Изобретение относитс к исследоза}1ию полиэфирных лаков, примен емых, в частностп, в мебельной нромышленности.The invention relates to a étransmitter of polyester lacquers, used, in particular, in the furniture industry.
Известен способ определени внутренних напр жений в лаковых покрыти х, который заключаетс в том, что на подложку, состо щую из трех трубок, вставленных друг в друга и скренленных между собой, нанос т покрытие, на которое наклеивают тензодатчики, а затем производ т поочередное отсоединение внутренних трубок, начина с центральной, вследствие чего тензодатчики регистрируют деформацию покрыти , котора мен етс в зависилюсти от жесткости подложки 1.There is a known method for determining internal stresses in lacquer coatings, which consists in applying a coating to a substrate consisting of three tubes inserted into each other and skranded among themselves, onto which the strain gauges are glued and then alternately disconnected the inner tubes, starting with the central ones, as a result of which the strain sensors register the deformation of the coating, which varies depending on the rigidity of the substrate 1.
Наиболее близким к описываемому вл етс способ определени внутренних нанр жений в лаковых покрыти х путем нанесени покрыти па плоскую, консольно защемленную подложку, но прогибу незащемленного конца которой определ ют усилие усадки покрыти 2.The closest to the described method is the method of determining internal stress in lacquer coatings by applying a coating to a flat, cantilever-supported substrate, but the deflection force of the coating 2 is determined by the deflection of the non-clamped end.
Недостатком известных способов вл етс то, что покрытие при формировании претерпевает некоторую усадку, в результате чего мен етс характер релаксационных процессов и Biiyrpei-iHHx ианр;1жений в покрытии, который отличаетс от напр жений, возникающих на недеформируемой подложке.A disadvantage of the known methods is that the coating undergoes some shrinkage during the formation, as a result of which the nature of the relaxation processes changes and the Biiyrpei-iHHx pattern changes in the coating, which differs from the stresses on the non-deformable substrate.
С целью повыщени точности измерени путем сохранени иервоначального размера ла2In order to improve measurement accuracy by maintaining the original size of la2
кового покрытн по предлагаемому способу используют составную подложку, включающую две крайние части, одна из которых неподвижна , и среднюю часть, не имеющуюCovered by the proposed method using a composite substrate, comprising two extreme parts, one of which is fixed, and the middle part, not having
адгезии к покрытию и служащую временной опорой в период напесепи лака.adhesion to the coating and serving as a temporary support during napesepi varnish.
На чертеже пзображепо устройство, реализующее оннсываемый снособ.In the drawing, a device that implements an onsable pull.
Неподвижна 1 и подвижна 2 части иодложки устанавливают в фиксирующую рамку 3. Между част ми подложкп располагаетс съемный вкладыш 4, а сверху него с некоторым перекрытием ширппы промежутка иакладываетс средн часть 5 подложки,The stationary 1 and the movable 2 parts of the i-cover are installed in the fixing frame 3. A removable insert 4 is disposed between the parts of the substrate, and the middle part 5 of the substrate is laid on top of it with some overlap of the spirits
имеюща слабую адгезию к испытуемому покрытию 6.having poor adhesion to the test coating 6.
Вкладыщ 4 устанавливаетс по высоте заподлпцо с обепми част мп I. 2 составной подложки .The liner 4 is installed in a height zip-up with an integral part of I. 2 composite substrates.
После начального затвердевани (желаптннизацпи ) вкладыш 4 вынимаетс , а средн часть подложки удал етс . В этот момент производитс установка датчика 7, св заниого с помощью т ги 8сиодвижной частью 2 подложки , в пулевое иоложенне.After the initial solidification (gelation), the insert 4 is removed, and the middle part of the substrate is removed. At this moment, the sensor 7, which is lowered by means of the 8-motion-moving part 2 of the substrate, is installed in the bullet arm and is installed.
По предлагаемому епособу покрытие нанос т на составную подложку, средп съемна часть которой не 1меет адгезии к покрытию в отличие от крайппх участков, играющихAccording to the proposed method, the coating is applied on a composite substrate, the removable part of which does not adhere to the coating in contrast to the edge areas that play
