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.
Can polypropylene adhesive powder be used as ceramic tile adhesive?
Polypropylene adhesive powder combined with polyethylene propylene and polyester composite waterproofing membrane can be widely used in roof waterproofing, basement, bathroom waterproofing and leakproofing, ground moistureproofing, thermal insulation and air insulation, and water wall waterproofing decoration; it can also be used It is used in waterproofing and leak-proofing of channels, pools, and dams, as well as waterproofing and moisture-proofing in food depots, grain depots, cold storages, and factory workshops. Cannot do tile adhesive.
What kind of glue is used to glue the tunnel waterproof board?
You can use PVC waterproof membrane with adhesive. The main raw materials of adhesive are natural rubber, resin ester, solvent, etc. High-strength special PVC adhesive can be used when laying large areas, and hot air welding machines can be used to weld edge sheets. PVC waterproofing membranes have a wide range of applications and can be used in various types of roof waterproofing in industry and construction, as well as in building waterproofing projects such as basements, reservoirs, road tunnels, air-raid shelters, and grain depots.
What is the national standard for air barrier films?
The vapor barrier membrane is laid between the roof base and the insulation layer, which can enhance the air tightness and water tightness of the building and slow down the discharge of water vapor and indoor moisture in the concrete structure to the insulation layer. The relevant provisions of the "Specifications" on the vapor barrier layer: The material of the vapor barrier layer is not only required to be waterproof, but also to isolate the penetration of steam. Therefore, it is stipulated that the vapor barrier layer should be made of materials with good air tightness and water tightness.
Basic information
Chinese name
Vapor barrier film
Basic introduction
Vapor barrier film concept:
Dike vapor barrier film is made of metal coating film + polyethylene film + fiber braid + plastic film laminated with hot melt adhesive. The vapor barrier film has the functions of vapor impermeability, waterproofing, and moisture-proofing.
The vapor barrier membrane is laid between the roof base and the insulation layer, which can enhance the air tightness and water tightness of the building and slow down the discharge of water vapor and indoor moisture in the concrete structure to the insulation layer.
When used in conjunction with the waterproof and breathable membrane above the insulation layer, the vapor barrier film can effectively discharge water vapor, protect the thermal performance of the building envelope, prevent the growth of roof mold, and improve the indoor air quality. Thereby achieving the purpose of saving energy consumption.
Relevant provisions for vapor barrier layers in the "Specifications":
"Technical Specifications for Roofing Engineering" page 98 4.2.6:
my country's latitude above 40° In northern winter heating areas (cold areas), buildings with indoor air humidity greater than 75%, or buildings with annual indoor air humidity greater than 80%, will have condensation, and moisture will penetrate into the insulation layer through the roof panels, so this article stipulates:
The material of the vapor barrier is not only required to be waterproof, but also to isolate the penetration of steam. Therefore, it is stipulated that the vapor barrier should be made of materials with good air tightness and water tightness. According to practice, the vapor barrier layer is buried and pressed by the insulation layer. In order to improve the ability to resist the deformation of the base layer, the roll material of the vapor barrier layer should be laid using the empty laying method.
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 is the difference between polyurethane and styrofoam?
The concepts of the two are different
Foam rubber is a relatively special product.Product, the main raw material is polyurethane. It cures quickly when it reacts with moisture in the air, forming air bubbles that seal against water. The foaming agent is a single-component polyurethane product. After reacting with moisture, it will form a porous state and be put into use.
The ingredients of the two are different
The ingredients are different, which is the biggest difference between the two. One of the raw materials of foam rubber is foaming agent, but it is not suitable for use alone and needs to be combined with other substances. The foaming agent is an independent and simple product with good surface activity and plays a filling and sealing effect. You can feel more at ease by cooperating with powerful suppliers, such as Cosmo, which focuses on foam rubber research and provides customized foam rubber application solutions. It has a wide range of uses and can be used in new energy, military industry, medical, aviation, shipbuilding, and electronics. , automobiles, instruments, power supplies, high-speed rail and other industries.
Is waterproof glue expensive at 60 per pound?
Bathroom leak-proofing and glue-filling costs RMB 60 per kilogram, which is relatively expensive. Some companies can quote prices at random. One square meter seems to cost tens of dollars. When the glue is poured, the builder will inject several more glues. Ten or even hundreds of kilograms make money from this.
In addition, grouting is generally only used to plug cracks. It is only effective for about 3 years and is not suitable for bathrooms. It is mostly used in large-scale leak-proofing construction such as roofs, tunnels, and basements.
As for waterproofing and sealing leaks in family bathrooms, it is better to prevent them than to prevent them. It is still recommended that you give priority to waterproofing. </p
