This is a preliminary report of the application of several methods in the making of bamboo pulp. The two-stage soda process and the two-stage sulfate process were first tested. It was found that the pulp obtained by the second process can be better bleached than that by the first process. In order to im-prove the quality of the pulp, the three-stage sulfate process was then applied. It consists of three steps, namely, cooking in water under slight pressure (115℃) for about one hour, digesting in a solution...

This is a preliminary report of the application of several methods in the making of bamboo pulp. The two-stage soda process and the two-stage sulfate process were first tested. It was found that the pulp obtained by the second process can be better bleached than that by the first process. In order to im-prove the quality of the pulp, the three-stage sulfate process was then applied. It consists of three steps, namely, cooking in water under slight pressure (115℃) for about one hour, digesting in a solution of one percent of the cook-ing reagent (HaOH:Na2S=2:l) at 120℃ for two hours, and finally digesting in a 5% solution of the reagent for three hours. This 3-stage method gave a product which is satisfactorily white and was found equally applicable to sev-eral kinds of bamboo used.

本文系将数量制粕法应用於竹材纸粕之初步研究报告,试以二级碱法及二级硫酸盐法蒸解老竹,发现后者竟较前者更宜於竹材,所得硫酸盐竹粕,经漂白后色泽较碱粕为佳,再试以三级硫酸盐法,先以水於微压下(115℃)蒸煮一小时,次於120℃时以1%蒸解剂(NaOH:Na_2S=2:1)稀溶液预行蒸解两小时,最后以5%蒸解剂溶液蒸解三小时,结果可得洁白之纸粕,对於所用数量竹料均极相宜.第三级蒸解之最宜情况,经试验结果,以在160℃时用5%蒸解剂溶液(NaOH:Na_2S=2:1)蒸解3(1/2)小时之成绩为最佳,所得纸粕色泽既白,且漂剂消耗量亦低.作者曾将竹材皮层与心材剥离,分别以三级硫酸盐法蒸解,证明两者所得纸粕,就色泽及漂剂消耗量而言,大致相同,指示前人理论,谓老竹皮层中含有高分子胶质,纸粕不易漂白,似属不确.本试验仅用三种不同地区所产之竹为原料,故三级硫酸盐法是否适用於所有国产竹材,及其最宜蒸解情观是否完全相同,犹待於将来之研究.

In the present investigation, water in bleaching powder was found to play a leading role in determining the stability of the latter. In order to compare the stability of various samples of bleaching powder, we determined the content of the available chlorine before and after a sample kept in a small glass-stoppered tube at 90℃ for 8 hours. The ratio of residual to the original content of available chlorine when expressed in percentage is defined as the index of stability.The samples of bleaching powder and raw calcium hypochlorite investigated in our work contain-ed in the main the following components: Ca(Ocl)_2(S), Ca(OCl)_2·3H_2O(S), CaCl_2·6H_2O(S)and CaCl_2·Ca(OH)_2·H_2O(S). When bleaching powder or raw calcium hypochlorite was thoroughly dried under a vapor pressure of 0.1 mm. Hg at 25°, two of the components were dehydrated according to the following reactions (Figure 5): Ca(OCl)_2·3H_2O(S) = Ca(OCl)_2(S) + 3H_2O(~5mm. Hg) CaCl_2·6H_2O(S)=CaCl_2·H_2O(S) + 5H_2O(~1.0 mm. Hg) and the index of stability attained 100% (Figures 6 and 7). Water which can be removed from a sample under the above conditions is defined as removable water. By the control of amount of the removable water in a sample, the index of stability can be made to vary between 0 to 100%.If we take the percentage of the available chlorine decomposed in an hour at 90 as the rate of decomposition (D %/hr.), the latter seemed to vary linearly with the amount of removable water (W %) (Figure 8). When the samples were heated in a stoppered tube to 90° from 25°, the removable water probably redistributed according to the following scheme: xCa(OCl)_2(S) + y Ca(OCl)_2·3H_2O(S) + z CaCl_2·6H_2O(S) 25° xCa(OCl)_2(S) + (y + (5z)/3) Ca(OCl)_2·3H_2O(S) + z CaCl_2·H_2O(S) 90° Inasmuch as the thoroughly dried samples did not decompose considerably even at 90°, the decomposition of OCl~- seemed to take place almost exclusively in the phase Ca(OCl)_2·3H_2O(S). The linear relationship of D vers. W indicated that the decomposition rate of a sample varied linearly with its content of the component Ca(OCl)_2·3H_2O(S) at 90°. In the light of the above results, an explanation was proposed to account for the decomposition of bleaching powder under the conditions of storage.

本工作肯定,水在漂白粉的稳定性问题中具有极其重要的作用.漂白粉和漂粉精样品在0.1毫米汞柱的蒸气压下可脱去的水称为可脱水.在90°下八小时后样品中有效氯量占原有效氯量的百分数称为其稳定度.稳定度测值指出,样品的可脱水率从0%递增时,其稳定度则从100%递减至0%.根据吸水率-蒸气压图等数据,样品的可脱水主要分布在物相Ca(OCl)_2·3H_2O(S)和CaCl_2·6H_2O(S)中,而在90°下,全部可脱水则集中至前一物相.样品有效氯成分的分解主要在Ca(OCl)_2·3H_2O(S)中,而在Ca(OCl)_2(S)中分解很少.稳定度的数据指出,在90°下,样品有效氯分解率与其中可脱水率成正比,从而亦与其中物相Ca(OCl)_2·3H_2O(S)的含率成正比. 根据上述,作者并从生产实践的意义讨论了漂白粉的稳定性问题.

For the sake of fulfilling the increasing demands on high-pressure vessels, and discussing further on the techniques in their manufacture, we started the research works since the end of 1956.

为了满足国内高压容器的发展的需要,并对制造高压容器的新技术作进一步的探讨,我们进行了以铸钢代替锻钢的研究试验,以解除对高压容器材料的限制。同时也研究运用金属的塑性理论以自动增强高压容器。这种利用材料的塑性性质来进行结构的研究,肯定是一种先进的分析方法,它不但充分发挥了材料的潜力(塑性材料的屈伏点被提高了),而且是正确地估计了结构的真正工作能力。 通常由於铸钢所具有的一定的缺陷,以及作为高压容器时,估计到铸钢在爆破中所可能形成的碎片将有较大的杀伤破坏,因此国外许多文献上都载着铸钢作为容器时的压力限制,甚至有的在根本上就否定了铸钢作为高压容器材料的可能。 我们的试验否定了文献上的规定,现在铸钢的高压容器已受到普遍的欢迎有许多地方则早已把这种价廉、质优、安全、能够很快成批生产的设备投入了生产。
