Introduction to Safety Glass
Safety glass refers to laminated glass, tempered glass, and insulated glass processed from them that meet national standards.
1、 What is laminated glass?
Laminated glass is a type of advanced safety glass made by sandwiching PVB film between two or more pieces of glass and subjecting them to high pressure. This type of glass has excellent characteristics such as noise reduction, impact resistance, and penetration resistance.
2、 What is colored glazed tempered glass?
Colored glazed tempered glass is a glass product with high acid and alkali resistance and high safety, obtained by printing colored glaze on the surface of the glass through special processes, drying and tempering treatment, and permanently fusing the glaze to the surface of the glass. It has the characteristics of rich color and low reflectivity.
3、 What is tempered glass?
Tempered glass is a high-strength safety glass obtained by heating the glass to its softening point and then rapidly air cooling it.
4、 What is heat strengthened glass (i.e. semi tempered glass)
This type of glass has been widely used in developed countries and is still a new product in China. The mechanical strength of its glass is several times that of ordinary glass, and its performance indicators such as appearance, flatness, thickness deviation, and light transmittance are closer to the original glass than tempered glass, overcoming the disadvantage of tempered glass self explosion.
5、 What is insulating glass?
Hollow glass is a high-performance soundproof and heat-insulating glass made by bonding two (or three) pieces of glass with an aluminum alloy cabinet containing a desiccant using a high-strength, high air tightness composite adhesive.
6、 What is hot bent glass?
Hot bent glass is glass that is heated to its softening point and processed into the desired shape.
Types of Glass
Float glass:
The production process of float glass is completed in a tin bath filled with protective gas. Molten glass flows continuously from the tank furnace and floats on the surface of the relatively dense tin liquid. Under the action of gravity and surface tension, the glass liquid spreads and flattens on the tin liquid surface, forming a smooth upper and lower surface. After hardening and cooling, it is led up to the transition roller platform. The rollers on the roller table rotate, pulling the glass ribbon out of the tin bath and into the annealing kiln. After annealing and cutting, flat glass products are obtained.
Float glass was introduced by Luoyang Glass Factory in the late 1970s in China, which was the first to introduce the Royal Float Glass Production Line from the United Kingdom. It comes out of the tin bath with glass floating on the surface of the tin solution. Therefore, this type of glass has good flatness and no water ripples. Used for making mirrors and automotive glass. One of its major advantages is that it doesn't lose face or shape.
Secondly, the mineral quartz sand used for float glass is of good quality. The glass produced is pure, white, and has good transparency. Bright and colorless. There are no glass blisters, bubbles, or the like.
The third is that the structure is compact, heavy, and has a smooth feel. With the same thickness per square meter, it is heavier than a flat plate, easy to cut, and not easily damaged. More than 30 production lines across the country strictly follow national standards to produce this type of glass, which is the best glass for civil buildings. Its price, compared to the same thickness, is only about 4 yuan per square meter higher than flat glass.
Low radiation glass:
Low radiation glass is a thin film system composed of multiple layers of metals such as silver, copper, tin, or their compounds coated on the surface of glass. The product has high transmittance for visible light and high reflectivity for infrared radiation, and has good thermal insulation performance. It is mainly used in construction, automobiles, ships, and other communication tools. Due to the poor strength of the film layer, it is generally made into insulating glass for use.
Glass mosaic:
Glass mosaic is also known as glass mosaic brick or glass paper brick. It is a small-sized colored decorative glass.
According to the national standard (GB/T7697-1996), glass mosaic can be divided into molten glass mosaic: glass mosaic mainly made of silicate and other raw materials, melted and formed at high temperature, and in a milky or milky state, containing a small amount of bubbles and unmelted particles.
Sintered glass mosaic: using glass powder as the main raw material, adding an appropriate amount of binder, etc. to press into a green body of a certain specification size; Glass mosaic sintered at a certain temperature.
Venus glass mosaic: a glass mosaic containing a small amount of bubbles and a certain amount of metal crystal particles, with obvious scintillation when exposed to light.
Characteristics of glass mosaic
It is the safest building material, made of natural minerals and glass, lightweight, and outstanding environmentally friendly material. Zero water absorption and resistance to chemical corrosion such as acid and alkali are the most suitable building materials for decorating areas near water. Can be used for decorating bathrooms, toilets, swimming pools, fountains, landscape pools, etc.
Colorful and bright, never fading, with a small size, it is the best material for making art puzzles and inlaid paintings. Using different colored mosaics can design and create the most complex puzzles, such as the pattern at the bottom of a swimming pool designed by a computer.
Construction of glass mosaic
1. Ensure that the construction surface is flat and clean, mark the reference line, and then evenly apply cement or adhesive to the construction surface.
2. Paste the mosaics in sequence, leaving appropriate gaps between each piece. After each tile is pasted, use wooden strips to flatten the mosaic, ensuring that each area is compacted and fully bonded with the adhesive.
3. Tear off the paper the next day or after the adhesive has dried. Wet the sticker with a sponge dipped in water and wait until it is completely wet before tearing off the paper.
4. Fill the gaps. Use tools to fully fill the gaps with sealant, original base adhesive, white cement, etc.
5. Cleaning. Clean the excess sealant attached to the mosaic with a wet sponge, and then wipe it with a dry cloth to complete the construction steps.
Note: The mosaic connected with plastic mesh can be constructed by laying the plastic mesh on the construction surface coated with cement, which can save step 3.
Glass mosaic is considered the smallest decoration material, and because of this, there are many possibilities for their combination and variation. For example, on a flat surface, there can be multiple ways of expression: concrete patterns, jumping or transitioning in the same color scheme, adding patterns and embellishments to other decorative materials such as tiles, and so on.
For curved surfaces or corners of rooms, glass mosaic can better utilize its small size and cover the curved surface smoothly and completely.
The size of each glass mosaic is generally 20 × 20, 25 × 25, 30 × 30 (in millimeters), and there are also varieties with rectangular or irregular edges in addition to squares.
Like paint in the hands of an artist
Choosing glass mosaic is like choosing a painter's paint. There is a "pointillism" effect in painting that is very similar to one of the decorative effects it creates. In Europe, mosaic paintings were made a long time ago, some of which are still intact today. In the ruins of Pompeii, archaeologists have discovered a "mosaic puppy" made of mosaic tiles, which provides a relatively complete record of the culture at that time.
With a distant story, the identity of glass mosaic fashionable decoration material has entered the home, whether classical or modern, as long as the owner likes it.
Not only used in the bathroom
The main components of glass mosaic are silicates, glass powder, etc., which are melted and sintered at high temperatures. It is resistant to acid and alkali, corrosion, and does not fade. The common usage is to pave the walls and floors of bathroom rooms, and there are also more clever uses.
The countertop is embedded on the surface of a stone or ceramic tile countertop, with several pieces embedded in a rhythmic or scattered pattern, serving as the finishing touch. The floor of the living room is made of mosaic tiles arranged in a square or circular shape in the sofa area, which looks like a carpet but is stronger and more durable than it; Use a mosaic curve to run through several rooms, creating a flowing feeling inside.
Replacing traditional wooden door frames or plaster moldings with door frame moldings, using glass mosaic splicing to create linear decorations, is definitely unique. Wall collage treats it as paint, allowing you to create your favorite image on the wall without worrying about it falling off. It can perfectly blend with the paint.
Wire glass:
Wire glass is also known as shatter resistant glass. It is made by heating ordinary flat glass to a red hot softening state, and then pressing preheated iron wire or wire mesh into the middle of the glass.
Wire glass, also known as steel wire glass, is glass with metal wire mesh sandwiched inside. Due to the presence of metal wire mesh inside the laminated glass, it can withstand impact or temperature fluctuations without breaking or scattering, and will not produce sharp glass fragments. It can also be fire-resistant and fire-resistant, making it a safety glass.
However, laminated glass also has some drawbacks due to the different properties of metal wires and glass. Firstly, it is prone to cracking and damage during temperature fluctuations, making it unsuitable for use near external doors, windows, and radiators; Secondly, metal wires are prone to rusting when exposed to water, and the rust extending inward can cause the glass to swell and crack; Thirdly, cutting is inconvenient. So wired glass is more suitable for indoor doors and windows.
Heat reflective glass:
Heat reflective glass is generally coated with one or more layers of thin films composed of metals or their compounds such as chromium, titanium, or stainless steel on the surface of the glass, making the product rich in color, with appropriate transmittance for visible light, high reflectivity for infrared light, and high absorption rate for ultraviolet light. Therefore, it is also known as sunlight controlled glass and is mainly used in buildings and glass curtain walls.
Heat reflective glass is commonly referred to as coated glass, typically consisting of 1-3 films coated on the surface of the glass. The shading coefficient of heat reflective glass is SC=0.2~0.6.
Maintenance methods for glass
1. Do not forcefully collide with the glass surface during normal times. To prevent scratches on the glass surface, it is best to lay a tablecloth. When placing things on glass furniture, handle them gently and avoid collisions.
2. During daily cleaning, simply wipe with a damp towel or newspaper. In case of stains, use a towel dipped in beer or warm vinegar to remove them. Alternatively, use glass cleaning agents available on the market. Avoid using solutions with strong acidity or alkalinity for cleaning. In winter, the glass surface is easy to frost, so it can be wiped with a cloth dipped in strong salt water or Baijiu with good effect.
3. Once the patterned frosted glass gets dirty, you can use a toothbrush dipped in cleaning agent to wipe it in circles along the pattern to remove it. In addition, you can also drop some kerosene on the glass or apply chalk ash and gypsum powder dipped in water on the glass to dry, and then wipe it with a clean cloth or cotton, so that the glass is both clean and bright.
4. Glass furniture is best placed in a relatively fixed place and should not be moved back and forth casually; To place objects steadily, heavy objects should be placed at the bottom of glass furniture to prevent the furniture from tipping over due to unstable center of gravity. In addition, it is necessary to avoid moisture, stay away from stoves, and isolate from chemical reagents such as acids and alkalis to prevent corrosion and deterioration.
5. Using cling film and a damp cloth sprayed with detergent can also give new life to glass that is often stained with oil. Firstly, spray the entire glass with cleaning agent, then apply cling film to soften the solidified oil stains. After ten minutes, remove the cling film and wipe it with a damp cloth. To keep the glass smooth and bright, it is necessary to regularly clean it by hand. If there are any marks on the glass, you can rub it with a rubber soaked in water, and then wipe it with a damp cloth; If there is paint on the glass, it can be cleaned with cotton dipped in hot vinegar; Wipe the glass with a clean dry cloth dipped in alcohol to make it shiny like crystal.
Precautions
1. In order to avoid unnecessary losses during transportation, it is necessary to pay attention to fixing and adding soft pads. It is generally recommended to transport it vertically. Vehicles should also pay attention to maintaining stability and slow speed.
2. If the other side of the glass installation is sealed, it is important to clean the surface before installation. It is best to use a specialized glass cleaner and wait until it has dried completely to confirm that there are no stains before installation. It is recommended to use clean construction gloves during installation.
3. The installation of glass requires the use of silicone sealant for fixation, and in the installation of windows, it also needs to be used in conjunction with rubber sealing strips.
4. After the construction is completed, attention should be paid to adding collision warning signs, which can generally be indicated by non dry stickers, colored electrical tape, etc.
5. Do not collide with sharp objects
Wipe the glass
1. Wipe the glass: First, use a towel to clean the glass frame, then use a glass scraper to dip it in diluted glass solution, evenly apply the glass from top to bottom, and repeat the above process. Use a glass scraper to wipe clean from top to bottom, and use a dry towel to wipe off any water marks left on the frame. The water marks on the glass must be wiped clean with the glass, otherwise it will leave marks on the glass one after another.
2. Mix vinegar and water in a ratio of 1:2, put them into spray, spray them on the glass and wipe them, and they will be very clean.
3. Add 5% ammonia solution or gasoline to a basin, clean the glass with it, wait for the glass to dry slightly, and then wipe it clean with a dry cloth. The glass will be spotless, shiny and transparent. When cleaning the glass, different models of window cleaners can be used to determine whether it is for double layered or single layered glass. Using a window cleaner is convenient, labor-saving, and safe.
4. If there is mold on the surface of the glass, mix hydrofluoric acid (HF) with water in a ratio of 1:8 (note: exceeding 1:8 may cause damage to the hands), and wipe the glass. Attention: Be sure to do a good job of corrosion protection, and do not let your skin come into contact with HF, otherwise it will cause serious corrosion! After wiping the glass, wipe it again with clean water and finally dry the glass.
