Although additional retarder can play a role, but the ink on the screen version of the drying rate is still a very difficult problem. Use background discharge method is an effective way to solve the problem of dark garment printing. However, this application can not be called an environmentally friendly way, because formaldehyde content is relatively high, and the pungent smell of background discharge its application is greatly hindered. Many printing manufacturers even prohibit the use of this method in the production process. However, in recent years, along with in-depth research and development of ink discharge, and related technology has made tremendous progress. It contains formaldehyde content has decreased odor also have a very significant improvement. In some of the new products introduced in the original discharge agent formaldehyde has been replaced by zinc sulfate sodium equivalent material, and its effectiveness is still quite outstanding emergency. While there has been some breakthroughs in technology, but look forward to discharge ink will have a more long-term development, to encourage the development of more environmentally friendly products PP ink wholesalers, and maintain this driving force can continue. Water-based ink technology in a few years has made tremendous progress. Thanks to a new type of wetting agents and emulsifiers, ink dried on the screen stencil various original fault has been significantly curbed. Existing some new ink on a screen stencil residence time longer than four to five times before, but did not clog or dry phenomenon. Even water-based ink due to evaporation in the dryer or heat generated by the impact of extreme weather and lose moisture, can be re-emulsification and re-use. Water-based ink characteristics and use 1) is used to deepen the color pigment, the amount should be controlled from 0 to 30%, more than 30% will cause the ink in the binder content is too low, resulting in decreased adhesion and abrasion resistance . 2) pH value of the stabilizing agent for adjusting and controlling the pH of the aqueous ink, to stabilize at 8.0 to 9.5, to ensure the water-based ink status. Meanwhile, it can adjust the viscosity of the aqueous ink, and the ink dilution. 3) slow drying agent used to reduce the degree of drying ink, slow drying agent can inhibit and slow down the water-based ink drying speed, to prevent ink drying ink wholesalers plating on the plate, reducing blocking version and paste version of such printing faults occur . The amount of slow drying agents should generally be controlled from 0 to 10% of the total amount of ink, if adding too much volume, ink drying is not complete, the print will stick dirty or odors. 4) Water-based ink is mainly used to reduce diluent color depth, the amount is not limited. But adding a lot of diluent may cause a slight increase in the viscosity of ink, this time can be adjusted at the same time add a little thinner. 5) The diluted profit is mainly used to reduce the viscosity of the ink, the amount should be controlled within 3%, so as not to reduce the color depth of the ink ink ink can keep the pH constant. Diluent should be added slowly with stirring to prevent the viscosity is too low. If you add more thinner or use high hardness water dilution will produce bubbles of ink wholesalers ABS, then should join defoamers. Problems arise mainly due to the foam 6) is its water-based ink using water as a diluent, in the emulsion polymerization must use a certain amount of emulsifier, the surface tension of the emulsion system greatly decreased.
