蜂窝技术的发明和应用己有60多年的历史了,始于军品,后用于民品[1]。军品和民品都是运用蜜蜂窝状作芯,经过复合成材。军品是用铝合金作为原料,民品是用纸作为原料,其基木原理是一样的。二战之后,蜂窝夹层材料在发达我国应用发展很快,特别是荷兰、英国,技术装备的现代化水平很高,产品质量稳定,在航天、航空、建筑、包装、交通运输等很多领域已广泛应用[2],相应配套装配技术也很完善。 近年来,蜂窝纸箱的应用在我国也得到了快速的发展。在设备及产品的开发研制方面,均取得了显著的成就。全国包装改进办公室已将推广应用蜂窝纸箱作为我国改进工作的重点,并多次召开了蜂窝复合包装材料会议,大力支持在我国尽快推广应用[3]。在1998、1999和2000年,我国经贸委资源司综合利用与环保处、我国发展计划委员相继分别发布了重要公告,明确规定蜂窝纸箱作为我国重要技术予以重点发展[4]。 的一些和学者在这方面做了一些有意义的工作。例如: 王梅[5]通过静态少压缩实验对蜂窝纸箱的缓冲性能进行了研究。郭彦峰等[6]通过实验研究建立了蜂窝纸箱的力学模型,较好地解释了其静态压缩过程。张安宁等[7]对多层叠加蜂窝纸箱的压缩特性进行了理论分析和不同速率下的静态压缩实验。潘道津等[8]通过静态压缩实验和动态少压缩实
The invention and application of cellular technology has a history of more than 60 years, began in the military, after used for civilian goods [1]. Military and civilian goods are using honey honeycomb core, through the composite timber. Military is using aluminum alloy as a raw material, the civilian goods is paper as raw material, the base principle of wood is the same. After the second world war, the honeycomb sandwich materials developing rapidly in the developed countries, especially the Netherlands, the UK, technology and equipment modernization level is high, product quality is stable, in the aerospace, aviation, construction, packaging, transportation and so on many areas has been widely used [2], the corresponding assembly technology is also very perfect. In recent years, the application of honeycomb carton also got rapid development in our country. In the development of equipment and products, all made significant achievements. The applied honeycomb carton packing to improve office have been the focus of the improvement in China, and the honeycomb composite packaging materials meeting for many times, support application [3] as soon as possible in our country. In 1998, 1999 and 1998, the state economic resources comprehensive utilization and environmental protection, the national development planning committee members have an important announcement respectively, make clear a regulation honeycomb carton as an important technology to focus on developing countries [4]. Some domestic experts and scholars made some meaningful work in this respect. For example: the Lord [5] by less static compression experiment studied the cushioning property of honeycomb cardboard box. Yan-feng guo [6], such as honeycomb carton mechanical model was established based on experimental research, better explained, the static compression process. Zhang peace [7] to multilayer superposition of compression characteristics of honeycomb carton has carried on the theoretical analysis and static compression test under different rate. Pan tao jin [8], such as less by static compression test and dynamic compression
蜂窝纸箱的主要成分是纸张及构成纸张的填料和胶料,它们各有不同的物理属性,从而使纸张的力学特性既不同于弹性物体或塑性物体,又不同于理想的流体。当纸张受力变形时,既会呈现弹性变形的某些特征,又会呈现流体的粘性,称之为粘弹性现象。按流变学观点纸缓冲材料具有粘弹塑性。也就是说,它可以假定是由弹性、粘性、塑性二要素所构成的物质。蜂窝纸箱作为一种缓冲包装材料,是包装物品在流通过程中受到外力的作用而遭受到冲击和振动时,能吸收外力产生的能量,防止产品遭受破坏,他是具有高度压缩和复原性的粘弹性材料。 构成蜂窝纸箱的主要成分,是高分子材料,因此,蜂窝纸箱具有典型的高分了材料所具备的粘弹性。它是一种兼有某些粘性液体和弹性固体特性的材料。粘性液体在的承受能力状况下具有损耗能量的能力,而不能贮存能量;相反,弹性材料能贮存而不能损耗能量。蜂窝纸箱的特性介于两者之间,当它产生动态的应力σ与应变ε时,部分能量可以贮存起来,另一部分能量则被转化成热量而被耗散掉。 蜂窝纸箱主要由高分了聚合物构成,从它受力后的微观表现可以分析它的耗能特性。当它受到外力时,一方面分了链可以变形,另一方面会产生分了与分了之间链段的滑移。当外力除去后,变形的分了链要恢复原位,释放外力所做的功,这就是粘弹体的弹性。但分了链的滑移不能完全恢复原位,会产生的变形,这就是粘弹体的粘性。这一部分做的功变为热量,耗散于周围环境中,使机械振动能转变为热能。 蜂窝纸箱中的固相成分虽然都是高分子有机物,但是在蜂窝纸箱的结构成分中气体占有大部分的体积,蜂窝纸箱中的气体对蜂窝纸箱的特性有着很大的影响。
The main components of the honeycomb carton packing and is made by the paper and paper sizing, each with different physical properties, so that the mechanical properties of the paper is different from both elastic object or plastic, and different from the ideal fluid. When paper stress deformation, both can present some of the characteristics of elastic deformation, and can present the viscous fluid, called the viscoelastic phenomenon. According to the rheology view paper cushioning material viscoelastic plasticity. That is to say, it is to be assumed by the elasticity, viscosity, plastic substances consisting of two elements. Honeycomb cardboard box as a kind of cushion packaging material that is packaged goods in circulation process by external and subjected to the action of shock and vibration, can absorb energy force, prevent product damage, he is highly compressed and resilience of viscoelastic materials. Constitute the main components of the honeycomb cardboard box, is a polymer material, therefore, the honeycomb carton with typical high score of viscoelastic material. It is a combined some viscous liquid and the characteristics of the elastic solid material. Viscous liquid in a certain tolerance condition has the ability of energy dissipation, and cannot be stored energy; On the contrary, the elastic material can be stored and not loss of energy. Characteristics of honeycomb cardboard in between, when it produces the dynamic stress of the sigma epsilon, and strain energy can be stored, another part of the energy is converted into heat and is wasted. Honeycomb carton is mainly composed of high polymer composition, from the microcosmic performance of it can analyze its energy consumption characteristics. When it is under the external force, on the one hand, got the chain can deformation, on the other hand will produce chain segment of slip between points and points. When external force is removed, the deformation of points to restore the chain in place, release the external force the work done, this is the elasticity of the viscoelastic body. But got the chain slip cannot be fully recovered in situ, can produce a permanent deformation, this is the viscous viscoelastic body. Do this part of the work to heat dissipation to the surrounding environment, make the mechanical vibration energy into heat energy. Even though the solid phase composition in honeycomb carton is a macromolecule organic matter, but in the structure of honeycomb carton component occupies most of the volume of gases, the gases in the honeycomb carton has a great influence on the characteristics of the honeycomb cardboard box.
