Q:What's the fire endurance of hollow brick?
For hollow brick wall, it should be noted that outside are 200-thick coal gangue hollow brick wall on interior wall. Besides, the fire endurance should comform to GB50067-97 Fireproof code for garage, repair garage, parking lot design. 3), All joints of brick walls and concrete wall column should reserve rebar tie. Masonry mortar in internal and external walls should be full. Wall masonry should be up to bottom of beam slab and filled tightly with 1:3 cement mortar.
Q:What are the raw materials of refractory? And what are their names?
Q:What material is used for making refractory stone bowl?
It can be natural stone or synthetic material (referred to as synthetic stone). If chosen improperly, some natural stones will separate out the minerals which cause gastrointestinal discomfort on sensitive people. Synthetic material has great output with relatively high safety and it is stronger than ceramic casserole. Now stone pot of synthetic material is mainly used in South Korea.
Q:What are the specifications of fireclay bricks?
Specifications of fireclay bricks are shown in the figure;
Q:What kind of fireproof material is used for steel structure?
Brushing or spraying the coating on the surface of steel structure to prevent burning and insulate heat. It also prevents undermining the rolled steel from rapid temperature elevation and avoid collapse of building for lose of supporting capacities. Agglutination material are classified as fireproof coatings for steel structures which is solvent based and Water-based steel structure fire retardant coatings. Fireproof coatings for steel structures which is solvent based are subdivided into fireproof coatings for steel structures which is solvent based with low benzene content and fireproof coatings for steel structures which is solvent based with high benzene content (TVOC≤600g / L, benzene ≤5g / kg). It can be divided by thickness. ultra-thin (CB) fireproof coatings (coating thickness ≤3mm), thin (B) fireproof coatings (3mm & amp; lt; coating thickness ≤7mm) and thick (H) steel structure fire retardant coating (7 mm & amp; lt; coating thickness ≤45㎜). The coating can be divided into non-intumescent fire retardant coating and intumescent fire retardant coating according to the the expansion properties. Slim (CB) and fire-resistant coating for steel structure and thin(B) fireproof coatings is intumescent fire retardant coating, thick (H) fire-resistant coating for steel structure is intumescent fire retardant coating. Unprotected steel structure has fire endurance of 0.25 hours.
Q:I wanna ask you, which level is b1 fireproof and thermal inuslation matertial ??
I soppose you mean rubber and plastic! Only rubber and plastic has b1b2 level. Level b1 is the fireproofing level b1, because the rubber and plastic does not belong to the fireproofing material. It only has fire retardant. The wholesale of all kinds of thermal insulation material and construction need to look at the name, hope you adopt.
Q:How to choose construction external wall thermal insulation and fireproofing materials?
Now external wall insulation decoration one board is more popular thermal insulation material. Low-carbon energy-saving insulation decoration board combine two constructions (decoration, insulation) into one, saving nearly ten processes,and construction period. Compared with conventional thermal insulation methods, it can increase construction efficiency one time by shortening 60% of the construction period. It integrates low carbon, energy conservation, decoration, fireproof and building aesthetic effect by combining like-dissolving-like binding system installation and bump fixed system, and under long-term cooperation of air handling system and waterproof system. It has excellent outdoor weather resistance, colour retention, alkali resistance, water resistance, scrubbing resistance, crack resistance and temperature change resistance, wear resistance, collion resistance and the paint film is firm and durable, with strong adhesive force and mould proof effect. It can provide all-dimensional thermal insulation, decoration, low carbon and energy conservation and fire prevention for construction projects.
Q:What's the type of fire proofing thermal insulation materials?
Hello! Fire proofing thermal insulation material can be classified as inorganic thermal insulation material and composite thermal insulation material. According to the form, it can be divided into fibrous veneer, mineral wool, rock wool, glass wool, aluminum silicate cotton, ceramic fiber, microporous diatomite, calcium silicate, expanded perlite, expanded vermiculite, aerated concrete, bubble foam glass, ash, glass, clay, foam concrete, and pasted paste powder polystyrene particles insulation pulp, etc. They are characterized by flame retardancy and fire proofing and thus can be used in buildings with high fire proofing class. Among them, calcium silicate, aluminum silicate and asbestos can also be used for the thermal insulation for heat supply pipelines.
Q:What needs to be paid attention to in the construction of high- temperature refractory mortar?
As far as I'm concerned, in the construction of high-temperature refractory mortar, these matters should be noted: 1. During the use of high-temperature daub masonry stove, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 2. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 3. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting.
Q:Are refractory materials and fireproofing materials the same?
Both refractory materials and fireproofing materials belong to the industry of construction materials and each of them can also be treated as an specific industry.
