摘要:
A description is given of additives for the extrusion of construction material systems, characterized in that the additives comprise irreversibly crosslinked cellulose ethers having gel-like rheological properties, and the use of irreversibly crosslinked cellulose derivatives as additives for the extrusion of construction material systems and also of an extrusion process for construction material systems.
摘要:
The present invention relates to a process for preparing cellulose ether products which is characterized in that superabsorbent polymers (SAPs) are dried and milled, or mill-dried, conjointly with moist cellulose ether and also to the cellulose ether products resulting from this process.
摘要:
The present invention relates to water-soluble, particularly ternary, preferably ionic, cellulose mixed ethers, more particularly to anionic water-soluble cellulose mixed ethers, as additives for drilling fluid applications.
