Q:What is the main material of fireproof wooden door?
Fireproof wooden door has a lot of materials! including imported timber decorative effects: utilizing the diversity and easiness to cut of the timber, with all the decorative characteristics of the timber. Material selection features, door frames: Using high-quality hardwood, such as imported miscellaneous wood, camphorwood, lauan, hemlock, etc., insetting fire and smoke proof adhesive tape
Q:What are fireproofing materials?
1. Fire-resistant coatings like finishing fire retardant paint, fire retardant coating member and fire-resistant coating for steel structure; 2. Fireproofing materials of flame-retardant plastics and plastic products, textiles, flame retardant fabrics, building materials and products, flooring materials, and wall insulation system; 3. Fireproof element of fireproof panels, fire doors, fire resistant window frames, fire resistant shutter, fire-resistant glass, elevator landing doors, ventilation ducts, fire-proof sealing materials, and fire protection smoke exhaust fans.
Q:I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?
the fire endurance of fire window is: class A window is not less than 1.2 hours, class B window is not less than 0.9 hours, Class C window is not less than 0.6 hour. technical requirements: 1, materials and accessories (1) the window frame is made by a certain strength of steel frame or wooden frame which is sufficient to safeguard the integrity and stability. (2) steel frame and mound layer can select galvanized steel sheet or stainless steel plate. Its selection standards should be in line with the provisions of Article 5.1. in GB12955 "Steel Fireproof Door General Technical Condition" (3) the selection standards of wood frame and mound layer should be consistent with the provisions of Article 5.1.1. in GB14101 "General Technical Conditions of Wooden Fireproof Door" (4 ) the inner filling material of steel and wood frame should be non-combustible material. (5) fireproofing glass can choose the qualified products in fire resistance test and not affecting the fire windows. light transmittance of glass is not less than 75% of identical layers of ordinary plate glass. ( 6) a sealing material between the frame and the fireproofing glass should use the nonflammable material, it can play the role of fireproofing and smoke insulation in the fire disaster. I hope I can help you
Q:What are the types of refractory sealant?
1. The characters of sealant for construction According to the characters, sealant for buildings are classified into caulk, sealants and construction sealant in China; They are named in accordance with the function and different basepolymeters. In the relevant standard for products,
Q:Does the aluminum silicate thermal insulation material fireproof?
With stable performance,long fiber length, strong tensile strength, strong seismic performance, low shot, light unit weight, low thermal conductivity, good insulation properties. it is not bad.
Q:What are the main components of refractory cement?
Refractory cement, also known as aluminate cement, can also be gray. Aluminate cement is often yellow or brown. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc.
Q:What's the A grade fireproofing material?
Main materials are steel, wood, steel and wood. Fire door is one of the measures for buildings fire separation, and it is generally installed at the firewalls, entrances and exits of stairwells or tube well openings, which is required to play the role of fire protection and smoke control. Fire door plays an important role in preventing the spread of smoke and fire and reducing damages, so it must be strictly required. Fire dooor is classified into three classes of A, B, C, and their fire insulation and fire integrity is greater than or equal to the following values: A class fire door: 1.5h; B class fire door: 1.0h; C class fire door: 0.5h. It is in accordance with the provisions of Article in GB12955-2008 "New Standard of Fire Doors".
Q:What are the types of advanced refractory?
it can be divided into two categories of general and special refractories ordinary refractories by chemical properties into acidic, neutral and alkaline. Special refractory composition divided by high temperature oxide, refractory compounds and high-temperature composite materials Furthermore, according to refractoriness can be divided into ordinary refractory products (1580 ~ 1770 ℃), advanced refractory products (1770 ~ 2000 ℃) and grade refractory products (2000 ℃ above). the article can be divided into blocks (standard bricks, shaped bricks, etc. ), special shape (crucible, sagger, pipe, etc.), fibrous (aluminosilicate, zirconia and boron quality, etc.) and a random shape (refractory clay, pouring materials and ramming mixes, etc.) according to the sintering process it can be divided into sintered products, cast products, melt blown products.
Q:What refractories are resistant to fluorine gas?
It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
Q:How to distinguish the fire resistant level of the rubber and plastic thermal insulation material?
Level A of non-combustible insulation materials are: W W inorganic active wall insulation materials, cement foam insulation board, glass beads of insulation mortar, rock wool board, glass wool board and foam ceramics, ect. Th e level A is non-combustible material, characterized with low density, low thermal conductivity, high bearing capacity, convenient construction, economy and durablity, and widely used as the thermal insulation materials in hot pipes, thermal equipment and other pipe-line equipment and industrial architectures, and as the thermal insulation, heat insulation and sound-absorbing materials in industrial and civil building envelope. Because of its good thermal stability, it is more used as fire-resistant protective coating material of steel structure.
