Q:What is the price of concrete self insulation bricks
If you really want to buy thermal insulation brick, do not simply look at the price, but also to consider the quality of the product. (a piece of brick in the market basically in 6 yuan, if there is a floating price if it is because of the size of the insulation brick or distance, but floating slightly.)
Q:Why does the water drop first and then rise when the boiler fires?
Often in the operation of the boiler, the steam water mixture to the drum after intense evaporation of a large number of bubbles in the water side, the water volume expansion. By actual water level drum water level indicator is higher than the water level
Q:What are the new types of building brick materials?
The whole material made of brick and mortar is one of the most widely used building materials. According to whether the masonry is reinforced, it is divided into unreinforced brick masonry and reinforced brick masonry.
Q:What is the maximum temperature range of high temperature resistant insulation materials?
A class of inorganic non-metallic materials with a refractoriness of not less than 1580 degrees. Refractoriness is defined as the temperature of a sample of a refractory cone sample that resists high temperature without loading and does not soften and melt down. But only in terms of fire resistance can not be fully described refractories, 1580 degrees of temperature is not absolute.
Q:How to do indoor thermal insulation
Basic decoration, can make indoor insulation work, such as some specific practices: when laid wood floor, the grille can be in the floor of the placement of insulation materials, such as mineral wool board, flame retardant foam etc.. In the custom doors, may require manufacturers with glass wool or mineral wool insulation materials etc.. To install windows and doors are sealed, if the window is the original single ordinary window glass, then the best decoration for hollow glass broken metal windows, can also use light decoration patent products: multifunctional solar heating refrigeration air conditioning doors and windows, doors and windows. Live in the top floor of the residents, but also in the ceiling when placed on the gypsum board insulation materials, in order to improve insulation. If the original wall has internal insulation layer, be careful not to destroy when decorating. If the design is to open the balcony and living room, it is necessary to install the insulation layer on the wall and top surface of the balcony.
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:Is the quality of brick made of small-sized self insulation block equipment the same as that of large block brick equipment?
Recently, a lot of people have encountered this problem, Silver Horse understand, in fact, the brick machine is only the production of different production, the quality of the bricks produced are the same.
Q:What are the improvements and improvements during the trial production of insulating bricks?
Insulation brick seven characteristics: insulation, heat insulation: effectively reduce energy consumption.Fire prevention: up to national standard or class A.Clean and environmental protection: no two pollution will be caused by air.
Q:Difference between inorganic insulation material and organic thermal insulation material
The main difference between inorganic insulation materials and organic thermal insulation materials is that the types of insulation materials are different:1, inorganic insulation materials, including glass wool, rock wool, expansion perlite, micro nano insulation board;2, organic insulation materials are mainly polyurethane foam, polystyrene board, phenolic foam and so on.
Q:What are the sizes of lightweight thermal insulation bricks?
The production of material ordinary lightweight insulating refractory brick with fireclay and high alumina high strength bead brick
