Blocking & Picking Points Apparatus
Applies wax samples to paper test specimens and creates a temperature
gradient for determining blocking point and picking point temperatures.
Wax Coating Device – Coats paper with wax samples per ASTM
specifications. Consists of an insulated electrically heated hot wax bath and
a cooling water bath with doctor rods and paper roller. Variable auto
transformer and 200W heater situated underneath the hot wax bath heat sample
to a temperature above the melting point. Doctor rods connect to an external
hot water supply to maintain proper temperature. Cooling bath has water
inlet/outlet fittings, and each bath has a built-in paper guide.
Blocking Plates – Choice of Type A or Type B plates per ASTM
specifications. Type A Aluminum Blocking Plate uses a strip heater and
cooling coil on opposite ends of the block to create a temperature gradient.
Six thermocouples along the length of the block input to accessory Digital
Thermometer. Accommodates eight rows of paper test specimens. Type B Aluminum
Blocking Plate uses two thermostatically controlled baths to establish a temperature
gradient, with the ends of the plate extending into the baths. Cold bath has
a cooling coil and 100W immersion heater; hot bath has a 300W immersion
heater. Thermoregulators and motor stirrers provide uniform temperature
control in each bath. Ten thermocouples along the length of the block input
to accessory Digital Thermometer. Accommodates six rows of test specimens.
Digital Thermometer – Ten-channel microprocessor based digital
thermocouple thermometer with large LED display. Ten-position front panel
rotary selector switch. Mounted in a heavy duty bench case.
