Description
Изобретение относитс к деревообрабатывающей прокиишенности, в частности к способам изготовлени древесностружечных плит.This invention relates to a woodworking industry, in particular to methods for producing particle boards.
Известен способ производства стружечных плит, состо щий из нанесени на плиты влагозащитного покры ти и отверждени его Г13A known method for the production of particle boards, consisting of applying a moisture-proof coating to the plates and curing it with G13.
Известен также способ производства древесностружечных плит с влагоза цитным покрытием, включающий формирование ковра, прессование, охлаждение плит, нанесение на них влагозащитного покрыти на основе дисперсии каучука с добавлением красител t2.There is also known a method of producing particleboard with moisture by a citric coating, which includes forming a carpet, pressing, cooling the plates, applying a moisture protective coating on them based on rubber dispersion with the addition of dye t2.
Недостатками известных способов &л ютс низка 1 адгези покрыти к плитам и высокое врем подсушки. The disadvantages of the known methods & low 1 adhesion of the coating to the plates and high drying time.
Цель изобретени - повьшение адгезии к плитам и снижение времени ПОД1СУШКИ. покрыти .The purpose of the invention is to increase the adhesion to the plates and reduce the time of the first dry. cover
Эта цель достигаетс тем, что . охлаждение плит осуществл ют до 40-50 С.This goal is achieved by the fact that. cooling of the plates is carried out to 40-50 C.
Предлагаемый способ .осуществл ют следующим образом.The proposed method is carried out as follows.
На древесностружечные плиты, вышедшие из пресса и охлажденные до 40 50с, методом окунани или распы лени нанос т смесь водной дисперси каучука с красителем. После нанесени покры ти плиты подсушивают в сушильных камерах при в течение 15-20 мин. A mixture of water dispersion of rubber with a dye is applied by dipping or spraying onto the chipboard plates that came out of the press and cooled to 40–50 s. After coating, the plates are dried in drying chambers for 15-20 minutes.
Сравнительные данные известного и предложенного способов приведены ( таблице.Comparative data of the known and proposed methods are given (table.
Предлагаекый способ позвол ет сократить врем на получение влаго защитного покрыти в 3 раза, так как не приходитс ждать охлаждени плиты до нормальной температуры.The proposed method makes it possible to reduce the time required to obtain a moisture protective coating by 3 times, since one does not have to wait for the plate to cool to normal temperature.
За счет использовани плит с температурой 40-50 С сокрсццаетс врем подсушки покрыти , после его нанесени Due to the use of plates with a temperature of 40-50 ° C, the drying time of the coating after its application is shortened
в 2 раза, т. е. до 20 мин, в то зрем , как по известному способу оно составл ет 40-50 мин.2 times, i.e., up to 20 minutes, while we sleep, as in a known way, it is 40-50 minutes.
Определение адгезии вЛагоз;ащитнОго покрыти методом решётчатого надреза показало, что адгези по предлагаемому способу составл ет 80%, а по известному - 50%.Determination of adhesion in Lagoz; protective coating by the method of lattice cut showed that adhesion by the proposed method is 80%, and by the known - 50%.
