The Viscosity Measurement System is a specialized and automated testing equipment designed for measuring the intrinsic viscosity, viscosity number, average polymerization degree, and viscosity average molecular weight of polymers. Depending on the number of test units configured in the system, it is categorized as NCY-X/2, NCY-X/4, and NCY-X/6, with corresponding configurations of two, four, and six test units, respectively. These setups can simultaneously support the use of two, four, or six viscometers.

UtilizeNcy-xViscosity Automatic Measurement System Ahead:

The measurement of the time required for a certain amount of solution to flow through a capillary, originally performed manually.

Originally, the determination of the validity of data was performed manually.

Just like the NCY Automatic Viscosity Meter, it will still be executed by the system.

The system will still display the flow of the solution in the capillary viscometers of each unit in real-time and visually.

The system will still automatically retest and eliminate results that exceed the specifications, ensuring accurate flow time.

The system still features the JWC precision temperature-controlled槽, a result of our 1990s national research project, and continues to consistently deliver temperature fluctuations and distribution within ±0.01℃ over extended periods, ensuring the consistency of test data at any moment and location.

In addition, the automated testing system will feature the following new functions:

Automated liquid dispenser with a precision of up to 0.1% concentration, capable of conveniently preparing sample solutions (one-button dispensing).

Double-glazed isolation design of the dissolution bottle ensures that the prepared solution dissolves quickly and evenly in the precise temperature oscillating bath without interference from moisture.

Automated Liquid Delivery System, eliminating the need for manual feeding into the viscosity tube; a comprehensive device that automatically filters the solution and delivers it into the capillary of the viscometer.

Automatic test completed; the system will automatically extract waste fluid and wait for the arrival of the next sample to automatically complete the capillary rinsing and testing.

When cleaning capillaries is required, simply activate the cleaning program, and the system will autonomously complete the entire process of fluid injection—immersion—recycling—cleaning—drying, without the need for manual intervention.

System Structure

Ncy-xThe Automatic Viscosity Measurement System consists of the following components:

1.1 The NCY testing unit, equipped with a variety of sensors and paired with a central controller, can perform tests and also clean the capillary viscometer within the unit.

1.2 JWC series precision thermostatic baths for placement of test units, ensuring the unit operates within a normal working environment temperature (instruction manual included).

1.3 PY Series Automatic Mixture Instrument (optional, manual included).

1.4 WR-2 Rapid Sample Solvent Constant Temperature Oscillator (optional, manual included), equipped with a set of double sample bottles, operates at precise temperatures while effectively preventing moisture interference during operation.

1.5 NCY-X Viscosity Automatic Measuring System, included in the central control system, achieves an accurate measurement of the time taken for the solution to flow through the capillary.

Sampler 1.6

Samples are dissolved in the solvent bottle and placed here. After the system initiates testing, the required solution will be automatically filtered through a sand core and sent to the capillary.

1.7 Washing System

Pre-set various detergents for cleaning, under the cleaning program for a specific unit in the central system, clean the viscometer, filter, and all fluid lines used during the automatic testing. After cleaning, dry the unit.

1.8 Commercial or industrial computers with a printer, keyboard, and monitor, etc., as terminal equipment.

1.9 NCY-X Automatic Viscosity Test System Central Controller

2. Layout of the Automatic Viscosity Measurement System

This automatic testing system is composed of several components, which can be arranged in various configurations according to the user's arrangement, but its fundamental principle is:

2.1 Ensure all pipe distances are as short as possible, while also considering actual operations such as filling and pouring. The cover image illustrates a typical reasonable layout.

2.2 The pipeline from the central control unit to the viscometer must start from the central control system and gradually decrease, with no rise in the middle.

3. Sample Handling

3.1 Automatic Solution Preparation

See PY Automatic Mixture Dispenser manual (optional accessories).

3.2 Rapid Solubility of Sample

Please refer to the WR-2 Rapid Sample Dissolution Oscillator manual (optional accessory), featuring a sample dissolution bottle with a double-layered insulating sleeve.

The dissolution process of the sample in the solvent can sometimes be very lengthy, taking up to one, or even more, hours. It requires shaking at as high a temperature as possible to accelerate the process, but excessive heat will lead to degradation, so the temperature needs to be precisely controlled.

4. Vacuum Pressure Adjustment

The automatic testing system operates under the influence of vacuum pressure. This system is equipped with different pressure sources specifically for the injection, testing, transmission of cleaning fluid, and drying. Different vacuum pressures need to be adjusted according to the solvent composition of the sample and cleaning fluid.

Vacuum Pressure Adjustment Method:

There are two pressure gauges on the central control system panel: one for adjusting and controlling the working pressure of the sample solution with a constant pressure gauge, and the other for adjusting and controlling the working pressure of the washing liquid with a pump pressure gauge.

Vacuum pressure adjustment methods are as follows:

Press the pattern key (left button), until it shows L0-2 shows the lower limit of the current vacuum setting. Press the up and down keys to adjust the upper limit setting.

Press the mode key again to display H1After -2, the current upper limit of vacuum degree is displayed. Press the up and down keys to change the upper limit setting.

Note: The vacuum pressure value is negative.

5. Inlet and Testing

Prepare a clean empty solvent sample bottle, remove the solvent bottle containing the dissolved sample from the oscillator, pour half of its contents into the empty solvent bottle, and place them together in the corresponding sampling unit position.

During testing, approximately 13mL of sample is required. Therefore, if rinsing is needed prior to testing, approximately 26mL of solution must be prepared. Place the dissolution vessel on the autosampler, press the rinse button for the corresponding unit, and the dissolution vessel holder advances. Stop when the previous dissolution vessel (for rinsing) is at the syringe position. Lower the syringe and insert it into the volumetric flask. At the same time, the volumetric flask for testing is automatically sealed. After initiating the test, the testing system will automatically draw the solution from the dissolution vessel, complete the rinse, and automatically discharge the liquid.

Keep holding the test button, another sample vial is sent to the testing station, wait for the test to start. Test completed, the sample vial returns to the starting position.

Sample bottle location

Wash position: The liquid suction tube is inserted into a solvent bottle in front, and the mouth of the solvent bottle behind automatically covers.

Test Port: Insert the liquid tube into the vial at the back.

Test completed, solvent bottle returned to starting position.

After launching the test program for this unit on the computer, the unit automatically enters the working state. The subsequent operations are performed automatically by the system. The operator can view the progress of the unit's testing on the screen, and a dialog box will automatically pop up if an issue is encountered during the test.

Test complete; the system automatically discharges waste after which it proceeds to the next test phase.

6. Capillary Viscometer Cleaning and Drying

Viscometer should be cleaned after being used for a period of time.

First, place a solvent sample bottle in the rinse position (it can also be the test position) of the sampler, and the pipette will automatically insert into the bottom of the bottle (this is very important!!)

Check and ensure there is an adequate supply of solvents like detergents and clean water, as well as sufficient remaining space in containers for waste liquids and wastewater.

Then you can initiate and complete the full cleaning-drying process.

Select "Wash Solution Soaking" on the computer interface, and the viscometer can complete the entire cleaning-drying process.

7. Routine Maintenance

7.1 Liquid Storage Bottle

The storage bottle requires regular monitoring of the liquid level. For waste liquid collection, timely cleaning is necessary when the level is high; for new liquid, timely replenishment is required.

When removing the bottle cap, pay attention to the original installation. Some may come with a layer of Teflon film, which is for the corrosion issue of the cap. When reinserting the plastic tube, be sure to note the tube's number, as well as the corresponding entrance indicated on the bottle label. When replacing the cap, make sure to tighten it properly and ensure a seal.

7.2 Vacuum Pump

This type of vacuum pump, when in use, if the suction inlet maintains vacuum (low pressure), it may cause the oil pump to spray oil outward from the suction inlet. The machine has been equipped with a special program in the control system to prevent oil spraying. However, after a considerable period of use, the oil level will also decrease. When the oil level in the pump side's oil gauge falls below the "min" mark, oil should be added to the vacuum pump from the suction inlet until it reaches between the first and second graduation lines on the oil gauge.
