Activated carbon supported zinc ferrite precursor was obtained by ultrasound assisted co-precipitated method.Characterization of desulfurizer was carried out using powder X-ray diffraction,BET methods and mechanical strength.The process of desulfurization was examined under the simulated coal gasification gas in fixed…
In order to reveal how two main film forming elements,C and Cr,exist and distribute in amorphous carbon film,Cr-doped carbon film with gradient transition layer was prepared by unbalanced magnetron sputter ion plating deposition technique. High resolution transmission electron microscopy (HRTEM) was utilized to charac…
CCD imaging technique,laser flash method and differential scanning calorimeter were utilized to measure the thermal expansion,thermal diffusivity and specific heat of polyimide(PI) films and carbon modified PI composite films(PI/C) at different temperatures.Influences of carbon and temperature on the thermophysical pr…
The causes and controlling measures of knitted products were mainly discussed.It pointed out that the hidden stripes are mainly generated due to equipment precision,course mark are mainly generated due to knitting operation and yarn quality.Some controlling measures were presented.
A series of Ce1-xFexO2 mixed oxides with different Ce/Fe molar ratios were prepared via hydrothermal method. The effect of Fe content on structure and porperty of the prepared catalysts were characterized by powder X-ray diffraction (XRD),BET specific surface area,Raman spectroscopy,and H2 temperature-programmed reduc…
In this paper,through high quality wool blended yarn with aramid and other special type of fibers,putting forward that during the production process,aramid fibers become from loose ones to tops and blend with wool tops and the key points of formation and quality control on every key working procedure and notes in the…
The BuGong tea saponin 2#,a novel environmentally friendly and high efficient auxiliary was applied to cotton satin fabric pretreatment in one-step.The orthogonal experiment results showed that,the optimal application process was BuGong tea saponin 2# 40 g/L,H2O2 10 g/L,NaOH 10 g/L,steaming time 45 min.The treated fab…
Nano-scale powders of C6H10CaO6 have been prepared by a chemical method.The relation between ζ potential and dispersity of calcium lactate during the process of preparation has been studied.The isoelectric point of calcium lactate nanopowders is determined to be 6.5.By adjusting pHs of washing liquid and reaction syst…
Fracture analysis of bend TP304H tube on pendant-heater operated on super-heater for 62000 hours in a 1021 t/h boiler was carried out by means of examinations such as macro- morphology of crack,mechanical property and metallographic of tube steel.The results showed that the corrosion cracking resistance of the TP304H…
In the modern shipbuilding of integration of hull,outfitting and painting,the development of ship regional coating technology is one of the essential foundation and the results of modern shipbuilding technology development.Through the analysis of the recent operation of ship regional coating technology,the key problem…
A nano-modified chitosan was prepared by oxidation methodology and nanotechnology.Medical antibacterial latex was prepared using the nano-modified chitosan as antibacterial agent and natural latex by mechanical blending method.The microstructure of the medical antibacterial latex was studied by scanning electron micro…
Using biochemical process to treat mixed wastewater containing waste acid and wastewater from CuPc production,the treatment cost was high and the effect was poor.Three schemes: waste acid reclaim,pressure filtration reuse of phthalocyanine blue rinsing water and resource recovery of mixed wastewater were pointed out a…
Objective:To prepare and research Palmatine pellets.Methods:According to the orthogonal experimental design,and selected the best palmatine pellets preparation,and optimize the coating process pellets,and enhance the stability of preparations.Results:The optimum conditions were screened out as A3B3C3,which was distill…
With the rapid development of urbanization,city household trash bring more and more severe danger to environment and have been important pollution sources impacting on city inhabitation environment.Therefore it is very critical on how to rational collect and disposal city household garbage.Though being taken as repres…
Polyaspartic Acid(PASP) is synthesized with Maleic anhydride and ammonium salt as raw materials through solid phase reaction.The results show that the performance of scale inhibiting to calcium carbonate is at its best when the average molecular weight is about 4 000,and this kind of PASP can be well used in high temp…
The stress corrosion cracking(SCC) behaviorof X80 pipeline steels joint in Ku'erle soil simulated solution was studied using otentiodynamic polarization technique and slow strain rate testing.Fracture surfaces were observed by SEM observation under different applied potential condition.The results show that the polari…
B-Al-EU-1 zeolite was synthesized in HMBr2-Na2O-Al2O3-SiO2-H3BO3-H2O system by solid phase transformation with the crystallization time of 48 h,which was greatly shorter than the crystallization time of 168 h in preparation of the sample by hydrothermal method.The prepared B-Al-EU-1 samples were characterized by XRD,F…
