Abstract

The invention relates to a special-purpose solid cleaning agent of a dish-washing machine and a preparation method thereof. The special-purpose solid cleaning agent consists of the following substances in percent by weight: 20%-50% of sodium hydroxide or / and potassium hydroxide, 15%-30% of sodium carbonate, 10%-20% of sodium metasilicate, 3%-6% of sodium dichloro isocyanurate or imidazolidinedione, 4%-8% of EDTA (Ethylene Diamine Tetraacetic Acid), 1%-5% of sodium citrate, 5%-10% of a dispersing agent PAA (Poly Acrylic Acid), 1%-5% of borax and the balance of water. The preparation method of the special-purpose solid cleaning agent comprises the following steps of preparing the solid substances according to a proportion of the formula; starting up a reaction kettle, and respectively adding the solid materials under stirring; adding water after all solid materials are added and uniformly stirred; starting to heat up inside the reaction kettle with the addition of water, so that the materials generate reaction; stirring reactants for cooling to 50 DEG C-60DEG C, and starting to discharge; metering and pouring moving materials to a product container when the moving materials are hot, cooling and forming to obtain a finished product. The preparation method disclosed by the invention is low in reaction temperature, good in reactant mobility, easy for finally forming, energy-saving, environment-friendly and high in efficiency.

Description

technical field [0001] The invention relates to a special solid cleaning agent for dishwashers and a preparation method thereof. Background technique [0002] The solid detergent used in dishwashers is currently widely used as solid powder both at home and abroad, but there is a problem that it is fed in batches and the frequency is frequent. Moreover, it is easy for solids to block the feeding port and the pipeline during use. There is a solid forming detergent developed at home and abroad, but its production process consumes high energy and has low efficacy. The process uses the reaction materials to be heated and melted. After mixing, the materials are cooled first, shaped, and then packaged. Since the forming agent is not easy to cool and solidify, it is time-consuming, labor-intensive, and energy wasted. Contents of the invention [0003] The purpose of the present invention is to provide a special solid cleaning agent for dishwashers and a preparation method thereo...
