Compression tests revealed that these semi-IPNs were robust materials with compressive modulus between 13.3 and 90.5kPa, the addition of Salecan increased the fracture strain from 71.1% to 88.8%. Rheological measurements play an essential role in quality control (QC) of many liquid and semi-solid materials.

Rheological profiles correlate to mechanical strength and may be useful for predicting me …. CA adhesives are the strongest and most homogenous group in terms of mechanical strength. Hydrogels (FG, AB) are heterogeneous, with lower mechanical strength than CA. FG are mechanically the weakest adhesives.

Compression tests revealed that these semi-IPNs were robust materials with compressive modulus between 13.3 and 90.5kPa, the addition of Salecan increased the fracture strain from 71.1% to 88.8%. Rheological measurements play an essential role in quality control (QC) of many liquid and semi-solid materials. Two Point Tests It is well established that the flow properties of fresh concrete at low shear rates approximate the Bingham model, expressed as follows: 2020-11-01 · More CH is an indication of the greater degree of hydration at higher curing temperatures which leads to enhancement of the rheological properties of the mixture due to the two following processes: i) the produced hydration products (e.g., CH, C–S–H, ettringite) fill up the voids, and also increase the solid volume fraction in the CPB system and ii) the consumption of water in the cement hydration process results in the reduced thickness of the adsorbed water film that Saliva is a complex biological fluid that cannot be effectively studied by conventional methods such as theFerranti-Shirley Viscometer.

Like other microbial polysaccharides, Salecan has fascinating biological properties including antioxidation and nontoxicity, which are typically needed in food and pharmaceutical industries. 22–24 Additionally, Salecan contains plenty of hydroxyl functional groups located on its backbone, and consequently making it convenient to be chemically

In this paper, a series of pH-sensitive hydrogels dynamic rheological properties of the pastes. An outline of the parameters which may be obtained by cone & plate or parallel plate rheometry is provided in Fig. 2. The present work provides a brief overview of the use of cone & plate and parallel plate rheometry for assessing the rheological properties of pastes used for screen printing. In this work, the rheological and nonisothermal crystallization properties of ABS/PA6-compatibilized blends prepared by reactive extrusion were investigated. The uniform distribution of submicron-sized ABS droplets resulted in dilatant fluid behavior and a transition to elastic behavior from viscous behavior in the low-frequency region.

They reported that the molar mass and the polymer concentration are the governing parameters, whereas the degree of substitution (DS) has only a little influence affecting primarily the solubility.

Moreover, enhancement in the rheological properties and 13.3–22.4% additional oil recovery demonstrate the possible applications of this natural surfactant–polymer system in EOR. Background: Adding lidocaine to hyaluronic acid (HA)-based gels appeared to modify their rheological properties, in the view of the first author. Objective: This paper sought to compare the rheological properties of three CE-marked and FDA-approved gels, administered with and without lidocaine, along with two other newly FDA-approved gels.
