The invention relates to a molten ferroalloy granulating method. According to the method, a granulating packaging combined device is used for producing ferroalloy fine particles. Column-shaped melt flow of 1600 DEG C to 1630 DEG C vertically falls on a horizontal granulating plate and forms the ferroalloy fine particles through water quenching, the particle size of the ferroalloy fine particles ranges from 2 mm to 50 mm, dewatering is carried out by vibrating a dewatering screen, and the ferroalloy particles are dried through a rotary dryer and conveyed into a packaging machine through a belt conveyer for packaging. The molten ferroalloy granulating method is high in automation degree, short in flow path, small in occupied area, small in ferroalloy particle size and high in uniformity.

The invention discloses a highly-electroconductive biocompatible PEDOT:PSS film modified by malic acid. The highly-electroconductive biocompatible PEDOT:PSS film is prepared through spin coating of mixed liquor of the malic acid and a PEDOT:PSS solution, wherein the mixed liquor contains 1-10 wt% of malic acid. The highly-electroconductive biocompatible PEDOT:PSS film modified by the malic acid has the advantages that the malic acid is used for modifying a PEDOT:PSS film, so that electroconductivity of the PEDOT:PSS film is increased greatly and is 20,000 times more than that of an intrinsic PEDOT:PSS film; the highly-electroconductive biocompatible PEDOT:PSS film keeps biocompatibility and light transparency high, is prepared according to a low-cost, healthy and environment-friendly method, can contact with the human bodies for a long time without irritation and has huge potentials in the fields of medical monitoring and wearable devices; the highly-electroconductive biocompatible PEDOT:PSS film is applied to a piezoresistive transducer as an electroconductive layer and succeeds in enhancing sensitivity of the piezoresistive transducer and reducing detection limit thereof.

The invention discloses a preparation method of titanium powder or titanium alloy powder special for porous titanium film. The method comprises: 1. placing the pressed titanium block or titanium alloy block in a furnace; 2. vacuumizing the furnace and keeping it warm ; 3. Fill hydrogen into the furnace to carry out self-propagating hydrogenation reaction; 4. Titanium block or titanium alloy block absorb hydrogen and saturate to obtain titanium hydride block or titanium hydride block; 5. Crushing and sieving; 6. Coarse powder crushing; 7. Titanium powder or titanium alloy dehydrogenation powder obtained by heat preservation and dehydrogenation; 8. Titanium powder and titanium alloy powder obtained by crushing, sieving, magnetic separation and flotation. The present invention utilizes the heat released by the hydrogenation reaction to meet the heat energy supply required for the continuation of the hydrogenation reaction to carry out a self-propagating hydrogenation reaction, reducing the increase in heat generated by the reaction, avoiding incomplete hydrogenation of the titanium block or titanium alloy block, and improving the efficiency of the titanium block or titanium alloy block. The degree of hydrogenation embrittlement of titanium alloy block can finally obtain finer and uniform titanium powder or titanium alloy powder, which improves the quality of titanium powder or titanium alloy powder.

The invention discloses a method for processing crispy gourd seeds, which belongs to the field of food production technology. It includes the steps of boiling and stewing, draining, frying and peeling, cooling, winnowing and removing impurities, and oiling. The present invention improves the existing gourd seed processing technology, thereby solving the problems that the existing cooked gourd seed products are not easy to chew and the appearance is not good due to dirty spots on the surface of the shell. The cooked gourd seed products produced by the process of the present invention have good appearance Higher and uniform, the shell has toughness and is not fragile, easy to separate the shell and kernel, and has the advantages of high cracking rate, and the quality standard requirements for gourd seed raw materials are low, which reduces the purchase cost.

The invention discloses a peeling antifouling paint of a single-component propeller and relates to the field of the coating technology.The paint is prepared by the following raw materials, in quality percentage,15-65% of resin binder, 0-12% of thinner, 25-65% of copper antifouling agent,5-15% of zinc oxide, 0-10% of organic antifouling agent and 0.5-2% of thixotropicagent; and the resin binder is any one or more of barium petroleum sulfonate, butter,lanum, methylsilicone oil and hydroxyl silicone oil. The antifouling paint provided in the invention is obtained by mixing the above materials uniformly through a high-speed dispersing process. The antifouling paint can achieve temporary antifouling action on the propeller when the ship stops to avoid fouling bioattachment; if the bioattachment is available, marine organism can peel and fall along the coating under the effect of the centrifugal force and current scouring of the propeller when the ship sails; the propeller surface must keep clean without bioattachment;and the antifouling perid is above six months.
