Abstract
The invention relates to a production method of aluminum sulfate used for paper making, wherein the product made is the inorganic retention aid commonly used in paper making industry. The method is used mainly when in acid making news paper containing mechanical wood pulp and is helpful to certain degree to precipitation of fine components and water filtration of pulp and the like. Besides, the method also has the effects of adjusting the pH value of a system, and clearing 'anionic trash' in the system. In use, the cation in the aluminum sulfate is absorbed on the surface of fiber and fine components to change the characteristic of surface charge of fiber and fine components, and affect absorption of other cation chemical auxiliaries on fiber. The main ingredients of the aluminum sulfate mainly include: water, solid aluminum sulfate, sodium hypochlorite, fatty acid amide, polyethylene wax atoleine, oxidized polyethylene, bi-isooctyl-thioglycolate, thiophanate and aluminium stearate.
Description
Affiliated technical field:
Product of the present invention belongs to the chemical industry field of papermaking.
Background technology:
The main component of product of the present invention is an aluminum sulfate.The inorganic retention agent that uses on paper industry is more: aluminum sulfate (being commonly referred to as paper-makers' alum), polyaluminium sulfate, aluminium polychloride, bentonite and cataloid etc. are arranged.According to the difference of paper kind, select different inorganic retention agents for use.Aluminum sulfate then is the most frequently used inorganic retention agent, especially when containing machine wood pulp newsprint acid papermaking, use, it has certain help to keeping with the drainage of paper pulp etc. of tiny component, also has effects such as " anionic trashes " in the pH value, scavenge system of regulating system in addition.The operation principle of aluminum sulfate is adsorbed on its usefulness of performance on paper stock fiber and the tiny component by its CATION, CATION in the aluminum sulfate just is adsorbed on the surface of fiber and tiny component, change the surface charge characteristic of fiber and tiny component, and other cationic chemical auxiliary agent absorption on fiber exerted an influence, thereby improve the one way retention of filler, and the filer content in the minimizing plain boiled water, reduce cost thereby reducing runs off, can also reduce the concentration and the ash content of approach flow, prolong the life-span of forming net, and make the smoothness of page, opacity and folding strength improve.Aluminum sulfate gives over to the usefulness except helping, and also has certain helping and filters and flocculation, thereby invented this product.
Summary of the invention:
The present invention relates to a kind of inorganic retention agent aluminum sulfate and production method thereof.The prescription of this retention agent is: 70 parts in water, 20 parts in solid sulphuric acid aluminium, 2 parts of clorox, 2 parts of fatty acid amides, 1 part of Tissuemat E atoleine, 1 part of oxidic polyethylene, 2 parts of dimercapto 2-ethyl hexyl ethanoate dioctyltins, 1 part of thiophanate, 1 part of aluminum stearate.(above raw material only provides proportioning, can determine the weight of each formula material during production according to the size of chemical reaction kettle)
The specific embodiment:
The first step: add 70 parts of entry in chemical reaction kettle, begin after being warming up to 50 ℃ to stir, the rotating speed of stirring is 45 rev/mins, adds 20 parts in solid sulphuric acid aluminium while stirring, treats that aluminum sulfate all after the dissolving, adds 2 parts of clorox, reacts 1 hour.Second step: add 2 parts of fatty acid amides, 1 part of Tissuemat E atoleine, 1 part of oxidic polyethylene, stir and be warming up to 65 ℃, reacted 2 hours.The 3rd step: add 2 parts of dimercapto 2-ethyl hexyl ethanoate dioctyltins, 1 part of thiophanate, 1 part of aluminum stearate, keep 65 ℃, continuation is stirred, and reacts to obtain finished product in 0.5 hour.The cooling blowing is stand-by.
