我国的工业房屋建筑需求日益增加.考虑到工业房屋建筑内部多有大型设备,人们越来越重视其安全性及抗震性能.房屋的检测鉴定工作存在于房屋整个寿命期限的各个阶段.其中,安全性及抗震性能鉴定具有关键作用.本文基于工业房屋的安全性及抗震性能鉴定进行数据分析.

农村地区砖混结构较普遍.大量砖混结构的民宅及公共建筑年久失修,存在安全风险.对有潜在安全风险的房屋进行安全性鉴定,可为后期房屋的加固提供科学指导依据.

无规共聚聚丙烯(PP-R)管材行业发展迅速,但是产品质量不尽如人意.通过近年对838个PP-R管产品的抽查检测,发现了一些质量问题.本文分析不合格率低的几点原因,对PP-R管行业存在的问题提出看法.

由于人造草坪具有更耐磨、易打理、使用寿命长等优点,越来越多的足球场选用其替代天然草坪来进行场地铺装.人造草坪分为免填充型人造草和填充型人造草.填充型人造草需搭配一定填充比的石英砂和弹性颗粒,并配有弹性垫,以达到不同效果的运动性能,匹配不同功能的足球场.本文探究填充不同配比的石英砂和弹性颗粒对填充型人造草坪冲击吸收、垂直变形性能的影响.结果表明,当配有弹性垫的人造草坪填充石英砂25kg/m2、弹性颗粒8kg/m2时,其运动性能较好.

酚醛泡沫以甲阶酚醛树脂为主要原料,由于其优异的保温和阻燃性能在保温领域具有广阔的应用前景.但是,酚醛泡沫在成型过程中通过酸性(催化)固化剂固化成型,金属材料与泡沫体接触时容易受到腐蚀.为了降低金属被腐蚀的可能性,在不影响酚醛泡沫其他优良性能的前提下,通过选择合适的碱性填料、用酯固化作用取代酸固化剂、合成吸酸剂等方法降低酚醛泡沫的酸性.

针对塑胶运动场地面层中短链氯化石蜡(SCCPs)含量的测试,本文通过电子捕获负化学离子源-气相色谱-质谱法(ECNI-GC-MS)对萃取液净化方式的选择和中链氯化石蜡(MCCPs)可能导致的干扰进行了分析,并对测试方法进行了详细验证.研究显示,样品萃取液采用浓硫酸净化方式的平均回收率可达90％以上,且样品中可能存在的MCCPs对测试结果无干扰;方法标准工作曲线线性良好,方法检出限为0.028 g·kg-1,定量限为0.1 g·kg-1,重复性试验相对标准偏差RSD(n=6)在3.0％-5.O％之间,加标回收率在90％-105％之间.

改革开放以来,整体地坪在我国有着长足地发展,目前已经使用在多个领域,同时,整体地坪标准体系的建设也越发的健全.本文综述了整体地坪的标准体系的建设状况,列举了与整体地坪相关的基础标准、设计规范、施工及验收规范的标准名称,分析了三者之间的关系,指出了标准体系的发展方向.

胜利油田已经进入开采后期,广泛应用三次采油技术,使得采出原油含水量增高(有些片区甚至达到95％以上)、成分复杂(含有水处理剂以及集合物).原油中含有的天然乳化剂、开采过程中析出天然气对原油的搅动、地面集输和处理过程中管件对原油的搅动,共同促使乳状液形成.油水乳状液如不及时处理,在联合站内存积下来,随着时间稳定性增强,形成老化油,对原油处理流程及设备有较大影响.本文将从老化原油的特性出发,探讨油田联合站对老化油的处理技术应用.

At present, there are many types of waterproof coiled materials on the market, the performance of which is different, and the quality is uneven. The article mainly studied the SBS modified bituminous sheet materials and the polyethylene polypropylene fiber composite waterproof coiled materials, and compared the composition and performance of these two types of materials. At the same time, combined with their application status and deficiencies, some suggestions were provided for construction selecting materials.

With the development of economy and the improvement of living quality, the quality of the construction project has been got more and more attention. The Waterproofing Rolled Material has been regarded as the first barrier to the construction project, of which the quality cannot be ignored. The development of building waterproof material industry in recent years has been introduced in this paper. On the base of 8 years’ national supervision and spot check data, the quality status has been analyzed, and several possible reasons has been found out. Some measures and suggestions that must be taken in the work of quality supervision in the future has been suggested in this paper.

At present, GB/T28863-2012 has been implemented formally. This report analyses the principle of small probability events, it not only states the origin of the commodity quality’s supervision and sampling inspection procedures, but also it presents the scientific basis of the sampling design schemes. Introduce the specific sampling procedures of the commodity quality’s supervision and sampling inspection procedures, and the utilisation of new sampling procedure in building material. In addition, the report also explains the Applicability of new sampling procedure in building material’s supervision and inspection. It raises some view according to the actual usage.
