Description
Technical field
The present invention relates to bamboo charcoal ceramic processing technique field, more specifically a kind of anti-bacterial bamboo charcoal ceramics meal
The preparation process of tool.
Background technology
Bamboo charcoal is a kind of outstanding sorbing material, it has the features such as hole is more, large specific surface area, adsorption capacity is strong, and
And the growth cycle of bamboo charcoal raw material bamboo is short, abundance, it can be not only used for fuel, air purification deodorization, environmentally friendly water purification,
Soil improvement, environment damping etc., and available for radioresistance and electromagnetic shielding material, flame retardant composite material, preserving fruit and vegetable utilizing
The high-technology fields such as material, health care material and industrial semi-conducting material, therefore deep processing and utilization is carried out to bamboo charcoal,
Resource pressure problem can not only be alleviated, but also can sustainable development path be walked with environmental protection.
Bamboo charcoal crockery is a kind of high with porosity, and absorption property is strong, and bulk density is low, and percent of firing shrinkage is low, by force
Degree is high, discharges anion and the composite ceramics tableware of radiation infrared function, is excellent composite table-ware porcelain.
In recent years, by the self assembly and load synthetic technology that nanoparticle is carried out based on the surfaces externally and internally of porous material
The research hotspot of field of nanometer material technology is become, silver type antibacterial agent is in safety, persistence, antibiotic property, heat resistance etc. tool
There is the performance more more excellent than organic antibacterial agent.There is assembling of numerous scholars to nanometer silver type antibacterial agent in different materials in foreign countries
Preparation conducts in-depth research, and the particularly research of Japan in this respect achieves bigger progress, and part achievement
Have been realized in industrialization.
The sterilization mechanism of nano silver antimicrobials：When silver ion in the haptoreaction of silver ion, i.e. antibacterial product with it is thin
After bacterium haptoreaction, microorganism proper constituent is caused to destroy or generate dysfunction.When micro silver ion arrival microorganism is thin
During after birth, because the latter is negatively charged, by Coulomb attraction, making two all securely absorption, silver ion penetration cell wall enters into the cell,
And and its（-SH）Group reacts, and makes protein coagulation, destroys the activity of cell synzyme, cell loss division growth ability and it is dead
It dies.Second is that light-catalyzed reaction, the trace silver of material surface distribution, under the action of light, can play the role of catalytic active center,
The oxygen in water and air is activated, generates hydroxyl radical free radical（OH-）And active oxygen ion（O-2）, active oxygen ion has very strong
Oxidability can destroy the proliferative capacity of bacterium in a short time and make cell death, so as to achieve the purpose that antibacterial.
So utilizing the sterilization mechanism of nano silver antimicrobials on tableware, nano silver antimicrobials are applied on tableware, are made
Tableware has durable antibiotic, and the technical matters can be able in large-scale production extensively using as this tableware production row
Important a research direction and research topic in industry, so meaning is especially important.
In the prior art, as Chinese patent Authorization Notice No. is：A kind of coating catalysis material disclosed in CN104478462 B
Crystallite bamboo charcoal Tao Zhu and preparation method thereof, disclosed in the program and coat catalysis material on bamboo charcoal ceramic pearl, make the bamboo charcoal ceramic
Pearl has the catalytic effect of the catalysis material, and catalysis material includes nano silver coating, the bamboo charcoal ceramic pearl is made to be combined with catalysis material
Form composite catalyzing body.But only simply the suspension that bamboo charcoal ceramic pearl is put into catalysis material is glued in the program
It applies, its surface is made to adhere to catalytic materials material layer, simple for process coarse, catalysis material Nano silver solution usage amount is huge, and
It makes pottery cati material its uniformity, the flatness of bead surface, can not all stablize guarantee；On the other hand, the bamboo charcoal ceramic pearl of the program
Only catalytic materials material layer is simply adhered on surface, all can be seriously once pottery bead surface is damaged or surface adhesive layer is worn
The effect of influencing the catalysis material.
Therefore, this field manufacturing enterprise, urgently need it is a kind of can not only make nano silver catalysis material usage amount low, drop
Low production cost is low, and can ensure that the ceramic has effects that the production technology of lasting nano silver catalysis material, makes
The compound porcelain is more advantageous to the production, popularization and application of enterprise.
