1, recognize the brand of aluminum plate: aluminum plates produced by large enterprises all have a protective film of their own brand on the surface (no brand is just a transparent white protective film, so it can be concluded that it is not a brand, or even an inferior product).
2. Identification of brand steel seal: It is necessary to avoid that the ceiling and keel are from different manufacturers, which will affect the installation accuracy. Various panels with different structures produced by large enterprises have their own supporting keels, and the keel, pendant, square aluminum plate, bottom or edge of each home improvement panel will be branded, so the machine pressure cannot be erased. (There is no imprint, it is likely that the seller went to a small processing factory to paste the brand with inferior materials, because this can reduce the cost. ) Without brand protective film and brand imprint, it can be determined that it is a product of a small processing factory. Because in the past two years, many small processing plants have sprung up all over the country, preparing some materials made of recycled aluminum containing harmful substances such as chromium, lead and mercury, and processing them on the spot near the decoration market. It is convenient for people with famous brand sellers to transfer goods, or people without brands to order.
3. Look at the material of aluminum plate: it depends on the quality of aluminum plate, not that the thicker the aluminum plate, the better. At present, most of the 0.8-thick aluminum plates for home decoration in the market are inferior products produced by small processing plants. Inferior aluminum gusset plate often cheats on aluminum substrate and aluminum gusset plate coating, usually by reducing the thickness of aluminum substrate and using a thick coating on aluminum substrate. Even some aluminum gusset plates on the market have only 0.43mm aluminum substrate, but the coating is 0.3 mm (when facing consumers, it is said that this is 0.8 thick. If the base material of aluminum gusset plate is too thin and the coating film is too thick, the performance of aluminum gusset plate will also decline. Because this kind of aluminum gusset plate has low cost and its thickness can cater to the psychology of unsuspecting consumers, it is very deceptive, and many consumers are easily fooled by it. In fact, considering the installation span requirements of home improvement products, under the premise of using high-quality aluminum, experts suggest that the thickness of aluminum gusset plate used in home improvement is 0.6-0.7, which is enough, because this thickness of aluminum gusset plate has the best cost performance and can fully meet the bearing strength. If the thickness is thick, it will not only waste resources, but also increase the unnecessary economic burden of consumers. Good quality aluminum plate has certain hardness, elasticity and toughness, and can be restored to its original state to a certain extent after bending, and will not be aged and deformed after long-term use. When you tap the aluminum gusset plate with your finger, the metal sound of the aluminum gusset plate with good material is obvious and crisp, and the metal sound of the aluminum gusset plate with poor material is dull and not obvious.
4. Plate primer comparison: Primer can protect the water vapor generated by aluminum gusset plate in normal life in kitchen or bathroom from penetrating to the bottom of gusset plate, and make the bottom of gusset plate of ceiling contact with water and air for a long time. After a long time, the aluminum gusset plate will rust and mold from the bottom until it loses its function. The primer of high-quality aluminum gusset plate should be evenly sprayed on the bottom of the plate, and the specific uniformity should be such that when the bottom of the plate is carefully observed with eyes, silver-gray dots will not appear (the aluminum plate itself is silver-gray of aluminum itself). Especially the "ventilation module", after all, the air circulation there is relatively fast, which is easy to cause oxidation problems and affect the service life.
5. Look at the color of the laminating board: mainly look at the process of laminating the ceiling. The brighter the surface, the better. Generally, the film with good quality has fine and smooth surface and good reflectivity, and the surface will not wrinkle and change color after long-term use. (Good film thickness is only 0. 10mm-0. 15mm).
6. Look at the keel: The quality of the keel is a problem that many consumers ignore. The material of keel is generally divided into aluminum, iron and fingerprint-free steel. Aluminum keel will not rust, but because of the high cost, the sales volume is very small. Iron keels rust easily. Although the keel section is hidden behind the ceiling and generally invisible, the rust scattered on the ceiling is not good for the ceiling, and it will also affect the stability of the ceiling over time. Compared with iron keel, fingerprint-free steel keel is not so easy to rust, and it is the most commonly used and sold type of home improvement equipment at present.
7. It is very important to care about the quality of services and accessories and understand the charging standards, because some business households in the market have received money, and the subsequent service and quality commitments are not lost.
In addition, consumers can also identify by the following simplest methods:
① Appearance inspection: the surface gloss of the base material is good, and there are no defects such as cracks, corrosion, perforation, folding, creases, serious scratches, oil stains, sticky wounds, imprints, pine-like patterns, metallic and nonmetallic pressed objects, etc. Aluminum ceiling profiles are free from black, gray and green impurities.
② Handle: The surface of aluminum ceiling is fine and smooth.
(3) Good elasticity. Hold it hard, and its natural tension will restore the panel to its original natural state. When the substrate is cold-bent at 90 degrees, there will be no bending crack, and its bending radius will not exceed half of the thickness of the substrate. Looking at the ceiling market of home decoration, the ceiling made of single traditional plastic and plastic-steel variegated materials can no longer meet the market demand and the pursuit of healthy, environmentally friendly and high-grade life by consumers. Although the traditional plastic-based ceiling is cheaper, its disadvantages are obvious. For example, it is troublesome to install, not environmentally friendly, not beautiful enough (holes need to be drilled to install electrical appliances), not safe enough (not fireproof and waterproof), short service life, and will change color and deform after a long time. Nowadays, the emerging metal integrated ceiling has solved this series of problems and has the following advantages compared with the traditional ceiling:
1, fashion style: integrated ceiling is to achieve unity and harmony through the overall combination of various functions you need (including lighting, ventilation, heating, etc.). Compared with the traditional ceiling, it has rich colors and high surface flatness, showing a more modern, fashionable and luxurious style.
2. Get home safely: The integrated ceiling has been carefully designed and professionally installed, and its wiring layout, ventilation and heating effects have also been strictly designed and tested. Everything is people-oriented. In contrast, the traditional ceiling is too casual and unsafe.
3. Green energy saving: the integrated pendant has independent functions, and the position and quantity of warm lamps can be installed according to actual needs. Traditional hanging objects are heated by Yuba, which has great limitations and the heating position is too concentrated. The integrated ceiling overcomes these shortcomings, and the heating range is large and uniform. Three warm lamps can achieve the effect of four warm lamps in Yuba, which is green and energy-saving.
4. Free choice and collocation: the functional components of the integrated ceiling are absolutely independent. You can choose the required ceiling board according to the size of the kitchen and bathroom, the color of the tiles and your own preferences. In addition, there are many options for heating components, ventilation components and lighting components, which can be freely matched.
5. High comprehensive cost performance: the unit price of the integrated ceiling is higher than that of the traditional ceiling, but you should know that it is made of high-quality aluminum (aluminum-magnesium alloy), and most of the traditional ceilings are plastic. The life of integrated ceiling can reach 50 years, while the life of traditional ceiling is only about 10 years.
