Abstract: Technical fields of building external wall decoration and material manufacturing, providing a mildewproof and antirot high-strength cement particle board and a preparation method thereof. The preparation method includes: (1) sequentially carbonizing and water-washing a shaving, and mixing the obtained carbonized shaving with a cement gelling agent, a curing agent aqueous solution and water to obtain a mixture; (2) molding the mixture to obtain a pre-molded material; and (3) sequentially curing and drying the pre-molded material to obtain the mildewproof and antirot high-strength cement particle board. Compared to ordinary cement particle board, which is not subjected to carbonization treatment and water-washing, the cement particle board of the present invention can effectively avoid mildew and rot, and can significantly improve the mechanical strength and durability thereof, helping to extend the service life of the cement particle board.

Abstract: A method for disinfecting explants of Kadsura coccinea stems with buds and a method for directly inducing rapid proliferation of sterile buds by using the explants of Kadsura coccinea stems with buds involve processes such as selection, treatment and disinfection of explants, primary culture, subculture proliferation culture. The problem of difficulty in tissue culture and primary culture of Kadsura coccinea stems is solved, and the advantages include low contamination rate of explants, high propagation rate and robust proliferation of axillary buds. This allows obtaining sterile axillary buds of Kadsura coccinea through tissue culture, and provides support for tissue culture, rapid propagation and factory seedling of Kadsura coccinea in the future.

Abstract: A solenoid valve includes a main valve, a first auxiliary valve, a second auxiliary valve, a main valve body, and an auxiliary valve body. The main and auxiliary valve bodies are axially parallel and detachably connected. The main valve is mounted on the main valve body, the first and second auxiliary valves are mounted on the auxiliary valve body, which is provided with an air inlet, a cylinder port and an air discharging port. The air inlet communicates with the main valve through a first air passage. The cylinder port is sequentially in communication with the first and second auxiliary valves and the main valve through a second air passage. The air discharging port sequentially communicates with the first and second auxiliary valves and the main valve through a third air passage. The main and second auxiliary valves are solenoid valves. The first auxiliary valve is a hand-operated valve.

Abstract: The present invention discloses a method for quick hot-press forming of laminated wood. The method includes: drying a machined small wood material to a moisture content of 5-8 wt %; gluing the dried small wood material, and assembling and laying the dried small wood material to be a square material or a sheet material, where an adhesive for the gluing is a water-soluble adhesive having a solid content of 45-60 wt %; clamping the square material or the sheet material through a three-dimensional metal clamp; sending the clamped square material or sheet material together with the clamp into a microwave heating machine for microwave heating to obtain a formed laminated wood, where the time from the gluing to the entry into the microwave heating machine is controlled to not exceed 15 min.

Abstract: A high-strength network structured nano-carrier material and a preparation method and application thereof. A nano-cellulose solution and graphene are mixed and ultrasonication is performed in an ultrasonic pulverizer to obtain a nano-cellulose/graphene suspension. The suspension with a phenolic resin adhesive is mixed and stirred to obtain a nano-cellulose/graphene/phenolic resin suspension. The nano-cellulose/graphene/phenolic resin suspension is injected into a mold. The mold is placed in a freeze dryer for freezing and vacuum dried in two stages to obtain a nano-cellulose/graphene/phenolic resin aerogel. The aerogel is preheated and cured in a muffle furnace, then subjected to a high-temperature thermal decomposition treatment in a tube furnace to obtain a nano-carrier material having a high-strength network structure. The preparation method is simple and convenient, low in cost, environmentally friendly and green.
