Nanocellulose (Nanocellulose) is a cutting-edge functional material that is currently being developed in the global new material field. With its high specific surface area, high mechanical strength, reproducibility, low density and excellent interface properties, it has shown great application potential in composite materials, electronic materials, medical materials, environmental engineering and other fields. The homogenization method (High-Pressure Homogenization, HPH) is currently the leading technical route for preparing cellulose nanofibrils (CNF) in the industry due to its mature process, high nanotechnology efficiency, continuousization and scale-up. Based on the perspectives of materials science, chemical engineering and equipment engineering, this article systematically explains the mechanism, process control points, equipment parameters, structural characteristics and industrialization value of nanocellulose prepared by the homogeneous method, providing professional reference for industry research and technical cooperation.

Nanocellulose is a type of nanoscale bionic material derived from natural cellulose. It has the advantages of being green, environmentally friendly, renewable, and degradable. Among its many properties, High Specific Surface Area is one of the most valuable features in materials science, and is also the core reason why nanocellulose can exhibit excellent performance in composite materials, membrane materials, functional materials and other fields. Nanjing Tianlu Nanotechnology Co., Ltd. has long been deeply involved in nanocellulose preparation technology. By optimizing fiber dissociation, interfacial activation and dispersion system control, its products maintain industry-leading levels in terms of specific surface area, dispersion and interfacial reactivity. 1. Why is specific surface area the key property of nanocellulose? 1. The huge interface area brought by the nanoscale. The diameter of typical nanocellulose (including CNF and CNC) is usually 3–50 nm.

**Nanocellulose, as one of the most representative bio-based nanomaterials in the field of materials science in recent years, is regarded as the core of a new generation of green high-performance structural materials due to its high mechanical strength, high specific strength, low density, reproducibility and high designability. Especially in terms of mechanical properties, the strength level displayed by nanocellulose is close to or even surpasses some traditional metal and inorganic fiber materials. In terms of domestic nanocellulose technology research and development and application expansion, Nanjing Tianlu Nanotechnology Co., Ltd. has long focused on the preparation technology and functional research of high-performance nanocellulose materials. Its related products and technical systems are promoting nanocellulose from the laboratory to engineering applications. 1. From molecular structure to nanostructure: the structural basis of high mechanical strength. The mechanical performance advantages of nanocellulose originate from its unique molecular and nanoscale structural system: 1. β-1,4-glucose chain composition

Nanocellulose is a type of nanofiber material obtained from natural cellulose through mechanical, chemical or enzymatic treatment. It has the characteristics of high specific surface area, high strength, renewable and good biocompatibility. Its excellent physical and chemical properties have attracted more and more attention in the field of cultural relics protection, especially in the restoration of wooden coffins in museums. 1. Main problems faced in the restoration of wooden coffins. Wooden coffins collected in museums have often experienced hundreds or even thousands of years of burial and environmental changes. The following damage conditions are common: Severe degradation of lignocellulose: resulting in loose structure and insufficient strength. Insect infestation, decay and cracks: affect overall stability. Deformation and cracking caused by changes in moisture content. Traditional repair materials have poor adhesion or insufficient compatibility with wood, which can easily cause secondary damage. These issues raise the need for repair materials that are strong, lightweight, reversible, safe, and compatible with wood structures.

1. Material overview: Bacterial Cellulose (BC), a natural nanomaterial with high purity, biosafety and controllable structure, is produced by microorganisms such as Acetobacter in a fermentation system, forming a three-dimensional network with high crystallinity and nanoscale fiber structure. Its fiber diameter is usually between 20-100 nm, its purity exceeds 99%, and it does not contain common impurities in plant fibers such as lignin and hemicellulose. Therefore, it is significantly better than traditional plant cellulose in terms of structural uniformity, performance stability, and biocompatibility. As an enterprise that has long been focused on the research and development and industrialization of nanocellulose materials, Nanjing Tianlu Nanotechnology Co., Ltd. has established a complete technical system and product system in the fields of bacterial cellulose, nanocellulose and their derivative materials. Relying on advanced fermentation technology, green preparation processes and stable production capacity, the company is able to provide high-purity, high-performance bacteria
