More particularly, the invention relates to an extender which uses spent molasses condensate (''SMC'') as the grinding efficiency reinforcing agent for the polyhydric alcohol selected from dibasic alcohol, glycerin or the mixture thereof, wherein the SMC is the condensed residue generated after the evaporation of the raw waste water obtained from distillation of beet or sugarcane molasses.
Description
Technical field
The present invention relates to improve the mill efficiency of matrix material, the method that particularly relates to novel composition and be used to grind cement clinker, slag, flyash or its mixture, wherein the waste molasses enriched material is used to increase and fills (extend) mill efficiency toughener based on water-soluble polyol.
Background technology
The term used as this section " additive " is meant before the cement clinker that contains or do not contain the slag substitute grinds to form the process of finished cement or the chemical reagent that adds in the process; And term " admixture (admixture) " be meant with cement, aggregate (as, sand and/or rubble) but and the water combination with the reagent of the cementing compositions (for example mortar or concrete) of generation hydration.
Known, adopt other byproduct in molasses and the sugared production process as the admixture in the additive in the manufacture of cement and mortar and the concrete to change one or more performances.
At United States Patent (USP) 2,311, in 288, people such as Booth disclose the use of " thick fermentation residue ", and described " thick fermentation residue " is that " in alcohol or some production of alcoholic drinks that fermentability carbohydrate raw material fermentation (comprising " fermentations of red molasses ") is back " obtains.Referring to Col.1, II.26-36.In process of lapping, in cement clinker (clinker), add " the molasses residue of evaporation " as dry-matter to increase the plasticity-of cement.Referring to Col.1, II.13-15, page 2.
At United States Patent (USP) 2,435, in 594, MacPherson points out, removes alcohol resulting " remaining solid of the sulfite waste lye of fermentation " by fermentation or distillation remaining solid and can be used for maturing.

Embodiment
Except as otherwise noted, all this paper describe or claimed component percentages should be according to the total weight of composition, and relative content or ratio should calculate according to the weight of described component.
Term used herein " cement " is meant and mainly is meant silicate (Portland) cement, its as building trade used be meant by pulverize or common grind (intergrinding) but the cement of the hydration that cement clinker is produced, described cement clinker is made up of Calucium Silicate powder, and the calcium sulfate that contains one or more forms usually is as common interground addition.
" bonding (cementitious) " but thereby material is itself has the hydraulic characteristic or hydration cohesiveness is solidified and the hardened material in the presence of water.Silicate cement can be hydrated cementitiously comprised and so-called volcanic ash can be comprised, described volcanic ash is siliceous or silica-aluminum materials, it does not almost have or does not have cementing value (promptly, as tackiness agent), but the calcium hydroxide generation chemical reaction that the volcanic ash of form in small, broken bits can be discharged with the silicate cement hydration in the presence of water forms the material with bonding characteristic.Referring to as, Dodson, V., Concrete Admixtures (Von Nostrand Reinhold, New York 1990), the 159th page.Some known volcanic ash are diatomite, Wingdale, clay (as, metakaolin), shale, flyash, silica flour and blast-furnace slag.
Because some granulated blast furnace slag and high-calcium fly ass through grinding not only has volcanic ash character but also has cementing property, so term used herein " matrix material " is meant silicate cement and granulated blast furnace slag, flyash or its mixture, and gypsum, grind jointly in the process that produces cement at cement clinker usually and mix a small amount of gypsum.
It is believed that, can adopt any known shredder type, comprise ball mill and tumbling mill (or roller mill (roller mills)).Usually use ball mill, wherein cement clinker together with the matrix material (slag, flyash, other volcanic ash) that replenishes but common the grinding with the finished cement of producing hydration (as, silicate cement).Can use the grinding machine (for example roller rolling machine) with roll, wherein roller rotates on circular table, and cement clinker, slag and/or flyash are crushed on this circular table.The roller mill of other type adopts two or more rollers of clipping together, then by vertically unloading material with its pulverizing between the roller of clamping.Therefore, but method and composition of the present invention can use being used for grinding cement, slag and/or flyash ball mill and roller mill with the cement granules of producing hydration.

Another kind of exemplary water-soluble polyol comprises that known conventional is used as the glycerine of cement efficient enhancement additive.This type of glycerine can be selected from two-, three-and four glycerine with and composition thereof.
The further exemplary water-soluble polyol of available comprises the adulterant of dibasic alcohol and glycerine among the present invention.
Preferably, based on the weight of (multiple) component, the ratio of the molasses residue of water-soluble polyol component and component (B) was at 20: 80 umbers to 50: between 50 umbers.
Most preferably, described water-soluble polyol is glycol ether (DIEG), and based on the weight of component, DIEG and such as the ratio (DIEG: the SMC portion rate) between 70: 30 to 80: 20 of the molasses residue of waste molasses enriched material (" SMC ").
(Spent Molasses Concentrates SMC) obtains in the beet or the cane molasses course of processing waste molasses enriched material.Described SMC obtains as the waste product after beet or the cane molasses distillation (subordinate phase), and described beet or sucrose molasses are the byproducts in sugar refinery (fs) of processing beet or sugarcane.In the fs, beet or sugarcane are shredded and are torn up basically, combine with water and lime, and heating to be obtaining clarifying juice or syrup, and then obtain sugar crystal thus.Some stages (removing sugar crystal during this period) later, remaining molasses liquid is sold to brewery's (subordinate phase of processing therein).In this subordinate phase, in molasses, add yeast and water and enter fermentation unit and be converted into alcohol (as, ethanol) with the sugar that will exist in the molasses.Use distillation tower to remove alcohol.Remove ethanol remaining bottom refuse (solid) and liquid condensate (raw wastewater).The liquid condensate that this concentration be can be about 10Brix is stored in the storage tank and pumps in one or more placed in-line vaporizers, thus with the condensation product recycle back to producing in (process) (being used for further distillation).After twice or three times or more times distillation circulation, remaining liquid substance is called the liquid concentrate of " waste molasses enriched material " (" SMC ") in the vaporizer for this paper.
SMC is generally dark brown black, viscous liquid, and proportion is the 1.05-1.40 kg/liter, and water-soluble.The waste molasses enriched material can be from Fermpro, 102-1002, Blok A, Pusat Dagangan Phileo damansara1, No.9, Jalan 16/11, (factory is positioned at Kawasan PerindustrianChuping to Off Jalan Damansara, 021450Kangar, Perlis, Malaysia) commercially available.SMC is considered to contain have an appointment 50% water, 20% natural gum, wax/carbohydrate/xylogen of 16%, 10% inorganic materials, 3% protein and 1% organic acid usually.
It is believed that many countries all can obtain SMC, wherein liquid molasses enriched material is to obtain from the distillation of beet or cane molasses as the residue byproduct, and can various names be used for multiple use and sells (for example, (liquid) molasses fermented refuse and other).
