Description

The invention relates to methods for producing disinfectant-detergents for special products from black fabrics.

Known methods for producing disinfectant-detergents are aimed at obtaining compositions having these properties due to the presence of ingredient (s) in the disinfectant-detergents having the properties of strong oxidizing agents, which adversely affects products from black fabrics, since the fabric acquires " whitish "shade.

A known method for producing a disinfectant-detergent for colored fabrics by mixing ingredients of the following composition: soap powder, sodium soap based on higher fatty acids, sodium alkylbenzenesulfonate (sulfonol), syntanol, sodium tripolyphosphate, citric acid sodium, soluble sodium silicate, carboxymethyl cellulose (K ), sodium chloride, polyvinylpyrrolidone, optical brightener, antifoam, perfume, enzyme preparation (enzymes), sodium sulfate and water (RU 2167193 C1, 05.20.2001).

However, a disadvantage of the known method is that the product obtained by this method has an undesirable effect of active oxygen on products made of black fabric, since this reduces the brightness of the fabric, a white coating appears, the fabric acquires a matte shade, in addition, the product loses its active properties during storage .

The objective of the invention is to eliminate the undesirable properties of a disinfectant-detergent, increasing the shelf life of the product without losing its activity.

The technical result of this invention is obtained by obtaining a disinfectant-detergent in the form of granules at a certain sequence of stages of the production method, introducing components in a certain sequence and, in addition, introducing dyes into the composition to ensure their integrity, preservation of their activity and security during storage.

In the apparatus of the vibro-boiling layer (VKS), the liquid raw materials atomized by the nozzle and the dry components are in contact. During spraying, solid particles are introduced into droplets of liquid, part of the water evaporates, and the rest of its mass binds to solid components. Anionic surfactants of 10 wt.%, An aqueous solution of sodium silicate of 2-3 wt.%, Nonionic surfactants of 4 wt.% Are used as liquid components, an antifoam of 0.4-0.5 wt.% Is added. Solid components are sodium tripolyphosphate 20-23 wt.%, Sodium sulfate up to 100 wt.%. Add fragrance 0.02 wt.%. Bulk raw materials from consumable bins with the help of weighing batchers are continuously fed via a screw conveyor to the section of the apparatus on the grid of the first zone, where the temperature is set at 60 ° C, then liquefied, after which the process of spraying liquid components occurs. To obtain the most durable granules, it is necessary to spray nonionic surfactants first, for example, such as neonol or syntanol 4 wt.%.
