Quantifying regain conductivity in proppant packs using broken Na-CMC fracture fluid
Journal of Natural Gas Science and Engineering, 2017Abstract An experimental study was performed with the scope of quantifying the regain fracture conductivity in a proppant-packed API RP-61 conductivity cell which was prior injected with broken Carboxyl Methyl Cellulose (CMC) fracture fluid. The initial fracture conductivity measurement was done on a proppant-packed (30/50 CARBOprop type) API RP ...

Key Engineering Materials, 2020
The authors have studied the impact of mechanomagnetic activation (MMA) of the solutions NA-CMC, widely used for mixing water-cement paste, on the structure and properties of cement composites. By the method of dynamic light scattering, the appearance of nanosize particles of grouting fluid’s dispersion phase has been proved. On the base of the results

Vyhodnocení vlivu elektrolytů na CMC pomocí iontově-selektivní elektrody
2010In the rigorous thesis an ion-selective electrode has been utilized to measure CMC of five cationic tensides and to evaluation of an influence of electrolytes on CMC values. Commonly supplied cationic tensides have been used, i. e. benzalkonium chloride, benzethonium chloride, cetyltrimethylamonium bromide, cetylpyridinium chloride and ...

Holzforschung, 2015
Abstract The effect of coatings on paper sheets has been studied. For this purpose gels were prepared from unextracted and extracted bark. The gels represented dispersions of micro- and nanoparticles. The coatings were also prepared from mixtures of gels with chitosan solutions in 1% acetic acid and aqueous Na-carboxymethylcellulose (Na ...

Polimer Semi-Sintetik Berbasis Karbopol, HPMC, dan Na-CMC untuk Patch Mukoadhesif
Bandung Conference Series: PharmacyAbstract. Bukal mucoadhesive patches are an important innovation in drug delivery as they enable rapid drug absorption and bypass first-pass metabolism, thereby improving therapeutic efficacy and patient compliance. The success of a mucoadhesive patch is strongly influenced by the choice of polymer matrix, which plays a crucial role in film formation ...

THE EFFECT OF POZZOLANIC CEMENT SPESIFICATIONS IN ADDITION TO POLIELECTROLIT ON Na-CMC
2006The aim of this study is to examine the effects of Na-CMC on cement as an alternative chemical admixture in the production of cement with metakaolin by using standard cement experiments. The blended cement mortar which was produced by the use of these Na-CMC was affected changes in the physical (specific gravity, fineness, specific surface area ...
