Professional PVA Defoamer Solution - Chemi Tech Addresses Production Challenges

In the production and application of polyvinyl alcohol (PVA), excessive foam is a common yet critical issue that severely impacts efficiency. Overfoaming leads to reduced equipment utilization, unstable product quality, prolonged reaction cycles, and material waste, directly increasing production costs and delaying deliveries.

To address this challenge, Chemi Tech has developed a specialized series of PVA defoamers. These defoamers are based on modified polysiloxane compound technology, featuring rapid bubble-breaking, long-lasting foam suppression, and excellent compatibility, especially suitable for PVA synthesis and processing under high temperature, high shear, and acidic/alkaline conditions.

The specific solution involves four steps:

Step 1: Problem diagnosis and analysis. Through on-site investigation or sample testing, identify the foam generation stage and root causes.

Step 2: Product selection and trial. Recommend suitable models such as Chemi Tech PVA-101 (aqueous systems) or PVA-202 (high-temperature synthesis systems) based on process conditions.

Step 3: Addition method optimization. Guide customers to adopt drip feeding, pumping, or pre-dilution methods for precise control of addition points and dosage.

Step 4: Effect tracking and adjustment. Conduct regular follow-ups and adjust strategies according to production changes to ensure long-term stability.

An adhesive manufacturer faced severe foam overflow during PVA glue preparation, resulting in over 2 hours of daily equipment cleaning and inconsistent product quality. After using Chemi Tech defoamer PVA-101, foam was completely eliminated within 3 minutes of mixing, with foam suppression lasting over 6 hours, while production capacity increased by about 8%.
