The National Day express delivery package contained a steam generator.

With the National Day holiday approaching, the express delivery industry is experiencing a peak season, and corrugated cardboard, a reliable partner in express delivery, is playing a busy role. From fresh produce gift boxes to appliance parcels, sheets of corrugated cardboard act as protective armor, and behind the scenes, steam generators have been ensuring the efficient production of corrugated cardboard.The strength of corrugated paper comes from its regular corrugated structure, which relies on the precise heating provided by the steam generator. On the production line, the high-temperature, high-pressure steam generated by the steam generator quickly heats the corrugated rolls to 160-180℃, allowing the flat core paper to be easily shaped during rolling. Combined with mechanical pressure, this forms a tough and sturdy wavy pattern, preventing "collapsed corrugations" and "missing corrugations" from the source, ensuring that the corrugated paper can withstand the weight of various express deliveries.Express packaging requires extremely high bonding strength for corrugated paper. After the core paper and face paper are bonded with starch adhesive, a steam-heated drying device can quickly raise the temperature to 120-150℃ in 28 seconds, rapidly evaporating moisture and curing the adhesive layer. Even if the production line speeds up due to peak express delivery periods, the risk of "glue separation" can be avoided, preventing the cardboard from becoming brittle or deformed due to moisture. Furthermore, the corrugated paper production line can operate 24 hours a day without interruption.Faced with a surge in orders, steam generators ensure greater production stability. They use low-pressure, high-temperature, 100% dry, slightly superheated steam to dry the paper, stabilizing its moisture content within the optimal range of 6-8%, thus reducing breakage during forming. Steam generators are smaller, more flexible in starting and stopping, and can infinitely adjust steam output from 25% to 100%, avoiding energy waste. In contrast, steam boilers are bulky, typically require 30 minutes of preheating, and can only operate at full capacity continuously. Even with fluctuations in order volume, they cannot be flexibly adjusted, resulting in significantly higher energy consumption than steam generators.It can be said that the steam generator is the core power source for the efficient production of corrugated paper. Under the pressure of the National Day express delivery peak, its stable heating and reliable performance give corrugated paper the confidence to bear and protect it, building a solid first line of defense for the safe transportation of massive amounts of parcels.
