What is Heat Strengthened Glass?
Heat strengthened glass is a popular choice for structural and architectural applications due to its increased strength and resistance to thermal stress. By gradually cooling the glass after moderate heating, this process improves durability. Learn more on our website.
Heat strengthened glass is an increasingly popular choice for architects, developers, and builders in structural and architectural applications. Its superior strength, safety, and durability make it an excellent material for use in windows, facades, skylights, balustrades, partitions, and other building elements that require high-performance glass solutions.
The Definition of Heat Strengthened Glass:
Heat Strengthened Glass, also known as semi-tempered glass(Silencing Check Valve), is a type of glass between regular flat glass and tempered glass. It has high strength, about twice that of ordinary float glass, but avoids some of the shortcomings of tempered glass, such as poor flatness, easy self-explosion, and overall shattering once damaged.
When semi-tempered glass(heat strengthened glass) is damaged, it will crack radially along the crack source, and there is generally no tangential crack expansion, so it can generally remain intact after damage.
Benefits of Heat Strengthened Glass
--1. High strength:
The strength of heat-strengthened glass is high, twice that of ordinary float glass. It can withstand large external impacts and is not easily broken.
--2. Resistant to rapid cooling and rapid heating:
heat strengthened glass has excellent thermal shock resistance, can withstand rapid temperature changes, and is not easy to break
--3. High safety:
When heat-strengthened glass is impacted, the fragments will stick together and will not fly around, reducing harm to the human body.
--4. Anti-riot and anti-theft:
Heat Strengthened laminated glass performs well in automotive side window applications and has anti-riot and anti-theft functions.
--5. Sound insulation, heat insulation, UV protection:
Heat Strengthened laminated glass can effectively isolate noise, heat and UV rays, providing better comfort and protection.
Disadvantages of Heat Strengthened Glass:
--1. Risk of self-explosion:
During the manufacturing process of heat-strengthened glass, due to uneven internal stress distribution, there is a certain risk of self-explosion. This self-destruction phenomenon may occur suddenly during use, posing a potential threat to the user's safety.
--2. Limited temperature difference resistance:
Although heat-strengthened glass (such as tempered glass) has a strong temperature difference resistance and can withstand higher temperature difference changes, its temperature difference resistance is still limited. For example, tempered glass can withstand a temperature difference of 200°C, but exceeding this range may still cause the glass to break.
--3. Difficulty in processing:
Heat-strengthened glass requires complex heat treatment processes during the manufacturing process, which increases manufacturing difficulty and cost. In addition, once heat-reinforced glass is processed and formed, it is difficult to undergo further cutting or other processing due to its increased hardness.
--4. Surface quality may be affected:
During the heat treatment process, the glass surface may have slight unevenness or deformation, affecting its appearance quality.
Where Heat Strengthened Glass is Applied:
--1. Building field:
Heat Strengthened glass is often used in windows, curtain walls, etc. of buildings. Because of its high strength and heat resistance, it can effectively resist wind pressure and temperature changes, improving the safety of buildings.
--2. Automobile industry:
The use of heat-strengthened laminated glass in automobile side windows can provide better impact integrity, anti-riot, anti-theft, sound insulation, heat insulation and ultraviolet protection properties to ensure driving safety
--3. Household items:
Heat-strengthened glass is also used to make household items such as coffee tables and cabinets. Because of its high temperature resistance, it is suitable for use in high temperature environments.
--4. Other fields:
Heat-strengthened glass is also used in radiators, gas stove heightening panels, water heater outlets and other occasions that require high temperature resistance
Technical Standards for Heat Strengthened Glass:
The surface compressive stress of semi-tempered glass(heat strengthened glass) is between 24MPa and 52MPa, and the surface compressive stress of tempered glass is greater than 69MPa. The production process of semi-tempered glass(heat strengthened glass) is the same as that of tempered glass. The only difference is the air pressure at the quenching station, and the cooling energy is smaller than that of tempered glass.
In conclusion, the market for heat-strengthened glass is expanding rapidly, driven by the increasing demand for high-performance, energy-efficient, and safe building materials. The market hotspots for heat-strengthened glass are the Asia-Pacific, Middle East, Africa, North America, and Europe regions, where the construction industry is booming. The major players in the market are investing in research and development, production capacity, and distribution network to meet the growing demand for heat-strengthened glass in various building applications. Those who invest in heat-strengthened glass now may reap the many benefits available in the market.
