Pembuatan Destro.Fosfat Dari Pati Sagu Sebagai Ekstender Perekat Kayu
Abstract: Materials making of
Destro Phosphate are from Sago Extract. Sago extract is materials which
containing many carbohydrate is kind of macromolecules which consist of amylase
and amilopektin which have a lot hydroxyls. This hydroxyl bunch eams
subsititution with phosphate so that its use to be mounts. This bunch hydroxyl
substitution can be conducted with HCL for the hydrolysis and OH substitution
with Natrium Hydro – Phospate. Singeing conducted at temperature 80° - 130 °C during 15 - 30 minute. Continued
with addition hidrogen natrium of phosphate and dried. Then reacted to heat at
temperature 12O° - 170 °C during 2 hour. Characteristic of sarnple cover
physical test, chemical test and morphology test with SEM. From analysis result
obtained that Destro phosphate can be made isn't it sago extract with hydrogen
natrium of phosphate. With draracteristic as follows: pH = 6,2 ; viscosities =
3, 68 cp and densities = 1,0004 gr/cc.
