Zinc Oxide Rubber Activator (ZnO Sulfur-Cure Vulcanization Activator) Storage

Storing Zinc Oxide Rubber Activator? Start Here

If you're working with zinc oxide rubber activator, you're likely in the business of making something durable and flexible, like tires or rubber goods. This chemical is a key player in the rubber compounding world, helping to activate sulfur curing and stabilize heat. Whether you're handling it as a powder or a slurry, knowing how to store it properly is crucial to keeping your operations smooth and efficient.

Can you store it in a poly tank?

Yes, you can store zinc oxide slurry in a polyethylene tank. HDPE and XLPE tanks are excellent choices for handling ZnO slurry, thanks to their smooth walls that make cleanout easy. For powder, dust control is more important than the tank material, so focus on proper ventilation and handling practices.

Key Issue: Slurry Settling

One of the main challenges with storing zinc oxide slurry is settling and caking. To maintain uniformity, mechanical agitation is necessary. This keeps the solids evenly distributed and prevents the slurry from becoming too thick or difficult to handle.

The safety that actually matters

• Ensure tanks are equipped with proper mechanical agitation to prevent settling.
• Use dust control measures when handling ZnO powder to avoid inhalation risks.
• Regularly inspect and clean storage tanks to maintain material quality and prevent contamination.

Common questions

Can I use a stainless steel tank for ZnO slurry?

Yes, but it's often not cost-effective compared to HDPE tanks for non-product-contact services.

What gaskets should I use?

EPDM gaskets are excellent for ZnO slurry compatibility, but always match gaskets to the manufacturer chart.

How do I prevent slurry from settling?

Use mechanical agitation in your tanks to keep the slurry well-mixed and prevent settling.
