Description
Technical field
The invention discloses a kind of wall to spray paint the minimizing technology of advertisement, belong to pollution clean-up technology field.
Background technology
Along with improving constantly of standard of living, the level of consumption of people constantly promotes, and various different industries is constantly risen as emerged rapidly in large numbersBamboo shoots after a spring rain.A lot of businessman is in order to solicit customers or business, can publicize on a large scale shop, great majority are advertising, leaflet publicity, popularization on TV etc., some pedlars then in order to save promotion expense, ignore environmental pollution, advertisement that the wall in each road, community, park sprays paint, these advertisements are generally all made up of paint, coating, therefore, this is also the most headache of current sanitation worker, is also the most unmanageable one " rubbish ".
Wall sprays paint advertisement not only contaminate environment, and affects the attractive in appearance of wall, so must thoroughly eliminate.The paint remover cleaning that the minimizing technology that the normal wall used sprays paint advertisement at present has mechanical removal method, caustic dip method and some markets to sell.
(1) mechanical paint removal method, mainly adopt artificial method to utilize some machine tools to carry out polishing to the used paint layer of wall surface and old glue-line and remove, this needs a large amount of manual labor, and production efficiency is low, easily causes the scuffing of body material;
(2) alkali lye paint removal method, is placed on thing to be removed in alkali lye exactly and carries out immersion paint removal, and soak time at 8 ~ 10 hours, then removes surface residue, complex operation through the artificial hairbrush that uses;
(3) paint remover paint removal method, the enamelled coating of effects on surface breakage can be removed, but paint stripping rate is slow, and removing general paint film needs several tens minutes, the even longer time, is unfavorable for production application.
Except above-mentioned three kinds of methods, also have solvent method and dry ice method, the shortcoming of solvent method is exactly that moiety comprises some harmful materials, can distribute the smell that some stimulate; Although and dry ice thoroughly can be removed wall and to spray paint advertisement and harmless, this technology is owing to being external introduction, and cost compare is high.
Therefore, find a kind of cost low, have no irritating odor, and the high wall of clearance sprays paint, advertisement minimizing technology is necessary.
Summary of the invention
The technical problem that the present invention mainly solves: spray paint in the process of advertisement removal to wall for utilizing traditional method at present, although finally can remove wall advertisement of spraying paint, but ubiquity cost is high, clearance rate is low, complex operation and scavenging process be always with pungency toxic odor, human body is had to the present situation of certain infringement, providing one utilizes solid, liquid two kinds of reagent repeatedly to spray, and economic benefits and social benefits remove the method for advertisement of spraying paint.The method using tetrabutyl titanate, clorox, dehydrated alcohol, Glacial acetic acid, concentrated nitric acid, hydrogen peroxide and hydrochloric acid as raw material, through the obtained liquid reagent A of reaction, again by waste newspaper, deionized water, Textone, Glacial acetic acid, potassium hydroxide, nickel oxide and concentrated nitric acid, thickness reagent B is made through reaction, afterwards A, B reagent is sprayed repeatedly to wall advertisement of spraying paint, and clear water rinses after solar exposure, thus wall advertisement of spraying paint effectively is removed.Not only operation is simple for the method, and cost is low, and elimination effect is remarkable, the reagent used in the process of removing without any irritating smell, life-time service to human body also without endangering.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is:
(1) at normal temperatures, get 10 ~ 15mL mass concentration be 28% tetrabutyl titanate solution and 8 ~ 12mL mass concentration be the chlorine bleach liquor of 32%, with magnetic stirring apparatus strong stirring 5 ~ 8min, mix, fast with dripping of 2 ~ 3mL/min, slowly be added drop-wise to and 50 ~ 60mL dehydrated alcohol be housed and 35 ~ 55mL mass concentration is in the container of the Glacial acetic acid of 98%, control to dropwise in 10 ~ 15min, wait to dropwise, continue stirring 10 ~ 12min, 50 ~ 55 DEG C are warming up to the rate program of 5 ~ 8 DEG C/min in the process stirred, and by 20 ~ 25mL mass concentration be 65% concentrated nitric acid and 30 ~ 35mL mass concentration be 30% hydrogen peroxide pour into successively wherein, after vigorous reaction 18 ~ 23min, instilling 5 ~ 8 mass concentrations is more wherein the hydrochloric acid soln of 3.5%, adjust ph is 2.8 ~ 3.0, leave standstill 30 ~ 35min, be cooled to room temperature voluntarily, obtain mixing solutions, be designated as A reagent,
(2) 85 ~ 100g waste newspaper is got, after putting into 200 ~ 300mL deionized water immersion, 1 ~ 2h, take out, move in hollander and smash, obtain paper pulp and be placed in container, take 10 ~ 15g Textone subsequently, when temperature is 55 ~ 60 DEG C with 30 ~ 35mL mass concentration be 25% Glacial acetic acid mix, to be cooled put room temperature after, with deionized water wash to neutral, pour into and be equipped with in the container of paper pulp, take 5 ~ 8g potassium hydroxide and 2 ~ 3g nickel oxide again, when temperature is 38 ~ 50 DEG C with 20 ~ 30mL mass concentration be 65% concentrated nitric acid vigorous stirring even, to be cooledly put room temperature, instillation 2 ~ 3mL mass concentration is the hydrochloric acid soln of 3.2%, adjust ph is after 2.6 ~ 3.2, pour into equally and be equipped with in the container of paper pulp, treat all to pour into complete, with the rotating speed of 300 ~ 320r/min, stirring 20 ~ 25min is carried out to the container that mixture and paper pulp are housed, obtain viscous mixture, be designated as B reagent,
(3) centered by advertisement of spraying paint, radius is on the wall of 10 ~ 15cm scope, even sprinkling one deck clear water, the B reagent that uniform application above-mentioned steps (2) is obtained in the scope of spraying clear water subsequently, after all having smeared in specialized range, has dried 30 ~ 45min naturally, afterwards on the metope dried, with the A reagent that spray gun obtains with the speed even application above-mentioned steps (1) of 3 ~ 5m3/h, end to be sprayed, be exposed to the sun under the wall after spraying is appointed sunlight 12h;
(4) end of being exposed to the sun is waited, reuse the B reagent that above-mentioned steps (2) is obtained, the wall after shining is smeared, repeatedly smears 1 ~ 3 time, do not stay any space, after 15 ~ 18min, continue the A reagent that specialized range wall spray gun is obtained with the speed even application above-mentioned steps (1) of 3 ~ 5m3/h, treat all to spray end, be exposed to the sun the wall after painting 16h in the sun, and repeatedly rinse with clear water, until A, B reagent all drops voluntarily.
In described step (1) in A reagent each material further desirable 12 ~ 14mL mass concentration be 28% tetrabutyl titanate solution, 10 ~ 11mL mass concentration be 32% chlorine bleach liquor, 55 ~ 58mL dehydrated alcohol, the 45 ~ 50mL mass concentration Glacial acetic acid that is 98%, the 22 ~ 24mL mass concentration concentrated nitric acid that is 65%, 32 ~ 34mL mass concentration be 30% hydrogen peroxide and 6 ~ 7 mass concentrations be the hydrochloric acid soln of 3.5%.
