为了封装土样,全国每年要用相当数量的纱布和腊,在物质上和资金上都是一笔大数字,我组同志经过多次试验,用50%的腊和50%的沥青代替黄腊,用麻纸代替纱布,不但节约资金50%以上,而且质量完全合格,目前我所已大量采用。封后麻纸完全粘于土筒,用刀子在盒盖边一划,就可很容易的揭开;拌和后的“腊”为黑色,应先涂盖顶,稍停再粘标笺,字迹可保持清晰。 In order to encapsulate soil samples, the country uses a considerable amount of gauze and wax each year, which is a large sum of material and financial resources. After several experiments in our group, 50% of wax and 50% of asphalt were used instead of yellow wax , Hemp paper instead of gauze, not only saving more than 50%, and the quality of fully qualified, I have been widely used. After the closure of linen paper completely stick to the soil tube, with a knife in the lid side of a stroke, you can easily uncover; After mixing the “wax” is black, should be coated top, stop and then sticky memo pad , Writing can be kept clear.
