Abstract
Способ изготовления древесностружечных плит предусматривает смешивание древесной стружки с фенолформальдегидным вяжущим и карбамидом, формирования ковра, прессовку. В качестве фенолформальдегидного вяжущегое используют пульвербакелит и жидкостный олигомер форконденсат фенола и формальдегида, вводят оксид магния. При этом карбамид предварительно вносят и растворяют в форконденсате фенола и формальдегида и смешивают с древесной стружкой, после чего прибавляют пульвербакелит и оксид магния.
