Introduction Of Electrostatic Flocking Electrostatic flocking is widely used and popular in industrially developed countries, such as the United States, Italy, Germany and Japan, because of its unique decorative effect of suede and embroidery, as well as its simple process, low cost and strong adaptability.In recent years, a variety of electrostatic flocking products have also been developed in China.Electrostatic flocking has a wide range of applications, such as the use of flocking machine can process different fabrics, different grades of textile fabrics. Colored velvet paper made of various kinds of fluff can be used for art decoration, display boards, window, trademarks, etc. The craft painting style of various design pictures has a unique style. Machining Method Flocking processing can be divided into descending method, ascending method, transverse flying method and upward and downward flying method according to the different direction of flying villus. More than 80% of domestic flocking processing equipment adopts the descending method, so the descending method is taken as an example to explain its working principle.The upper plate is a plate type metal mesh frame, and the lower plate is a metal plate bracket, which is covered with a screen printed with adhesive to be flocking base cloth. The upper and lower two plates are respectively connected with wires to the positive and negative output ends of the high voltage electrostatic generator. The fluff in the hopper falls on the negative pole of the metal mesh due to the rotation of the fuzzy-supplying shaft. The villi are charged by contact with the negative electrode during the descent, causing them to partially align in the direction of the electric field.The upper plate is a plate type metal mesh frame, and the lower plate is a metal plate bracket, which is covered with a screen printed with adhesive to be flocking base cloth.

The fluff in the hopper falls on the negative pole of the metal mesh due to the rotation of the fuzzy-supplying shaft. The villi are charged by contact with the negative electrode during the descent, causing them to partially align in the direction of the electric field.When the villi contact the negative electrode, conductive current will be generated in the fiber because the conductivity of the electrode is higher than that of the villi, and the villi will generate negative static charge, which makes the villi have a great degree of elongation and flight in the electric field. The villi will fall vertically to the base cloth with adhesive pattern on the net at a high speed, forming fine suetex-text. In electrostatic flocking processing, the villi are not only charged due to contact, but also charged due to polarization effect when entering the electric field, which ensures that the villi move toward the p...

The use of flocking glue is different from that of ordinary glue. General flocking process can be divided into three kinds: 1. Flocking box, according to the need of flocking products make it the size of the corresponding flocking box, then placed in the flocking box of villi, connected to the power supply, make the flocking box to form a strong magnetic field, when the product from the side wear of flocking box to flocking box, the other side of the villi can be directly adsorbed on the coated with flocking glue products, and then directly to dry or drying. 2. Flocking nozzle type: This method is very simple. It generates voltage through the power supply of flocking machine, and then puts the fluff into the nozzle. In this way, the fluff in the nozzle will also generate a large amount of negative charge. 3. Flocking machine assembly line, this way to use professional flocking machinery, can make the goods a one-time completion of gluing, flocking, drying and other processes.

The peeling protective coating is a liquid protective coating made of waterborne polyurethane, which can be sprayed on the surface of automobiles, furniture, electrical appliances and other objects as a protective coating.It has good formativity, can in complex shape surface to form a layer of continuous, uniform stick, strength, transparent protective coating, no need baking, room temperature drying quickly, without harmful gas such as formaldehyde, benzene, ammonia release, after dry film, easy from the object of the zhang jie, no temperature requirements, without water and solvent cleaning, stripping of film can be recycling use, the coating resistant to sunlight exposure, Resistant to water, oil, alkali, salt liquid, dilute acid function, coating temperature dependence is small.Production and construction technology is simple, applicability is wide without environmental pollution of environmental protection paint. Peeling coating has strong water resistance, oil resistance, corrosion resistance and insulation, spraying on the surface of the object, that is, the formation of a layer of peeling film, through the film of the object's effective isolation, to prevent dirt, rust, acid and alkali, abrasion and a tear that is the new state of mind. Appearance: 1.White or blue liquid 2.Film appearance: smooth, no cracks, no bubbles, no wrinkles, can be peeled without adhesion phenomenon. Component: aliphatic aqueous polyurethane dispersion. Technical parameters: Color: Blue or white Viscosity: can be adjusted according to customer's actual operation needs Drying time (room temperature) : table dry 20min dry 2h dry (60℃) 7min Flexibility: good temperature resistance: 160℃ for 24 hours Acid resistance: 25%H2SO4 24 hours alkali resistance: 40%NaOH 24 hours Salt resistance: 30%NaCl for 24 hours
