System Description
Some of the factors affecting the drawdown are the
shear rate and the pressure placed on the applica-
tor tool. The byko-drive employs a precise speed
control along with a consistent weight to suit the
particular material being applied.
The byko-drive is compatible with most applicators,
both bar and wire types. The applicator is placed in
front of the Pushbar so that the applicator is pushed
along the test surface once the byko-drive is star-
ted. With both the speed and weight controlled, a
consistent and uniform film is produced.
The byko-drive is equipped with either a vacuum
plate or a glass plate with clamp. The vacuum plate
uses an external vacuum source to hold a test sam-
ple in place. The glass plate model uses a spring-
loaded clamp to hold the sample.
There are two application speeds available, 1 inch/
sec (25 mm/sec) and 10mm/sec. The micro-cont-
roller electronics of the byko-drive ensures accurate
speed control under all operating conditions.
The start and stop positions of the carriage may
be modified by the operator to speed repetitive
drawdowns that use smaller sizes test samples.
