Production of particle Boards Using Adhesives and Cellulosic

Abstract

The aim if this study is the Production of new types of cellulosic adhesives used in partition, office furniture and household utensils. The research employs the cellulose from cellulosic plant and use unemployed plants like mesquite. The binding for cellulose materials investigated comprised, Gum Arabic, Guar, Nocrine and other polymer formulations. The research used ordinary glassware, balance and iron and wood moulds to give the desired shapes. The products were tested using hardness tester for the adhesion strength and moisture absorption for the efficiency, The Result obtained were as follows: Mesquite + gum Arabic =54.9 N, (N for Newton) Mesquite + Guar =43.2 N Mesquite +Musk wood by Gum Arabic = 43.00 N Okra + Gum Arabic =44.6 N Mesquite +Okra by Gum Arabic = 42.2 N

For humidity and moisture contents the following result were obtained: Okra +Gum Arabic: Okra by Gum Arabic the original weight was (8g) , after one hour gave (9.7g), and after two hours (12.9g) then after 3 hours (12.1g) the sample was swelling by water. Mesquite +Gum Arabic: Mesquite by Gum Arabic the original weight was (17.4g), after an hour gave (29.2g), after 2 hours (30.4g) then after 3 hours the increased of water content great (30.9g) which indicate the capacity of water regain. Mesquite +Musk wood and Gum Arabic: (4.9g) of Gum Arabic by mesquite and musk wood was weight, after hour gave (4.9g), after 2 hours gave (5g) then after 3 hours gave (4.2g) Mesquite +Okra and Gum Arabic: Okra and mesquite by Gum Arabic the original weight was (5.2g), then after an hour gave (5.3g), after 2 hours (8.7g) then after 3 hours (6.9g) as increased by water absorption. Mesquite + Guar: Weight was (11.3g), and then after one hour gave (19.2g), after 2 hours (16.6g) then after 3 hours (9.6g) the increased of water contain followed decrease of water contain indicate the disintegrated of the sample by water
