| Résumé : |
Silicon and oxygen are the most abundant elements on earth. When chemically combined they form naturally occuring silicon dioxyde and silicates with widely differing structures. Minerals found in nature and based on these elements are numerous.
Silicates have been widely used in technical applications for a long time. Pure silicon as a material for electronic components laid the foundations of the computer age has had a crucial influence on our era.
In leather manufacture, by contrast, the silicon compounds have so far been of only minor importance. With the development of a specific colloidal aqueous suspension of silicon dioxyde gel, a major step has been taken toward making this class of substances accessible to and usable in leather manufacture.
This compound enables pelts to be processed into wet white, a stabilized hide material that can be subjected to mechanical operations and then can be subjected to mechanical operations and then to any kind of tanning. the hide waste producted in splitting, shaving, and trimming is free from environmentally polluting chemicals and presents no problems in disposal or recycling. Since the collagen is hardly altered by silica (unlike wet white processed with tanning agents that affect the collage fibre structure), subsequently tanned hides retain their charactéristic properties and undergo no adverse changes. This also means no restrictions need be placed on the collagen offal of trimming and shaving, which expands the array of their possible uses and value in the market. |
