The hand sanitizer is a cleaning product designed for removing stains and bacteria on hands, and consists of necessary active ingredients, sterilization ingredients and auxiliary ingredients.
And (2) a surfactant: the basic function is cleaning function, the hand cleaner mainly cleans greasy dirt on hands, the surfactant can generate abundant foam, the surfactant is dissolved in water at a lower concentration, the surface tension of a solution system can be greatly reduced, a large number of micelles can be formed in the solution along with the fact that the surfactant reaches the critical micelle concentration, and the micelles can play roles in wetting, solubilizing, emulsifying and dispersing to clean the greasy dirt.
Humectant: for market demands, not only simple cleaning and decontamination, but also human body feeling after cleaning is very important, and dryness and roughness of hands are avoided, so that a humectant is required to improve body feeling, and the humectant is defined as a substance capable of keeping moisture in the stratum corneum of skin or delaying and preventing volatilization of moisture in the stratum corneum, and particularly can show the characteristic under low humidity.
And (3) a thickening agent: when the hand sanitizer is used, if the viscosity is too small, the hand sanitizer is very easy to slide away from hands, waste is caused, the detergency is also affected, and the viscosity is adjusted to be too large, so that the hand sanitizer is not easy to squeeze and rinse. The hand sanitizer has proper viscosity, can enhance the sensory effect of consumers, and adopts sodium chloride and polyacrylic acid PPA as thickening agents.
Complexing agent: the usual water quality contains Ca 2+ 、Mg 2+ Some surfactants are relatively poor in hard water resistance and precipitate with metal ions in such water to affect the performance of the detergent. The complexing agent is added into the detergent, can be complexed with the metal ions to be eliminated in the form of a dissolved complex, so that hard water is softened, EDTA-2Na is adopted as the complexing agent, the complexing agent can form a soluble annular structure in water, and the metal ions are bound in the annular structure, so that the metal ions are prevented from forming precipitates, and the solution has a good appearance.
Essence and pearl powder are used for improving the touch effect of the hand washing liquid, and the taste and the appearance required by customers can be selected according to the needs.
A bactericide: because hypochlorous acid is uncharged and has relatively low molecular weight, the hypochlorous acid can penetrate cell walls more than other bactericides or bacteriostats, and has higher oxidation reaction speed with organic matters (namely key components of microbial cells), so that the sterilizing effect is more efficient, and the aim of killing bacterial propagules, viruses, fungi, tubercle bacillus and bacterial spores can be fulfilled by penetrating cell membranes in a mode of attacking physiologically relevant molecules (ammonia, thioether, mercaptan, nucleotide and the like) only under the condition of low concentration so as to oxidize proteins.
Regarding the electrolysis process and anode used in the present invention:
first,: the method comprises the steps of pre-treating the surface of a titanium substrate, wherein the surface treatment comprises degreasing and sand blasting, the degreasing step is an unnecessary treatment process, mainly because micro-arc oxidation is carried out later, the micro-arc oxidation process has larger voltage, and an obvious anodic electrochemical degreasing process can occur, so that degreasing is unnecessary, but the degreasing can influence the bonding force between a micro-arc oxidation layer and the substrate to a certain extent, therefore, the method is used for pre-degreasing the substrate, and the substrate is subjected to sand blasting after degreasing, wherein the main purpose of sand blasting is not to remove oxidation, the main purpose of sand blasting is to improve the surface roughness of the substrate, and the impurity on the surface is removed, so that the bonding area of the substrate and a micro-arc oxidation intermediate layer can be obviously improved by sand blasting, and the bonding force between the substrate and an active layer is further improved.
Secondly, regarding the middle layer, the middle layer has the functions of increasing the binding force between the titanium matrix and the active coating, resisting gas scouring, preventing the coating from peeling off prematurely, simultaneously, the existence of the middle layer also blocks the diffusion and permeation of oxygen to the matrix, slows down the formation speed of the non-conductive titanium oxide film between the matrix and the active layer, delays the passivation and deactivation of the matrix, and improves the service life of the oxide anode
And (5) a life. The intermediate layer in the prior art is mainly an intermediate layer such as SnO2, sn-Sb oxide, ir-Co oxide, sn-Sb-Mn oxide, sn-Ru-Mn oxide, ru-Sn-Sb oxide, ru-Sb-Mn oxide, nb-Sn oxide and the like, and of course, part of the intermediate layer is a titanium-based anode oxide film, the intermediate layer is a titanium-based micro-arc oxide film, the bonding force between a substrate and an intermediate layer can be effectively improved by taking the anode oxide film or the micro-arc oxide film as the intermediate layer, mainly because the oxide film is generated in situ, no obvious interface exists between the intermediate layer on the surface of the titanium substrate and the substrate, the transition is good, and the coating, electroplating or other deposition methods have obvious interfaces, when the interface is used for subsequent heat treatment of an active layer, certain heat stripping or heat stress accumulation can be necessarily generated, in addition, compared with an anodic oxide film, the micro-arc oxide film is far higher than the micro-arc oxide film in corrosion resistance (salt spray resistance), hardness and service life, but the micro-arc oxide film has lower porosity in morphology, so that the binding force between an active coating and a substrate is reduced, the surface of the pure titanium oxide micro-arc oxide film is rough, discharge residual holes with different sizes exist, the range of the holes is large, the porosity is about 2-8wt.%, the main contribution of the porosity is a surface porous layer, the physical and chemical contribution is a transition layer, the binding force is a dense layer at the bottom, the pore absorption rate of the dense layer is lower than 1%, and the specific surface area of the micro-arc oxide sliding film is 10.32m 2 And/g. In contrast, the W element is added in the micro-arc oxidation film, so that the micro-arc oxidation film has higher porosity and the specific surface area is increased to 13.9 m 2 The improvement of the porosity and the surface area obviously improves the contact area of the intermediate layer and the active layer, improves the binding force of the intermediate layer and the active layer, and also provides the active layer in the composite synergistic activation processMore active sites, tiO in the intermediate layer obtained 2 About 50-55wt.%, and about 25-30wt.% W, the Ti component being more due to Ti 4+ Takes part in at least two main reactions, and W takes part in at least one main reaction, the reaction formula is as follows:
Ti 4+ +2OH - +2H 2 O→TiO 2 +2H2O +
Ti 4+ +2WO 4 2- +TiO 2 +2WO 3 。
