В труде определяли свободную поверхностную энергию обеих сторон лаковых оболочек, одна из которых была изготовлена в контакте с газовой, а другая - с твердной фазой. Работу адгезии исчисляли между подкладочной нитроцеллюлозным покрытием, поверхностными химоотверди- тельными покрытиями типа Пластлак и целлюлозо-уретановыми типа Цеюр, а также между лаковым покрытием и древесиной. Установлено, что значения работы адгезии исчисленные с учетом дифференциации свободной поверхностной энергии обеих сторон лаковых покрытий лучше характеризуют взаимодействие покрытий в лаковом покрытии и покрытия и древесины, чем значения работы адгезии исчисленные исключительно на основе свободной поверхностной энергии определяемой на поверхности образованной в контакте с газовой фазой. Работа адгезии между- слоями лакового покрытия более сильная, чем работа адгезии между лаковым покрытием и древесиной.

A free surface energy of both sides of lacquer coatings, one of which was formed in the contact with gaseous and another with the solid phase is determined in the paper. The adhesion work was calculated between nitrocellulose ground and surface chemohardening coats of the Plastlak type and cellulose-urethan coats of the Celur type as well as between the lacquer coating and wood. It has been found that the adhesion work value calculated taking into consideration differentiation of the free surface energy of both sides of the lacquer coatings characterize better the interaction of coatings in the lacquer coat and coat with wood than the adhesion work values calculated exclusively on the basis of free surface energy determined for the area formed in the contact with the gaseous phase. Ihe adhesion work between lacquer coatings is higher than the adhesion work between lacquer coating and wood.

The process of simultaneous precipitation of phosphorus from synthetic wastewater in aerobic biological systems with Fe(II) and Al(III) salts has been studied. Respirometric measurements have been applied to rvaluate the influence of heavy metals on activated sludge respiration activity. The factors which influence the evaluation of inhibition or stimulation effect of precipitants on biomass have been studied. The stimulation effect of Fe on heterotrophic biomass respiration activity was observed in typical metal concentrations range applied in the chemical process of phosphorous removal. The influence of precipitants on biokinetic parameter values has been investigated. Not only phosphorus elimination and the increase of activated sludge activity, but also the improvement of sludge settlement characteristics and improved efficiency of organic impurities removal resulted from the work.
