ComprehensiveProfessional GlassClassification and Use

Preface

Glass is not only a transparent material, but also has unique transparency and plays an important role in various fields of our lives. It is rich in functions. Whether it is used in home or architectural design, or in industry, military, national defense research, energy production, ecological environment, and modern communication technology, no other material can be as versatile as glass. Currently, internationally, the past classification methods for glass and glass products have changed and can basically be divided into two categories: traditional glass and new glass.

1. Traditional glass

Traditional glass refers to glass materials and products corresponding to traditional industries, mainly including flat glass and daily glass.

1. Flat glass

Flat glass refers to plate glass products whose thickness is much smaller than its length and width, and whose upper and lower surfaces are parallel. Its output and use occupy a very important position among various glass products. Internationally, people generally classify flat glass in five ways: thickness, shape, processing method, function and use.

(1) Classification by forming

Float glass, large flat-drawn glass (also called grid method) glass, small flat-drawn glass, vertical grooved glass, vertical non-grooved glass, Asuka grooved glass, rolling glass.

(2) Classification by thickness

Ordinary flat glass (4-8mm), thin glass (1.5-3mm), ultra-thin glass (1.5-0.lmm), extremely ultra-thin glass (0.1 mm), thick glass (8-12mm), extra-thick glass (12 -19mm), extra thick glass (19-30mm).

(3) Classification by processing

Raw glass is also called flat glass that is directly formed once; deep-processed glass is also called secondary processed glass.

(4) Classification by color

Colorless flat glass, colored flat glass, opal flat glass, colored opal flat glass.

(5) Classification by function

Ordinary flat glass (lighting, windshielding and thermal insulation), high-strength glass, heat-absorbing glass, heat-insulating glass, heat-reflecting glass, low-emissivity (Low-E) glass, infrared-absorbing or infrared-transmitting glass, visible light selective absorption glass, microwave absorption glass glass, absorption

X-ray or Y-ray absorbing glass, soundproof glass, fireproof glass, anti-theft glass, conductive glass, electromagnetic radiation shielding glass, self-cleaning glass, photochromic glass, thermochromic glass, luminous glass, smart glass, etc.

(6) Classification by use

Building door and window glass, glass curtain wall, glass mirror, safety glass (tempered, laminated, wired glass), fire-resistant glass, anti-theft glass, windshield glass (used for windshields in cars, airplanes, and ships), porthole glass (transportation vehicles, aerospace Portholes on aircraft), display substrate glass (liquid crystal display LCD, plasma display, PDP, electroluminescent display ELD, electroluminescent display FED) plate making glass (photographic plate making, precision scale, holography, spectrum microscopy Photography, space precision technology), integrated circuit substrate glass, magnetic disk and optical disc substrate glass, solar cell substrate and cover plate, cover glass for instruments and watches, lighting glass, filter glass and various decorative glass.
