理化检测是监测和确保建机产品内在质量的重要手段。发展研制新产品、仲裁试验、产品的引进消化和构件失效分析等都需进行理化检测。加强理化试验工作对提高建机产品的可靠性和使用寿命有着十分重要的意义。长期以来,建筑机械行业不少企业都是重外(外观)轻内(内在质量);重冷(冷加工)轻热(热加工),对出厂的产品检验只注意到表面公差尺寸;忽视产品内部组织和成份。理化试验室因陋就简,不配备必要的专业技术人员,不重视仪器设备的更新,认为理化试验室可有可无,把理化试验室放在从属地位,因此发挥不了应有作用。由于企业的决策者不重视理化检验工作, Physicochemical testing is an important means to monitor and ensure the intrinsic quality of construction products. Development of new products, arbitration trials, product introduction and digestion, and component failure analysis all require physical and chemical testing. Strengthening the physical and chemical testing work is of great significance to improving the reliability and service life of construction machinery products. For a long time, many companies in the construction machinery industry are heavy outside (appearance) light inside (inner quality); re-cooling (cold processing) light heat (hot processing), only checking the surface tolerances on the factory product inspection; ignore the product inside Organization and ingredients. The physical and chemical laboratory is simple due to defects, not equipped with the necessary professional and technical personnel, not paying attention to the renewal of equipment and equipment. It is considered that the physical and chemical laboratory is dispensable, and the physical and chemical laboratory is placed in a subordinate position, so it cannot play its due role. Because corporate decision makers do not attach importance to physical and chemical inspections,
