Q:How is the grading of the level A new material fire insulation material?: The thermal insulation materials are generally divided into level A and level B according to the flame rating. Level A is the non-combustible material, and level B is the combustible materials. The level B material is to blame for the fire in Shenyang hotel in CCTV building a few years ago . At present, the level A materials are widely used, with some prices even cheaper than the level B material. A level is roughly divided into insulation mortar, phenolic board, rock wool board and foam cement board, ect.

Q:What are the construction measures of refractory material in winter? Please descriptive briefly.: Binding agent should be attaced great importance to when construction is conducted in winter. Generally if the bingding agent is water or cement, antifreezing measures should be taken.

Q:Fire insulation and fireproof insulation board materials What is the difference in performance?: What is the difference between fireproof insulation board and fireproof materials in their performance? Fireproof Materials prevents burning through insulating while others by chemical reactions. The overall heat conductivity coefficient of Insulation materials are generally lowered by thermal conductivity of the material itself and the structure of the material. Inorganic active insulation material uses ordinary cement, insulation stone, calcium powder, platycodon grandiflorum as the main raw material, produced after numerous tests with advanced production technology and chemical technology. Products features fire retardant,anti-aging properties and stable performance, low deformation coefficient, environmentaly friendly, compatible with the wall base layer and plastering layer. It has good security and stability and is as durable as ordinary buildings. Strong fire resistance: Fire insulation board is made of inorganic materials (cement), fireproofing level reaching to A1. As it does not burn, it is fireproof.

Q:What are the best refractory materials in 2,400 Celsius degree?: It is the purpose that decides what kind of materials you should use. What you have said is 2,400 Celsius degree, right? It is about the fire resistance of the material or the required temperature of it?

Q:What problems should be paid attention to while using refractory materials under a controlled atmosphere?: Pay attention to the performance of the materials, and the use of non oxide materials!

Q:What are the main materials in concrete fireproofing material?: it can be roughly divided into: fire-resistant coating for steel structure, finishing fire retardant paint, tunnel fire coatings, concrete fire?retardant?coating, cable refractory coating. fire-resistant coating for steel structure is divided into: Indoor ultra-thin fireproof coatings for steel structure, indoor thin steel structure fireproofing coating, indoor thick steel structure fireproofing coating, outdoor ultra-thin fireproof coatings for steel structure, Outdoor thin steel structure fireproofing coating, outdoor thick steel fireproofing coating. I hope it can help you. Hope to adopt my opinion Thank you! )

Q:What are the advantages of refractory material?: Jingute WHL type, GDS type

Q:how to classify the fireproofing material levels A1 A2 B1?: their classification is shown specifically in Fireproof? Specification of Building Interior Decoration?Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into

Q:what's the materials of fireproof?housing?: Prefabricated houses take rock wool board as its wall materials to ensure prefabricated houses and color steel mobile home reach A-class fireproofing standards.

Q:What are the main characteristics of the sic refractories?: The physical properties of SiC refractories include structural properties, thermal properties, mechanical properties, usability and job performance. The structural properties of refractory include porosity, bulk density, water absorption, air permeability, an the distribution of pore size. The thermal properties of refractory include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, and thermal emission rate. The mechanical properties of refractories include withstand voltage strength, tensile strength, anti bending strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength, and elasticity modulus. The usability of refractories include refractoriness, load softening temperature, linear?change?on?reheating, thermal shock resistant performance, slag resistance, acid resistance, alkali resistance, hydration resistance, corrosion resistance to CO, conductivity, and inoxidizability.
