Product Overview

The KR‑424 laboratory‑grade wet pulp disintegrator is standard‑compliant sample‑preparation equipment built in accordance with ISO 5263 “Pulp — Wet disintegration in the laboratory” requirements. In an aqueous environment, it applies controlled hydraulic‑mechanical agitation to untangle inter‑woven pulp fibre bundles into individual fibres, while preserving original fibre morphology and intrinsic physical‑chemical properties as much as possible.

Well‑prepared disintegrated pulp suspension delivers consistent, trustworthy baseline data for downstream pulp‑performance testing. This unit is widely deployed in pulp‑and‑paper mills, fibre‑material research institutes and accredited quality‑inspection laboratories for preparing standard pulp suspensions for hand‑sheet making, freeness testing and fibre‑screening analysis.

Core Product Competitive Advantages

1. Strictly Standard‑Matched Mechanical Geometry The stainless‑steel mixing vessel, four‑piece internal spiral baffles and three‑bladed impeller all follow ISO 5263 dimensional specifications. Fixed distance between impeller blades and tank bottom guarantees uniform fluid‑shear field, avoiding excessive fibre cutting or incomplete fibre separation across test batches.
2. Stable Constant‑Frequency Agitation System Precision‑controlled motor maintains impeller rotary frequency at 49 ± 1.5 r/s. Top‑view clock‑wise rotation generates ordered circulating flow inside the tank. It prevents pulp from idle‑spinning together with the impeller and achieves homogeneous fibre dispersion effect.
3. Intuitive LCD Human‑Machine Control Panel Digital LCD interface displays runtime and revolution‑count status. Operators configure working parameters via front‑panel buttons. The equipment will automatically halt upon completing preset disintegration cycles, eliminating manual timing errors and simplifying repeat‑sample workflows.
4. Robust Compact Bench‑Top Cabinet Construction Integrated compact cabinet layout occupies limited laboratory bench‑space. Tank assembly can be easily detached for thorough cleaning of residual pulp fibres. Low‑maintenance mechanical design lowers daily lab‑operation workload.
5. Reproducible Sample‑Preparation Results Thanks to standardized tank‑baffle‑impeller geometry and steady‑speed drive, parallel‑group disintegration delivers good repeatability. It minimises human‑introduced variation for pulp‑R&D and routine QC‑lab sample‑making work.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Place disintegrator on level lab bench. Check tank, baffles and impeller for residual pulp deposits, clean thoroughly. Weigh pulp sample according standard formulation and add corresponding volume of purified water into the vessel. Secure mixing‑tank in correct mounting position.
2. Parameter Configuration Power‑on unit. Set target disintegration revolution count via LCD control panel according to applicable pulp‑test standard.
3. Pulp Wet‑Disintegration Process Initiate start command. Impeller rotates at specified constant speed to generate circulating hydrodynamic shear force, gradually untangling fibre bundles into well‑dispersed single‑fibre suspension. The machine will automatically stop once reaching preset revolution value.
4. Retrieve Prepared Pulp Suspension After full disintegration finishes, unlock and take down mixing tank. The homogeneous pulp suspension can be directly used for hand‑sheet forming, freeness measurement, fibre‑screening or other subsequent pulp‑characterisation experiments.
5. Post‑Test Cleaning & Shutdown Completely rinse tank, baffles and three‑bladed impeller to remove leftover fibre residues. Re‑assemble components. Shut‑off main power supply after finishing batch‑sample preparation.

Safety‑Operation‑Reminder

Do not open tank lid or reach into vessel while impeller is rotating. Disconnect power before performing disassembly‑cleaning work. Inspect impeller and baffles regularly for wear‑and‑tear to guarantee disintegration‑quality consistency.
