Common knowledge of coating: what should be paid attention to in spraying construction management

Key tips: the following problems should be paid attention to in the spray construction management: (1) After the base course meets the coating construction requirements for decorative coating ① Before ordering, the area and quantity shall be calculated in detail, so as to make sure that the coating of each color is enough at one time In case of supplement, it shall be the same as the sample color The manufacturer shall have the color sample and the sample made during the actual construction, and mark the color number and the factory batch number on the packaging barrel ② The general coating is allowed to be stored for 6 months, and it is required to be stored in a dark warehouse at 15-20 ℃ In summer, direct sunlight in the open air shall be avoided, so as to prevent the viscosity from becoming smaller, and it is easy to flow and grow during construction Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Coating home news: the following problems should be paid attention to in the spray construction management: (1) after the base layer meets the coating construction requirements for decorative coating ① before ordering, the area and dosage should be calculated in detail, so as to make sure that the coating of each color can be ordered enough at a time, in case of supplement, it should be the same as the sample color The manufacturer shall have the color sample and the sample made during the actual construction, and mark the color number and the factory batch number on the packaging barrel ② The general coating is allowed to be stored for 6 months, and it is required to be stored in the dark warehouse at 15-20 ℃ In summer, direct sunlight in the open air shall be avoided, so as to prevent the viscosity from becoming smaller, and it is easy to flow and grow mold during construction In winter, low temperature will cause the problems of poor hardening, bulging and falling off, so low temperature storage shall be avoided ③ The coating must be stirred evenly before use, and the two-component coating should be fully stirred evenly before use It is not allowed to mix materials other than those specified by the manufacturer into the coating (2) The distance between the scaffold and the construction surface from the wall surface is 50-60cm, the distance between the scaffold and the construction surface is 40-50cm, the distance between the scaffold and the construction surface is 1.6-1.9m, and the distance between the scaffold and the construction surface is 1.9-2.2m In addition to the distance, special attention shall be paid to the protection of doors, windows and finished products, and all construction parts shall be enclosed with shielding cloth (3) Before spraying the scaffold, the dust on the scaffold shall be cleaned to prevent the wall from being polluted in the spraying process; pay attention to the parts between the upper and lower layers of scaffolds, and the overlapping parts of plastering and spraying shall not be placed in the same position, which shall be staggered; when spraying the joint parts of the upper and lower layers, the spraying shall be carefully conducted from the bottom of the scaffold to the top to avoid one deep and one shallow one Or the horizontal non-uniform phenomenon of hanging ash When the spraying area is large, the grid joint shall be made, and the coating joint shall be placed on the grid joint, so that the decoration effect is easy to be uniform (4) Weather factor ① the general wind speed is more than 5m / s, so it is not suitable to spray construction The wind speed increases about 1 m / s for every 10 m increase of buildings Strong wind will reduce the strength of the coating film, resulting in uneven spraying, uneven color and luster The solvent coating is easy to fire when encountering Mars ② The impact of rain should not be drenched 24 hours before spraying and 12 hours after spraying, because most of the building coatings are water-based, and cannot encounter water before film forming The influence of temperature generally stipulates that the lowest construction temperature of synthetic resin emulsion building coating is 5 degrees C If the temperature is up to 40 ℃ and the base temperature is up to 45 ℃, the coating will become thinner and prone to flow, bubble, wrinkle and even crack, resulting in uneven color Moreover, if the temperature is too high and the water evaporates rapidly, the adhesion and fastness of the film will be seriously affected 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,
