The performance of a paper shredder should be inspected in terms of durability, confidentiality, security and ease of use. The first is the degree of durability: a shredder to maintain a satisfactory service life in addition to the quality of components, the choice of cutting tools is particularly important. At present, strong carbonized steel knives are the first choice, because only carbonized knives can be durable and greatly reduce the wear rate, so that the knives will not be quickly passivated. Moreover, the functions of shredding credit cards and shredding discs are gradually being paid attention to by consumers, and the requirements for knives will become higher and higher. Therefore, strong carbonized steel knives are indispensable for shredders.

Second is the degree of confidentiality: it should be said that the shredder is accompanied by the concept of secrecy, and is also developed according to the continuous upgrade of confidentiality requirements. Then, when buying a shredder, consumers are more concerned about this shredder The confidentiality of the machine. As far as consumers can see, the shredding method and shredding effect are a key indicator to distinguish the degree of confidentiality. There are three types of shredding methods: granular, segment, and strip. The shredding effect refers to the above The particle size of paper shredded in the three paper shredding modes. As we all know, the granular level of confidentiality is the highest, but from the concept of environmental protection, the smaller the paper is shredded, the greater the probability of flying paper cutting, so it is not conducive to environmental protection, and from the durability of the machine, the granular shredder The cutters are more prone to wear, so consumers are advised to choose the shredding method according to the confidentiality requirements of the documents. Use granular shredders where confidentiality is high, such as military documents and important financial data. General document destruction Optional segment and strip shredders are available.
