Boiler tempered glass is a special tempered glass designed specifically for boiler windows. Its core mission is to provide clear internal observation channels for operators under harsh conditions of high temperature and high pressure, while resisting extreme environmental erosion. It is a key component to ensure the safe and stable operation of boilers and is widely compatible with various industrial and household boiler equipment.
一 、 Core Features
1，Extreme high temperature resistance: Different from ordinary tempered glass, its temperature resistance has been specially strengthened, covering multiple gradients of 300 ℃, 500 ℃, 860 ℃, and even over 1000 ℃. It can withstand long-term high-temperature baking of boilers, avoiding softening and cracking, and is suitable for different types of boilers with different temperature requirements.
2. High strength compressive strength: Through physical or chemical tempering processes, a uniform compressive stress layer is formed on the surface, which increases the impact strength and bending strength by 3-5 times compared to ordinary glass. It can easily cope with pressure fluctuations of several megapascals inside the boiler and reduce the risk of rupture.
3. Safety protection: Continuing the safety properties of tempered glass, it breaks into uniform small particles without sharp edges, avoiding secondary damage caused by fragments under high temperature conditions and meeting industrial safety standards.
4. High transparency and adaptability: With excellent transparency, it can clearly present the combustion status and medium flow inside the boiler; Simultaneously supporting customized processing, adapting to different window sizes and installation requirements.
二 、 Mainstream materials.
1. Special sodium calcium glass (resistant to 300 ℃): High cost-effectiveness, suitable for working conditions below 300 ℃, widely used in ordinary industrial boilers and household boilers.
2. Tempered borosilicate glass (resistant to 300 ℃): With outstanding corrosion resistance, it is specially designed for boiler mirrors in special industries such as chemical, power, and petroleum.
3. High temperature special glass (resistant to 500 ℃): It can withstand thermal shock of 300-350 ℃ and is a commonly used mirror material for high-temperature and high-pressure steam boilers.
4. Ultra high temperature glass plate (resistant to 860 ℃ and above): Suitable for large observation windows or ultra-high temperature boilers without pressure requirements. Some models can withstand temperatures exceeding 1000 ℃ and are colorless and transparent without affecting observation.
三 、 Processing and Application: Comprehensive Adaptation from Process to Scene
Core processing technology。
Basic processes such as precise cutting, edge grinding, drilling, and tempering are required. In some scenarios, additional deep processing such as baking paint, screen printing, and sanding can be performed to enhance sealing and observation comfort. Each product must pass multiple tests such as pressure resistance and high temperature resistance, and meet relevant national standards and specifications before it can be put into use.
Main application areas。
Covering various types of equipment such as household gas boilers, industrial coal-fired boilers, steam boilers, garbage incinerators, chemical reaction furnaces, etc., it has become an indispensable safety component in industries such as energy, chemical, power, and people's livelihood.
