Description

The invention relates to household chemicals, in particular, compositions intended for washing all types of dishes.

The aim of the invention is to increase the flowability and reduction of the formation, increase the degreasing ability while reducing the consumption of the composition during its use. Example. Preparation of the composition. The components are mixed at the temperature of the production room and at atmospheric pressure in batch mixers. Soda ash, chloramine B, sodium tripolyphosphate is loaded into the mixer. Turn on the mixing device and mix for 5 minutes.

When the mixing device is running, the alkyl sulfonate - emulsifier (volgonate) is charged. After stirring for 3 minutes, sodium metasilicate is charged. The mixture is stirred for 5 minutes and transferred to a mixer, from where it is fed to the packing,

Formulations with other interchangeable chlorine-containing agents are prepared similarly.

. Sodium metasilicate is used as a crystalline hydrate with 9 molecules of water. Monochloramine HB is used as a chlorine-containing agent that provides disinfection, removal of pigment contaminants, and removal of unpleasant food odors.

or chloramine B, or sodium dichloroisocyanuric acid.

Chloramine B - crystalline, rat sodium benzenesulfamide. Monochl oramine HB - crystalline sodium salt of chloramide p-chlorobenzenesulfonic acid (10).

The main features that determine the performance of the filling equipment and the process line as a whole are flowability and dustiness.

To assess the flowability of powdered agents, various physicomechanical indicators are used: tensile strength (stickiness), compactibility, angle of collapse.

The tensile strength, as measured by the split cylinder method, directly reflects the strength of the bond between particles and, in addition to the flowability, characterizes the physical phenomenon of slip. Indirect indicators of flowability are compactibility and the angle of 25 of the collapse.

Compaction Y is determined by

formula

At (pH)

where-Oi is the density after the morning; jg p - density with free

filling in

The angle of collapse is determined by the method based on the collapse of the layer when opening a hole in the base of a rectangular container.

A technique based on the removal of dust from the fluidized bed is used to evaluate the dustiness. According to this technique, the dust ability corresponds to the amount of dust removed from the bed at an upward air velocity of 0.093 m / s. In order to ensure the satisfactory performance of filling equipment, non-abrasive dishwashing agents must not exceed the following physical and mechanical properties: tensile strength (stickiness) 150 608220

200 Pa, compactibility 24%, angle of collapse 75 degrees, dustiness

2%.

The formulations and properties of the proposed composition in comparison with the known are given in the table.

A decrease in the numerical value of the physicomechanical indicators indicates an improvement in the technological properties of the powdery means, i.e. To increase the flowability and reduce the formation of pitch, one should strive to reduce the numerical values of tensile strength, compactibility, angle of caving, and dustiness. As follows from the table, the proposed composition exceeds the known in all respects m.
