Definitions

the invention relates to the operation of the protection of the pipeline of an H eizungssystems against destruction, by Züfugen of substances in the water supply system, whereby a protection is on the inside of the system.
the invention further relates to the production method of an aqueous mixture which is fed into the heating system with tap water.
the effect of the invention is achieved by feeding an aqueous mixture containing 50-90% by weight sodium silicate and several stabilizing substances.
a very thin protective layer is formed in the pipe system and in the heating elements and boiler, which reduces the frictional resistance in the system and prevents dirt and limescale deposits.
An additional advantage of this new agent is that small cracks and leak damage in the system are sealed by a thin, but very protective coating, which is mainly formed by the added sodium silicate.
PH-increasing substances are added to the mixture.
phosfaat such as Na 3 Po 4 12H 2 0.
the mixture according to the invention and the effect achieved thereby - is further expanded by adding ethylene glycol in an amount of 5-20 percent by weight, which reduces the freezing of the system.
the mixture of the invention is made from 50-90% Na 2 OSiO 2 , 5-30% Na 3 Po 4 12H 2 O in 10-45% H 2 O.
the soda water glass used is 27.5% Si0 2 and 30% dry matter.
the product is commercially available in the form of an aqueous solution.
the trisodium phosphate used contains 42.5% Na 3 PO 4 and about 50% H 2 0 .
the mixture is further diluted with a maximum of 250 liters of water.
This solution is filled into a heating system as a heat transfer medium.
a thin protective film forms on the walls of the duct systems, H eizungs instituten and boiler.
This protective layer effectively prevents the build-up of dirt on the walls of the system and thus an almost ideal heat transfer takes place.
