Abstract:
Bei einer Vorrichtung zum Übertragen eines Drehmoments auf einen Drehrohrofen (13) mit einer von einem Motor (1) angetriebenen Antriebswelle (4) mit einem Antriebsritzel (5), das einen mit dem Drehrohrofen (13) verbundenen Zahnkranz (12) antreibt, treibt das Antriebsritzel (5) den Zahnkranz (12) unter Zwischenschaltung eines Getriebes (6) an, wobei ein Zahnrad (7) des Getriebes (6) in axialer Richtung verschieblich mit dem Antriebsritzel (5) in Eingriff steht.
Abstract:
The present invention relates to the technical field of treated mineral filler products. The invention further relates to a process for preparing such treated mineral filler products, and to its preferred use in the field of plastic applications, and in particular polypropylene (PP)-or polyethylene (PE)-based breathable or extrusion coating film applications.
Abstract:
The present invention relates to the domain of mineral filler treatment processes. The process for the preparation of a treated mineral filler product comprises the following steps: (a) treating at least one dry mineral filler with at least one Group II or Group III salt of a C8 to C24 aliphatic monocarboxylic acid to produce an intermediate mineral filler product; followed by (b) treating the intermediate mineral filler product of step (a) with at least one C8 to C24 aliphatic monocarboxylic acid to produce a treated mineral filler product. Applications in particular to prepare treated mineral filler products (such as Ca carbonate) to be used in plastic applications such as in polypropylene (PP) - or polyethylene (PE) - based breathable or extrusion coating film applications.
Abstract:
The present invention relates to a process for preparing a surface treated mineral filler product, and to its preferred use in the field of plastic applications, and in particular polypropylene (PP)-or polyethylene (PE)-based breathable or extrusion coating film applications.
Abstract:
The present invention relates to treated mineral filler products comprising a) at least one mineral filler, b) a treatment layer located on the surface of said mineral filler(s), said treatment layer comprising at least one saturated C 8 to C 24 aliphatic carboxylic acid; and at least one di and/or trivalent cation salt of one or more saturated C 8 to C 24 aliphatic carboxylic acid, wherein the weight ratio of all of said aliphatic carboxylic acid salt(s) : all of said aliphatic carboxylic acid(s) is from 51 :49 to 75:25; and said treatment layer is present in an amount of at least 2.5 mg/m 2 of said mineral filler. Furthermore the present invention relates to processes to prepare such treated mineral filler products, and to their uses, notably in plastic applications, and especially in polypropylene (PP)- or polyethylene (PE)-based breathable or extrusion coating film applications.
