The key to the composite of wood and ceramic materials is whether a "cross-linking" can be formed between the cellulose of wood, as shown in the following figure. If cross-linking can be formed, it will definitely promote the improvement of wood properties. The intrinsic connection between organic wood and inorganic ceramic materials and the theoretical basis for their composites. Carbon and silicon are widely distributed in nature, and they have some inherent connection. Therefore, these two elements have certain similarities and are the most important elements that make up organic matter, while they are one of the important inorganic elements that make up the earth's crust.
There is an interdisciplinary field between organic chemistry and inorganic chemistry, called organosilicon chemistry. In this field, in order to achieve the goal of composite between wood and ceramic materials, ceramic materials must be introduced into the porous fiber structure of wood. Due to the poor heat resistance of wood, conventional high-temperature sintering methods cannot be used for the ceramic process. Therefore, Sol gel curing method similar to organic resin is introduced.
Firstly, prepare a liquid ceramic that is soluble in water, immerse it into the wood structure, and react with the wood material under certain conditions to crosslink the wood cellulose. Under mild conditions such as lower temperatures, it does not damage the acidity or alkalinity of the wood structure, allowing the ceramic to solidify, thereby achieving the composite of wood and ceramic materials.
When the concentration of silica in sample solutions such as clay and fly ash is high, it is easy to generate calcium silicate precipitates. Therefore, it should be concluded in the acidic solution before dilution. With the development of cement industry production technology, the requirements for the quality of cement products are becoming higher and higher. The accuracy of cement chemical analysis results is the key to ensuring the stability of cement quality. How to improve the level of cement chemical analysis? We believe that enterprise leaders must realize that the key to improving product quality lies in improving the quality of laboratory work, and chemical analysis is a part of cement enterprise laboratories. Therefore, it is required that all enterprises must pay attention to the overall improvement of laboratory level.
Regular business training should be provided to laboratory technicians to learn theoretical foundations, unify operating methods, master key operating points, and conduct business assessments. Pay attention to the implementation of new standards, analyze and improve existing problems in a timely manner, and continuously improve the level of chemical analysis. From the comparison analysis results of cement chemical analysis over the years, it can be seen that the qualification rate of each analysis result has improved compared to the previous one. Therefore, regularly conducting chemical analysis comparisons is an effective way to improve the level of cement chemical analysis in the province.
