|The product||Bettini produces two titanium oxide types: titanium dioxide TiO2, yellow coloured, and titanium trioxide Ti2O3, an electrical conductor black coloured.|
|Properties||Low friction coefficient, good electrical conductivity for the black trioxide, good mechanical and wear resistance.|
|Applications||Thread guides for delicate yarns and for mid-high stresses with a surface to be mirror polished. It is necessary for texturizing machines.
The black one, trioxide, is suitable to dissipate electrostatic charges from yarns on various textile machines, e.g. knitting machines.
|Production processes||Extrusion; dry and isostatic pressing; injection moulding.|
|Technical data||The following table gives physical and mechanical data. Material data are obtained from specimens according to international test specifications. The indicated values can’t be extended to components and parts with different shapes and surface finishings.
Bettini S.r.l. reserves the right to make technical modifications.
Standard tolerances: up to 10mm: ± 0.2mm, above 10mm: ± 2%
Bending deformation: max. 0.5% of part length.
Very close tolerances can be reached by grinding and polishing sintered parts, normally up to quality class IT8. Few microns tolerances can be achieved if needed.
NEAR-NET SHAPE can be obtained by injection moulding reducing hard machining operations.
The sintered products are manufactured with the following surface finishings.
For delicate yarns with a medium wear value and for synthetic yarns, before texturizing titanium oxide is used with polished finishing. For synthetic yarns or continuous fibres when there is a risk of electrostatic charging, black titanium oxide is used (good electrical conductivity).
