Sols et Paysages

Très bel ouvrage, écrit par deux passionnés, détaillant les relations entre paysages et types de sols sur une douzaine d’exemples différents.

Ce livre écrit par deux universitaires est très agréable à lire et explique en détails les principaux types de sols que l’on trouve en Europe et leur incidence sur la végétation et l’utilisation des terrains correspondants.

Cet ouvrage décrit de façon détaillée un grand nombre de sols en croisant les observations sur le terrain, les analyses en laboratoire et en s’appuyant sur la bibliographie et l’expérience des deux auteurs. A partie de ces données sont expliquées la formation du sol et ses incidences sur la végétation et l’exploitation des terrains correspondants.

L’incidence de l’habitat, de l’agriculture, de l’exploitation du sous-sol sont prises en compte ainsi que leurs incidences sur le sol.

Une autre partie traite plus en profondeur les usages du sol qu’ils soient urbains, forestiers, agricoles, viticoles ou autres.

Ce livre est abondamment illustré de photos et croquis.

Il s’adresse à tout professionnel ou futur professionnel dans ce domaine ou dans des domaines proches (agriculture, exploitations forestières ou minières…) mais aussi à toute personne convaincue de l’importance du sol et de l’impératif de le protéger.

Very strong growth in Internet sales of wheels for mirrors machines.

Vedip, the first European web site (French origin) Internet sales of Italian wheels for mirrors machines saw its revenues for the second 2019 quarter  increased by more than 67 %.

The strategy developed by Vedip to propose, in partnership with a leading Italian manufacturers of wheels and diamond core drills for glass, very competitive prices  for working only on the Internet, detailed fact sheets with photos, standard wheels made by manufacturers / Machines / Positions, alternative wheels and a telephone support seems to meet the needs of the market in Europe mirrors.

The site already has 1741 tools now online  continues  to improve the technical data of the tools and the number of referenced machinery (over a hundred).

On Vedip you can view the data sheets (with photos and price) of the wheels for the main flat glass processing machines of the market (straight line edging machines, CNC, drills, double edger, chamfering ...) and the most important suppliers (Intermac, Bovone, Glaston, Bavelloni, Lattuada, Schiatti, JANBAC Baudin, Battelino, Denver, Bimatech, Ada, Besana, Bottero ....).

Water treatment installations

 

The main reason for water treatment during glass and stone processing are:

 

The anti-pollution rules in the area where the workshop is located

Environmental deference

Cost reduction by an important decreasing in used water quantity and in tools (wheels).

Profit for the machines cleaning time and maintenance cost decreasing.

Improving for glass processing quality.

The water is mainly used to cool the tools (wheels) and the glass. When the silica is not removed from the water the cooling property decrease and the processing temperature is not the right one to have a good processing quality and to have a good duration for the wheels.

On the market exist 3 main technologies

Centrifugation:
benefits:

no chemical products

disadvantages:

does’nt remove the very small glass particles

Purchase cost

Maintenance cost

electrical consumption

Noise


Centrifuges with wheels exist on the market. This way you can move the centrifuge from one machine to another one when you have only 2 or 3 machines in your workshop. In case you have more machines you have to install a fix centrifuge and to connect it with your water treatment network.

Some suppliers propose to add to the centrifuge a flocculation installation to remove the smaller glass particles.

Flocculation:
Good results if the supplier has a good experience and if the machine is properly designed. You have also to find out the best flocculant for your activity (glass or stone or both materials).


Filtering:
Here no miracle. There are also on the market systems associating flocculation and filtering.

 

 

Before to take a decision you have to check if the water quality after treatment allow you to use this water to cool the spindle for a CNC machine (internal cooling).

 

In case of important temperature the water treatment installation can produce some smell. It is better to have the main part of the installation outside the working area.
