摘要:
The present invention relates to a method for providing at least one concentrate of at least one solute for the production of at least one dialysis solution, the method comprising the following steps: providing at least one container which contains at least one solid to be dissolved; supplying water to the container to dissolve the solid; removing the concentrate of the solute from the container and replenishing with water; measuring the concentration of the solute or of a parameter correlated with the concentration; and temporarily or permanently stopping replenishment with water if the measured concentration value of the solute falls below a first threshold value or the value of the parameter falls below or exceeds a first threshold value or if a change in the concentration value of the solute or in the value of the parameter exceeds a first threshold value.
摘要:
La présente invention concerne un procédé de dissolution contrôlée d'un matériau cristallin formé de plusieurs sortes d'ions, dans une solution contenant un solvant du matériau cristallin. La solution contient, avant dissolution, au moins deux sortes d'ions du matériau cristallin. La concentration molaire en ion de chaque sorte est supérieure à zéro et inférieure à la concentration molaire en ion de chaque sorte qu'aurait la solution à saturation, si elle contenait l'ensemble de ions constitutifs du matériau cristallin, dans les conditions de température et de pression de la dissolution. Application: usinage chimique de matériaux piézoélectriques notamment de berlinite.
摘要:
Verfahren zum Lösen von Kautschuk, Kunststoffen und ähnlichen Elastomeren, in einem organischen Lösemittel. Das zu lösende Elastomer und das Lösemittel werden in einem vorbestimmbaren Verhältnis in einen verschließbaren Mischebehälter gegeben. Der Mischbehälter wird nach dem Verschließen in Mischbewegungen versetzt, bis eine Lösung gleichmäßiger Konsistenz erreicht ist.

Die Erfindung betrifft ein Verfahren zum raschen Auflösen von wasserlöslichen Polymeren in Wasser, indem man in das vorgelegte fein verteilte Polymere unter Druck Wasser in fein verteiltem Zustand einbringt. Das wasserlösliche Polymere kann in Form einer W/O Emulsion oder in Form einer Pulver-in-ÖI-Suspension vorliegen; das Wasser wird bevorzugt unter Druck tangential zur Overfläche des vorgelegten Polymeren eingedüst.

Apparatus for contacting solid particles with a liquid in a vessel having an agitator within a vertical draft tube, for instance for dissolving phosphate rock particles in acid, is characterised by means for supplying fluid under pressure to a bottom portion of the vessel to prevent solids settling and to resuspend solids that have settled, e.g. after shutdown. Apparatus for similar purposes is disclosed having a vent for minimising foaming. Also disclosed is a method of start up a continuous phorphoric acid production process in a multi-vessel system comprising four vessels (2), (16), (28) and (48).

A solid product dispenser can be used to form a dilute liquid solution from a block of solid concentrate. In cases where only a small amount of liquid solution is needed, the solid product dispenser may dissolve the block of solid concentrate quickly and substantially uniformly to provide a solution of controlled concentration. This can be contrast with larger dispensing applications where a dispenser may dissolve a block of concentrate slowly at the start and more rapidly as the dispensing progresses, producing a solution with an average concentration higher than if only a small amount of solution were produced using the dispenser. In one example, the solid product dispenser includes a fluid distribution reservoir and a solid product reservoir positioned inside of the fluid distribution reservoir and over a platform on which the solid product sits. High pressure fluid flows between the two reservoirs, turbulently contacting the solid product.
摘要:
An object of the present invention is to provide a water containing permanganate ions that exist stably over a long period of time and a method for producing the water. A water containing permanganate ions of the present invention as a means for resolution is produced by dissolving 0.1 µM to 1 mM of a divalent manganese compound, 0.1 µM to 1 mM of an organic iron compound, and 1 to 300 mM of an inorganic salt in a water with ozone-microbubbles generated using an ozone gas at a concentration of 1 to 300 g/Nm 3 . The half-life of permanganate ions of the water containing permanganate ions of the present invention is 3 months or longer, for example, when the water filled in an airtight container under atmospheric pressure is stored under a temperature condition of 40°C, and has significantly different properties from a water containing permanganate ions that is produced by dissolving a permanganate compound in water, although the two waters share a common point of containing permanganate ions.
