Biodegradable hydraulic fluid base base bakeng sa sistimi ea HFD-U
Oli ea motheo ea mokelikeli oa Hydraulic bakeng sa sistimi ea HFD-U
E sebelisoa ho sistimi ea HFD-U.Ha li bapisoa le lihlahisoa tse tšoanang, li na le litšobotsi tse latelang:
Boleng bo phahameng ba bohloeki bo fana ka tokollo e ntle ea moea le thepa ea anti-foam.
Demulsibility e ntle e kopana le litlhoko tsa bohloeki.
Lisebelisoa tse tala tse khethiloeng li fana ka thepa e ntle ea anti-oxidant le bophelo bo bolelele.
Lubricity e tsotehang e kopana le litlhoko tse akaretsang tsa tsamaiso ea khatello e phahameng ea bohareng.
Sebaka se phahameng sa flash le sebaka sa mollo se fana ka ts'ebetso e ntle ea thibelo ea mollo.
Ho hanyetsa ha hydrolysis ha ho bonolo ho senyeha ho boloka mafura.
Sebaka se tlase sa ho tšela se loketseng ts'ebetso ea mocheso o tlase.
