• Reaction: none

Application :

Viebeam Slip SP powder can be added directly to the drum, alternatively it can be made up into a slurry by diluting with water and then applying to the process vessel in the normal manner. When applied as a slurry, we recommend that it is made up and applied immediately and not allowed to stand.
We recommend that small additions of the product are added at each process stage as its effectiveness is reduced by washing off.
When used on heavy vegetable tanned leathers the improved movement within the process vessel may lead to reduction in the mechanical action and hence a slightly lower rate of tan penetration. For this application we recommend that the product is added 1 or 2 hours after the first addition of the main vegetable tannins.

Viebeam AWC – Liming auxiliary to control swelling and reduce wrinkles

Application:
Viebeam AWC is a synergistic blend of Hydrogenated Mono Saccharides, Carbamimidic acid and Amines. Hydrogenated Mono Saccharides cause the increase in osmotic pressure which leads to the accumulation of osmoprotectants in the collagen fibres, which stabilize the native protein structure and increases the production of soluble proteins. Carbamimidic acid helps solubilization and denaturation of undesirable proteins increasing overall softness, and helps percutaneous absorption of other chemicals. Yield is dramatically increased and wrinkles are reduced and also fats are broken down. Increase of yield of 3 – 5% has been experienced. The Amines smooth out wrinkles and reduce unwanted Beamhouse smells

The main characteristics are:

• Reduces Swelling, Smooths Out Fat Wrinkles, And Increases Yield

• Helps To Give A Cleaner Looking Hide, Reduces Pigmentation

• Increases Solubilization Of Undesirable Proteins Increasing Overall Softness

• Gives A Finer And Smoother Grain

The reduced swelling effect helps to give a smooth, fine grain on the leathers. Although the product does not possess an unhairing effect, the reduction in swelling does enhance the effect of the sulphides, giving a more effective removal of hair root / scud from the grain.

EXAMPLE APPLICATIONS:

• All types of Leathers, 1 to 1.5 % based on the wet salted weight

Viebeam CO – Bleaching agent

APPLICATION: BLEACHING/PICKLING

Viebeam CO is used as a bleaching agent on hides, skins or pelts. When used in the pickle, it bleaches any remaining hair root pigments giving a clean pelt. It is particularly recommended for use in the production of full aniline, white bleached and pastel coloured leathers.

The main characteristics are:

• Strong Bleaching Action

• Promotes Cleaner Pelts

• Improves Dye Levelness And Brilliance

• Minimal Effect Upon Leather Strength And Structure

PROPERTIES:

• Appearance: pale greenish yellow liquid

• Chemical character: chlorine containing oxidising agent

• Active substance: approx. 30 %

• pH value: 13.0 – 14.0

• Storage stability: min. 1 year under cool, dry conditions when stored in original, sealed packaging. At temperatures below +5 °C some crystallization and deposition on the container bottom may occur.

• Reaction: Viebeam CO has a strongly alkaline reaction and must not be directly mixed with acids, reducing agents or highly flammable substances acids – chlorine dioxide gas is released with the risk of explosion reducing agents – risk of rapid, exothermic decomposition highly flammable substances – risk of fire and explosion

APPLICATION:

Viebeam CO should be diluted with water before addition of the process vessel. As with all oxidising agents, certain precautions must be observed with Viebeam CO. In an acid medium, Viebeam CO releases chlorine dioxide gas, the active oxidising agent. For this reason, the undiluted product should not be brought into contact with concentrated acids or reducing substances. This can result in spontaneous evolution of gas, sometimes accompanied by ignition. Viebeam CO should therefore be mixed only in diluted form with diluted acids. Spills or splashes of Viebeam CO must be rinsed away with water immediately. Empty containers should be rinsed with water immediately after use. The primary field of application for Viebeam CO is pickle bleaching of heavily pigmented hides and skins. The product is added to the salt bath and run for 15 – 30 mins before addition of acids. Pickling is carried out in the usual way but care must be taken not to open the drum during the process. At the end of pickle bleaching, any excess chlorine dioxide remaining must be neutralised with a reducing agent such as sodium thiosulphate or sodium bisulphite. Potassium iodide-starch paper is used to test for complete removal of the excess oxidising agent. Reptile skins can also be bleached with Viebeam CO . Unlike permanganate bleaching, Viebeam CO bleaching does not impair tensile strength. Viebeam CO can be used to lighten or completely bleach faulty dyeings. In this case, the degree of bleaching will depend on the structure of the dyes to be bleached.

Sample applications:

• Pickle bleaching of hides: up to 1 %, based on pelt weight

• Pickle bleaching of lizard and reptile skins: up to 10 %, based on pelt weight

• Bleaching of vegetable tanned reptile skins: up to 150 %, based on dry weight of skins

• Bleaching of faulty dyeings: up to 20 %, based on the crust weight

Viebeam RS – Liming auxiliary for zero or low sulphide systems

APPLICATION:

Viebeam RS is a synergistic blend of Mercaptans and Amines. Yield is dramatically increased and wrinkles are reduced and also fats are broken down. Increase of yield of 3 – 5% has been experienced. The Amines smooth out wrinkles and reduce unwanted Beamhouse smells, the Mercaptans break the Keratin bond allowing hairs to fall out

VIEBEAM RS Application:

Viebeam RS can be diluted with cold water and added to the vessel in the normal way. Suitable for use on all hide or skin types. The reduced swelling effect helps to give a smooth, fine grain on the leathers. The product does possess an unhairing effect, the reduction in swelling also enhances the effect of sulphides if they are used, giving a more effective removal of hair root / scud from the grain. The advantage of their use is that they considerably reduce the amount of sulphide consumed and discharged with the wastewater. On the other hand, these chemicals are much more expensive than sulphides. Owing to their high price, these products are mostly used in instances where effects other than environmental improvement are sought . For example, liming with these compounds yields a lower degree of swelling than using lime and sulphide only. This may be expected to have a positive effect on the area yield and the smoothness of the grain.
