Abstract

Pulverulent quick-setting binders or torcreting agents which do not evolve dust and have no caustic action. In the building sector such as, for example, in tunnelling or mining, quick-setting binders or torcreting agents are used together with cement and sand or gravel for consolidating rock or loose rock. During processing, these materials evolve dust and thereby lead to caustic effects. To overcome these disadvantages, it is suggested to cause the relevant quick-setting binders or torcreting agents to be absorbed in the liquid form by kieselguhr, whereby dust evolution and hence caustic effects are prevented.

Description

Die vorliegende Erfindung bezieht sich auf die HerstellungThe present invention relates to manufacturing

pulverförmiger Schnellbinder bzw. Torkretierungsmittel, die nicht stauben und nicht sitzend wirken.powdery quick binders or gate locking agents that are not dust and do not appear sitting.

Auf dem Bausektor wie z.B. auch im Tunnelbau oder im Bergbau werden Schnellbinder oder Torkretierungsmittel zusammen mit Zement und Sand oder Kies zum Verfestigen von Gestein oder losem Gestein verwendet. Diese Schnellbinder oder Torkretierunsmittel werdem dem Mörtel oder ton zugemischt als Pulver.In the construction sector such as tunneling or mining Quick binders or gate locking agents together with cement and sand or gravel for the Used to consolidate rock or loose rock. These snap fasteners or gate locks are mixed with the mortar or clay as a powder.

Diese Mittel sind u.a. z.B. Natriumcarbonat, Kaliumcarbonat, Natriumaluminat, Kaliumaluminat, Calciumchlorid, Calciumformiat, Triethanolamin, Amine allgemein oder Gemische aus den genannten Stoffen.These agents include e.g. sodium carbonate, potassium carbonate, sodium aluminate, Potassium aluminate, calcium chloride, calcium formate, triethanolamine, amines in general or mixtures of the substances mentioned.

Der Torkretmörtel wird mit starkem Druck auf den Untergrund gespritzt, dabei tritt eine starke Staubbildung ein. Dabei läßt es sich nicht vermeiden, daß z.B. auoh die hoch alkalischen stoffe wie Natriumcarbonat, Natriumaluminat oder die oben genannten Stoffe mit der haut der Ausführenden in Kontakt geraten. Dies führt bekanntlich oft zu starken Verätzungen.The gate mortar is sprayed onto the substrate with strong pressure, strong dust formation occurs in the process. It cannot be avoided that E.g. also the highly alkaline substances like sodium carbonate, sodium aluminate or the above substances come into contact with the skin of the person performing the work. this as is well known, often leads to severe chemical burns.

Sinn der Erfindung ist, Schnellbinder oder Torkretierungsmittel herzustellen, die nicht staubend oder ätzend wirken.The purpose of the invention is to produce quick fasteners or gate locking means, which are not dusty or corrosive.

Erfindungsgemäß wird dies dadurch gelöst, daß die genannten stoffe als Lösungen auf Kieselgur aufgesprUht werden oder aber in eines Mischer mit Kieselgur vermischt werden. Es können auch die genannten pulverförmigen Stoffe vorher in Wasser gelöst werden und dann eis wässrige Lösung auf kieselgur aufgesprüht werden oder in einem Mischer mit Kieselgur vermischt werden.According to the invention this is achieved in that the substances mentioned be sprayed onto diatomaceous earth as solutions or in a mixer with diatomaceous earth be mixed. You can also use the powdered substances mentioned beforehand water are dissolved and then ice-water solution can be sprayed onto kieselguhr or be mixed in a mixer with kieselguhr.

Die in dieser Weise hergestellten Schnellbinder oder Torkretierungsmittel stauben bei der Verarbeitung nicht und wirken auch nicht ätzend.The quick-release fasteners or gate-locking means produced in this way do not generate dust during processing and are also not corrosive.
