Nigrol a i ʻole tad 17. ʻO wai ka maikaʻi?
Nā mea
Hoʻopuehu ma nā huaʻōlelo
Pono e hoʻomaka me ka ʻoiaʻiʻo i ko mākou manawa ʻelua mau manaʻo e noho pū ana: "Nigrol" a me nigrol. Pono nā ʻōlelo. I ka hihia mua, ke kamaʻilio nei mākou e pili ana i ka hōʻailona o ka ʻaila gear, i hana ʻia e kekahi mau hui (ma Rusia, no ka laʻana, ʻo FOXY, Lukoil a me kekahi mau mea ʻē aʻe). Ma ka lua - e pili ana i ka inoa nui o nā lubricants i loaʻa mai kekahi mau ʻano o ka aila, a me ka loaʻa ʻole o kahi pākēneka o nā mea resinous, ʻo ia ke kumu i loaʻa ai ko lākou inoa (mai ka huaʻōlelo Latin "niger").
No ka nigrol maʻamau, ʻo ka aila mai nā māla Baku ka mea mua, ʻoiai no ka hana ʻana i nā lubricants hou o kēia brand, ʻaʻohe kumu koʻikoʻi ke kumu kumu. No laila, ʻokoʻa nā manaʻo o ka hōʻailona a me ka hoʻohui ʻana o kekahi mea, no laila ua like ʻo Nigrol a me Nigrol i ka wahi o ka hoʻohana pono ʻana (ʻaila gear) a me ke kumu kemika - nā aila naphthenic - kahi i hana ʻia ai ka huahana. A ʻo ia nō!
Hoʻohālikelike i nā kikoʻī
No ka mea ʻaʻole hoʻohana ʻia ka nigrol maʻamau i nā kaʻa kaʻa hou (ʻo ke kūlana mokuʻāina e like me ka mea i hana ʻia ai kēia lubricant ua hoʻopau lōʻihi ʻia), he mea kūpono ke hoʻohālikelike i nā ʻāpana hana wale no nā ʻaila i hana ʻia ma lalo o ka Nigrol trademark, hoʻohālikelike iā lākou me ka ʻO ka mea hoʻohālikelike kokoke loa, ka momona honua Tad-17.
No ke aha me Tad -17? No ka mea, ua like like ka viscosities o kēia mau mea, a aia ka ʻokoʻa nui i ka laulā a me ka nui o nā mea hoʻohui. E hoʻomanaʻo i ka Soviet nigrol ʻaʻohe mea: e like me GOST 542-50, ua māhele ʻia ka nigrol i "kauwela" a me "hoʻoilo". ʻO ka ʻokoʻa o ka viscosity i hōʻoia wale ʻia e ka ʻenehana o ka distillation aila: i ka "hoʻoilo" nigrol aia kekahi nui o ka tar, i hui pū ʻia me kahi distillate haʻahaʻa-viscosity.
ʻIke ʻia ka ʻokoʻa o nā hiʻohiʻona nui mai ka papa ʻaina:
| ʻO ka pākuhi | ʻO Nigrol e like me GOST 542-50 | ʻO Tad-17 e like me GOST 23652-79 |
| Ka nui, kg / m3 | ʻAʻole i kuhikuhi ʻia | 905 ... 910 |
| ʻO ka'ikehue | 2,7… 4,5 * | ʻAʻole ʻoi aku ma mua o 17,5 |
| wahi ninini, 0С | -5 ....-20 | ʻAʻole ma lalo o -20 |
| wahi uila, 0С | 170 ... 180 | ʻAʻole emi ma lalo o 200 |
| ʻO ka loaʻa ʻana o nā mea hoʻohui | No | he nui na |
* kuhikuhi ʻia ma 0E he degere Engler. E hoʻololi i ka h - nā ʻāpana o ka viscosity kinematic, mm2/s - pono ʻoe e hoʻohana i ke ʻano: 0E = 0,135 hola. ʻO ka laulā viscosity i hōʻike ʻia ma ka pākaukau e pili ana i ka 17…31 mm2/ mai
No laila ma hope o nā mea āpau - nigrol a i ʻole Tad-17: ʻoi aku ka maikaʻi?
Ke koho ʻana i kahi ʻaila ʻaila, pono ʻoe e hoʻolohe ʻaʻole i kona inoa, akā i nā ʻano hana. ʻO ka mea mua, pono lākou e hoʻokō i nā koi o ka maʻamau, a, ʻo ka lua, ʻaʻole pono lākou e pālahalaha nui ma luna o ka laulā. No ka laʻana, inā hōʻike ka mea hana ʻike liʻiliʻi i ka nui o ka ʻaila ʻaila ma ka laulā o 890…910 kg/m3 (ʻaʻole i hele ma mua o nā palena i ʻae ʻia), a laila hiki i kekahi ke kānalua i ka kūpaʻa o nā hōʻailona: aia paha i loaʻa kahi "nigrol" ma o ka hui ʻana o nā ʻāpana i ʻike ʻole ʻia e ka mea kūʻai. Hoʻopili ka hoʻopaʻapaʻa like i ke koena o nā ʻāpana.
ʻO nā mea hana hilinaʻi loa o ka "nigrol" hou i manaʻo ʻia ʻo ia ka inoa inoa FOXY, Agrinol, Oilright.
A ʻo ka hope: e makaʻala i nā huahana, e hoʻoholo ana ma ka lepili, ʻaʻole i hana ʻia e like me GOST 23652-79, akā e like me ka ʻoihana a ʻoi aku ka maikaʻi, nā kikoʻī o ka hale hana!
