- 一直这样还是突然这样呢,首先你得确定封口机有没有损坏,如果没有损坏的话,你在用封口机封口之前,要对机器进行预热,大概要3到5分钟,如果天气冷的时候,可能预热的时间更长。另外,封口机上面的温度调节开关是不是打在了合适的位置,如果封口膜比较厚,要把温度调高一点。还有,这个封口的速度,跟封口机的质量也是挂钩的看你的设备是哪家的,不下压分两种情况,,一是不下压,封口膜在转动,那可能是电眼有故障,二是不下压,封口膜也不转动,可能是微动开关或上模马达或主板有故障。温州进诚塑料杯装牛奶灌装封口机

- 旧的机器就要注意清洁一下,感应距离可以调近一点或用颜色深一点的袋子试下,确定是不是感应器的问题。

- 粒度检测方法与优缺点比较 粉末粒度分布的测量方法经过百余年的发展,据统计至少已经发展了上百种,但随着科技的发展,有些方法被逐步淘汰,有些方法得到了改进和发展(如激光散射法、动态光散射等), 并在生产、科研中得到了广泛的应用,现在普遍使用的测量... 粒度检测方法与优缺点比较 粉末粒度分布的测量方法经过百余年的发展,据统计至少已经发展了上百种,但随着科技的发展,有些方法被逐步淘汰,有些方法得到了改进和发展(如激光散射法、动态光散射等), 并在生产、科研中得到了广泛的应用,现在普遍使用的测量方法有筛分法、显微图像法、光透沉降法、激光散射(衍射)法等几种,下面简单介绍几种常用的粒度测量方法。 ▲ 筛分法 是一种具有很长历史的粒度测定方法,筛分法粒度测量是利用一组筛孔大小不同的标准筛将粉末进行筛分,然后对每个筛上样品分别进行称重,进而得到以质量为量纲的粒度分布数据,并可由分布结果计算出如Dv50等其它参数。筛分滶要特点是测量成本低廉,操作简单,但存在着如重复性差,测量时间较长,不能对5um以下的颗粒进行测量等缺点。 ▲显微图像分析法 利用光学或电子显微镜及计算机图像识别技术对颗粒粒度及粒度分布,颗粒形貌进行测量,分析的方法。这种方法不仅能够测量粒度分布而且能够直接观察到颗粒的形状,是目前唯yi的一种可目视的直观测试方法,这种特点也是其它粒度测量仪器所不具备。这种方法的优点是直观、简便、费用低,缺点是由于取样量很少,为使测量结果代表性,必须增加待测颗粒的个数(一般认为测量颗粒的个数应在1000个以上),这就相应啬了测量时间,及测试人员的工作强度,但由于能够对颗粒形貌(如长径比等)进行测量,目前也有广泛应用。 ▲光透沉降法 沉降法粒度测试的理论基础是斯托克司定律和比尔定律。前者给出颗粒沉降速度与粒径的关系,后者阐明光透过率与粒径重量的关系。可简单的描述为:在沉降液中,有若干相同比重的颗粒,如果同一时刻,从同一位置开始下降,则不同直径的颗粒到达测量区的时间是不同的,根据颗粒到达测量区的时间,及光强的强弱,就可以计算出颗粒的粒径,及相应粒径的颗粒在颗粒群中占有的比例。采用此种原理的测量仪器有比较长的使用历史,但随着科技的发展和测量手段的进步,此方法的缺点也日益突出,如测量时间长,重复性误差大等。 ▲ 激光散射法 颗粒测量仪器是以富朗和菲衍射(Fraunhofer diffraction)和米氏散射(Mie scattering)为理论基础。此理论可以简单理解为沿直线传播的平行激光束,在传播过程中遇到颗粒的遮挡后,传播方向发生了改变(即发生了衍射和散射现象),并且大颗粒使激光改变的角度小,小颗粒改变大。(实际上是由于颗粒的遮挡在无限远处形成了一个爱里斑,爱里斑87%的能量集中在ZX亮环,且颗粒直径越大,ZX环越小,颗粒直径越小ZX亮环越大)。如果能在不同角度上接收光能, 对于相应的的角度,其光能是对应直径的颗粒集合发生衍射(散射)造成的,相应其他角度上光能的强弱也就反应了对应直径颗粒在整个颗粒集合中占有的比例。 ▲ 采用激光粒度测量仪器相对于光透沉降粒度测量仪器具有很多优点: 1. 原理先进,并且由于测试过程中没有需要预先设定的参数(如样品比重、介质黏度、环境温度等),及在测量过程中随时改变的条件, 因此测量结果准确、可靠。 2. 测量速度快,测试时间与样品粒度分布无关,典型测试过程一般小于一分钟; 3. 每次测试,多次对样品进行扫描,测试结果重复性好; 4. 进样方式种类多,可适用于各种类样品。 展开

- IFRS13willhelpincreasetransparencywhenentitiesusemodelstomeasurefairvalue,particularlywhenusersneedmoreinformationaboutmeasurementuncertainty,suchaswhenthemarketforanasse... IFRS 13 will help increase transparency when entities use models to measure fair value, particularly when users need more information about measurement uncertainty, such as when the market for an asset or a liability has become less active. IFRS 13 requires entities to disclose information about the valuation techniques and inputs used to measure fair value, as well as information about the uncertainty inherent in fair value measurements (which was of particular concern during the global fi nancial crisis). Some of those disclosures, including the fair value hierarchy, were already introduced in March 2009 through an amendment to IFRS 7 Financial Instruments: Disclosures. Those disclosures have been relocated to IFRS 13. The requirements in IFRS 13 also incorporate the guidance in a FASB Staff Position (FSP) issued in April 2009. 展开

A new kind of TiO2 nanotube array/Ni(OH)2 (TiO2/Ni(OH)2) composite electrode with the storage ability of light energy was prepared by the deposition of Ni(OH)2 on the TiO2 nanotube array, which was synthesized by anodizing Ti foils in an HF aqueous solution. SEM and XRD results showed that Ni(OH)2 particles were well distributed on high density, well-ordered and uniform TiO2 nanotube arrays. The photoelectrochemical properties of the TiO2/Ni(OH)2 electrode were investigated in NaHCO3/NaOH buffer solution (pH 10) by means of UV–vis absorption spectra, cyclic voltammogram (CV) and photocurrent measurements. It was found that the TiO2/Ni(OH)2 electrode was highly sensitive to light and exhibited excellent photoelectrochromic properties. Upon UV irradiation, the photogenerated holes by TiO2 nanotube arrays can oxidize Ni(OH)2 to NiOOH, and thus the TiO2/Ni(OH)2 electrode can be photo-charged by light。1. Introduction Among many visible light photocatalysts, TiO2nanostructures have attracted much attention due to high photocatalytic activ-ity, nontoxicity, chemical stability and huge potential applications [1–6]. The TiO2 nanotube array is one of most attention-getting TiO2nanostructures because of large surface area and outstanding charge transport properties. TiO2nanotube arrays can be utilized in dye-sensitized solar cells[7–9], photocatalysis and hydrogen gas sensing [10]. So far, a variety of methods have been attempted to prepare TiO2 nanotube arrays, such as hydrothermal synthe-sis[11], Langmuir–Blodgett technique [12], solution casting [13] and anodization technique[10,14], etc. Among these methods, the anodization technique has many advantages of low cost, low tem-perature and easy to be scaled up to large-area preparation. Recently, anewkindof photo-functional systemwith theenergy storage ability has been developed by coupling TiO2 photosen-sitive electrode with energy storage materials. In Takahashi and Tatsuma’swork[15],aTiO2/Ni(OH)2bilayer thinfilmwas suggested for the oxidative energy storage. In this case, a redox-activep-type semiconductor Ni(OH)2is coupled withn-type TiO2photocatalyst to formap–njunction,WhenTiO2is illuminatedby light, holesgen-erated at the junction are separated from excited electrons, trans-ported into the bulk of Ni(OH)2and oxidized Ni(OH)2to NiOOH. Therefore, the oxidative energy storage system was constructed 展开

- Withmorethan6millionnewmeasurementchannelssoldlastyear,NationalInstrumentsisaworldwideleaderinvirtualinstrumentation.Engineershaveusedvirtualinstrumentationformorethan25y... With more than 6 million new measurement channels sold last year, National Instruments is a worldwide leader in virtual instrumentation. Engineers have used virtual instrumentation for more than 25 years to bring the power of flexible software and PC technology to test, control, and design applications making accurate analog and digital measurements from DC to 2.7 GHz. This document provides an excellent introduction to virtual instrumentation as well as additional resources for continued research. What is virtual instrumentation? With virtual instrumentation, software based on user requirements defines general-purpose measurement and control hardware functionality. Virtual instrumentation combines mainstream commercial technologies, such as the PC, with flexible software and a wide variety of measurement and control hardware, so engineers and scientists can create user-defined systems that meet their exact application needs. With virtual instrumentation, engineers and scientists reduce development time, design higher quality products, and lower their design costs. 展开

Scanning electron mic... 2.2.1. Physical and physicochemical characterization The particle size distribution of the Ch-zeolite was determined using a laser diffraction equipment (CILASk 1064) and standard wet sieving (Mesh Tylerk series). Scanning electron microscopy (SEM-PHILIPSk XL20) was used for photomicrographs as well as to analyse the Ch-zeolite composition (Energy Dispersion X-ray, EDX). The sample was initially placed in a vacuum chamber for coating with a thin layer (few nanometers) of gold (Au). The specific surface area of the material was measured by the methylene blue technique and by nitrogen gas adsorption methods, with the latter also providing information about particle porosity. In the methylene blue adsorption method, aqueous solutions (50 ml) of methylene blue (100 mg l 1) were agitated using an orbital shaker (Marconik) for an hour at room temperature in the presence of different quantities of the Ch-zeolite (0.05–0.3 g). The suspensions were then allowed to settle for 23 h and the resulting supernatants were centrifuged at 5000 rpm before the analysis of the residual methylene blue concentration. Results obtained correspond to averaged values of three different experiments. The specific surface area was evaluated by the Langmuir model, assuming the formation, at high concentrations, of a dye monolayer and 1.08 nm2 molecule 1, for the cross-sectional area (Van den Hul and Lyklema, 1968). The Ch-zeolite specific surface area was evaluated by the nitrogen gas adsorption method, using automated equipment (Autosorb 1-Quantachrome Instrumentsk), employing multipoint BET isotherm adsorption data fitting. Also from these data, the porosity of the material was evaluated through parameters such as volume of total pores (d < 206 nm), surface area and volume of micropores (d < 2 nm; Micropore Analysis Method). Zeta potential measurements for the natural and ammonia loaded zeolite, as a function of medium pH, were determined using a Zeta Plusk equipment (Brookhaven Instruments). Suspensions (0.01% v/v) of the Ch-zeolite, previously sieved below 37 Am (400 Mesh Tylerk), in a 10 3 mol l 1 solution of KNO3 were used and the medium pH was controlled with the addition of HNO3 (pH< 7) and KOH (pH>7), separately. For the Ch-zeolite saturated with ammonia, suspensions of the material were prepared by the same procedure, except that the sample was loaded with 100 mg NH3–N l 1 of ammonia. 展开
