The effect of magnetic filed on carburizing behavior of pure iron was investigated. The results show that the magnetic filed can accelerate the carburizing process when the magnetic filed direction is perpendicular to the carburized surface,and this effect increases with the enhancement of magnetic filed intensity. Th…
Alkaline slag from a soda ash factory was used to prepare rubber filler.This paper described the relevant experiment which focused on rubber engineering test and the filler performance testing.The findings of the experimental study indicated that compared with the common filler and the super-fine calcium carbonates,th…
For the detection problem of such axial-oriented defects as narrow crack,weld,mechanical damage and corrosion pit,a circumferential excitation inspection method was proposed.The 2D finite element(FE) model of circumferential magnetizer in static state was established by analyzing the principle of circumferential magne…
By using embrittlement of titanium hydride,ultrafine titanium hydride powder can be prepared by high energy ball milling at room temperature.The influence of different milling condition on powder size and powder morphology has been studied,and the powders obtained in different milling condition are analyzed by Scannin…
Ethylene tetrafluoroethylene (ETFE) coating was prepared by flame sprayed. The processes of non-isothermal crystallization and the melt behavior of ETFE coating were investigated by differential scanning calorimeter (DSC). Fourier transform infrared spectroscopy (FT-IR) was used to characterize polymer degradation. Th…
The processes of electron beam surface modification on CVC8 aluminum surface by electron beam surface technique were studied to improve the experimental study of aluminium surface hardness and resistance.The microstructures and metallographic structures of layers were analyzed by using optical microscope,SEM and EDS r…
The microstructure and friction/wear properties of TiB2-TiN composite films in SiC/TiB2-TiN double layer films(SiC film as interlayer) deposited on Ti6Al4V alloy substrate using magnetron sputtering at room temperature were investigated. The results showed that the TiB2-TiN composite films exhibited the micro-structur…
This article describes the problems of the new austenite heat-resistant steel(HR3C) welding in the last stage reheater in Guangdong Huizhou Pinghai Power Plant and the solution by strict controlling the temperature between layers,the energy of welding wire and the root of argon protection;It finally resolve the proble…
In this paper,the relationship between compositions and properties of chlorinated poly(vinyl chloride)/acrylonitrile-butadiene-styrene copolymer/chlorinated polyethylene(CPVC/ABS/CPE) ternary blends was studied.The torque of CPVC/ABS/CPE decreased and thus the plasticizing time was reduced significantly with increasin…
Polymer dispersed liquid crystals (PDLC) is an excellent display material which combines the properties of liquid crystal and polymer. The research development of phase separation by thermal process (TIPS),phase separation by solvent evaporation (SIPS),and phase separation by polymerization (PIPS) was reviewed in this…
The influent factors of the contact prickle sensation on the general fabrics were elaborated,and the influences on the contact prickle sensation from the material,the weave construction and the production process of the clothing trademark were analyzed.
The yellow cocoon gene C is a key gene related for selective carotenoid transport for cocoon coloration of Bombyx mori.In this paper,expression differences of the two candidate genes,Cameo1 and Cameo2,were analyzed by reverse transcription-polymerase chain reaction (RT-PCR) in tissues and organs of the 4th and 5th ins…
The air cushion dryer is a thermal equipment to drying the pulp sheet,it used for removing the moisture which is difficult or impossible to dewater by press or other mechanical method.In a traditional paper and cardboard making process,the dryer cylinders group is used to further increase the paper dryness,but the lar…
A kind of flame retarded polypylene(FRPP) was prepared by melt extrusion. The nonisothermal crystallization properties of this new FRPP were tested by X-ray diffraction(XRD) and differential scanning calorimetry(DSC) methods. The results show that, adding intumescent flame-retarded(IFR) to PP can induce the proportion…
The magnetic hysteresis loops of Nd2Fe14B/α-Fe exchange-coupling multilayers are simulated by micromagnetic theory, and the relation between remanence, coercivity, energy products and soft magnetic thickness are studied. The results show that the hysteresis loops is rectangle and the multilayers are in complete exchan…
The surface of nano-calcium carbonate was modified by rare earth coupling agent WOT,the nano-calcium carbonate/SBR composite was prepared by mechanical blending method,and the properties of the composite were investigated.The results showed that,compared to silane coupling agent KH-560,rare earth coupling agent WOT pr…
In order to improve the dyeing property of the UV-absorbers on PET fabrics,some ester compounds are added into the dyeing baths with benzotriazole UV-absorbers together.Through the detection of the uptake of UV-absorbers onto polyester with DMF extraction method,the effect of n-amyl Acetate in dyeing PET fabrics is st…
In order to find out genes related to special characters of the Black-Bone Silky Fowl,differential display PCR was used for screening differential expressed genes between liver organs of the Silkies and the AA broilers,and bioinformatics analysis were carried out to identify ESTs differential expressed.There were tota…
Star-branched poly(e-caprolactone) (PCL) including hexa-armed star-shaped PCL (HPCL),dendritic PCL (DPCL),and linear PCL (LPCL) were spin-coated onto mica substrates at room temperature.The effect of molecular structure on the wetting-dewetting behavior of ultrathin film (about 15 nm) was investigated with atomic forc…
