Description
Verfahren zur Verkittung mehrteiliger Leitungs-Isolatoren. Nach einem bekannten Verfahren zur Verkittung mehrteiliger Leitungs-.Isolatoren werden als Kittmasse hydraulisch abbindende Stoffe, wie z. B. Portlandzement, benutzt, welche mit fein gepulverten Schmelzkörpern, wie Harzen, Pechen, Asphalten, Schwefel u. d-1., gemischt und nach dem Hartwerden des Zements so weit erwärmt, daß die Schmelzkörper die Poren der Zementmasse ausfüllen. Dem Gemisch können sonstige pulverige oder faserige Massen beigefügt werden, wie Asbest, Quarzmehl o. dgl.Method for cementing multi-part line insulators. After a known methods for cementing multi-part line .Isolators are called Putty mass hydraulically setting substances, such as. B. Portland cement, which with finely powdered melting bodies, such as resins, pitches, asphalt, sulfur and the like. d-1., mixed and, after the cement has hardened, heated so far that the enamel bodies fill the pores of the cement paste. Other powdery or fibrous masses are added, such as asbestos, quartz powder, or the like.
Der Gegenstand der vorliegenden Erfindung bezweckt nun, eine Verbesserung des obengenannten Verfahrens herbeizuführen.The object of the present invention now aims at an improvement to bring about the above procedure.
Während bei dem bekannten Verfahren der Schmelzprozeß bisher so vorgenommen wurde, wie man es z. B. handwerksmäßig bei der Anfertigung von Bausteinen gewöhnt war, verfährt man im vorliegenden Falle anders.While in the known method, the melting process has so far been carried out in this way was how to do it z. B. used to craftsmanship in the manufacture of blocks was, one proceeds differently in the present case.
Durch die bisher wahllose Trocknung und Verschmelzung gelangt man nämlich nicht zu einem homogenen Kitt, was aber im Hinblick auf die Eigenart der erforderlichen Kittmasse die Voraussetzung für die gewünschte Wirkung ist. Die Trocknung und Verschmelzung des in der Erhärtung begriffenen Zements im ungeeigneten Zeitpunkt bewirkt Feuchtigkeitsnester, Blasenbildungen, erhebliche Unregelmäßigkeiten in der chemischen Struktur und eine unsichere Unterbindung der molekularen Weiterbetätigung des hydraulisch erstarrenden Körpers. Diese Mängel sind einem Baustoff schon schädlich, vielmehr noch einem Kitt, wie er hier benötigt wird. Die äußere Kittschicht wird durch eine zu unzweckmäßiger Zeit erfolgende Erwärmung verklebt, infolgedessen hat die innere Feuchtigkeit keine Gelegenheit, zu entweichen.One gets through the hitherto indiscriminate drying and fusing namely not to a homogeneous putty, but what with regard to the peculiarity of the required putty is the prerequisite for the desired effect. The drying and fusion of the hardening cement at the unsuitable time causes moisture pockets, blistering, considerable irregularities in the chemical structure and an unsafe prevention of further molecular activity of the hydraulically solidifying body. These defects are already harmful to a building material, rather, a putty, as it is needed here. The outer layer of putty will stuck by too inexpedient time taking place heating, as a result the internal moisture does not have an opportunity to escape.
Um daher die aufgezählten Schäden zu vermeiden, geht man jetzt bei der Trocknung stufenweise fortschreitend vor und wendet zunächst zur Verdunstung der im abgebundenen Kitt verhandenen Feuchtigkeit niedere Temperaturen an. Dabei ist als wichtiger Umstand und neuer Gesichtspunkt zu beachten, daß die Trockentemperatur nicht den Schmelzpunkt des Bindemittels erreichen darf, ehe alles Wasser .aus dem erhärteten Kitt verdunstet ist, also denjenigen Wärmegrad, wo die Schmelzkörper aus dem festen oder dem Erweichungszustand in die Leichtflüssigkeit übergehen. Vorteilhaft kann man auch mit Luftleere arbeiten.In order to avoid the damage listed, one goes to now the drying progresses step by step and turns first to evaporation the moisture present in the set putty indicates lower temperatures. Included It is important to note that the drying temperature must not reach the melting point of the binder before all the water .from the hardened putty has evaporated, i.e. the degree of heat where the melting body pass from the solid or the softened state into the light liquid. Advantageous you can also work with a vacuum.
Nach dem neuen Verfahren wird ermöglicht, daß sich die Feuchtigkeit aus den tiefsten Stellen der Steinmasse entfernen läßt, ehe ein Flüssigwerden des Bindemittels eintritt. Dieser Prozeß geht selbst bei starken Schichten sehr leicht vor sich, da hart gewordener Zement, in welchem die Schmelzkörper noch nicht flüssig sind, sehr porös und durchlässig ist.According to the new process, the moisture is made possible can be removed from the deepest parts of the stone mass before the Binder occurs. This process is very easy even with thick layers in front of him there is cement that has hardened, in which the enamel bodies are not yet liquid are very porous and permeable.
Der Schm-elzprozeß darf daher in allen Schichten des Kitts zu gleicher Zeit erst dann erfolgen, nachdem durch die Poren des erhärteten Zements die Wasserreste entwichen sind. Durch die Erwärmung hat eine beschleunigte Hydratation des hydraulischen Mittels, z. B. des Portlandzements, stattgefunden. Jetzt beginnt bei ansteigender Temperatur die Durchdringung des Steingerippes mit dem schmelzenden Asphalt, und das Ausfüllen der Poren vollzieht sich quantitativ.The melting process may therefore be the same in all layers of the cement Time only takes place after the water residue has passed through the pores of the hardened cement have escaped. Due to the warming has an accelerated hydration of the hydraulic By means of e.g. B. Portland cement took place. Now starts with increasing Temperature the penetration of the stone ribs with the melting one Asphalt, and the pores are filled quantitatively.
Als Ergebnis dieser Verschmelzung nach obigem Verfahren entsteht dann ein völlig gleichmäßiger Kitt, der keine schädlichen Schichtungen mehr besitzt.As a result of this amalgamation according to the above method then arises a completely uniform putty that no longer has any harmful layers.
