Abstract
The present invention relates to sticking paste for guard rings of steel paws of prebaked anodes in an aluminum cell. The present invention has the weight percentage composition of ingredients that 57 to 67% of recovered waste anode powder, 30 to 38% of water, 1 to 3% of polyacrylamide and 2 to 5% of powdery coal tar; when the recovered waste anode powder, the water and the powdery coal tar are evenly mixed, the polyacrylamide is added, and the sticking paste can be made when stirred evenly again. The sticking paste of the present invention, which uses the recovered waste anode powder, has the advantages of low cost, simple production process, production in normal temperature, convenient operation, no environment pollution, good cohesiveness in normal temperature, which solves the problem that the sticking paste can not preserve and use in the normal temperature, good application performance, easy construction and low labor intensity of production.
Description
Technical field
The present invention relates to a kind of prebaked anode in aluminium cell steel claw protection ring bonding paste, be used to protect prebaked anode in aluminium cell steel pawl.
Background technology
Prebaked anode in aluminium cell does not weather and prolongs the anode working cycle for guaranteeing anode steel jaw aborning, needs with carbon protective ring and bonding paste steel is grabbed to protect, because the steel pawl recycles aborning, guard ring bonding paste consumption is big.Existing bonding paste prescription is made up of coal-tar pitch, carbolineum, after-smithing petroleum coke, earlier with the high-temperature calcination of raw petroleum coke process, be ground into the particulate material of different diameter again, simultaneously coal-tar pitch high temperature melt and liquid carbolineum are mixed together, between 110 ℃-130 ℃, mix and pinch into paste, feed steam insulation and come into operation then, production cost height (about 1350 yuan/ton of cost), environmental pollution are serious, use labour intensity big.On the other hand, having a large amount of carbon dusts to reclaim during Aluminium Electrolysis anode scrap cleaning is pulverized, drain because of can not the Returning process use being taken as rubbish, also is a very big waste.
Summary of the invention
The object of the present invention is to provide a kind of prebaked anode in aluminium cell steel claw protection ring bonding paste of brand-new composition, cost is low, and is pollution-free, and application performance is good, and productive labor intensity is little.
Prebaked anode in aluminium cell steel claw protection ring bonding paste of the present invention, its ingredients by weight percentage composition is:
Anode scrap reclaims powder 57～67%
Water 30～38%
Polyacrylamide 1～3%
Powdery coal-tar pitch 2～5%.
Best group becomes:
Anode scrap reclaims powder 62.4%
Water 32%
Polyacrylamide 1.85%
Powdery coal-tar pitch 3.75%.
The preparation method: under the normal temperature, anode scrap is reclaimed powder, powdery coal-tar pitch and water stir, add polyacrylamide then, restir evenly gets final product.
Polyacrylamide is that a kind of flocculation agent has good wetting ability and cohesiveness; to reclaim powder and the water back that stirs adds polyacrylamide and makes thickener; substitute the requirement that original bonding paste can satisfy the protection anode steel jaw fully; compare with existing bonding paste, bonding paste of the present invention has following beneficial effect:
(1) cost is low.Former in 1350 yuan/ton of bonding paste production costs, and bonding paste of the present invention has utilized anode scrap to reclaim powder, only 700 yuan/ton of production costs have tangible cost advantage, can significantly reduce the anode assembly cost, can make the anode assembly cost reduce about 12%.
(2) production technique is simple, environmentally safe.Originally bonding paste production need will have a cover corresponding production equipment and a technical qualification complicated operation to calcining petroleum coke with to the coal-tar pitch thawing of heating.The obnoxious flavour that produces in the production pollutes and injures environment and personnel.Bonding paste of the present invention adopts the waste material that produces in the adopting electrolysis residual pole cleaning, equipment is single, technology is simple, carry out under the normal temperature, easy handling adopts and to make the polyacrylamide that water purification agent uses and be binding agent, coal-tar pitch, carbolineum have been eliminated fully to environment and operator's pollution and injury, the powder that gathers dust of anode scrap fragmentation has simultaneously obtained recycling, has reduced the industrial refuse discharging, has realized cleaner production.
(3) adopt polyacrylamide as binding agent, novel bonding is stuck with paste had good cohesiveness at normal temperatures, solved the difficult problem that existing bonding paste can't be preserved use at normal temperatures, application performance is good, and it is convenient to construct, and productive labor intensity is little.
