Abstract

Where buildings may contain asbestos and are thus potentially hazardous, a special liq. is sprayed into the building. The liq. is pre-treated to give it an electrostatic charge and a drying period of 1-6 hours is then observed. The liq. is water based with protein cpd. addns. and is formed into a mist of particles, 10 power (-5) - 10 power (-6) in size. ADVANTAGE - Makes buildings safe before removal of asbestos

Description

Seit Jahren werden Versuche unternommen, die hauptsächlich in öffentlichen Gebäuden eingebauten Feuerschutzmaßnahmen mit Beimischung oder auch freien Asbestmaterialien verbundenen Gesundheitsgefährdungen zu beseitigen oder zu mindern.Attempts have been made for years, mainly in fire protection measures installed in public buildings Admixture or free asbestos-related health hazards to eliminate or mitigate.

Man hat insbesondere in Schulen die Asbestbauteile herausgerissen, sie in Plastikmaterialien eingeschweißt und in der Regel auf Deponien entsorgt. Andererseits hat man nach Ausbau dieser Baubestandteile die Asbestplatten, Steine und Baumischungen durch Einsprühen mit Bindestoffen bearbeitet und dann noch in Plastikunterlagen entsorgt. Die Deponien werden aber auch in der Regel mit anderen, unerwünschten Materialien belastet und von Zeit zu Zeit durch Bagger u. ä. Bewegungsgeräte verschoben, umgeschichtet usw. Dabei können natürlich auch Plastiksäcke aufgerissen werden und somit wieder die Asbestgefahr entstehen lassen.The asbestos components have been torn out, especially in schools, they are welded in plastic materials and in the Usually disposed of in landfills. On the other hand, after expansion of these components include the asbestos slabs, stones and building mixes processed by spraying with binding agents and then disposed of in plastic documents. The landfills will but also usually with other, undesirable materials burdened and from time to time by excavators u. Ä. Movement equipment shifted, shifted, etc. Of course you can also plastic bags are torn open and thus the Allow asbestos to develop.

Mit dem Abriß von Gebäuden oder dem Herausnehmen von Bauteilen sind sehr hohe Kosten verbunden, die insbesondere beim Schutz der Menschen während des Abreißens entstehen. Ganze Teile der Gebäude müssen luftdicht abgeschottet werden, um die Atemluft durch Umwälzen und -filtern ständig in Bewegung zu halten. Auch hier wurden Versuche unternommen durch Besprühen der Bauteile, um die als besonders gefährlich bekannten Asbestfasern zu fixieren. Als Fixiermittel werden verschiedenste Materialien benutzt, insbesondere Kunststoffe mit Lösungsmitteln u. ä.With the demolition of buildings or the removal of components are associated with very high costs, especially when it comes to protection of people arise during the demolition. Whole parts of the Buildings must be hermetically sealed to keep breathing air  keep moving by circulating and filtering. Also attempts were made here by spraying the components, around the asbestos fibers known to be particularly dangerous fix. Various materials are used as fixatives used, especially plastics with solvents and. Ä.

Erfindungsgemäß wurde nun festgestellt, daß man in der Regel die Gebäude nicht abzureißen braucht, wenn man die im Bau befindlichen Asbestfasern so fixiert, daß auch die kleinsten Ritzen verschlossen werden, um sie praktisch bis zur endgültigen Vernichtung der Gebäude nach Jahrzehnten festzuliegen.According to the invention, it has now been found that, as a rule there is no need to demolish the buildings if you are building them Asbestos fibers are fixed so that even the smallest Chinks are sealed to make them practically to the final To destroy the buildings after decades.

Zweckmäßigerweise soll aber in bestimmten Zeitabläufen eine Nacherprobung durchgeführt werden, um festzustellen, ob sich irgendwo diese Fixierung gelöst hat.However, one should expediently be used in certain time sequences Follow-up tests will be carried out to determine whether somewhere has loosened this fixation.

Da es falsch wäre, diese schädliche Substanz mit einer anderen schädlichen Substanz zu bekämpfen, wurden die Erprobungen von vornherein auf das Thema "Wasserlösliche Materialien" festgelegt.Since it would be wrong to use this harmful substance with another The trials were to combat harmful substance fixed from the start on the topic of "water-soluble materials".

Um eine Fixierung und eine Tiefenwirkung zu erreichen, ist es notwendig, diesem Wasser spezielle Eiweißverbindungen beizufügen. Eine weitere, notwendige Wirkkomponente besteht aus Nebel mit der Größenordnung von 10-5 bis 10-6, der durch eine besondere Verarbeitungslinie elektrostatisch so aufgeladen wird, daß er sich überall dort einnistet, wo eine entsprechende Möglichkeit besteht.In order to achieve a fixation and a deep effect, it is necessary to add special protein compounds to this water. Another, necessary active component consists of fog with the order of 10 -5 to 10 -6 , which is electrostatically charged by a special processing line in such a way that it nests wherever there is a corresponding possibility.
