Übersetzung für "Mechanical agitation" in Deutsch

The dilutant is added to the dissolved resist gradually by mechanical stirring or agitation.

This is added to the dissolved resist gradually by mechanical stirring or agitation.

There is no mechanical agitation of the material.

Cubic surfactant gels react highly elastic upon mechanical agitation.

In this known device, no means are provided for additional mechanical agitation of the mash.

The dynamic viscosity increases with increasing shear stress, i.e. with increasing mechanical agitation.

The surface roughness is achieved without the dust generation otherwise typical of crystallization processes applying mechanical agitation.

This process can be carried out with the aid of a stator-rotor process, or of an oscillating process or by means of mechanical agitation.

Storage time may be further reduced when stirring the dispersion at 65° C. in a closed vessel, presumably because alterations the speed of which is controlled by diffusion processes on simple storage of the dispersion are accelerated by mechanical agitation.

Its addition ensures that virtually no foam formation takes place even with extremely great mechanical agitation of the liquor, such as takes place, for example, in the bottle cleaning plants of breweries.

These compositions are particularly suitable for industrial crockery-cleaning and bottle-cleaning plants which are operated with considerable mechanical agitation of the liquor within a highly alkaline pH range.

These compositions are particularly suitable for industrial crockery and bottle washing plants which are operated within the highly alkaline pH range and with vigorous mechanical agitation of the liquor.

In producing polyvinyl chloride by the suspension polymerization method, the monomer or monomer mixture is finely distributed in the aqueous phase by mechanical agitation, stabilized with the aid of protective colloids, and polymerized in the presence of free radical initiators.

Although, in the case of mechanized cleaning processes for bottles, crockery and the like in the industrial sector, which are carried out with considerable mechanical agitation, the low foam content of the surfactant systems mentioned is very desirable, the removal of soil in the short time of throughput available for the material to be cleaned, and also the soil uptake capacity, are frequently not adequate and are in need of improvement.

Owing to the considerable mechanical agitation of the liquor, the system must also have as low a foam content as possible, or be free from foam, since excessive foam formation can lead to interruptions in the performance of the plant, for example if the soil accumulating in the layer of foam cannot be discharged to an adequate extent.

Immediately after acylation has been completed, the aqueous alkali metal hydroxide solution for the second process step is introduced, without cooling and with vigorous mechanical agitation, into the resulting reaction mixture, which is already at reaction temperature, the isobutyric acid present being neutralized and cyclization to form the hydroxypyrimidine derivative being achieved.

It is seen from Table 1 above that the vinyl polyether alcohols and polyether sulfonates show an advantageous reduction of surface tension and a marked drop in foaming propensity, which is an advantage in all industrial cleaning processes involving high mechanical agitation.

In the two-component process (see, for example, U.S. Pat. No. 2,874,063), toner particles having a particle size of, for example, 5 to 30 ?m and comprising a base polymer (for example 70 to 95% by weight), one or more pigments (for example 3 to 20% by weight) and if appropriate other additives, are charged triboelectrically by mechanical agitation with magnetic carrier particles of a particle size of, for example, 30 to 200 ?m (for example iron, coated iron or ferrites) and in this way form a layer on the surface of the oppositely charged carrier particles.

Initiator and catalyst are advantageously initially introduced and the monomers are metered in with or without solvents with mechanical agitation to provide good distribution of the monomers and with cooling in order to maintain the intended temperature of the exothermic reaction.

According to the invention, the radiologically amorphous water-glass is converted quantitatively into crystalline sodium silicate by being heat-treated in the finely ground state under mechanical agitation, the outer, already crystallized shell of each grain, being knocked off so that the required heat can penetrate into each grain at a sufficient speed while the crystallization continues.

The principal constituents in detergent and cleaning agent formulations for cleaning processes entailing intense mechanical agitation, for example for bottlewashing or for use in domestic dishwashers, are alkaline builders, such as phosphates, silicates, carbonates and even caustic alkalis.

In the production of polyvinyl chloride resins by suspension polymerization, the monomer or monomer mixture is finely distributed in the aqueous phase by mechanical agitation, stabilized by addition of protective colloids or suspension stabilizers, and polymerized in the presence of free radical catalysts.

The mixing of the two liquid mixtures can be conducted by any method which achieves vigorous mingling of the liquid with the physiologically acceptable gas with turbulence, for example by mechanical agitation or by ultrasound or by withdrawing one solution into a hypodermic syringe, preferably the tenside-containing solution, and emptying the syringe into the second mixture with the use of maximum pressure and high efflux velocity and preferably also by subsequent vigorous shaking, under conditions whereby during all mixing steps sterile conditions are ensured.

The ground material is preferably contacted with a 5-50% by of an weight aqueous potassium hydroxide solution, at a temperature in the range of from room temperature to the boiling point of the mixture, during which thorough mixing of the reactant can be ensured by mechanical agitation.

The reaction mixture is preheated to the reaction temperature, it being possible to ensure good distribution of the reactants by mechanical agitation.

DE-OS 33 13 814 teaches a process for the hydrothermal production of clear potassium silicate solutions having a molar ratio of SiO2 to K2 O of 2.75:1 by digestion of crystalline silicon dioxide having an average grain size of from 0.1 to 2 millimeters ("mm"), characterized in that the aqueous potassium hydroxide solution is passed through a bed of silicon dioxide which is formed in a vertical tubular reactor with no mechanical agitation and which is fed downwards with silicon dioxide and a aqueous solution of potassium hydroxide.

In addition to the work of the cutting tools a slight mechanical agitation may be performed to assist the detachment from the foreign material on thecardboard, avoiding however that any disintegration of the cardboard itselftakes place in this method stage.

This is probably due to the fact that, in the course thereof, the mechanical agitation required for the agglomeration superimposes itself in an undesirable manner onto the flow motion of the powder suspended in the liquid medium as a continuum, as a result of which portions of product are discharged which have not yet passed through the agglomeration process to reach full "maturity" and therefore do not yet have the properties desired, which then impairs the pattern of properties of the entire product.
