(1)材料的固有特性 材料的出有特性此满足特有功能、使用环境、作业条件和环境保护的需要。
(1) the intrinsic properties of the material have the characteristics that meet the special functions, the use environment, the operating conditions and the environmental protection.
无论怎样的双头锯产品,都必须首先考虑产品应具有怎样的功能和所期望的使用寿命,这样的考虑必定会在选用何种材料更合适方面做出总的指导。
No matter what kind of double headed saw products, we must first consider what kind of function and expectation of service life the product should have. Such considerations will definitely give general guidance in selecting materials that are more suitable.
(2)材料的工艺性 材料成形工艺的选择原则是高效、优质、低成本,即应在规定的周期内,经济地生产出符合技术要求的产品,其核心是产品品质。材料应具有良好的工艺性能,符合造型设计中成形工艺、加工工艺和表面出现的要求,应于加工设备及生产技术相适应。
(2) the selection principle of material processing technology is high efficiency, high quality and low cost. That is to say, products that meet the technical requirements should be produced economically in the prescribed period, and the core is product quality. Materials should have good technological properties, conform to the requirements of forming process, processing technology and surface appearance in molding design, and should be suitable for processing equipment and production technology.
(3)材料的外观 产品的外观在一定程度卜受其可见表面的影响,并受材料所能允许的制造结构形式的影响。出此,外观也是材料选择应考虑的—个重要因素。就产品的表面效果来看,材料还影响着表而的自然光泽、反射率与纹邵,影响着所能采用的表面装饰材料和方式,影响着装饰的外观效果和在使用期限内的恶化程度与速度c
(3) the appearance of the appearance of the material is influenced by the visible surface to a certain extent, and is influenced by the form of the manufacturing structure that the material can allow. In this case, the appearance is also an important factor to be considered in the selection of materials. As for the product's surface effect, the material also affects the natural luster, reflectivity and tattoo of the table, affecting the surface decoration materials and methods that can be adopted, affecting the appearance effect and the deterioration degree and speed of the decoration during the use period. C
(4)材料的生产成本及环境因素 材料的生产一使用—废弃的过程,是一个将大量的资源从环境中提取,再将大旦废弃物徘回环境中去的恶性循环过程。在满足设11要求的基础卜,尽量降低材料成本,优先选用资源干富、价格低廉、有利于生态环境保护的材料。
(4) the material production cost and environmental factors using waste materials production process, is a large amount of resources extracted from the environment, then the process once hovering vicious spiral waste to environment. In meeting the foundation of the 11 requirements, the cost of material is reduced as much as possible, and the materials which are rich in resources, low in price and beneficial to the protection of the ecological environment are preferred.
(5)材料的创新 随首科学技术水平的发展,新材料、新技术的不断出现势在必然c当一种新的材料出现后,需要创新性使用,来创选出一种新的形态方式,赋予产品新的品
(5) material innovation is developing with the development of science and technology. The emergence of new materials and technologies is inevitable. C, when a new material appears, it needs innovative use to create a new form of form and give products new products.
质和内涵。新材料的出现为产品设汁提供更广阔的前提,满足产品设计的要求。
Quality and connotation. The appearance of the new material provides a broader premise for the production of the product, and meets the requirements of the product design.
