Definitions
- the invention is concerned with a production method a vapor and moisture barrier in ceramic chimney flue pipes and appropriately treated flue pipes.
- Liquid and vapor condensate travels through the porous capillary structure of ceramic smoke pipes to the outside and occurs on the outside of the flue as moisture on, which must be eliminated by various measures. So it is known for three-shell fireplaces in which the Smoke pipe is surrounded by a thermal barrier coating, To provide ventilation channels in the thermal insulation layer in order to penetration of moisture into the thermal insulation layer prevent. Often are on the chimney base on the outside of the Flue pipe collecting trays or the like for receiving external condensate provided. Another known measure is in ceramic smoke pipes from the outset a barrier against the passage of Build up steam and moisture from the flue gas.
- the present invention is concerned with such Process for creating a moisture barrier in ceramic smoke pipes, taking her task lies in making the process simple and the Effectiveness of the moisture barrier in terms of temperature and to expand considerably in time.
- inorganic-organic hybrid polymers Compounds considered to be a molecular or nanostructured Base material with inorganic and have organic elements (cf. "First European Workshop, on Hybrid Organic-Inorganic Materials - Center National de la Recherche Scientifique,le de Bierville, 8-10 November 1993).
- Such hybrid polymers are known under the brand name ORMOCER of the Fraunhofer Institute for silicate ISC, Würzburg or by the company nanogate GmbH, Saar Hampshire. They are manufactured Hybrid polymers mainly through hydrolysis and condensation of silicic acid esters and metal alcoholates as Basic materials. These are given special properties Systems through the installation of organically modified Silicic acid derivatives in the silicate network. Thereby desired properties can be set and also the organic parts cause the structure an organic polymer network.
- the hybrid polymers can be in water or solvents be dispersed or dissolved so that the application on the surface to be treated with the usual Coating techniques such as dipping, spinning, pouring or Spraying is possible. Connects to the order process is a drying or hardening process that by thermal treatment or with the help of UV or Heat radiation is feasible. Depending on the type of determination Hybrid polymers can use thermal treatment and drying between room temperature and 400 ° C.
- the particles making up the hybrid polymers are one size have in the nano range and therefore in the ceramic Capillary structures lighter and deeper than polysiloxanes can penetrate, it is correspondingly sufficient Exposure time of the one or more hybrid polymers contained liquid possible, the hybrid polymers as Moisture barrier not only as a layer on the Smoke pipe surface, but also over several millimeters deep in the near-surface capillary structure. This can clog the pores of the capillary structure so that the one under the surface Moisture barrier remains effective even when the hybrid polymer layer on the surface should be damaged.
- fluorosilanes are also used.
- fluorosilanes fluoroalkyl functional silanes into consideration with water with hydrolysis and cleavage of ethanol to one reactive silanol react, the silanol chemically an inorganic substrate can be bound.
- an Si-O bond is formed on the surface. That there is a cross-linking with formation of a Siloxane network.
- the fluorosilanes are extraordinary thin layers in the nanometer range Pore openings of the capillary structure of the ceramic Surface and on the free surfaces of the capillary structure built up near the surface inside the ceramic body become.
- Fluorosilanes of the type described are commercially available under the Brand names DYNASYLAN F 8261 (in variations thereof under F 8262 and F 8263) from Sivento Chemie GmbH, Düsseldorf, available.
- the fluorosilanes can with water and solvents, such. B. Ethanol, mixed so that application to the treating surface with the usual Coating techniques such as dipping, spraying, painting or Polishing is possible. This is followed by the order process a drying or crosslinking process by thermal treatment or with the help of UV or Heat radiation is feasible.
- the thermal treatment can be carried out between 80 and 150 ° C.
- Cheaper is however a baking process at temperatures up to 600 ° C, because it has been shown that this does not affect the weight falling decrease in the fluorosilane hydrophobic property a significant increase in mechanical resilience, such as abrasion resistance, with goes along.
- the described hybrid polymers and fluorosilanes hold Temperatures up to 600 ° C, d. H. Temperatures that at least with house chimneys not or rarely be crossed, be exceeded, be passed.
- the hybrid polymers and fluorosilanes used in the process according to the invention exhibit a high mechanical resistance and adhesive strength on the ceramic surface of the smoke tube. This is apparently due to the fact that components of the silicate network of these compounds bind to SiO 2 residues of the smoke tube ceramic material, which leads to the considerable adhesive strength.
- the hybrid polymers can also be designed by the incorporation of groups or radicals which increase the surface energy in such a way that the adhesion of mortar and adhesive as connecting materials is not impaired but rather promoted.
- the known hydrophobic behavior of the hybrid polymers and fluorosilanes accelerates the drainage of liquid condensate on the inner wall of the smoke tube and the entrainment of solid particles such as soot or the like.
- the application of the hybrid polymers and fluorosilanes with different application methods can be carried out the treatment of the flue pipes in the Best diving process. This will make the exterior and Coated inside surfaces of the flue pipe. However, it can be considered to reduce material costs coating the smoke pipes on their inner surface restrict what is done with a spray process can be. Since it has been shown that the ceramic material at elevated temperature the hybrid polymers or the Liquid containing fluorosilane stronger and up to Saturation thus becomes useful in both cases the flue pipe to a temperature of, for example, 150 ° C heated up.
