Übersetzung für "Abrasion loss" in Deutsch

The weight loss (abrasion) of the tape in milligrams is determined.

The coated catalyst is very abrasion-resistant and its abrasion loss, tested on a 100 g sample by the method described in Example 1(a), is only 0.05%, based on active material.

The abrasion loss of the finished catalyst, determined by the method described in Example 1(a), is about 0.1%, based on active material.

This feature, however, had the effect that the portions of the discs making contact with each other performed slightly different movements, resulting in the film cards being subjected to shearing forces and, as a consequence, in abrasion and loss of kinetic energy.

In addition tablets produced in this manner often have inadequate hardness and excessive abrasion loss so that high losses occur when producing film coated tablets due to breaking of the tablets in the coating pans used.

In addition the compacted forms of administration (tablets) have the necessary desired physical properties such as adequate hardness and low abrasion loss.

Masking of the plastic properties of the active substance in order to ensure a perfect compression independent of the compression force resulting in a high hardness and low abrasion loss of the compacted materials.

Subsequently the pharmaceutical masses obtained in this manner are tabletted and the hardness and the abrasion loss of the tablets obtained are determined.

The example shows that the IR form of administration according to the invention with a primary and secondary coating of the active substance does not cap and exhibits a very low abrasion loss and moreover it has a significantly increased hardness.

The problem underlying the invention is to produce aluminum oxide elements with optimum bead shape and narrow grain spectrum, in conjunction with suitable porosity and high breaking strength plus low abrasion loss.

They have a higher tear resistance and flexibility, even in the dry state and after relatively long use, and reduced abrasion loss.

The interval required to achieve suitability to withstand passage of traffic is the interval between the application of the trafficway marking and the juncture at which it becomes impossible to discern any alterations in the form of any abrasion, any loss of adhesion to the trafficway surface or to the embedded glass beads, or any deformation of the marking.

The period required to attain capability to withstand wheeled traffic is the period from the application of the trafficway marking to the juncture at which it is no longer possible to discern any alterations in the form of abrasion, of adhesion loss to the trafficway surface or to the embedded metal particles and optional glass beads, or deformation of the marking.

The example shows that there is no capping with the IR forms of administration according to the invention with a primary and secondary envelope around the active substance and they have an extremely low abrasion loss, moreover, they are considerably harder.

Abrasion is the loss of material at the surface of materials which occurs through their use or transport.

This is recommended for very abrasive products and sharp materials (abrasion loss as per NFT 46012, ISO 4649 and DIN 53516, average value 100 mm3).

In addition, a tear strength is preferred for the polyurethane used in accordance with DIN ISO 34-1Bb of between 60 and 90 N/mm, in particular between 70 and 80 N/mm, as well as an abrasion loss in accordance with DIN ISO 4649-A of between 30 and 50 mm 3, in particular between 35 and 45 mm 3, a compression set in accordance with DIN ISO 815 of between 20% and 30% at ambient and of between 35% and 55% at 70° C. Further preferably there is a tensile strength at yield between 20 and 60 MPa, in particular between 30 and 50 MPa, on storage for 21 days at 80° C. in water in accordance with DIN 53504-S2 and an elongation at break between 500% and 800%, in particular between 600 and 700%, on storage for 21 days in water in accordance with DIN 53504-S2.

This difference may also be explained through abrasion losses and losses during spraying within the various technology steps.

The abrasion leads to losses even during production of the granulated polysilicon in the fluidized bed.

A further advantage is the low abrasion losses of 65 and 59 mm3 (ISO 1183).

After this time, the untreated granular active carbon had been virtually completely converted to a powder, while sieve analyses showed that in the case of the granular active carbons coated according to the invention, as described in Examples 1 to 6, the abrasion losses were less than 2%.

These lead to the formation of coatings in dry compression vacuum pumps with small slits, resulting in abrasions, loss of clearances, and thus in greater wear phenomena.

This reaction chamber 14 has the purpose of rendering harmless any gas components which are drawn into pump 1 with the aspirated gases and which may endanger the operation of the vacuum pump, so that abrasions, losses of clearance, corrosion or the like in the pump stages 4 and 5 following the reaction chamber 14 are prevented.

This adverse property is disadvantageous for the use of such a carrier catalyst in industrial practice since abrasion, enzyme losses and reactor blockages occur under the hydrodynamic conditions which exist in the reactor.
