Embodiment Construction

[0038] The present invention is further described below in conjunction with the examples, and the specific experimental scheme is shown in Table 2. 1. Add 2 grams of dried stalks to 1 mm length into 100 grams of water, start stirring, and after the temperature rises to 40° C., add 1 gram of starch After the temperature rises to 80°C, add 0.4 gram of lime and 0.1 gram of NaCl, stir for 20 minutes, and cool naturally to obtain the desired product, and its pH value is measured to be 8.5.

[0039] 2. Add 2 grams of dried and chopped 1mm straw to 100 grams of water and start stirring. After the temperature rises to 30°C, add 1 gram of starch. After the temperature rises to 70°C, add 0.1 grams of lime and 0.3 grams of NaCl, stirred for 40 minutes, and cooled naturally to obtain the desired product, whose pH value was measured to be 8.3.

[0040] 3. Add 5 grams of dried and chopped 2mm straw to 100 grams of water and start stirring. After the temperature rises to 30°C, add 0.5 grams ...

Abstract

The present invention relates to an EEJL-1 green environment-protecting raise dust covering agent and its preparation method. Said covering agent is formed from water, straw, starch, lime powder and additive, their ratio is 100:2-10:0.5-8:0.1-0.6:0.1:-0.6 (weight ratio). Its preparation method includes the following steps: adding 2-10 portions of straw into 100 portions of water, stirring and heating to 30-50 deg.c, under the condition of continuously stirring adding 0.5-8 portions of starch, heating to 60-100 deg.C and adding 0.1-0.6 portion of lime powder and 0.1-0.6 portion of additive, then stirring for 20-40 min. and natural cooling so as to obtain the invented raise dust covering agent which has no pollution, is good in dust-suppressing effect and low in cost.

Description

technical field [0001] A green and environment-friendly flying dust covering agent and a preparation method thereof belong to the field of dust suppression materials. Background technique [0002] With the development of society and the improvement of people's living standards, environmental protection and effective use of resources have become the focus of common attention of all countries in the world. Due to the environmental pollution caused by flying dust and the waste of resources caused by traditional dust control technology, as well as the secondary pollution caused by it, people from all walks of life have attracted more and more attention from all walks of life. Our country is in a period of rapid economic development, with many construction projects. The dust pollution caused by various municipal construction sites, material storage yards, demolition sites and other open dusty sites such as bare ground has greatly endangered people's normal life and health. , des...
