As seen from the above table, add viscosity modifier in sodium alginate base slurry, the viscosity degradation ratio is rule comparatively, and PH guarantees thixotropic property good in slurry and reach in reasonable interval, reaches to control viscosity and reduce being stained with property, makes slurry sticking and smooth and be not stained with.Because the constant lubricant viscosity that added of the amount of sodium alginate in slurry has reduced, illustrate that this slurry is adding shearing stress disposed slurry viscosity along with stress and shearing rate increase and reduce, after shearing stress is eliminated, viscosity is replied as before, be a good reactive printing slurry, the stamp speed of a motor vehicle increase shearing rate of doctor increases, and size performance is stable, be not stained with the edge of a knife, do not drag slurry, receive slurry clean, stabilised efficiency improves.
In large PLATE SCREAM PRINTING or will enhance productivity in conventional stamp, the speed of a motor vehicle when improving stamp is a key, guarantees printing effect and will improve the speed of a motor vehicle, and a kind of viscosity appropriateness be arranged, the mill base that rheological and thixotropy well and not are stained with, improve production efficiency and product quality.
Use that concentrator of the present invention is starched by the sodium alginate base and viscosity modifier is mixed by a certain percentage, the ratio of adjusting sodium alginate base slurry and viscosity modifier according to the depth of printed color obtains the suitable concentrator of viscosity.
Concentrator suitable viscosity of the present invention, glue and be not stained with, thixotropic property is high, the mill base that modulates with this concentrator, carry and dye material on fabric the time, be not stained with stamp instrument and fabric, effective must avoid that traditional concentrator easily occurs in printing technology to drag slurry to scrape unclean because being stained with the edge of a knife, because being stained with net and traction.When traditional printing paste can adhesive tape prints to mill base on cloth cover and pulls up stamp not bright and clean, the color lump of lines produce moire and inhomogeneous, the moire effect incomplete, withered pen displacement, heterochromaticly stain according to legend or be infected with the bad defective such as Bai Di and produce, having produced bad defective must stop and look into, parking eliminating etc. affects the work of efficient and loses time, after the mill base of concentrator modulation of the present invention improves the speed of a motor vehicle, printing effect still can be guaranteed, the speed of a motor vehicle can improve 30% to 50%, production efficiency can improve 100%, and remarkable benefit improves.
Concentrator acid and alkali-resistance of the present invention and ionogen performance are good, have the stronger carrying capacity that gets, and dyestuff is anchored on fiber by various effects.Dye yield is high, saves dyestuff.This concentrator is sticking and smooth but be not stained with, dispersing property is good, can make and dye the material Uniform Dispersion and accurately be fixed on the certain position of fabric and not imbibition, easily producing stream when having avoided using traditional concentrator oozes, the not bright and clean or breakthrough of hachure, large color lump Dry Sack is uneven, and the disadvantages such as color dot make the decorative pattern clear-cut.Mill base with concentrator modulation of the present invention, make composition complexity, the abundant picture proof of element just can ideally print to existing printing equipment and become possibility on cloth, be unlikely to excessively to delete element or the color of original picture proof, the more design inspiration of Designers and freedom of creation can access performance.
