Because MDI adhesive does not contain formaldehyde, and extremely volatile low, because this is in manufacturing process can huge avoids the chemical material harm to human body.water-resistant balcony decking Russia And the chemical material that the board that MDI adhesive produces passes high temperature solidify to form stability, won't release material of formaldehyde etc organic chemistry, the to the environment pollution in putting an end to a product to use.
Of MDI adhesive stick receive a principle to be different from a tradition 3 aldehyde glue. 3 aldehyde adhesive is the tradition physics is stuck receive, and MDI is stuck for steel wood composite beam fasteners analysis chemistry receive. In MDI - NCO radical group can be divided with the water in lumber and in cellulose - OH happening chemistry reacts, form stable chemical material.
From microcosmic on look, can make material forms the cross-linking between the element, make thereby traditional " the face is stuck receive " reduce for " how to laminate angle stair the dot is stuck receive " , huge reduced adhesive to use an amount. Generally speaking, differentiate according to different OSB grade, the use quantity of MDI is in 9-24kg/m3 , be equivalent to a tradition only the 1/4 of 3 aldehyde glue, 1/5.
