Abstract Aiming at formulating reasonable curing process parameters of powder coating, solving the problems over-drying thin plate and impervious drying thick during combined workpieces with different thicknesses, analyzing optimal temperature range coating by differential scanning calorimetry (DSC), designing a three-factor four-level DOE test scheme within to time are necessary. Using Minitab...

The mechanical properties of polymer impregnated concrete containing polypropylene fiber were statistically and experimentally examined in this study. Taguchi L9 (33) was used variables for experiments selected as the ratio (0%, 1% 2%), cement dosage (300, 350 400 kg/m3) curing time (7, 14 28 days). After specimens cured at specified times, they dried 105 ±5 °C. Then, monomer to 24 hours under ...

Poly(ethylene-alt-maleic acid), PEMAc, is a linear polymer that, along with its isomer polyacrylic acid, has the highest carboxylic acid content of any polymer. The goal this work was to elucidate mechanisms that control amount PEMAc permanently fixed on pulp fibers after impregnation dry dilute solution followed by drying/heating (curing). Two which cellulose were discovered, chemical, and phy...

Novel types of main-chain, lyotropic liquid-crystalline polymer networks consisting of polyisocyanate chains were prepared by hydrosilation cross-linking. The characteristic liquid-crystalline band texture generated by shearing these networks in the swollen state was found to persist much longer than in the case of solutions of the same polymer in the un-cross-linked state, suggesting preservat...

In this study, calcined zeolite particles were used as internal curing agent to replace cement and quartz sand simultaneously in Ordinary Portland Cement(OPC) based Engineered Cementitious Composites(ECC) material. The influence of the zeolite-cement replacement on mechanical performance shrinkage materials experimentally investigated. ECC specimens with water-binder ratio 0.2 content 192 kg/m3...

Water tightness of a concrete cover layer is important, as it is typically used as a protective coating of the steel reinforcement. Water tightness can be impaired by crack formation or by permeability. A bacteria-based lactate-derived healing agent (HA) can be added to concrete to enhance the potential for restoration of water tightness. Bacterial conversion of the included carbon source resul...

The durability of adhesive joints is of special concern in structural applications and moisture has been identified as one of the major factors affecting joint durability. This is especially important in applications where joints are exposed to varying environmental conditions throughout their life. This paper presents a methodology to predict the stresses in adhesive joints under cyclic moistu...

Mulberries are a rich source of nutrients and bioactive compounds. Morus nigra, alba, rubra the most commonly studied types mulberry, they contain significant amounts protein, fibre, vitamins, polyphenols which help in curing diseases. With their higher nutritional composition compound also highly perishable nature due to water content for storage different drying techniques used as result get ...
