      化学实验室中进行的实验项目,经常要用到酸、碱、有机溶剂等各类化学药品,所以,一般要求实验台台面材质要耐腐蚀,另外对于某些高温化学实验,实验室台面需要耐高温。
    ?
    ?
      1. 陶瓷台面:陶瓷台面板优点是耐高温,耐腐蚀,绝缘、耐磨度较高,缺点是不耐撞击,抗压性相对较低,台面的光滑度很高。适用于某些高温实验和一些化学实验,当然,如果您的实验中用到氢氟酸,陶瓷台面就不能用了。
    ?
    ?
    ?
      2. 大理石台面:大理石台面的优点是耐高温,可承受温度达到1000℃以上,另外,大理石台面硬度高,不易变形,耐磨性好,承重达到500公斤/㎡,但造价相对高,所以一般用于实验室天平台,高温台台面。

      3. 实芯理化板:实芯理化板是由木质纤维浸渍合成树脂经高温高压制成的板材,表面经特殊的理化处理,造价较低,并且具有耐酸碱腐蚀,耐热,耐磨,抗冲击的优点,大部分普通化学实验室的实验台选择实芯理化板作为实验室台面,但要注意的是,实芯理化板虽耐热但不耐高温,不能长时间承受80℃以上的温度。实芯理化板的耐腐蚀性较大理石台面高一些,但耐久性会比大理石台面稍低。再好的实验台面也需要保养,实芯理化板也如此,如果长时间直接接触到酸、碱性药品或长时间处在高温、潮湿等环境中,理化板的使用寿命会大幅降低。
    ?
    ?
    ?
      4. 环氧树脂板:刚刚说了实芯理化板是很多普通的化学实验室常用台面,但如果想要实验室家具更加耐久,环氧树脂板是个不错的选择。环氧树脂板主要为加强型环氧树脂成份,内外材质一致,可修复性能较强。具有较强的耐酸碱、耐撞击、耐高温能力。但是造价偏高。
