Description
523 705 Z. kvarhålla samma arbetsbarhet med ett lägre eller lika lågt vattencementtal som utan tillsatsen av kolloidal silika. Kolloidal silika fungera förutom som ett pozzolansk material också som ett fint fyllnadsmaterial och bildar en kompakt stampmassa med tät struktur. Detta leder till att ångtryck som byggs upp vid höga temperaturer kommer att orsaka en explosiv avflisning. Stampmassan blir därmed känslig för temperaturvariationer. Den ökade motståndskraften mot temperaturförändringar förbättras genom att man använder ett luftporbildande tillsatsmedel. Detta skapar fler problem än det löser. Vilken typ av ballast som används är också viktigt. Ballasten måste tåla de höga temperaturer som råder i skorstenen. 523 705 Z. maintain the same workability with a lower or as low water cement number as without the addition of colloidal silica. In addition to being a pozzolanic material, colloidal silica also acts as a fine filling material and forms a compact stamping compound with a dense structure. This leads to vapor pressure that builds up at high temperatures will cause an explosive chipping. The stamping mass thus becomes sensitive to temperature variations. The increased resistance to temperature changes is improved by using an air pore-forming additive. This creates more problems than it solves. The type of ballast used is also important. The ballast must withstand the high temperatures prevailing in the chimney.
Förutom valet av material så är blandningsförfarandet ytterst viktigt Ordningen i vilken man blandar de olika komponentema och blandningstiden spelar en avgörande roll på stampmassans egenskaper, eftersom detta styr möjligheterna till sammanstötning av de kemiska tillsatserna och spridningen av bindemedlen.In addition to the choice of material, the mixing process is extremely important. The order in which the different components are mixed and the mixing time play a decisive role in the properties of the pulp, as this controls the possibilities of collision of the chemical additives and the spread of the binders.
Beskrivning av uppfinningen Det är nu möjligt att tillverka en stampmassa enligt denna uppfinningen som löser de ovan nämnda problemen. Uppfinning kännetecknas av att den innefattar en eller flera sorters portlandcement och kolloidal silika, en eller flera sorters sand och pirnsten, och kemiska tillsatser i form av sulfonatiserat naftalenformaldehydkondensat eller sulfonatiserat melaminformaldehydkondensat.Description of the invention It is now possible to manufacture a stamping compound according to this invention which solves the above-mentioned problems. The invention is characterized in that it comprises one or more kinds of Portland cement and colloidal silica, one or more kinds of sand and pumice, and chemical additives in the form of sulfonated naphthalene formaldehyde condensate or sulfonated melamine formaldehyde condensate.
Ytterligare egenskaper kommer att framgå av de medföljande patentkraven. Denna uppfinning innefattar också ett förfarande för tillverkning av en sådan stampmassa, som karaktäriseras enligt ovan.Additional features will be apparent from the appended claims. This invention also includes a method of making such a stamping composition, which is characterized as above.
Med hjälp av denna uppfinning löses de ovan nämnda problemen och en stampmassa med god vidhäftningsförmåga, nötningsbeständighet-och temperaturförändringsresistens erhölls.By means of this invention the above-mentioned problems are solved and a stamping compound with good adhesiveness, abrasion resistance and temperature change resistance was obtained.
Uppfinningen kommer att beskrivas närmare i det följande med hänvisning till en exemplifierande utföringsform utan att för den skulle vara begränsad till detta.The invention will be described in more detail in the following with reference to an exemplary embodiment without it being limited thereto.
Exempel Olika proportioner av kolloidal silika blandades med portlandcement som försetts med olika mängder sand och pimsten. Vatten tillsattes sedan långsamt och försiktigt under blandningen fick en blöt yta.Examples Different proportions of colloidal silica were mixed with Portland cement provided with different amounts of sand and pumice. Water was then added slowly and carefully during mixing to a wet surface.
Vattenreducerande medel tillsattes med en liten mängd vatten och blandades. Till slut tillsattes en luftporbildaren med den resterande mängden vattnen och blandades under ytterligare 2 minuter.Water reducing agent was added with a small amount of water and mixed. Finally, an air pore former was added with the remaining amount of water and mixed for another 2 minutes.
Den stampmassa som då tillverkades visade sig ha bra vidhäftning till tegel, både nytt och gammalt. Det hade även bra resistens mot temperaturförändringar och nötning.The stamping compound that was then manufactured proved to have good adhesion to bricks, both new and old. It also had good resistance to temperature changes and abrasion.
Stampmassaan applicerades på tegel med en murslev och "tänjdes" därmed ut. N är det studerades under mikroskop farm man inga sprickor.The stamping mass was applied to bricks with a trowel and thus "stretched" out. N is it was studied under a microscope farm no cracks.
Efter att tegelstenania blivit förvarade i rumstemperatur och blivit upphettade till 1000°C i en elektrisk ugn gjorde man följande observationer: Inga sprickor kunde observeras. Materialet anslöt tätt till tegel även efter upphetningen. Materialet visade god vidhäftning och kompatibilitet till tegel.After the bricks were stored at room temperature and heated to 1000 ° C in an electric furnace, the following observations were made: No cracks could be observed. The material adhered tightly to brick even after heating. The material showed good adhesion and compatibility with bricks.
*S23 705 3 Blandningarna testades även i nykonstruerade skorstenar där temperaturen höjdes till 1000°C under 8 minuter. Det observerades att tegelinklädningen var tät och hade bra isoleringsegenskaper eftersom temperaturen på utsidan av skorstenarna var låg. Inga sprickor kunde observeras på utsidan av murverket eller på insidan av skorsten när man använde en högtemperaturkamera. Efter att skorsten fått svalna av borstades den med en hård borste och mycket lite material föll då av. Testen genomfördes enligt kraven för tester på stampmassor i skorstenar hos Danmarks Brandinstitut, och materialet klarade av alla nödvändiga krav.* S23 705 3 The mixtures were also tested in newly constructed chimneys where the temperature was raised to 1000 ° C for 8 minutes. It was observed that the brick cladding was tight and had good insulation properties because the temperature on the outside of the chimneys was low. No cracks could be observed on the outside of the masonry or on the inside of the chimney when using a high temperature camera. After the chimney was allowed to cool, it was brushed with a hard brush and very little material fell off. The test was carried out in accordance with the requirements for tests on stamping compounds in chimneys at the Danish Fire Institute, and the material met all the necessary requirements.
Det har visat sig att man kan använda följande proportioner av de olika ingredienserna: Portlancement 20-25% av totalvikten, Vikt% Kolloidal silika 2.5-5% av totalvikten, Vikt % Sand 70-75% av totalvikten, Vikt% Pimstenballast 5-10% av totalvikten, Vikt% Vattenreducerandemedel 2-3.5% av cementvikten, Vikt% Luftpobildare 0.1-0.2% av cementvikten, Vikt% Vattenbindemedeltal 04-045 Luftporbildaren som användes är en naturlig produkt baserad på ett protein.It has been found that the following proportions of the various ingredients can be used: Portlancement 20-25% of the total weight, Weight% Colloidal silica 2.5-5% of the total weight, Weight% Sand 70-75% of the total weight, Weight% Pumice ballast 5-10 % of total weight, Weight% Water reducing agent 2-3.5% of cement weight, Weight% Air pore former 0.1-0.2% of cement weight, Weight% Water binder average 04-045 The air pore former used is a natural product based on a protein.
Vattenreducerande medel som användes är sulfonafiserat naftaleneformeldehydkondensat och sulfonaiiserat melaminformaldehykondensat.Water reducing agents used are sulfonated naphthalene formaldehyde condensate and sulfonated melamine formaldehyde condensate.
Demia uppfinning innefattar även skorstenar inkläda med inklädningsmaterial från denna uppfinning.This invention also includes chimneys lined with cladding materials of this invention.
