Son yıllarda orman ürünleri sanayisinde
önemli bir yer işgal eden ahşap malzemelerin korunmasında kullanılan kimyasal
emprenye maddelerinin yerine alternatif doğal emprenye maddeleri aranmaktadır.
Bu çalışmada, Ülkemizde hammadde olarak bol bulunan borlu bileşikler (boraks ve
borik asit) ile doğal emprenye maddelerinden olan kebrako kullanılmıştır.
Emprenye işleminde borlu bileşiklerin %1, 3 ve 5’lik sulu çözeltileri
kullanılmıştır. Deney örneklerinin emprenyesi ASTM D 1413-76 esaslarına göre
yapılmıştır. Emprenyeli örneklerin tam kuru yoğunluk, retensiyon miktarı,  eğilme direnci, elastikiyet modülü, liflere
paralel basınç direnci, liflere paralel yapışma direnci ve vida tutma direnci
testleri yapılarak kontrol örnekleri ile kıyaslanmıştır. Sonuç olarak, yapılan
testler sonucunda retensiyon, tam kuru yoğunluk, liflere paralel basınç ve vida
tutma dirençleri kontrol örneklerinden daha yüksek çıkmıştır. Eğilme direnci,
elastikiyet modülü ve liflere paralel yapışma dirençleri ise kontrol
örneklerinden daha düşük çıktığı tespit edilmiştir. Emprenye sonrası deney
örneklerinde borlu bileşiklerin konsantrasyonları arttıkça direnç değerlerinde
düşüş, tam kuru yoğunluk ve retensiyon miktarlarında ise artış görülmektedir.
Borlu bileşiklerden boraks ile emprenye edilen örneklerde değerler borik asit
ile emprenye edilenlerden daha yüksek çıkmıştır.

In recent years, alternative natural
impregnation materials are being sought as substitutes for chemical
impregnation materials used for conserving wooden materials; therefore, such
natural materials have acquired significance in the forest products industry.
In this study, the boron compounds borax and boric acid, which are abundant raw
materials in Turkey, and quebracho, a natural impregnation material, were used.
For the impregnation process, aqueous solutions of 1%, 3%, and 5% boron
compounds were utilized. The test samples were impregnated according to ASTM D
1413-76 principles. Oven-dry density, retention rate, bending strength, elastic
modulus, compression strength parallel to fibers, bonding strength parallel to
fibers, and screw holding strength tests of the impregnated samples were
measured, and the results were compared with those of control samples. The
retention, oven-dry density, comprehension parallel to fibers, and screw
holding strength of the samples were found to be higher than those of the
control samples, whereas bending strength, elastic modulus, and bonding
strength parallel to fibers were lower. After impregnation, it was observed
that there was a decline in strength values and a rise in retention rates with
the increase in the concentrations of boron compounds. The values for samples
impregnated with borax were higher than those for the samples impregnated with
boric acid.
