Description

450 264 En dynamisk och impulsaktig växelspänningsverkan ökar avsevärt (ett par gånger) torkningshastigheten och tork- ningseffekten samt ökar även penetrationsomràdet för det vatten- avvisande medlet. 450 264 A dynamic and impulse-like AC action significantly increases (a couple of times) the drying speed and the drying effect and also increases the penetration range of the water-repellent agent.

Förfarandet enligt uppfinningen möjliggör effektiv torkning av porer med mycket små och graderade förekommande snitt.The method according to the invention enables efficient drying of pores with very small and graded incisions.

Tack vare denna lösning har även elektrodernas elektrokorrosion minskat.Thanks to this solution, the electro-corrosion of the electrodes has also been reduced.

Föremálet för denna uppfinning belyses närmare i ett exempel med hjälp av bifogade ritningsillustration, i vilken fig. l visar schema för torkningsinstallationen, och fig. 2 visar växelspänningsförloppet.The object of this invention is further illustrated in an example by means of the accompanying drawing illustration, in which Fig. 1 shows a diagram of the drying installation, and Fig. 2 shows the alternating voltage course.

Elektroosmotisk installation är placerad i bygg- väggen 1 mellan marknivàn 2 och bjälklaget 3. I muren placeras en rad av elektroder 4 och i jorden grävs jordelektroder 5, i form av ett plattjärn, en stång eller ett rör, ned. Genom elektriska kablar i isoleringen 6 fràn en matningsanordning 7 tillföres elektrisk energi i form av växelspänning med ett plusmellanvärde för perioden till elektroderna 4 och 5. Torkningsprocessen fort- går tills murfuktigheten minskat till 10%.Electroosmotic installation is located in the building wall 1 between the ground level 2 and the floor 3. A row of electrodes 4 is placed in the wall and earth electrodes 5, in the form of a flat iron, a bar or a pipe, are buried in the ground. Electrical cables in the insulation 6 from a supply device 7 supply electrical energy in the form of alternating voltage with a positive intermediate value for the period to the electrodes 4 and 5. The drying process continues until the wall humidity has decreased to 10%.

Mellan elektroden 4 och markniván 2 borras hàl 8 för vattenavvisning med ca 300 vinkel mot markplanytan. Till dessa hål 8 tillföres en hydrofob (vattenavvisande) vätska, för- slagsvis silikonkåda. Samtidigt matas elektroderna 4 och 5 med växelspänning med ett positivt medelvärde för perioden, varvid tiden för positiv verkan utgör l sekund och för negativ impuls- verkan 200 ms. Uppehállet mellan den negativa impulsen och den efterföljande positiva impulsen är också 200 ms. Tack vare an- vändningen av elektrodmatning med en växelspänning har erforder- lig fuktighetsgrad uppnåtts inom en tidsrymd, som är cirka 5 gånger kortare beroende av murtjocklek och den inledande fuktig- hetsgraden. 3%'Between the electrode 4 and the ground level 2, a hole 8 is drilled for water repellency with approximately 300 angles to the ground plane surface. A hydrophobic (water-repellent) liquid, preferably silicone resin, is supplied to these holes 8. At the same time, the electrodes 4 and 5 are supplied with alternating voltage with a positive average value for the period, the time for positive action being 1 second and for negative impulse effect 200 ms. The interval between the negative pulse and the subsequent positive pulse is also 200 ms. Thanks to the use of electrode supply with an alternating voltage, the required degree of humidity has been achieved within a period of time, which is approximately 5 times shorter depending on the wall thickness and the initial degree of humidity. 3% '
