Toughened glass, also known as tempered glass, is a type of safety glass that is significantly stronger than ordinary annealed glass. Understanding its meaning in Hindi and its various applications is crucial for making informed decisions in construction, automotive, and other industries. This article explores the “toughened glass meaning in Hindi,” its manufacturing process, benefits, and common uses.
Understanding “Toughened Glass” in Hindi
The Hindi translation for toughened glass is “तपाया हुआ कांच” (tapaya hua kaanch). This literally translates to “heated glass,” accurately reflecting the core process of its creation. Other terms used include “कड़ा कांच” (kada kaanch) meaning “hard glass,” and “सुरक्षा कांच” (suraksha kaanch), which means “safety glass.” While these terms capture the essence of toughened glass, “तपाया हुआ कांच” (tapaya hua kaanch) remains the most accurate and widely used term. Knowing these various translations can help you navigate conversations and materials related to construction and other related fields in India.
How is Toughened Glass Made?
Toughened glass is created through a controlled thermal process. Normal annealed glass is heated to extremely high temperatures, then rapidly cooled using air jets. This rapid cooling creates compressive stress on the surface while the core remains tensile. This balanced stress profile gives toughened glass its enhanced strength and characteristic shattering pattern.
Benefits of Using Toughened Glass
Toughened glass offers several advantages over regular glass, making it a preferred choice in various applications:
- Increased Strength: It’s up to five times stronger than annealed glass, resisting impacts and bending forces.
- Safety: Upon breakage, it shatters into small, relatively harmless granular chunks, minimizing the risk of serious injuries.
- Heat Resistance: It can withstand higher temperatures compared to annealed glass, making it suitable for applications involving heat exposure.
Common Uses of Toughened Glass
The strength, safety, and heat resistance of toughened glass make it ideal for diverse applications:
- Automotive Industry: Windshields, side windows, and rear windows in vehicles.
- Construction: Glass facades, skylights, balustrades, and shower enclosures.
- Home Appliances: Oven doors, refrigerator shelves, and cooktops.
- Furniture: Tabletops, shelves, and display cases.
Toughened vs. Laminated Glass: Key Differences
While both offer enhanced safety, toughened and laminated glass differ in their construction and properties. Toughened glass, as explained, is heat-treated. Laminated glass comprises two or more layers of glass bonded together with a layer of polyvinyl butyral (PVB). Upon impact, laminated glass may crack but typically remains intact due to the PVB interlayer, while toughened glass shatters into small granules.
Conclusion
Understanding the “toughened glass meaning in Hindi” – तपाया हुआ कांच (tapaya hua kaanch) – is essential when considering glass options for various needs. Its superior strength, safety features, and heat resistance make it a versatile material for applications ranging from automotive to architecture and household appliances. Choosing the right type of glass ensures safety and durability.
FAQ
- What is toughened glass called in Hindi? It’s commonly known as “तपाया हुआ कांच” (tapaya hua kaanch).
- Is toughened glass expensive? While generally more expensive than annealed glass, the added safety and durability often justify the cost.
- Can toughened glass be cut or drilled after tempering? No, attempting to cut or drill toughened glass after the tempering process will cause it to shatter.
- What are the disadvantages of toughened glass? It can be more susceptible to spontaneous breakage due to nickel sulfide inclusions and cannot be modified after tempering.
- Is toughened glass the same as safety glass? Toughened glass is a type of safety glass, but other types, like laminated glass, also exist.
- Where can I buy toughened glass in India? Numerous glass suppliers and fabricators across India offer toughened glass.
- How do I identify toughened glass? Look for a small, almost invisible marking or stamp usually located in a corner, indicating that the glass is tempered.
