平板玻璃集装化运输成效显著 今年将推广到总产量的百分之十

今年六月中,建材部供销分局与铁道部货运处在洛阳联合召开了全国玻璃集装工作会议,就集装箱、架的标准化、定型化和使用管理问题进行研究讨论。玻璃集装化运输在国际上据说已有一百年历史。我国从1979年开始试验,到1980年蚌埠玻璃厂采用集装运输占总产量40％,洛阳玻璃厂浮法玻璃基本实现集装化。秦皇岛耀华玻璃厂、旅顺玻璃厂等也搞了集装运输。

太阳能光伏组件用镀膜玻璃耐磨性能检测设备的研发

太阳能光伏组件用镀膜玻璃是太阳能组件的关键零部件之一,在沙尘地区使用时玻璃膜层要受到沙尘的破坏,并且在生产、运输、装配、维护保养时会受到损伤。通过对太阳能光伏用镀膜玻璃的耐磨性能试验方法及其检测设备的研究,能提高生产企业在产品设计、工艺配方、生产制造、质量控制中的技术水平,提升生产企业的产品质量和竞争力。     

能源企业危险区域中综合安全技术的应用

能源的生产、运输与储存具有周期性长、危险性高等特点,尤其部分能源需要进行地下开采,例如石油、煤炭等,对安全技术和设备的要求较高。液压支架是井下支护工作的重要组成部分,但在施工前,需要根据煤(岩)层的地质条件,对支护强度进行验算。米山煤业对15113工作面采用6架ZZG6800/19/38型过渡支架和94架ZZ6800/19/38型液压支架对工作面顶板进行支护,并制定了完善的顶底板安全管理措施,对煤矿安全高效的生产提供了安全的技术保障。     

我厂配料工段的改造

我厂是一个生产玻璃瓶罐的老厂,主要产品是翠绿色的啤酒瓶,年产量是4万5千吨。厂里原有两座横火焰玻璃熔炉,熔化面积分别为47m~2和60.5m~2,每天熔化玻璃液量共145吨。成形机械是7台林取-10型制瓶机。在全部生产过程中,玻璃的熔化和成形工艺基本已实现机械化连续生产,唯原料车间的生产比较落后,而改造前的配料工段又是原料车间中最落后的一个环节,设备简陋,原料的运输、称量等工作多是靠人工操作完成,不但劳动强度大,工作条件也极差,车间内到处粉尘飞扬,硅粉尘严重地危害工人的健康。为改变配料工     

谈谈煤气炉的选型

《玻璃》编辑部:请允许我谈一个有关节能的重要问题——煤气炉的选型.发生炉煤气仍是玻璃生产的主要燃料.我国玻璃行业现用的自动化煤气发生炉基本有两种:即AД-13型,威尔曼炉(或称?3米煤气炉).根据我对威尔曼炉多年的操作经验和对其他厂AД-13型炉的实际调查,我认为威尔曼炉具有结构合理、适应性强、操作方便、煤气质量好、灰渣含碳量低等优点,值得在玻璃行业中推广使用.

用Excel计算玻璃木箱包装料的探讨

玻璃生产企业产品的包装在成本中所占的比重较大。其包装主要分为钢制集装架包装和木箱包装两种。钢制集装架包装虽可以重复使用,但用户需交纳一定数量的押金,将空集装架返回厂家后,才可将押金取回,这样一方面造成用户流动资金的占用,另一方面返回空集装架需要烦琐的手续,又要耗费用户的时间和精力。在日趋激烈的市场竞争中,玻璃生产企业为了自身生存的需要,大量使用木箱包

Mineral nutrition of slash pine in subtropical Australia. III. Relationships between foliar P concentration and stand growth

Foliar P concentration of slash pine was significantly related to the stand growth in the first 11.5 years. The relationship between foliar P concentration and total stand growth at foliar sampling improved as the plantation aged with coefficient of determination (R²) increasing from 0.14–0.15 at age 3.3 years to 0.56–0.65 at age 9.6 years. However, only 12–18% of the variation in total stand growth was explained by foliar P concentration at age 11.5 years when additional 40 kg P ha^–1 was applied to the stands at age 10 years. This suggests that caution should be exercised in interpreting the foliar P concentrations of the established stands which had received application of P fertilizer just prior to foliar sampling. Periodic stand growth was more closely related to the foliar P concentration than total stand growth. Basal area and volume periodic annual increment (PAI) was better related to the foliar P concentration than height PAI.Optimum foliar P concentration, at which the maximum stand growth was obtained, was between 0.093% and 0.110%. The optimum foliar P concentration for height PAI immediately prior to foliar sampling decreased from 0.097% at age 3.3 years to 0.070% at age 9.6 years. Critical foliar P concentration at age 9.6 years, at which 90% of the maximum basal area growth was obtained, was between 0.066% and 0.070%. Both optimum and critical foliar P concentration might decrease as the plantation aged.     

Influence of Drift Velocity and Distance Between Jet Particles on the Penetration Depth of Shaped Charges

The penetration depth of shaped charge jet into target is strongly affected by the stand‐off. The penetration process terminates even when the jet velocity is still high, and the penetration capability of jet particles degrades after jet breakup at a large stand‐off. This work presents an analytical model to describe the radial drift velocity and distance between jet particles, which leads to decreased penetration depth. The results show that jet particles with low drift velocity impact the crater wall easily. Furthermore, the jet particles cannot reach the crater bottom to increase depth because the crater diameter generated by the jet is quite small. Moreover, the distances between jet particles also play an important role in penetration depth under the influences of strain hardening of target, as well as tumbling and dispersion of jet particles. The radial drift velocity and distance between jet particles are investigated by applying the model to non‐precision charge and precision charge penetrations into target at different stand‐offs. The cutoff jet velocity and cutoff penetration velocity also are determined based on the analytical model. With increased stand‐off, the cutoff jet velocity increases, and the cutoff penetration velocity is almost constant. This result is proven by a number of experiments. The stand‐off curves of two charges are also calculated, and results are in good agreement with experiments. The stand‐off curve can be determined with only two or three experiments using the proposed method. Notably, jet particles should have a slow drift velocity and great penetration capability after breakup for suitable shaped charge.

Mineral nutrition of slash pine in subtropical australia. I. stand growth response to fertilization

Fertilization at plantation establishment and later age is often required to maximize stand growth of slash pine (Pinus elliottii) in subtropical Australia. A field experiment was conducted to examine stand growth response of slash pine in the first 11.5 years of plantation following (1) initial fertilization at plantation establishment with phosphorus (P) at 11, 22, 45 and 90 kg P ha^–1 which were either banded or broadcast in the presence or absence of basal fertilizers containing 50 kg nitrogen (N) ha^–1, 50 kg potassium (K) ha^–1 and 5 kg copper (Cu) ha^–1 and (2) additional application of 40 kg P ha^–1 at age 10 years.The initial P fertilization significantly increased the stand growth in the first 9.6 years. The P banded application was more effective in improving the stand growth than the P broadcast application. Application of the N, K and Cu basal fertilizers did not affect the stand growth. Overall, 53–73% of the variation in basal area and volume growth in the first 9.6 years was explained by the initial P fertilization, indicating that P deficiency was the major factor limiting the stand growth under the experimental conditions. Optimum plantation age, at which the maximum periodical annual increment (PAI) of basal area was obtained, increased from age 10.9 to 12 years when the initial P rate increased from 11 to 90 kg P ha^–1. Application of additional 40 kg P ha^–1 at age 10 years resulted in a further improvement in the stand growth at age 11.5 years. With 66% of the variation in basal area PAI between ages 9.6 and 11.5 years, 50% was explained by the initial P fertilization and 16% by the additional P applied at age 10 years. Similarly, 51% and 12% of the variation in volume PAI were attributed to the initial P fertilization and the additional P application, respectively. This highlights the need of refertilization with P on some established stands of slash pine at later ages.
