- Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
- Ceramic pottery ceramic collectively known species of high water absorption and low-grade sinter clay brick, tile-like material; high stone kinds of porcelain clay plus clay and other raw sintered body strength, low water absorption bowls, plates and other kinds of refractory high temperature structural materials are all non-machine ceramic refractory metal material belonging to a broader definition of ceramic refractory ceramic can be attributed to the high temperature ceramic refractory.
- Q:What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?
- Alkali resistant castables cost the least.
- Q:What are the main components of refractory cement?
- SiO powder is often used. Ultra-fine powder refers to less than 1 / zm particles which are made by hydrolysis of ethyl silicate or made from recycled dust in the smelting process of ferro-silicon alloy. Non-cement castable refractory are castable refractory material which contains no cement instead it relies on the coagulation and combination by adding ultra-fine powder or sol (see refractory castable), and it is an amorphous material with high activity. Silica sol is made through Ion-exchange of sodium silicate after Na ions are removed. The easiest method is to prepare by reaction of aluminum metal with hydrochloric acid or alchlor. It is a thermodynamically unstable system which has certain requirements for ultra-fine powder and sol. It is different from non-cement refractory castable, Cr2zrOz and etc. It has low impurity content, and can bond with itself, so it has good binding strength. Ultrafine powder used in non-cement castables are SiO2, Al2O3, Cr2zrOz, etc. Such recycled SiO2 powder has an average particle diameter of 0.5 pm, therefore when adding the gelling agent (electrolyte), it can coagulate and give the products some bonding strength. Non-cement castable refractory is made up of refractory aggregate and powder and it is round. Since the use of superfine powder or sol as binder. The size of sol particles are of 0.1 ~ 1 m. Non-cement refractory castable takes oxide or synthetic compound ultra-fine powder or oxide sol-gel which is similar to the chemical composition of material in tungsten castable. There are several ways to prepare alumina sol. The sol used are mainly alumina oxide and silica sol. The surface area is large, and it helps to improve high-temperature structural strength. Non-cement castable refractories rely on oxide ultra-fine powder or sol to coagulate and combinate. It is a refractory castable (also known as chemical bonding castable) which uses chemical binder instead of cement for combination.
- Q:What crusher is used for raw material of broken refractory material? What is the rough crushing process? What are the materials? Thank you!
- Common faults and causes of magnetic?separator. 1. Motor of magnetic?separator is overheated and its sound is not normal. Reasons for this failure are: 1) lubrication of bearing is bad or badly worn; 2)fan blade falls off or wears; 3)bad contact of switching circuit or disconnected to run a single phase; 4) voltage is too low. 2. Reasons for this failure due to overheated speed reducer are: 1) lack of oil or poor kerogen; 2) wear between gear and worm, or poor mesh; 3)poor lubrication of bearing or serious wear. 3. The sound of magnetic?separator during operation is abnormal, lattice ball mill. Cylinder is stuck by obstacle, and even the cylinder can not rotate. The bottom box vibrates. Reason for this failure is often that it is stuck by objects in drag flask, otherwise magnetic?patch falls off so that the cylinder screaks and pierce tube when it is serious. At this time, car should be stopped for maintenance and troubleshooting. Only when we master common faults and reasons of magnetic separator can we timely identify problems and solve problems. Better maintenance and repair of magnetic?separator equipment are an important prerequisite to properly use equipment and ensure the construction.
- Q:Which industry does the metallurgy and thermal insulating and refractory material belong to?
- According to "New Economic Industrial Classification", the metallurgy and the thermal insulation refractory matter belong to C category. The manufacturing industry has 30 categories. The non-metallic mineral products industry has 303 classes. The production of building materials of tiles, stones, ect. refers to clay, ceramic tile production, building stone processing, building materials produced by wastes or drogs and subcategories 3035 produced by other building materials. The manufacture of thermal and acoustic insulation materials refers to the manufactuer of mineral insulation materials and other products, like rock wool, mineral?cotton, expanded perlite and expanded vermiculite used for thermal insulation and sound insulation, but it does not include the production of 3039 subcategories, like asbestos thermal insulation and sound insulation materials, and other construction materials.
- Q:how to classify Insulating Refractory ?
- General materials have test reports, where fire rating is labled.
- Q:What are the best refractory materials in 2,400 Celsius degree?
- You can try zircon sand which has a melting point of 2430.
- Q:What kind of refractory material should be used for common boiler?
- Build by using clay refractory mortar. Common clay brick is used as combustion layer. Xindeyuan Refractory Material, red?brick is used as external wall. Light clay brick is used as thermal insulation layer, thank you.
- 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㎜).
- Q:what's the fire endurance of fireproof?panel?
- fire endurance of fireproof?panel generally is 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof?panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof?panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.
