To address the problems of wall collapse, cuttings slurrying, and scaling on the inner wall of the drill pipe, which often occur in small-diameter diamond wireline core drilling, the inhibition properties of polyvinyl alcohol (PVA) was investigated, and the formulation of solids-free drilling flu...
The invention belongs to the field of process analytical technology, in particular to the method of producing polyvinyl alcohol solution and a polymerization degree of near-infrared spectroscopy for rapid detection. 具体的说是根据高分子化合物对近红外光产生特征吸收的原理,利用近红外光谱分析技术,得到聚...
PURPOSE:To obtain a base film material whose one side indicates water solubility over a long period of hour and which is dissolved or dispersed in a short period of hours when water is permeated through the other side thereof by laminating the polyvinyl alcohol having a specific saponification de...
An ultralight graphene oxide (GO)/polyvinyl alcohol (PVA) aerogel (GPA) is proposed as a new class of acoustic materials with tuneable and broadband sound absorption and sound transmission losses. The interaction between GO sheets and PVA molecules is exploited in our environmentally friendly manufact...

Abbas and Khan [112] used a FL model to predict the compressive stress-strain behavior of hybrid steel-polyvinyl-alcohol fiber-reinforced concrete and found reasonable support for the model. To predict the bond behavior of lightweight concrete, Arslan et al. [113] employed an FL model based ...
Polyvinyl alcohol and aminated cellulose nanocrystal membranes with improved interfacial compatibility for environmental applications 2022, Environmental Research Citation Excerpt : Then, ethylenediamine of equal volume with the addition of distilled water and refluxed for 8 h. After refluxed, the Am-CNCs ...
The miscibility attributes of PLP/polyvinyl alcohol (PVA) and PLP/hydroxypropylmethylcellulose (HPMC) blends were examined by viscometry and by other advanced analytical tools for different weight proportions. It is shown by the viscometry that the PLP/HPMC and PLP/PVA form an immiscible blend ...
A method is considered for determining concentrations of components in solutions of two electrolytes with one common ion. We used optical micrometry by measuring the degree of swelling of granules of crosslinked polyvinyl alcohol in a test solution. To determine the concentration, the test solution ...
