Glass screen printing screen printing screen printing machine

     Glass screen printing, is to use silk screen printing, the use of glass glaze, decorative printing on the glass.Glass glaze is also called glass printing ink, glass printing material, it is by the coloring material, links mixture and stir paste printing material.Coloring material by inorganic pigments, low melting flux (lead glass powder);Link is commonly known as for suet in glass screen printing industry.After printing glass products, to put in the furnace, in the temperature of 520 ~ 600 ℃ fire, printed on the surface of glass glaze on the glass to consolidation, form the colorful decorative pattern.If the screen printing and other processing methods and use of words, will give a more ideal result.For example, using methods such as polishing, engraving, corrosion in printing before or after processing was carried out on the glass surface, able to improve the effect of printing double.
      1.Glass etching silk screen for a long time, etching of the glass decoration, is a hot wax layer on the glass surface and other solid materials, as a corrosion resistant layer, then use a needle on the coating, such as a knife engraved designs, glass surface, and then on this site with hydrogen fluoride acid corrosion.This process continues today and application of factory, but its processing method is time-consuming, laborious and inefficient.Screen printing etching process, made the etching of the glass decoration is simple, time and energy.Etching of the glass screen printing, hot stamping and cold two methods.Thermoplastic etching screen printing, paraffin wax, bitumen, stearic acid, preparation of the adhesive, add a small amount of corrosion resistant powder made from corrosion resistant material, by hot stamping silk screen version, according to the pattern of design, the printing material scrapping printing to the surface of glass, forming resistance to corrosion of the membrane.Glass on corrosion resistant film shows parts that are need etching pattern.Etching with fluorine acid chloride, with boiled water wash away after etching is printed on the glass of the corrosion layer.Etching the glass screen printing, also can use cold printing method.Resist printing material can use special bituminous paint and corrosion resistant powder, also can buy commercially available in accordance with the ink.After the completion of the printing, to resist film completely dry, can proceed to the hydrofluoric acid corrosion.Hot stamping is suitable for continuous, sifang continuous two designs of etching, etching patterns of the cold seal adapt to separate.

        2.Glass ice-patterned silk screen Ice grain commonly known as the orange peel, it is actually very small low melting point glass particles.This small glass particles, lead composition is high, with colored and colorless, the hue color has red, yellow, blue, green, white, etc., can also formulate the middle tone.Screen printing ice flower decoration, simple but elegant and easy, more used for building decoration and the arts and crafts glass decoration, decoration such as senior glassware, lamps and lanterns.Screen printing glass ice flower decoration, is the first screen printing colored or colorless glass flux of glass surface layer (flux), then the ice glass particles on the glass fluxing agent layer.Through 500 ~ 590 ℃ sintering, flux and ice particle layer on the surface of the glass embossed effect of the eutectic.Such as on the glass screen printing is colored flux, and micro appearance is transparent, through high temperature eutectic, the glass ice patterns flux layer of the fading, and formed on the surface of the glass colored, uplift of transparent embossed pattern.
       3.Glass frosting silk-screen frosting is on the glass products, adhere to a certain size of glass glaze powder, after the high temperature of 580 ~ 600 ℃ baking, melt glass glaze coating on the glass surface, and displays with the main body of a different color glass decoration method.Adhesive glass glaze powder, white washing brush besmear brushs are available, and can also use rubber roller roller coating.Through the silk screen processing, can get the frosting surface floor empty pattern.The method is: on the surface of glass products, silk screen layer formed by resistance flux designs.To be printed on the designs of dried, then using the frosting process.Then after high temperature baking, no designs of frosting surface melting on the glass surface, and logo printing place due to the effect of flux, on the design of the sand surface can't melt in the glass surface.After baking transparent floor empty pattern appeared through the translucent sand surface, the formation of a special kind of adornment effect.Frosting printing flux, composed of ferric oxide, talc powder, clay and so on, with ball mill grinding, fineness of 350 mesh, screen printing before use glue blending.

     4. The glass screen printing ion exchange shading Through the silver with the sodium ion exchange in the glass, and then make its reduction, into a metal colloid, colored glass can be obtained.In a transparent glass with silk screen printing ink containing the silver ions only to print the part for coloring, burnt after wash, only part of the printing is yellow brown.Firing conditions, different colors and the concentration change will occur.Because there is no colored sections and coloring reflection is poor, so there is no completely natural feeling, like glass melting coloring.Words and mark on the glass coloring and car rear window of the heat treatment, and experiment with the amount of scale of Jane brown, is made in this way.This decoration process of printing ink (printed) by silver, copper sulfate, carbonate (burning powder), two iron oxide, talc powder, etc, with a small amount of zinc powder as catalyst.
      5.Silk screen touch control panel In the design of microwave oven temperature program, use the switch combined with a microcomputer.This switch is different from the usual mechanical switch, is printed on the glass plate switch, no moving parts, no convex concave, very smooth, easy decontamination, touch switch.The control panel has the conductivity of the membrane surface cover, in the surrounding screen printing ceramic ink for decoration and display text.Its advantage is resistance to mechanical abrasion, chemical corrosion resistance, easy decontamination.In addition, the design to make the colored glass, and can be printed on the back of the organic coating, because the back can not directly contact, strong durability, ink choice is bigger also.
       6.Extinction silk screen on the surface of the glass The glass surface extinction oil ink (Belgium), with the silk screen plate on the soda-lime glass, washing, in a few minutes later the effect just like dark brown glass.Is usually using fluorine acid etching of the glass, there is a certain risk, with the ink does not contain acid, operation is simple, its extinction effect has the same effect with etching.

      7. The electric mist device screen printing In order to prevent car rear window condensation water vapor, printing more and more of the electric mist mechanism.This kind of screen printing method is silver paste on the smooth glass paint line, and during the bending process was carried out on the glass to fire at the same time.Rear window fogging, vague line heating by electric current, raise the temperature of glass surface, remove the water vapor.The electric mist device electrify, some cars not use manual switch, but the electricity, the power automatically.The automatic device of sensor is serrated electrode with silk screen printing on a sheet of glass, and on its cover a layer of moisture, using the humidity change than automatic control of electricity, power cuts.
      8. Screen printing LCD digital display device, liquid crystal display element is the interval of 10 mu n.Around the two pieces of thin glass of sealed, injecting liquid crystal, block made of sprue.On the two pieces of glass surface, screen printing is "8" glyph of transparent electric conduction, the "eight" word consists of seven parts, can increase voltage, partly to show the number of (0 ~ 5).Making this "8" font design process, the first is in field on the glass with the electric conduction, spare acid ink to silk screen printing on only the "8" glyph part, then use acid etching, removal has not been printed part of the transmission.Silk screen printing in the electronic product manufacturing In the process of electronic products, screen printing has become an indispensable process.Such as product housing decoration, printed circuit, thick film IC, solar batteries, electricity;Falling, capacitance, piezoelectric element, photosensitive element, temperature sensor, liquid crystal display element, and so on, in the process of production have different levels of the silk screen printing process.
