Previously, there was a scarcity of choices, but now it explodes. We witness history and are also creating it. Careful observation of people's clothing, food, housing, and transportation can reveal interesting changes in lifestyle and work, but some emotions and choices remain unchanged.


Changes in Shopping Methods: Grain Ticket Exchange VS Online Ordering

     Changes in Travel Payment Methods: Steel Coin VS Scan Code Payment


Changes in the selection of metallographic consumables: domestic metallographic sandpaper vs imported metallographic sandpaper

     Chain Nengjia imported QMAXIS (Kemai) silicon carbide metallographic sandpaper from the United States with original packaging. The paper base has strong toughness, good water resistance, uniform, dense, sharp distribution of silicon carbide particles, and high removal rate. By grinding the metallographic sample with it, the surface scratches are small, which is beneficial for subsequent polishing processes and can effectively shorten the sample preparation time.

    QMAXIS (Kemai) silicon carbide metallographic sandpaper makes sample grinding no longer difficult, with good results, high efficiency, affordable and easy to use, leading to customer satisfaction. Looking back and experiencing life, looking forward and pursuing life! QMAXIS silicon carbide metallographic sandpaper is my constant choice!
