Many people who, due to the duty of their profession, or privately, are faced with construction, are well aware of what ICBMs are. But the thing is that to date , civil engineers have not figured out how to replace the bitumen-rubber composition. It is used in the construction of roofs, for the processing of which mastic is used, as well as when using rolled materials for roofing.
So,
bitumen mastic ICBM 65 was certified back in Soviet times. But this does not mean that since then its composition has not changed and has not been modified. There are two varieties of it - liquid and thick. In itself, it represents petroleum bitumen with additives of filler and plasticizer. The latter, in turn, gives it viscous properties, which makes it easy to apply the solution to the roof surface.
Composition and structure
Due to its composition, bitumen-rubber mastic (ICBM) quickly combines with any materials. Therefore, its packaging is made in special release containers or bags. To give the substance the necessary plasticity, rubber crumb is added to it.
Where is it used?
On all multi-story buildings today, a mastic-based roof is laid. Its advantage is that it completely fills all available gaps with itself. Work with mastic is done, pre-heating it. Those who are aware of what ICBMs take into account this fact, so they are warmed up in advance. It softens completely at a temperature of about 90 ° C.
Before starting work, the surface is prepared. To do this, the roof is cleaned of existing debris. Also, before starting work on the
roof, the roof is dried. In this case, special gas burners are used. If the weather is dry and hot, this procedure can be omitted.
Application features
In addition to the above methods of application, those who know what an ICBM is, use it also when laying pipelines. The fact is that ICBM 65 has a higher softening temperature and therefore is used to isolate structures that are constantly exposed to vibration. In the process of mechanical deformation of the processed pipe, the mastic layer will change with it.
Varieties
Now, having understood what ICBMs are, we will consider some of its common varieties.
Mastic MBR-100 is used when laying rolled materials for roofing, as well as for pouring waterproofing screeds. The number indicated on its marking indicates the temperature at which softening occurs. But at the same time, it is worth considering that it is necessary to heat up the mastic to 200 ° C. All this is done in order to easily apply it on pitched surfaces, as well as on vertically located walls.
Anyone who has long figured out what bitumen mastic is , has at least once encountered such a variety as MBR-X. A feature of this material is that for its use, preheating is not required. This is achieved due to the fact that the composition includes a special solvent, which after application evaporates spontaneously, and the mastic freezes.
