Overview
The PL28-2 Standard Pulp Disintegrator is a laboratory instrument designed for the standardized wet disintegration of pulp samples. It uses high-speed agitation in water to separate interwoven fiber bundles into individual fibers while minimizing changes to their original properties.
Also known as a Laboratory Pulp Disintegrator or Standard Fiber Disintegrator, the equipment is suitable for pulp and paper laboratories, paper mills, research institutes and educational laboratories.
The PL28-2 is designed according to JIS P8220, TAPPI T205 and ISO 5263 and can be used to prepare pulp samples for subsequent laboratory testing, such as handsheet preparation, freeness testing and pulp screening.
Unlike a pulp refiner or beater, the primary purpose of a pulp disintegrator is fiber separation and dispersion rather than modifying fiber properties.
Working Principle
A measured quantity of pulp is placed into the disintegration vessel with a specified volume of water. The high-speed propeller generates controlled turbulence and mechanical agitation, separating interconnected fiber bundles into individual fibers.
The standard test condition uses 24 g oven-dry pulp at 1.2% consistency in 2,000 mL of water. The propeller rotates at 3,000 rpm ± 5 rpm, with a standard total of 50,000 revolutions.
The PL28-2 adopts a vertical structure. The disintegration vessel is vertically suspended below the drive system, making the equipment simple to operate and convenient for standardized laboratory testing.

Frequently Asked Questions
Q: What is a Pulp Disintegrator used for?
A Pulp Disintegrator separates interwoven pulp fibers in water to produce a uniform pulp suspension for standardized laboratory testing.
Q: What is the difference between a Pulp Disintegrator and a Pulp Refiner?
A Pulp Disintegrator is primarily used to separate and disperse fibers while minimizing changes to their original properties. A Pulp Refiner applies mechanical treatment to modify fiber characteristics and refining performance.
Q: Which standards does the PL28-2 follow?
The PL28-2 is designed according to JIS P8220, TAPPI T205 and ISO 5263.
Q: What is the standard pulp sample?
The standard test condition uses 24 g oven-dry pulp at 1.2% consistency in 2,000 mL of water.
Q: What is the standard rotation speed?
The standard rotation speed is 3,000 rpm ± 5 rpm, with a standard revolution count of 50,000 revolutions.
