Abstract

The invention belongs to the technical field of medical materials, and particularly relates to a preparation method of an X-ray transmitting medical plate, a plate and application. The preparation method comprises the steps of raw paper preparation, melamine impregnated paper preparation, phenolic resin impregnated paper preparation and pressing. According to the technical scheme, an expensive X-ray transmitting carbon fiber plate is replaced with the composite plate formed by laminating the melamine impregnated paper and the phenolic resin impregnated paper, the plate which is high in X-ray permeability, low in formaldehyde release and capable of meeting the requirements of medical plates in mechanical strength is obtained through selection of technological methods and parameters, and dueto the fact that the cost of the plate is controllable, the X-ray transmitting medical plate can be widely applied to a transfer bed, and non-moving X-ray detection is realized.

Description

technical field [0001] The invention belongs to the technical field of medical materials, and in particular relates to a preparation method, a board and an application of an X-ray transparent medical board. Background technique [0002] X-rays are electromagnetic waves with extremely short wavelengths and high energy. X-rays are used in medical diagnosis, mainly based on the penetration, differential absorption, photosensitivity and fluorescence of X-rays. When X-rays pass through the human body, they are absorbed in different degrees. For example, the amount of X-rays absorbed by bones is more than that absorbed by muscles, so the amount of X-rays after passing through the human body is different, which carries the density distribution of various parts of the human body. Information, the strength of the fluorescent effect or photosensitive effect caused on the fluorescent screen or on the photographic film is quite different, so shadows of different densities will be displ...
