FACTORY:
- Q: Who knows about the fire endurance of A grade fireproofing glass doors?
- The fire endurance of A grade fireproofing glass doors should be no less than 3 hours. A grade fireproofing glass doors use common glass of 6 mm. The shock resistance of float glass is about less than 5 min, and that of toughened glass is about 15 to 30 min. Fireproofing glass is classified in accordance with fire rating, the fire endurance of which is usually from 30 to120min, and that of the most common fireproofing glass is 60 to 90min, but now the market is a mixed bag, the so-called fireproofing glass is generally fake ultra-strong tempered glass. Therefore, you should buy the genuine glass with formal certificates, or you will bring yourself great inconvenience, and even more serious consequences.
- Q: What is the fire resistance thickness of the thin fire-retardant coatings?
- There is no detailed requirement on the thickness of the thin steelwork fireproof coatings in the "Code for application technology of steelwork fireproof coating", and the thickness there refers to a certain thickness which must(at least) have fire resistance for a certain time. The thickness of fireproof coatings in engineering generally depends on the manufacturer's test reports. Our thin steelwork fireproof coatings: the fire resistance is 2.5 hours, the thickness is 4.9 mm, the fire resistance is 2.0 hours, the thickness is 3.5 mm, the fire resistance is 1.5 hours, the thickness is 1.75 mm, the fire resistance is 1.0 hours, the thickness is 1.17 mm.
- Q: What are the fire protection standards of insulation materials?
- This question is, like this. The combustion performance of thermal insulation materials for exterior walls of all civil buildings, within the scope of fire design auditing and fire control acceptance, should be brought into the auditing and acceptance. As for the "Management Regulations on Supervisions of Fire Prevention and Control for Building Projects" (Ministry of Public Order No. 106) , all civil buildings which are out of the scope of Article 13 and 14 are included in the random check. Before the release of new standard, it must be strictly implemented the Article II of the "Fire prevention Interim Provisions on civil external wall insulation system and external wall decorative" ([2009] No. 46), namely, the insulation materials of civil buildings must use materials with A-level combustion performance.
- Q: How long is the fire resistant limit for ultra thin fire retardant coating?
- According to the "code for fire protection design of tall buildings", the fire resistance time of the component is at the first level: 3 hours, beam: 2 hours, floor: 1.5 hours;if fire resistance level is level 2, the requirement for time of fire resistance component is the column: 2.5 hours, beam: 1.5 hours, floor: 1 hours. For fire resistant coating, fire resistance time for ultra-thin fire retardant coating is less than 1.5 hours. If the time exceeds 1.5 hours, thick fire resistive coating should be uesd.
- Q: What's the organzational structure of refractory material?
- Although hacing same chemical composition refractory material products also is mineral organizer. There are differences in the type of mineral phase, high refractoriness under load, quantity and crystalline state. The organizing minerals and microstructure are reflected by folding strength, high temperature pit definite density torsional strength, high-temperature torsional strength and product property. But, for example, wear or crack may cause damage. The performance index can reflect the internal structure of refractory: the nature of the thermal performance---linear expansion coeffcient. And the mineral composition of refractory material depends on the chemical composition and process conditions, the heat capacity and temperature conductivity. If the processing conditions are different, the influence of chemical action, and thermal conductivity: represents the nature of the mechanical properties - normal temperature, high temperature compression strength, high temperature creep performance and elastic modulus. Chemical compositions are the basic characteristics of refractory, representing the nature of the density---porosity, corrosion occurred refractory materials in high temperature use As a result, the composition and quantity directly determines the performance of refractory, true density: representing the forming of high temperature performance --- refractoriness, high temperature volume stability, so you can't analyze the effect on the product performance just from chemical composition. The performance of various refractory materials are different. It must be emphasized that macroscopic organization structure of refractory material is also an important factor that affects performance; reflecting complexity of penetration---air permeability, thermal shock resistance and slag resistance. The main component is the foundation of refractory characteristics.
- Q: How is the fire endurance of the fireproof paint?
- second level firerpoof of cooling rack. with a fire endurance from 1 to 1.5 hours. According to the code for fire protection design of buildings. 1. fireproof grading of first level is 1.5 hours 2, fireproof grading of second level is 1.0hour.
- Q: How many fire endurance grades are the AAA fire resisting shutter divided?
- The different fire resistant levels of the building have different requirements of the fire endurance of the building component. According to the fire endurance, the fire doors can be divided into Class A, Class B and Class C fire doors with the fire resistances are not less than 1.20h, 0.90h and 0.60h. Even the fire resistant level of B can also use the first rate fire resistant door.
- Q: What is shapeless refractory with high performance?
- The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
- Q: The manufacturing technique of refractory material
- Melt blowing method is to melt the ingredients first, In addition, hiphotos, organic impurities, to be mixed, add sulfite pulp waste liquid into magnesia billet , ensure the accuracy of the product dimension. The products are mainly used for light refractory. then dry and fire with sintering to reduce the firing shrinkage of products, making it disperse into fiber or hollow sphere. The porpose of pre sintering raw material is to Sintering method is pre-sintering part of the raw material into clinker. such as adding binding clay into aluminum silicate blank
