The invention discloses a cigarette combustion cone fixing method and device. The cigarette combustion cone fixing method has the advantages that an internal structure of a cigarette combustion cone is obtained in situ, the defect of the traditional method that in situ observation can not be carried out on a microstructure inside a cigarette combustion cone part is overcome, the microstructure of the cigarette combustion cone is reserved to the utmost extent, and evidence is provided for intensively studying a cigarette combustion process and a harmful substance production mechanism.

The invention discloses a method for preparing a halogen-free low-temperature fire-retardant fiber, and relates to a method for preparing a self-assembled low-temperature fire-retardant fiber at a room temperature. The invention aims at solving the technical problem that the fire-retardant temperature of the current fire retardant is relatively high. The method comprises the following steps: 1, dissolving titanyl sulfate into water containing sulfuric acid; 2, respectively collocating a copper sulfate solution and a calcium nitrate solution; 3, adding the copper sulfate solution into a titanyl sulfate mixed solution for uniformly stirring, and then adding the calcium nitrate solution for uniformly stirring; 4, standing; 5, filtering; 6, washing; 7 drying. The decomposition temperature of the sulfur-free halogen-free fire-retardant fiber is near 150 DEG C, and the enthalpy value is high. When the sulfur-free halogen-free fire-retardant fiber is used on cotton fabrics, the limiting oxygen index is increased by 30 percent, and the amount of release of smoke is reduced by more than 40 percent. The method belongs to the filed of preparation of fire-retardant fibers.

The invention discloses a bamboo product digestion furnace. The bamboo product digestion furnace comprises a furnace body, wherein a water injection pipe is arranged at one side of the furnace body; avalve is arranged in the middle of the outer surface of the water injection pipe; a boiling pot and a first switch are arranged at one side of the top of the furnace body respectively; a steaming potand a second switch are arranged at the other side of the top of the furnace body. The bamboo product digestion furnace provided by the invention is provided with a steam furnace, wherein the steam furnace adopts a double-layer structure which can be used for reducing the heat dissipation in the steam furnace, so that the utilization rate of resources is improved and the unnecessary wastes can bereduced. No matter whether the boiling pot and the steaming pot work or not, water steam generated by heating is stored above the steam furnace and the steam furnace is in an individual work state. Aheater is used for continuously heating water to generate a great amount of the water steam and high pressure is generated in the steam furnace, so that electric energy not only can be converted intoheat energy but also can be converted into pressure potential energy. Therefore, the energy efficiency ratio is improved and the energy consumption is reduced. The bamboo product digestion furnace uses the electric energy to heat, so that the poisonous and harmful gas can be prevented from generating in a gas combustion process and the pollution on the air environment can be avoided.
