Mass Loss Calorimeter

Provides an inexpensive stand-alone instrument that enables mass loss rates to be determined at any heat flux in the range of the cone calorimeter model of ISO 5660

  • Provides a unit that can be added to commercial cone calorimeters so that they can be used in oxygen-depleted low flow atmospheres
  • It is readily fitted to existing or future build oxygen depletion systems
  • It is readily converted to dynamic smoke, corrosion, and toxicity tests. 

Relationship between heat release and mass loss:

 The heat of combustion is the quantity of heat released when the unit quantity of fuel is fully oxidized. These are determined using an oxygen bomb calorimeter and are well-reported in handbooks. If all fires involved complete oxidation, then the heat released could be determined simply by weighing the sample as it burns and multiplying the mass loss by the heat of combustion. In reality, combustion does not usually proceed to complete oxidation, but the effective heat of combustion is constant for a given material when burnt at a given heat flux under constant ventilation conditions. Instruments such as the cone calorimeter and the OSU determine the effective heat of combustion. Heat release is then determined as a product of the effective heat of combustion and the mass-loss rate. Once the effective heat of combustion is known for material over a range of conditions the heat release rates can be calculated from mass loss data. The FTT mass loss calorimeter is designed for this purpose.

 

​Thermal Imaging

Electrical Resistance

Hioki Super Megaohmmeter SM-8215

The Hioki Super Megaohmmeter SM-8215 is capable of measuring volume resistance from 0.25 - 2E13 Ω. Voltage range is 50 - 1000 V DC.

The SM-8215 is paired with the SME-8350 Shielding Box and SME-8320 Weight Electrode.

The SME-8350 is used as a sample accommodation box during measurement of a high-insulation resistance samples, or inductive or capacitive samples to perform electromagnetic shielding. It is particularly useful when high insulation resistance cannot be properly measured due to effects from noise and induction hum in the measuring environment. 

The SME-8320 is a plate sample surface resistance measurement electrode consisting of the main electrode, counter electrode, and positioning jig.  This electrode enables extremely easy measurement of surface resistivity and volume resistance. The main electrode dia. is 50mm, and the ring electrode inner-dia. and outer-dia. are 70mm and 80mm respectively.

 

 

Rheological and Processing Characteristics

Haake Polylab Single Screw Extruder & HAAKE Rheomex 19/25 OS

     Specifications:

  • Screw Diameter: 19.05 mm
  • Extruder Length: L/D 20
  • Feeding: Hopper

Screw plastification is the most common method of processing plastics, rubber, food packaging, and ceramic materials. Rheomex controls data administration and communication with a master unit. Mobile measuring sensors avoid the necessity of handling heavy and hot parts. Integrated heating and cooling circuits reduce the number of plug connections. Several peripheral units, such as feeding and post-extrusion units, are computer-controllable, allowing better reproducibility and documentation. This simplifies handling in the laboratory and enables secure operation. The extruder tool enables analysis of rheological and processing characteristics of many materials.

Viscosity

Rotational Haake Viscometer 7

Viscosity is a measure of the resistance of a fluid that is being deformed by either shear stress or tensile stress. Viscosity and viscoelastic behavior of resins are very critical in composites manufacturing. Our lab is equipped with a classic rotational viscometer for a fast determination of viscosity as defined in ISO 2555 and ASTM standards. For the determination of the rheological properties of a substance, the measuring range can be changed by using a different speed or by a change of the spindle. The selection depends on the standard to be followed.
