Abstract
The invention relates to a method for preparing a modified active carbon acidified water material by a dry method. The method comprises the steps of uniformly mixing active carbon with solid weak acid according to a ratio to obtain a mixture, putting the mixture into a closed container, heating the closed container put in a drying box for 4-8 hours at the temperature of 60-150 DEG C, and then cooling to obtain the modified active carbon acidified water material. The modified active carbon acidified water material can perform weak acidification on running water for bathing health protection, and has the effects of skin caring, sterilization and disinfection. According to the method, the preparation technology is simple, waste and pollution are avoided, and the environment-friendly effect and the good market prospect are achieved.
Description
Technical field
Material of the present invention belongs to field of material preparation, is specifically related to a kind of method of dry process modified activated carbon acidifying water material.
Background technology
Scientific research finds, at the mankind's skin surface, has one deck protected acidic film, and it is by covering the moisture of skin surface and the mixture of composition.Maintaining the acid-base value of skin within the scope of faintly acid, is the key of improving looks.Current running water and drinking water are all alkalescent, can not adapt to the requirement of beauty and skin care health care, therefore, how to prepare slightly acidic water in order to have improved looks into critical problem.To the development early start of slightly acidic water, the latter half eighties 20th century, Japan drops into a large amount of human and material resources slightly acidic water is studied, and they utilize the method for brine electrolysis to develop the electrolyzed water machine of producing slightly acidic water, introduce to the market.But due to existing brine electrolysis, to prepare weakly acidic equipment complicated, and cost is expensive, high energy consumption, the drawbacks limit such as life cycle is short universal the and development of this technology.
Under this background condition, this seminar had once proposed " a kind of modified activated carbon acidifying water material and preparation method thereof (CN 201210204483.8) " patent of invention innovatively in June, 2012, the activated carbon granule that this employing " wet method " modification technology makes, the pH value of running water can be adjusted to 4.0-6.0, can substantially meet the standard-required of shower after shave lotion.But what this patented technology adopted is a kind of " wet method " technique, specifically activated carbon granule is first immersed in certain density tartaric acid solution, finally also will unnecessary acid solution be removed through the method for suction filtration, the problem that this " wet method " technique is brought is all can produce many waste acid liquors in immersion and suction filtration process.The present invention adopts " dry method " technology, the ratio of active carbon and tartaric acid accurately can be controlled, tartaric acid all can be adsorbed in the middle of the micropore of active carbon, generation without any waste liquid and waste gas, further simplify technique, saved cost, without waste, pollution-free, novelty and novelty are very remarkable.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, a kind of method of dry process modified activated carbon acidifying water material is provided.The present invention mixes with solid weak acid and active carbon, in anhydrous environment, heat, make modified activated carbon acidifying water material, running water becomes faintly acid during by this material, and various poisonous and harmful substances in the adsorbable removal running water of this material, the weak acid molecule that simultaneously can continuous release goes out to have skin-protection and health-care effect, by regulating the pH value of water to faintly acid, plays health-care and skin-care effect.Preparation method provided by the invention is simple, and raw material is easy to get, with low cost, pollution-free, without waste, the complete environmental protection of material of preparing.
For achieving the above object, the present invention adopts following technical scheme:
A method for dry process modified activated carbon acidifying water material, after active carbon is mixed in proportion with solid weak acid, airtight, be placed in drying box and heat, cooling rear taking-up makes a kind of modified activated carbon acidifying water material.
Described whole preparation process is carried out under the condition of bone dry.
Described active carbon is particle charcoal, and described solid weak acid comprises malic acid, citric acid.
The mass ratio of active carbon and solid acid is 2:1 ~ 10:1.
The temperature of described drying box is 60 ~ 150 ℃, and the heat time is 4 ~ 7 hours.
The slightly acidic water material that a kind of preparation method as above makes.
Beneficial effect of the present invention:
It is raw material that active carbon and solid weak acid (tartaric acid is as main) are take in the present invention, make full use of the extremely strong adsorptivity of active carbon, through weak acid-treated mode, prepare a kind of novel slightly acidic water material, for " wet method " technique, " dry method " technique does not exist soaks and suction filtration process, also just can not produce many waste acid liquors, have method simple, raw material is easy to get, with low cost, and the feature such as can be recycled.
The specific embodiment
The present invention further illustrates the present invention with the following example, but protection scope of the present invention is not limited to the following example.
After proper amount of active carbon is mixed with solid weak acid, the airtight insulating box of putting into heats, and takes out the cooling slightly acidic water material that is.
Below in conjunction with specific embodiment, content of the present invention is specifically described:
Embodiment 1
Utilize weak acid modification acidifying active carbon to prepare slightly acidic water material, its raw material is as follows: cocoanut active charcoal particle, L MALIC ACID.
Preparation process is:
20g cocoanut active charcoal is mixed with the L MALIC ACID of 4g, stir evenly, it is airtight, be placed in temperature and be the heater insulation 7h of 70 ℃, take out sample, be cooled to room temperature, obtain apple acid slightly acidic water material.
Simulation daily life environment for use, above-mentioned slightly acidic water material is packed in special-purpose filter core, in water speed, be under the water tap of 1550mL/min, to cross water, it is 86min that pH4.5～6.0 change duration, and the volume that calculates the slightly acidic water (pH4.5～6.5) that can produce is 133L.
Embodiment 2
Utilize weak acid modification acidifying active carbon to prepare slightly acidic water material, its raw material is as follows: cocoanut active charcoal particle, citric acid.
Preparation process is:
20g cocoanut active charcoal is mixed with the citric acid of 5g, stir evenly, it is airtight, be placed in temperature and be the heater insulation 6h of 110 ℃, take out sample most, be cooled to room temperature, obtain lemon acid slightly acidic water material.
Simulation daily life environment for use, above-mentioned slightly acidic water material is packed in special-purpose filter core, in water speed, be under the water tap of 1500mL/min, to cross water, it is 98min that pH4.5～6.5 change duration, and the volume that calculates the slightly acidic water (pH4.5～6.5) that can produce is 147L.
