Abstract

PROCEDE DE PREPARATION D'UN SUBSTRAT GRANULEUX CONVENANT EN PARTICULIER POUR LES HYDROCULTURES, PAR CALCINATION DE GRAINS OU GRANULES CONTENANT DE L'ARGILE. ON UTILISE D'ABORD, POUR LA PREPARATION DES GRAINS OU GRANULES, UN MELANGE D'UNE ARGILE QUELCONQUE ET DE KIESELGUHR DANS DES PROPORTIONS RELATIVES DE 70 A 50 PARTIES EN POIDS D'ARGILE ET 30 A 50 PARTIES EN POIDS DE KIESELGUHR, EQUILIBRE SELON LA TENEUR EN SELS DU KIESELGUHR, ET ADDITIONNE DE 50 PARTIES EN POIDS D'EAU, PAR RAPPORT AU MELANGE ET, APRES SECHAGE DES GRAINS OU GRANULES, ON LES CALCINE A DES TEMPERATURES SUPERIEURES A ENVIRON 750C OU PLUS PENDANT 0,3 A 2HEURES.PROCESS FOR PREPARING A GRANULAR SUBSTRATE SUITABLE IN PARTICULAR FOR HYDROCULTURES, BY CALCINATION OF GRAINS OR GRANULES CONTAINING CLAY. FOR THE PREPARATION OF THE GRAINS OR PELLETS, A MIXTURE OF ANY CLAY AND KIESELGUHR IS FIRST USED IN RELATED PROPORTIONS OF 70 TO 50 PARTS BY WEIGHT OF CLAY AND 30 TO 50 PARTS BY WEIGHT OF KIESELGUHR, BALANCED ACCORDING TO THE SALT CONTENT OF KIESELGUHR IS 50 PARTS OF WATER WEIGHT, RELATED TO THE MIXTURE AND, AFTER THE GRAINS OR PELLETS, ARE CALCINATED AT TEMPERATURES GREATER THAN ABOUT 750C OR MORE FOR 0.3 TO 2 HOURS.
