Crystallization enhances the melt point or surface crystallinity of polymers to facilitate further processing. We can help influence polymer properties to avoid sticky material and ensure you have freeflowing pellets. Ancos utilizes a proprietary process for crystallizing polymers that are typically quite difficult to handle.
The degree of crystallinity has a significant influence on hardness, density, transparency and diffusion. However, the properties are not determined only by the degree of crystallinity, but also by the size of the structural units or the molecular orientation.
influence of the volumetric grinding wheel compos ition and the resulting grinding wheel topography on the thermomechanical stress collective acting on the workpiece external zone. Thus, it is not possible to make a quantitative statement about the influence of the volumetric grinding wheel

Corrosion of Additively Manufactured Alloys: A Review The Slow Strain Rate Stress Corrosion Cracking Test—A 50 Year Retrospective Metal Release and Corrosion Resistance of Different Stainless Steel Grades in Simulated Food Contact Corrosion of Painted Metals—A Review Adsorption Behavior of Organic Corrosion Inhibitors on Metal Surfaces—Some New Insights from Molecular Simulations
In recent years, comilling of active pharmaceutical ingredients (APIs) with excipients is being investigated as a promising technique to improve physicochemical properties such as solubility[1], bioavailability[2], aerosolization[3] and physical stability[4] of various APIs.
CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Minerals of the tobermorite group with double [Al3++Na+] substitutions were synthesized using both, nonground raw mineral mixtures and mixtures ground in a colloidal mill. The synthesis of calcium silicate hydrate is more effective when dry primary mixtures ground in a colloidal mill are taken, because compositions ...
as form, surface type and phosphate groups influence the starch's properties and uses (Smith, 2001). Characteristics of starch granules: morphology, size, composition and crystallinity Starch granules have microscopic sizes with diameters ranging from to 200 µm, .
The aim of this study was to produce niflumic acid nanoparticles without using an organic solvent, in order to achieve an increased rate of dissolution of the final products. Cogrinding with excipients was used to decrease the particle size. Poloxamer 188 (P) and mannitol (M) applied as cogrinding materials stabilized the system, preventing aggregation of the nanocrystals.
PINKAS, Jiří, Edita GARSKAITE, Aldona BEGANSKIENE, Giedre NENARTAVICIENE a Aivaras KAREIVA. Influence of annealing temperature on the phase purity, crystallinity and optical properties of Y3Sc2Ga3O12 prepared by different methods.
For the untreated groups, the degree of crystallinity of the welding interfaces was higher than that of the wood dowel. For the treated groups, the degrees of crystallinity for the welding times of 5 s and 7 s were lower than that of the wood dowel. By extending the welding time, the degree of crystallinity decreased.
Sep 10, 2013· Crystals and Crystallinity in Polymers examines all the possible types of structural disorder generally present in polymer crystals and describes the influence of each kind of disorder on Xray and electron diffraction patterns. Its comprehensive, expert coverage makes it possible for readers to learn and apply the fundamentals of polymer ...
PSA. The XRD analysis showed that the crystallinity degree of nanocellulose was higher than cellulose in the amount of %. 1. Introduction Cellulose is one of the most abundant, natural, renewable and biodegradable polymers [1, 2]. Cellulose can be found in wood, cotton, rice straw. s, and sugarcane bagasse [25]. Sugarcane bagasse is a ...
no data are available on the influence of SDS and CTAB surfactants addition on the crystallinity of EN deposits on mild steel specimen. The objective of this present study is to promote the formation of the amorphous phase in the EN ... then finished by grinding followed by .
showed that better crystallinity was observed in multistage sintered sample. The enhancement of crystallinity in multistage sintered sample is due to intermediate grinding process which provides more homogenous size, better diffusion and grain ... LaSrMnO system are dependent on sintering effect which could influence magnetic and ...

Purity : ... from atmospheric oxygen, heat, light and humidity. If material is poorly water soluble increases dissolution rate by grinding. Grinding reduces coarse ...
Poly(llactic acid), PLLA, in amorphous and semicrystalline forms were studied by DSC, in order to investigate both molecular dynamics and structural relaxation features, and to understand the influence of the crystalline confinement on the segmental mobility of the intraspherulitic amorphous phase. Experimental data were generated after submitting the materials to different thermal ...

Poly(2oxazoline)s are suitable materials to study structure–property relationships as their preparation by a living cationic ringopening polymerization procedure and the relatively facile monomer synthesis allow accurate control over the molecular structure. In this contribution, the number of carbon atoms
GRINDING The large amounts of heat generated by grinding, together with the low heat conductance of nylon, usually dictate that liberal amounts of coolant he used in most grinding operations. Thrufeed centerless grinding of long, flexible parts of nylon can be easily accomplished, and tolerances as close as .0005" are possible.
