Definitions
- the present invention relates to a granular detergent builder in the form of a cogranulate from a mixture of sodium hydrogen carbonate and crystalline phyllosilicates of the general formula NaMSi x O 2x + 1 * yH 2 O, where M is sodium or hydrogen, x is a number from 1.9 to 4 and y is a number from 0 to 20 and its use.
- alkali tripolyphosphates such as sodium tripolyphosphate displaced new builder systems, which usually consist of a synthetic, crystalline aluminosilicate (e.g. zeolite A), an alkali source (e.g. soda) and at least a cobuilder.
- alkali tripolyphosphates such as sodium tripolyphosphate displaced new builder systems, which usually consist of a synthetic, crystalline aluminosilicate (e.g. zeolite A), an alkali source (e.g. soda) and at least a cobuilder.
- cobuilders individually or in combination with each other - or in combination with other substances usually nitrilotriacetic acid or its Salts, phosphonates and also polycarboxylates, especially those based on acrylic and / or Maleic acid used.
- EP-0 425 428 B1 describes a process for the production of crystalline sodium silicates known with a layer structure, in which amorphous sodium silicate with a water content from 15 to 23% by weight in a rotary kiln at temperatures from 500 to 850 ° C is calcined, the calcine is fed to a roller compactor after breaking and grinding and then, after shredding and sieving, the school pens obtained to a granulate a bulk density of 700 to 1000 g / l can be processed.
- DE-A-43 30 868 describes a process for the production of compacted, granular Sodium silicates, in which the sodium silicate with an average grain diameter of ⁇ 500 ⁇ m first mixed with a material that increases its hardness before you use it by compacting, crushing and sieving into a press granulate with grain sizes of 0.1 transferred to 5 mm.
- EP-A-0 164 514 describes the use of crystalline sodium silicates for softening of water containing calcium and / or magnesium ions.
- EP-A-0 563 631 discloses cogranulates with high bulk density that easily disintegrate in water from alumosilicates and crystalline sodium silicates with a layer structure, a process for their manufacture and use known.
- a disadvantage of all detergent formulations containing alumosilicate is the water-insolubility the aluminosilicates, which among other things causes an increased sewage sludge load. It is also disadvantageous that during the processing of aluminosilicates or in Can form larger agglomerates in the course of their use, so that the use of cobuilders is necessary to break up the aluminosilicates into a suspension of fine primary particles, since Agglomerates of aluminosilicates - especially zeolite A - do not tend to disintegrate have in the primary particles.
- the granules described in the aforementioned prior art are generally satisfactory Softening of water, whereby it would be beneficial to increase it further To be able to realize water-softening effect so that anionic surfactants are effective can develop more.
- Detergent formulations such as those described in PCT / WO 92/18594, have in 1% solution in distilled water at 20 ° C a pH of 10 to 11.
- Detergent builder formulations that include as alkali source sodium carbonate (soda) contain, have an inherent pH of> 10 on alkali-reduced detergents on the other hand need other builders or builder combinations in which it is desirable would be if the builder formulations have an intrinsic pH in the range of ⁇ 10.
- a low pH value contributes significantly to the protection of sensitive tissues during the washing process.
- Intrinsic pH is in the range ⁇ 10, which have an increased water softening effect, and which reduce the sewage sludge pollution due to their water solubility.
- the granular detergent builder preferably has a bulk density of 900 900 g / l.
- the degree of reaction between crystalline layered silicate and sodium hydrogen carbonate is preferably between 5 and 60%.
- the sodium silicates in the granular detergent builder according to the invention preferably have an SiO 2 / Na 2 O ratio of (1.9 to 2.1): 1.
- the granules according to the application can be produced through a process which is characterized in that sodium bicarbonate and Sodium silicate mixed in powder form; that the mixture is fed into a zone, in which it rotates in the opposite sense between two Rolling under pressure is compacted into a solid (Schulpen); that one is the solid crushed; and that one finally the desired grain sizes from the oversize and Separates undersize.
- the pressure of the rollers preferably corresponds to a line pressing force > 20 kN / cm with 200 mm roller diameter.
- the Schulpen preferably have a temperature of ⁇ 70 ° C.
- the crystalline sodium disilicate contained in the cogranules according to the invention with Layer structure are slowly water-soluble, whereby a sludge relief of the sewage treatment plants is achieved.
- Sodium silicate can be used as a component in the detergent or cleaning agent formulation Soda may be omitted entirely, since the crystalline sodium disilicate supplies an alkali are.
- the invention also relates to the use of the granular detergent builder according to the invention in detergents and cleaning agents.
- the abovementioned washing and cleaning agents preferably contain 3 to 60% by weight of the granular detergent builder.
- the detergents and cleaning agents can additionally other detergent builders and others Detergent additives included.
- the other detergent builders are preferably sodium tripolyphosphate, Zeolite A, Zeolite P, amorphous silicates, water glass and / or alkali metal carbonates.
- the other detergent ingredients are preferably surfactants, bleaches, Bleach activators, bleach stabilizers, enzymes, polycarboxylates and / or carboxyl-containing Co-builders.
- the particle size distribution is determined using a 50 gram sample by sieve analysis (used Apparatus: RETSCH VIBRATONIC) determined and from this the average particle diameter determined via a graphical evaluation.
- the granules to be examined are passed through a sieve (710 ⁇ m) in the sample preparation sieved. With the undersize, the rate of decay in water (18 ° dH) becomes dependent on the time a MICROTRAC Series 9200 (from Leeds & Nothrup GmbH).
- the pH is measured in a 1% solution in distilled water at 20 ° C a digital pH meter CG 840 from SCHOTT.
- the degree of preservation provides information about what percentage of the starting components are present side by side in an unreacted form.
- the temperature increase is determined which is achieved through the neutralization of the heat released and the corresponding heat of solution when 25 grams of the cogranulate sample to be measured are added to 100 grams of distilled water.
- the degree of maintenance is related to the temperature increase of the zero value, which is achieved if instead of the cogranulate, only a corresponding physical mixture of the starting components is used in the determination.
- the filtrate must be made strongly acidic (pH ⁇ 2.5) due to possible reprecipitation with HCl, so that the excess carbonate in the form of CO 2 can be removed from the filtrate by stirring.
- the calcium remaining in the filtrate is then determined complexometrically.
- the calcium binding capacity generally referred to as the KBV value, was calculated by forming the difference with the original calcium content.
- the result is a solution with 3 ° dH.
- the solution is kept in a water bath thermostat (ERWEKA) with stirring at 20 ° C. and 1 gram of the cogranulate sample to be measured is added.
- ERWEKA water bath thermostat
- the sample is then filtered through a folded filter (Ederol 12). If the sample to be examined contains carbonate, the filtrate must be made strongly acidic (pH ⁇ 2.5) due to possible reprecipitation with HCl, so that the excess carbonate in the form of CO 2 can be removed from the filtrate by stirring.
- the magnesium remaining in the filtrate is then determined complexometrically.
- the magnesium binding capacity was calculated by forming the difference with the original magnesium content.
- SKS-6® sodium disilicate
