Coating standard: quality inspection and relevant inspection standards after coating

Core tip: quality inspection after coating The quality of coating must be reflected in the quality of coating film Therefore, the quality inspection after coating mainly includes the inspection of coating film performance, including mechanical performance (such as adhesion, flexibility, impact strength, hardness, gloss, etc.) and special performance with protection function (such as weather resistance, acid and alkali resistance, oil resistance, etc.) Mechanical performance is the basic routine performance that must be tested in coating quality testing, while the special performance with protection function can be selectively tested according to different use requirements Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Coating home news: the quality inspection after coating the quality of the coating must be reflected in the quality of the coating film, so the quality inspection after coating is mainly the performance inspection of the coating film, including the coating machinery Performance (such as adhesion, flexibility, impact strength, hardness, luster, etc.) and special performance with protection function (such as weather resistance, acid and alkali resistance, oil resistance, etc.) Mechanical performance is the basic routine performance that must be tested in coating quality testing, while the special performance with protection function can be selectively tested according to different use requirements The quality inspection after coating is the final basis to evaluate the coating quality and an important link to ensure the quality The standard inspection methods related to the quality inspection after coating are as follows (1) Gb1720-89 (79) test method of film adhesion; (2) test method of film flexibility; (3) test method of film impact resistance; (4) test method of film hardness Pendulum damping test; (5) pencil test method of film hardness (GB / t6739-1996); (6) test method of film adhesion (gb5210-85); (7) test method of film gloss (gb1743-89 (79); (8) Gb1768-89 (79) determination of abrasion resistance of paint film; (9) gb1769-89 (79) determination of burnability of paint film; (10) gb1770-89 (79) determination of burnability of primer and putty film; (11) grid test of varnish and paint film; (12) gb6742-86 bending test of paint film (cylindrical axis); (13) GB / t1733-93 determination of water resistance of paint film; (14) GB / t1734-93 determination of vapor and oil resistance of paint film; (15) Gb1735-89 (79) determination of heat resistance of paint film; (16) gb1738-89 (79) determination of water absorption of insulating paint film; (17) gb1739-89 (79) determination of oil resistance of insulating paint film; (18) gb1740-89 (79) determination of damp heat resistance of paint film; (19) gb1741-89 (79) determination of mildew resistance of paint film; (20) gb1761-89 (79) determination of pollution resistance of paint film; (21) gb1763-89 (79) test method for chemical reagent resistance of paint film; (22) GB / t1766-1995 rating method for aging of paints and varnishes; (23) GB / t1771-91 test method for neutral salt spray resistance of paints and varnishes; (24) gb1865-89 (80) test method for aging of paint film (artificial acceleration); (25) gb5370-85 test method for shallow sea immersion of antifouling paint sample; In the above test items, the user shall prepare standard test samples according to the general preparation method of the paint film described in the previous section, and test the most conventional mechanical and physical properties of the film to judge the basic performance of the film Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
