The character and principle of curing of phenolic urethane resin no bake sand process was introduced. The characters of pinhole defects on the surface of casting which was produced with phenolic urethane resin sand were analyzed. The partial excess of polyisocyanate is the primary cause of dispersive pinhole defects. The pinhole defects can be solved fundamentally by improving the uniformity of sand mixing and making sure part I and II react at certain ratio. The field test shows that improving the performance of the mixer, decreasing the viscosity of resin and prolonging the mixing time can all improve the uniformity of sand mixing. After improving the uniformity of sand mixing, the pinhole defects of the casting were cancelled, quality remains excellent.

To improve the thermal and mechanical properties of isotactic polypropylene (iPP), iPP/Kevlar fiber (KF)/polyamide 6 (PA6) composites were prepared via the melt-extrusion method on twin-screw extruder. Kevlar fiber was modified with caprolactam using toluenediisocyanate (TDI) as bridge. The microstructure of modified KF was successfully characterized by Fourier transform infrared (FT-IR), X-ray photoelectron spectrometer (XPS) and scanning electron microscopy (SEM), the results showed that KF was bonded with caprolactam and became coarser. Then the modified KF was introduced into iPP, the composites have better mechanical and thermal properties, implying that modification of KF was helpful to improve the interfacial interaction of iPP/KF/PA6 composites. Besides, the crystallization curves indicated that crystallization behavior of PA6 in the composites was homogeneous and fractional. Furthermore, compatibilizer content played an important role in the mechanical and thermal properties of composites. © 2011.

The high work intensity, the low production efficiency, the poor coating surface quality and some other problems existed in brush coating technology during traditional resin sand casting production. Flow coating technology can decrease the work intensity and improve the working environmental, moreover, meet the requirements of the resin sand casting continuous production. The casting size accuracy and surface quality were improved. The technology performance and index of flow coating mixture were introduced in the factory. The common problems and solution measures in flow coating process were summarized in this paper.

The influences of hyperbranched polyethylenimine (hPEI), which possesses many reactive amino end-groups, on the blending properties of bisphenol-A polycarbonate (PC) and amorphous polyamide (aPA) were systematically investigated. Scanning electron microscopy (SEM) and differential scanning calorimetry (DSC) were used to observe the effect of hPEI on morphologies of PC and aPA phases in bulk blends. While the interfacial fracture toughness between planar PC and aPA layers with and without hPEI was studied by using augmented double cantilever beam (ADCB) method. Results show that the compatibility in PC/aPA blends can be significantly improved by adding a small amount of hPEI, mainly due to the interchange reactions between the polymers leading to the formation of block copolymers, cross-linked polymers and molecules with other constitutions. The augmented double cantilever beam experiments showed that the reactive process drastically reinforced the interfacial adhesion between planar layers of PC and aPA. However, degradation takes place during annealing at 180 °C, which was responsible for the production of small molar mass species of PC. © 2015, Chinese Chemical Society, Institute of Chemistry, Chinese Academy of Sciences and Springer-Verlag Berlin Heidelberg.
