Abstract
A low-carbon self-leveling floor leveling gypsum formula comprises the following components in parts by weight: 25-35 of desulfurized alpha gypsum and 25 of desulfurized beta gypsum35 to 35 portions of quartz sand, 4 to 6 portions of cement, 0.08 to 0.12 portion of cellulose ether, 0.05 to 0.15 portion of retarder, 0.06 to 0.12 portion of water reducing agent and water. Compared with the similar products at home and abroad, the raw materials of the desulfurized alpha gypsum and desulfurized beta gypsum are flue gas desulfurized gypsum, and CO in the production process2The discharge amount is lower than that of cement-based self-leveling mortar, and the environment is protected. The price is cheaper than that of the cement-based self-leveling mortar for the ground, and the engineering cost is saved. Because the desulfurized alpha gypsum and desulfurized beta gypsum are convenient to pour and are quick to set and harden, the construction period is shorter than that of cement-based self-leveling mortar, and the production efficiency is improved.
Description
Technical field
The self-flatting ground making level gypsum formula of low-carbon (LC) of the present invention belongs to mortar for building, specifically a kind of levelling gypsum of low-carbon (LC).
Background technology
In order to reduce sulfurous gas to atmospheric pollution, China's means of flue gas desulfurization of power plant transformation gets into the high speed growth stage, and 8,000,000 tons of desulfurized gesso of flue gas outputs are arranged every year approximately.
Abroad, about 55% desulfurated plaster through the various pre-treatment measures of oven dry calcining again deep processing process building materials of gypsum.China has also climbed up a new step on the preconditioning technique of desulfurized gesso of flue gas; Not only desulfurated plaster is applied in gypsum sheet material, building block and the cement setting retarder, more accumulates certain technical experience and use desulfurated plaster production powder building materials of gypsum, but utilize desulfurized gesso of flue gas; Process the self-flatting ground making level gypsum; Solve desuifurized comprehensive utilization of resources, reduce the mortar cost, the quantity discharged that reduces CO2 is section's topic that the insider is studying.
Summary of the invention
The objective of the invention is to utilize desulfurized gesso of flue gas; A kind of reduction mortar cost is provided, reduces the quantity discharged of CO2, solve a desuifurized comprehensive utilization of resources difficult problem; Increase the comfortableness and the greenness of buildings, the self-flatting ground making level gypsum of the low-carbon (LC) of developing a circular economy.
It is characterized in that:
Its prescription (by weight combination):
Desulfurization α gypsum 25-35 part
Desulfurization β gypsum 25-35 part
Silica sand 35-45 part
Cement 4-6 part
Ether of cellulose 0.08-0.12 part
Retardant 0.05-0.15 part
Water reducer 0.06-0.12 part
Water 25-35 part
More than be commercially available
Described desulfurization α gypsum is produced through hydrothermal method by desulfurized gesso of flue gas; Described desulfurization β gypsum is to be dewatered in 120 ℃～180 ℃ unsaturation vapor medium by desulfurized gesso of flue gas to form; Described retardant is a SC high-efficient retarder of building the independent research of institute of section, wherein five sodium-salt (the Na of diethylene triaminepentaacetic acid(DTPA)
5DTPA) composition accounts for more than 95%; Described ether of cellulose is hydroxyethylmethyl-cellulose ether (MHEC) or hydroxypropyl methyl cellulose ether (MHPC), and range of viscosities is in 400-600 ten thousand scopes; Described water reducer is a polycarboxylate water-reducer.
The positive effect of implementing after this technology is: with comparing of similar products at home and abroad, because the raw material of desulfurization α gypsum and desulfurization β gypsum all adopts desulfurized gesso of flue gas, the CO2 quantity discharged of production process is lower than cement-based self-leveling mortar, is beneficial to environmental protection.Price is more cheap with cement-based self-leveling mortar than ground, has practiced thrift engineering cost.Because desulfurization α gypsum and desulfurization β gypsum are built conveniently, setting and harden is very fast, so construction period is shorter than cement-based self-leveling mortar, has improved production efficiency.
