The relationship between microstructures and mechanical properties of a medium carbon V-N microalloyed steel used for N80 seamless oil-well tubes of hot rolling non-quenched/tempered (non-Q and T) was investigated.The results have shown that volume percentages of upper bainite,modified bainite and ferrite have a decis…
Polypropylene foam was prepared with uniform design using high melt strength polypropylene as raw resin.The effects of formulation and process conditions on the cell size and apparent density of polypropylene foam were investigated.The relationships between the cell size,apparent density of polypropylene foam and para…
The oxygen storage materials LnxZr1-xO2(Ln=Ce,Pr,Tb) were synthesized using ultrasound-assisted osmosis-diffusion chemical method.Light-off technique was employed to explore the ignition properties of LnxZr1-xO2.The results indicate that the light-off properties of LnxZr1-xO2(Ln=Pr,Tb)(x=0.6,0.8) for CO or HC are supe…
According to the characteristics of laminated veneer lumber with uniform structure,high strength,good stability,cost-effective etc,it carried out a beneficial exploration and practice of the furniture modeling and structure design,and opened up a new direction for the development of LVL furniture.
This paper makes the research?and?analysis on SIEMENS model control structure and process data of TISCO’s Hot Strip Mill, puts forward the control method for neural network classified modeling in aspect of the development of high-speed steel roll for adapting to the rolling of high chrome nickel roll and high-speed st…
The situations of waste garments recycle and reuse in USA,Japan,UK,etc.were introduced briefly.The situation of waste garments in China and its handling were mainly analyzed,and the main business markets of waste garments in China were described.At the meantime,the recycling of waste garments in China was introduced,t…
A kind of biomass biodegradable foaming material which was made of plant fiber(straw fiber) and starch via foam molding process has been researched.Growth mechanism of bubble hole of this material was researched,too.Microscopic structure of four different kinds of materials which has different content of plant fiber,s…
The domestic and foreign research situation of variant structure wing and skin structure at present were first introduced.A type of Ripple Composite Material Skin structure was proposed to meet requirements of variant wing skin in the aspects of continuous smooth and large deformation.Necessary calculation expressions…
The advantages and disadvantages of the waterborne wood coatings in the application were analyzed and the water-borne polyurethane wood paint open colorful transparent painting process was explored,at the same time the hardness,wear resistance,resistance to dry hot properties,adhesion,impact resistance,resistance to l…
Nanobiotechnology is an important research topic in the field of analysis and detection.Functional nanoparticles are used widely for its unique optical properties,high surface area and size-dependent properties.Its basic characters,labeling approach and application in analysis are reviewed.
The research developments in antural storage hardening and the prohibiting methods for storage hardening were sumerised.
Objective To investigate the effect of different curing time and temperature on the hardness of composite resin.Methods Specimens were fabricated from nanofilled composite resins Z350 and stored at three different temperature(10℃,25℃,40℃).Then they were cured with LED light curing for 20 s or 40 s.The microhardness of…
Core-shell polymer was prepared using diolefin,styrene and methyl methacrylate as monomers by means of seed emulsion polymerization.The internal core of the product was rubber phase of crosslinked structure,and the external shell was methyl methacrylate.This paper studied the effect of the phase composition to the lat…
To establish expiration time and suitable package and transport conditions for compound peroxymonosulphate powder,the changes of sodium chloride and available chlorine were separately determined by potentiometric titration and iodometric method.The stability of the samples was tested by stress test,accelerating experi…
The welding tests on Gay cast-iron were made with four kinds of electrode by cold arc welding(Z208 Z248 Z308 Z116),metallographic microstructure,the width and microhardness of the partial fusion were compared in welding metallurgy.The results show that the welded joint by Z208 and Z248 is same with base metal,the weld…
