3. Cellosize HEC Manufacturing Process—From Raw Material to Quality Product

Manufacturing Flowchart

1. Alkalization of Cellulose
High-grade cellulose fibers are treated with caustic soda in a controlled reactor. → 2. Etherification with Ethylene Oxide
Alkalized cellulose reacts with ethylene oxide, introducing hydroxyethyl groups (controlled by MS parameter). → 3. Washing & Neutralization
Residual chemicals and by-products removed; ISO/ANSI validation. → 4. Drying & Milling
CNC-guided mills set uniform particle size (80–120μm). → 5. Sieving & Quality Control
Batch-wise sampling for ISO 9001:2015 & ANSI/ASTM D1347 checks. → 6. Packaging & Labelling
Dust-free automated packaging; compliance with GHS, ISO, & FDA standards.

Q2: What is the recommended viscosity for architectural coatings?
A: HEC grades with viscosity in 30,000–60,000 mPa.s (2% sol, 20°C) ensure optimal leveling, anti-sagging, and application brushability for water-based paints.
Q3: Which installation and mixing standards are recommended?
A: For coatings and mortars, follow ASTM D2196 (viscosity measurement), and gradually pre-disperse cellosize hec in water at ~25°C, agitating at medium speed to avoid lump formation (ISO 13007 for construction chemistries).
Q4: How does salt resistance differ from ordinary HEC?
A: Cellosize hec is engineered for enhanced ionic stability, maintaining >90% viscosity even in brine conditions (up to 25,000 ppm NaCl/CaCl₂), outperforming standard hydroxyethylcellulose by 18–22% (see SPE 2023 reports).
Q5: What industry certifications are provided?
A: All HEC batches come with ISO 9001:2015, FDA, and REACH certification. Products for oilfield use are tested per API RP 13B-1 and ISO 13503-2 specs.
Q6: Are there customized HEC solutions for personal care?
A: Yes, low-residue, high-transparency grades are tailored for shampoos, cleansers, and gels that require FDA- or EU cosmetics regulations compliance. Contact technical support for formulation matching.
Q7: What is the typical shelf life and packaging standard?
A: Shelf life is 2–3 years in dry, sealed, PP-lined 25-kg (or 50-lb) bags. Bulk ton-bag packaging and custom labeling available on request (GHS/REACH-compliant).
