Definitions
- the present invention concers a method for coa- ting of surfaces with a porous, sorbating material/com ⁇ pound, called "porous material” below, prefarably a ther- mically insulating and condensation-preventing coating and a material for this coating.
- porous material BACKGROUND TECHNICS It is among others by the Swedish patent published publication published by a Swedish patent published by a binder including different substances. In the finished product it is only the porous material which gives the compound its condensation-preventing characteristics. The binder only has the object to keep the porous material on the surface which is to be prevented from condensation.
- the porous material can vary between 5 and 20 % in the wet compound of materials.
- amounts of porous material of 15 % and more will make the compound of materials so dry that it can not be applied in a normal way, e.g. sprayed on a surface.
- the amount of porous material in itself can be increased provided that it is stirred and disintegrated during the mixing in of the same, but this will give a coating which is considerably less porous and which by that will become deteriorated characteristics.
- the technics described in Se-C-387 681 only are valid for amounts of porous material up to 15 %.
- the characteristics of the product itself are deteriorated at the present manufacturing method.
- the only function of the binder is to bind the porous gra ⁇ nules to each other into a porous lattice and to bind this lattice to the surface which is to be condendation- protected.
- a big part of the binder is soaked into the porous material where it has no function.
- the finished compound must con ⁇ tain more binder but wat is demanded to give the conden ⁇ sation-protecting coating a good adherence to the treated surface.
- the sorbation-capability of the porous material will be reduced as the pores partly are filled with binder and eventually other additives.
- the purpose whith the present invention is to bring about a method for coating of surfaces with a po- rous material, preferably a thermically insulating and condensation-preventing coating, and a material for this coating to be used at practising of the method.
- the me ⁇ thod according to the invention is characterised in that the porous material is sprayed in the shape of granules or powder on said surface and mixed with a binder during the spraying.
- the compound of materials which is sprayed and which is constituting the coating in question compri ⁇ ses a porous material with a bulk density of highest 150 kg/m 3 and a binder which can be a powder or which can be dispersed or dissolved in a liquid.
- the material compound according to the invention is characterised in that the porous material constitutes more than 15 % (percentage of weight) of the material compound at application on the surface which is to be coated. More details and characteristics concering the method respectively the material compound according to the invention will be clear from the description below and from the claims.
- porous material can be forced out from the nozzle in a helical movement in the air in front of each nozzle by means of a sprayer and the very pressure which is demanded for the fluidizing/transport and/or by means of more air.
- nozzles are mentioned “powder nozzles” below and are mainly centrally located in the nozzle device.
- each powder nozzle one or more outer liquid nozzles are arranged, from which binder is sprayed by means of air or high pressure.
- These outer nozzles are placed in that way that they mainly surround the powder nozzles and showing a tangential spraying direction rela ⁇ tive to the main spraying direction of the device, which causes that the binder, atomized by the pressure, will surround the porous material in a helical movement making the porous material and the binder to mix effectively in the air before reaching the surface which shall be coa ⁇ ted.
- a control of the light porous mate ⁇ rial is achieved contributing to a completely even coa- ting on the surface.
- the proportions between the porous material and the binder can be variably varied. It has surprisingly been prooved that the mixing proportion between the porous material and the binder can vary between 1,5:1 and 9:1 giving sufficient properties regarding condensation protection and durability.
- the mixing proportion 1,5:1 gives a higher durability but lower condensation preventing proporties, whilst the mix ⁇ ing proportion 9:1 gives very good condensation preven ⁇ ting proporties but a lower durability.
- an advantage with the method according to the invention is its flexibility. It is e.g. simple to vary the binder in that way that it fits for the base surface which is to be coated. By not mixing the porous material whith the binder until after the spray nozzles or in any of those one will be independent of the choice of binder. By e.g. using more transport hoses for the binder it is possible to use binders which are constitu ⁇ ted by two or more components in order to thereby lower the hardening time for the coating. The production method gives the same flexibility regaring the choice of harde- ning method. Each user therefore can choice if he likes to have physical or a chemical hardening, convection oven, IR-oven, frequency oven, microwave oven etc.
- porous, sorbating material By adding different additives as well as by mixing different porous material a product will be achieved which also is fire-protecting, mould-retarding, bacteria-retarding and smell-removing and which also by means of a suitable pig ⁇ ment can be given a desired colour.
- the porous, sorbating material also can be pre-treated with a wetting agent, which increases the sorbating capability of the finished coating.
