Image wall bottom plate material 2 (glass)

Simple classification of glass is mainly divided into flat glass and specialty glass. In the advertising decoration industry, ordinary float white glass, tempered glass and frosted glass are commonly used. There are three main types of flat glass: top-drawn flat glass (divided into grooved/grooved), flat-drawn flat glass and float glass. Due to its uniform thickness, flat and parallel upper and lower surfaces, high labor productivity and ease of management, float glass is becoming the mainstream of glass manufacturing methods.

Wall

1. Ordinary flat glass. 1. 3-4 centimeters of glass, mm is also called centimeters in daily life. What we call 3mm glass refers to glass with a thickness of 3mm. Glass of this size is mainly used for picture frame surfaces.

⒉5-6cm glass, mainly used for small-area light-transmitting shapes such as exterior walls, doors, etc.

⒊7-9cm glass, mainly used for large-area indoor screens, etc. But it is also in a shape protected by a frame.

⒋9-10cm glass can be used for indoor large-area partitions, railings and other decoration projects.

⒌11-12cm glass can be used in floor spring glass doors and some partitions with large flow of people.

⒍Glass of 15cm or above is generally less sold on the market and often requires ordering. It is mainly used for large-area floor spring glass doors and entire glass walls.

2. Classification of special glass

1. Tempered glass. It is a kind of prestressed glass that is reprocessed from ordinary flat glass. Compared with ordinary flat glass, tempered glass has two major characteristics: the strength of the former is several times that of the latter, the tensile strength is more than 3 times that of the latter, and the impact resistance is more than 5 times. Tempered glass is not easily broken, and even if it is broken, it will break into particles without sharp angles.

⒉ Frosted glass. It is also frosted on ordinary flat glass. Generally, the thickness is mostly below 9 centimeters, with the most thickness being 5 or 6 centimeters.

⒊Sandblasted glass. The performance is basically similar to frosted glass, but the difference is that frosting is changed to sandblasting. Because the two are visually similar, many homeowners and even renovation professionals confuse them.

⒋Patterned glass. Its biggest feature is that it is light-transmitting and opaque, and it is often used in decoration areas such as bathrooms.

⒌Wired glass. It is a kind of impact-resistant flat glass made by using the rolling method to embed metal wire or metal mesh in the glass plate. When it is hit, it will only form radial cracks and will not cause injury when it falls. Therefore, it is mostly used in high-rise buildings and factories with strong vibration.

⒍Insulated glass. Gluing is often used to keep two pieces of glass at a certain distance. The gap is filled with dry air, and the surrounding area is sealed with sealing materials. It is mainly used in decoration projects with sound insulation requirements.

⒎Laminated glass. Laminated glass is generally composed of two pieces of ordinary flat glass (it can also be tempered glass) and an organic adhesive layer between the glasses. When damaged, the fragments still adhere to the adhesive layer, preventing damage to the human body from splashing fragments. It is mostly used in decoration projects with safety requirements.

⒏Bulletproof glass. It is actually a type of laminated glass, but the glass is mostly made of higher strength tempered glass, and the number of interlayers is relatively large.

⒐Heat-bent glass.

Curved glass is made by heating and softening flat glass, forming it in a mold, and then annealing it. 10. Glass bricks. The manufacturing process of glass bricks is basically the same as that of flat glass, but the difference is the molding method. There is dry air in the middle. It is mostly used in decorative projects or light-transmitting shapes with thermal insulation requirements.

⒒Cellophane. Also called glass film, it comes in a variety of colors and designs. Depending on the properties of the paper film, it has different properties. Most of them function as heat insulation, anti-infrared rays, anti-ultraviolet rays, and explosion-proof.

3. Precautions during glass construction and use

1. During transportation, be sure to fix it and add soft protective pads. It is generally transported in an upright position. Vehicles should also be driven at a steady and medium to slow speed.

⒉If the other side of the glass installation is closed, pay attention to cleaning the surface before installation. It is best to use a special glass cleaner, and wait until it is completely dry to confirm that there are no stains before installation. It is best to use clean construction gloves when installing.

⒊When installing glass, silicone sealant must be used for fixation. In the installation of windows, etc., it also needs to be used in conjunction with rubber sealing strips.

⒋After the construction is completed, pay attention to affixing anti-collision warning signs. Generally, stickers, colored electrical tape, etc. can be used to provide reminders.

Image wall base material three (large core board)

Large core board is also called block board. It is a plywood with a solid wood core, a core made of natural wood strips in the middle, and a thin veneer on both sides. Its vertical bending strength (divided by the direction of the core material) is poor, but its transverse bending strength is high. The national standard stipulates many quality standards for large core boards, including thickness dimensions, format dimensions, warpage, physical and mechanical properties, material defects, processing defects, moisture content, bonding strength, board defects, formaldehyde release limits, etc. Strict inspections of these quality indicators mostly need to be carried out in laboratories, but consumers can still make judgments through some simple and intuitive methods.

First of all, pay attention to whether the appearance is smooth and defect-free and whether the logo is complete. The surface panel of a high-quality large core board should be smooth without dead knots, gouges, glue leakage, etc. The thickness of the middle board should be uniform without overlap or seams. The splicing of the core board should be tight, especially the two ends of the large core board should not be dry or cracked. When placed upright, the corners should be straight and the diagonal deviation should not exceed 6 mm. Secondly, one side of the large core board must be a whole piece of wood, and only one patchwork seam is allowed on the other side. Touch the surface of the blockboard with your hands. A high-quality blockboard should feel dry, flat and smooth.

Third, check whether the filling material is dense. Saw a corner and check the small wooden strips spliced ??inside. The gap should not exceed 5 mm. Do not use wood with bark, holes or dead knots. At the same time, it is also necessary to check whether there is glue or putty on the surrounding area. This phenomenon is usually to make up for internal cracks or holes. Generally, in large core boards with good quality, the small wooden strips are connected by zigzag tenons.

There is a simple way to identify the internal quality of the large core board: observe the large core board under a bright light. If it is white, it means that the wood strips are not spliced ??tightly enough; listen for the sound when you pick it up. If there is a squeaking sound, it means that the glue strength is not enough. Good; when it feels dry, lift one end of the large core board and weigh it. A high-quality blockboard should have a sense of integrity and thickness; tap the surface of the board with a sharp-nosed instrument and listen to see if there is a big difference in the sound. If the sound changes, it means there is a cavity inside the board.

Fourth, see if there is an odor. If the large core board emits a fragrant wood smell, it means less formaldehyde is released; if the smell is pungent, it means more formaldehyde is released, so it is best not to buy it. In addition, the greater the weight of the large core board, the more it indicates that the board uses miscellaneous wood. This kind of large core board made of miscellaneous wood cannot be driven in with nails, so it cannot be used.

Generally, the thickness of commonly used large core boards is 16.5-18 mm thick, and the thickness of the skin is 0.3-0.5 mm. The better brands include Ruijia, Baili, Dehejia, Kangcai, Pule, Montblanc et al. Large core boards can be divided into high-quality products, first-class products and qualified products according to the quality of the material and the texture of the surface material.

There are also companies that label the board grades as Grade A, Double A and Triple A, but this is just corporate behavior. There is no Triple A grade in the national standards. This kind of labeling is no longer allowed in the market. During use, the large core board can only be opened along one long side and cannot be sawed horizontally. In addition, the large core board cannot be used as a panel. A layer of plywood must be pasted on the outside as a panel, otherwise problems such as paint bubbling may occur. Image wall base material four (fireproof board)

The scientific name of fireproof board is refractory board, also known as high-pressure decorative board. The more professional name is high-pressure melamine resin laminate. It is an interior decorative surface material produced by impregnating kraft paper in resin and undergoing high temperature and high pressure treatment. It has the characteristics of wear resistance, heat resistance, impact resistance, acid and alkali resistance, smoke resistance, fire resistance, antibacterial, antifungal and antistatic properties. The specifications of fireproof boards are generally 2135mm×915mm, 2440mm×915mm, 2440mm×1220mm, and the thickness is 0.6-1.2mm.

Walls

Imitation wood grain, imitation stone, and newly emerged metal finishes, fireproof board is a master of change, and it seems that there is no effect that it cannot imitate. Today, with the rising awareness of environmental protection, wood and stone are listed as being used with caution. The good-faith imitation of the two by fireproof boards satisfies people's visual experience. Its changeable mechanism also caters to people's psychology of pursuing novelty and novelty. Therefore, , it is not surprising that it appears frequently in the building materials city. Metal-effect fireproof panels provide designers with the possibility to experiment with their creativity. Background walls, parts of the entire cabinet, etc., metal fireproof panels of any shape can add color to the interior. If you choose real metal plates (aluminum plates, stainless steel plates, etc.), the construction is complicated and the price is high, and fireproof boards are a cheap substitute. No matter what changes are made, the quality of the fireproof board is the most important. Inferior fireproof boards generally have the following characteristics: uneven color, easy to crack and burst, and simple colors. In addition, its heat resistance, acid and alkali resistance, and wear resistance are also relatively poor.

Image wall base material five (aluminum-plastic panel)

Aluminum-plastic panel is also called aluminum-plastic composite panel. It was successfully developed by Germany in the 1960s and entered the market in the late 1980s and early 1990s. Chinese mainland. The aluminum-plastic panel industry has achieved extraordinary development in mainland China in just 10 years. In just a few years, China has become the country with the largest use and export volume in the world. The current annual output is approximately more than 500 million square meters, and the output value is nearly 400 million. billion yuan.

Aluminum-plastic panels are currently widely used in indoor and outdoor decoration. Due to their low price, various colors, convenient construction, excellent processing performance, excellent fire resistance, noble quality, and convenient transportation, they have become a Dry hanging stone, glass curtain wall, ceramic tile, cement alternative materials are widely used in curtain wall decoration of high-rise buildings, building pillars, old wall renovation, store decoration, advertising signs, ceiling partitions, etc. Aluminum-plastic composite panels are composed of multiple layers of materials. The upper and lower layers are high-purity aluminum alloy panels, and the middle is a non-toxic low-density polyethylene (PE) core panel. A protective film is also pasted on the front. For outdoor use, the front side of the aluminum-plastic panel is coated with fluorocarbon resin (PVDF) coating, and for indoor use, the front side can be coated with non-fluorocarbon resin coating.

The national standard for "Aluminum-Plastic Composite Panels" implemented in 1999 stipulates that aluminum-plastic panels are divided into two types: interior hanging and exterior wall hanging. The interior hanging is composed of two layers of 0.21 mm aluminum plates and PVC. The thickness of the plastic composite panel should reach 4 mm, consisting of two layers of 0.5 mm aluminum plate and 3 mm PVC material. The paint surface should use fluorocarbon paint that can resist aging for 20 years. The adhesive material should be about 30,000 yuan per ton. Polymer materials.

Features of aluminum-plastic panels: Aluminum-plastic panels are good materials that are easy to process and form. It has strong bending, good flatness, stable quality, high flexural resistance, high sound insulation and fire resistance, light and bright, high temperature resistance, weather resistance, decay resistance, friction resistance, and not easy to stain. Aluminum-plastic panels can be cut, trimmed, slotted, band sawed, drilled, countersunk processed, and can also be cold-bent, cold-folded, cold-rolled, riveted, screwed or glued, etc.

The thickness of aluminum-plastic panels can be divided into three specifications: 1mm, 3mm and 4mm. Aluminum-plastic panels with different specifications have different prices, which are mainly determined by the thickness of the aluminum film and the texture of the intermediate material. At present, the price of 3mm and 4mm thick aluminum-plastic panels, which are more common on the market, is generally 200-300 yuan/sheet, and the price of 1mm-thick aluminum-plastic panels is only 90 yuan/sheet. Nowadays, for outdoor decoration, such as building curtain walls, billboards, etc., aluminum-plastic panels with a specification of 4mm are mostly used. For indoor decoration, for ceilings in kitchens and bathrooms or as decorations for theme walls in living rooms, 3mm thickness can be used.

Cultural stones are divided into two types: natural cultural stones and artificial cultural stones. This type of stone itself does not have any cultural meaning, but because it has the characteristics of natural texture and color and maintains the style of natural original stone, it can fully display the connotation and artistry of stone texture, catering to people's cultural concept of advocating nature and returning to nature. This kind of stone has been given the reputation of cultural stone.

Natural cultural stone is processed from natural stones such as slate, sandstone, quartz stone, etc. This type of stone is formed in nature through hundreds of millions of years of crustal movement and has a characteristic layered schistosity structure. , not only is it easy to split along the schistosity, but the surface of the split stone is rich in texture and can be made into sheets for inlaying walls. The structure of this type of stone is dense, and its layered schistosity determines that its hardness and wear resistance are between granite and marble. It is also hard, bright in color, rich in texture, and in different styles. It is pressure-resistant, wear-resistant, and fire-resistant. , cold resistance, corrosion resistance, low water absorption, high acid resistance, and not easy to weather.

Artificial cultural stone is made of natural cultural stone as a matrix, plus calcium silicate, gypsum and other inorganic materials. Because it imitates every subtle trace of natural cultural stone, it also has a realistic and natural appearance. Look and feel. Artificial cultural stone is lighter than natural cultural stone, easy to shape and easy to install. It is also non-toxic, flame retardant and rich in color. Cultural stone is widely used in the fields of public buildings, villa gardens and interior decoration. It has become the new favorite among decorative materials due to the ingenuity of designers. When using cultural stones, factors such as the area and light of the hall should be considered. Moreover, the use of cultural stones should not be excessive or excessive, otherwise it will be counterproductive. For large living rooms, larger stone slabs can be used, or they can be inlaid in irregular splicing patterns. When decorating the walls of a small living room, it is best to use small-sized, light-colored, flat cultural stones, which can visually widen the living room. If it is used to decorate TV background walls, image walls, wall scenery, etc., since most of them need to be equipped with spotlights, you can choose vicissitudes of vicissitudes, tiger skin stones, etc. with darker colors. Cobblestones and other rough non-slip stones can be used for the walls and floors of the balcony.

Image wall base material seven (acrylic)

Acrylic (ACRYLICS), also known as acrylic, chemical name methyl methacrylate (PMMA), is the most popular plastic. It is the best and easiest to process thermoplastic material. Its various finished product specifications are widely used in colored light covers, car and ship door and window glass, door and window covers, windshields, daily necessities, decoration, advertising materials, handicrafts, crystal furniture, and shower equipment. , kitchen utensils, etc.

The advantages of acrylic sheets are high transmittance, low turbidity, lightness and strength, good processing performance, rich colors, excellent electrical insulation, excellent weather resistance, and can withstand High temperature, ultraviolet light, strong sunlight, resistance to solvents and common chemicals, high recyclability; the disadvantage of acrylic panels is poor impact resistance, but improved acrylic panels can meet the resistance requirements of most occasions meet performance requirements.

In prosperous commercial centers in Europe, America and Japan, acrylic advertising boards and light box signs are used to advertise corporate image and product promotions, which can be described as dazzling and colorful. Among many raw materials, the application rate of acrylic is as high as 70%. Due to the various good characteristics of acrylic, acrylic materials are increasingly favored by people in the advertising industry.
