Abstract
ผลิตภัณฑ์ปฏิกิริยาในน้ำของสารผสมที่อาจประกอบเป็นสำคัญด้วยแหล่งของกรดที่มี pKa ในน้ำประมาณ 2 ถึงประมาณ 8 แหล่งของเบสที่มี pKb ในน้ำประมาณ 2 ถึงประมาณ 6 และยูเรีย สารผสมยูเรีย/ฟอร์มัลดีไฮด์เรซินที่สามารถบ่มอาจมียูเรีย/ฟอร์มัลดีไฮด์เรซินที่สามารถบ่ม และ สารผสมก่อหน้า และอาจถูกผลิตโดยการรวมเรซินกับสารผสม ผลิตภัณฑ์ไม่ที่ถูกประกอบใหม่ อาจถูกผลิตโดยการรวมวัสดุลิกโนเซลลูโลสิกอนุภาคกับเรซินที่สามารถบ่มก่อนหน้า และการบ่มเร ซิน อาจเลือก แผงไม้ที่ถูกประกอบใหม่อาจมีวัสดุลิกโนเซลลูโลสิกอนุภาคและสารผสมสารประสาน ซึ่งประกอบด้วยผลิตภัณฑ์ที่ถูกบ่มของเรซินที่สามารถบ่มและผลิตภัณฑ์ปฏิกิริยาในน้ำที่กล่าวถึง ก่อนหน้า สารเข้มข้นสำหรับการก่อรูปสารผสมที่เพิ่มการโพลีเมอไรเซชั่นอาจประกอบเป็นสำคัญ ด้วยแหล่งของกรดที่กล่าวถึงก่อนหน้า แหล่งของเบสที่กล่าวถึงก่อนหน้า และยูเรีย Aqueous reaction products of potentially viable mixtures with 2 to 8 pKa aqueous acid sources, bases with 2 to approx.6 pKb in water, and urea / urea mixtures. Curing formaldehyde resins may contain urea / formaldehyde resins and curing agents. And may be produced by combining resins with mixtures. The product has not been reassembled. May be produced by combining particle lignocellulosic material with previously cured resins and resin curing. Reconstituted wood panels may be selected with lignocellulous material, particles and Binder mixture This consists of cured products of the curing resins and the aqueous reaction products mentioned earlier, formation concentrates, additives that increase polymerization may be essential. With the sources of acids mentioned earlier The previously mentioned base sources and urea.
