Description
[technical field]
The present invention relates to a kind of compositions and manufacture method and application that can be used for field of purification, particularly relate to a kind of composition and method of making the same and its application on fields such as air cleaning, purification of water quality that purifies antibacterial bacteriostatic release electronegative ion that have.
[background technology]
In recent years,, recognize that more and more we allow of no optimist by residing environment along with the progressively raising of people for the cognition of Environmental Health safety, especially room air pollution and drinking water pollution etc. these aspect daily-life related.
According to statistics, it is quite huge that China is subjected to people's the quantity of indoor pollution infringement every year, and nearly all newly-decorated office, room, the new vehicle of buying (car that especially newly dispatches from the factory, harmful gas concentration is the highest in a year) all have pollution problem.In these polluter, the pollution that has even surpass several times and even tens times of national standard.For example, show that according to the pollution detection result behind some new home finishing its premises formaldehyde exceeds standard 30%～50%, benzene exceeds standard 20%～30%, and (Total Votatile Organic Compound TVOC) exceeds standard 30%～40% to total organic property volatile matter.
And at present, mainly take equipment clean and chemical drugs to purify two kinds of means for indoor air purification both at home and abroad.Wherein, the employed purifier apparatus of equipment clean exists that volume is big, power consumption, problem such as noise is arranged, simultaneously when high pressure sterilization, can discharge ozone, health is caused damage, so equipment clean is not suitable for residential environment and uses, only the specific environment of suitable industry etc. is used.And the mode that chemical drugs purifies then typically uses cleanser.At present, the cleanser that generally uses can be divided into two classes.One class is common aromatic, and itself is effect not, just covers formaldehyde and stink in the air by a kind of fragrance short time.Another kind of then is the chemical drugs that comprises some special material, and it is had an effect by self contained special material and airborne organic compound, reduces in the air content of harmful such as formaldehyde in the unit interval, reaches purification effects.
In addition, the purified product that also has some to adopt the photocatalyst technology, but, influenced its application in some place because this type of product needed is subjected to the restriction of external condition such as ultraviolet light irradiation, make its application facet be restricted.And because photocatalyst factory is limited to more produces on coating, the textile, employing be not environment-friendly water-based binding agent, therefore, also can cause secondary pollution problem.
And aspect the water purification, present more employed additive product with environment-friendly function mostly adopts the nano photo-catalytic or the single tourmaline micropowder of single variety, and these products are not very satisfactory for the water purification effect.For example, the Maifanitum that can be used for adjusting water quality that in some documents, is disclosed, it is to have certain mineralization for the content of mineral substances aspect of improving water, but its shortcoming is that this series products function is single relatively, and the effect time is shorter, is unfavorable for actual use.And at this problem, industry just will have several mineral mixing of different efficacies and make flour, adopt binding agent that this kind flour is made product attached to the ceramic bead surface then and use.And the major defect of this series products is, along with the growth of service time, comes off easily attached to the active substance of ceramic surface, and then causes the reduction of purifying functions.
Therefore, necessaryly develop a kind of novel material, satisfy that indoor air purification and water purify and the demand of deodorization aspect.
[summary of the invention]
To be solved by this invention be existing application in the compositions in air cleaning, water purification technology field purifying air and water quality, the various antibacterials of inhibition, discharge on the effect of aspects such as anion not ideal enough and can not bring into play the technical problem of effect for a long time.
