Problems solved by technology

The most widely used inorganic deicing agents in the world are mainly chlorine salt deicing agents, and the most commonly used substances are sodium chloride (NaCl), calcium chloride (CaCl 2 ) and magnesium chloride (MgCl 2 ), wherein NaCl accounts for 98% of all usage; although organic deicing agents based on calcium magnesium acetate (CMA) have the characteristics of no pollution and environmental protection, due to expensive raw materials, their ability to melt snow is not as good as that of sodium chloride. The limit temperature of the product is -12°C, and it has disadvantages such as dust and pungent sour taste when spreading, and is not widely used.
[0003] At present, there are still the following problems in the preparation and application of road deicing agents: (1) when chlorine salt deicing agents provide a convenient way for people to deal with ice and snow, they are also eroding the surrounding soil environment and water bodies. Nega

Embodiment 1

[0079] This example provides a method of using straw powder to prepare the stock solution of ice-melting agent and an environmentally friendly ice-melting agent. The method specifically includes the following steps:

[0080] Step 1, the first potato enzymatic fermentation:

[0081] 1.1 Weigh the potatoes, wash them, grind them into mince with a grinder, and add water for 30 minutes at 60°C;

[0082] 1.2 Weigh the high-temperature-resistant amylase and put it into the potatoes obtained in step 1.1, raise the temperature in a water bath to 90°C for liquefaction for 60 minutes, then cool down to 60°C, add glucoamylase for 60 minutes, and then cool down to 30-40°C; among them, the high-temperature-resistant amylase and The amount of glucoamylase is 1% to 3% of the mass of potatoes;

[0083] 1.3 Mix yeast and acetic acid bacteria into the product obtained in step 1.2, then mix in rice bran and bran, adjust the humidity of the material to 80%, then pour it into the fermentation tank ...

Embodiment 2

[0102] This example provides a method of using straw powder to prepare the stock solution of ice-melting agent and an environmentally friendly ice-melting agent. The difference between this example and Example 1 is that in this example, the amount of solubilizer and stabilizer 20% of the quality of environmentally friendly ice melting agent.

Abstract

The invention discloses ice melting agent raw liquor, a method for preparing the ice melting agent raw liquor through straw powder and an application of the ice melting agent raw liquor. The method comprises the following steps of performing potato-straw fermentation circulation for many times, collecting potato fermentation filtrate obtained through the potato-straw fermentation circulation each time for mixing to obtain filtrate a, collecting straw fermentation first filtrate obtained through the potato-straw fermentation circulation each time for mixing to obtain filtrate A, mixing the filtrate a with the filtrate A in the equal volume, and adjusting pH to neutral so as to obtain the ice melting agent raw liquor; and adding a solubilizer and a stabilizing agent to the ice melting agent raw liquor to obtain an environmental-friendly type ice melting agent. According to the ice melting agent raw liquor and the method for preparing the ice melting agent raw liquor disclosed by the invention, the potato-straw fermentation circulation is performed for many times, two stages of potato enzymolysis fermentation and straw enzymolysis fermentation are integrated, the freezing point and the ice melting rate of obtained products are both close to those of a sodium chloride solution having the same concentration, no production of waste water and waste materials in the production procedure is realized, trash is utilized, the raw material cost of new products is greatly reduced, influence to environment is small, and the application range is wide.

Description

technical field [0001] The invention belongs to the field of environmental technology, and in particular relates to an ice-melting agent stock solution, a method for preparing the ice-melting agent stock solution by using straw powder, and an application thereof. Background technique [0002] The ice-melting agent is mainly used in winter airports, highways, squares, parking lots, railways, urban streets and other areas covered by ice and snow. After use, it can melt ice and snow and prevent freezing. At present, there are many kinds of deicing agents, which are mainly divided into inorganic salts and organic deicing agents. The most widely used inorganic deicing agents in the world are mainly chlorine salt deicing agents, and the most commonly used substances are sodium chloride (NaCl), calcium chloride (CaCl 2 ) and magnesium chloride (MgCl 2 ), wherein NaCl accounts for 98% of all usage; although organic deicing agents based on calcium magnesium acetate (CMA) have the c...
