Woodworking material selection and construction considerations

Carpentry projects, in the renovation project, often belong to a large category. Here, we introduce the knowledge about carpentry. From a renovation point of view, basically, carpentry represents decoration, more than construction. It can be seen that woodworking in the decoration industry's weight. Many owners, including owners of tooling and home improvement, will consider the craftsmanship of carpentry as the basic level of a decoration company. Therefore, most of the decoration companies will regard carpentry as the top priority.

Carpenter's quotation is not comparable to other renovation projects due to factors such as materials and design. We take a look at a simple wardrobe:

1. Scenario 1: Use a density board structure with veneer inside and veneer outside.

2. Scenario II: Use big core board structure, internal brush varnish, and external brush mixing oil.

3. Solution 3: Use a large core board structure with a beryl board inside and a veneer with a veneer.

4, program four: all solid wood structure, add varnish or mixed oil.

From the above four methods, it is theoretically feasible, but the cost is very different. The cost of Option 3 may be more than twice as much as the cost of Option 1, plus the difference in design, the comparability is even lower.

First, the main board technology

1, density plate technology

MDF can be divided into high density board, medium density board and low density board. Most commonly used in the dense plate. This process is most welcomed by furniture factories and professional companies (such as kitchen companies). This process depends on the suppression of the machine and the possibility of on-site construction is almost zero. Therefore, decoration companies are rarely used.

The MDF process relies mainly on component assembly. On the other hand, its finish is mainly applied instead of nailing. This paste is different from on-site production, it is mainly used to suppress the machine. When combining density materials such as density boards and fireproof boards, it can often produce quite good results.

The most important drawback of the MDF process is the large expansibility. After water, it is almost hopeless. Another disadvantage is the poor bending resistance, which cannot be used for high-stress projects.

2, big core board structure

Daxinban is currently the more popular material, and Utah is a decoration company. Heart-shaped heartwood has a certain strength, and when the size is relatively small, the effect of using a large core board is better than that of other artificial boards. Of course, the construction technology of Daxinban is basically the same as the construction technology of modern woodworking. The construction is convenient, fast, and relatively low-cost, so it is more and more loved by decoration companies. The process of the large core board mainly uses nails. At the same time, it is also suitable for simple viscous pressure processes.

The main drawback of Daxinban is its poor horizontal bending performance. When it is used as a bookcase and other projects, its large distance strength often fails to meet the weight requirements of the book. The solution can only be the narrowing of the bookshelf.

3, solid wood board

Solid wood practices are traditional practices. Due to the large number of types of wood, the difference in effect is great, but the process is similar. Solid wood panels have the advantages of good bending resistance, high strength, durability, and good decorative effect.

Solid wood practice uses traditional techniques and rarely uses nails, glue, and other practices. The skill requirements of carpentry workers are high, and carpenters who have not been formally trained are hard to do the job. Before the use of solid wood panels, they should be cooked and dried. The use of these woods without treatment will have the potential for pests (mainly termites).

Second, some of the considerations in the woodworking process

1, nail eye treatment

The treatment of nail holes is strictly speaking of the category of painters. As the saying goes, "Three parts of a dress and seven dresses." This expression is more typical in carpentry work. Nowadays most of the renovations use reworked plates. During construction, nails and other processes are used. How to deal with these nail holes has become a prominent problem. This requires a very rigorous attitude toward the color matching of the putty, as far as possible so that the color matching color is basically the same with the surface of the wood, thereby disguising these shortcomings. The same processing also applies to the processing of tree sections and tree shrews.

2, the choice of plate

The selection of a good quality sheet is the first factor in ensuring quality. This not only requires the selection of the quality of the sheet, but also the strict choice of the suitability of the sheet. First of all, it is necessary to make the right choice for the relevant part of the plate selection, for example, the bookshelf and other load-bearing parts can use fine core plates. Second, the quality of the relevant sheet must also be controlled. For example, the quality of a fine core board varies, and the difference is very far.

3, the choice of decorative technology

Different boards require different finishes. For example, the texture of wood and veneer, then you can use varnish. With poorly textured solid wood panels or ordinary splints that do not have decorative panels, mixed oils are required. Similarly, it is inferred that if you use varnish, you should choose a solid wood or veneer with a better surface. If you use mixed oil, you only need to use ordinary plates. The practice of using veneer and mixing oil can only be a waste of money.
