Abstract
Изобретение относитс к измерительной технике и может быть использовано дл определени масл ных загр знений поверг хностей издели при эмалировании, гальванизации и окраски в водной среде. Целью изобретени вл етс повышение точности и производительности определени площади масл ных загр знений за счет смачивани конденсацией поверхности тела. При определении площади масл ных загр знений изделие охлаждают, а затем в течение 10-300 с выдерживают в воздушной среде с влажностью 60-80% и с температурой на 1-10°С выше температуры издели . Измер ют загр зненную маслом площадь поверхности , непокрытую конденсатом.The invention relates to a measurement technique and can be used to determine oil contaminations of the surface properties of an enamelling, galvanizing and painting in an aqueous medium. The aim of the invention is to improve the accuracy and productivity of the determination of the area of oily contaminants by wetting the body surface with condensation. When determining the area of oil pollution, the product is cooled, and then kept for 10-300 s in air with a humidity of 60-80% and with a temperature of 1-10 ° C above the temperature of the product. The surface area contaminated with oil is uncoated with condensate.

Изобретение относитс к измерительной технике и может быть использовано дл определени площади масл ных загр знений поверхностей изделий при эмалировании , гальванизации и окраске в водной среде.The invention relates to a measuring technique and can be used to determine the area of oil contamination of the surfaces of products during enamelling, galvanizing and painting in the aquatic environment.
Целью изобретени вл етс повышение точности и производительности определени площади масл ных загр знений.The aim of the invention is to improve the accuracy and productivity of determining the area of oil contaminants.
Способ осуществл ют следующим образом .The method is carried out as follows.
Подлежащее контролю изделие охлаждают , а затем в течение 10-300 с выдерживают в воздушной среде с влажностью 60-80% и с температурой на 1-10°С выше температуры издели . При этом вод ной пар конденсируетс на незагр зненной маслом поверхности в виде жидкости или льда, а замасленна поверхность остаетс сухой, если концентраци масл ных загр знений находитс в пределах 1 -104-1 105мг/г . С помощью планиметра или другого измерител The product to be controlled is cooled, and then kept for 10-300 s in air with a humidity of 60-80% and with a temperature of 1-10 ° C above the temperature of the product. At the same time, water vapor is condensed on an oil-free surface in the form of a liquid or ice, and the oily surface remains dry if the concentration of oil contaminants is in the range of 1-104-1 105 mg / g. Using a planimeter or other gauge
измер ют площадь поверхности издели , непокрытую конденсатом, по которой суд т о площади масл ных загр знений.the surface area of the product, uncovered with condensate, is measured, by which the area of oily contaminants is judged.
