Description£º
WESTINGAREA supplied L700713 Mechanical Stability Tester have the excellent performance displayed as:
This kind of tester can be used to test the mechanical stability of natural
rubber latex concentrate, also prevulcanized natural rubber latex concentrate.
The test method used in this tester is not necessarily suitable for lattices
or prevulcanized latex preserved with potassium hydroxide, latices from natural
source other than Hevea brasiliensis, or for compounded latex or artificial
dispersions of rubber, and it is not applicable to synthetic rubber latices.
* Test Principle:
A test portion of the latex concentrate is diluted to 55% by mass total solids
content and stirred at high speed. The time required to initiate visible
flocculation is recorded, this being regarded as a measure of the mechanical
stability.
* Determination of the end-point:
The arrival of the end-point is preceded by a marked decrease in the depth
of the vortex around the stirring shaft, accompanied by loss of turbulence
and a change in the sound of stirring action.
Two methods are permitted for the determination of the end-point.
A: Palm-of-the hand method
B:Dispersibility-in-water method
