EnglishAnalysis on the structure and advantages of glass fire door
Fire doors are different from ordinary doors, which have special uses. The fire door has the function of general door, and also has the function of preventing the spread of fire and the extension of smoke. The fire door is obtained after special processing. It can meet the fire resistance stability, integrity and heat insulation together within a certain time. In case of fire, it can protect the temporary safety of personnel and strive for rescue time.
Glass fire door is a kind of fire door. According to the classification of fire resistance, fire doors can be divided into class A, class B and class C. The fire resistance time is 3h, 1.5h and 1H respectively. Glass fire door belongs to class a fire door. It is fire-resistant, sound insulation and high light transmittance.
The glass fireproof door shall be composed of fireproof glass, steel structure, hardware accessories, etc. Fireproof glass and steel structure are the main parts. Structure of fireproof glass:
1. Selection of fireproof glass: the fireproof glass is divided into different grades according to the fire resistance time, and the fireproof glass is selected for the glass fireproof door. When the glass is baked at high temperature, the fireproof adhesive in the glass will change the original state, gradually blister and swell until carbonization, and then form a thermal insulation layer with low thermal conductivity, so as to prevent the flame and smoke from extending from the fire area to the back fire area, and reduce the heat radiation of the flame to the back fire area.
2. Select steel structure or stainless steel structure: the steel structure has the characteristics of solid, fire-resistant and heat insulation, poor single insulation function and sealing function, poor corrosion resistance, climate change, easy aging for a long time, and less color selection of steel structure; Compared with steel structure, stainless steel structure has rich color choices: ① titanium ② 8K mirror ③ rose gold ④ 304 sand plate ⑤ black titanium, which can be selected according to demand; The fire resistance of stainless steel structure is not as good as that of steel structure at a certain time, but the weather resistance is good, and the use color will not change.
Other accessories of glass fire doors shall be made of fireproof materials, and hardware accessories shall be qualitative supporting products that pass the test.
Glass fire doors shall be set in fire compartment, evacuation staircase, machine room, warehouse, oil depot and other important fire passages and flammable and explosive public places. Sichuan Dasi special glass technology Co., Ltd. is a good manufacturer of glass and fireproof glass. The factory has developed for decades, with a plant area of more than 10000 square meters, various testing statements and quality assurance.
