Özet:

 In this study, the surface changes glossiness, whiteness index WI, and color and shore D hardness value after the application of different wood bleaching agents single-and two-component on bulletwood Manilkara bidentata A.DC. A. Chev. wood were investigated. According to the obtained results, in the variance analysis tests, the glossiness values at  and 20o were determined as insignificant for the type of bleaching chemical, while all other tests were found to be significant. The Shore D hardness value was determined as 70.30 HD. E values were determined as 4.56 for the single-component and 7.21 for the two-component bleaching agents. The brightness values in both applications at 60o and 85o, both parallel and perpendicular to the fibers, decreased, while L, b, and C values increased.

 Bu çalışmada, farklı ahşap ağartıcı tek ve çift komponentli kimyasallarının bulletwood Manilkara bidentata A.DC. A. Chev. ahşabında uygulanması sonrasında meydana gelen yüzey değişimleri parlaklık, beyazlık indeksi WI ve renk ve shore D sertlik değeri araştırılmıştır. Elde edilen sonuçlara göre, varyans analizi testlerinde ağartma kimyasalı türü için ve 20ode parlaklık değerlerinin anlamsız olarak belirlenirken, diğer bütün testler anlamlı olarak bulunmuştur. Shore D sertlik değeri 70.30 HD olarak elde edilmiştir. E değerleri tek komponentlide 4.56 ve çift komponentlide 7.21 olarak tespit edilmiştir. Her iki kimyasallara ait uygulamalar ile 60o ve 85olerde liflere paralel ve dik yöndeki parlaklık değerleri azalmış, L, b ve C değerleri ise artmıştır.
