The alkaline proteases DHAP, which produced by Bacillus pumilus BA06, is capacity of hide dehairing. In order to get more insights into catalytic properties, and for improving the performance of DHAP in leather processing, 13 residues were selected for site-directed mutagenesis based on the homology modeling of DHAP a…
Nowadays,the flat thermal instrument is widely used in the test for thermal property of fabric.The structure of heating is like a flat pan whose way of heat transferring is different from that of a human body and whose thermal property can't be tested in an open environment.Based on the study of the requirements and c…
The biopesticide cyhalothrin was microencapsulated with chitosan and sodium lignosulfonate by a complex coacervation method.The optimized reaction conditions were identified,including mass ratio of core to shell,temperature,stirring speed and its properties were studied.
Titanium and titanium alloys are used more and more widely in national economics and defense industry currently.To improve the application characteristics,some surface treatments are adopted.Electrodeposition of metal is a common and convenient method.By electrodeposition of metal,the functionality,decorate properties…
In order to discuss the variation of the length and crimp properties of the cashmere fiber which is caused the geographical conditions and breed improvement of the different area,this article plates the cashmere fiber and respectively tests,compares and analyzes the performance of the length and curl of the normal cas…
This paper introduced alteration on mechanical strcture parts of the draw bath.The measure improved the fiber quality and reduced production costs.
On the Si/SiO_2 substrate,large area and continuous graphene films are prepared by chemical vapor deposition method,using nickel film by magnetron sputtering as catalyst.The layer numbers of graphene range from 1 to 15.By transferring these graphene films to glass and Si/SiO_2 substrates.The transmittance and sheet re…
The study on the balance and evaluation between advantage and disadvantage of chemical synthesis process of preparation for nanomaterials of molybdenum trioxides has been achieved in detail in this paper.Research conclusion has shown that union flow is the crucial factor in determining the structure and performance of…
Flaky graphite is one of the best floatability mineral in the nature.It was difficult in processing graphite to protect the flaky structure of flaky graphite.For a crystalloid graphite in Inner Mongolia,preconcentration technology had been used to protect flake graphite.The results showed that it can increase the grad…
With the phenomena of low electricity efficiency and general high temperature of plate resulted from large-scale scraper or much use of new anode plate as the starting point,the authors,through analysis of the behavior and reaction of anode mud in the electrolysis process,discovered the underlying causes of low electr…
Eight kinds of normal girdle fabrics were collected.Forty girdles were made with five different sizes according to the standard pattern.Clothing pressure and the elasticity of fabrics were measured and drawing the factors influenced clothing pressure including warp and weft once and 5th elastic recovery,weft breaking…
Static recrystallization behavior of hot-rolled ferrite stainless steel 410S was studied by means of recrystallization experiments with different temperature-time regimes.Results indicated that,in order to avoid re-emergence of martensite and speed up recrystallization,the optimal annealing temperature was 780~800 ℃ f…
Bifunctional-benzoxazine(B-BOZ)was modified by liquid carboxyl terminated butadiene-acrylonitrile rubber(CTBN),and the properties of the system with different mass ratio of CTBN to B-BOZ were studied. The results show that the viscosity of the modified resin is below 0.5 Pa·s under the condition of setting CTBN conten…
The wetting and spreading of Ni-56Si alloy on SiC ceramic were performed under different temperatures and atmospheres by the sessile drop technique. The microstructure and phase compositions of solidified sessile drop/SiC substrate interface and drop surface were analyzed by scanning electron microscopy and energy dis…
A d-f heterodinuclear complexes [Fe(phen)3]2[FeCe(tiron)3]·6H2O (tiron=C6H2O8S2) was isolated from the hydrothermal reaction of Ce(NO3)3·6H2O, Fe(NO3)3·9H2O, 1,10-phenanthroline and 4,5-dihydroxybenzene-1,3-disulfonate, and characterized by elemental analysis, IR, UV, TG and single-crystal X-ray diffraction analysis.…
Polypropylene(PP)/nano-TiO2 composites were prepared via melt mixing.The dispersion of nano-TiO2,spherulitic morphology,and nonisothermal crystallization behavior of PP were stu-died using transmission electron microscopy(TEM),polarized optical microscope(POM),differential scanning calorimetry(DSC),and wide angle X-ra…
The import torque axis was analyzed,and the possibility of using domestic materials of torque axis instead of the imported was researched.The comparison between two kinds of materials shows that the performance of the domestic torque axis is similar to that of the imported under tests for chemical composition,mechanic…
The 2-butene-1,4-diol chlorophosphate was synthesized by the 2-butene-1,4-diol and phosphorus oxychloride.Then,the 2-butene-1,4-diol chlorophosphate reacted with m-nitroaniline and got an new type phosphorus-nitrogen flame retardant 2-butene-1,4-diol chlorophosphate m-nitroaniline(BPN).The structures of BPN were confi…
Aiming at staining problems in conventional washing machines after printing,a new printing and washing machine LMH028-180 was launched with the mechanism of padding acid liquor first and then countercurrent rinsing.The new machine was equipped with high efficient steaming and washing unit,dynamic cycle filter unit,and…
Newly thiol-groups functionalized polyvinyl alcohol-gelatin composite microspheres adsorbers were successfully prepared by using raw materials of polyvinyl alcohol and gelatin,and cross-linking agent of chloromethylthiirane.The resulting microspheres adsorbents exhibit definite component,uniform size,large special are…
