Flagship continuous machine for high-efficiency batch deacidification & consolidation of single-sheet paper — up to 3,000 A4 sheets/hour with automated PLC control.

3,000 sheets/hr View Details

Whole-Volume Deacidification Machine

Designed for complete books and archival volumes. No page disassembly required — simply load the entire volume for permeation deacidification treatment. Simple to operate, safe and efficient.

Whole-Volume Processing

Batch Whole-Volume Deacidification Machine

Designed for large-scale batch volume processing — handles multiple volumes simultaneously to dramatically increase throughput. Ideal for large archives and libraries.

Batch High-Efficiency

Mist High-Efficiency Deacidification Machine

Advanced atomization technology converts deacidification reagents into ultra-fine particles that deeply penetrate paper fibers, achieving precise and highly efficient deacidification protection.

Mist Precision

Mist Fine-Precision Deacidification Machine

Designed for rare documents and ancient manuscripts requiring delicate handling — provides more precise parameter control to ensure the most careful protection for valuable materials.

Fine-Precision Processing

Mist Calligraphy & Painting Deacidification Machine

Specifically designed for flat-spread artworks including calligraphy, paintings and rubbings — a special atomization approach completes deacidification while preserving the original form of the artwork.

Calcium-Based Deacidification Reagent

Green & Safe Calcium-Based Reagent

Water-based calcium formula — green, safe and eco-friendly, posing no harm to operators or original documents

Product Features

ZHONGCAI's calcium-based water reagent is formulated on a calcium bicarbonate/calcium hydroxide system that effectively neutralizes acidic compounds within paper fibers and creates an alkaline buffer reserve, slowing re-acidification over time.

Green water-based formula — no organic solvents
Completely safe for operators
Does not affect document color or text
Long-lasting and stable deacidification effect

Environmental Advantages

Compared to traditional organic solvent-based reagents, ZHONGCAI's calcium-based reagent is entirely water-based — no harmful vapors are emitted during use, the working environment is not contaminated, waste liquid is easy to handle, and truly green deacidification is achieved.

Zero organic solvent emissions
Simple and safe waste liquid disposal
Meets environmental discharge standards
Usable in standard indoor environments

pH Non-Destructive Intelligent Testing System

Smart & Precise pH Detection

Integrates moisture-locking, positioning, cleaning, data storage and intelligent transmission — quick, precise and safe

Moisture-Locking Technology

A unique moisture-locking mechanism ensures uniform hydration of the paper surface during testing, preventing localized over-wetting that could damage documents.

Precision Positioning

An accurate positioning system ensures consistent measurement locations across tests, enabling reliable before-and-after comparisons to track deacidification effectiveness.

Automatic Cleaning

Built-in automatic probe cleaning after each test prevents cross-contamination and ensures measurement accuracy across consecutive samples.

Data Storage

Automatically stores every test result, building a complete detection archive that provides data-driven support for document preservation decisions.

Intelligent Transmission

Supports wireless data transmission and seamless integration with management systems — real-time synchronization of test results for remote management and analysis.

Non-Destructive Testing

Innovative non-destructive detection method — the testing process causes no damage to original documents, providing full protection for precious collections during assessment.
