Microcapsule and the principle of micro capsulation technology were introduced in this paper. And the paper still introduced the application of micro capsulation technology in textiles and gave its future prospect.
An overview for the development background of the water-based emulsion in cold-rolled aluminum process is presented,and extensively studies on cold rolling lubrication at home and abroad,effects on the surface quality of cold rolled aluminum,such as roller and the surface roughness of roller and cold-rolled aluminum s…
It establishes the finite element analysis mode of high speed power-operated chuck with ANSYS,analyzes the strength and stiffness of clamping transmission in the largest clamping force,simulates the friction coefficient at major surfaces,discusses the length of claws' outgrowth,claws' clamping position influence to st…
Low modulus potassium silicate solution and silica sol were adopted to prepare the high modulus potassium silicate solution with good stability.The influences of temperature,various silane coupling agent and agitation speed on the preparation of high modulus potassium silicate were discussed.The performance of the dev…
The reaction pathway for reforming coke oven gas(COG)in an oxygen permeation membrane was analyzed.Through the reforming experiments of H2+N2 ,CH4+N2,CO+N2,H2+CH4+N2 mixtures,with or without a catalyst and the catalyst bed,the reaction scheme is proposed:H2 in COG is absorbed and dissociates on Ni particle on catalyst…
[Objective]The research aimed to study the feasibility of laboratory culture of O.marina Dujardin,to lay foundation for study of its physiological and ecological characteristics and formation mechanism of red tide.[Method] Food algae were Chlorella pyrenoidosa,Isochrysis zhangjiangensis,Platymonas subcordiformis and P…
For the shortcomings of difficult modeling and large simulation calculation in VARI process molding simulation of large size or complex shapes sandwich structure composites with traditional refined modeling method,this paper proposes a simple and convenient equivalent modeling method in which a VARI process molding si…
Die casting process of magnesium alloy steering wheel frame was simulated by AnyCasting software.The results show that the good castings can be obtained by adjusting initial temperature and pouring temperature of the lower and upper die,setting cooling pipe system.The optimized process parameters are as follows: filli…
Crude extracts and fractions were separated from ethanol extracts from Ishige okamurae Yendo;and Corallina officinalis L.were tested for their efficacy against three kinds of bacteria and two kinds of fungi through the circle agar disc diffusion method.The results showed that extracts of Ishige okamurae Yendo.and Cora…
The difference between multistage pulse high energy gas fracturing and single pulse high energy gas fracturing was presented.In certain degree,the deficiency of the single pulse gas fracturing was improved,the key lay in the uniqueness of the fracturing mechanism which is to depend on interaction of high energy gases…
PELE is a projectile based on a novel kind of damage mechanism,which produces obvious lateral efficiency on the target and damages for objects behind the target.In order to analyze the influence of impact angle on PELE,numerical simulations at different impact angle were carried out.The results indicate that the impac…
To apply the CA4DC2-10E4 electronic-controlled common-rail engine to the Dandong ShuGuang DaChaishen pickup,a roller emission test is carried out for the study on the effects of diesel oxidation catalyst,EGR cooler and optimization of calibration map on vehicle exhaust emissions and performance.The results show that:…
In this paper,multiple insulation testing techniques of GIS equipment are expounded and synthetically evaluated.The method of the AC voltage withstanding test and PD(partial discharge) detection are conducted,and lightning shock test can be used in detecting all defects of the GIS equipments.Finally,the future of the…
