Description
The utility model relates to a kind of macromolecular material proving installation, particularly a kind of viscosity test device of hard resin high-temperature fusant.
Viscosity test device commonly used has: capillary tube technique, rotary process, vibration container method.Capillary tube technique and proving installation thereof are usually used in normal temperature, measuring accuracy height, but the easy measured sample obstruction of kapillary, and the viscosity that is used in test hard resin melt is equally easily stopped up kapillary by melt, and easy cleaning does not influence measuring accuracy.Vibration container method and matching requirements measurement environment thereof are vacuum, are mainly used in liquid metal, measuring error is big.Rotary process and device comparative maturity thereof, applied range, its method has: garden tube method, awl/plate method, bipyramid method etc., but the domestic report of not seeing the proving installation that is useful on the test viscosity of high-temperature melt as yet.Be used to test the particularly proving installation awl/plate method commonly used of the melt viscosity of hard resin of high-temperature fusant abroad, but cost an arm and a leg, 6000～8000 dollars of every covering device need, and easy cleaning not, temperature fluctuation is big, and accuracy of detection is low.Document is learnt by retrieval, the relatively more approaching following patent report that has of the present utility model: " a kind of proving installation that is used to measure viscosity of high-temperature melt " (the ZL patent No. 94228076.8), be mainly used in metallurgical test, accuracy in detection is higher, but because of the melt viscosity temperature influence of hard resin very big, and this device is not provided with the constant-temperature temperature-control device, can not satisfy the requirement of measuring the hard resin melt viscosity.The another kind of device " mariages rocks the method proving installation " (the ZL patent No. 94207420.3) of measuring viscosity of high-temperature melt, it disposes platinum sampling receptacle and platinum probe, costs an arm and a leg, and when being used to measure hard resin, measuring vessel is easy cleaning not, must soak with strong base solution high temperature.Garden tube method rotational viscosimeter is arranged at home, and routine NDJ-79 type is widely used, but is usually used in the measurement of normal temperature liquid, and it does not have configuration to be used to test the heating and temperature controlling device of high-temperature fusant such as hard resin melt viscosity yet.
The purpose of this utility model provides a kind of proving installation that the heating temperature-controlling system is applicable to test hard resin melt viscosity that is provided with.
The utility model is to reequip on the basis of NDJ-79 type rotational viscosimeter, has increased high temperature heating system, temperature-controlling system and heating power supply system.The utility model includes: reduction carrier (1), shaft coupling (2), left-handed knurled nut (3), rotating cylinder inner spring (4), sensor (5), rotating cylinder (6), the container (7) of containing tested melt, thermometer (8), test cup (10), heating system (11), heating system binding post (12), instrument carriage (13), nut collar (14), test cup nut (15), heating power supply system (16), temperature-controlling system (20).The high temperature heating system is one and is attached to the outer heating jacket of test cup that heating jacket has six layers, is stainless steel layer, mica splittings, resistance wire layer, mica splittings, stainless steel layer, heat insulation layer from the inside to surface successively.Resistance wire is received binding post, and system is connected with temperature-controlled power.Temperature-controlling system is a temperature controller, and the control temperature fluctuates fluctuation range ± 1 ℃ about measured value (as 200 ℃).Contain conduction oil in the test cup during energising test, transfer heat to the container of containing tested melt, make melt remain on certain molten condition, adopt garden tube method test melt viscosity again by conduction oil.
The utility model has the advantages that apparatus cost is low, the measuring accuracy height, easy for operation, the container easy cleaning is without organic solvent and alkali lye, can in short-term or carry out the test of multiple hard resin continuously, owing to installed high temperature heating system and temperature-controlling system additional, Range of measuring temp big (normal temperature-250 ℃), programming rate is fast, homogeneous heating has satisfied the requirement of test hard resin viscosity of high-temperature melt.
