My home security windows installed when the wall is found in the insulation layer, the expansion of the bolt into the wall after they have pulled out, fixed, how can we make the expansion bolt into the wall insulation layer touch whip sniper Biao riveting riveting fixed and stuffed into the brick wall to fix the effect as well.

To do the top of the hired to hire people who overlooking the Beijing wall roof insulation construction, then use the adhesive, is a dry mortar, add water after use. Sticky benzene board and extruded board are used in adhesives, adhesive extrusion board with a slightly higher adhesive requirements (that is, the amount of additives used in the production of different)
From the process it To overcome the EPS board complex production process, with EPS board can not replace the superior performance. It is made of polystyrene resin and other additives through the extrusion process has a continuous uniform surface and closed-cell honeycomb structure of the plate, the honeycomb structure of the thick plate, there is no gap, this closed-cell structure Insulation materials can have different pressures (150-500Kpa) at the same time have the same low value of the thermal conductivity (only 0.028W / MK) and enduring excellent insulation and compression performance, compressive strength up to 220-500Kpa.
Sticky benzene board and extruded board are used in adhesives. . bonding (bonding, bonding, bonding, adhesive) refers to the surface of homogeneous or heterogeneous objects with adhesives connected together with the technology, with a continuous stress distribution, light weight, or sealed, the majority of low temperature technology The Adhesive is particularly suitable for different materials, different thickness, ultra-thin specifications and the connection of complex components. Glue the rapid development of modern times, the application industry is very wide, and high and new scientific and technological progress and people's daily life has a significant impact. Therefore, research, development and production of various types of adhesives is very important. . extruded board refers to the polystyrene foam is divided into expansive EPS and continuous extrusion XPS two, compared with the EPS sheet, XPS board is the third generation of rigid foam insulation material
Really embarrassed, it is impossible to change. There are two air-conditioning heating and cooling machine: one is the use of the opposite compressor operation, the outside of the heat discharged to the room. The second is on the basis of the first plus a shop to help heating, (rather than heating wire heating), but the heating wire heating is when the ambient temperature is too cold, air conditioning can not run when the start. So if you want to add a single cold in the cold outside the compressor, but the most important parts of air conditioning is the compressor, it is impossible to change, no one will do, even if it is changed, that the indoor unit is not necessarily able to use , Like a computer, pay attention to the preparation, preparation is different from the problem.
