Abstract
มวลรวมซึ่งประกอบด้วยเส้นใยเซลลูโลสซึ่งทำขึ้นจากชิ้นส่วนวัสดุซึ่งประกอบด้วยเส้นใยเซลลูโลสโดยกรรมวิธีซึ่งประกอบด้วย ระยะทำให้อ่อนตัวซึ่งประกอบด้วยการทำให้ชิ้นส่วนของวัสดุซึ่งประกอบด้วยชิ้นส่วนของเส้นใยเซลลูโลสจำนวนมากอ่อนตัวโดยการกระทำของสารทำให้อ่อนตัวในน้ำที่อุณหภูมิสูง ซึ่งจะทำให้การเชื่อมขวางของเซลลูโลสในวัสดุซึ่งประกอบด้วยเส้นใยเซลลูโลสนั้นแตกออกอย่างน้อยบางส่วน ระยะอัดซึ่งประกอบด้วยการอัดชิ้นส่วนที่อ่อนตัวของวัสดุซึ่งประกอบด้วยเส้นใยเซลลูโลสเข้าด้วยกันเพื่อให้เกิดเมทริกซ์อัด และ ระยะรวมเข้าด้วยกันซึ่งประกอบด้วยการขจัดน้ำและทำให้เมทริกซ์อัดแล้วนั้นรวมกันเพื่อให้เกิดเมทริกซ์ซึ่งรวมเข้าด้วยกันและกรรมวิธีสำหรับเตรียมซึ่งประกอบด้วยระยะทำให้ อ่อนตัว ระยะอัดและระยะรวมเข้าด้วยกันดังที่กล่าวมาก่อนแล้ว Cellulose fiber aggregates, which are made from a material fragment composed of cellulose fibers by a process consisting of Softening phase, which consists in softening parts of a material consisting of fragments of cellulose fibers by the action of a softener in water at high temperatures. This causes the cellulose crosslinking in the material to be comprising at least partially fragmented cellulose fibers. The compression phase consists of compressing the soft parts of the material consisting of cellulose fibers together to form an extruded matrix and the joining phase consisting of dehydrating and making the extruded matrix combine to provide An aggregation matrix is formed and a preparatory process comprising the softening stage, the compression stage and the aggregation stage as mentioned above.
