Description
Vyplaz sa týká zariadenia na ueranie tokového aprávania viekoelastických Látok při primom a vratnou dotvarovaní v po&nLenkach jednoduchého střihu.The invention relates to a device for purifying the flow and processing of vapor-elastic substances by direct and reciprocal creep in single shear bags.
Tokové správanie niektorých Látok sa vyznačuje tým, Se v uTčitej tepLotnej obliti Leh nie je možné považovat za pravé /newtoMcké/ kvapaliny, ani za pevné telená. Leh Teologické eprávanie je kornbináciou vLskoznej a elastickej sLožky. Přikladou takýchto Látok sú bitúneny, olejové farby, niektoré polyuéry atď.The flow behavior of some substances is characterized by the fact that in a certain temperature range Leh can not be considered as true / newTechnical / liquid or solid bodies. Leh Theological narration is a combination of a viscous and elastic component. Examples of such substances are bitumen, oil paints, some polymers, etc.
Z charakteru viekoelastických Látok vyplývá, že Leh . tokové' správaMe je závislé na velkosti aplikovaného napátia a době trvania deformáde.The nature of the vio-elastic substances implies that Leh. The flow management is dependent on the magnitude of the applied stress and the duration of the deformation.
Na opísanie tokovýeh vlastností takýchto Látok nedostačuje morente viskosity, keftže tá dává málo informácií o Leh elastickej zLožke správania. Viac informáccí o charaktere toku je uožné získat z uerania prianeho a . vratného dotvarovada.In order to describe the flow properties of such substances, the morbidity of viscosity is insufficient since it gives little information about the Leh elastic component of behavior. More information about the nature of the stream can be obtained from the desire of a. vratného dotvarovada.
Pre testy dotvarovada je možno vybrat test v tahu a v střihu. Výhodneěáí je střihový test pre Lepáie vyrnsádede vzorky.For the creep tests, the tensile and shear tests can be selected. Preferably, the shear test is for the sample size.
Známe zariadenie na meranie dotvarovania viekoelastických Látok v jednoduchou střihu pracuje na nasledovnou principe.The known device for measuring creep elasticity of multi-elastic substances in a single shear works on the following principle.

Aby pri odlahčovaní závažia nevznikol ráz, ovplyvftujúci aníoacii zariedlnLl, Je odlahčovací mechanizmus vybavený hydrauliký! tloinío.The required upper body in the horizontal sook, exerted by the weight through the lever mechanism and the foil, acts on the movable frame of the upper plate. The frame is zeroed so that the foreign atred sample always passes through the aonation and thickness of the axes of the force to eliminate the bending stresses. The lower limit - the size of the applied voltage is not given - Is it possible to reduce it continuously? to zero. The entire selected voltage begins to effect on the sample at a tightly dipped time, and at any desired, desirable time, it can be immediately removed by means of a mechanism that, for example, lifts the voltage-generating pulse from the timer. In order to avoid the impact of unloading the weight, which affects the annealing of the device, the unloading mechanism is equipped with a hydraulic! tloinío.
