A STORYOF SUCCESS

Specialising for over 50 years in the measurement of viscosity,rheology and texture analysis, Lamy Rheology has seen the scope ofits business gradually expand over the years.

Initially, the exclusive distributor of the Contraves brand until 1991,then of Mettler-Toledo and Rheometric Scientific, Lamy then started to design its own instruments to complement those already offered by these firms.

The entire range of Lamy Rheology rotating viscosimeters and rheometers has been developed and is manufactured in France, in our premises located near Lyon. Our instruments are sold worldwide through quality dealers.

Of course, Lamy Rheology’s expertise does not stop there: “We provide you with increasingly high-performance products, such as the new RM100i, a fully digital industrial viscometer.”

Lamy Rheology provides all its customers with a complete range ofservices:

“Our team of technicians provides you with quality after-sales service: calibration and maintenance for our entire range as well asfor the CONTRAVES, METTLER and RHEOMETRIC SCIENTIFICbrands.”

“Our application laboratory is at your disposal to provide you withefficient advice when next choosing measurement instruments.”

Please contact us regarding any requests for training sessions.

Each day, Lamy Rheology strives to meet the legitimate expectationsof customers who place their trust in us.

HIGHLIGHTS

Pt100 probeBecause we believe that a product’s viscosity is inseparable from its temperature, all our viscosimetershave a Pt100 temperature probe. It’s just not optional!

Motor + cardState-of-the-art electronics combined with a springless measurement principle, ensures a wide measurement range and excellent reliability, reduces maintenance, and does not require supportlevelling.

Bayonet couplingBecause simplicity and strength are two essentialqualities for a measurement apparatus, all our instruments have been fitted with bayonet couplings for the past 20 years.

Application laboratoryNothing can replace testing that is why our application and expertise laboratory is at your disposal to ensure our instruments meet yourneeds throughout their entire service life.

RHEOLOGY KNOWLEDGE

DYMANIC VISCOSITY η (ETA) :It is defined by the NEWTON equation:And quantify measurement of internal friction of fluid. His determination needs to apply to the fluid a Shear rate (D), and tomeasure the resistant Shear stress (τ) to this rotation.

SHEAR RATE: D (γ)is the shearing which subjected by the product in the application. Itis known for measuring geometries with small gap. It is not thespeed of rotation of the bob (in rpm !).

τ = η * D en Pa.s

τ = F / S in Pa (N / m2)

D = dV / dx in s-1

For memory :1 Pa.s = 10 Poises or1 mPa.s = 1 cPoises

Either a sheared fluid, by a laminar move (dV), between two parallelplates with a surface (S) and separate by a distance dx.

SHEAR STRESS: τ (TAU)

There is the shearing force (F), with which the sample answers to theshear rate (D), divided by the contact surface (S).

RHEOLOGY:There is the « science » of « flow ».Associated physical measurements, realised with the hand of Rheometers, enables the visualisation of the behaviour of the product in various flow , temperature andtime conditions .

RHEOGRAMS:displayed curves of the flow behaviour of a fluid.The curves τ = f(D) enables, by adapted fitting, the accessto direct related parameters with the application.

ROTATING VISCOMETER:

a - With coaxial cylindersThe fluid is sheared between two coaxial cylinders, withradius Ri and Ra and a length L, by a laminar move whichare breaking down in multi-layer with different angularspeed from 0 (for the layer in contact with the fixed cylinder)to ω0 (for the layer in contact with the rotating bob). Therelative move of layers towards others give, a shear rate Dand one Shear stress τ.By imposing ω0 and measuring M, the resisting torque tothis rotation, we calculate D and τ according:

b- With Cone-Plate:The fluid is placed between a Plate and a Cone with angle δ (< 3°).The cone, maintained to a constant speed induce a laminarshearing move. In those conditions, τ and D are constant inthe gap, according:

δ = Ra / Ri Ri / Ra > 0.92Shear stress:Trep =(1+δ2 / 2 δ2) * (M / 2πLRi2)Shear rate:Drep = ω * (1+ δ2 ) / (δ2 - 1)

Rq : The determination of D is possible only if the gap is small. (i.e. DIN / ISO 3219 Standard).

Rq : You would be vigilant on the sample volume including in thegap, because the great influence of the radius R on the τ value !

Type Newtonian Pseudo-plastic Plastic

One sample presents a plastic behaviour, when his viscositydecrease when the shear rate increase, but from one originalshear stress upper than 0, called YIELD VALUE (Tau 0), shearstress under which the product doesn’t flow. It behave like a solidbody.

One pseudo-plastic samplehas a viscosity which decreasewhen the shear rate increase:This flow behaviour is due tothe molecules form and totheir internal structure:

A sample is named newtonianwhen his viscosity stayconstant, whatever the shearrate is. Iit is not necessary todefine exactly the shear ratefor the measurement. Justthe temperature is important.

STUDY OF DIFFERENT RHEOLOGICAL BEHAVIOURS

The THIXOTROPY

One thixotropic product is a sample for which the variation ofviscosity in function of shear rate is associated to a variationtrough the time.

Owe talk about Thixotropy orRheopexy, with the condition ofREVERSIBLE Transformations:frozen or solidification.

Causes of thixotropy:

- Molecular structure - Particules mixing- « Château de cartes » with layers - Ball loose Package…
