    Core tip: the quality of coating must be reflected in the quality of coating film

    Therefore, the quality inspection after coating is mainly to inspect the performance of coating film, including the mechanical performance (such as adhesion, flexibility, impact strength, hardness, gloss, etc.) and the special performance with protective function (such as weather resistance, acid and alkaline 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

    Quality inspection after coating is the final basis and confirmation of coating quality evaluation Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively

    The feature of the breathing wall is obvious

    When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity

    It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively

    The feature of the wall that can breathe is obvious

    When the indoor air is relatively dry, the wall of diatom mud will absorb the water Coating home news: the quality of coating must ultimately be reflected in the quality of the coating film, so the quality inspection after coating is mainly to test the performance of the coating film, including the machinery of the coating film 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
