Flocculation (except in polymer science) Process of contact and adhesion whereby dispersed molecules or particles are held together by weak physical interactions ultimately leading to phase separation by the formation of precipitates of larger than colloidal size.
It is used as a flocculant that only takes a few weeks or months rather than years to degrade in the environment. Chitosan purifies water by chelation. This is the process in which binding sites along the polymer chain bind with the metal ions in the water forming chelates. Chitosan has been shown to be an excellent candidate for use in storm ...
These water-soluble polymers are used as flocculants and coagulants in solid/water separation to recycle water, rheology modifiers and friction reducers. These functionalities have many uses where water is used, in drinking water production, wastewater treatment , mining , paper , enhanced oil recovery , hydraulic fracturing , agriculture ...
Artificial polymer: Man-made polymer that is not a biopolymer. Note 1: Artificial polymer should also be used in the case of chemically modified biopolymers. Note 2: Biochemists are now capable of synthesizing copies of biopolymers that should be named Synthetic biopolymer to make a distinction with true biopolymers.
These polymer finishes are also capable of imparting a soft and smooth handle to synthetic fabric without making it water repellent. Fire-resistant or flame-retardant finish reduces flammability . Anti-microbial finish: with the increasing use of synthetic fibers for carpets and other materials in public places, anti-microbial finishes have ...
The associative complex is essential to for polymerization to occur in a living fashion since it allows the metal to undergo a preferred intramolecular oxidative addition and remain with a single propagating chain (consistent with chain-growth mechanism), as opposed to an intermolecular oxidative addition with other monomers present in the ...
Coex preserves the physical and chemical characteristics of the raw material from which it is formed. The main features of Coex materials are comfort, hydrophilicity, antistatic properties, mechanical resistance and versatility in the textile sector, like all natural and semi-synthetic cellulosic fibers.
Qiana (/ k i ˈ ɑː n ə / kee-AH-nə) [1] is a silky nylon fiber developed in 1962 at the DuPont Experimental Station by Stanley Brooke Speck. The fiber was named Qiana when introduced by DuPont in 1968. [2]
