The invention provides a preparation method of solid perfume. The preparation method comprises the following steps: adding 85-95% of polyethylene glycol 6000 and 0.5-1.5% of sodium citrate into a jacketed pan, then adding purified water which is equal to the sodium citrate in weight, heating to 75-85 DEG C; adding 2-7% of a mixture of borneol and a fragrant source ingredient after carrying out thermal mixing for 30 minutes; rapidly uniformly stirring, then dripping the mixed liquid into paraffin oil being 0-7 DEG C while the mixed liquid is hot, so as to prepare a ball which is 1-3mm in diameter; centrifugally removing the paraffin oil; and packaging the ball into a proper container, so as to obtain the solid perfume, wherein the mixture of the borneol and the fragrant source ingredient selects polyethylene glycol 400 as a dispersing agent; the mass ratio of the polyethylene glycol 400 to the borneol to the fragrant source ingredient is 6 to 1 to 2. The preparation technology is simple and mature; the obtained solid perfume is lasting in sweet smell; the sweet smell can be kept for over six weeks in a high temperature condition in summer, and kept for over eight weeks in spring, autumn and winter.

The invention provides a method for preparing a very rich microporous carbon material based on carboxylation anchoring, which comprises the following steps: (1) pretreating waste biomass, washing, drying and pulverizing. (2) Immerse the biomass particles in the small molecular organic carboxylic acid solution, and then dry them in a blast drying oven. The dried materials are reacted at 100-200°C for 1-12 hours, and then the materials are washed to neutral , and the carboxylated material was obtained after drying. (3) At a temperature of 50-150°C, immerse the carboxylated material in a 0.1-2mol / L alkali metal hydroxide solution for ion exchange for 1-24 hours, and make the metal ions evenly distributed through the anchoring effect of the carboxyl group On the material surface, then wash with water to remove excess alkali to neutral and dry. (4) Finally, the obtained material is placed in a tube furnace under N 2 Carry out high-temperature carbonization under the atmosphere, and obtain the final product rich microporous carbon material after washing and drying.

The invention discloses a preparation method of deodorant cellulose fiber, and belongs to the technical field of fiber production. Firstly, cellulose fiber is subjected to pretreatment by alkali liquid; impurities such as grease on the fiber surface are removed; meanwhile, swelling treatment on the fiber is completed; secondly, soft water is injected, AMPS and AA are added; after uniform stirring,SDS is added; the preparation of a copolymerization mixed liquid is completed; the preparation is convenient; the copolymerization mixed liquid is more uniform; the process control is realized; finally, the treated cellulose fiber and the copolymerization mixed liquid take copolymerization reaction under the initiating effect of ceric ammonium nitrate; a deodorant cellulose fiber product is finally obtained. The deodorant product is prepared by a copolymerization grafting method; the damage to the fiber by the method is small; the fiber strength reduction cannot be caused; the hand feeling ofthe fiber cannot be destroyed; the deodorant fiber can be cyclically used for many times; the characteristics of the color, the texture and the like of the fiber cannot be changed; the market requirements are greatly met, so that the life quality of people is improved.

The invention relates to a method for preparing a binderless ZSM-5 / beta composite zeolite molecular sieve, which mainly solves the problems that two types of crystal seeds are required for adding in the traditioanal method for preparing the binderless composite zeolite molecular sieve and the preparation method is complex. According to the invention, a Si and Al raw-material and a beta zeolite molecular sieve are mixed for forming, then the Si and Al raw-material besides beta zeolite molecular sieve is selectively conversed to the ZSM-5 zeolite molecular sieve, so that the binderless ZSM-5 / beta composite zeolite molecular sieve is formed. The technical scheme better solves the problems, and can be used in industrial production of the binderless ZSM-5 / beta composite zeolite molecular sieve.

The invention discloses a preparation method of red hard glass. The preparation method of the red hard glass comprises the following steps of accurately weighing KNO3, K2SO4, KOH, Cu2O, SnO, FeO, CoO, FeSO4.7H2O and water according to a mass ratio of (3 to 9): (3 to 5): (1 to 4): (8 to 15): (5 to 9): (3 to 5): (1 to 2): (5 to 9): (5 to 15), carrying out mixing ball milling to obtain coloring paste, uniformly coating the coloring paste on the surface of cleaned hard glass, carrying out heat treatment, and scrubbing to remove the redundant coloring paste on the surface of the cleaned hard glass and to obtain the red hard glass as a sample. Through exchange of Cu<+> ions and K<+> ions, a diffusion rate of the Cu<+> ions in the cleaned hard glass as a sample is improved. The red hard glass obtained by the preparation method has a uniform color, stable quality and a smooth and bright surface. The preparation method of the red hard glass can be controlled easily, avoids secondary reduction treatment on a sample, and has short sintering time.

The LiCoO2 type negative elective electrode possessing the compound structure is prepared from the substrate powder of the negative electrode, the organic matter and the inorganic pore creating materially bu using the strip casting method. The structure formula of the power of the negative electrode is expressed as follows: LiCo1-xMxO2, here M is one or more among earthy elements Be, Mg, Ca or Sr; x is equal to 0.05-0.10. The proportioning by weight between the powder of the negative electrode and the organic matttter as well the inorganic pore creating material is 6:1-3. The invented negative electrodes decrease the solubility of the negative electrode in the molten carbonate greatly and increase stability as well as prolong the service life of the batties. Moreover, the electric conductance of the negative electrodes is increased.
