With the development of modern society, living standards continue to improve; doors and windows are also constantly improving and progressing, the original basic function of doors and windows is lighting, anti-theft; now on the basis of the original promotion of environmental protection, recycling of renewable resources, so the aluminum alloy system doors and windows should be the general trend , get applied by Everbright;
First of all, we consider the safety performance of doors and windows from the glass, and the glass is changed from ordinary single glass to insulating glass or laminated safety glass;
Many consumers will ask whether the glass is tempered glass, whether there is a ccc mark, whether the glass has inert gas, etc.;
So how do we distinguish safety glass? A special feature of tempered glass is that there are ccc tempered marks and a series of numbers on the glass. This number is the code assigned to the tempering factory by the National Glass Inspection Center. It is automatically added by the machine during tempering, and then tempered together with the glass through high temperature furnace processing, such marks are difficult to erase; some small manufacturers will use silk screen printing pigments to fake tempered glass on glass in order to shoddy, such marks will be scratched off lightly; this It is very simple and intuitive to check whether the glass is tempered;
If it is an engineering project, an experiment will be carried out to determine whether the tempering degree of the glass is qualified. Generally, the door and window construction drawings of engineering projects will have mandatory requirements for the glass; Square meters, the glass below 900mm from the ground shall be forcibly tempered; after the glass is broken, the particles shall not be larger than 2cm;
In order to save costs and increase profits, some manufacturers do not reach the time or temperature when tempering glass, but only temper it for tempering, completely disregarding the safety of property and life. Such tempered glass will be broken into large pieces. The fragments are also very irregular. If this type of glass is broken and falls from a high altitude, it is very dangerous and cannot meet the standard of safety glass;
So when you buy door and window glass, you can check the tempered serial number of the glass on the relevant website. There is only one, and it cannot be faked. For the safety of the public's property and life, we strongly urge all consumers to be strict when choosing glass;
In addition, laminated glass must be used for high-altitude planes, such as the top, aisle, and frameless, and it should be dry-clipped instead of wet-clipped; in fact, there is no concept of wet-clipped glass in the industry, but some businesses use it for profit. The name of the wet clip is just such a concept. The wet clip glass is like gutter oil. It is just oil, not only not nutritious but also harmful;
Wet laminated glass and dry laminated glass can be distinguished directly from the senses, because dry laminated glass uses a film that is heated at a high temperature to melt the film so that two pieces of glass can be pasted together, and wet laminated glass is to use glue to stick two pieces of glass together. There is a lot of oil during installation, and the glass will be very blurred; dry laminated glass is just the opposite, and the film in the middle can be seen directly;
