Bottom before priming coating and pressure sensitive adhesive coating processing, advance coated on the surface of the substrate coating paint a thin layer at the end of the operation process. Corona treatment coronatreatment by corona discharge to the surface treatment of base material, to improve the surface properties of base material. Coating and coating to pressure-sensitive adhesive evenly on the surface of the base material, process. Blade coating knifecoating using scraper wipe effect, in order to achieve the pressure sensitive adhesive evenly on the surface of the base material, coating process. Transfer coating transfercoating adhesive tape base material and advance the viscosity of coated with pressure-sensitive adhesive composite substrate or the surface of the roller, and then separate, so that the pressure sensitive adhesive from the viscous base material or the surface of the roller transfer to the adhesive tape in the substrate. Gravure coating gravurecoating checkered coating using circular roller surface evenly or rule configuration of concave pits, the viscosity of the liquid adhesive evenly transferred to the shape of the substrate coating method. Extrusion coating extrusioncoating pressure-sensitive adhesive by using pressure liquid of extrusion, and apply the glue on the base material. Calendering coated calendercoating squeezing pressure sensitive adhesive mixture by rolling process in the process of base material on the surface. Hot melt coating hot melt coating will heating molten solid daub is on the base material of pressure sensitive adhesive coating method. Spraying spraycoating adopts spray method, the liquid spray to the base material of pressure sensitive adhesive coating method. Dry drying will base on pressure sensitive adhesive for removing the organic solvent or water in the process. Humidifying moisturizing to increase wet adhesive tape base material, the adhering materials or sub moisture content in the process. Put a roll of unwinding roll solution volume will base material in the operation. Winding winding will pressure sensitive adhesive tape winding on the roll core operations. Surface coiling surfacewinding produced in the process of using roller rotation surface friction as a pull, pressure sensitive adhesive tape winding on core winding operation. Center for coiling centerwinding using core winding in the process of active rotation of pull, pressure sensitive adhesive tape winding on core winding operation. The cutting and cutting the adhesive tape volume or semi-finished products, cut into small size small volume process. Cutting plate cutting and slicing slice roll tape semi-finished products by slice method points cut into the required width of the finished product volume cutting way. 22396 / T - GB - Article 2008 a type cutting and slitting roll adhesive tape and cut into strips, then each strip tape volume respectively on different core winding way of cutting. Cutting sheetcutting cut pressure-sensitive adhesive products semi-finished products into the massive finished cutting way. Die-cutting diecutting cut sheet pressure sensitive adhesive products into the required design and shape of finished cutting way. Crosslinking cross - Linking, curing in sensitive adhesive components of the process of forming chemical bond between molecules. Thermal crosslinking heatcross - Linking under the effect of heat, the realization of crosslinking. Radiation crosslinking radiationcross - Linking, radiationcuring radiation curing radiation energy are used to achieve crosslinking process. Composite lamination to a substrate or pressure sensitive adhesive products with another kind of pressure-sensitive adhesive products in the process of pressure together. Aging treatment maturing well into place the pressure-sensitive adhesive products under certain conditions for a period of time, make its performance to achieve stable process. Heattreatment thermal aging heat treatment processing will pressure-sensitive adhesive products placed in a certain temperature conditions for a period of time, make its performance to achieve stable process. Anti-sticking processing releasecoating coating process of anti-sticking agent on the underside of the base material. Film filmcastingandlamination on paper, cloth, such as base material high delay the operation of coating a layer of polymer membrane.
