LIQUID ABSORBING CORE FOR HEATING TRANSPIRATION

摘要

PURPOSE:To obtain a liquid absorbing core having uniform particle size distribution and uniform voids and also having the fixed transpiration efficiency and heating transpiration amount of a medical fluid by infiltrating a solution of a partial hydrolysate of a silicon alkoxide in a porous body formed by sintering spherical or almost spherical thermosetting phenol resin powder at specific temp. CONSTITUTION:A liquid absorbing core for heating transpiration is constituted by infiltrating a solution of a partial hydrolysate of either one of ethyl silicate, methyl silicate and propyl silicate (silicon alkoxides) in a porous body formed by sintering a spherical or almost spherical thermosetting phenolic resin powder having a particle size of 5-50mum and a short/long diameter ratio of 1 or about 1 at temp. from the decomposition point to 100 deg.C by a coating or immersing means. Particle size distribution becomes sharp and constituted voids become uniform and the capillary rising speed and heating transpiration amount of a medical fluid are fixed while effective and stable transpiration effect is continued over a long period of time and a raw material is inexpensive and mass production is possible and this liquid absorbing core can inexpensively be provided.
