Aquifer amendment containing multiple active microorganisms and method of preparing the same

The invention relates to a water improver with multiple active microbes and a preparation method thereof, which adopts two or a plurality of following microbial strains, comprising a bacillus licheniformis, a bacillus subtilis, a bacillus megaterium, a lactobacillus plantarum, a saccharomyces cerevisiae, a candida lipolytica, bacillus pumilus, bacillus cereus, a rhodopsedomnas palustris, an alcaligenes faecalis and an arthrobacter globiformis. After the femination of the microbial strains, the preparation of the liquid is that the single microzyme zymocyte liquid is mixed and stirred in proportion; or the mixed bacteria solution is concentrated; or the concentrated single microzyme zymocyte liquid is mixed and stirred according to the proportion of the single microzyme zymocyte liquid, and is prepared into a mix bacteria solution. The mix bacteria solution is mixed homogeniously with an added assistant agent. The total amount of the live bacteria within the warrenty period is 106 to 1010 per milliliter. The preparation of the solid inoculant is that the zymocyte liquid is dried after the absoption of the adsorbent on the zymocyte liquid, is prepared into a solid bacterial powder and mixed evenly with the added assistant agent. The total amount of the live bacteria within the warreny period ranges between 106 and 1011 per gram. The invention has multi-function and stable effect and is suitable for treating various water bodies.

Electromagnetic current coupling field assisted hybrid melting-brazing method for laser-TIG arc and equipment

The invention discloses an electromagnetic current coupling field assisted hybrid melting-brazing method for a laser-TIG arc and equipment. In addition to the use of the welding zone, an alternating magnetic field is added to control properties of plasma formed through ionization of laser, arc and a raw material metal, thereby improving the laser utilization rate. Under the electric field assisted comprehensive effect, the weld melting depth is increased, and the assistant effect on the melting bath of the liquid-state brazing filler metal for laser-arc melting-brazing is realized through electromagnetic stirring and excitation and enhancement, thereby promoting the orderly flow of the liquid-state brazing filler metal and the rupture, wetting, spreading and proliferation of the liquid-state brazing filler metal on the surface of the high metal material, improving the full mixing of the liquid-state brazing filler metal and the base metal formed by melting the low-melting-point metal material, improving the uniformity of the components of the brazed weld, stabilizing the welding process, reducing welding defects, increasing the welding speed, improving the weld formation, optimizing the structure and performance of the brazed weld, and improving the quality of the brazed joint. Moreover, the equipment has the advantages of simple structure, flexible application, low cost, good effect and easy realization.

Preparation method of multilayer sandwich type electrostatic-spinning polymer nanofiber composite membrane

The invention discloses a preparation method of a multilayer sandwich type electrostatic-spinning polymer nanofiber composite membrane. The preparation method comprises the steps of firstly, spinning a polymer spinning liquid into a fiber membrane in an electrostatic manner, then spraying a spraying liquid containing inorganic nano-particles to the surface of the electrostatic-spinning fiber membrane by virtue of a jetting technique, continuously spinning the fiber membrane, and repeatedly carrying out the steps according to specific conditions so as to prepare the multilayer sandwich type composite membrane. As the inorganic nano-particles are adhered to the surface of the fiber membrane, not only can the ultrahigh specific area and the specific structural advantage of a nanofiber be brought into full play, but also the selectable ranges of the spraying liquid and the polymer spinning liquid are flexible, so that spraying liquids containing different inorganic nano-particles can be sprayed to electrostatic-spinning fiber membranes made from different raw materials according to actual demands so as to prepare sandwich type composite membranes with different functions, stable structures and good properties, and the application range of the electrostatic-spinning polymer nanofiber composite membranes is expanded.

Moisture-absorbing and bacteriostatic base cloth of beauty mask made of spunlace non-woven fabric and preparation method thereof

ActiveCN108166157AImprove the problem of viscosity instabilityGood viscosity stabilityNon-woven fabricsArtifical filament manufactureYarnViscose
The invention discloses moisture-absorbing and bacteriostatic base cloth of a beauty mask made of spunlace non-woven fabric and a preparation method thereof, relating to the technical field of non-woven fabrics. The moisture-absorbing and bacteriostatic base cloth is composed of following fibers, by weight, 40-60% of sodium alginate viscose fibers and 40%-60% of chitosan viscose fibers. The preparation method comprises the following steps: firstly preparing the sodium alginate viscose fibers and the chitosan viscose fibers; next, respectively opening and carding the chitosan viscose fibers; then, netting in an intersected manner; reinforcing a fiber net that is laid well by spunlace, drying the fiber net so as to obtain the base cloth. Sodium alginate and chitosan are respectively added into viscose primary liquid to spin viscose yarns. Epichlorohydrin is utilized such that sodium alginate and chitosan are closely combined with viscose. Sodium alginate viscose fibers and chitosan viscose fibers produced show great air permeability, water retention and moisture absorption capabilities and are capable of eliminating bacteria and inhibiting bacteria. Then, non-woven fabric made by intersecting netting and spunlace reinforcement can be used for material of base piece of the mask. The moisture-absorbing and bacteriostatic base cloth is comfortable and skin-friendly and capable of diminishing inflammation and inhibiting bacteria. Skin can be cleaned and effectively protected. The damage of cosmetics to the skin is minimized.

Universal air-cushioning material

InactiveUS20070131575A1Broad mutual contact areaStable cushioning functionBagsSacksCushioningWadding
The invention intends to cheaply provide a cushioning material that can pack articles to be packed different in shapes and dimensions with a simple structure and stably and that can withstand transportations for long periods under severe conditions. A universal air cushioning material is formed in such a manner that side portions forming end portions of above and below and left and right external frames of two superposed rectangular synthetic resin films made of a same raw material are thermally fused and, between the side portions, an intermediate portion thereof is arbitrarily thermally fused in accordance with a dimension and shape of the article to be packed to dispose a plurality of partitioned peripheral portions; at arbitrary positions in the vicinity of the side portions of the peripheral portions, at least a pair of notches is disposed horizontally symmetrically in accordance with a dimension and shape of the article to be packed and, in the peripheral portions, at least one air passage port is disposed to form a plurality of mutually communicated air chambers to enable to arbitrarily vary a contact area between the air chambers and the article to be packed or an inner wall of the transporting vessel; to at least one of the air chambers an air inlet port is disposed to inject air from the air inlet port to expand an entirety of the air chambers; and thereby an inside thereof is pressed against the article to be packed and an outside thereof is pressed against an inner wall of the transporting vessel.
