Question 1

Why are fiberglass filter bags preferred in cement kilns?

Accepted Answer

Cement kilns generate extremely hot gases (200°C+) containing acidic compounds. Woven fiberglass bags resist high temperatures and chemical degradation at a lower cost than synthetic polymers like PTFE.

Question 2

What is the purpose of SGT (Silicone Graphite Teflon) treatment on fiberglass?

Accepted Answer

Woven glass fibers are brittle and can self-abrade. SGT treatment lubricates the glass yarns, preventing mechanical wear and extending bag life under reverse-air flexing.

Question 3

How does high moisture affect fiberglass filter bags?

Accepted Answer

Standard fiberglass can suffer from acid hydrolysis when gas moisture combines with sulfur oxides. Our specialized acid-resistant chemical coatings protect the glass fibers from acid attack.

Question 4

What are the installation requirements for fiberglass bags?

Accepted Answer

Fiberglass bags must be installed with exact tensioning to prevent bagging or sagging. In pulse-jet baghouses, they require wire cages with 20+ vertical wires to distribute support.

Question 5

Can fiberglass bags capture sub-micron carbon black or fly ash?

Accepted Answer

Yes, when laminated with our premium micro-porous ePTFE membrane, fiberglass bags easily trap sub-micron particles, ensuring clean stack emissions.
