- Q: What is fireproof concrete?
- Silicate fireproof heat-resistant concrete using temperature can reach 700 DEG ~800 DEG, the main mechanism of its heat is dehydrated calcium hydroxide silicate hydrates series of cement clinker under high temperature, the calcium oxide and slag and mixing activated silica material in the three and two aluminum oxide and the reaction of anhydrous calcium silicate and anhydrous aluminum acid calcium has strong heat resistance, the fire resistance of concrete is a certain. Such as the use of high alumina bauxite and broken bricks, magnesia brick and magnesia for fireproof heat-resistant concrete materials with the highest using temperature can reach 1100 DEG C.
- Q: What is the heat preservation material used in a laboratory furnace?
- Silicon carbide (SiC) is made from quartz sand, petroleum coke (or coal tar), sawdust (green salt produced when adding green silicon carbide) and other raw materials by smelting with resistance furnace at high temperature. Silicon carbide also rare minerals in nature, Mo sangshi. Silicon carbide, also known as carbon silica. Silicon carbide is the most widely used and the most economical kind of refractory materials in C, N, B and other non oxide refractory materials. It can be called "carborundum sand" or "refractory sand".
- Q: What materials are used for roof insulation?
- The other one is inorganic insulation materials, such as Portland, rare earth insulation, the thickness should be 5 cm or more, up to the high cost of auxiliary materials of construction, to reinforce, new inorganic insulation material, the material thickness, on the line of 2-3 cm, direct smear on the top of the house, without auxiliary material, than the price of wool, high aluminum silicate cotton.
- Q: Difference between low creep high alumina brick and ordinary high alumina brick
- The question is good, these two belong to the high aluminum brick products, when many manufacturers buy, I do not know how to distinguish.
- Q: How much is one ton / ton of high alumina refractory brick?
- The price of high alumina refractory bricks is not equal, according to the quality index of GB2988-2012
- Q: What are the specifications for bricks?
- Ordinary brick size of 240 mm * 115 mm * 53 mm, according to compressive strength (Newton / square millimeter, N / mm2) size is divided into MU30, MU25, MU20, MU15, MU10, MU7.5, these intensity levels. Clay brick materials, cheap, durable, and fire prevention, heat insulation, sound insulation, moisture absorption and other advantages, is widely used in civil engineering. Waste brick can also be used as aggregate of concrete. In order to improve the shortcomings of ordinary clay bricks, such as small, self important and waste of soil, they are developing in the direction of light weight, high strength, hollow and big blocks.
- Q: How to test the aluminium bricks of high alumina refractory bricks?
- Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard
- Q: Is glass wool inorganic thermal insulation material?
- Yes, glass wool belongs to one kind of glass fiber. It is a kind of man-made inorganic fiber. Therefore, in the field of thermal insulation materials classified as inorganic insulation materials.
- Q: Does the chimney have high acid resistance?
- If it is an ordinary high alumina brick, it does not meet the requirements of acid resistance, and only the chimney lined with acid resistant bricks.
- Q: How does the physicochemical index change when the high alumina brick is used at high temperature?
- If the range of softening temperature exceeds the load, the constants of other physical and chemical indexes will also increase or decrease.
