General knowledge of coating: precautions for construction of high temperature and rainy wood paint in summer

Core tips: 1 The control of construction environment temperature wood paint construction requires the temperature, humidity and ventilation conditions of the construction environment If the construction does not meet the construction conditions, the final paint film may have serious disadvantages The best temperature of construction environment is 25 ℃, the highest temperature shall not exceed 35 ℃, and the highest humidity shall not exceed 85% The construction shall be stopped when the temperature exceeds 35 ℃ and / or the humidity exceeds 85% In addition, the construction site shall be well ventilated 2 The viscosity of construction paint shall be controlled The viscosity of paint of the same quality in summer is lower than that in winter Therefore, the viscosity of paint shall be controlled according to the 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 Paint Home News: 1 The control of construction environment temperature wood paint construction requires the temperature, humidity and ventilation conditions of the construction environment If the construction does not meet the construction conditions, the final paint film may have serious disadvantages The best temperature of construction environment is 25 ℃, the highest temperature shall not exceed 35 ℃, and the highest humidity shall not exceed 85% The construction shall be stopped when the temperature exceeds 35 ℃ and / or the humidity exceeds 85% In addition, the construction site shall be well ventilated 2 Viscosity control of construction paint The viscosity of the paint of the same quality is lower in summer than in winter Therefore, the construction viscosity of the paint shall be adjusted according to the temperature during construction by adjusting the adding proportion of diluent Generally, the paint shall be sprayed with PU primer for 9-11 seconds, NC primer for 9-14 seconds, Pu primer for 2-16 seconds, NC primer for 2-15-18 seconds, Pu finish for 11-13 seconds and NC finish for 10-12 seconds However, it should be noted that if the ambient temperature is too high and the amount of diluent is not enough, the quality of the paint film may eventually be affected Therefore, before the actual construction, the ratio test of paint and diluent should be carried out in advance, and the ratio should be carried out on the premise that the paint film will not have defects 3 Thickness control of construction paint During coating construction in summer, due to the high weather temperature, thick coating is not suitable during spraying, because the paint solvent volatilizes rapidly, resulting in relatively fast surface drying speed, and the coating film is thick, so it is very easy to cause defects such as prickles, bubbles and pinholes on the surface of the coating film The construction personnel shall fully consider the climate factors during construction, and make reasonable arrangements to avoid unnecessary problems Life Solutions to problems in summer construction the home of coatings is focused on coatings, diatom mud, paint coating, coating process, news and information of fire retardant coatings, coatings, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fire retardant coatings,
