What are the waterproofing standards and practices for grain warehouses?
Method:
1
First, take moisture-proof measures on the ground and use No. 10 construction petroleum asphalt. Use medium heat to boil asphalt and use two pots at the same time. One pot dissolves the asphalt filter residue; the other pot boils the asphalt to dehydrate it. The temperature control of asphalt boiling should be determined according to the asphalt model to prevent carbonization during asphalt boiling.
2
Then the ground base layer is processed. The base layer needs to be completely dry. It will take a long time to dry thoroughly. After the foundation project is completed, the soil should be filled and compacted immediately, and the three-component soil cushion layer should be laid. Build walls. The cushion layer must be dense, flat, protected, and painted evenly.
3
It is better to use a brown brush or a bristle brush for asphalt painting with pure asphalt. The specific operation method is to use an iron spoon with a diameter of 10 centimeters, and apply one to three times for each spoonful. Do not paint back and forth multiple times. It must be thin and even. Use about 4 kilograms of asphalt per square meter.
4
Put some desiccant to prevent moisture in the grains in the granary. Do not put anything around that is easily affected by moisture. Spread a few more layers of plastic, and then put desiccant directly under the grain.
5
Moisture-proof measures should be taken on the ground. The pavement layers should be made of 4 cm thick No. 150 plain concrete slabs. They can be precast or cast-in-situ. Each precast slab is 1 square meter. should. Use 1:3 cement mortar to set the grout. After laying the boards, use 1:2 cement mortar to smooth the joints.
6
Waterproof and moisture-proof construction of the wall base. The waterproof and moisture-proof construction of the wall base can be done by laying the feet in a stepping shape to prevent the pressure from the grain storage side from pushing the wall. Before painting the asphalt, the wall should be primed with 1:3 lime mortar, compacted and smoothed, then painted with a layer of asphalt, the thickness should be uniform, and finally a layer of lime milk should be painted on the surface.
Do grain silos need to be waterproofed?
Food is related to the country’s people’s livelihood. Therefore, for the safety of national grain reserves, granaries should have functions such as waterproofing, moisture-proofing, heat preservation, and air tightness. Therefore, waterproofing and moisture-proofing is key. If waterproofing is not done, after the grain is stored, the bottom or the corners and top of the silo will become damp or leak, which will increase the moisture content of the local grain and cause mold and agglomeration of the grain. cause losses.
How to make the corn barn waterproof and moisture-proof?
Answer: Place plant ash at the bottom of the corn bin to keep it from getting wet. This is a simple and easy solution. Plant ash has excellent moisture insulation effect. The specific operation method is: put about five centimeters of dry plant ash at the bottom of the corn bin, separate it with a plastic sheet on top of the plant ash, then put in the sun-dried corn kernels, leave a five centimeter gap at the top of the jar, then put in the grass and grass and cover it. , does not get wet up and down, and can also prevent insects and rats.
What kind of waterproof coating should be used when water penetrates from the top of the warehouse?
Use two-component waterproof materials
(1) When using two-component waterproof coatings, component A and component B should be stirred evenly before preparation, and then strictly follow the materials The material mix ratio provided by the supplier must be accurately measured; the quantity of each preparation should be calculated and determined according to the coating area each time, and prepared as needed; when mixing, pour component A and component B into the container and use a portable electric Stir vigorously with a mixer until evenly mixed and ready to use.
(2) Before using the one-component waterproof coating, just stir it evenly before use.
How to prevent moisture in an iron granary?
1. The air in the rainy season is humid and many things are difficult to dry. Therefore, you should pay attention to moisture-proof measures in the warehouse. According to the situation, use less wet rags and wet mops to clean the warehouse and use more dry rags and dry mops.
2. Because water vapor in the air easily condenses into water droplets when encountering tiny particles, it is necessary to keep the goods and floors clean and free of dust to reduce the formation of water droplets on the surface.
3. Observe the humidity in the warehouse. When the humidity inside the warehouse exceeds the humidity outside the warehouse by more than 15 degrees, open the ventilation windows, ventilation slots, etc. in time for ventilation, and close them otherwise.
4. Lime is used as an adsorbent. 1 kilogram of quicklime can absorb about 0.3 kilograms of moisture in the air. In rainy and humid weather, quicklime can be packed in cloth or sacks and placed in every corner of the warehouse to keep the air in the warehouse dry.
5. Powerful fans can be turned on in small warehouses to enhance air convection in the warehouse and reduce condensation of water droplets. Warehouses with exhaust fans should keep the fans on.
6. Wrap the waterproof beads with a film, because it cannot be completely sealed, and there will still be a lot of water vapor under the film. After the water beads form, they are difficult to evaporate because they are wrapped in the film, and mold is prone to appear. .
7. When checking the goods, you should carefully check the sealing tape on the outer box of the goods. When the surface of the goods gets damp, tiny water droplets will appear on the sealing tape. Once found, employees must be organized to wipe it and use dehumidification. measure.
8. The goods must be placed on pallets and cannot be stacked directly on the ground. For warehouses where pallets cannot be obtained in a short time, the stacks must be turned over regularly, because the goods in contact with the ground cannot volatilize due to the penetration of ground water vapor. , condenses into water, and over time, the outer box of the goods will become severely moldy.
9. Carton goods should not be stacked too densely, but should be as loose as possible. If they are too dense, air convection will be limited, and it is easy for moist air to accumulate for a long time.� mold growth.
10. For heavier goods, the stacking height should be reduced as much as possible. If the stacking height is high, the outer box will become soft due to moisture and the bearing capacity will decrease. It is easy to cause the corners of the outer box to break due to heavy pressure. </p
