resistance, oil resistance, abrasion resistance, there is a certain degree of hardness, strength, resilience, straight edge, a certain length, thickness, and other performance indicators. Each performance blade will be directly reflected in the stability and effectiveness of silk screen. To print outlets clear, pattern, require the entire blade edge on the nip pressure suffered equally. Elastic blade hardness makes impression thin line and a solid, uniform pressure points suffered, not only want to have a straight sharp edge, and hope blade having a certain flexibility, hardness. So that one can make the screen quickly rebound, to ensure the normal screen, on the other hand will also prevent the screen scraper rub hair, effect halftone printing durability.
Elastic blade requirements; must ensure that the blade of distortion force against change, so the amount of ink scraper pushed out too uniform.
Blade hardness; it must be able to guarantee a certain amount of ink pushed out; great hardness of the ink pushed out less, and vice versa more.
Indian big screen version of the picture, a little blade hardness may be appropriate, but will have to use a large squeegee hardness when printing fine patterns.
The ink viscosity, the actual length of the blade can be adjusted even more than the width of the pattern, and each side over graphics 2-10Cm, viscosity, blade should be longer. To ensure that the amount of blade pressure force uniform and stable ink. The proper selection of scraper will help improve the level and ideal screen printing results.
Screen printing requires experience in long-term practice. After we focused on the screen printing of "screen-printing technology and equipment," "photosensitive plate-making process," "color tone screen printing," "common faults produce plate and prevent quality problems cause" "appears and the screen printing approach "and other relevant knowledge.
