The invention discloses a pretreatment liquid for direct injection of polyester fiber through dispersive ink and a direct injection digital printing process. The pretreatment liquid comprises, by mass, 0.2-5 parts of thickener, 1-10 parts of dispersion promoter, 2-5 parts of sodium chloride and 76-95 parts of water. The pretreatment liquid is semi-thick liquid, polyester fabric after going through impregnation or padding treatment liquid is dried, injection printing of dispersive dye ink is performed, high-temperature steaming baking is performed for color fixing after drying, water washing is performed, and then drying is performed to obtain a printing finished product. The pretreatment liquid is simple to prepare, convenient to use and suitable for direct injection process digital printing of all fabric high in polyester content, and the pretreatment liquid is easy to wash away after printing, so that hand feel of fabric is unaffected. Conventional heat transfer printing is replaced by the dispersive direct injection process, and transfer printing paper is not used, so that the direct injection digital printing process is environment-friendly. The pretreatment liquid can effectively prevent ink from spreading around on the polyester fabric, so that patters are ensured to be exquisite and lines are ensured to be clear after printing; color yield rate is high, printing is saturated and bright in color, and visual three-dimensional sense is high.

The invention discloses a preparation method of an environment-friendly semi-organic insulating coating for high silicon steel, belonging to the technical field of preparation of silicon steel insulating coatings. The method comprises the steps of pre-treating the surface of high silicon steel before coating, and then preparing an environment-friendly semi-organic insulating coating solution for high silicon steel, wherein the coating solution comprises the following components in percentage by mass based on the total mass: 10-15% of styrene-acrylic emulsion, 20-30% of aluminum dihydrogen phosphate solution, 2-3% of glycerin and the balance of deionized water; and finally coating the pre-treated surface of the high silicon steel with the insulating coating solution while controlling the coating quantity to be 0.8-1.2g / m<2>, and curing and sintering at 200-300 DEG C for 0.5-1 minute to obtain the insulating coating. The semi-organic insulating coating is suitable for the high silicon steel (iron-silicon alloy containing 4.5-6.7% of Si), does not contain heavy metal elements such as chromium, is safe and environment-friendly, has good adhesiveness, insulating property, corrosion resistance, heat resistance and punching performance, and can meet relevant performance requirement of the high silicon steel.

The invention discloses a healthcare food with effects of reducing weight and facilitating feces excretion and a preparation method thereof. The healthcare food comprises 2-20 parts of folium sennaee extractive, 20-80 parts of L-carnitine tartrate and 10-60 parts of natural plant extractive. The preparation method comprises the following steps: dissolving ethylcellulose in 75% ethanol so as to prepare a coating solution of L-carnitine tartrate; carrying out embedding treatment on L-carnitine tartrate powder by using the coating solution so as to prepare loose and uniform micro-capsule particles for later use; respectively grinding the folium sennaee extractive and the natural plant extractive, and sieving with a 80-mesh screen; then mixing the formula amount of three materials for 20-40 minutes so as to obtain mixed powder. According to the formula of the healthcare food, L-carnitine tartrate and the natural plant extractive are used as the raw materials and are processed into a compound preparation, so that the adverse reactions and accompanying side effects of western medicines can be avoided, and the problems that the traditional Chinese medicine does not take obvious effect and is short in effect can also be solved.

Provided is a flux which is capable of improving dissolubility of a resin coating and inhibiting any corrosion. The flux is a liquid flux which is obtained by dissolving an amine compound, an activator and an acid into a solvent and contains 10 through 20 mass% of alkanolamine as the amine compound, 5 through 10 mass% of amine fluoride salt as the activator, 10 through 20 mass% of an organic acid which neutralizes the alkanolamine to form a water-insoluble salt as acid, and 50 through 75 mass% of the solvent.
