Description
Technical field
The present invention relates to a kind of preparation method and application of chitin thimerosal.
Background technology
Mention disinfectant, people at first expect may be pasteurization liquid, bleaching powder with pungent taste.These traditional disinfectants are most can to cause secondary pollution to environment; Along with bacterium and virus drug resistance improve constantly, new virus constantly occurs, and its effectiveness reduces; In addition, its toxicity or corrosivity also can damage when being directly used in skin.
Chemosterilant has been experienced in the development of sterilization product (technology), as the application of clorox, the tincture of iodine, peroxide, the application of hibitane, improved chemosterilant, as make compound for the bromogeramine that improves bactericidal effect, for improving glutaraldehyde+hardening agent, the preservative of sterilization speed, and the change of formulation etc.
The expert points out that the bactericide and the disinfectants that are regardless of occasion, a large amount of use in time ground chemical analysis will cause serious consequence to environment.Using the most direct purpose of disinfectant is the kill harmful microorganism, allows virus have no place to hide.But these disinfectants kill is not limited to harmful microorganism, and useful microorganism is also together killed.In addition, long-term a large amount of chemical analysis disinfectant, bactericidal agents of using have made the microorganisms pesticide resistance, and sterilization effect reduces greatly; And the medicament residue that remains in the environment such as our life, production is more and more, becomes new pollution source, grows new harmful microorganism, we healthy of serious threat.Such as the peroxide disinfectant, because they have strong oxidability, can be with all microorganism killings.And the peroxide disinfectant of high concentration also stimulates, damages mucocutaneous, corrosives.The high concentration chlorine-containing disinfectant has the obvious stimulation effect to people's respiratory mucosa and skin, and article are had corrosion and discoloration, still is carcinogen simultaneously.Because the disinfectant of chemical analysis can not natural degradation, also can cause secondary pollution to environment.
Paying attention to 21st century natural, healthy, environmental protection, biotechnology has just like become the topic of very hot door.In past 50 years, people use chemical antibacterial agent to do disinfection, and the problems such as toxicity, pesticide resistance, safety and the feature of environmental protection that face can't effectively solve always, thereby influence its range of application, and then limit its development.Biological product itself is nontoxic, and organic matter is changed into after simple, harmless inorganic matter such as carbonic acid gas, the water, and these microorganisms are reduced to extinction thereupon, do not have residue or secondary pollution.
" sterilization method " of biodegradation technique is, extract, tame the beneficial microbe of occurring in nature, to surpass the speed decomposing organic pollutant of hundreds and thousands of times of other natural bacterias, make harmful virus and bacterium not have host, parasitic media or source of nutrition, until its death.European at present and the U.S. is generally using biological degradation and disposal of refuse technology, i.e. bio-enzyme degradation technology.
Because a kind of enzyme is only effective to a bacterioid, broad-spectrum antiseptic, just must act on simultaneously by several enzymes.But in enzyme composite, various enzymes are the use activity of can cancelling each other together, and very easily loses activity, and is difficult for preserving.
In recent years, chitin (Chitin) is because possess excellent physiological function, and safety non-toxic, and its pharmaceutical value is generally acknowledged by clinical medicine.Its biologically active comprises and suppresses growth of microorganism, physiological adaptation, Biodegradable, anti-inflammatory, stops blooding, preserves moisture, promotes regeneration, adsorbs heavy metal and eliminates toxin etc.Chitin (Chitin) and multiple derivative (Chitosan) thereof all have effect such as antibiotic, anti-infective, antiviral, antitumor in various degree.A large amount of free amine group positive charges that distributing on the chitin molecule chain form cationic polyelectrolyte in water, effects such as the link of bridge formation, electric field neutralization, ionic adsorption, coordination chelating, radical reaction are arranged.Physio-chemical study shows that chitin can be removed suspension in the water, organic matter, peculiar smell, pigment in water treatment, and can remove heavy metal harmful in the water and bacterium.Yet natural chitin itself is insoluble in water, extremely be difficult for being utilized, so its range of application and effect is limited.Chitin has another name called shitosan, chitosamine, chitin, chitosan, chitin, chitosan, removing protein for natural shrimp and crab shells gets with calcareous purifying afterwards, structure and fiber-like seemingly belong to animal fiber, avirulence, have no side effect and have positively charged distinct advantages.
And the chitin product can be divided into for four generations according to the improvement and the quality of technology: crab shrimp shell meal, polymeric acidic dissolubility chitin, low macromolecule water-solubility chitin, macromolecular water-soluble chitin.
The macromolecular water-soluble chitin, quality far surpasses all existing chitin products, have the advantage that " polymer acid dissolubility spherical chitosan " reaches " low macromolecule water-solubility spherical chitosan " concurrently, but the shortcoming of having got rid of both, be global scientist's dream high-grade chitin for a long time, really can bring into play the superfine product of all good characteristics of natural chitin.The macromolecular water-soluble chitin has powerful biologically active, the adsorptivity to harmful substance, safety, stability and natural environmental-protective concurrently, and its natural resources that will pass into silence of making reclaim utilization once again, and can not bring secondary pollution.
Although people have had certain cognition to the antibacterial mechanisms of chitin,, the antibacterial efficacy that how to improve it makes it to reach the purpose of sterilization, is the problem of scientists study always.Therefore, in the sterile products worldwide, chitin is also as just a kind of auxiliary adding ingredient.At present, still not having the document record is the natural disinfectant bactericidal agent product of active ingredient with the chitin.
The present invention is directed to the shortcoming and the plurality of advantages of utilizing chitin of chemosterilant, carried out meticulous research, finished chitin thimerosal of the present invention.
