The dosage and specification of interface agent, and the use method of interface agent

1. Dosage: cement sand: interface agent.

1 2 Mix and stir evenly, and apply directly to the surface of the base layer to be treated.

2. Usage specifications:

1) Roller painting or mechanical spraying can be used to spray on the base layer or insulation board to be treated.

surface is sufficient. 2) The surfacing agent will be stored for a long time, and there will be delamination and mildew, so it can be stirred evenly before use, and the use effect will not be affected.

3) The interface agent should be evenly brushed and should not leak.

4) The operating environment temperature of the interface agent should be above 5.

The dosage of interface agent per square meter is about 100-150 grams.

The interface agent is suitable for the interface treatment of the base layer before scraping putty or plastering on concrete, brick-concrete wall, and is suitable for artificial "hair-making" on the wall base layer before pasting tiles, which is not only suitable for cement brushing, but also suitable for pasting wall covering.

Consumption: Theoretically, 1 kg of "Yao's Wall Solid" can be coated with 10 square meters (one time). The actual amount will vary depending on the influence of various factors in the construction.

In spring and autumn or dry weather, the new wall can be dried for 30 days; In hot and rainy weather, the air humidity is high, and it is necessary to ensure that it is dried for at least 45 days. If the wall is treated without drying, the water will slowly seep out of the painted wall, and the wall will blister and fall off.

1. The construction environment should be dry, the relative humidity should be less than 70%, and the ventilation should be good. The temperature of the base surface and the environment should not be lower than +5.

2. Base preparation: The base surface should be clean, not loose, no dust, grease, moss, carpet glue, etc. should be removed, loose and cracked parts should be chiseled and repaired in advance.

3. Stirring: Add 10 liters of water (water: powder = :1) to each bag of powder (20 kg), which must be stirred with electric equipment and stirred into a uniform slurry.

4. Brushing and drying: Use a roller or brush to apply the slurry to the base surface, without missing the brush, and then let the painted surface dry (about 12 hours).

5. Curing and finished product protection: ventilation must be strengthened, natural curing can be, and the follow-up process can be carried out only after the slurry is dry (the surface turns gray and black) and the base surface is confirmed to be completely closed.

6. Cleaning of tools: The solidified slurry is difficult to remove. After use, the tool should be cleaned with water as soon as possible.

1. The actual construction of the interface agent is generally 1 time.

2. The specific instructions are made by the manufacturer.

3. The quota specification stipulates: the concrete surface does not exceed.

The wall surface of the block does not exceed.

The waterproof concrete surface does not exceed.

Aerated concrete block is a light porous silicate product made of sand, fly ash, lime and cement as the main raw materials, mixed with aluminum powder as an air-entraining agent, through batching, mixing, pouring, pre-cursing, cutting, autoclaving, curing and other processes. Because it contains a large number of uniform and fine pores after gassing, it is called aerated concrete block.

Aerated concrete blocks have the advantages of light bulk density, high thermal insulation performance, good sound absorption effect, certain strength and machinability. There are many independent small pores inside the block, and the time required to absorb water to saturation in the same volume is 5 times that of clay bricks. There are a large number of bubbles and pores in aerated concrete blocks, mainly because of the action of adding air-entraining agent aluminum powder, and only after adding, can a lightweight and porous structure be formed.

When selecting the interface agent of aerated concrete block, it is necessary to consider that it can close the pores of the substrate, reduce the absorption of the wall, and achieve the blocking and reducing of the water in the block absorption of the plastering mortar, so as to ensure that the plastering mortar is gelled and hardened under better conditions. It plays the role of bonding and bridging between the masonry and the plastering surface, ensuring that the upper wall mortar and the masonry surface are more easily combined into a solid whole.

The interface agent used in aerated concrete blocks must have an airing time of more than 10min, and only in this way can the workability and workability be guaranteed. The shear bond strength should be greater than. After water immersion treatment, heat treatment, freeze-thaw cycle treatment, and alkaline treatment, the tensile bond strength value is greater than the value.

If the interface agent for concrete is used, that is, YQ-MR type is used on the wall surface of aerated concrete block, the wall surface will quickly absorb the water in the interface agent, after the interface agent loses water, the cement can not get sufficient hydration reaction, the strength will be very low, the bonding strength will be reduced to the inside, the significance of using the interface agent will be lost, and the role of bonding bridge will still not be played, and the effect of two-way affinity can not be realized. Therefore, when we choose an interface agent product, we must analyze what type of wall it belongs to, and after knowing the type of wall, it is very important to choose the right interface agent.

1.It can be sprayed on the surface of the base layer or insulation board to be treated by roller coating or mechanical spraying.

2.Cement sand: surfactant = 1 2 ratio mix and stir evenly, and directly coat the surface of the base layer to be treated.

Interface agents are simple to use and have two uses:

1. When the cement is used, the wall can be mixed directly into the cement and stirred.

2. Rolling the wall, remember to mix water according to the instructions, the wall of the general nest requires 50% water, of course, more and less can be. Don't think that it is better not to mix water, and the wall that does not use water means that its own effective ingredients are less, and it cannot be used if you mix water! A really good wall must be mixed with water, otherwise it will be counterproductive.

It will seal the moisture in the wall and it is not easy to dry out, which may cause the wall to bulge and crack in the later stage. After mixing with water, just roll the wall directly!

The specific use of interface agent is as follows:

1. Clean the wall: clean the peeling and loose parts of the wall, and use cement mortar to repair it, shovel the residual ash, and then sweep the wall.

2. Interface agent for interface treatment: The interface agent is made of Meichao ground wall solid. Meichao wall solid is a polymer concrete interface treatment agent.

The appearance is milky white glue. Due to the excellent permeability of the wall solid, it can fully infiltrate the surface of the base material, make the base layer compact, improve the interface adhesion, improve the bonding strength of the mortar or putty and the wall surface, and prevent hollowing.

3. Treatment of the original cracks: cut the cracks with a putty knife, as deep as possible, and fill in the caulking gypsum. Pay attention to be sure to fill it up and fill it evenly. Then use kraft paper to paste the cracked place, dry it and then scrape putty or do other processes.

1. The actual construction of the interface agent is generally 1 time.

2. The specific instructions are made by the manufacturer.

3. The quota specification stipulates: the concrete surface does not exceed.

The wall surface of the block does not exceed.

The waterproof concrete surface does not exceed.

The size of the floor slab.

The thickness of the floor slab of the residential commercial house is 10cm [within the width of the floor collapse and noise] and the size of the shouting shirt. 1。The thickness of the plate shall not be less than 1 40 of the width of the plate.

2。Width 370cm, plate width of 1 40:10cm [pass] 3.

In the case of flat plates, the thickness should be consistent.

Still don't understand. The thickness of the floor slab is different, here the floor thickness of 10-12cm reinforcement is taken as an example: the stress bar 8 spacing is 150, the distribution bar 6 spacing is 130, the upper layer negative bending bar 8 spacing is 150, and the 1 4 of the slab span is arranged along the ring beam, and the distribution bar is 6 spacing 250.

The reinforcement configuration of houses in construction, such as jujubes, is generally represented graphically. According to the reinforcement diagram, determine the position, shape and type of reinforcement used in the building. A floor slab is a type of separation load-bearing member.

The load-bearing part of the floor layer separates the house vertically into a number of leaky layers, and transmits the vertical load of people and furniture and the self-weight of the floor slab to the abutment stool through the walls, beams or columns.

What is an interface agent?

An interface agent is an adhesive, which is generally made of vinyl acetate-ethylene. It is usually used on concrete surfaces because the concrete surface is too smooth for this liquid date. By using this product, the surface of the base layer can be roughened, the adhesion to the base layer can be increased, and the plastering layer can be avoided from hollowing out.

Applied in the field of construction, there are concrete interface agents, ceramic tile interface treatment agents, building insulation board interface treatment agents, etc., which are classified as a class of interface agents using coating treatment construction methods.

Concrete interface treatment agent is a strong and flexible liquid interface agent made of polymer with special polymer emulsion as the base material and supplemented by a variety of fillers. It has permeability, cohesiveness, water resistance, air permeability and weather resistance, and can form a network system between the base layers, which solves the quality problems such as hollowing and falling off between the knots.

In fact, the interface agent is not a single one, it is divided into many kinds, so we must have an understanding of it when we buy. The above is the ** of interface agents and the different types of uses of interface agents introduced to you today, and this is the end here.
