Description

It is a kind of efficiently to remove formaldehyde kieselguhr wall material
Technical field
The invention belongs to the field of building materials, and in particular to a kind of efficiently to remove formaldehyde kieselguhr wall material.
Background technique
It is well known that it is particularly important to the construction of wall after household blank is completed in building household field, thus have Selection to wall material." wall material " refers to related wall plastering construction as its name suggests, the material handled common mortar face. People will not only face the possible pollution in public place now, must be in face of the pollution from private even human body itself.Cause This, in the various canceration symptom growing number of epoch, " green revolution " becomes the necessarily choosing for guaranteeing the ecological balance, Ecological Stabilization It selects.But present finishing material all partially contains organic chemistry glue or adhesive, containing the pollutant being harmful to the human body, sternly Threaten people's health again, because the phenomenon that finishing pollution causes occupant's dizziness and nausea etc. uncomfortable frequently occurs, weight Person seriously threatens the life security of occupant.
With the improvement of living standards, requirement of the people to finishing is also higher and higher.People are pursuing high-grade finishing effect " wall material " certainly will be put forward higher requirements when fruit.Diatom ooze is a kind of using diatomite as the New Wall Material of primary raw material, It is a kind of water-soluble powder shape decorative paint, major function material is passed through certainly by the Diatomeae plant in ocean or lake Right environmental activity deposits the diatomite to be formed, and has fine and smooth, loose, light, porous, water imbibition and permeability by force etc. physical Matter can effectively adsorb the harmful substances such as formaldehyde, benzene, the ammonia to dissociate in air, and can purify in air because of pet, suction The peculiar smell of the generations such as cigarette, rubbish is easy to construct, and is suitable for wall and ceiling is decorated.Therefore, by diatom ooze and traditional inner wall decoration Material combines, and the decorative building material product for having both decorative effect and environment protection health function is made as the new of decorative building material market Dote on, the deep favor by market.
In traditional technology, using nano-titanium dioxide as photochemical catalyst in most diatom ooze wall material, in illumination item Catalytic decomposition is adsorbed on interior harmful substance under part, and most of such diatom ooze wall materials can only achieve absorption harmful substance, decomposes Harmful substance ability is weak, it is difficult to meet urgent need of the people for harmful substances such as persistent high efficiency adsorption-decomposition function formaldehyde.Therefore It need to develop a kind of efficiently except formaldehyde kieselguhr wall material.
Summary of the invention
The technical problems to be solved by the invention: it is only inhaled for the treatment effect of current common kieselguhr wall material PARA FORMALDEHYDE PRILLS(91,95) Attached effect the problem of cannot it effectively being converted, be decomposed, provides a kind of efficiently except formaldehyde kieselguhr wall material.
