Q:What is the difference between the production line of foamed cement insulation bricks and the self thermal insulation block production line?
Yes, this year's business is not very good to do, customers pay more attention to the quality of products, seven industrial equipment, very satisfied with the service OK
Q:What kind of material is clay insulation refractory brick made of?
According to the different origin of general clay brick raw materials are not the same with Henan or Hebei with perlite beads, pyrojewel, use effect and technology of Henan is better than Hebei
Q:Are there any special requirements for the use of raw materials in thermal insulation brick production equipment? What about the raw materials?
Specific funding, different production, different raw materials configuration will be different. According to the design requirements, refining production process, for production process, production management level, complete monitoring, pulping system on the lower computer, based on control level; lower machine by the programmable controller (PLC) is mainly composed of a crushing system. The host computer takes the standard industrial control computer (IPC) as the main man-machine interface (HMI) and beating system, and if possible, it is recommended to investigate on site
Q:Can fly ash brick keep warm?
Add blocks and have autoclaved fly ash bricks, do not you?
Q:Is it necessary to abolish the technical regulations for the construction of self thermal insulation masonry building with sludge sintering insulation bricks?
Silt sintering brick insulation brick is made from river mud, city sludge, mud as the main raw materials, added according to a certain proportion of siliceous inorganic binder after aging, extrusion blank, blank by cutting, drying, sintering and extrusion molding machine. The utility model has the advantages of energy saving, resource saving, favorable for developing circular economy and comprehensive utilization of resources, high micropore rate, good product heat insulation performance and heat insulation performance, etc..
Q:What are the insulation materials for heating buried pipelines?
The thickness of insulation layer should be reasonable and economical. If the insulation layer is too thin, the heat loss will be increased; the insulation layer is too thick, and the surface area of the radiator will be increased, and the heat loss will also be increased. In general the design, determine the thickness of the insulation layer according to the factors of insulation material properties, heat medium temperature, often used for 40~50 mm thickness.
Q:Why does the water drop first and then rise when the boiler fires?
This is the reason for the zero water level gauge line below the center line of the drum. Under normal conditions for water and evaporation is balanced, after the fire, reduce the amount of steam water mixture into the drum in the evaporation decreased rapidly, reduce the volume of water bubbles, sudden contraction, drum water level decreased rapidly. But not to water change or increase (automatic), water balance is broken, the water level will rise rapidly.
Q:Energy saving bricks or bricks?
Insulating bricks are mostly hollow or light bricks.It can be said to be energy-saving bricks, including insulation bricks
Q:Are there any differences between insulating bricks and refractory bricks
The insulation performance of thermal conductivity of insulating brick in general 0.2-0.4 (average temperature 350 - 25 DEG C) w/m.k, and the thermal conductivity of refractory brick in 1 (the average temperature of 350 - 25 DEG C) above w/m.k, which can obtain the insulation performance of insulating brick than refractory brick insulation performance is much better.
Q:What are the new types of building brick materials?
In addition to the original clay brick, other masonry materials seem to be called new materials. Sintered silt bricks, steam blocks, lightweight blocks, hollow clay bricks, etc..
