Aluminum foil can also be printed with water-based ink. As a non-absorbent substrate, aluminum foil poses a major challenge to water-based ink printing. However, some aluminum foil products that require food-grade printing cannot be printed with oil-based inks, so water-based inks have become the best choice. However, due to the poor absorption of aluminum foil to water-based ink, many inexperienc...
First, water-based lotion Aqueous emulsion is a colloidal dispersion system with water as the continuous phase and oil or other non-aqueous substances as the dispersing phase. It is a stable dispersion system formed by tiny oil droplets coated with surfactants. Water-based emulsion has many significant advantages, such as its low viscosity, easy to brush, easy to clean, non-toxic and harmless. The...
There are several main reasons for water-based emulsion breaking: 1.Large temperature changes, water-based emulsion is easy to separate into water phase and oil phase at high temperature, and easy to crystallize at low temperature. 2.The selection of emulsifier is improper, and the type and dosage of emulsifier are different, which has a great impact on the stability of emulsification. The choice ...
Before the textile coating, it is necessary to pretreat the textile surface to ensure the adhesion and quality of the coating. Common surface treatment methods are: cleaning, degreasing, polishing and so on. Cleaning can be done with hot water or solvents, degreasing can be done with alkaline or acid degreasing agents, and polishing is done by mechanical removal of surface hair. The choice of coat...
The grinding fineness of paint is one of the important qualities of color paint, which has a great impact on film forming quality, film gloss, durability, storage stability of paint, etc., and is one of the routine testing items of paint production. The fineness of the paint refers to the size of the particle size or the uniformity of the dispersion of the pigment or the bulk pigment, and the unqu...
The main reason for water-based ink drying 1.Water-based ink: water-based carton ink, non-woven ink, paper towels, paper cups and paper bags and other packaging printing; 2.Water-based polishing oil series: water-based polishing oil, polishing oil, high gloss, wear-resistant, matte, waterproof, antifreeze and other environmental protection water-based products. Water-based ink drying is mainly cau...
First, resin reaction temperature standard The reaction temperature of resin is an important process parameter, which has great influence on the reaction rate, physical properties and chemical stability of resin. In general, the resin reaction temperature should be determined according to different resin types and catalyst types. The following are some commonly used resin reaction temperature stan...
Flexo is a flexible, high resolution, warped letterpress plate. In recent years, flexo printing has developed rapidly in the field of printing, and its development prospects are generally optimistic. Flexographic printing presses transfer the right amount of ink to the substrate through a unique mesh roller. The appropriate use of ink is directly related to the printing production operation and pr...
Architectural coatings mainly use water as a dispersing medium and diluent, and its advantages are that the water of the dispersing medium is non-toxic and harmless, manufacturing and storage and transportation without the danger of explosion, no pollution to the environment, and to solve the problem of excessive VOC(volatile organic compounds) of solvent-based coatings at normal temperature. Film...
I.Definition The emulsion is a colloidal system with a particle size of 0.1~10μm formed by two insoluble liquids through the action of emulsifier. Secondary dispersion refers to a colloidal system formed by particles (or molecular groups) less than 1μm are dispersed into a continuous phase (such as water) under the action of a stabilizer. By definition, the formation of emulsions and secondary dis...
1.Type: There are three main types of water-based acrylic resins, including emulsion, water dispersion and aqueous solution. The emulsion is synthesized by emulsifying olefins in water under the action of water-based free radical initiator. The aqueous dispersion is synthesized by free radical solution polymerization or stepwise solution polymerization. Aqueous acrylics are directly soluble in wat...
Water-based resins can be divided into water-emulsion, water-dispersed and water-soluble according to their appearance. There are many people think that this is the same resin, in fact, it is not only the appearance is not the same and the use and characteristics are very different. Water-based acrylic resins are generally divided into water-based emulsion acrylic resins and water-soluble acrylic ...
Compared with solvent-based acrylic paint, the paint made of water-based acrylic resin has the advantages of stability, safe use, environmental protection, reducing environmental pollution and saving resources! At present, it has become an important development direction of the coating industry. The coating using water-based acrylic resin is a low-pollution or even pollution-free environmental pro...
Water-based coatings, acrylic resins are commonly used resins that can not be avoided, commonly used metal coatings, ABS, PC coatings, glass coatings that require hardness, most of them will be applied to acrylic resins, especially solid acrylic resins. There are many varieties of solid acrylic resins, and some solid acrylic resins can be used to produce water-based paints, including the popular l...
water base varnish for glass Does not contain benzene, esters and other harmful solvents, does not contain free TDI, does not burn, is the latest environmental protection glass process paint, by the international and other authoritative verification institutions assessed as the real green environmental protection products. Solve problems It is required to blister at 75℃ for 30 minutes and it is re...
Polyurethane coating film bright and full, hard wear-resistant, oil, acid, chemical and industrial waste gas resistance, good electrical properties, and a variety of resin miscible, can be adjusted in a wide range of formulations to meet different needs. Widely used in wood, automobile, aircraft, machinery, electrical appliances, instruments, plastics, leather, paper, fabric, petrochemical an...
