摘要

Today,because the existing forests are gradu-ally decreasing,there are various obstacles in pro-ducing industrial wood products.Particularly re-garding this subject,alternative and environmental methods are sought,as in all hielasohiqh sarYse a fterregard,studies about particleboard,which arose after agricultural production,have great imporarnmstalkuse of stalk with particleboard production from stalk will provide economic profit,a new employmentarea and ecological production.In our study,we pro-duced particleboards by mixing cotton stalk and com stalk with urea-fomaldehyde in certain proportions.After that,particleboards are compared in terms of physical and mechanical properties.Particleboardsare produced by using 12% urea-formaldehyde gluein 10 minutes press and at 175C press temperature.As a result,the particleboard D.twhhn tho biohestwith (75% Com,25% Cotton) stalk has the highest bending strength with 7.839r N the obtained par-surface deflagration temperature in the obtained par- ticleboards is seen in sample E (100%Corn) with156 C value.The lowest value in water retentionrate is seen in sample E (100% Corn) with 17%.Thelowest value in the coefficient of heat transmissionwas found in sample B (75% Cotton,25% Corn) as0.1458 W/mK.
