2 Waste Milk Pack Pulp 80% polyethylene (Lamination) 20%  Chemical Reagents Pulp  Disk Refining  Cleaner  Screening Pulp PE Cracker PE Treatment on Commission Burning Stuff Box  Dewatering  Drying Recycled Fine Pulp

3 Pulp  -Cellulose Hemicellulose Lignin Cellulose ester: cellulose acetate cellulose sulfate cellulose nitrate NaOH Cellulose ether: methyl cellulose ethyl cellulose carboxymethyl cellulose (CMC) etc: cyanoethylcellulose cellulose ether from reaction with epoxide graft compound with cellulose or its derivatives

4 Cellulose NaOH solution Na-celluloseCellulose Derivatives Sodiumchloroaceticchloride Carboxymethylcellulose, Sodium Salt (CMC) Polymer Blend Graft polymerization Hygroscopic Polymer Food and pharmaceutical products Dyestuff printing paste Paper sizing Cosmetics Binder in enamels

5 Hygroscopic Polymer Uses 위생재, 농업, 원예, 식품 유통, 토목, 건축, 화장품, 의료용, 도료, 접착 Synthesis Graft Polymerization Cross-linked Polymerization 3-Dimension Reaction of Hygroscopic Polymer Self Crosslinked Polymerization * Cellulose 계 관련 고흡수성 고분자 화합물 (1) Cellulose/PAA (2) CMC/ 자기가교 또는 가열불용화 (3) 재생 cellulose 섬유 /Na-PAN
