Abstract
Способ изготовления малотоксичной волокнистой плиты включает смешивание растительного волокна с карбамидоформальдегидным вяжущим, высушивание, формовку ковра и прессовку. В карбамидоформальдегидную смолу в процессе приготовления вяжущего вводят водный раствор карбамида, жидкого стекла и казеинового клея в количестве от 0,5 до 5,0 % от сухого остатка смолы, а волокно перед проклейкой вяжущим обрабатывают тем же водным раствором в количестве от 1,0 до 10,0 % по сухой массе от абсолютно сухого волокна.
