An aqueous solution of y-glycidoxypropyltrimethoxysilane (KH 560) has been prepared by hydrolysis of KH 560 under acidic conditions. The effects of the contents, the types and concentration of the catalyst, and storage time on the properties of the products are discussed. The products have been characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis and particle size analysis. The results show that with 0.5% formic acid as the hydrolysis catalyst, the prepared product has ideal indicators and good storage stability. The KH 560 hydrolysate solution or the pure KH 560 (used immediately after diluted with water) is used to treat the glass fibers respectively, and it is found that the related properties of the treated glass fibers are similar. The physical properties, hairiness, and mechanical properties of the dipped yarn are equivalent to the ring shear performance of NOL, in accord with the requirements. [ABSTRACT FROM AUTHOR]

Neurodevelopmental disorders in children have become a significant global public health concern, impacting child health worldwide. In China, the current intervention model for high-risk infants involves early diagnosis and early treatment. However, in recent years, overseas studies have explored novel preventive early intervention strategies for neurodevelopmental disorders in high-risk infants, achieving promising results. This article provides a comprehensive review of the optimal timing, methods, and intervention models of the preventive early intervention strategies for neurodevelopmental disorders in high-risk infants. The aim is to enhance the awareness and knowledge of healthcare professionals regarding preventive early intervention strategies for neurodevelopmental disorders in high-risk infants, facilitate clinical research and application of such interventions in China, and ultimately reduce the incidence of neurodevelopmental disorders in this high-risk population.
