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:How shall the sintered porous self insulation bricks be laid at the bottom of the beam?
Compared with ordinary bricks, porous brick has the following masonry points: 1. All bricks must be watered before they are built, and no bricks are allowed to be applied to the wall.
Q:What is a JQK composite lightweight thermal insulation brick?
It is a cement based composite waterproof mortar which is pressed and molded. The material has good heat preservation effect and high thermal conductivity.
Q:Which kind of balcony heat preservation material is better?
New inorganic insulation material, this material thickness is thin, in 2-3 centimeters line, direct smear on the top of the house, without auxiliary materials, the price is higher than rock wool, aluminum silicate cotton.
Q:What is the price of thermal insulation brick for exterior wall?
Hello, the exterior wall insulation has many practices, useful insulation bricks, but also useful particles of polystyrene insulation mortar mixed (thickness is not the same, the price is not the same);
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:What's the difference between refractory bricks and insulating bricks?
Insulation brick mainly is used to heat, reduce heat loss, refractory brick is mainly used to withstand flame burn. Bricks usually do not contact fire directly, while refractory bricks usually contact the flame directly.
Q:How to do indoor thermal insulation
Soft packing can also achieve warmth effectTry to change the interior decoration style, whether in visual or make new home warm, in all senses such as the fabric furniture instead of wood or iron rattan furniture, or the use of fabric material packaging wood seat, living room, bedroom stone and tile carpet, lighting equipment can be replaced with warm light lamp. Wall hanging tapestry. When choosing curtain, choose the curtain with thick cloth, thick, insulated and warm effect as much as possible. In addition, the cold tone leather sofa "cotton": a soft warm cotton sofa is the inevitable choice, also can make full use of cotton cushion and pillow.
Q:The project cost in hydropower No.3 shaft wall is solid brick or insulating brick?
Aerated concrete for external walls is to save money. One side is the outer wall.. Solid bricks are the first thing, safety comes first.
Q:Can the whole wall of the high-rise building be made of grey insulation bricks?
If the frame structure, it may be so. What is the length of the whole wall? If it is longer, it is necessary to make a constructional column; if the hole is larger, the edge of the hole needs to be made into a border or a constructional column; if the entrance is small, the edge of the hole is about 300mm and needs solid bricks to build better. South wall thickness can be about 190mm, plus plastering design value of 200mm. Personal comments for reference!
