Method for judging moisture content of building square

Square wood is often used as the main material for door and window decoration and structural construction. The performers play an important role in the decoration project. The quality of pine, eucalyptus, fir and other square wood is better, and the decorative effect is better. When buying Fangmu, you need to observe its water content. Large deformation may occur after the construction of square wood with excessive moisture content. On the one hand, it affects the appearance, on the other hand, it affects the overall safety So how do you judge the moisture content of building blocks?

First, the weight

The simple method of judging the moisture content of the building square is to touch the method by hand, that is, whether the hand is placed on the square wood to feel a strong moist feeling, but the moisture content of many square woods after drying is still large. At this time, it is difficult to judge the moisture content of the building block by the touch method, so the weighing method can be used to lift the square wood off the ground. It feels its weight in the air, and the low moisture content of the square wood is lighter, but the high moisture content of the building square will have a sharp resistance.

Second, the nail

The nailing method is an important method for judging the moisture content of building blocks, and it is also an accurate method. The specific operation is as follows: a small hammer is used to nail the long nail into the building square wood. If there is no resistance when nailing, the square wood can be pierced, indicating that the moisture content of the square wood is very low, otherwise it means that the interior of the square wood is wet. .

Third, listen to the sound

The moisture content of the better building squares is not too large, but in order to achieve the construction quality to a large extent, the dry square wood can also be selected to judge the water content by the sound of woodworking planing. If the sound of the planing is light and brittle, the surface of the rear wood after shaving is smooth and the surface has a temperature, it indicates that the performance price ratio is high. Building square wood.

Four-sided paper towel moisture determination

Choose to touch the building block, feel the wood surface will be dry, or open the wood, put a dry paper towel on the open wood surface, wait a while, check whether the paper towel has large or small wet wrinkles. Wrinkles and other situations, in fact, this is also a relatively good way to judge whether the building is dry or not.
