example 1

[0018] First, take 300g of coconut meat, mix it with 200mL of water, put it in a juicer to squeeze the juice, collect the juice, and put it in a fermenter for 4 days at 30°C. After the fermentation is over, collect the juice in the fermenter. Put the materials in a sterilization tank, sterilize at 100°C for 15 minutes, let the sterilized materials stand for 9 hours, absorb the upper layer of oil with a straw and place them in a flask; put the above flask in a water bath , heat up to 80°C, keep warm for 20min, remove the moisture in the material, then add 20g of glucose and 0.5g of oxalic acid into the flask, raise the temperature to 95°C, and react with magnetic stirring for 3h. After the reaction is completed, filter the reaction solution and collect Filtrate to obtain coco-glucoside, set aside; take 200g of broken steps fruit, wash 3 times with water, put the washed fruit in a beaker filled with 4L water, and heat it to boiling, keep it warm and boil for 2 hours , filter, co...

[0024]First, take 250g of coconut meat, mix it with 150mL of water, put it in a juicer to squeeze the juice, collect the juice, and put it in a fermenter for 3 days at 27°C. After the fermentation is over, collect the juice in the fermenter. Put the materials in a sterilizing tank, sterilize at 95°C for 12 minutes, let the sterilized materials stand for 8 hours, absorb the upper layer of oil with a straw and place them in a flask; put the above flask in a water bath , heat up to 75°C, keep warm for 17min, remove the moisture in the material, then add 17g of glucose and 0.4g of oxalic acid into the flask, raise the temperature to 90°C, and react with magnetic stirring for 2h. After the reaction is completed, filter the reaction solution and collect The filtrate was used to obtain coco-glucoside, which was set aside; take 150g of the broken step fruit, wash it twice with water, place the washed fruit in a beaker filled with 3L of water, and heat it to boiling, keep it warm and bo...

Abstract

The invention relates to a preparation method of a mine composite foam dedusting agent, and belongs to the technical field of preparation of dedusting agents. The method comprises the following steps of firstly squeezing copra and then fermenting to obtain coconut oil; reacting the coconut oil with glucose and oxalic acid to obtain coco-glucoside; boiling cordia dichotoma fruits and carrying out mixed fermentation with soybean protein and papain, and collecting a concentrated solution; and finally stirring and mixing the concentrated solution with the prepared coco-glucoside and carboxymethyl cellulose to obtain the mine composite foam dedusting agent. According to the prepared mine composite foam dedusting agent, the expansion rate reaches 150-200 times, the mine composite foam dedusting agent has good wettability and relatively high dust removal property, the removal rate on whole dust reaches over 96%, and the removal rate on respirable dust reaches over 87%; and the mine composite foam dedusting agent does not contain any corrosive substance so as to not corrode dedusting equipment.

Description

technical field [0001] The invention relates to a method for preparing a composite foam dedusting agent for mines, and belongs to the technical field of dedusting agent preparation. Background technique [0002] Coal mine production is a key industry of productive dust hazards. At present, my country's coal mining is dominated by underground mining. Due to the narrow space for underground coal mining, variable working locations, and poor ventilation, a large amount of dust is generated during underground coal mining, excavation, reloading, and transportation. Without dust prevention measures, the dust concentration in the fully mechanized mining face can be high. Up to 2500~3000mg / m 3 , some coal mines are even as high as 8000-10000mg / m 3 above. Excessive concentration of underground dust can cause pneumoconiosis, which seriously threatens the personal safety and health of miners and affects the working environment at the same time. [0003] At present, in order to impr...
