Vermiculite for fire retardant coating
Fire retardant coating is through the coating brush on the surface of the material, can improve the fire resistance of the material, slow down the flame spread spread speed, or in a certain time can prevent combustion, this kind of coating is called fire retardant coating, or called flame retardant coating.
The basic composition of thick coated steel structure fireproof coating is: binder (Portland cement, magnesium chloride or inorganic high temperature bonding agent, etc.), aggregate (expanded vermiculite, expanded perlite, aluminum silicate fiber, mineral wool, rock wool, etc.), chemical additives (modifier, hardener, waterproof agent, etc.), water. Steel structure fireproof coating base material of Portland cement, magnesium chloride cement and inorganic binder, commonly used inorganic binder including alkali metal silicate and phosphate substances.
Because the coating of thick steel structure fire retardant coating is thick and the dosage is much, increase the weight of the building. Therefore, attention should be paid to the addition of some lightweight materials and efficient heat insulation aggregate to reduce the density of the coating. The most used lightweight insulating aggregates are mainly expanded vermiculite and expanded perlite.
Fiber (sepiolite fiber, aluminum silicate fiber, etc.) will be added to the fireproof coating in order to prevent the cracking of fireproof coating.

The construction method
Roller coating method: The roller is a hollow cylinder with small diameter and long fluff made of synthetic fiber glued to the surface. The cylinder is equipped with two washers at both ends and a hole in the center, through which the curved handle passes. When using the roller, it is first immersed in the coating and then applied to the desired surface with force. Develop a roller coating device for conveying paint with air compressor.
Brush coating method: brush coating method is suitable for brushing any shape of the object, the vast majority of fire retardant coating can be used in this method of construction. Brush coating method is easy to penetrate into the fine holes of the metal surface, so it can strengthen the adhesion to the metal surface. The disadvantage is that the production efficiency is low, the labor intensity is large, and sometimes the coating surface has brush marks, which affect the decoration of the coating.
Spraying method: The use of compressed air and spray gun to paint atomization construction method, it is characterized by uniform coating quality after spraying, high production efficiency. The disadvantage is that a part of the paint is lost, and due to a large amount of solvent evaporation, affect the operator's health. The key equipment of air spraying is spray gun. The spray gun is usually divided into gravity type, suction type and pressure feeding type according to the coating supply mode, and is divided into small and large two types according to the spraying capacity. Paint viscosity is high, need air pressure, nozzle should be selected large caliber; Low viscosity of the paint, the need for small pressure, nozzle can choose small caliber. The air pressure of air spraying is generally 0.3~0.6MPa.
Construction environment
1.It is required that the slurry with good mixture is matured for 15-25 minutes before construction to ensure that the slurry
reaches the best construction viscosity.
2 requirements according to the construction capacity to determine the preparation of paint, can be used with. The prepared coating should be used up within 120 minutes and cannot be used again after solidification.
3. It is recommended that the first construction use spraying construction method, coating thickness is not more than 5 mm, the second time can be sprayed or coated, coating thickness is not more than 10 mm each time is appropriate, each time interval is 24 hours, until the design thickness is not less than 13.3 mm.
3. It is recommended that the first construction use spraying construction method, coating thickness is not more than 5 mm, the second time can be sprayed or coated, coating thickness is not more than 10 mm each time is appropriate, each time interval is 24 hours, until the design thickness is not less than 13.3 mm.
4. The ambient temperature at the construction site is 5-38 ° C, and the relative humidity is no more than 85%. The curing period of physical and chemical properties inspection is 28 days, and the curing period of fire resistance inspection is 40 days.
5 such as in the outdoor brushing, the basic drying of the coating, must be coated on the surface of the fire retardant coating brush acid resistant, alkali modified acrylic paint to protect.
6. The undried coating shall not be hit, washed and rained
