Rivets are permanent fasteners that join materials by means of a mechanical interlock. They consist of a cylindrical shaft with a head at one end and are installed by deforming the unheaded end after insertion. Rivets are commonly used in structural applications such as bridges and aircraft, where a high level of strength is critical. There are different types of rivets, including solid rivets, blind rivets, and tubular rivets. Blind rivets, also known as pop rivets, can be installed from one side of the workpiece, making them ideal for applications where access to both sides is limited.

  • （1）HPMC or Hydroxypropyl methylcellulose (INN name: Hypromellose), also simplified as hydroxypropyl methylcellulose (HPMC), is a kind of non-ionic cellulose mixed ether. It is a semi-synthetic, inactive, viscoelastic polymer. Hydroxypropyl methylcellulose is widely used in construction, food, medicine, and other industries.

  • Hydroxypropyl methyl cellulose (HPMC) is a cellulose derivative that was first developed and used in industrial and food applications starting in the 20th century. Its exact origin in terms of discovery and initial development is difficult to attribute to a single individual or organization, as research and development of cellulose derivatives has involved many scientists and companies at different times.

    HPMC is produced through a chemical process known as etherification, in which natural cellulose is treated with hydroxypropyl chloride and sodium methoxide. This process alters the chemical structure of cellulose, making it water-soluble and giving it desired properties as a thickener, stabilizer and film-forming agent.

    Production and Use over Time:

    The use of HPMC in industrial and food applications has grown significantly since the mid-20th century, when researchers began to more fully explore the potential uses of cellulose derivatives.
