Technical field
The invention belongs to chemical products preparing technical field, particularly to a kind of preparing super fine magnesium hydroxide by wet method slurry Method.
Background technology
Magnesium hydroxide has high activity, high absorption capacity, stronger shock-absorbing capacity due to it, uses safe and corrosion-free Property, many special performances such as nontoxic, its raw material rich reserves in addition, it is widely studied in nearly recent decades.Magnesium hydroxide according to Form and purposes are divided into filter cake shape, powdery and pulp-like three major types, and three can phase co-conversion.Magnesium hydroxide therein Slurry production process flow process is simple, operates safety, non-environmental-pollution and enjoy high praise.The preparation method of magnesium hydroxide slurry a few days ago Mainly include magnesium oxide aquation method, the salt sedimentation method, shepardite waterproof pulverization method.
The present situation of magnesium hydroxide slurry, the U.S. and Japan are that the use of magnesium hydroxide consumes big country, and its application is main It is used in environmental protection aspect.This is because magnesium hydroxide can be widely applied to acid waste water neutralization, heavy metal removing, water process and cigarette In road gas, the aspect, the particularly developed country such as the U.S., Japan such as desulfurization quickly grow.
1, shepardite is a kind of industrial mineral being mainly composed of magnesium hydroxide, can be used as after superfine grinding is processed Low cigarette, nontoxic fire-retardant filler;Existing scientific and technical literature is recorded: use medium stirring mill that shepardite carries out Wet-type super-fine disintegrating real Testing room and commerical test research, the factor such as grinding aid kind and consumption, pulp density, rotor speed that have studied is to product granularity Impact.Shortcoming is to use expensive zirconium oxide microballoons as abrasive media to realize the refinement of magnesium hydroxide granularity, so not With adding cost prepared by magnesium hydroxide in degree.2, the patent of invention of Application No. 200410005164.x discloses one Wet method prepares shepardite or the method for sintered magnesia micropowder, is the raw material brucite powder with 1000 weight fineness >=100 mesh Or sintering oxidation magnesium powder add the molecular weight of 10~80 weight be 1500~4500 polyacrylic acid or its salt, alkyl benzene sulphonate or its One in one in salt, polyether phosphate, the fatty acid of 5~70 weight or its salt, phosphate ester or its salt, 600~2000 The water of weight, in grinding machine, pulverizes 1h at 50~90 DEG C, slurry has good mobility as milk, does not condenses, no between granule Bonding, does not need to separate and convection drying i.e. obtains powder product, mean diameter < 5 μm, has hydrophobic performance and float in water.The highest Crush efficiency, easy technological process is the feature that this technology is prominent with obtaining high-quality superfine product.Shortcoming is institute The magnesium oxide used is to use the light-burned magnesium hydroxide of more than 800 DEG C.
3, the patent of invention of Application No. 200810300453.0 discloses a kind of sodium-hydroxide method and prepares high pure and ultra-fine hydrogen The technique of magnesium oxide, uses decomposition of crystal seed method, by mixing in purified brine and magnesium hydroxide crystal seed addition reaction tank, 60~80 DEG C Insulation, then sodium hydroxide solution is added reaction tank carries out precipitation, crystallization ageing, reaction extracts magnesium hydroxide after terminating Slurry filtration, washing, filter cake drying, pulverizing, obtain magnesium hydroxide crystal product.Shortcoming is to need the ageing of long period, Operate complex, and the filtrate produced does not reuses.
4, the method that the patent of invention of Application No. 01127343.7 discloses One-step production magnesium hydroxide: it will contain The salt of magnesium chloride mixes with the ratio that mol ratio is 1: 1.3-2.0 of free ammonia according to magnesium chloride with ammonia, and makes mixture The environment of 45 degree of-90 degree Celsius reacts 5-30 minute, reactant liquor is consolidated after filtering, wash, be dried, pulverizing Body magnesium hydroxide.Shortcoming is that the method uses ammonia to participate in producing as alkali liquor, pollution environment, output ammonium chloride garbage, and And the dispersive property of this product is poor, final products need through being dried, pulverization process.
5, the patent of invention of Application No. 200610146040.2 discloses a kind of shepardite wet method and prepares ultra-fine hydroxide The method of magnesium powder: first existing is that raw material ball milling 36 after 450 DEG C-700 DEG C calcinings, addition dehydrated alcohol+water is little by brucite powder Time, 120 DEG C be dried, pulverizing prepare ultrafine magnesium hydroxide powder.Shortcoming is that the method uses dehydrated alcohol to participate in producing as solvent, There is potential safety hazard, and the process time of this product is longer, final products need through being dried, pulverization process.
In sum, this area be easily isolated in the urgent need to a kind of simple operating steps, product, solid content high and right Eco-friendly magnesium hydroxide slurries preparation method for material.
