Biodegradable hydraulic fluid base oiri yeHFD-U system
Hydraulic fluid base oiri yeHFD-U system
Inoshandiswa muHFD-U system.Kuenzaniswa nezvigadzirwa zvakafanana, vane zvinotevera maitiro:
Yakanyanya kuchena mhando inopa yakanakisa kuburitswa kwemhepo uye anti-foam chivakwa.
Good demulsibility inosangana nezvinodiwa nehutsanana.
Zvigadzirwa zvakasarudzwa zvinopa yakanaka anti-oxidant uye hupenyu hurefu pfuma.
Inoshamisa lubricity inosangana nezvinodiwa zvepakati-yepamusoro pressure system.
High flash point uye fire point inopa kuita kwakanaka kwekudzivirira moto.
Hydrolysis kuramba haisi nyore kukanganisa kuchengetedza lubricity.
Lower kudurura poindi yakakodzera yakaderera tembiricha kushanda.

Yakazara Synthetic hydraulic fluid base mafuta
Yakasarudzwa chimiro chemvura insoluble polyether.
Inokodzera mamiriro akaoma epamusoro uye kupisa kwepamusoro.
Chekupedzisira chigadzirwa chakawanikwa FM Giredhi II.
