Abstract
The invention discloses graphite powder used in an aluminum electrolysis anode aluminum guide rod casting process and relates to graphite powder capable of being stably dispersed in water. The graphite powder is characterized by being modified graphite powder added with a dispersing agent. According to the graphite powder used in the aluminum electrolysis anode aluminum guide rod casting process, a working environment can be effectively improved, the production cost is reduced, and the operation safety is improved.
Description
Technical field
The Graphite Powder 99 that a kind of aluminium anode aluminium guide bar casting cycle uses, but relate to the Graphite Powder 99 of a kind of stable dispersion in water.
Background technology
At present, the anode that aluminium electrolytic industry adopts all is carbon anode, on carbon anode, need carry out the aluminium guide bar casting before the groove, very important in carrying out an aluminium guide bar casting cycle link is " dipping in graphite ", the purpose of " dipping in graphite " makes steel pawl head surface adhere to one deck equadag coating exactly, be difficult for during casting causing splashing, and when residual anode pressure-disengaging, make the phosphorus pig iron be easy to separate with the steel pawl.
The Graphite Powder 99 that adopts in the actual production is special, and granularity is very thin, and general solvent is difficult to dissolving, normally adopts kerosene to come dispersion liquid, this Graphite Powder 99 price comparison costliness, and the price of kerosene has so just caused the raising of production cost also than higher in addition.And, use kerosene, under production environment, also be easy to generate danger, also producing niff influences workers'health.
Summary of the invention
Purpose of the present invention is exactly the deficiency that exists at above-mentioned prior art, and a kind of effective Graphite Powder 99 that improves Working environment, reduces production costs, improves the aluminium anode aluminium guide bar casting cycle use of processing safety is provided.
The objective of the invention is to be achieved through the following technical solutions.
The Graphite Powder 99 that a kind of aluminium anode aluminium guide bar casting cycle uses is characterized in that this Graphite Powder 99 is for adding the modified graphite powder of dispersion agent.
The Graphite Powder 99 that a kind of aluminium anode aluminium guide bar casting cycle of the present invention uses is characterized in that the Graphite Powder 99 granularity is less than 0.297mm.
But the Graphite Powder 99 of a kind of stable dispersion of the present invention in water, the addition that it is characterized in that its dispersion agent be Graphite Powder 99 weight 0.1% ~ 30%
The Graphite Powder 99 that a kind of aluminium anode aluminium guide bar casting cycle of the present invention uses is characterized in that its dispersion agent is for being selected from linear alkylbenzene sulphonic acid (LAS), polyoxyethylenated alcohol sodium sulfate (AES), AESA (AESA), sodium laurylsulfate (K12 or SDS), Nonyl pheno (10) ether (TX-10), paregal O, diglycollic amide (6501) stearic acid monoglyceride, sulfonated lignin, heavy alkylbenzene sulfonate, alkylsulfonate (sulfonated petro-leum), dispersing agent NNO, dispersing agent MF, alkyl, polyether (PO-EO multipolymer), the mixing of one or more in aliphatic alcohol polyethenoxy (3) ether (AEO-3).
The Graphite Powder 99 that a kind of aluminium anode aluminium guide bar casting cycle of the present invention uses, with mixing of common Graphite Powder 99 and one or more dispersing additives, stable dispersion is in water effectively, and the mode that can adopt spraying, brush and dip in is operated.Effectively improve and on carbon anode, carry out aluminium guide bar cast aluminum guide rod casting cycle Working environment when " dipping in graphite " before the groove, reduced production cost, improved processing safety.
