Abstract
The invention discloses a kind of aluminium polychloride and its production method, which belongs to chemical industry field of papermaking, and producing the raw material that the product uses includes: gibbsite, technical-grade hydrochloric acid, tap water, calcium aluminate powder.The preparation method simple process, product is mainly used for water purification and papermaking, inorganic retention agent, sizing agent are mainly used as in papermaking, it is glued using aluminium polychloride, the retention of slurry, filtrating aid function significantly improve, it can be effectively facilitated flocculation, sizing, in addition to fracture length, all other indexs improve paper performance to some extent.
Description
Technical field:
Product of the present invention belongs to chemical field more particularly to a kind of aluminium polychloride.
Background technique:
Aluminium polychloride is the biggish flocculant of market sales volume, has the trend for gradually replacing traditional flocculant, production polymerization chlorine
The raw material for changing aluminium mainly has two major classes: one kind is aluminum-containing mineral, including bauxite (gibbsite, boehmite, a hydraulic aluminium
Stone), clay, kaolin, alunite etc.；Another kind of is other aluminum-containing raw materials, including metallic aluminium, aluminium scrap bits, grey aluminium, hydroxide
Aluminium, alchlor, gangue, flyash etc..Only using aluminium ingot, aluminium skimmings, aluminium hydroxide as raw material and with aluminum sulfate, al dichloride
Purer aluminium polychloride product can be just produced for raw material, but production cost will be higher by several times.When requiring less high,
Production aluminium polychloride mainly uses clay pit, kaolin ore and bauxite for raw material, produces aluminium polychloride product.It polymerize chlorine
That changes aluminium is mainly used for water purification and papermaking, and inorganic retention agent, sizing agent are mainly used as in papermaking, is applied using aluminium polychloride
Glue, the retention of slurry, filtrating aid function significantly improve, and can be effectively facilitated flocculation, sizing, and paper performance is other in addition to fracture length
Indices improve to some extent.
Summary of the invention:
The present invention relates to a kind of methods using kaolin production typical zolymerization aluminium chloride, produce the raw material packet that the product uses
It includes: gibbsite, technical-grade hydrochloric acid, tap water, calcium aluminate powder.
The present invention can be achieved through the following technical solutions:
(1) reaction tank is sent into after being sent into formula ratio gibbsite roaster calcination activation 2-2.5 hours；
(2) tap water and technical-grade hydrochloric acid are added in reaction tank, gibbsite: tap water: technical-grade hydrochloric acid=1.6-1.8:
2.5-2.7:4-4.2, turn on agitator stirring, warming while stirring no longer heat up when reaching 80-85 DEG C, react 1.5-
1.7 hour；
(3) temperature is dropped to 65-70 DEG C, puts into calcium aluminate powder, the weight of calcium aluminate powder and the weight of gibbsite while stirring
Than after being stirred to react 2.5-3.0 hours, suitable tap water is added for 0.8:1, polyaluminium aluminium content is adjusted at 20%,
Stop stirring, cooling down is got product.
Preferably, the aluminum content of the gibbsite is 35%.
Preferably, the purity of the calcium aluminate powder is 60%.
The beneficial effects of the present invention are: a kind of aluminium polychloride and its production method are provided, preparation method technique letter
Single, product is mainly used for water purification and papermaking, inorganic retention agent, sizing agent is mainly used as in papermaking, uses polyaluminium
Aluminium sizing, the retention of slurry, filtrating aid function significantly improve, and can be effectively facilitated flocculation, sizing, paper performance in addition to fracture length,
All other indexs improve to some extent.
