With excellent bonding performance, formaldehyde-based adhesives have been widely used for the production of woody materials. However, these could potentially cause harm to human health and environment. Herein, we report an eco-friendly soy-based adhesive (SBA) by constructing a pressure-responsive crosslinker system with core–shell structure. Isophorone diisocyanate (IPDI) was encapsulated in microcapsules as core, shell mainly consisting polyurethane hinder crosslinking reaction between...
Steer-by-wire (SBW) is a crucial chassis electronic control system. Accurate and rapid wheel angle key to enhancing system performance. This paper first establishes dynamics model of the steering actuator. Then, co-simulation vehicle with CarSim Simulink built, feasibility SBW experimentally verified. Based on this, front compensation difference tracking strategy proposed using method. compensates for between actual ideal angles achieve desired progressively. A dual-layer controller designed...
Pb0.5Sr0.5TiO3 (PST) films having a pure polycrystalline perovskite phase and well-grown grains were prepared by chemical solution deposition method. Their optical response from 1.1 to 5.0 eV was investigated transmittance spectroscopy, the complex dielectric functions parameters evaluated in terms of Tauc–Lorentz Cauchy models. The direct band energy interband transition valence conduction bands determined be 4.09 eV. Below this fundamental absorption region, range 3–4 behaves as...
ABSTRACT In this article, Polynorbornene (PNB)/Zinc dimethacrylate (ZDMA)/Dicumyl peroxide (DCP) composites can form dual‐crosslinking networks, which contain an ionic crosslinking network, and a part of the C─C covalent network. DCP was used to initiate polymerization ZDMA bonds. With increase ZDMA, total crosslink density ( V r ) 2 increased. consumed in polymerization, made PNB reduce networks. Leading 1 decreased. Compared with networks stored more energy when deformed, provided better...
Purpose The purpose of this study is to prepare a new self-emulsified waterborne epoxy hardener which can emulsify the liquid resin in aqueous media without addition acid neutralizers. Design/methodology/approach Two synthetic steps were adopted novel amine-epoxy adduct type composition based on reaction commercially available polyetheramine, bisphenol A and triethylene tetramine. different factors affecting synthesis explored by emulsifying curing properties. process products analyzed...
Preload optimization is very important for ultrasonic motors’ design and application. In this paper, a novel method traveling-wave rotary motor proposed. Firstly, based on linear regression the analytic hierarchy process (AHP), mapping between drive characteristics, mechanical speed stability, preload of traveling-wave-type was established. Then, characteristic curves stalling torque, no-load speed, maximum efficiency, stability with change were measured new test platform. Finally, three...
The use of furfural-acetone slurry as active diluents Bisphenol-A epoxy resin (DGEBA) groutings has been studied by dynamic and non-isothermal DSC for the first time. Curing kinetics study was investigated differential scanning calorimetries at different heating rates. Activation enery (Ea) calculated based on Kissinger Ozawa Methods, results showed that Ea increased from 58.87 to 71.13KJ/mol after were added. matrix could cure completely theoretical curing temperature 365.8K time 139mins,...
In this research, carbon fiber (CF) was taken as reinforcing filler, nano calcium carbonate (CaCO3) toughener, maleic anhydride grafted polyethylene (PE-g-MAH) compatibilizer for high density (HDPE) modification. Through orthogonal test, the influence of different amount ingredient CF, CaCO3 and PE-g-MAH on mechanical properties HDPE composites researched. The optimal composition quaternary with good toughness strength obtained.
Abstract Self-heating methods are widely used in the thermal conductivity measurement of polymer fibers. In these methods, a thin metallic film is needed to be coated on fibers if electrical insulators. this paper, conductivities oriented polypropylene before and after gold coating were measured. The results shown that gold-coating process can reduce by about 50%. Therefore, self-heating not appropriate for measurements insulative polymers. This finding important research conductive...
