Description
Technical Field
The utility model relates to a measure device of inorganic powder oil absorption belongs to inorganic non-metallic powder technical field.
Background
Oil absorption, generally refers to the minimum amount of linseed oil required to achieve complete wetting for 100g of filler. There are many factors that affect the oil absorption, such as the compactness of the powder structure, the surface morphology and fineness of the powder, the particle morphology and specific gravity of the powder, etc.
In the production of plastics, the oil absorption has important guiding significance for the selection of powder. The oil absorption is too high, the needed resin amount is high, the viscosity of the system is increased, and the rheological property of the plastic is affected seriously, so that the performance is damaged; in the paint, the powder oil absorption is closely related to the volume concentration (PVC) of the pigment and the resin, so the powder oil absorption is an important factor influencing the cost and the performance of the paint.
The traditional measurement of oil absorption is manually operated, and the mixing is not uniform; the end point is also determined by naked eyes, and the same sample is measured by different people to possibly obtain the result that the numerical values are greatly different.
Disclosure of Invention
The utility model aims at providing a solve the problem that traditional powder oil absorption survey exists, disclose a device of measuring inorganic powder oil absorption.
Realize the technical scheme of the utility model as follows, a measure device of inorganic powder oil absorption, including greenhouse banburying storehouse, high accuracy hardness tester, peristaltic pump and control terminal. The peristaltic pump is arranged in the middle of the upper part of the greenhouse mixing bin; the high-precision hardness tester is arranged at a test port at the bottom of the greenhouse mixing bin; the control terminal is arranged outside the greenhouse mixing bin and connected with the high-precision hardness tester and the peristaltic pump.
The banburying bin is a small kneader, two S-shaped roll shafts are arranged in the banburying bin, materials on two sides can be rolled up from two sides to the middle of the two roll shafts and then pressed down by the roll shafts during operation, and the materials are cut between the two roll shafts and then return to two sides of the banburying bin from the bottom of the banburying bin.
The external wall of the banburying bin is provided with a jacket which is externally connected with a constant temperature water bath or an oil bath to reach the required working temperature.
And a high-precision hardness detection probe is arranged at the bottom of the banburying bin. When the materials are extruded at the bottom of the mixing bin at a certain time, the roll shaft stops rotating, the probe pops out for a certain distance, and the deformation of the parts due to pressure is used for measurement.
The utility model discloses the theory of operation of device as follows: before testing, the hardness of the powder is measured by a high-precision hardness detector when the powder is completely wetted. During measurement, a certain amount of powder is added into a constant-temperature mixing bin, a peristaltic pump is operated through a control terminal to pump a certain amount of linseed oil into the mixing bin after the constant-temperature mixing bin is covered, the mixing bin is started, meanwhile, a small amount of quantitative linseed oil is pumped into the mixing bin intermittently through the peristaltic pump, a high-precision hardness detector detects the hardness of materials in the mixing bin regularly through a high-precision hardness detection probe arranged at the bottom of the mixing bin until the hardness of the powder in a moistening state is reached, and the oil absorption amount of the powder is calculated according to the amount of the added powder and the amount of the consumed linseed oil.
The beneficial effects of the utility model are that, the utility model discloses utilize the mode of banburying, mix powder and linseed oil, measure the hardness of adding powder behind the linseed oil through high accuracy hardness detector, measure this type of powder hardness when wetting completely with the past and carry out the comparison, obtain inorganic powder oil absorption. The device is simple and convenient, and the measurement is accurate.
