Hardware accessories mainly depends on the material and workmanship It is understood that the general hardware accessories are mainly copper, alloy, stainless steel and iron four components, their prices are also very different. At present, the most used home decoration is stainless steel hardware, but there are disadvantages such as impure stainless steel material and water stains. At present, many families use aluminum alloy accessories. According to industry sources, the aluminum materials claimed by some businesses in the market are only alloy materials containing aluminum components, aluminum alloy materials including silicon, magnesium and other components, different aluminum alloy materials and surface film thickness and surface treatment process. There is a big relationship, these factors often affect the price and quality of materials. The CEO of a company introduced that the surface treatment process mainly includes oxidation, sanding, electroplating, wood grain and baking paint, and the price of the products also varies greatly. Take the sliding door frame as an example, the market price of the product using oxidation scrub technology is per square. About 180 yuan, while the electroplating process products reached 260 yuan per square meter, the price difference of nearly 45%.

Common aluminum alloy materials in the market are mainly aluminum-magnesium alloy and aluminum oxide. The price difference between the two is also nearly one-third. Since the surface of aluminum oxide and aluminum-magnesium alloy material looks the same, it is more difficult for consumers to distinguish them. Large, but consumers can judge from the feel, water stains and other aspects. Experts said that the aluminum-magnesium alloy material is relatively heavy, the surface is relatively smooth, not easy to appear water marks, toughness; and alumina material is rough surface, easy to black and water marks. At the same time, if there are slight scratches on the surface of both, aluminum-magnesium alloy materials are easily erased, and alumina is difficult to remove. In addition, the door handle will also have a big difference in price due to the difference in hole pitch and type.

Beware of stainless steel becoming "stainless iron"

Many businesses in the promotion of stainless steel accessories will be replaced with stainless iron, that is, stainless steel materials blended with a lot of iron components, the price difference of nearly twice. Taking a towel rack as an example, the average price of stainless steel is 200 yuan each, and the price of non-ferrous iron is only 70 yuan each. The surface is basically the same, but the surface of the stainless steel material is brighter and the stainless steel is used for a time. Long, the surface is prone to black rust.

In addition, there are some counterfeit products using inferior aluminum alloy as raw materials, the surface is coated with a layer of metal light, posing as high-grade stainless steel, judging the two materials, consumers can beat the surface, if issued a crisp sound is mostly stainless steel, if it is Dreary sounds are likely to be "clothing" aluminum alloy.

Bathroom is best to use silver mirror According to reports, the current home improvement generally used mirrors are divided into general mirror and silver mirror two, the price difference between the two is about 30%, the market price of silver mirrors average 80 yuan per square meter to 90 yuan , And the general mirror is only 50 yuan per square meter, and the quality is also very different. The difference in material is the main factor that causes the price difference between the two. The silver mirror is coated on the back with a layer of mercury and then painted; while the back of the mirror is coated with a layer of aluminum and then painted, and the effect of water and fog drops a lot. After the water, the mirror frame is easy to reddish, and the paint is easy to fall off. In addition, baking, printing, tempering and other processing technology also affects the price of the mirror.

The main factor affecting the overall quality of the waterproof coating main agent affects the waterproof engineering quality is the biggest factor is the waterproof coating. According to reports, waterproof coatings are mainly divided into two types: waterborne and polyurethane. At present, home improvement uses more water-based waterproof coatings. There are four main categories: water repellent directly added to cement, waterproof coating without main agent, and main agent. Rigid waterproof coating, plus the main agent flexible coating. The first kind of waterproof agent added to the cement will not achieve waterproof effect at all, and it is mostly found in civil engineering. At present, the most commonly used are rigid and flexible coatings, and their difference lies in the different proportions of the main agent and the powder. The ratio of the main agent to the powder of the rigid coating is 1:8, and the flexibility ratio is 1:2. The larger the dose, the better the waterproof effect.
