[China Glass Network] The annual "Golden September and Silver 10" is the "golden time" for the sales of the building materials industry, and this year's "Golden September and Silver 10" seems to be particularly attractive to businesses. Affected by the preferential policies of the property market many times, this year's decoration heat continues to heat up, and many consumers are specifically waiting for the "Golden September and Silver 10" promotion opportunity to obtain a larger discount. However, when reporters visited the market, they conducted random interviews with several consumers. They all said that they were confused in the face of various promotional designs and did not know how to choose products with quality trustworthiness. To this end, the reporter specifically interviewed Mr. Gao Jianfang, the person in charge of the Yibo door and window, which has a good reputation in the market, for the aluminum door and window products with high demand.
During the interview, Mr. Gao suggested that consumers choose from aluminum, glass, hardware accessories and sealant, and gave detailed purchasing opinions.
Aluminum: Standard thickness is 1.2mm
Mr. Yibo Doors and Windows believes that the quality of aluminum directly affects the service life of doors and windows, so consumers should pay more attention to the purchase. Mr. Gao suggested that consumers choose from the following four aspects:
1. Now there are some unscrupulous manufacturers on the market to save costs. They will use “recycled aluminum†to make aluminum. Recycling aluminum not only has weak resistance to pressure, but also harms consumers' interests, and may also cause certain harm to the human body. Therefore, consumers can choose big brands with good reputation, such as Paiya, Huangpai, Yibo. Mr. Gao introduced: “Because Yibo doors and windows are made of high quality standards and have high requirements for product quality, the famous brand Xinhe Aluminum is used exclusively, and the special aerospace titanium-magnesium alloy used by only a few manufacturers in the industry as raw materials. To make the product have good corrosion resistance and compressive strength."
Buying suggestion: In this regard, Mr. Gao pointed out that the normal normal aluminum alloy profile has a silver-white cross-section color and uniform texture. If the color is dark, it can be concluded that the recycled aluminum or scrap aluminum is forged.
2. In order to improve the wear resistance of aluminum and prolong its service life, manufacturers will apply an oxide film on the surface of aluminum and apply different colors, which is called oxidation coloring film. However, due to differences in construction techniques, these oxide films are also good or bad. The preferred oxidized colored film should have a smooth surface, a pure color and good texture, no scratches, and the cut surface is silvery and not black, which can improve the corrosion resistance of doors and windows and is durable. The surface of the poorly oxidized colored film is unnatural, uneven, scratched and discolored.
Buying suggestions: When purchasing, you can lightly scratch the surface of the sample profile to see if the oxide film on the surface can be wiped off.
3. “The thickness of aluminum in the national standard is 1.2mm, and the thickness of aluminum in the aluminum alloy doors and windows of the broken bridge is 1.4mm. The products of Yibo doors and windows have reached a high standard, and many products are higher than the national standard.†During the interview process In the reporter, the reporter learned that there are some aluminum alloy doors and windows with a thickness of only 0.6-0.8mm. The tensile strength and yield strength are much lower than the national standards. The use is very unsafe, easy to deform, and even breaks under large wind pressure. .
Shopping suggestions: Mr. Gao reminds consumers that when purchasing, they can ask the store to show the relevant aluminum cross-section, and judge whether the aluminum thickness reaches 1.2mm by the aluminum cross section. At the same time, Mr. Gao also reminded that, especially for high-rise residents, the requirements for aluminum thickness are higher. If the thickness of aluminum is not up to standard, it will be easily squashed and destroyed by storms.
Glass: three kinds of glass have their own characteristics
Mr. Yibo Doors and Windows pointed out that there are three common glass arrangements for aluminum alloy doors and windows, namely ordinary glass, tempered glass and insulating glass, and each type has its own method.
1. Ordinary glass has uniform thickness, flat upper and lower surfaces, and economic benefits;
2. The strength of tempered glass is more than three times that of ordinary glass, and it will form granules when broken, which will reduce the damage to the human body to a low level.
3. Insulating glass is usually spliced ​​together by two methods of bonding, and the two glasses are kept at a certain interval. The space is dry air, and the periphery is sealed with sealing material.
Identification method: tempered glass will have a tempered mark on the glass. The broken glass of the tempered glass has no burrs and will not cut the hand. The ordinary glass can not be touched. If it is accidentally cut, the hand will be cut. In addition, it can be stronger. Wear polarized sunglasses under light (a lot of market, dark green / blue) to observe the glass surface, especially the corners, tempered glass can see the color spot - professional saying "stress spot", ordinary glass will not.
Insulating glass should not have any smudges, inclusions and sealant splashing that hinder the see-through. The intermediate spacer layer must not have any foreign matter. The sealant or strip should be applied evenly and continuously, and firmly adhered to the surface of the glass. Air passages and air bubbles should not appear. The reporter learned that the hardness of the tempered glass used in the Yibo door and window products is several times that of the same industry. There are related tests. The Yibo door and window glass fell from a height of one meter and was not damaged.
Hardware accessories: better selection of famous brands
"Good hardware can save the trouble of maintenance, but also improve the service life of the product." Mr. Yibomen said. It is understood that Yibo doors and windows imported brand accessories, the use period is more than 20 years than the domestic general accessories, greatly reducing the after-sales trouble. In addition, Mr. Gao also gave some advice on the purchase of hardware accessories.
1. Pulley: The sliding door is divided into upper and lower sets of pulleys. Because the upper pulley is inconspicuous, many consumers often ignore its existence. Some bad merchants target the psychology of consumers, using a small wheel with a rubber ring. Pass through, so don't forget to check the upper pulley when shopping. In addition, the door should be pulled and pulled to be smooth and flexible, with a certain weight.
2. Hand, alloy, and bolt: You can move them when you buy them. If you have a bad feeling, don't buy them.
3. Sliding support: used in the casement window sash. It is better to use stainless steel material when purchasing. There are no scratches, sharp edges, burrs and other defects on the surface. When sliding the switch, there is no resistance.
4. Hinge: used to swing doors and windows. When purchasing, you can observe the hinge material, which is usually made of copper, iron-plated copper, stainless steel, aluminum alloy extrusion materials, etc., and should not use zinc alloy casting hinges.
5. Half-moon lock: Most of them are hook locks between the fan and the fan. It is preferably made of stainless steel or aluminum alloy.
Sealing material: environmentally friendly, good sealing
In addition, Mr. Yibomen window high said that the well-sealed doors and windows can prevent rainwater from entering during rainy days and keep the interior dry, and can also prevent or mitigate damage caused by mechanical vibration and impact. It indicates that doors and windows with good sealing performance should reflect the following aspects:
1. Aluminum door and window sealing strips should be made of EPDM, silicone rubber (MVQ) and thermoplastic elastomer strips. Consumers can check the product description carefully when purchasing, or ask the merchant for relevant knowledge.
2. Secondly, the door and window should be made of siliconized waterproof tops, which can prevent the hair bundle from falling down after water absorption and lose the sealing effect. The hair bundle of the top should be neat, compact and firm. After a long time of pressure Still return to normal.
In addition, industry insiders pointed out that 10% of the product problems in the industry are caused by transportation damage, and the damage of the transportation process not only causes the enterprise to lose interest, but also causes problems for consumers, such as affecting the decoration process. The industry also pointed out that this aspect is better done in the Yibo door and window, Yibo takes three layers of packaging on the product, one layer more than the peers, reflecting the rigorous production attitude and avoiding concerns for consumers.
Later, experts reminded consumers that during the "Golden September and Silver 10" period, don't be blindfolded by ultra-low prices, to buy in the formal large building materials market, pay more attention when shopping, shop around, you can buy Super The value of the product.
