Hebei high temperature glass flake cement chimney anti-corrosion materials and construction

Resin glass flake cement (coating)
, glass flake primer
) Take the pre-prepared appropriate amount of primer, then add the appropriate proportion of matching curing agent and mix the above, stir evenly before use. Use a brush or roller to apply the paint, and apply about a meter. Apply the first coat of primer to the prepared surface to be lined. And apply a second coat of primer after the first coat of primer. The directions for applying primers should be perpendicular to each other.
) During the construction of steel structure foundation, during the process of mixing primer and rubber, quartz powder should be added with a weight ratio of resin (about mesh) to achieve a better interface bonding effect.
/>) During concrete foundation construction, if the viscosity is slightly high or in a low-temperature construction environment, in order to increase the bonding between the coating and the base layer, an appropriate amount of solvent can be added to dilute it. The solvent is styrene, and the primer can be applied all over. .
, Glass flake cement mid-coat
) The mid-coat resin should match the base coating resin. The viscosity of glass flake coating is generally to, the thixotropic index is to, and the thickness of each layer is about 0, depending on the construction method. It varies depending on the situation. The construction can be done by rolling, brushing or spraying. High-pressure airless spraying should be used for spraying.
) When preparing glass flake paint, a stirrer with a higher rotation speed should be used. Add an appropriate proportion of matching curing agent and stir for more than 10 minutes. The flake glue paint stirred at one time should be used up within the time limit, and the initial setting should be done. The time should be controlled around.
) After the previous one is dry, proceed with the next one. The dosage is about 10 meters. The painting direction of the paint should be consistent, and the painting direction between the two layers should be vertical. The coating should be even, no missed coating is allowed, and there should be no sags, bubbles, pinholes, debris (bristle, sand, etc.), and no other defects are allowed. .
) Apply a layer of chopped strand felt to the uneven surface and structural corners for local reinforcement. Use a roller to apply a layer of paint and then add a layer of glass felt. After soaking, use a paint-impregnated roller to remove the bubble. Then carry out construction according to the above construction requirements.
, Resin glass flake coating top coating
Since corrosive media directly contacts the outer surface of the coating, the top coating resin must have excellent corrosion resistance and minimize the amount of filler. At the same time, the topcoat also plays a role in beautifying the appearance of the coating and increasing its impermeability. When preparing the coating, add an appropriate proportion of the matching curing agent and stir for more than 10 minutes before construction. Generally, the dosage is about 100 meters. The last coating should contain styrene paraffin liquid.
