How is the paint printed color paste made? The mixing method of the color slurry.

original title: How is the paint printed color paste made? The mixing method of color slurrythe composition of paint-printed color pulp, the effect of its printing color will also be different. In order to control the quality of the printing process, it is necessary to mix the colors of the color paste to meet the specific appearance of color requirements. This article for you to bring paint printed color slurry blending methods, interested users may wish to take a look at it!the composition and function of coating printed color slurry:the type of paint printed color paste used in production is simple, usually only coatings, adhesives and thickeners, special requirements can be added to other additives.coating is a slurry made from pigments, moisturizers, diffusers, stabilizers and water, which are mixed and ground in proportion. Paint gives the color of the printed fabric, determines the color vividness of the product, affecting the color of the sun fastness, climate fastness and sublimation degree. The basic requirements of printing on the coating are:1, higher coloring force and cover force. Coloring force is to give the amount of color, a certain amount of paint can be printed color thick degree, is one of the main technical indicators of paint. The masking force refers to the ability of the coating to completely cover the printed fabric, often expressed by the amount of pigment required for the covered area. The size of the coating's cover force, influenced by the amount of pigment, particle size and other factors, is another important technical index of coating.2, high light resistance, heat resistance, climate resistance.3, good chemical stability, acid, alkali, oxidants, reducing agents, dry cleaning agent has a certain stability.4, appropriate density and dispersion, to ensure that pigment particles in the dispersion system neither floating nor precipitation.5, good sublimation and smoke fade.adhesives are molded polymer compounds, also known as adhesives, with an average relative molecular mass of about 100,000, of which synthetic polymers are the most commonly used. Common commodity adhesives are emulsions that are dispersed in water in a fine state, with a solid content of 30%-40%. The effect of the adhesive is to form a transparent film with strong adhesion after molding, which binds the coating to the fabric. The adhesive therefore affects the feel of hardened products, as well as soap washing, brushing, dry friction, wet friction and other color fastness.thickeners act as carriers in coating printing, dispersing paint adhesives and other additives evenly and transferring them to the knitwear. The thickeners used are emulsified paste and synthetic thickeners. The main problem in the use of synthetic thickener is not resistant to electrolytes, electrolytes will make the printed color slurry thin, viscosity decreased, printed pattern seepage, affecting the printing effect. Synthetic thickeners can be used in full coating printing production. Anti-printing and dyeing coating printed color slurry contains electrolytes, should be noted.Howpaint printed color slurry is formulated?because of the different composition of paint printing color slurry, the configuration of the paint printing color effect is also very different, in order to control the paint printed color slurry quality, it is necessary to strictly control the color slurry mixing process. At present, the color slurry blending can be manually operated, but also can be done through the automatic slurry mixing system. Automatic color slurry mixing system is the use of computers, color matching software and color measurement system. Through the application of automatic color slurry mixing system, printing color chrome digitization, precision and reliability, high production efficiency, is for the development direction of coating printing color paste mixing.color paste preparation method: 1, computer color matching in the computer color matching system, should first establish the printing process base database, that is, each dye according to different concentrations of small sample printing, and then use a chromometer to test the printing sample, and as the basic data stored in the computer to provide color formulation. Future samples as standard samples on the colormeter test, the measurement system according to the test results in accordance with the requirements in the database to find the best formula, according to this side of the printing proof, and then test the color difference between the sample and the standard sample, the color difference is not within the allowed range, then the measurement system to correct the adjustment, again proof color difference, until the color difference in the allowed range, at this time provided with a color-to-color prescription color scheme.2, automatic pulpingpulping system is a very important part of the entire automatic slurry mixing system, it can be used with the color scheme, can also be used alone. That is, the color slurry modulation can be done by measuring the color scheme or by entering the desired process formula through the keyboard. The system can be configured with dozens of high-level barrels. Before mixing, the original paste, dye solution and additive solution should be pumped into the corresponding high bucket, and into the compressed air, to maintain uniformity. After the color matching system provides a slurry prescription, the pulping computer can start working, the electronic scale automatically along the track from left to right, according to the prescription to add a certain amount of raw paste, dyes, additives and water, all the feeding data can be displayed on the display of the computer console, but also with the printer to print the slurry prescription, after the discharge is stirred by the agitator to get the color slurry.is the small collection and finishing of the "paint printed color paste how to make?"
