Brushing method

The brush method here the substances to be separated give a colour test with a reagent. The developed column is extruded from the tube and streaked lengthwise with a brush dipped in the test reagent the colours... 

In two studies the cleansing and irritancy behavior of surfactants [106,107] were examined. An automated skin brushing method using a specific test soil and an epicutaneous irritation test on the dorsum of volunteers were applied. A sodium sulfosuccinate monoester based on a fatty alcohol ethoxylate gave very favorable results with respect to skin mildness although this concurred with low detergency.

With this background several measuring methods are currently being discussed in the automotive and paint industry with the objective to obtain a clear characterization of the scratch resistance of clearcoats. Especially procedures that create a single scratch have recently been developed (micro or nano scratch method) [1-8], These methods are different from more practically oriented procedures that are based on relatively simple methods to fly to test or even come close to reality (e.g. car wash brush method). 

It is possible to mechanize brush methods by using hollow brushes through which the liquid adhesive is fed. This improves production rates and coating uniformity and cuts waste. Uniform films are generally difficult to achieve, but operators can become proficient with time. 

In general, zinc chloride is not considered as satisfactory for farm timbers ap coal-tar creosote, but there may be cases where its use iB advisable. For wood to be used indoors it may in some cases be satisfactory where creosote would be objectionable on account of its odor, color, etc. It is not recommended, however, for use by the brush method. 

Crude oil is.not sufficiently poisonous for a wood preservative. If the wood can be thoroughly saturated with it, water may be kept out and decay prevented but it is very difficult, if not impossible, to get enough oil into most woods by processes which are practicable on the farm. For treating by the brush method crude oil is entirely unsatisfactorily. 

In 1978, using two different iodophor formulations or a plain soap followed by an alcohol foam, Galle et al. demonstrated that one hour after scrubbing a shorter, no-brush scrub procedure with any of the antiseptics used was as effective in reducing bacterial populations on the hands as was performance of a longer, standard, two-brush method [10]. These authors went on to conclude that the reduced scrub time would allow substantial financial savings to be realized, as well as reduce the likelihood of skin trauma and dermatitis. 

Air spray is a process for spraying fine paint particles atomized by compressed air. Drying rates are high and a uniform and decorative surface is obtained. This method is used with paints that are not suitable for brushing methods, for mass produced painted products, or for products where surface appearance is important. 

The MEA with CNT-based electrocatalysts are usually prepared by using the conventional process of pasting mixed eatalysts supported on CNTs and Nafion solution onto a gas diflusion layer [63, 71, 81, 187, 188], The method eonsists of, first, preparation of flie eatalyst ink by ultrasonieating appropriate amounts of Pt supported on CNTs, Nafion solution and isopropyl aleohol [188]. The slurry was then eoated on the gas diflusion layer by the brush method and dried at 80 °C. The... 

Phosphoric acid-doped polybenzimidazole (PA-PBl) membrane is the most common type for HT-PEMFCs. It was also introduced in the catalyst layer as an ionomer to improve proton conductivity [8, 80-83]. Similar to die apphcation of Nafion ionomer in the catalyst layer, polybenzimidazole (PBl) solution was incorporated into the catalyst layer by an impregnation method (die electrode was soaked in a PBI solution), by a gluing method (the PBl membrane was coated by PBI solution), or by a brushing method (the PBl solution was brushed onto the electrode) [80].
