Resin reactor connection structure and configuration standard Sep 06, 2018

Resin reactors are primarily used in the production of unsaturated polyester resins, rosin resins, epoxies, phenolic resins, alkyds, paints and adhesives. The resin reaction kettle can be standardized and humanized according to the requirements of the production process. The feed control, discharge control, mixing control and other manual and automatic control can be realized during the reaction process.

The resin reaction kettle can be effectively divided into an addition polymer and a polycondensate. The addition polymer refers to a polymer obtained by addition polymerization, and the chemical structure of the connection structure is the same as that of the monomer, such as polyethylene, poly. Styrene, polytetrafluoroethylene, etc. The polycondensate refers to a polymer obtained by a condensation polymerization reaction, and the chemical formula of the structural unit is different from that of the monomer, such as a phenol resin, a polyester resin, a polyamide resin, or the like.

The kettle body of the resin reaction kettle is a cylindrical cylinder with an interlayer, an elliptical bottom, and the top cover is a spherical body with a plurality of orifices, and the two are joined together by a fastener through a flange. The reaction kettle is normally open to the atmosphere, and is used for the production of dehydrated rubber and a reaction kettle using vacuum feed. The negative pressure is generally not more than 0.1 MPa, the thickness of the wall is generally 8-16 mm, and the thickness of the outer wall is 5- 10mm, the larger the volume of the reactor, the thicker the wall.

The rotation of the agitator of the resin reaction kettle is driven by the motor through the reducer. The type of the reducer is mostly a worm gear reducer, which is characterized by simple structure, stable transmission and convenient maintenance. Currently, the ideal reduction gear is the balance needle. The reducer is generally popular due to its compact structure, small size and long service life.
