Flocculation performance of a cationic biopolymer derived from a cellulosic source in mild aqueous solution - ScienceDirect
As a reference polymer for the flocculation study, a cationic polyacrylamide (CPAM) with a molecular weight of 1.5 × 10 6 g/mol and CD of 4 mekv/g from Kemira, Finland was used. 2.2. Synthesis of cationized cellulosic flocculant Water-soluble ca
A novel cationic polymer with long side chains (2,3-epoxypropyltrimethyl ammonium chloride (ETA) modified chitosan-graft polyacrylamide, typically denoted as CTS-ETA- g -PAM) was prepared by grafting acrylamide onto the ca tionic modified
The Salt-Free Dyeing on Cotton: An Approach to Effluent Free Mechanism; Can Chitosan be a Potential Option?
3. Modification of cellulose or Cationization of cotton: Using Chitosan (polyacrylamide) In this process a new fiber modification technique based on cationic acrylic copolymer is retreated with cotton fiber because it believed that pre-treated
Highly charged, cationic cellulose-based polyelectrolytes (PELs) from birch wood pulp were produced by Sirviö et al. 6 and Liimatainen et al. 7 The raw material was firstly oxidized with periodate, leading to the formation of dialdehyde cellulos
Dewatering of softwood kraft pulp with additives of microfibrillated cellulose and dialcohol cellulose :: BioResources
All pulps including MFC were used together, during vacuum dewatering, with 0.1% of the dry-weight of the retention aid, cationic polyacrylamide (C-PAM). The C-PAM (Core Shell TM 74553, Nalco, Naperville, IL, USA) was added to the stock and the
Carboxymethyl cellulose (CMC)-rich cellulose sheets were prepared with a cationic retention aid, poly[N,N,N-trimethyl-N-(2-methacryloxyethyl)ammonium chloride] (PTMMAC), using a papermaking technique.
Overview of nanocellulose as additives in paper processing and paper products - De Gruyter
Cellulose is a linear biopolymer, which occurs naturally in all plants. In the early nineteenth century, the chemical structure of cellulose was confirmed, followed by in-depth research activities. The linear polymer in cellulose is linked by
Polyacrylamide (PAM) is a commercially relevant cationic polymer utilized mainly for water treatment due to its high efficiency and rapid dissolution. Being a cationic polymer, PAM can increase the settling rate of bacterial floc and improve the

- How does dispersant affect the processing of a ceramic part?
- The choice of dispersant can impact on several parameters in the processing of a ceramic part, but the key properties are to produce consistent pastes/slurries with low viscosity and enable de-aeration of the slurry, thus reducing any batch variations and improving flow and fill into the molds to reduce gaps or defects.
- Can Lubrizol dispersants be used in decorative ceramics?
- Several years ago, Lubrizol began looking at using dispersants in decorative ceramics. While this application was changing from traditional analog printing to a digital printing system, this created good potential for using Lubrizol dispersants to create better products.
