目前能用于解剖学技术的铸型方法,有溶剂挥发后凝固成型法和化学反应成型法。在溶剂挥发后凝固成型法当中,认为过氯乙烯是比较理想的铸型材料,是铸型标本首选的填充剂。其优点是支撑力强、柔韧性好、成型美观、价格低廉、来源广泛、化学性能和物理机械性能都比较稳定[1-3]。但 Currently available casting methods for anatomical techniques include solidification of solvent after evaporation and chemical reaction molding. Solidification in the solvent evaporation after forming method, that perchlorethylene is the ideal casting material, casting sample is the preferred filler. Its advantages are strong support, good flexibility, beautiful appearance, low price, wide range of sources, chemical properties and physical and mechanical properties are relatively stable [1-3]. but
