Polyvinyl Alcohol (PVA) FAQ: Technical FAQ
-
Q1: What is the primary material composition of Polyvinyl Alcohol (PVA)?
A: Polyvinyl Alcohol (PVA) is a synthetic polymer derived through the polymerization of vinyl acetate, followed by partial or full hydrolysis, resulting in white flakes or powder. (See reference) -
Q2: What are the standard grades and specifications for Polyvinyl Alcohol (PVA)?
A: PVA is categorized by degree of polymerization (500–3500) and degree of hydrolysis (87–99+%), each grade suited for specific applications like films, adhesives, and fiber manufacturing. -
Q3: What is the typical installation standard or protocol for PVA usage in construction?
A: In construction, PVA is mixed with cement mortar or plaster under standardized dosages (typically 0.1–0.5% by mass), ensuring enhanced bonding and flexibility according to ASTM C1059 (ASTM International). -
Q4: What is the significance of the Hydrolysis Degree in Polyvinyl Alcohol?
A: The degree of hydrolysis determines the water solubility and chemical reactivity. Fully hydrolyzed PVA is less soluble at room temperature but offers greater tensile strength, while partially hydrolyzed grades dissolve quickly. -
Q5: What technical standards should be followed for PVA in adhesives?
A: Adhesive-grade PVA should comply with ISO 14021:2016 & GB/T 12010 standards, emphasizing purity, viscosity, and degree of polymerization. -
Q6: What parameters affect PVA’s performance in textile sizing?
A: Parameters include molecular weight, viscosity in solution, and residual acetyl content—directly impacting film formation, thread protection, and washing-out behavior. -
Q7: How is PVA environmentally friendly?
A: PVA is water-soluble, non-toxic, and biodegradable under appropriate conditions, making it a suitable replacement for petrochemicals in green applications (ACS Applied Polymer Materials).
