Abstract
The invention provides a diluting agent prepared with paper pulp waste, which consists of the following components by weight percent: 65-80 percent of lignin sulfonate, 2-8 percent of total iron, no more than 3 percent of calcium sulfate, no more than 4 percent of water-insoluble substances and water. The main component of the diluting agent prepared with the paper pulp waste is the lignin sulfonate. The diluting agent has high molecular weight, realizes the recycling of resources, contains no hexavalent chromium, has no toxicity, and is not harmful to human beings or the environment.
Description
Technical field
The present invention relates to the paper pulp waste process field, be specifically related to a kind of thinner that is prepared from by paper pulp waste.
Background technology
The paper industry environmental pollution is heavier, in paper-making process, xylogen in the plant at high temperature passes through various processes such as chemical pulping, variation has taken place in its structure, netted macromole is degraded, and has part xylogen condenses to form, and is the fragment stripping that varies in size, dissolved also has hemicellulose etc. simultaneously, becomes the main component of pulping waste liquor.
The paper pulp waste that contains a large amount of xylogen is seriously polluted, and is very harmful, must carry out the comprehensive regulation to paper pulp waste, and administer focus on reclaiming xylogen in the waste liquid, and xylogen is efficiently utilized as a kind of resource.Generally be in paper pulp waste, to add chromium class catalyzer, can make chromium lignin sulfonate, chromium lignin sulfonate is existing to fall the dehydration effect, diluting effect is arranged again, also having anti-salt, high temperature resistance, characteristics that compatibleness is good simultaneously, is a kind of anti-salt, anticalcium and the strong thinner of temperature resistance ability, is widely used in fresh water, seawater and saturated saltwater mud, various calcium-treated muds and ultra deep well mud have effectively stabilizing borehole and make the mud viscosity reduction, fall the effect of cutting.
But the hexavalent chromium in the chromium class catalyzer has severe toxicity, easily is absorbed after the human body contact, and carcinogenic danger is arranged, and environment is had lasting danger, so the usage quantity of the thinner of chromium lignin sulfonate reduces year by year.
Summary of the invention
The problem that the present invention solves is to provide a kind of thinner by the paper pulp waste preparation, and main component is sulfonated lignin, does not have toxicity, can not work the mischief to human body and environment during use.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of thinner by the paper pulp waste preparation is become to be grouped into by following weight percent:
Sulfonated lignin: 65%～80%;
Full iron: 2%～8%;
Calcium sulfate: 1%≤3%;
Surplus: moisture.
As preferably, the weight percent of described sulfonated lignin is 75%～80%.
As preferably, the heavy per-cent of described full iron is 2%～5%.
As preferably, described thinner is prepared from by following method:
Sulfuric acid, ferrous sulfate and hydrogen peroxide added in the entry mix, the preparation displacer;
Described displacer is added in the tackiness agent, obtain a defective material after the reaction, described tackiness agent is the concentrated solution of paper pulp waste;
Potassium permanganate is mixed the preparation potassium permanganate solution with water;
Described potassium permanganate solution is mixed with a described defective material, obtain two defective materials after the reaction;
The pH value of described two defective materials is transferred to 2.5～3.0.
Thinner main component by the paper pulp waste preparation provided by the invention is sulfonated lignin, the molecular weight height, realized the recycling of resource, when this thinner is used for drilling well, result of use is remarkable, also has characteristics such as high temperature resistant, nontoxic, no burn into compatibleness is strong simultaneously, does not have toxicity, safe in utilization, human body and environment are safe from harm.
Embodiment
In order further to understand the present invention, below in conjunction with embodiment the preferred embodiment of the invention is described, but should be appreciated that these describe just to further specifying the features and advantages of the present invention, rather than to the restriction of claim of the present invention.
The present invention handles paper pulp waste, does not use chromium class catalyzer in treating processes, and preparing with sulfonated lignin is the not chromyl thinner of main component.Should become to be grouped into by following weight percent by the thinner of paper pulp waste preparation: sulfonated lignin: 65%～80%; Full iron: 2%～8%; Calcium sulfate: 1%≤3%; Surplus: moisture.As preferably, the weight percent of sulfonated lignin is 75%～80%, and the weight percent of full iron is 2%～5%.
Thinner provided by the invention is prepared by paper pulp waste by following method:
The preparation displacer is standby earlier, earlier sulfuric acid is added in the entry during preparation, and then adds ferrous sulfate, in the mixed solution of sulfuric acid and ferrous sulfate, add hydrogen peroxide again, when adding hydrogen peroxide, with the pressure of 0.1Mpa～0.3Mpa hydrogen peroxide evenly is pressed in the mixed solution, stir then.
For convenient paper pulp waste is handled, reduced floor space, paper pulp waste is concentrated, the concentrated solution of paper pulp waste is called tackiness agent.Again the displacer for preparing is added in the tackiness agent and react.The volume of the displacer that adds preferably calculates according to the proportion of tackiness agent, calculation formula is the mass percent concentration of full iron in the giving money as a gift of proportion * tackiness agent * 4.1/ displacer of volume * tackiness agent of volume=tackiness agent of displacer, wherein giving money as a gift of tackiness agent is paper pulp waste and is condensed into giving money as a gift of tackiness agent, is the ratio of weight with the paper pulp waste weight of tackiness agent.Certainly for convenience calculate, also can be in advance the proportion water of tackiness agent be adjusted to the value that can be convenient to calculate,
After will calculating the quantitative displacer adding in back tackiness agent, the blended feed liquid is heated to 80 ℃～85 ℃, and insulation 15min～25min, a defective material obtained.
Also need be by the preparation potassium permanganate solution of potassium permanganate and water, calculate the quality of required potassium permanganate according to the proportion of a defective material that has made, calculation formula is the giving money as a gift of proportion * tackiness agent * 0.060345 of volume * tackiness agent of the quality=tackiness agent of potassium permanganate, and the volume of required water=potassium permanganate adds quality/0.15-potassium permanganate and adds quality.During preparation, water is heated to 40 ℃～60 ℃ earlier, adds potassium permanganate according to the amount of calculating again, then potassium permanganate is warming up to 80 ℃～85 ℃, fully stir.
Potassium permanganate solution that will preparation adds in the aforementioned defective material that obtains and reacts, if according to the formula preparation potassium permanganate solution that is provided, then whole potassium permanganate solutions are added in the defective material.Add fashionable, to under the pressure of 0.2Mpa～0.4Mpa, potassium permanganate solution evenly be pressed in the defective material, the time of being pressed into is 25min～35min, reheat to 80 ℃～85 ℃, and insulation 15min～25min, obtain two defective materials, the pH value of two defective materials is controlled at 2.5～3.0, can use NaOH to adjust.So just obtain the thinner that main component is sulfonated lignin, can make the dry powder finished product by spraying drying at last.
More than a kind of thinner by paper pulp waste preparation provided by the present invention is described in detail.Used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of claim of the present invention.
