Difficulties in decoration, imperfections in the construction of many poor quality building materials
Why do we always face a variety of problems when we are decorating? Not all kinds of text traps were encountered during the signing of the contract. They were constantly deceived by unscrupulous construction teams during the renovation process. The purchase of building materials is even more frightening, and it is feared that if you spend a lot of money, you will buy defective goods. However, the construction of the entire home, all kinds of basic, and major materials are indispensable. Faced with so many poor quality building materials, the decoration people can not help but shout in their hearts: When will this type of deception come to an end? The quality problems brought by various inferior building materials 1. The metallic wallpaper has a tangy smell. “Why, when I buy wallpapers, I will feel a pungent smell when I open the wallpaper. I think it has problems, but the seller says that As long as it is plastered on a wall, it will be all right. Is this metal wallpaper safe? If it is really on the wall, then the volatile gases will be sucked in by us. It is definitely harmful to our health, what should we do? ?" Last week, Ms. Li sent such a help post on the forum. After seeing the problem, Xiao Bian interviewed some salesmen in the wallpaper industry. They said that the so-called metallic wallpaper is metal, gold, silver, copper, tin, aluminum, etc. Wallpaper surface. The commonly purchased metal wallpaper is called "gold foil." The price difference between the entire finished wallpaper market is relatively large, ranging from 20 yuan per square meter to over one thousand yuan per square meter. In fact, what the sales staff said was made of gold, silver, copper and other heavy metal wallpapers were all made of paper. The electrolytic aluminum was made into a thin film by a special method, and the electrolytic aluminum was stuck to the paper with a binder. . As for Xiao Bian’s question about why the metal wallpapers would make him want to vomit, the sales staff said that electrolytic aluminum itself is odorless, and the odor is emitted because the base paper coating is a poor quality ink solvent. 2, waterproof material is actually not waterproof Whenever you enter the rainy season, there are always many owners feeling so easily why their own homes have become "a vast ocean," and before the renovation are obviously made of waterproof. Compared to wires, pipes, floors, and other building materials, the quality of waterproof materials is considered by some people as "small problems." However, the fact is that the waterproofing of the roof is an important project of the house construction. The leakage of the roof will directly affect the function and life of the building. Recently, the incidents of “building†and “crushing and brittle†which were exposed by the media have all been related to the waterproof quality of buildings. Although there are quite a few national standards concerning waterproof materials, the actual implementation of the standards is not in place. Some inferior products have changed a new name, and they enter the market in a grandiose manner to squeeze qualified products from regular manufacturers at low prices. Construction workers do not understand the process, blind construction is also an important factor affecting the waterproof effect. When heavy rain or heavy rain comes, joints are particularly vulnerable to water seepage, and the treatment of local leaks is often more troublesome than new construction, so leaks have become difficult to cure the "diarrhea." 3, the sheet of formaldehyde is exceedingly excessive Ms. Ye's new home has been renovated for 5 months, but Ms. Ye has not been able to move into her new home. "I can't stand it for 10 minutes each time, my nose is itchy and my eyes are in tears, and I feel bad for me." Ms. Ye said that the bad smell came from the three big cupboards built in the room. “When the sheet was just pulled, I smelled a strange smell. I was thinking about letting it go for a while. Who knows it is still so heavy.†Later, the relevant testing agency was invited to test and said that the amount of formaldehyde in the air in the home exceeded the standard. Six times, and the inspectors say that the formaldehyde in these large cabinets is estimated to be volatile in two to three years. In the current market, various types of decorative auxiliary equipment, such as particleboard, medium density fiberboard, plywood, new furniture, wall or floor, use adhesives based on formaldehyde. If the concentration of formaldehyde in the air is too high, it will have an adverse effect on the human body. 4, tiles into "mud dolls" Mr. Huang is watching TV in the living room one day, suddenly heard from the kitchen, "dangling" sound. He quickly ran into the kitchen and saw that the white tiles on the windowsill fell to the ground and fell into several large pieces. "How did the tiles fall off suddenly?" Mr. Huang was not assured. He checked other tiles and found that many of the tiles had cracked and hollowed out. "If you don't deal with it, you may have to drop a few pieces." In people's minds, tiles should be durable products. It should be no problem to use them for 10 years. However, in fact, some tiles became muddy dolls soon after they were laid, and some cracked and hollowed out. This includes both the quality of the tiles themselves and the improper methods used to tile them. If the tile hardness is not enough, in the course of use, if the load is too high, it will be easy to crack; if the tile is not flat, the corners will be upturned, it will cause the tiles to become bent; if the tile's water absorption is high, the surface will easily yellow, appear black point. In the process of laying, if you do not reserve a suitable gap, it will cause the tiles to be cracked, cracked, or fall off; failure of the adhesive will cause problems such as hollowing and falling off after the tiles are laid; Tile cracking, will appear horizontal, vertical or oblique regular cracks. Rights protection is imminent The face of the renovation of the decoration market building materials, the consumer is the first to do is to go to the general building materials supermarkets and regular home stores to buy, but also when buying a brand business is the first choice, after the purchase must remember to ask for after-sales Single rights protection items, in case of need. The quality management and supervision of basic building materials, such as plates and waterproof materials, requires the joint efforts of manufacturers, construction units, and acceptance organizations. As the owner, it is best to be able to directly participate in or entrust the supervision department to participate in the selection and purchase of materials and the supervision and inspection of construction site materials, and refuse to use fake and shoddy products. For ordinary consumers who are not familiar with sheet metal expertise, the first thing to look for when purchasing a sheet is the grade of the product labeling. E0 sheet is the first choice, followed by the E1 sheet, and again the E2 sheet. In addition to looking at inspection reports and keeping good invoices, you can also see a small piece of board left as evidence, preferably signed by both parties. On the purchase of ceramic tiles, the problem can usually be seen from the appearance. If there are black spots or pinholes, this is due to the failure of the ceramic tile in the calcination process. In addition, scratches, cracks, etc. may appear on the surface of tiles, which may be caused by collisions during transportation. Therefore, in the decoration, the purchase link should be avoided as much as possible to avoid the selection of quality and cheap items, for the future decoration and peace of mind, but if you really encounter quality problems, you first find the building materials city or distribution of purchased materials Businessmen, it is recommended that building materials should be purchased in a building materials city that has a prior payment service. Problems can be solved as soon as possible.
