Q:What is the the best ratio of mortar in refractory cement?
The ratio of refractory cement are: M10 the ratio of cement and mortar: cement: Sand= 346kg: 1631kg M7.5 ratio of cement and mortar: cement: Sand =274kg: 1631kg M5 The mix proportion of cement and mortar: cement: Sand = 209kg: 1631kg M10 mix proportion of composite mortar: cement: Sand: Lime =306kg: 1600kg: 29kg M7.5 mix proportion of composite mortar: cement: Sand: Lime =216kg: 1600kg: 64kg M5 The mix proportion of composite mortar: cement: Sand: Lime =205kg: 1600kg: 100kg
Q:Who know what kind of fire shutter fire rating are there?
The fire resistance limit of high steel structure reduces the loss of fire, achieves remarkable results. The specification is mae in order to unify the application technical requirements of the design, construction method and quality standard of the steel structure fire retardant coating, and ensure the application effect, safety. The specifications is formulated in accordance with national engineering construction of the relevant policies and "giving priority to prevention, combining fire prevention and fire extinguishing. investigated characteristics of steel structure fire in China, summed up the experience of fire resistant coating for steel structure, and absorb domestic and foreign advanced technology and scientific achievement in fire retardant coatings for steel structures, and repeatedly solicited the relevant scientific research and design, production of construction, colleges and universities, public security department
Q:What are included in roof thermal insulation fireproofing material?
Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.
Q:How long is the duration of fire resistance that fireproof door of level B can endure?
Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof door. Fireproof door of level A can endure fire for 1.5 hours while level B 1.2 hours
Q:What's meaning of CN of fire-resistant material?
The commonly used preparation methodsinclude shock compression, high-pressure pyrolysis, ion implantation, reactive sputtering, plasma chemical vapor deposition, electrochemicaldeposition, ion beam sputtering, , low-energy ion radiation, pulsed arc discharge,pulsed laser inducing, etc. But the compounding result of superhard materialis not ideal due to deposition of amorphous CN film, nanometer level sizedC3N4 crystalline grain set in the amorphous film and few large graincrystal.
Q:Which schools are the best schools in the world for learning knowledge about refractories?
If you search on a worldwide scale, I might say you are ambitious!!! This major becomes an unpopular one and you must have to embark on graduate and PhD to specialize in it provided that you want to go abroad for further study. Wuhan University of Science and Technology may be the best school in this field with its close relatinship with many refractory manufacture factories across the country. Henan University of Science and Technology is also advisable in terms of this major, which probably promise you a job. Other universities in this regard are not quite familiar to me. You raised these questions, which shows that you are a layman to this major or not quite familiar with this major. If you have any questions, you can resort to me if I can.
Q:Why does refractory need to add coarse firstly and then add fine aggregate?
Binding agent can wrap particles and improve binding effect.
Q:Which kind of external wall fire barrier zone material is better?
I recommended foam cement and particulate thermal insulation composite waterproof material, which is fire isolation area product, which uses surface of vertical plate arranged fiber technology to make the compressive strength in the vertical direction up to above 80KPa. At the same time, under the conditions of both exterior heat insulation and effects of humiture in the long-term, it can still maintain the non-aging performance of various aspects, and safety (reliability), fire resistance and excellent durability.
Q:What are the characteristics of thealuminium oxide refractory?
Physical properties of refractories include structural properties, thermal properties, mechanical properties, performance and job performance. The structural properties of refractories include porosity, bulk density, water absorption, air permeability and pore size distribution. The thermal properties of refractories include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity and thermal emission rate, ect. Mechanical properties of refractories include compressive strength, tensile strength, flexural strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength and modulus of elasticity, ect.
Q:What is special refractories?
Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use
