1, original glass:
Glass is an amorphous inorganic material with quartz sand, soda ash, feldspar and limestone as main raw materials, which is melted, molded and solidified by cooling. It has transparency that ordinary materials can't achieve, and has excellent mechanical and thermal properties. And with the development of modern architecture, it is also developing in the direction of multi-function. Deep-processed glass products can control light, adjust temperature, prevent noise and improve the decorative nature of architectural art. Glass is no longer just a lighting material, but also a structural material and decorative material of modern buildings.
The quality of the original film is affected by the refining equipment, technology and process of the original glass film factory, and the quality is not the same. Bubbles, pinholes, black spots, white spots and fog (poor permeability) often appear in poor quality original films.
The first good manufacturers of architectural glass in China were Shenzhen Southern Glass Group and Shanghai Yaopi Company (Shanghai Hua Yao pilkington Group).
The glass used in Deng Yu products is: Shanghai Yaopi Company.
2. Classification and difference of ordinary glass: A. Ordinary glass: that is, ordinary glass that has not been bent or tempered. Its impact resistance is poor and its fracture state is random. If it is used in the shower room, once the glass breaks, it will do great harm to the human body, even fatal.
B. Hot bending glass: bending glass made by heating and softening flat glass in a mold and then annealing. The strength of hot-bent glass is slightly higher than that of ordinary glass, but the broken state of glass is also arbitrary, which is harmful to human body, but the advantage is that it can bend glass in an arc that toughened glass can't.
C. Semi-tempered glass: The glass that does not reach the temperature of tempered glass after tempering is called semi-tempered glass. The main feature of semi-tempered glass is that the particle size and shape are irregular after crushing, which is harmful to human body.
D. Tempered glass: A compressive stress layer is formed on the glass surface by physical or chemical methods, and the glass itself has high compressive strength and will not cause damage. When the glass is subjected to external force, this pressure layer can offset part of the tensile stress and prevent the glass from breaking. Although the inside of tempered glass is in a state of great tensile stress, there are no defects in the glass, which will not cause damage, so as to improve the strength of glass. Toughened glass is much more elastic than ordinary glass. A piece of tempered glass with 1 200 mm× 350 mm× 6 mm can have a bending deflection of 100mm after being stressed. When the external force is removed, it can still be restored to its original state, while the bending deformation of ordinary glass can only be a few millimeters.
The quality of tempered glass is affected by the differences in equipment, technology, technology and management between the original glass and the glass deep processing plant. At present, Deng Yu Company uses the original glass of Shanghai Yaopi Company, and Foshan Jinyaohua Company, the largest and most professional company in Guangdong, carries out deep processing of glass (introduction, edging, drilling, sanding/screen printing and tempering).
The temperature of 6㎜ tempered glass is about 695℃, which will change according to the thickness of the glass. The spontaneous explosion rate is high at high temperature, and the particles are uneven or even large and sharp at low temperature. The broken grains of tempered glass should be ≥40 grains /50×50㎜. The broken grains of tempered glass of Deng Yu Company are between 60 and 80 grains per 50× 50 ㎜. The glass has high transparency, uniform tempering and high safety factor. This is a kind of automobile tempered glass which meets the national 3C and European BS6206 standards, and it is also the best quality tempered glass in China.
In the aspect of glass inspection: Deng Yu uses the original strong light inspection table and glass impact table to test and control the quality of safety tempered glass in Deng Yu.
Low-grade shower rooms mainly use cheap tempered glass or semi-tempered glass, even ordinary ones. The main disadvantages are: using low-quality original glass: the glass has low purity, poor permeability, many bubbles and many impurities, which will also affect the tempering quality of glass.
In addition, the cheap tempered glass mainly exists in the poor equipment, technology, technology and management of the glass deep processing factory (glass factory), with low production cost but poor quality.
Poor quality tempered glass not only affects the beauty of products, but also has a low safety factor, such as uneven tempering. Once broken, the particles are large and sharp, which is extremely harmful to human body. Semi-tempered or even non-tempered glass is more dangerous.
3, aluminum alloy (aluminum profile):
Aluminum is a metal element extracted from aluminum ore. The country with the best aluminum ore in the world is Canadian, followed by China and then Australian. There are many aluminum mine bases in China, such as Guizhou, Shanxi and Gansu, among which the best aluminum mine belongs to Guizhou. Because there are many shower room enterprises in Foshan, aluminum profiles require not only good toughness, but also good hardness. Therefore, the aluminum ingot in Zhongshan is a combination of Guizhou aluminum ingot and Australian aluminum ingot-Foshan aluminum for short. Foshan aluminum is well-known in the industry, because it is mainly made of high-purity aluminum ingots and other metal elements, so the quality is good and the price is high.
Foshan aluminum is made of high-quality aluminum ingots containing about 5% zinc, iodine, sodium, magnesium, titanium and other elements at a high temperature of 2000℃, and then the aluminum alloy solution is cast into a 500㎜ long aluminum bar with a mold, softened at a temperature of 1000℃, and extruded into the required aluminum profile through a mold, which is called aluminum profile. The factory in Zhongshan produces a large number of building profiles, mainly using low-priced aluminum ingots and recycled waste aluminum materials for processing. This aluminum profile is not hard enough, with many impurities, brittle, uneven density, large color difference after oxidation, and many defects such as sand holes, pinholes and mottled surface. But the advantage is cheap.
Deng Yu shower room is made of Foshan aluminum, which is the best and most suitable shower room in Foshan. The hardness of aluminum profile is about 13 ~ 14 degrees, and the wall thickness of aluminum profile is1.5 ~ 3.0mm, even reaching 4 ~ 6mm. Its hardness and toughness are moderate but not brittle, and many important indexes such as tensile strength, yield strength and elongation are superior to those in China.
Methods of comparing aluminum materials:
A, inferior aluminum profiles have color difference, grain, sand holes, etc. On most surfaces after oxidation;
B, the high-quality aluminum profile has good hardness, less impurities and bright section;
C, low-grade shower room aluminum profile cut uneven burr, hard clip aluminum profile soft;
D, pull up the whole body to prove its bearing capacity.
In terms of aluminum profile structure, all tracks in Deng Yu adopt original "V" shape or "I" shape design, the matching precision between pulleys and aluminum is high, and the door is smooth and smooth during opening and closing. The upper rail is equipped with double pulleys or three pulleys to prevent derailment, and the lower rail adopts beads or hooks to ensure that the door will not derail under abnormal use. Other manufacturers are all U-shaped tracks like the upper and lower tracks, the doors are easy to derail, the gap is large, and the wall connecting part has no left-right adjustment function, so it is impossible to correct the wall construction error, and there are many burrs, unevenness and rough overall feeling.
4. Pulley:
Pulley is the most important part of push-pull shower room. Only pulleys with reasonable structure and excellent material can guarantee the service life of products. Deng Yu shower room pays attention to the perfect combination of pulley and track from beginning to end. All the stressed pulleys in Deng Yu shower room are encapsulated by imported stainless steel bearings, and the pulleys have passed 6,543,800 times of continuous destructive anti-fatigue push-pull tests. In addition, the exclusive use of V-track design, pulley is not easy to wear, no vacancy, small gap, no shaking. The pulley is also designed with a safety device, so that the pulley will not derail in the case of barbaric use, which is absolutely safe. (In addition, briefly introduce the differences of various series pulleys in Deng Yu. )
The pulley of low-grade shower room is not innovative in research and development and blindly copied. The pulleys commonly used in the market can be roughly divided into: A. Carbon steel pulleys-easy to rust, fragile and corrosive. Generally, the outside of a bearing is black and coated with white glue. Please pay attention to identification; B, zinc alloy pulley-fragile and easy to wear, covered with black or blue soft rubber, not resistant to friction, easy to fall off, but the advantage is that the sound is small when pushing and pulling; C rubber coating design of steel shaft. This kind of pulley is common and easy to identify. The middle part is brass, and there are steel balls between the copper shaft and the rubber coating. The pulley has a large gap, and dust can easily penetrate. Finally, the steel balls get stuck or the friction increases, resulting in the rubber coating falling off and the pulley being damaged.
5, hardware accessories:
Deng Yu shower room frameless series mainly adopts 62 # copper fittings and 304 stainless steel fittings.
62 copper is a kind of copper alloy, and 62 is a label. The higher the label, the higher the copper content and the higher the cost. For example, the big bent head of the shower head must be made of 62 copper or higher, otherwise the toughness is not easy to crack or break. Another factor affecting the quality of copper fittings is electroplating quality. All electroplated parts (including plastic parts) in Deng Yu shower room must be plated with seven layers, the first layer is plated with alkaline copper, the second layer is plated with glue copper (using the best glue copper imported from South Africa in the world), and the third layer is plated with acid copper (the purpose of plating three layers of copper with different properties is to clean, trim and fill tiny pinholes on the surface of copper parts for many times; ), the fourth layer is plated with semi-gloss nickel, the fifth layer is plated with full-gloss nickel, and the sixth layer is plated with nickel. (Because the nickel surface is honeycomb-shaped, it needs to be plated with two layers of nickel with different properties to correct the pits and avoid quality problems such as black spots and pinholes on the product surface. The nickel is 200,000 yuan/ton, and the cost is high); The seventh layer is chrome-plated to prevent corrosion and keep bright, improving hardness and wear resistance; The surface is also treated with electric paint, which is more wear-resistant and not easy to scratch. The electroplated parts in Deng Yu have passed the 24-hour acid salt spray test (exceeding the national enterprise standard), and there will be no bad phenomena such as black spots, blisters and delamination on the surface.
In the research and development of products, Deng Yu Company continuously improves the quality requirements of products, and adopts more upscale and luxurious 304 stainless steel fittings in frameless series (304 is the label of stainless steel, common 202 stainless steel, 304 stainless steel and 3 16 stainless steel, the higher the label, the higher the nickel content, and the higher the rust resistance and corrosion resistance. ), such as D5, D 7 and D 8 series, are all made by precision casting, careful grinding and precision polishing, and their corrosiveness, hardness and grade are higher than those of copper and other materials. But the disadvantages of stainless steel are high hardness, difficult processing and high cost.
Low-grade shower room factories mostly use copper alloy fittings with lower label in frameless, but the electroplating quality can't meet the requirements of national standard at all, which is far from that of Deng Yu. In addition, many manufacturers use zinc alloy, aluminum alloy or plastic parts in material selection (for example, Fu Rui's shell series are all made of zinc alloy, Carrier's frameless aluminum alloy series and aluminum alloy fittings and plastic parts for frameless sliding doors). Zinc alloy has poor weather resistance. Generally, the service life of zinc alloy handles on doors and windows will break in about two or three years, while the grades of aluminum alloys and plastics are low.
In the design structure of accessories, all the wall fixing clips and glass clips in Deng Yu can be adjusted back and forth, which can correct the mistakes in wall construction. The lower part and side of the glass are equipped with waterproof rubber strips, which has good waterproof effect, protects the glass and prolongs the service life of the product. The low-grade products and shower rooms made by the decoration company are purely patchwork, the product structure is not rigorous, Jerry-building, poor waterproof effect and short service life.
6. rubber strip
1998, Deng Yu company began to develop sealant tape and soft and hard extrusion tape for shower room. In the production of 1 1 year, Deng Yu shower waterproof tape has been continuously improved and innovated, and the most mature and best soft material formula and stable production technology have been obtained. Deng Yu adhesive tape is continuously developed in cold winter or hot summer, with no obvious change in elasticity and sealing effect and the best weather resistance. The main features are ultraviolet resistance, cold resistance and no cracking, strong air permeability and flexibility, good waterproof effect and long service life.
In addition, in cooperation with shower rooms, each series of shower rooms in Deng Yu will develop different rubber strips according to different product structures to meet the waterproof requirements of shower rooms, and will never make a patchwork to save costs. Many rubber strips used in low-grade products are recycled plastics (made of recycled materials), which have poor air permeability, many impurities and are easy to age. Because of the different formulas of raw materials, there will be yellow and brittle cracks, the overall structure is patchy, and the matching accuracy is low, which completely loses the essential role of the shower room.
7. Bottom basin
At present, the water-retaining stone base (artificial stone or marble) is the most widely used in the market for shower rooms, followed by the bottom basin, and the earliest is acrylic material. Because of its short service life, Deng Yu Company did not adopt it. In 2002, Deng Yu Company developed artificial stone bottom basin, which opened the market within two years.
Disadvantages of acrylic bottom basin: the weather resistance is poor, and the molecular structure changes during long-term quenching and heating, resulting in great brittleness. However, some manufacturers blindly pursue low quality, and adopt 2mm-thick acrylic board for manufacturing, which has low bearing capacity, which not only makes customers uneasy to step on it, but more importantly, the service life of this low-quality product is only a few months, and the service life of the best acrylic bottom basin is only about three years.
The artificial stone bottom basin corrects the shortcomings of short service life and single color of acrylic bottom basin. Although artificial stone is widely used at present, the quality of artificial stone basin is uneven at present. The main uses are as follows: a. Deng Yu adopts the best Yabang resin in China, including natural marble powder from Yunfu, Guangdong, with high quality raw materials but high price.
B, exquisite craftsmanship. Deng Yu artificial stone basin has strict requirements in mold development, trial production, mold cleaning, gel coat spraying, pouring, trimming, maintenance, polishing, packaging and other aspects, and it is different in scientific and technological content and product thickness. Testing artificial stone: Deng Yu speaks with data. Every improvement and every batch of products have to undergo rigorous testing (which is absolutely not available in other factories). The main testing equipment is the chemical laboratory testing gel coat, curing agent, resin and other raw materials. In addition, the finished product must pass the cold and hot impact testing machine manufactured by Deng Yu Company. The main measures are: spraying hot water above 78℃ for 90 seconds and stopping for 30 seconds (hot water is recovered to the hot water pool) and spraying cold water below 10℃ for 90 seconds and stopping for 30 seconds. This trip is a cyclic failure, and each test must be more than 2500 times. The surface is qualified, and there are no abnormal phenomena such as discoloration, cracks and delamination. In addition, the thickness of Deng Yu artificial stone products is 13 ~ 15 mm, which is firm and thick, with smooth surface, anti-slip design, corrosion resistance, impact resistance and easy cleaning. Dehydration has the functions of blocking prevention, deodorization and auxiliary support, and prolongs the service life. The service life of Deng Yu artificial stone products is 3 ~ 5 times that of ordinary artificial stone products.
