The dissolution of plastic grains in volatile solvents
suffered with constant reduction of the solvent amount due to its evaporation .Further, if the plastic grains are of different sizes their dissolving time varies which may affect the properties of the end product.
Helium users in the present sample evidenced sociodemographic, psychological, and psychiatric characteristics similar to those of adolescent users of volatile solvent
inhalants (e.g., Howard et al.
users can be classified as either experimental, recreational, or habitual (Langa, 1993).
* Volatile solvents
-- butane, gas, goop (a product used to resole shoes), paint, kerosene, gun cleaning solvents, nail polish and nail polish remover, rubber cement, paint thinner, model glue, varnish, toxic markers, lighter fluid and propane.
By substituting supercritical carbon dioxide for much of the volatile solvents
in conventional low-solids and high-solids topcoats and sealers, the system reportedly can reduce VOCs by as much as 50 to 80 percent.
The choice of volatile solvent
is very limited because most of known volatile solvents
for polymers are not miscible with water.
All youth completed the Volatile Solvent
Screening Inventory (VSSI), an interview developed by Howard and colleagues (2008) assessing demographic characteristics, medical history, lifetime/annual use of 65 inhalants, other drug use and substance-related problems, current psychiatric symptoms, thoughts of suicide/actual suicide attempts, trauma history, antisocial traits and delinquent behavior.
It also contains a gel-promoting solvent, film former, volatile solvent
capable of solubilizing the film former; and colorant.
One alternative solution, which is currently researched at the Institute of Applied Medical Engineering (AME), is to dissolve the polymer in a volatile solvent
and then alomize the solution in a commercial spray nozzle, without using any electrical field.
In addition, there were said to be growing HMIS concerns regarding volatile solvent
emissions, and the problem of storing flammable material.
Latest figures reveal Scotland has the highest death rate from volatile solvent
abuse - VSA - in the UK.
where c is the molar concentration of the volatile solvent
in the liquid.
