Pengaruh Kekentalan (Viskositas) Lateks terhadap Konsenttrasi Asam Asetat pada Benang Karet

Abstract

Latekx is a milky colloidal liquid from tree of rubber(Hevea Brasiliensis) with the rubber particle disperted water.Latex contain protein(while of egg) which capable to pieces by bactery activity.Viscocity of extrusion process has 75-160cps standard at temperature 17C.If viscocity did not reach 75cps hence a result rubber threadwill be easy to be moulder and easy to break an if is viscocity is bigger than 160cps hence the filament wide of rubber thread too big extrusion process will be difficult because will gag at capillary pipe if the rubber ythread forming.Viscocity was checked in the same time in chemistry laboratory,than it was processed,at last all the process would product rubber articles.The measuring of viscocity was done once in six hours in chemistry laboratory and so like to determined th
