Embodiment 1

[0031] A degradable dust-proof film shell agent, comprising the following components in parts by weight: 28 kilograms of carboxymethyl cellulose, 15 kilograms of dextran, 15 kilograms of maltodextrin, 15 kilograms of pregelatinized starch, and 10 kilograms of polyvinyl alcohol kg, 10 kg of sodium nitrate, 10 kg of sodium hexametaphosphate, and 10 kg of talcum powder.

Embodiment 2

[0033] A degradable dust-proof coating agent, comprising the following components in parts by weight: 40 kilograms of ethyl cellulose, 25 kilograms of curdled polysaccharide, 25 kilograms of hydroxyethyl starch, 25 kilograms of pregelatinized starch, and 20 kilograms of sodium polyphosphate kg, 20 kg of sodium sulfate, 20 kg of polyvinyl alcohol, and 20 kg of talcum powder.

Embodiment 3

[0035] A degradable dust-proof film shell agent, comprising the following components in parts by weight: 30 kilograms of hydroxypropyl methylcellulose, 20 kilograms of xanthan gum, 20 kilograms of carboxymethyl starch, 20 kilograms of pregelatinized starch, coke Sodium phosphate 15 kg, sodium silicate 15 kg, sodium hexametaphosphate 15 kg, dextrin 15 kg.

[0036] How to use and precautions:

[0037] The dust-proof film and shell agent can be sprayed by mechanical and manual spraying or professional spraying stations (equipment, vehicles) and laying fixed pipelines. It can be evenly sprayed on the surface of the material to achieve the purpose of dust reduction and dust prevention. The specific dosage can be adjusted according to the site conditions.

[0038] (1) Manual spraying is suitable for sites with an area of ​​less than 1,000 square meters. Use manual pressure spraying devices and push-pull sprinklers to spray the material area evenly. The push-pull sprinkler can be p...

Abstract

The invention discloses a degradable dustproof film shell agent. The degradable dustproof film shell agent comprises the following components in parts by weight: 28-40 parts of a cellulose derivative,15-25 parts of microbial polysaccharide gum, 15-25 parts of modified starch, 15-25 parts of a film aid, 10-20 parts of a toughening agent, 10-20 parts of a humectant, 10-20 parts of a reticular accelerator and 10-20 parts of a flow dispersing agent. The dustproof film shell agent is prepared by refining and compounding a plurality of pure natural vegetable gums, and problems in dispersibility, permeability and dry strength in the prior art are solved by combining an instant dissolving technology in a use method; and since the film shell agent has good film-forming property, evaporation of moisture in dust can be prevented, and the film shell agent has good evaporation resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a degradable dust-proof membrane shell agent. Background technique [0002] With the advancement of science and technology and the continuous improvement of people's living standards, human beings have higher and higher requirements for the quality of living environment. Among the many public hazards in the world, dust has become the largest source of pollution, with complex components and a wide range of sources. Among them, PM2.5 is an important part of smog and the main direction of air pollution control. There are many sources of dust pollution. In recent years, urban infrastructure construction, especially open-air construction, mining, sandstone coal transportation, urban bare ground, and piles of garbage and waste will all form dust pollution, which will cause dust pollution. Pollution has become increasingly serious, seriously affecting the environment ...
