After the hydropower project, it entered the mud and wood project stage. Acceptance of mud and wood is also a very important link. Netizens often think that hydropower is a hidden project that cannot be ignored. In fact, mud and wood works are also very important. In particular, if empty tiles appear after the tiles and tiles are attached, the bricks will later have quality problems, falling or cracking. Mud and wood projects have also played a very important role in the entire renovation process. They include not only the construction of "lizi" but also the construction of "face". Mud-wood projects generally include the construction of wall and floor tiles, waterproof layers, ceilings, balconies, furniture, doors and windows, skirtings, cabinets, wooden keel partition walls, etc. Each step is crucial for the entire renovation process.

1. Check the inspection product certificate, pay attention to the date of manufacture, specifications, technical conditions, company name and production license number;

2. The panel generally requires a moisture content of between 8% and 12% so that no cracking or warping will occur during use.

3. High-quality aluminum alloy doors and windows fine processing, installation stress, good sealing performance, switch freely. Pay attention to the wall thickness of aluminum alloy doors and windows; the thickness of the door and window material is not less than 1.2mm. Otherwise, the strength is not enough, it is easy to deform, forming a security risk;

4. Look at the quality of the assembly of doors and windows, mainly to see whether the appearance of clean and non-destructive, whether the welding corner clean, metal parts are not matched, with or without steel lining, etc., the most important thing is, we must check the doors and windows manufacturers have the production license issued by the Construction Committee, Never misuse the street doors and windows produced by street-shops without being greedy and cheap;

5. The thickness of the steel plate of the qualified anti-theft door frame should be more than 2mm, the weight of the door body should be more than 40kg, and the thickness of the door body is generally more than 20mm.

1. Stones with a uniform fine structure generally have a delicate texture, and coarse and unequal grain stones have poor appearance and short life.

2. Hearing sound can distinguish the merits of stone. Generally, the stone with good quality, internal denseness and no micro-cracking sounds crisp and melodious; on the contrary, the sound of cracking is coarse and dumb.

3. A small amount of ink is dropped on the back of the stone. If the ink is quickly scattered, it indicates that the internal particles of the stone are loose or there are gaps, and the quality is not good. If the ink drops do not move in place, it means that the stone texture is good.

4. Granite is generally not colored stripes, most of them only colored spots, there is a solid color.

5. 95% of the internal structure of artificial marble is natural marble powder, so the polishing degree is high. Inferior products generally have a high resin content of more than 15%, so the surface is old and dull.

Real aluminum buckle plate around the uniform, clean and shiny surface, thick paint, the international requirements of the thickness of 0.6mm paint is not easy to fall off.

Get PVC plastic buckle plate, first smell the plate, such as with a strong pungent odor, it is harmful to the body, should require the manufacturer or distribution unit to produce inspection reports.

3. Pay special attention to whether the oxygen index of PVC plastic buckle plate is qualified. It must be greater than 30 to be beneficial to fire prevention.

4. Plaster ceiling materials pay special attention to the manufacturer's trademark and prevent the purchase of counterfeit goods.

Fourth, plasterboard admission acceptance:

The gypsum board thickness of partition wall should not be less than 12mm.

In terms of appearance quality, the surface of the gypsum plaster board should be flat, and there must be no defects such as breakage, corrugation, grooves, stains, overheating, loss of material, edge leakage, and paper surface separation.

Poor ceramic tiles will have large deviations in appearance and size, and there will be significant size. Check that the edge of the tile is smooth and there are signs of damage during handling.

. The two or four pieces of tiles that have just been opened are put together and should be able to be tightly seamed and checked for obvious color differences and seams.

Tap a tile with a hard object, and the voice is clear, indicating that the tile is cooked and of good quality. If the sound is abnormal, there is a crack inside the tile.

Drop water on the back of the tile. If the water spreads quickly and leaps out, it indicates that the particles inside the tile are loose or have cracks. The quality of the tile is not good.

5. Good tiles generally have a delicate texture.

To check the manufacturer's trademark, production address, and anti-counterfeit signs, etc., don't forget to check the amount of formaldehyde released in the product test report. The lower the formaldehyde detection value, the better. Daxinban is classified into E1 and E2 grades according to its hazardous substance limits. Home decoration can only use E1 level.

To see if the surface is smooth, with or without warping, deformation, whether there is blistering, depression; core strip arrangement is uniform and neat, with or without decay, fracture, wormholes, thrift.

The products described in the test report provided by the certification company can be smelled with the nose. If the plate emits a scent of fragrant wood, the release of formaldehyde is less; if the smell is pungent, the release of formaldehyde is more.

The blockboard should pay attention to whether it is a regular manufacturer's product. Check the trademarks, production addresses, and anti-counterfeit signs of their production plants. Check the amount of formaldehyde released in the product test report. The formaldehyde detection value should be as low as possible. Blockboards are divided into E1 and E2 grades according to their hazardous substance limits. Home decoration can only be used with E1 grades. Formaldehyde levels of E2 grades are more than three times that of E1 grades. So this indicator is very important to your health.

Check whether the blockboard is smooth, warped, deformed, blisters, dents, whether the core strips are arranged evenly and neatly, whether there are decay, cracks, wormholes, and knots. The smaller the gap, the better.

Blockboard poplar, birch core is the best, dense texture, strong nail grip, not easily deformed.

Wood keel should be dry red and white pine or fir without distortion, should be based on its characteristics in accordance with the provisions of crack prevention, pest control, fire prevention, anti-corrosion treatment. The moisture content is 8% to 12%.

Summary: After reading this article, everyone has a certain understanding of the acceptance of the wood and wood project. In the process of paving bricks, there are many stresses on the paving tiles. Brick paving requires that the brick surface be flat, the seams are neat, and the corners are neat. Founder, Yinjiao straight. When paving, you should pay attention to the first paving wall tiles and then paving tiles. Before construction, it is necessary to know whether the geometry of the purchased bricks is standardized. The woodworking project is a project that completes furniture, doors, windows, and ceilings in the decoration process. Having mastered these basic knowledge, everybody can be comfortable in the decoration process.
