A diagram of flocking texture. 1 fiber 2 adhesive 3 substrate. Flocking is defined as the application of fine particles to adhesive-coated surfaces, usually by the application of a high-voltage electric field. In a flocking machine the "flock" is given a negative charge whilst the substrate is earthed. Flock material flies vertically onto the ...
Flock worker's lung is an occupational lung disease caused by exposure to flock, small fibers that are glued to a backing in order to create a specific texture. People who work in flocking are at risk of inhaling small pieces of the flock fibers, which causes interstitial lung disease . [ 1 ]
Particles finer than 0.1 μm (10 −7 m) in water remain continuously in motion due to electrostatic charge (often negative) which causes them to repel each other. [citation needed] Once their electrostatic charge is neutralized by the use of a coagulant chemical, the finer particles start to collide and agglomerate (collect together) under the influence of Van der Waals forces.
Agglomeration (except in polymer science) Coagulation (except in polymer science) 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.
Fumed silica with surface area of 130 m 2 /g . Fumed silica (CAS number 7631-86-9, also 112945-52-5), also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles.
For a complete, balanced meal, blend oats with a protein source like Greek yogurt, protein powder or your favorite nut butter. If you’re on the fence about adding oats to your favorite smoothie ...
The FBE powder is placed on a “fluidization bed”. In a fluidization bed, the powder particles are suspended in a stream of air, in which the powder will “behave” like a fluid. Once the air supply is turned off, the powder will remain in its original form. The fluidized powder is sprayed onto the hot substrate using suitable spray guns.
It's a $1.4 billion US hydration powder market projected to grow 13% a year to 2.5 billion by 2029. Definitely see it as more of a compliment in addition. I actually like the move.
