Wax deposition phenomenon changes the rheological behavior of waxy crude oil completely. In the current work, the rheological time-dependent and time-independent behaviors of waxy crude oil samples are studied and flow curve and compliance function are measured for the oil samples with various wax contents at different temperatures. A decrease in temperature and an increase in wax content lead ...

This manuscript describes the potential of a cutinase from the fungus Fusarium solani pisi for cotton wax degradation in order to design an efficient low temperature scouring process. The main characteristics, relevant to cotton wax removal with F. solani pisi cutinase are given. The additive effect of cutinase on pectinase was investigated and optimum incubation conditions were determined. Com...

The main objective of this research is to investigate the effect of dewaxing and burnout temperature on the quality of copper alloy casting produced by a low cost block mold that has been developed. In the molding process, two types of silica sand which contains 97.9% silica (SiO2) and 97.2% silica have been used as a refractory material with POP served as a binder. Several mold formulations co...

This paper reports the substitution of polyolefin backbone binder components with low melting temperature carnauba wax for powder injection moulding applications. The effect of various binder compositions of Al₂O₃ feedstock on thermal degradation parameters is investigated by thermogravimetric analysis. Within the experimental framework 29 original feedstock compositions were prepared and the s...

Natural ester-type gum bases, which are used worldwide as food additives, mainly consist of wax esters composed of long-chain fatty acids and long-chain fatty alcohols. There are many varieties of ester-type gum bases, and thus a useful method for their discrimination is needed in order to establish official specifications and manage their quality control. Herein is reported a rapid and simple ...

introduction: stored product pests are a major problem in the storage of agricultural products that cause damage from harvest until consumption. greater wax moth (galleria mellonella l.) is one of the most important pests of stored products and beehives. the most common method to control this pest in many countries is use of chemical compounds. however, these compounds have disadvantages such a...

One such method, Differential Scanning Calorimetry (DSC), detects WAT by measuring the difference in heat absorbed or released between a reference sample and the test sample at a given cooling or warming rate. The WAT is detected by a deviation of experimental data from the reference baseline and typically requires a significant amount of wax formation for sensible detection. Consequently, it m...
