Description
Foreliggende oppfinnelse angår en fremgangsmåte for isolering av en byggskillevegg mot fuktighet, hvor skilleveggen tørkes med hjelp av en elektroosmotisk installasjon og hvor hull anordnes eksempelvis ved boring innenfor området av det elektrisk produserte felt, samt at vannavvisende middel innføres i nevnte hull. The present invention relates to a method for insulating a building partition wall against moisture, where the partition wall is dried with the aid of an electroosmotic installation and where holes are arranged, for example by drilling within the area of the electrically produced field, and that a water-repellent agent is introduced into said holes.
Gjennom polsk patentskrift 103 633 er en metode kjent, ifølge hvilken en murtørkingsprosess innledes ved hjelp av en elektroosmotisk installasjon for muravfuktning innenfor et område på fra 1 til 8 %. Videre bores hull innenfor det område der elektrisk feltvirkning oppstår, som hensiktsmessig danner en ca. 35° vinkel mot det horisontale plan. Til hullene til-føres kontinuerlig et hydrofobt middel som også er elektrisk nøytralt. Polene ved den elektroosmotiske installasjonen for-andres deretter til det motsatte. Derved oppnås et undertrykk i kapillærene som følge av en elektroosmotisk væskebevegelse mot den negative pol. Vannavstøtende middel som suges mot murens indre danner derved en blokkering mot fuktighet. Through Polish patent document 103 633 a method is known, according to which a masonry drying process is initiated by means of an electroosmotic installation for masonry dehumidification within a range of from 1 to 8%. Furthermore, holes are drilled within the area where the electric field effect occurs, which appropriately forms an approx. 35° angle to the horizontal plane. A hydrophobic agent which is also electrically neutral is continuously added to the holes. The poles of the electroosmotic installation are then reversed. Thereby, a negative pressure is achieved in the capillaries as a result of an electroosmotic fluid movement towards the negative pole. Water-repellent agent that is sucked into the interior of the wall thereby forms a barrier against moisture.
Ved anvendelse av denne metode utgjør den innledende tørketiden for å oppnå tilstrekkelig avfuktningsgrad, en periode på noen måneder. Dessuten minskes tørkeevnen fordi det eksisterer et permanent elektrisk felt, som polariserer elektrodene og dessuten bidrar til deres korrosjon. De derav ytterligere statiske krefter som oppstår begrenser tydelig gjennomtrengningsområdet for det hydrofobe middel. When using this method, the initial drying time to achieve a sufficient degree of dehumidification is a period of a few months. Furthermore, the drying ability is reduced because a permanent electric field exists, which polarizes the electrodes and also contributes to their corrosion. The resulting additional static forces clearly limit the penetration area of the hydrophobic agent.
Hovedformålet med den foreliggende oppfinnelse er således å frembringe en fremgangsmåte av ovennevnte type som løser ovennevnte problemer. The main purpose of the present invention is thus to produce a method of the above-mentioned type which solves the above-mentioned problems.
Dette mål oppnås med en fremgangsmåte ifølge foreliggende oppfinnelse, som hovedsakelig karakteriseres ved at det for å produsere det elektriske felt, genererer en vekselspenning med en positiv middelverdi over en periode hvor den elektroosmotiske installasjon mates, slik at det elektriske felt oppnås, og at tidspåvirkningen for den positive impuls, hvor tørking og mating av skilleveggen skjer, er 2 This goal is achieved with a method according to the present invention, which is mainly characterized by the fact that, in order to produce the electric field, it generates an alternating voltage with a positive mean value over a period during which the electroosmotic installation is fed, so that the electric field is achieved, and that the time effect for the positive impulse, where drying and feeding of the partition takes place, is 2
til 20 ganger lengre enn for den negative impulspåvirkning, to 20 times longer than for the negative impulse influence,
som innrettes til ikke å understige 20 ms, idet vekselspenningen ordner og dynamiserer vannpartikler, og installasjonselektrodene depolariseres. which is arranged not to fall below 20 ms, as the alternating voltage organizes and dynamizes water particles, and the installation electrodes are depolarized.
En dynamisk og impulsaktig vekselspenningspåvirkning øker tørkehastigheten og tørkeeffekten betydelig (et par ganger), samt gjennomtrengningsområdet for det vannavstøtende middel. A dynamic and impulsive alternating voltage effect significantly increases the drying speed and drying effect (a couple of times), as well as the penetration area of the water repellent.
Fremgangsmåten ifølge oppfinnelsen muliggjør effektiv tørking av porer med svært små og graderte snitt. Takket være denne løsning har også elektrodenes elektrokorrosjon minsket. The method according to the invention enables effective drying of pores with very small and graded sections. Thanks to this solution, the electrodes' electrocorrosion has also decreased.
Formålet med oppfinnelsen forklares nærmere i et eks-empel vist på tegningen, hvor figur 1 viser et skjema for tørkingsinstallasjonen, og figur 2 viser vekselspenningens forløp. The purpose of the invention is explained in more detail in an example shown in the drawing, where figure 1 shows a schematic for the drying installation, and figure 2 shows the course of the alternating voltage.
En elektroosmotisk installasjon er plassert i bygg-veggen 1 mellom jordnivået 2 og bjelkelaget 3. I muren plasseres en rekke elektroder 4 og i jorden nedgraves jord-elektroder 5 i form av et flattjern, en stang eller et rør. Gjennom elektriske kabler i isoleringen 6 fra en tilførsels-anordning 7,tilføres elektrisk energi i form av vekselspenning med en pluss-middelverdi for perioden til elektrodene 4 og 5. Tørkeprosessen fortsettes inntil murfuktigheten er redusert til 10 %. An electroosmotic installation is placed in the building wall 1 between the ground level 2 and the beam layer 3. A number of electrodes 4 are placed in the wall and ground electrodes 5 are buried in the ground in the form of a flat iron, a rod or a pipe. Through electrical cables in the insulation 6 from a supply device 7, electrical energy is supplied in the form of alternating voltage with a plus average value for the period to the electrodes 4 and 5. The drying process is continued until the brick moisture is reduced to 10%.
Mellom elektroden 4 og jordnivået 2 bores hull 8 for vannavvisning med en ca. 30° vinkel mot jordnivå. Disse hull 8 tilføres en vannavvisende væske, f.eks. silikonharpiks. Sam-tidig tilføres elektrodene 4 og 5 vekselspenning med en positiv middelverdi for perioden, hvorved tiden for positiv virkning utgjør ett sekund og for negativ impulspåvirkning 200 ms. Opphold mellom den negative impuls og den etterfølgende positive impuls er også 200 ms. Takket være anvendelsen av elektromating med vekselspenning oppnås ønsket fuktighetsgrad innenfor et tidsrom som er ca. 5 ganger kortere, avhengig av murtykkelse og startfuktighetsgraden. Between the electrode 4 and the ground level 2, a hole 8 is drilled for water repellency with an approx. 30° angle to ground level. These holes 8 are supplied with a water-repellent liquid, e.g. silicone resin. At the same time, the electrodes 4 and 5 are supplied with alternating voltage with a positive mean value for the period, whereby the time for a positive effect amounts to one second and for a negative impulse effect 200 ms. The delay between the negative impulse and the subsequent positive impulse is also 200 ms. Thanks to the use of electrofeeding with alternating voltage, the desired degree of humidity is achieved within a period of approx. 5 times shorter, depending on wall thickness and initial moisture level.
