Coating knowledge: introduction to acrylic waterproof coating

Core tip: high elastic waterproofing coating is a high performance waterproofing coating made of high-grade acrylic emulsion as raw material, with various auxiliaries and fillers as scientific basis It is an upgraded product of ordinary waterproof coating Due to the addition of a variety of polymer additives, the waterproof performance of the product is better than that of ordinary waterproof products At the same time, it has high tensile ductility and can cover cracks Product features: 1 It is highly elastic, can resist slight vibration of buildings, and can cover cracks less than 8mm caused by thermal expansion and contraction, cracking, sinking and other reasons; 2 It can be directly constructed on the wet base surface, suitable for the corner of the wall and the water seepage part around the pipeline; 3 It has strong adhesion 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 Coatings home: high performance waterproofing coating is a high performance waterproofing coating made of high-grade acrylic emulsion as raw material, with various auxiliaries and fillers as scientific basis It is an upgraded product of ordinary waterproof coating Due to the addition of a variety of polymer additives, the waterproof performance of the product is better than that of ordinary waterproof products At the same time, it has high tensile ductility and can cover cracks Product features: 1 Highly elastic, able to resist slight vibration of the building, and able to cover cracks less than 8mm caused by thermal expansion and contraction, cracking, sinking and other reasons; 2 Can be directly constructed on the wet base surface, suitable for the corner of the wall and the water seepage part around the pipeline; 3 The active ingredients in the coating can penetrate into the pores and microcracks in the cement base surface and produce chemical reaction, which can be integrated with the base material to form a layer of crystalline and dense waterproof layer; 4 Environmental protection, non-toxic and harmless, which can be directly used in drinking water engineering; 5 Acid, alkali and high temperature resistance, with excellent aging resistance and good corrosion resistance; It can be used outdoors and has good weather resistance Scope of application: it is suitable for waterproof, anti-seepage and moisture-proof of roof, toilet room, basement, water reservoir and wall Base surface treatment: ordinary base surface 1 The surface must be flat, solid and clean, free of oil, mold release agent, floating dust and other loose animals; 2 Repair large holes and cracks with repair mortar first; 3 Professional sealing treatment is required before construction; 4 Epoxy resin or similar materials are recommended to be used for sealing screws and bolts first; 5 Before using the KSF high elastic waterproof slurry, the base surface must be fully wetted with clear water, but at the same time, there must be no ponding; 6 For loose and porous base materials, especially cement fiberboard, etc., the interface treatment must be carried out before the application of waterproof slurry Construction process: 1 Pour the liquid additive into a clean mixing container, then slowly add the powder while mixing according to the proportion, and fully mix for 3-5 minutes until a uniform mortar without powder is generated, and use up within the operation time It is recommended to use mechanical mixing (400-500 RPM) to obtain the best mixing effect; 2 Evenly brush the slurry on the treated substrate with roller and brush, and brush two or more layers according to the use environment and performance requirements; the thickness of waterproof layer of general engineering is 1mm, and the thickness of underground engineering construction specification is 1.5-2mm; 3 After finishing the first layer, the second layer must be made after it is slightly dry (rigid or not sticky), which generally takes 1-3 hours, depending on the compactness of the base surface and the temperature at that time If the coating has been cured for more than 24 hours, the surface must be moistened with clear water when the second layer is applied on it; 4 Curing: from the second day after the slurry is applied, it is recommended to cover the coating with fine mist spray or wet cloth for 2-3 days, and then carry out closed water test; for the pool with long-term water, it should wait for two weeks before it is filled with water; 5, stir the size of the slurry should normally be used in 1 hours, the coagulant material can not be reused; 6, do not mix with water mixing, do not change the proportion of emulsion at will Cleaning: immediately clean all tools and equipment with water after construction, and use mechanical method to clean the solidified slurry Precautions: 1 The construction temperature shall be between 5 ℃ and 35 ℃; 2 The prepared slurry shall be used up within 1 hour; 3 Pay attention to the antifreeze storage of the product in cold area or low temperature, and the storage temperature of liquid components shall not be lower than 0 ℃; 4 Do not mix water or other materials into the product when using; 5 Take appropriate protective measures, such as gloves, etc during construction Shelf life: the original sealed product is stored in a dry and cool environment Under normal storage and transportation conditions, the shelf life of the product is one year Reference dosage: when the thickness of waterproof membrane is 1.0mm, the theoretical dosage is about 1.5 - 2.0kg/m2 Dosage refers to the total amount of powder and liquid The actual dosage depends on the specific base level Executive standard and product quality grade: GB / t23445-2009 coatings home is specialized in coatings, diatom mud, paint coating, coating process, news and coating of fire retardant coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fire retardant coating,
