Powder Blends(粉末混合物)研究综述
Powder Blends 粉末混合物 - Results It was found that all FLX-powder blends have good flow properties; all the prepared tablets complied with the pharmacopeial requirements for the unity of content, weight, friability, and hardness. [1] Laboratory scale, Ketoprofen sustained release inert matrix tablets were manufactured using Kollidon® SR as matrix formator, by direct tableting of powder blends. [2] HPT deformation of powder blends and BM powders leads to an exorbitant increase in hardness or an unusual fast formation of a σ-phase and therefore impede successful processing. [3] Powder blends, especially bimodal ones, can exhibit higher packing densities and changes in flowability compared to their monomodal constituents. [4] Aiming at filling this gap, in this communication we report on the influence of MA mode on the microstructure of TiC–20% Cr(Ni) composites prepared by forced SHS compaction from activated Ti–C–Cr(Ni) powder blends. [5] The aim of the study is to investigate how the formulation of chewable xylitol-sorbitol tablets affects the properties of the powder blends and the tablets in an environment of different relative humidity levels. [6] In this study, a mid-infrared (MIR) quantum cascade laser (QCL) spectroscopy-based protocol was performed to quantify ibuprofen in formulations of powder blends and tablets. [7] Following the HEBM of powder blends, annealing was performed at 1600 °C for 16 h under Ar atmosphere. [8] Melt-degradation transitions may be re-purposed for the measurement of amorphous content in powder blends, and they have potential for evaluating disorder more generally. [9] Powder blends were characterized in terms of homogeneity, flow properties, sprayability, in vitro biocompatibility, permeability and mucoadhesion. [10] Powder blends were prepared by direct compression (DC), wet granulation (WG) and hot-melt extrusion (HME). [11] In this study, the surface of AISI H13 steel was borided with powder blends of B4C and NaBF4 using the powder-pack method at 800, 900 and 1000 °C for 2, 4 and 6 h. [12] This study demonstrates that the feed frame is an ideal location for monitoring the drug concentration of powder blends for CM processes. [13] Quartz ceramics with a uniform/gradient distribution of BaTiO3 (U/G–SO–BTO) are fabricated by cold pressing a powder blend with BTO followed by sintering and using a combined technique of spreading the powder blends with gradually increased BTO layer–by–layer and sintering. [14] Tablets were prepared by direct compression of powder blends, or propranolol HCl was first granulated with one of the matrix-forming polymers (1:1) followed by compression with carbamazepine and matrix former. [15] Of particular challenge is the powder blends with low drug loads (<5% w/w) where the measurement of the signal-to-noise and, in turn, precision limit the ability of the method. [16] The aim was to obtain the first basic information concerning the behavior of such powder blends during LBM processing and the resulting material properties. [17] Prior to compression, powder blends were evaluated in order to check their flow and compression properties. [18] We observed that some of the acid modifiers catalyze crosslinking of xanthan gum during accelerated stability studies in powder blends, which significantly decreases the viscosity of the corresponding constituted suspension, resulting in poor suspendability and dose inaccuracy. [19] With these powder blends, the effect of a reduction of the filling volume of a three chamber feed frame on the powder residence time was investigated. [20] Flowability tests of the powder blends were performed before compression; these test took into account such physical parameters as bulk density, tapped density, angle of repose, compressibility index, and Hausner's ratio. [21] 1 wt % vitamin-E and irradiated these powder blends (XPE). [22] All studied parameters were found to have substantial effects on flow properties of powder blends. [23] Partial Least Squares (PLS) calibration models were constructed using the same powder blends for the two inlet interfaces and using the outlet granules for the outlet interface. [24] The overall goal of this contribution is to adjust the typical deformation mechanisms of HMnS and therefore the mechanical properties by using powder blends. [25] In the current study, the surface of AISI D2 steel was coated with the powder blends of ferro-vanadium (Fe-V) and ferro-chromium (Fe-Cr). [26] The second latent variable was related to changes in concentration of microcrystalline cellulose and lactose in the powder blends. [27] Percolation theory provides a statistical model which can be used to predict the behaviour of powder blends based on particle-particle interactions. [28]结果发现FLX-粉末共混物均具有良好的流动性;所有制备的片剂均符合药典对含量、重量、脆碎度和硬度统一的要求。 [1] 实验室规模的酮洛芬缓释惰性骨架片剂是使用 Kollidon® SR 作为骨架形成剂,通过粉末混合物的直接压片制成的。 [2] 粉末混合物和 BM 粉末的 HPT 变形导致硬度过度增加或 σ 相异常快速形成,因此阻碍了成功加工。 [3] 与单峰成分相比,粉末混合物,尤其是双峰混合物,可以表现出更高的填充密度和流动性变化。 [4] 为了填补这一空白,在本次交流中,我们报告了 MA 模式对由活化的 Ti-C-Cr(Ni) 粉末混合物通过强制 SHS 压实制备的 TiC-20% Cr(Ni) 复合材料微观结构的影响。 [5] 该研究的目的是研究咀嚼木糖醇-山梨糖醇片剂的配方在不同相对湿度水平的环境中如何影响粉末混合物和片剂的性质。 [6] 在这项研究中,执行基于中红外 (MIR) 量子级联激光 (QCL) 光谱的协议来量化粉末混合物和片剂配方中的布洛芬。 [7] 在粉末混合物的 HEBM 之后,在 Ar 气氛下在 1600°C 下进行 16 小时的退火。 [8] 熔融降解转变可以重新用于测量粉末混合物中的无定形含量,并且它们具有更普遍地评估无序的潜力。 [9] 粉末混合物的特征在于均匀性、流动性、喷雾性、体外生物相容性、渗透性和粘膜粘附性。 [10] 通过直接压制 (DC)、湿法制粒 (WG) 和热熔挤出 (HME) 制备粉末混合物。 [11] 在这项研究中,AISI H13 钢的表面用 B4C 和 NaBF4 的粉末混合物在 800、900 和 1000 °C 下使用粉末包覆法硼化 2、4 和 6 小时。 [12] 这项研究表明,进料架是监测 CM 工艺中粉末混合物药物浓度的理想位置。 [13] 具有均匀/梯度分布 BaTiO3 (U/G–SO–BTO) 的石英陶瓷是通过冷压与 BTO 的粉末混合物然后烧结并使用逐渐增加的 BTO 层分散粉末混合物的组合技术制造的。层和烧结。 [14] 通过直接压缩粉末混合物制备片剂,或者首先用一种形成基质的聚合物(1:1)将丙醇HCl颗粒制成,然后用卡马西平和基质以前压缩。 [15] 特别具有挑战性的是低载药量 (<5% w/w) 的粉末混合物,其中信噪比的测量以及反过来的精度限制了该方法的能力。 [16] 目的是获得关于这种粉末混合物在 LBM 加工过程中的行为和由此产生的材料特性的第一个基本信息。 [17] 在压缩之前,对粉末混合物进行了评估,以检查它们的流动和压缩性能。 [18] 我们观察到,在粉末混合物的加速稳定性研究过程中,一些酸改性剂会催化黄原胶的交联,这会显着降低相应构成的悬浮液的粘度,导致悬浮性差和剂量不准确。 [19] 使用这些粉末混合物,研究了减少三腔进料框架的填充体积对粉末停留时间的影响。 [20] 粉末混合物的流动性测试在压缩前进行;这些测试考虑了诸如体积密度、振实密度、休止角、压缩指数和豪斯纳比等物理参数。 [21] 1 wt% 的维生素 E 并辐照这些粉末混合物 (XPE)。 [22] 所有研究的参数都被发现对粉末混合物的流动性能有很大的影响。 [23] 偏最小二乘法 (PLS) 校准模型是使用相同的粉末混合物构建两个入口接口并使用出口颗粒作为出口接口。 [24] 这一贡献的总体目标是通过使用粉末混合物来调整 HMnS 的典型变形机制,从而调整机械性能。 [25] 在目前的研究中,AISI D2 钢的表面涂有钒铁 (Fe-V) 和铬铁 (Fe-Cr) 的粉末混合物。 [26] 第二个潜在变量与粉末混合物中微晶纤维素和乳糖浓度的变化有关。 [27] 渗透理论提供了一种统计模型,可用于基于粒子-粒子相互作用预测粉末混合物的行为。 [28]

[4] The present study describes the adaption of rapid alloy development in laser powder bed fusion (LPBF) by using elemental powder blends. [5] 5 multi-principle alloy from elemental powder blends using SEBM technique is achievable, but the process parameter optimization rather than post-process heat treatment should be performed to reduce the porosity of samples.

Two Powder Blends
Therefore, two powder blends based on microcrystalline cellulose, one of them serving as a plain powder blend (MCC blend) and the other blend (tracer blend) spray colored with an indigo carmine solution by a fluid bed granulator, were used. [1] We applied the methodology to evaluate the powder flow risks during drug product manufacturing campaigns, where two powder blends with distinct flow behavior were discharged from a 200-L bin. [2]因此,使用了两种基于微晶纤维素的粉末混合物,其中一种用作普通粉末混合物(MCC混合物),另一种混合物(示踪剂混合物)通过流化床制粒机用靛蓝胭脂红溶液喷涂着色。 [1] 我们应用该方法来评估药品生产活动期间的粉末流动风险,其中两种具有不同流动行为的粉末混合物从 200 升的容器中排出。 [2]

Different powder blends of pure Ti mixed with either Al or Cu, as the sacrificial powder, with varying volumetric fractions were analysed. [1] In the present work, 4 different powder blends were prepared, processed with LBPF and characterized to reveal the relationships between the particle size distribution (PSD), the powder morphology and their effect on the rheology, powder bed density, bulk density, microstructure and chemical homogeneity.
