Abstract
The invention discloses an instant polyacrylamide flocculant, which comprises the following compositions in part by weight: 1.0 part of polyacrylamide, 3.0 to 7.0 parts of composite alcohol dispersant, 0.2 to 0.9 part of anti-degrading agent and 50 to 200 parts of antifreezing agent. The instant polyacrylamide flocculant has the advantages that: the instant polyacrylamide flocculant improves the dissolution process and the storage of aqueous solution of the polyacrylamide so as to make the preparation process of the aqueous solution of the polyacrylamide simple and the storage condition of a polyacrylamide finished product loose and the storage life thereof prolonged. The instant polyacrylamide flocculant has the advantages of simple operation process and good technical and economic effects that: a. when the aqueous solution is prepared, the polyacrylamide flocculant is directly thrown into water and dissolved into qualified solution without using warm water first and performing the slow batching process, the states of fisheye-shaped granules and the like influencing the use are not generated, the field operation is convenient, and additional equipment is not arranged; b. at 50 DEG C, the instant polyacrylamide flocculant is ensured to be not degraded within 10 days and normal use is not influenced; and c. after the instant polyacrylamide flocculant is prepared into the solution, the solution is statically stored and does not freeze at 10 DEG C below zero.
Description
Technical field
The present invention relates to be in the sewage disposal to mud flocculating settling agglomerative flocculation agent, particularly be a kind of instant polyacrylamide flocculant.
Background technology
Polyacrylamide solution is to be used for sewage disposal to mud flocculating settling agglomerative.There is following defective in the configuration polyacrylamide solution in the prior art:
1. behaviour does the process complexity.The warm water (being no more than 60 ℃) that at first the polyacrylamide powder is added calculated amount 50% earlier, under agitation the polyacrylamide powder is disperseed to tremble in the entry slowly, treat to supply excess water again after it all is scattered in the water, the polyacrylamide powder is stirred to whole dissolvings.The purpose of aforesaid operations is to prevent to form in the polyacrylamide powder dissolution process agglomerate and generation " flake " phenomenon.
Described " flake " is meant that promptly occurring fork in polyacrylamide powder dissolution process gives birth to state.Its phenomenon is that polyacrylamide feed particles formation together bonded to each other center in water is that the solid skin that does not get wet wraps up one deck by the water-soluble bonding shape thing that rises, and " flake " state forms then can the dissolved again formation aqueous solution.
2. polyacrylamide solution preparation is finished the back because to be subjected to the nature border to influence the product signs of degradation very serious, and the shortening of solution storage time can only be deposited 3-5 days the most in short-term under the summer high ambient temperature, just was degraded into the waste product that can not use.The inconvenience and the discarded rate height of execute-in-place have been caused.Use winter the polyacrylamide solution must be,, be lower than very easily to freeze below 0 ℃ in envrionment temperature and cause solution discarded and influence system of subject and move if temperature uses insulation to be not good at winter on the low side at the scene in indoor storage and operation.Outdoor transport pipe when intermittently stopping using, must increase the measure of heating otherwise the processing of pipe freezeup with pretty troublesome.
Summary of the invention
The objective of the invention is to overcome the deficiency of above-mentioned technology, provide a kind of and be applicable to that on-the-spot dissolving is easy to operate, solution under (＜50 ℃) high-temperature degradation resistant, can the non-icing a kind of instant polyacrylamide flocculant of normal running under-10 ℃ of environment.
The technical scheme that solves the problems of the technologies described above is: a kind of instant polyacrylamide flocculant, described a kind of instant polyacrylamide flocculant adopt following weight proportion to form: 1.0 parts of polyacrylamides; Compound pure dispersion agent 3.0-7.0 part; Anti degradant 0.2-0.9 part; Frostproofer 50-200 part.
The invention has the beneficial effects as follows: the present invention is that the optimization that the condition of storage to the dissolution process of polyacrylamide solution and polyacrylamide solution requires improves, the making processes of polyacrylamide solution is oversimplified, made the loose renewal of condition of storage of polyacrylamide solution finished product.Operating procedure of the present invention is simple, technology and good economical benefit:
A. needn't be earlier when obtained aqueous solution with warm water, process needn't slowly feed intake.Directly drop in the water and promptly can be dissolved as qualified solution, the states such as fish-eye shaped granule that do not exert an influence and use have made things convenient for execute-in-place, do not increase equipment;
B. can guaranteeing under 50 ℃ environment did not degrade in 10 days does not influence normal use;
C. behind the wiring solution-forming under-10 ℃ environment static do not deposit freeze.
Embodiment
Below embodiments of the invention are described in further detail.
The invention provides a kind of instant polyacrylamide flocculant, described a kind of instant polyacrylamide flocculant adopts following weight proportion to form:
