    Core tip: Product Introduction: Self repairing waterproofing coating (nanoscale silicon series) is a new high-performance product with high elasticity polymer emulsion and inorganic nano materials After drying and curing, the elastic elongation of the film is over 300%, which basically meets the requirements of thermal expansion and cold shrinkage under normal conditions Once the coating is damaged by accident, it will produce holes and cracks, which can self repair after encountering water, stop water with water, and keep water-proof function for a long time This product is composed of two parts, one is liquid material, the other is powder material It should be mixed evenly and stirred fully It is a better defense at this stage 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 Paint Home: Product Description: self repairing waterproof coating (nano silicon series) is a new high-performance product with high elasticity polymer emulsion and inorganic nano materials After drying and curing, the elastic elongation of the film is over 300%, which basically meets the requirements of thermal expansion and cold shrinkage under normal conditions Once the coating is damaged by accident, it will produce holes and cracks, which can self repair after encountering water, stop water with water, and keep water-proof function for a long time This product is composed of two parts, one is liquid material, the other is powder material It should be mixed evenly and stirred fully It is a better waterproof coating at present Self repairing coating is a kind of name that can be called "only coating" put forward in the 1990s It often refers to the organic polymer coating with self repairing function after the coating is damaged Classification of self repairing coating: Principle: this kind of repair mainly depends on providing external conditions, such as water, oxygen and carbon dioxide, etc to provide expandable components in the coating, so as to achieve the purpose of self repairing Base course treatment: the construction surface must be dry; the floating ash, impurities and oil stains on the construction surface must be cleaned up, and the convex potholes, loose and honeycomb parts with the convex and concave amount exceeding ± 10 mm of the reference plane shall be repaired and leveled with nano silicon impermeable plugging agent or cement Theoretical dosage: 1kg / ㎡ for the first time, 2kg / ㎡ for the second time Construction method: mix the two components of a and B on site before construction, fully mix them until there is no powder particles, and then use them up within 1 hour During construction, paint twice along the crack direction, 1kg / ㎡ for the first time and 2kg / ㎡ for the second time During the first application, rub back and forth to ensure that the coating and the base are well bonded and free of bubbles, and try to make the coating penetrate into the gap; during the second application, press the brush lightly to ensure that the coating has a certain thickness The width of painting along the joint shall not be less than 0.2m, to ensure that there is a certain joint surface between the coating and the base, and to reduce the possibility of coating After the film is dried, a layer of JS waterproof emulsion or cement mortar protective layer with glass fiber cloth shall be applied on the surface For the ground directly paved with floor tiles, the protective layer may not be used, but attention shall be paid not to damage the waterproof coating during construction During the construction of roof expansion joint, the floating dust and garbage in the reserved groove shall be cleaned first, and then the prepared coating shall be poured in the groove with a thickness of no less than 10 mm; after drying and curing, the expansion joint can be sealed with polymer mortar When the roof downpipe and toilet pipe mouth are sealed, a ring groove shall be opened around the pipe, and the coating shall be poured in a clean groove with a thickness of not less than 10 mm After drying and curing, it can be sealed with "nano silicon impermeable plugging agent" Precautions: 1) component a of the coating is organic liquid material, volatile, with slight solvent smell and certain flammability It must be sealed and packed with solid iron containers to prevent leakage; it must be kept away from fire source and high temperature during construction, storage and transportation, and must be equipped with qualified dry powder fire extinguishers 2) The construction site shall be well ventilated; the construction personnel shall wear latex gloves, protective glasses, work clothes and avoid the liquid materials contacting the skin during operation Be careful not to splash on the face, especially in the eyes, otherwise wash it with water or ask a doctor for treatment Storage: the self repairing waterproof coating must be sealed and stored to prevent rain, exposure and damage of the packaging container; the storage and transportation environment temperature is 0-25 ℃, and the shelf life is 12 months 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,
