Applications dust control agents

Berger-PreiK et al. (1997) applied different pest control agents for professional use in a model house. The concentrations of active substances were monitored in the gas phase, on suspended particles, on house dust and on furniture surfaces over a period of 24 months. 2 gg/m3 and 40 pg/m3 of permethrin and deltamethrin respectively were detected on suspended particles immediately after the application while in the house dust, the initial concentrations of permethrin and deltamethrin were 50mg/kg and 150-800 mg/kg, respectively. 

Additional large-volume uses of lignosulfonates include animal feed pellet binders, dispersants for gypsum board manufacture, thinners/fluid loss control agents for drilling muds, dispersants/grinding aids for cement manufacture, and in dust control applications, particularly road dust abatement. 

Derivatives of EMA resins are useful in both the oil field and as additives for fuel oils or lubricants. As additives for oil well drilling muds, the derivatives help reduce water loss due to filtration and perform as viscosity control agents. Long-chain alkyl amine derivatives are useful as antistatic additives for fuel oils. Antistatic coatings are also readily available for many other applications. Aqueous solutions of EMA resins are claimed to be useful in foam systems for dust control. For example, aqueous solutions of the resins can be used to trap 90-95% of the airborne dust generated in a coal cutting laboratory. ... 

The successful employment of any insecticide depends on its proper formulation into a preparation that can be applied for insect control with safety to the applicator, animals, and plants. Insecticides are commonly formulated as dusts, water dispersions, emulsions, and solutions. The preparation and use of such formulations involves accessory agents such as dust carriers, solvents, emulsifiers, wetting and dispersing agents, stickers, and deodorants or masking agents (1). 

Carbaryl is effective as both a contact and an ingested agent and is one of the most widely used broad-spectrum insecticides. Uses include control of a wide variety of pests on field crops, fruits, vegetables, nuts, ornamentals, turf, lawns, and domestic animals in agricultural, commercial, and residential environments. Liquid broadcast applications to residential lawns in the United States are to be voluntarily canceled, however. Formulations include dusts, wettable powders, granules, oils, aqueous suspensions, and baits. 

Once the metal surface has been adequately cleaned of oxide contamination, dusted off and once more degreased, it is vital that the application of a bonding agent primer coat be carried out as quickly as possible to ensure that the re-oxidation of the metal surface is kept to a minimum. Ambient temperature, humidity and dust must all be controlled if the optimum bond strength is to be achieved. To consistently ensure optimum bond quality, metal components, whether unprimed or primed, should be kept in enclosed cabinets. At no time should cleaned and degreased metals be handled with bare hands. Human skin, however clean it may appear, always carries a surface layer of oils and fats, which are bond killers. Neither should metals, whether in the just cleaned state, or...
