Description

object The present application is a consumption indicator for mechanical Dishwashing liquid. In particular, the present application relates to consumer displays Cleaning or cleaning Cleaning aids in automatic dishwashing on Base.

At the automatic dishwashing In the household, cleaning agents are commonly used today in powder or Tablet form for a rinse placed in a metering chamber, i. for every new cleaning process must again Detergent be dosed. There are also cleaning and in particular cleaning aids which survive several rinses. For cleaning aids, which of the dishwasher dosed, exists in most commercial dishwashers a consumption indicator which signals to the consumer that corresponding Product refilled must become. In this way, for example, the consumption of rinse aid or Regenerating salt detected and the consumer a certain condition via acoustic or optical Indicators signaled.

For cleaning agents and the consumption of these detergents exist in the dishwashers however, no consumption indicators. Meanwhile exists beyond a variety of cleaning aids that are also not from The machine will be dosed, but spread over several rinses consume, for example, deodorants for the interior of the machine, Glass protection products or additional products for silver protection, increased cleaning performance etc..

Here the problem lies in the exhaustion of cleaning or cleaning Then indicate cleaning aids when the consumer enters buy the corresponding new product and place it in the dishwasher should.

to solution For example, the cleaning utensils will address this problem to be added to the appropriate dose-dispensable cleaning agents, see above that the Consumers buying a new pack of detergent get a new cleaning agent. This has the disadvantage that he to certain pack sizes for the detergent is bound; In addition, a separate sale of the cleaning aid not possible in this way.

task The present application therefore provided a consumption indicator, which the user of a cleaning or cleaning agent, which is introduced into the interior of a dishwasher and is consumed there only in the course of several cleaning operations, the exhaustion of the Indicates cleaning or cleaning agent. To meet him the requirements to adapt to the different cleaning or cleaning aids, should the consumption indicator in a simple manner preferably in of any size and shape be produced.

When polymeric carrier material for the cleaning boosters or additives are generally suitable all polymers or polymer mixtures. In the context of the present application preferred cleaning booster or Additives are characterized in that the polymeric carrier material at least one substance from the group comprising ethylene / vinyl acetate Copolymers, low or high density polyethylene (LDPE, HDPE) or mixtures thereof, polypropylene, polyethylene / polypropylene copolymers, Polyether / polyamide block copolymers, styrene / butadiene (block) copolymers, styrene / isoprene (block) copolymers, Styrene / ethylene / butylene copolymers, acrylonitrile / butadiene / styrene copolymers, acrylonitrile / butadiene copolymers, Polyether esters, polyisobutene, polyisoprene, ethylene / ethyl acrylate copolymers, Polyamides, polycarbonate, polyester, polyacrylonitrile, polymethylmethacrylate, Polyurethanes, polyvinyl alcohols contains.

Polyethylene (PE) is a collective name for polymers belonging to the polyolefins with groupings of the type CH ₂ -CH ₂ as a characteristic basic unit of the polymer chain. Polyethylenes are usually by polymerization of ethylene by two fundamentally different methods, the high-u. produced by the low pressure process. The resulting products are accordingly often referred to as high pressure polyethylenes and low pressure polyethylenes, respectively; they differ mainly in their degree of branching and, consequently, in their degree of crystallinity and their density. Both methods can be carried out as solution polymerization, emulsion polymerization or gas phase polymerization.

When high-pressure method branched low-density polyethylenes fall (about 0.915 to 0.935 g / cm ³⁾ and crystallinity of about 40-50%, which is as LDPE-type (low density polyethylene), respectively. Products with higher molecular weight u. consequent improved strength u. Stretchability bear the abbreviation HMW-LDPE (HMW = high molecular weight). By copolymerization of ethylene with longer-chain olefins, in particular with butene u. Octene, the pronounced degree of branching of the high-pressure process Herge polyethylene can be reduced; the copolymers have the abbreviation LLD-PE (linear low density polyethylene).

The macromolecules of the polyethylenes from low-pressure process are largely linear and unbranched. These polyethylenes, abbreviated to HDPE (from E high density polyethylene) have degrees of crystallinity of 60-80% u. a density of about 0.94-0.965 g / cm3. They are referred to as high or ultra high molecular weight products (about 200,000-5,000,000 g / mol or 3,000,000-6,000,000 g / mol) under the abbreviation HD-HMW-PE or UHMW-HD-PE are offered. Also, medium density (MDPE) products from blends of low and high density polyethylenes are commercially available. Linear P. with densities <0.918 g / cm3 (VLD-PE, from E very low density polyethylene) are only slowly gaining market significance.

polyethylenes have a very low water vapor permeability, the diffusion of Gases and flavorings u. ethereal substances by polyethylenes is relatively high. The mechanical properties are highly dependent on Molecular size and structure the polyethylene. Generally, degree of crystallinity increases. Density of polyethylenes with decreasing degree of branching and with shortening of the side chains. With the density increase shear modulus, hardness, yield strength u. Melting range; it decreases from shock resistance, transparency, swellability u. Solubility. With the same density, P.sup. Elongation, shock resistance, impact resistance u. Creep strength to. Depending on how you work in the polymerization you can products with paraffin wax-like Properties (MR around 2000) u. Highest toughness products (MR over 1 million) receive.

The Processing of polyethylene types can be done after all for thermoplastics Methods are done.

Polypropylene (PP) is the name for thermoplastic polymers of propylene with the general formula: - (CH ₂ -CH [CH 3]) _n -

Base for the Polypropylene manufacturing was the evolution of the process stereospecific polymerization of propylene in the gas phase or in suspension by Natta. This is done with Ziegler-Natta catalysts, increasingly but also initiated by metallocene catalysts and leads either to highly crystalline isotactic or less crystalline syndiotactic or to amorphous atactic polypropylenes

polypropylene characterized by high hardness, Resilience, Stiffness and heat resistance. Short-term heating of objects made of polypropylene is even possible up to 140 ° C. At temperatures below 0 ° C occurs a certain embrittlement the polypropylene, but by copolymerization of propylene with ethylene (EPM, EPDM) to much lower temperature ranges can be moved. Gen. let yourself the impact resistance of P. by modification with elastomers. The chemical resistance is good as with all polyolefins. An improvement of the mechanical Properties of P. can be achieved by strengthening with talc, chalk, wood flour od. Glass fibers. P. are in an even greater extent than PE oxidation u. sensitive to light, why the addition of stabilizers (antioxidants, light stabilizers, UV absorbers) is required.

polyether is one in the field of Macromolecular Chemistry Designation for Polymers whose organic repeating units are characterized by ether functionalities (C-O-C) held together. According to this definition belongs one Variety of structurally very different polymers to the polyethers, z. As the polyalkylene glycols (polyethylene glycols, polypropylene glycols u. Polyepichlorohydrins) as polymers of 1,2-epoxides, epoxy resins, Polytetrahydrofurans (polytetramethylene glycols), polyoxetanes, polyphenylene ethers (see polyaryl ether) or polyether ether ketones (see Polyetherketone). Not the polyethers are polymers with pendant ether groups calculated, as u. a. the cellulose ethers, starch ethers and. Vinyl ether polymers.

to Group of polyethers count furthermore also functionalized polyethers, d. H. Connections with a polyether scaffold, the laterally attached to their main chains still other functional Wear groups such. As carboxy, epoxy, allyl or amino groups etc. Versatile are block copolymers of polyethers and polyamides (so-called polyetheramides or polyether block amides, PEBA).

Polyamides (PA) are polymers whose basic building blocks are held together by amide bonds (-NH-CO-). Naturally occurring polyamides are peptides, polypeptides and the like. Proteins (Ex .: protein, wool, silk). The synthetic polyamides are, with a few exceptions thermoplastic, chain-shaped polymers, some of which have great technical importance as synthetic fibers u. Materials have been obtained. According to the chemical structure, the so-called homo-polyamides can be divided into two groups, the aminocarboxylic acid types (AS) and the diamine-dicarboxylic acid types (AA-SS, where A denotes amino groups and S denotes carboxy groups). The former are made of only a single monomer by z. B. polycondensation of a ω-aminocarboxylic acid 1 (polyamino acids) or by ring-opening poly cyclization of cyclic amides (lactams) 2.

Next The homopolyamides also some co-polyamides have gained importance. It is usual in these a qualitative u. quantitative indication of the composition z. Eg PA 66/6 (80:20) for from 1,6-hexanediamine, adipic acid u. e-caprolactam in the molar ratio 80:80:20 manufactured polyamides.

Because of their special properties P., which are exclusively aromat. Residues contain (eg those from ρ-phenylenediamine and terephthalic acid), under the Gattungsbez. Aramides or polyaramides summarized (Ex .: Nomex ^® ).

The most frequently used polyamide types (in particular PA 6 and PA 66) consist of unbranched chains with average molar masses of 15,000 to 50,000 g / mol. You are in solid state semi-crystalline and have degrees of crystallization of 30-60%. An exception are polyamides of building blocks with side chains or co-polyamides of very different components, which are largely are amorphous. Unlike the generally milky-opaque, semi-crystalline polyamides, these are almost crystal clear. The softening temperature the most common Homo-polyamides are between 200 and 260 ° C (PA 6: 215-220 ° C, PA 66: 255-260 ° C).

polyester is the collective name for Polymers whose basic building blocks are held together by ester bonds (-CO-O-) become. After their chemical structure, the so-called Homopolyesters can be divided into two groups, the hydroxycarboxylic acid types (AB polyester) u. the dihydroxy-dicarboxylic acid types (AA-BB polyester). The former are made of only a single monomer by z. B. polycondensation an ω-hydroxycarboxylic acid 1 or by ring-opening polymerization cyclic ester (lactone) 2 produced.

branched and crosslinked polyesters are used in the polycondensation of three or polyhydric alcohols with polyfunctional carboxylic acids. The polyesters are generally also the polycarbonates (polyester carbonic acid) expected.

AB-type P. (I) are u. a. polyglycolic acids, polylactic acids, polyhydroxybutyric [Poly (3-hydroxybutyric acid), Poly (e-caprolactone) s and polyhydroxybenzoic acids.

Purely Aliphatic AA-BB type polyesters (II) are aliphatic polycondensates Diols and dicarboxylic acids, the u. a. as products with terminal Hydroxy groups (as polydiols) for the preparation of polyester polyurethanes be used [z. B. polytetramethylene adipate. In terms of volume, the greatest technical significance have AA-BB type polyesters of aliphatic diols and aromatic dicarboxylic acids, in particular the polyalkylene terephthalates, with polyethylene terephthalate (PET), polybutylene terephthalate (PBT) and poly (1,4-cyclohexanedimethylene terephthalate) e (PCDT) as the main representative. These types of P. can by Co-use of other aromatic dicarboxylic acids (eg isophthalic acid) or by using diol mixtures in the polycondensation in their Properties widely varied and different application areas customized become.

Purely aromatic polyesters are the polyarylates to which u. a. which include poly (4-hydroxybenzoic acid). In addition to the previously mentioned saturated Polyesters can also be unsaturated polyesters from unsaturated dicarboxylic acids produced as polyester resins, especially as unsaturated polyester resins (UP resins), have achieved technical importance.

polyester are usually thermoplastics. Products based on aromatic Possess dicarboxylic acids pronounced material character. The purely aromatic polyarylates are characterized by high thermal stability.

When Polyurethanes (PUR) are polymers in whose macromolecules the Repeating units are linked by urethane groups -NH-CO-O-. Polyurethanes are generally prepared by polyaddition from or higher quality Alcohols and isocyanates obtained.

ever optional and stoichiometric relationship The starting materials are thus polyurethanes with very different mechanical properties as components of adhesives and paints (P. resins), as ionomers, as a thermoplastic material for bearing parts, Rolls, tires, rollers are used and as more or less hard elastomers in fiber form (elastofibres, short PUE for this Elastan od. Spandex fibers) od. As a polyether or polyester urethane rubber (EU or AU)

Polyurethane foams are produced in the polyaddition, when water u./od. Carboxylic acids are present, because these react with the isocyanates with elimination of uplifting and Foaming carbon dioxide. With polyalkylene glycol ethers as Diolen u. Water as a reaction component to get to flexible polyurethane foams, with Polyols and the like CFC propellant gases (especially R 11) are obtained polyurethane rigid foams and structural or integral foams. Additional auxiliaries needed are here z. As catalysts, emulsifiers, foam stabilizers (especially polysiloxane-polyether copolymers), Pigments, aging u. Flame retardants. To the manufacturer of also complicated shaped objects made of polyurethane foam in the 70s, the so-called RIM technology developed (reaction injection molding). The RIM Avail. based on rapid dosing u. Mixing the components, Injection of the reactive mixture into the mold u. fast curing; the Cycle time is just minutes. Using RIM technology u. a. Car body parts, Shoe soles, window profiles and television housing generated.
