The application discloses a method for quality prediction of tinplate cans based on iron ion migration amount, which comprises the following steps: sealing and soaking the tinplate cans filled with acetic acid, and performing temperature acceleration test; sampling on the third day of the temperature acceleration test, and detecting the iron ion migration amount; sampling on the tenth day of the temperature acceleration test, and detecting the iron ion migration amount; and predicting the quality of the tinplate cans based on the iron ion migration amounts on the third day and the tenth day. The application takes the migration amount on the third day as a short-term risk indicator, and takes the migration amount on the tenth day as a key quality determination standard of long-term stability indicator. Based on the detection results of the two time points, the iron ion migration trend of the tinplate cans within a six-month shelf period can be reliably predicted, the sensory quality and stability of beer products can be ensured, clear and quantitative delivery access conditions of suppliers can be set according to the detection results, the risk of beer quality deterioration caused by quality problems of packaging materials can be avoided from the source, early prediction and precise control of the quality of packaging materials are realized, and the overall quality management level is improved.

The utility model discloses an identification PCCP (prestressed concrete cylinder pipe), which relates to the technical field of concrete prefabricated parts and comprises a PCCP frame and an integrally formed concrete chip arranged on the PCCP frame. The PCCP frame comprises a peripheral steel cylinder, a pipe core outer wall concrete layer wrapping the peripheral steel cylinder, a prestressed steel wire wound around the periphery of the pipe core outer wall concrete layer, a mortar protection layer wrapping the prestressed steel wire and a pipe core inner wall concrete layer arranged on the inner side of the peripheral steel cylinder. The integrally-formed concrete chip is arranged on a peripheral steel cylinder at the socket end of the PCCP pipe frame and / or a concrete layer on the inner wall of the pipe core; the integrally-formed concrete chip is arranged in the identification PCCP pipe, so that identification and traceability management are facilitated. The PCCP information recording device is simple in principle and obvious in effect, can be effectively suitable for PCCPs with different information recording requirements, marks and traces the PCCPs at the same time, and remarkably improves the quality management level of concrete products or structures.
