The glass family can be roughly divided into the following four categories:
a clean piece of glass;
Two decorative glass;
Three safety glass;
Four energy-saving decorative glass;
a clean piece of glass;
The so-called clean glass refers to flat glass without further processing;
The thickness size is from 3~12mm; our common framed doors and windows generally use 3~5mm;
Generally, partitions, windows, and frameless doors are mostly 8~12mm;
Clear glass has good perspective and light transmission performance. The transmittance of heat rays in sunlight is relatively high, but it can effectively block the long-wave rays generated by indoor walls, roofs, grounds and objects, so it will produce a “warm house effect”. This warming effect is actually a derogatory term. The direct impact on the room is that the air conditioner will consume more energy in summer and the insulation effect will be poor in winter.
Even so, it is the original film of the following types of glass deep processing
2 decorative glass
As the name implies, it is colored flat glass, glazed glass, embossed glass, sprayed glass, milky glass, carved glass, and iced glass that are mainly decorative. They are basically of the flower family.
Triple safety glass
Homogeneous tempered glass, tempered glass, laminated glass, fireproof glass, there are four main categories
In addition to flat glass, tempered glass should be the most heard in our daily life. Flat glass is tempered in a glass factory, and the tempering time takes about a week.
The tempered glass is like ordinary people wearing armor, with high strength and strong impact resistance. The elasticity is also much larger, and it is not easy to burst, and it is not easy to hurt people after being broken. Generally, tempering measures are required for large-area glass curtain walls.
Usually public areas have safety-required doors and windows ~ partition walls ~ curtain walls! Tempered glass will be used for windows~furniture, etc.
After ordinary glass is tempered, a stress layer is formed on the surface. The glass has improved mechanical strength, thermal shock resistance, and a special state of fragmentation.
However, the shortcoming of tempered glass is easy to self-explode, which limits its application. After long-term research, it is found that the presence of nickel sulfide (Nis) stones inside the glass is the main reason for the self-explosion of tempered glass. By homogenizing tempered glass (the second heat treatment process), the self-explosion rate of tempered glass can be greatly reduced.This is the origin of homogeneous tempered glass
We know that it is homogeneous tempered glass when we see the HST letter on the glass
Laminated glass is between two or more pieces of original glass, and the intermediate material mainly made of PVB is heated and pressure-bonded to form a flat or curved surface that conforms to glass products.
The number of layers is 2.3.4.5 layers, up to 9 layers. The laminated glass has good transparency and high impact resistance, and the broken glass will not scatter and hurt people.
Fire-resistant glass refers to safety glass that can maintain its integrity and thermal insulation during the specified fire resistance test.
According to the structure, it can be divided into composite fireproof glass (FFB) and single piece fireproof glass (DFB)
According to the fire-resistant performance, it is divided into heat-insulating type (Class A) and non-heat-insulating type (C-type), and can be divided into five grades according to the fire resistance level, and the fire resistance time is not less than 3h, 2h, 1.5h, 1h, 0.5h.
Four energy-saving decorative glass;
Colored glass, coated glass and insulating glass are collectively referred to as energy-saving decorative glass, referred to as “color film empty”
Tinted glass can not only absorb heat rays in sunlight significantly, but also maintain good transparency and energy-saving decorative glass. Also called colored heat-absorbing glass. Not only can it effectively absorb the sun’s radiant heat, but also produce a “cold room effect” to achieve the effect of heat shielding and energy saving.
It can soften the passing sunlight and avoid glare from absorbing the sun’s ultraviolet rays. Prevent the fading and deterioration of indoor items and keep the items bright. Increase the appearance of buildings. Generally used for doors and windows or curtain walls of buildings.
Coated glass has a certain control effect on the heat rays of sunlight, has good heat insulation performance, and can avoid the greenhouse effect. Save energy consumption of indoor cooling air conditioners. It has one-way perspective and is also called SLR glass.
Interrogation rooms are widely used in film and television dramas
Low-E film glass is also called “Low-E” glass.
This kind of glass not only has high light transmittance, but also can prevent rays. It can make the room warm in winter and cool in summer, and the energy saving effect is obvious.
However, this kind of glass is generally not used alone, and is usually combined with clear glass, float glass, and tempered glass to make high-performance insulating glass.
Hollow glass is characterized by good optical performance and good sound insulation performance.
It is mainly used in buildings with functional requirements such as thermal insulation and sound insulation.
