The recent progress on the compatibility between polypropylene(PP)and intumescent flame retardant was reviewed.The compatibility could be improved by using charring agent,coup-ling agent,micro-encapsulation,grafting modification,latex blending,and so on.PP grafted with flame retardant monomers,synthesizing the PP comp…
This article uses the theory of the finite group,giving out the complete classification of the finite groups with the set of the number of the same order subgroups={1,p+1}.
The reason of the seriously damaged carbon fiber and no obvious strengthening-toughening effect for Cf/TiC-TiB2 ceramic matrix composites prepared by the SHS/PHIP technology was analyzed and researched.The results show that reaction temperature is too high in the SHS reaction process of B4C+3Ti+Cf system,chemical reac…
Tungsten coated on the stainless steels,such as EURFOR,F82H,316L,are promising plasma facing components for future fusion reactors.In order to avoid the crack failure due to thermal expansion mismatch of the W coating and the steel substrate,the functionally graded materials(FGM) concept is adopted.The effect of the F…
Fibers with different hemicellulose contents were produced using various degree removal of hemicellulose to obtain large differences in cellulose and hemicellulose proportions at a similar lignin content. Solid state cross polarisation magic angle spinning carbon-13 nuclear magnetic resonance( CP/MAS 13C-NMR) and atom…
The conductivity(ρ)and shielding effectiveness(SE)of eectromagnetic interference(EMI)shielding coating materials of acrylic resin matrix,alkyd paint and phenolic paint using polyaniline adoped by camphor sulfonic acid(PAn-CSA)and nickle powders as conductive fillers,KH-550 as coupling agent were measured and analyzed.…
This paper was focused on the property variations of the Ag-Ce alloy with different Ce contents.The relation of the hardness,yield strength with Ce content was systematically researched,and the hardness variations of the Ag-Ce alloy with Ce content and temperature were revealed.The variations of yield strength and the…
Aimed at studying the catalytic activity of the mesoporous catalysts,this paper introduces the preparation of mesoporous Cu/SBA - 16 catalysts with 3-D pore structure by modified impregnation method with pH adjustment and the investigation into the effects of pH and Cu loading on catalytic activity of phenol hydroxyla…
Microcapsules with a urea-formaldehyde resin wall were prepared for sethoxydim herbicide by in-situ polymerization method.The influencing factors,such as pH value of pre-polymerization reaction medium,reaction temperature,catalyst,the end pH value,on the formation of sethoxydim herbicide microcapsules,the structure an…
This paper tested the water absorption of cocoon shell under the environment of different vacuum,different water temperatures and different osmotic agents,and through the analysis,we obtained that the key factor of permeation of the cocoon shell was vacuum.The water temperature and osmotic agent could also improve the…
ZrO2 color separation grating(CSG)was devised by photosensitive sol-gel binary optics method.The grating's refractive index was measured with ellipsometer,and its structure parameters were acquired by white light interferometer.These values were input to a computation program to calculate the grating's theoretical dif…
Dynamic compressive properties of a 40 vol%SiCP/2024Al composite and its matrix 2024Al were studied at various strain rates using split Hopkinson pressure bar(SHPB).The flow stress of the composite and 2024Al is strain-rate insensitive above 1500 s-1,and the composite's yield strength is higher than that of 2024Al.Dif…
Taking acrylic acid(AA) and N′-hydroxysuccinimide as monomer,N′,N′-methylene-bis(acrylamide)(MBAA) as crosslinking agent,and ethanol solution as porosity preparation,a new copolymer carrier has been obtained by inverse suspension polymerization,a new copolymer carrier has been obtained by inverse suspension polymeriza…
The crystal structure of gypsum-based hydration product was changed by means of adding magnesium oxychloride admixture into the hemihydrate gypsum.The experiment results show that magnesium oxychloride admixture can significantly increase the physical and mechanical properties of gypsum base.The best adding proportion…
The N. flagelliforme cell was cultivated on three solid bed-materials with different wettability,which were sand,PA6 and glass residue. Added water,BG11 and BG110,then the changes of biomass of N. flagelliforme and extracellular polysaccharide were investigated to design the suitable medium. The results indicated that…
Pt/SrRuO3(SRO)/BiFeO3(BFO)/SRO/SrTiO3 heterostructure had been fabricated on SrTiO3(001) substrate,in which SRO and BFO thin films were deposited by RF magnetron sputtering and pulsed laser deposition,respectively.The effect of deposition temperature on the structural and properties of BFO thin film were investigated…
The advantages of water borne inorganic zinc rich coatings and the existing problems was described.And point out through the modification of the base materials,and pigment and fillers,along with the adding of various additives to improve the comprehensive performance of water borne inorganic zinc rich coatings.
The starch graft initiator type was introduced in this paper.The research and application of acrylonitrile,acrylic acid and acrylic ester or acryl amide three series of absorbent resin were expatiated.The application of this resin in the fields of personal care product,medication,agriculture and gardens were also intr…
The absorption behaviors of VO-OEP were researched using acid modified and supported Ni kaolinite as absorbents in cyclohexane. The absorption mechanism was investigated with thermodynamics. The results show that the absorption process follows the law of Langmuir,which indicates that the monolayer VO-OEP is absorbed o…
Monodisperse calcite microparticles were fabricated by using biomacromolecule-gelatin as template.Spheric and flower-like calcite spherules were obtained.The SEM results indicate that both the temperature and the added SDS effectively influence the shape of the obtained calcite particles.The pure phase of calcite of a…
