How to prevent condensation on the wall in winter, and how to prevent freezing of cement in winter

1. When the tide returns at home, remember to close the windows at home, especially the windows facing south and southeast, so as not to give the moisture outside the window any chance to sneak in. The most important period of moisture protection is in the morning and evening, when the air humidity is higher than in the afternoon, and if the doors and windows are not closed in time, moisture will seriously penetrate into every corner of the home.

2. It is also a good practice to spread newspapers on the ground and on the table to absorb moisture in addition to preventing the doors and windows from opening doors and windows. Spread the used old newspaper on the floor and table, especially in the door and other places that are easy to get wet, you should spread two more layers, so that it has a good moisture-proof effect on the room.

3. Light candles, lighting candles can prevent water vapor from condensing, so that the room humidity can be reduced. If you already have a musty smell in your home, you can choose a candle with natural plant aromatic essential oils, which will not only dry the air, but also remove the musty smell from the room.

2. Damage to the wall by condensate on the interior wall:

Condensation will not only cause dampness in the interior walls, but if it is not solved for a long time, it will cause the walls to become moldy and black, or the decorative materials to become moldy, warped and deformed. The places most prone to condensation are around the top snorkel, plastic steel window sills, concrete ring beams and structural columns in contact with the outside. Condensation is not as inconsequential as we think it is in our daily life, and if condensation appears on the walls of your home, you should remove it as soon as possible and then solve the problem at the root.

3. Do a good job in the thermal insulation effect of the wall

1. Manufacture sandwich walls:

The sandwich wall is made by reserving the middle part of the building wall as a hollow structure, and then placing the insulation material in it, which allows the interior occupants to enjoy the effect of thermal insulation. But the cost of this kind of construction mode is relatively high, and the intermediate link is also more complicated, but the requirements for insulation materials are relatively low.

2. Add insulation structure

This insulation method is not quite the same as the construction step of manufacturing sandwich wall, that is, adding an insulation structure in the middle of the wall, and then placing the insulation material in the interior wall to achieve the effect of heat preservation. This technique is relatively simple to operate, and it is a post-production project, so you can change it if you are not satisfied.

Add salt to the cement. The role of salt is to act as an antifreeze agent, so that the concrete can be hydrated normally in a negative temperature environment from 0 to -15; Lower the ice point and improve the early strength of concrete. The antifreeze component can change the concentration of the liquid phase of the concrete, reduce the freezing point, ensure the presence of the liquid phase of the concrete at negative temperature, and make the cement continue to hydrate.

The water-reducing component can reduce the amount of water used in concrete mixing, thereby reducing the amount of ice formation in the concrete, and making the ice grain size fine plum small and evenly dispersed. <

The water-reducing component reduces the amount of water used in the concrete mixing bucket skin, thereby reducing the amount of ice formation in the concrete and making the ice particles fine and evenly dispersed.

The air-entraining component is to introduce a certain amount of tiny closed air bubbles to alleviate frost heave stress. The early strength component can improve the early strength of concrete and enhance the damage resistance of concrete to freezing. Rust inhibitors such as nitrite can prevent the rust of chloride salt on steel bars to a certain extent, and have both antifreeze and early strength.

1.How to break the condensate of the interior wall in winter?

Indoor condensate is mainly caused by the large temperature difference between indoor and outdoor, which mostly occurs in winter. When the indoor temperature and humidity are relatively high, but the outdoor temperature is relatively low, or the thermal insulation environment is relatively poor, and the air is not circulated, the cold air entering the room is easy to produce condensation. In this case, if possible, we can make a new layer of insulation indoors to strengthen the insulation effect.

Or try to minimize the amount of cold air entering the room. Remember to close the window when there is a large temperature difference between morning and evening.

2. What are the wall insulation materials?

1.Vacuum insulated panels.

Vacuum insulation panels are one of the materials with the best thermal insulation properties. It is a high-efficiency insulation board made of inorganic fiber core material and high gas resistance composite film through vacuum packaging technology and special interface mortar. With a thermal conductivity of about W (mK), it has lower thermal insulation performance than air and is the best among other insulation materials.

2.Aerogel.

The aerogel material is very lightweight and combines thermal and fire protection properties. The material is mainly nano silica aerogel, which has the characteristics of high temperature resistance, low thermal conductivity, noise resistance, and shock absorption. It is an indispensable and efficient thermal insulation material in metallurgy, chemical industry, national defense, aerospace and other fields.

3.Foamed polyurethane.

What are the wall insulation materials? Foamed polyurethane materials have the best performance among insulation materials, and can be divided into on-site foamed polyurethane and factory-prefabricated rigid foamed polyurethane sheets. It has the function of heat insulation and waterproofing, which is suitable for roof insulation and waterproofing and basement earth-covered wall insulation and waterproofing.

3. How to do simple interior wall insulation?

1.Make sandwich walls. In the middle part of the building wall, a hollow structure is reserved, and insulation materials are placed inside, so that indoor residents can enjoy the thermal insulation effect. The construction cost of this method is relatively high, and the links are relatively complex, but the requirements for insulation materials are low.

2.Add an insulating structure. The insulation structure is added in the middle of the wall, and the insulation material is pasted on the inner wall to achieve the effect of heat preservation. This method is generally carried out in the later stage of construction, and the technical operation is relatively simple, which belongs to the later stage of construction, and can be changed if you are not satisfied.
