1 买方市场是赊销现象的主要社会经济原因我国从经济转型过程中,社会生产力迅速发展,许多商品从供不应求转变为供大于求。在供大于求的现实情况下,竞争的压力往往迫使许多企业会采用各种促销手段,向买方提供优惠的交易条件,以求开拓市场,增加销售收入。赊销就是行之有效的促销手段。 相似文献

Influence of rubber on the curing kinetics of DGEBA epoxy and the effect on the morphology and hardness of the composites 总被引:1,自引:0,他引:1

The influence of the end groups of two liquid rubbers on curing kinetics, morphology, and hardness behavior of diglycidyl ether of bisphenol-A based epoxy resin (DGEBA) has been studied. The rubbers are silyl-dihydroxy terminated (PDMS-co-DPS-OH) and silyl-diglycidyl ether terminated (PDMS-DGE). Crosslinking reactions, investigated by shear rheometry, ranged 90–110 °C, using a constant concentration (5 phr) of liquid rubbers and 1,2-Diamino cyclohexane (1,2-DCH) as hardener agent. The gel time, t gel, of the neat epoxy significantly decreased when adding the elastomers, more so for the silyl-dihydroxy terminated elastomer; at 110 °C the reaction was nearly complete before rheological test started. The results suggest that the elastomers induced a catalytic effect on the curing reaction. Scanning electron microscopy revealed phase separation of the elastomer during the curing reaction with rubber domains about 5 μm size. However, the DGEBA/dihydroxy terminated elastomer composite cured at 110 °C exhibited a homogenous morphology, that is, the rapid reaction time would not allow for phase separation. Water contact angle tests evidenced either more hydrophilic (silyl-diglycidyl ether terminated rubber) or more hydrophobic (silyl-dihydroxy terminated rubber) behavior than the neat epoxy. The latter effect is attributed to the presence of aromatic rings in the backbone structure of PDMS-co-DPS-OH. Microindentation measurements show that the elastomers significantly reduced the hardness of the epoxy resin, the DGEBA/ether terminated composite exhibiting the lowest hardness values. Moreover, hardness increased as reaction temperature did, correlating with a reduction of microdomains size thus enabling the tuning of mechanical properties with reaction temperature. 相似文献

以硝酸锌和氢氧化钠为主要原料,研究了120℃和180℃水热条件下,OH^-与Zn^2+物质的量比为8时,不同添加剂D-山梨醇、十六烷基三甲基溴化铵、十二烷基三甲基溴化铵对所得氧化锌形貌的影响。通过扫描电镜(SEM)观察,所有产品都表现为由棒状氧化锌组成的向外辐射的球状体。120℃时,所得氧化锌棒的直径大小较为均一,其中不加添加剂和添加D-山梨醇时所得捧状氧化锌末端为锥形,添加十二烷基三甲基溴化铵的氧化锌末端为针形,而添加十六烷基三甲基溴化铵的氧化锌长径比更大,直径也更为细小;180℃时,只有添加十六烷基三甲基溴化铵所得氧化锌较为均一,其它3种情况下所得氧化锌都表现为大小不等的球体。 相似文献

Conclusions An increase to 4.5–5.5% in the concentration of anion vacancies in the lattice facilitates the transport processes in solid solutions. With a significant concentration of anion vacancies this process becomes difficult, as is indicated by the increase in the activation energy of conductivity.The stabilization of ZrO2 by oxides with a larger cation radius leads to a reduction in the level of conductivity of the solid solutions.The addition to the ZrO2 lattice of cations of stabilizing oxides with a charge close to that of Zr4+ facilitates the transport process of the oxygen ions.It is shown that, in principle, it is possible to predict the level of conductivity of solid solutions based on ZrO2 at 1200–1400°C.The use of a combined additive consisting of a mixture of rare-earth oxides to stabilize ZrO2 makes it possible to obtain solid electrolytes close in their electrophysical properties to the ZrO2-Sc2O3 electrolytes.Translated from Ogneupory, No. 4, pp. 15–18, April, 1985. 相似文献

This study explores the photoelasticimetry as a means to investigate factors affecting the residual stresses, particularly the thermal stresses, in polymethyl methacrylate (PMMA). The aim was to study the effect of quenching temperature in three different media: air, water, and ethylene glycol, on the impact strength and thermal properties of PMMA. These temperatures varied from a fixed value of 120°C to various values below Tg and the fields of distribution of cooling stresses have been obtained using a charge-coupled device (CCD) camera. It was observed that the quenching in water at 20°C gives rise to an important density of tensile stresses. However, in the ethylene glycol at 110°C this density has a tendency to disappear. An approximate evaluation of these stresses in a point near the specimen center has been assessed, and it was found that the distribution profile of the fields of tensile stresses was much closer to a parabolic form. Notched Izod impact strength and heat deflection temperature (HDT) were measured, and were found to be particularly sensitive to thermal stresses. 相似文献
