High speed mechanical stability tester testing machinePurpose and Scope of Application

This instrument is suitable for scientific research institutions and latex manufacturers to conduct mechanical stability testing on natural latex or synthetic latex. It is an essential instrument for improving the quality of latex. This product meets the requirements of IS02006 standard for testing instruments.

High speed mechanical stability tester testing machineInstrument characteristics

The speed of the instrument is stable. When running at 14000r/min, the speed fluctuation range does not exceed 100r/min. And it can be set arbitrarily between 3000r/min and 20000r/min. This product uses a high-speed synchronous motor with high precision, smooth operation, long service life, and low noise. The speed regulation part adopts variable frequency speed regulation, which has good performance, reliable quality, and simple and accurate operation.

Main specifications and technical parameters

1. Specification of mixing tray:

a、 Natural rubber latex:

Diameter: 20.83 ± 0.03mm

Thickness: 1.57 ± 0.05mm

b、 Synthetic latex:

Diameter: 36.12 ± 0.03mm

Thickness: 1.58 ± 0.05mm

2. Latex container: height 127mm, inner diameter 58 ± 0.25mm, wall thickness 2.5mm

3. The distance between the bottom of the mixing plate and the inner surface of the bottom of the latex container is 13 ± 1mm

4. Speed range: can be set arbitrarily between 3000r/min and 20000r/min (including 14000r/min).

5. Working voltage: 220V ± 10%, current 5A.

6. Working temperature: 10-40 ℃.

7. Working medium: Synthetic latex or natural latex with a pH value between 1 and 14.

8. Working hours: Generally, the motor can work normally. When the motor runs for a long time and the temperature of a certain part of the motor rises to 60 ℃, circulating water can be introduced for cooling and continued operation.

Main structure and working principle

1. Main structure:

The instrument consists of three parts: (1) speed regulation and measurement part. The motor drives the high-speed rotating parts of the mixing shaft and disc. ⑶ Base and adjustable latex container.

Speed regulation and measurement part: frequency converter, speed display.

2. Working principle:

A high-speed motor with a long shaft and a stirring plate at the shaft end. The high-speed rotating motor drives the long shaft and the mixing plate connected to it to operate. Stirring latex in the horizontal direction with constant shear force on a metal disk. Determine the content of solidified material produced over a specified period of time.

Operation and usage

1. Select the mixing plate as needed and fasten it onto the shaft.

2. Take the required samples according to regulations and pour them into a latex container, then place the container on the rack and lock it tightly.

3. Connect the power supply (220V) and turn on the power switch.

4. Raise the latex container bracket to the circular ring on the guide column, adjust the fine-tuning knob of the container bracket to the lowest position, and extend the long axis towards the latex container, which is 13 ± 1mm from the bottom of the mixing plate to the bottom of the latex container. Lock the bracket.
