Pigment color paste for on-line color mixing, surface sizing and coating of culture paper pulp and preparation method thereof

The invention discloses a pigment color paste for the on-line color mixing, surface sizing and coating of culture paper pulp and a preparation method thereof. At present, most pigment color pastes cannot meet the requirements of paper-making factories, have poor stability and cannot easily control obvious defects such as poor diluting stability, low retention rate and poor color light consistency on the application aspect. The pigment color paste consists of a high-performance organic pigment, a dispersing agent, a wetting agent, a retention assistant agent, a function additive and deionized water; and the pigment color paste is prepared according to a plurality of steps such as mixing, wetting, dispersing and grinding all the components. The prepared nano-colored paste with high color content, low viscosity and high retention is stable to store; the paste has hard water resistance and high dilution stability, can be on-line directly added; the paste has a bright color, high retention rate and a small use amount; the paste has good light resistance and thermal resistance and can greatly improve the product quality; and the paste has good compatibility and cannot cause bad physical and chemical reaction with other paper-making chemicals when being added in a correct position.

White-smoke-free promotion flux for steel fastener hot dip galvanizing and application process of white-smoke-free promotion flux

The invention relates to the technical field of steel fastener hot dip galvanizing, in particular to white-smoke-free promotion flux for steel fastener hot dip galvanizing and an application process of the white-smoke-free promotion flux. The white-smoke-free promotion flux for steel fastener hot dip galvanizing comprises the following components: 100-200g / L of zinc chloride, 10-40g / L of magnesiumchloride, 8.0-13g / L of nickel chloride, 6.0-12g / L of hydrochloric acid, 2.0-3.5g / L of hexamethylenetetramine, 2.0-10g / L of a flux additive, and the balance of water. The application process of the white-smoke-free promotion flux comprises steps of degreasing, water cleaning, rust-removing, secondary water cleaning, promotion flux adhering, drying, galvanizing and the like. The white-smoke-free promotion flux for steel fastener hot dip galvanizing disclosed by the invention does not contain ammonium chloride which generates white smoke while encountering molten metal zinc, and can greatly reduce generation of soot during hot-dip galvanizing of the steel fastener; and a hot-dip galvanizing process which uses the promotion flux is more optimized, and has the advantages of being low in production cost, stable in plating assistance quality, capable of producing steel fasteners for hot dip galvanizing on a large scale, and the like.

Green antibacterial detergent with NP10 antimicrobial peptide and preparation method and application of green antibacterial detergent

The invention provides a green antibacterial detergent with NP10 antimicrobial peptide and a preparation method and application of the green antibacterial detergent and belongs to the technical field of detergents. The green antibacterial detergent is prepared from, by mass, 14-20% of an anionic surfactant, 4-12% of a nonionic surfactant, 0.10-0.15% of the NP10 antimicrobial peptide, 0.08-0.12% of sodium citrate, 1-3% of urea, 0.08-0.12% of EDTA disodium, 0.1-0.3% of sorbitol, 0.1-0.3% of vitamin E and the balance water. According to the NP10 antimicrobial peptide, in cooperation with the sodium citrate, the bacterium inhibition performance is improved, in cooperation with the anionic surfactant and the nonionic surfactant, the decontamination capacity can be improved, and the green antibacterial detergent also has the performance of resisting hard water. The green antibacterial detergent has the excellent decontamination capacity and can also moisten and protect the skin, the antimicrobial peptide has an excellent antimicrobial function, the application quantity of the green antibacterial detergent is lower than that of a chemical antibacterial agent, and the green antibacterial detergent is healthier than the chemical antibacterial agent.
