USE OF CELLULOSE ETHER COMPOUNDS FOR INCREASING THE OPEN TIME AND IMPROVING THE WETTABILITY OF CEMENT-BASED MORTARS

The present invention relates to cellulose ether compounds for increasing the open time and improving the wettability of cement-based mortars. The inventive cellulose ether compounds are formed from cellulose ether with one or more liquid antifoams incorporated therein. The inventive cellulose ether compounds are preferably used as modified cellulose ether in dry mortars for increasing the open time. 本申请涉及纤维素醚化合物用于增加水泥基砂浆的开放时间和改善水泥基砂浆的湿润性的用途。描述了由纤维素醚和一种或多种液体消泡剂组成的配混料的用途。其优选用作干砂浆中的改性纤维素醚以增加开放时间。
