Q:What's the fire endurance of A grade fireproof glass curtain wall?
The following is fire endurance of A class fireproof glass curtain wall. Fire endurance of the fire window: A class fire window: no less than 1.2h; B class fire window: no less than 0.9h; C class fire window: no less than 0.6h. Technical requirements: 1. Materials and fittings: (1) Window frame should adopt the steel frame or wood frame with certain strength so as to guarantee the integrality and stability of the fitting; (2) Steel frame and mound layer can choose the galvanized steel sheet or stainless steel sheet. Its selection standard is in line with provisions of Article 5.1 in GB12955 "General Technical Requirements on Steel Fire Doors"; (3) Selection standard of wood frame and mound layer should be consistent with the provisions of Article 5.1.1 in GB14101 "General Technical Requirements on Wood Fire Doors"; (4) Filler material inside the steel frame and wood frame should be incombustible material; (5) Fireproof glass can choose the qualified product with no influence on the fire resistance test of the fire window, and its light transmittance should be no less than 75% of that of the ordinary sheet glass with the same layers; (6) Sealing material between the frame and the fireproof glass should use flame retardant material which can play the role of fire prevention and smoke insulation in case of fire. Hope it's helpful for you.
Q:Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
Q:What is the acceptance standard of refractory?
Feeler gauge is used to check the thickness of the refractory brickwork joint. The top of the gauge can not be sharpened. Feeler gauge is of the width of 15mm, length of 100mm and thickness of 1, 1.5, 2 or 3mm. The thickness is eligible when the depth which the feeler gauge is inserted in is less than or equal to 20mm. Ten places should be inspected per 5m2 of masonry surfaces. It is qualified when the condition in which thickness of the brickwork joint is 50% larger than a predetermined depth is not less than five times and it is excellent when the condition is no more than two times.
Q:Is there anyone who can explain how to grade the level of fire insulation board?
1, Combustion performance of building material is divided into the following several class according to China's national standard GB8624-97 Class a: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect. It hardly catch on fire in the case of open flame and high temperature, do not spread fire quickly, and when the fire source is removed, fire will be stopped immediately. Class B2: Combustible building materials: Combustible materials have certain flame retardant effect. In case of fire or under high temperature, it will immediately burst into flames, easily leading to spread of fire , such as poles, wooden frame, timber, and wood stairs. Class B3: Combustible building materials: Without any flame retardant effect, will be burnt easily, resulting in high risk of fire. I Hope my answer will help you.
Q:What are the technical requirements for refractories?
How high the temperature is and what is this refractory?
Q:What are included in fireproofing materials?
Incombustible?material of construction fire-proof material Grade A: Cement, stone, steel, coat, glass, aluminium alloy, ceramic tile, etc.; nonflammable material Grade B1: Fireproof?panel, rock wool.
Q:Which manufacturers have the best fire-proof materials with light weight?
It now appears that asbestos is the best among the most common fireproof materials. But asbestos also has great harm, especially to lung. Shanghai Xinlong Fireproofing Material Co., Ltd. and Hubei Boyue Lightweight Material Co., Ltd. were established in 2009. The company is located in Wuhan Biological New Town and covers an area of ??30 acres. The company is a specialized enterprise which is mainly engaged in the research and development, production, sale and construction of lightweight partition board, lightweight fireproof wall panel and lightweight wall panel. The two companies are both good.
Q:What substitutes are available for high-end refractories in addition to zircon sand?
The composite sand powder can effectively replace zircon sand, with the same operation process, less operation time and environmental protection
Q:Are the rubber insulation materials are refractory materials?
Compared with the fireproofing properties, the main thermal insulation properties of level B1 will be carbonized and drop when it is over 200 degree. <p class="answer-refer mt-10 f-light-gray" accuse="aRefer"> Reference: It is provided from technicians of Guangzhou Ou Fu construction materials: The answer that has been got:
