Blaine Air Permeability Filter Paper (1000/Pk)

Blaine Air Permeability Filter Paper – 1000/Pack

Precision-Grade Filter Paper for Cement Testing

Blaine Air Permeability Filter Paper is a single-use, 12.7mm (0.5in) Grade 597 filter paper designed for use with the Blaine Air Permeability Apparatus. It supports accurate testing of cement fineness and ensures consistent airflow during laboratory analysis.

Each sheet is manufactured for uniform thickness to help reduce testing variability and improve repeatability.

Why Uniform Filter Paper Matters

During Blaine testing, new filter papers are placed on the perforated disc and leveled cement multiple times. Because filter paper thickness can affect airflow, uniform papers are essential for accurate results.

Best practices include:

• Using fresh filter paper for each test
• Testing multiple samples for consistency
• Avoiding reused or uneven papers

Key Features

How the Blaine Air Permeability Test Works

The Blaine Air Permeability Apparatus determines cement fineness by measuring the specific surface area of fine materials in square centimeters per gram.

The test works by:

• Drawing air through a cement bed with known porosity
• Measuring airflow rate through the sample
• Calculating surface area based on air resistance

Airflow rate and pressure drop are directly related to particle size and pore volume.

Test Accuracy and Data Analysis

Results from the apparatus help confirm cement fineness and filter performance. Repeated measurements are used to calculate standard deviation, showing test consistency.

Important factors include:

• Airflow rate
• Pressure drop
• Pore size
• Filter thickness

Empirical models and equations may be used to predict air permeability. Results are commonly tabulated for easy comparison between samples.

Applications of Air Permeability Testing

Air permeability plays a vital role in:

• Cement quality control
• Laboratory testing
• Product development
• Industrial filtration

It helps evaluate:

• Flow resistance
• Filtration efficiency
• Material consistency

Key Properties Affecting Air Permeability

Several material characteristics influence air permeability:

• Pore size – affects particle retention
• Porosity – controls airflow rate
• Basis weight – impacts density
• Fiber diameter – affects pore structure

These properties are measured using standardized test methods.

Maximum Pore Size and Performance

Maximum pore size affects both airflow and filtration efficiency.

• Larger pores allow higher airflow
• Smaller pores improve filtration
• Measurement methods include porometry and bubble point testing

Choosing the correct pore size ensures optimal performance for the intended application.
