摘要： A method for detecting a thickness of bonded rubber of a carbon black in a natural rubber based for reinforcement performance is provided. An ultra-thin frozen microtome to prepare a sample, a tapping mode of the atomic force microscope is used, and when characterizes the carbon black and rubber composite material, the difference of imaging characteristics between morphological and phase diagrams is used, the characteristics of bonded rubber of carbon black reinforced composite material can be observed to obtain the thickness of bonded rubber, and then influence of bonded rubber on rubber performance and the reinforcement performance of the carbon black in the rubber are analyzed. The method has advantages of simple operation, no need for excessive sample processing, high detection efficiency, clear detection images and high detection accuracy, thereby having better applicability and providing a new method and idea for studying reinforcements of fillers.

摘要： This invention discloses method for feeding Hermetia illucens and used as for preparing composite material of puparium, which comprises the following steps: S1, dry Hermetia illucens pupariums and grind them into powdery, S2, adding powdery of Hermetia illucens pupariums into sodium hydroxide aqueous solution, stirring, separating and filtering, S3, adding the pupariums into hydrochloric acid solution, stirring, separating and filtering; S4, placing the pupariums into sodium hydroxide aqueous solution, stirring, separating and filtering; S5, drying the pupariums, and screening out the granular pretreated powder of the Hermetia illucens pupariums. The invention also disclose preparation method of composite material and thin film of Hermetia illucens pupariums and antibacterial and antimildew additive. The method can effectively improve the yield of chitosan in Hermetia illucens pupariums, and the prepared pupariums powder can be used for preparing polymer composite fibers and thin films of the Hermetia illucens pupariums, thus, the antibacterial effect is greatly improved. A new antibacterial and antimycotic additive can be obtained by compounding the powder of Hermetia illucens pupariums with the powder of oyster shell.
