(Summary description)Plasma surface treatment can improve the surface adhesion of various materials, so that all kinds of materials in printing, spraying, bonding, welding and other processes, glue, ink, solder joints, coating, etc., effectively adhere to the surface of the material, to ensure the firmness. About printing, pad printing, screen printing, printing, thermal transfer, lettering, printing process, such as in the process, plasma surface treatment has obvious effect, before printing, first for plasma surface treatment, in order to improve the material surface adhesion and hydrophilic, make the printing after printing satisfy clients' demand for all kinds of inspection, the inspection requirements, either with a specific type of 3 m tape, have a plenty of judged by printing fastness printing whether accord with the requirement of the customer, have a plenty of friction with his nails to test; Some use a hundred squares to detect; Some use special cotton fabrics for friction testing; No matter which test method is used, the purpose is to test the firmness of printing and whether it meets the customer's requirements. Spraying aspects, involving stainless steel spraying, plastic spraying, etc., these processes are generally used in stainless steel thermos cup, auto parts, the need for pre-treatment of products, the particularity of product use reflected in the product use environment and frequency. If some parts on the car, PP + GF is generally selected materials, the characteristics of the material surface adhesion stress is low, heat resistant, wear resistant, good toughness, but the material itself but the corrosion resistance is not high, so in the subsequent process need to spray coating corrosion resistant layer on the surface of a material, because of material itself bond low, surface treatment by plasma surface treatment machine, spray on subsequent strong degree, can effectively guarantee; Such as stainless steel insulation cup, before spraying, the need for multiple pickling process, to ensure that the surface of stainless steel pollutants are effectively cleaned, the use of plasma surface treatment equipment, can replace the pickling process before spraying. In terms of bonding, it is mainly reflected in the box paste machine, PP+ wood pulp and cotton bonding, LED lamp waterproof glue bonding before, car horn and buzzer bonding before, etc. Materials in these bonding processes all have a characteristic: the surface bonding strength is low, glue is difficult to bond effectively. Such as film coated cartons, UV coated cartons, the surface adhesion is low, before the general adhesion, with a grinding machine before the grinding, such as LED lamp waterproof glue before coating, are generally used to wash water and other chemicals to clean the surface before adhesive, and then coated with adhesive. Such as car parts, generally before the glue, the surface with polypropylene water, and then the glue. And with plasma cleaning equipment, can completely replace grinding machine, instead of washing water, replace PP water, in line with the national environmental protection requirements, pollution-free belongs to dry cleaning. Welding, are generally new energy battery - lithium battery, battery, pole ear soft packages, nickel surface plasma cleaned before welding, PCB micro welding surface, the bonding chips, substrate or substrates using a suitable cleaning process is very important, in the traditional solvent after cleaning, add a dry ion cleaning process, can be more effectively remove residue and oxides. The plasma cleaning technology can be used for the cleaning of all kinds of PCB through holes, pads, substrates and optical glass touch screens, including printing, bonding, spraying, inkjet, surface activation before electroplating, cleaning, coating, coating, modification, grafting, roughening, etc.
