Long-acting water-coal-slurry stabilizer

Abstract

A long-acting water-coal-slurry stabilizer is prepared from the following raw materials in parts by weight: 16-32 parts of modified attapulgite, 2-4 parts of galacturonic acid, 3-5 parts of 1,2-benzisothiazolin-3-one, 8-12 parts of sodium lignin sulfonate, 2.5-3 parts of water-soluble polysaccharide, 20-30 parts of water, 12-16 parts of mercaptoacetic acid 2-ethylhexyl acrylate, 3-6 parts of diallydimethylammonium chloride-acrylamide polymer, 6-9 parts of xanthan gum, 4-8 parts of sodium polyacrylate, 4-6 parts of modified cellulose, 3-7 parts of carboxyethyl cellulose, and 3-6 parts of polyethyleneglycol. The long-acting water-coal-slurry stabilizer has the beneficial effects that the long-acting water-coal-slurry stabilizer cannot produce sand sedimentation and has excellent dispersing effect, water-coal-slurry can be wetted fully, viscosity is reduced effectively, thermal stability is good, the stabilizer is easy to store, and acting time is long.

Description

technical field [0001] The invention relates to a long-acting coal water slurry stabilizer. Background technique [0002] Coal-water slurry is a low-pollution, high-efficiency, pipeline-transportable oil-substituting coal-based fluid fuel that is obtained through physical processing of about 65% coal, 34% water and 1% additive. It has changed the traditional way of burning coal, showing great advantages in environmental protection and energy saving. Especially in recent years, after adopting the technical route of recycling waste, the environmentally friendly coal-water slurry has been successfully developed, which can greatly improve the environmental protection benefits of coal-water slurry without increasing costs. Under the protection of my country's rich coal resources, coal water slurry has also become the most basic and economical clean energy to replace oil, gas and other energy sources. However, since coal-water slurry is a coarse-grained suspension, it is a dynam...
