DH-900B Carbon black content tester for polyethylene, polypropylene
and polybutene plastics.
Summary:
With the alarm function at the end of the experiment, the alarm
time can be set and the ventilation time of nitrogen and oxygen can
be set. The instrument can automatically switch the gas without
manual waiting for the switch
Application: suitable for the determination of carbon black in
polyethylene, polypropylene and polybutene plastics.
Technical features:
1. 7 inches wide touch screen control, current temperature, setting
temperature, decomposition state, pyrolysis state, constant
temperature state, air pipe calcining, operation time, oxygen
filling state, nitrogen filling state and other information
integration display, operation is very simple.
2. Heating furnace body and control system integration design,
convenient for user's instrument management.
3. The pyrolysis, decomposition and air pipe calcining temperature
program section is automatically stored. The user only needs to
start the operation with a button, which saves tedious repeated
temperature setting. Fully automatic operation control in the real
sense.
4. Nitrogen and oxygen gas instrument automatic switching, equipped
with high-precision floating ball gas flowmeter.
5. Rapid cooling device is selected to realize rapid cooling of
temperature and improve the utilization efficiency of the machine.
6. Double door knob furnace door design, convenient for users to
take and charge the material.
7. Nano blanket new insulation material, achieve excellent thermal
insulation effect, high uniformity of furnace temperature.
8. Conform but not limited to the following criteria: GB/T 13021,
JTG E50 T1165, IEC 60811-4-1, ISO 6964.
