Basic Core Definition
Core Components: Composed of a chemical adhesive tube (containing vinyl resin, quartz sand, and hardener), screw, washer, and nut. Anchoring is achieved through chemical reaction curing, rather than physical expansion and compression.
Core Characteristics: Excellent acid and alkali resistance, aging resistance, and seismic performance; no expansion or compression stress on the substrate; smaller requirements for installation spacing and edge distance.
