Description
Technical field
The present invention relates to senior workplace ground technical field, particularly relate to a kind of Self-leveling abrasion-resistant ground and preparation method.
Background technology
Along with developing rapidly of fluohydric acid gas industry, produce waste residue anhydrous slufuric acid produced by fluohydric acid gas with sulfuric acid decomposition fluorite
The amount of calcium gets more and more.It is reported that often producing 10 tons of fluohydric acid gas will discharge 3.6 tons of industrial residue fluorgypsum, current domestic annual output
Output reaches more than 100 ten thousand tons, and relevant enterprise is had to take over bigger place for use and stacked, but the accumulation of fluorgypsum meeting serious environment pollution,
Actually the one of enterprise big millstone around one's neck, comprehensive control is turned waste into wealth the most in addition becomes the very important problem of enterprise.Additionally
Industrial residue exploitation new product is utilized to meet National Sustainable Development Strategies requirement.
Self-leveling technology is a kind of ground construction technology, and the floor material under liquid condition is scattered to after ground automatically auxiliary
Trickling, liquid automatically look on ground low-lying after and filled and led up, finally full wafer ground is trickled into as minute surface smooth after the most quiet
Only, condensation cure, whole process does not relies on manpower and criticizes and scrape.Current common gravity flow flat ground material one is epoxy flooring coating,
In addition to relatively costly, often occur shrinkage cavity, piebaldism, decorative pattern, aberration, loose colour, variable color, show-through, working up, turn white, wire drawing, unglazed, glue
Fall, stickness, play the quality problems such as oil, Pericarpium Citri Reticulatae.Two is self-leveling cement earth material, and main material is ordinary portland cement, high-strength water
The additional kinds of surface coagent such as mud, portland cement and dispersed latex powder etc., relative cost is higher, its construction time to base
Layer surface processes and requires higher, aqueous many or few all directly affects Self-leveling quality, surface dusting, aliquation, aberration etc. often occurs
Quality defect, it is common that for ground decoration base treatment, other ornament materials are done on surface again, such as patch floor tile, lay wood
Plate, do floor paint etc..Three is gypsum self-leveling earth material, and main material is Gypsum Fibrosum and quartz sand, and Gypsum Fibrosum is fabulous gravity flow
Material, forms semi-hydrated gypsum in general and just has this feature, but Gypsum Fibrosum is met water i.e. powder and resists after dihydrate gypsum only calcination
The characteristic that Compressive Strength is low, significantly limit its range of application, often needs to add in Gypsum Fibrosum to help to play waterproof effect
Agent, causes production cost higher.Four is the Gypsum Fibrosum that gypsum self-leveling earth material is typically only capable to use single kind, such as fluorite
Cream, desulfurated plaster, the one in titanium gypsum.Five is that auto-flowing floor needs first to look for by cement mortar in preparation process
Flat, pour into a mould gravity flow flat ground material the most again, preparation process is cumbersome, the longest.
