a. Remove the oil, dust, anticorrosive material and crushing layer from the original ground, remove the loose and corroded plutonium and expose the solid plutonium.
b. The exposed steel bars shall be rusted and coated with steel rust inhibitors, and shall be painted on the surface of the steel to dry them in the damp place. (20mm deep grassroots moisture content <6%);
c. Leveling as required with ramming or grabbing materials;
d. Use repair mortar or antiseptic mortar for slope or nozzle. Floor drain, etc.
2. Floor structure:
Surface: 80 thick granite plate. Ash seam width 2～3mm
Combination layer: furrow cavity mud thickness 6mm
Isolation layer: Furan fiberglass two bottom two cloth
Two epoxy resin primers
Find slope: repair mortar for slope
Leveling layer: repair material leveling
Interface agent: A YJ-302 interface agent together
Floor: Pretreatment
3.. The use of construction materials and preparation;
a. Use YJ series or xLz furfural resin to prepare the glue solution, the ratio is: furan liquid: furan glass steel powder = 1:1 (YJ type) or 1:0.3～0.5 (XLz type):
b. Glass fiber cloth: It is a commonly used glass fiber product. It is reinforced with glass fiber reinforced plastic. It is made of alkali-free and wax-free roving glass fiber checkered plain cloth. The thickness is 0.2~0.4mm, and the warp and weft density is 4*4~8*8/cm2. The number of yarns is convenient for molding, good deformability, moderate price, smooth surface, compactness, and good airtightness.
c. Furan cement ratio: (YJ type) furan liquid: furan powder = 1:3.54 or (xLz type) 1:3 ~ 4;
d. Block: 400 × 4QOx80mm igneous rock granite. SiO2 content 60% ~ 7o%, specific gravity 2.6 ~ 2.8, compressive strength 240N/mm2 or acid-resistant brick (board);
e. Base material: Epoxy fiberglass base material. Cementation: thinner: curing agent = l: 0.6 ~ 1: 0.06 ~ 0.08.
4. Construction operation procedures:
a. The construction of the grass-roots level according to the method of treatment:
b. 2. Prepare a thin and even coat of two coats with a formulated epoxy glass steel primer. After curing for 24 hours, the construction of FRP can be carried out:
c. The construction of the second bottom and the second cloth:
(1). Brush a rubber on the base layer. Then use a brush or wool roller to cover the glass fiber cloth. To make the base rubber,
The glass fibers are closely attached to each other, and at the same time the excess rubber and layers are squeezed out and naturally cured for 12 hours:
(2). When not sticky. Check the quality of the patch and trim it. In the direction perpendicular to the lower glass fiber cloth paste. Continue to follow the above method for construction. After natural curing for 12 hours, the construction of the second floor and the second floor can be completed:
(3). The lap width of the glass fiber cloth should not be less than 50mm, and the overlapping of each layer should be staggered:
(4). In the equipment corners, takeovers, inlets, floor drains, etc., the force and the medium scouring parts need to be reinforced with 1 or 2 layers of glass cloth.
d. Before the block construction. Should do a good job:
(1). The blocks will be tested or the specifications will be 'Blank:
(2) Wipe a 1 to 2 mm thick protective layer on the isolation layer to protect the isolation layer. After solidification, proceed with the block construction:
e. The use of kneading extrusion block construction. Ensure that the mortar seam and bonding layer are full and dense;
f. After part of the block construction, before the final coagulation of the mud. Pay attention to filling and smoothing the gray seam to ensure that the seam is dense, smooth, and smooth:
h. It can be used for curing for 14 days at room temperature. When overhauling, it can be used to increase the local temperature of the environment and strengthen the ventilation measures to shorten the curing time:
i. According to "Building anti-corrosion engineering construction and acceptance specifications" for quality inspection and acceptance.
Concrete construction treatment method for floor maintenance
1. Before doing anti-corrosion construction, please do some pre-conditioning work:
