Definitions

  • the MMVF products are made using this apparatus by a process in which fibres are formed by pouring melt onto the top rotor while the rotors are rotating and the air blasts are being discharged and thereby forming a cloud of fibres traveling forwards from the spinner, and collecting the fibres from the cloud as a web, and if necessary converting the web to the insulation product.
  • This conversion may include cross lapping, and may include curing any binder.
  • binder in the web by spraying it on to the fibres as they are thrown off the rotors and carried forward from the rotors.
  • the primary air which provides the wall jets serves predominantly to promote fibre formation, and also to provide some transport air to carry the cloud of fibres away.
  • Various velocities have been proposed in the literature for the primary air for these purposes.
  • the improvement is manifested particularly when the insulation product has relatively low density, usually below 100kg/m 3 and generally in the range of 5 to 60kg/m 3 , preferably around 10 to 40kg/m 3 . It is surprising that it is beneficial to make these relatively low density products at these high air blast velocities. When examining the effect of air velocity on product quality we have found that, with the exception of these particular products, it is usually preferred for the lower density products to be made using primary air blast velocities well below lOOm/s and so it is surprising that the higher velocities are beneficial in these particular products .
  • a preferred additive is graphite in the form of particles, especially lamellar particles.
  • Air-laid MMVF products comprising graphite are described in our co- pending application no. PCT/EP 99/ (reference
  • the volume of secondary air on the cascade spinner is generally above 3000Nm 3 /hr, preferably above 3500 up to, for instance, 7000Nm 3 /hr, with best results generally being obtained with around 4000 to 6000Nm J /hr.
  • the impulse due to the secondary air is generally above 8 ON and usually is above 100N. It may be up to, for instance, 250 or 350N, with best results generally being obtained with values in the range 120 to 20ON. It is not essential that there should be secondary air on each (or any) of the subsequent rotors. For instance, it can be preferred to have primary air only on the first subsequent rotor and secondary air on the remaining two subsequent rotors (when the spinner consists of four rotors) . Generally the secondary air slots (and the primary air slots) extend over 1/3 to A of the periphery of each of the subsequent rotors which each is associated.
