Dryer sticking and dusting lead to sheet breaks, reduced production efficiency, and poor finished product yield. A poorly chosen or misapplied mineral oil release agent can fail to provide adequate release, leave oil spots, or even increase doctor blade wear.
PR-08 Mineral Oil Release Agent from Luterra Advanced Materials is a new generation specialty papermaking additive formulated with mineral oil, fatty acid esters, and various high-quality natural imported raw materials. It forms a uniform protective film on the dryer surface, significantly reducing wear and ensuring continuous, stable operation. This guide covers five critical mistakes to avoid when selecting and using a mineral oil release agent.
Mistake #1: Choosing a Release Agent That Leaves Oil Spots on the Paper Surface
A common complaint with traditional oily release agents is the formation of oil spots due to their strong hydrophobicity, especially if they don't disperse evenly.
PR-08 uses an optimized formulation to ensure even dispersion on the paper surface without leaving any oil spots. It also effectively reduces paper dust generation, improving the overall quality of the finished product.
Mistake #2: Overlooking the Impact on Doctor Blade Wear
Some release agents, while providing adequate release, can accelerate doctor blade wear and vibration, leading to more frequent blade changes and increased maintenance costs.
PR-08 forms a uniform protective film on the dryer surface that significantly reduces wear between the dryer surface and doctor blades, ensuring continuous and stable operation of the production line. This extends blade life and reduces downtime.
Mistake #3: Using a Product That's Only Suitable for a Limited Range of Dryer Types
Different mills use different dryer materials, including cast iron and stainless steel. A product formulated for one type may be incompatible with another.
PR-08 is compatible with various dryer materials including cast iron and stainless steel. It also provides lubrication and protection for creping doctor blades, extending equipment life across the entire dryer section.
Mistake #4: Using the Wrong Dilution or Application Method
Mineral oil release agents are concentrates and must be properly diluted and applied to be effective. Using them neat or in the wrong dilution can cause uneven coverage, oil spots, or waste.
For optimal results with PR-08:
Spray onto Yankee Dryer Surface: Dilute 50–200 times with water, then spray evenly onto the dryer surface for rapid lubrication and release.
In-line Dilution / Pulp Addition: Suitable for in-line dilution systems on production lines; can be added directly to the pulp system for flexible process control and precise adjustment.
Dosage: 0.5–1 kg per ton of paper, adjusted based on basis weight, machine speed, and paper width.
Mistake #5: Ignoring the Versatility Across Paper Grades
Some release agents are limited to a narrow range of paper grades, requiring multiple products for different production runs.
PR-08 is fully adaptable to the production of various paper grades including writing paper, duplex paper, tissue paper, lightweight paper, aluminum foil backing paper, corrugating medium, linerboard, fruit wrap paper, and ritual paper. This versatility simplifies inventory and process management.
