Abstract
A kind of method that the present invention relates to dry process modified activated carbon acidifying water material, mixes in proportion activated carbon and solid weak acid, loads hermetic container, cooling after being placed in drying baker 60-150 DEG C of heating 4 ~ 8 hours, can be prepared by.The modified activated carbon acidifying water material of the present invention, by low acidified for tap water for bathing health, can have effect of beauty and skin care, sterilizing.Preparation technology of the present invention is simple, without waste, pollution-free, environmental protection, has good market prospect.
Description
Technical field
The material of the present invention belongs to field of material preparation, a kind of method being specifically related to dry process modified activated carbon acidifying water material.
Background technology
Scientific research finds, the skin surface the mankind has one layer of protected acidic film, the mixture that it is made up of the moisture and oils and fats that cover skin surface.Maintain the acid-base value of skin within the scope of faintly acid, be the key improved looks.Current tap water and drinking water are all in alkalescence, it is impossible to 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 puts into substantial amounts of human and material resources and slightly acidic water has been studied, and they utilize the method for electrolysis water to develop the electrolyzed water machine producing slightly acidic water, introduce to the market.But owing to existing electrolysis water prepares weakly acidic equipment complexity, cost intensive, high energy consumption, the shortcomings such as life cycle is short limit the universal of this technology and development.
Under this background condition, this seminar once proposed " a kind of modified activated carbon acidifying water material and preparation method thereof (CN201210204483.8) " patent of invention innovatively in June, 2012, the activated carbon granule that this employing " wet method " modification technology prepares, the pH value of tap water can be regulated 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 fruit acid solution, finally also being removed by unnecessary acid solution through the method for sucking filtration, the problem that this " wet method " technique is brought is to soak and all can produce many waste acid liquors in sucking filtration process.The present invention adopts " dry method " technology, the ratio of activated carbon Yu fruit acid accurately can be controlled, fruit acid all can be adsorbed in the middle of the micropore of activated carbon, there is no the generation of any waste liquid and waste gas, further simplify technique, save cost, without waste, pollution-free, novelty and novelty are very notable.
Summary of the invention
Present invention aims to the deficiencies in the prior art, it is provided that a kind of method of dry process modified activated carbon acidifying water material.Present invention solid weak acid and activated carbon mix, anhydrous environment heats, prepare modified activated carbon acidifying water material, faintly acid is become when tap water is by this material, and various poisonous and harmful substances in this material adsorbable removal tap water, the weak acid molecule with skin-protection and health-care effect can be discharged continuously simultaneously, by the pH value of adjustment water to faintly acid, play 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 prepared.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of method of dry process modified activated carbon acidifying water material, after activated carbon and solid weak acid are mixed in proportion, airtight, it is placed in drying baker and heats, take out after cooling and namely prepare a kind of modified activated carbon acidifying water material.
Described whole preparation process carries out when being completely dried.
Described activated carbon is granule charcoal, and described solid weak acid includes malic acid, citric acid.
The mass ratio of activated carbon and solid acid is 2:1 ~ 10:1.
The temperature of described drying baker is 60 ~ 150 DEG C, and heat time heating time is 4 ~ 7 hours.
The slightly acidic water material that a kind of preparation method as above prepares.
Beneficial effects of the present invention:
The present invention based on activated carbon and solid weak acid (fruit acid) for raw material, make full use of the adsorptivity that activated carbon is extremely strong, through the mode of weak acid treatment, prepare a kind of novel slightly acidic water material, for " wet method " technique, " dry method " technique is absent from soaking and sucking filtration process, also would not producing many waste acid liquors, have method simple, raw material is easy to get, with low cost, and the feature such as can be recycled.
Detailed description of the invention
Present invention the following example further illustrates the present invention, 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, airtight oven heat of putting into, takes out cooling and is slightly acidic water material.
Below in conjunction with specific embodiment, present invention is specifically described:
Embodiment 1
Utilizing the modified acidifying activated carbon of weak acid to prepare slightly acidic water material, its raw material is as follows: cocoanut active charcoal granule, L MALIC ACID.
Preparation process is:
20g cocoanut active charcoal is mixed with the L MALIC ACID of 4g, stirs evenly, it is airtight, it is placed in the heater insulation 7h that temperature is 70 DEG C, takes out sample, be cooled to room temperature, obtain Fructus Mali pumilae acid slightly acidic water material.
Simulation daily use environment, above-mentioned slightly acidic water material is loaded in special filter element, crossing water under the water tap that water speed is 1550mL/min, it is 86min that pH4.5～6.0 change duration, and the volume calculating the slightly acidic water (pH4.5～6.5) that can produce is 133L.
Embodiment 2
Utilizing the modified acidifying activated carbon of weak acid to prepare slightly acidic water material, its raw material is as follows: cocoanut active charcoal granule, citric acid.
Preparation process is:
20g cocoanut active charcoal is mixed with the citric acid of 5g, stirs evenly, it is airtight, it is placed in the heater insulation 6h that temperature is 110 DEG C, takes out sample most, be cooled to room temperature, obtain Fructus Citri Limoniae acid slightly acidic water material.
Simulation daily use environment, above-mentioned slightly acidic water material is loaded in special filter element, crossing water under the water tap that water speed is 1500mL/min, it is 98min that pH4.5～6.5 change duration, and the volume calculating the slightly acidic water (pH4.5～6.5) that can produce is 147L.
The foregoing is only presently preferred embodiments of the present invention, all equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to the covering scope of the present invention.
