Nigrol noma tad 17. Yikuphi okungcono?
Okuqukethwe
Hlakaza ngokwemibandela
Kuhle ukuqala ngeqiniso lokuthi esikhathini sethu kunemiqondo emibili: "Nigrol" ne-nigrol. Izingcaphuno zibalulekile. Esimweni sokuqala, sikhuluma ngophawu lokuthengisa lwamafutha egiya, akhiqizwa izinkampani ezithile (eRussia, isibonelo, i-FOXY, i-Lukoil nezinye eziningi). Okwesibili - mayelana nokuqokwa okujwayelekile kwamafutha atholakala ezinhlotsheni ezithile zamafutha, futhi aqukethe ngaphandle kokuhluleka amaphesenti athile ezinto ezikhishwa inhlaka, yingakho bathola igama labo (kusuka egameni lesiLatini elithi "niger").
Ku-nigrol yakudala, uwoyela ovela ezinsimini ze-Baku wasebenza njengezinto zokuqala zokusetshenziswa, kuyilapho ukukhiqizwa kwezinto zokugcoba zanamuhla zalolu phawu, umthombo wezinto ezingavuthiwe awubalulekile kangako. Ngakho-ke, uphawu lokuhweba kanye nokwakheka kwanoma iyiphi into ebonakalayo imiqondo ehlukene, ngakho-ke i-Nigrol ne-Nigrol bafana nendawo yokusetshenziswa okunengqondo (amafutha egiya) kanye nesisekelo samakhemikhali - amafutha e-naphthenic - lapho umkhiqizo wenziwa khona. Futhi yilokho!
Qhathanisa imininingwane
Njengoba i-nigrol yakudala ingasetshenziswa ezimotweni zesimanje (ngisho nezinga lombuso ngokusho ukuthi le nto yokuthambisa yaqedwa kudala), kunengqondo ukuqhathanisa amapharamitha okusebenza kuphela kumafutha akhiqizwa ngaphansi kophawu lwentengiso lwe-Nigrol, uwaqhathanise nowoyela. i-analogue eseduze, igrisi yendawo yonke i-Tad- 17.
Kungani ngempela nge-Tad -17? Ngoba ama-viscosities alezi zinto ayafana, futhi umehluko omkhulu usebangeni kanye nenani lezithasiselo. Khumbula ukuthi e-nigrol yaseSoviet kwakungekho nhlobo: ngokusho kwe-GOST 542-50, i-nigrol yahlukaniswa ngokuthi "ihlobo" kanye "nobusika". Umehluko ku-viscosity waqinisekiswa kuphela ngobuchwepheshe bokukhipha amafutha: "ebusika" i-nigrol kwakukhona inani elithile letiyela, elixutshwe ne-distillate ephansi ye-viscosity.
Umehluko ezicini eziyinhloko usobala etafuleni:
| Ipharamitha | Nigrol ngokuvumelana GOST 542-50 | I-Tad-17 ngokuhambisana ne-GOST 23652-79 |
| Ukuminyana, kg/m3 | Akucacisiwe | 905… 910 |
| Ukungabi nabulungisa | 2,7… 4,5 * | Akukho ngaphezu kuka-17,5 |
| thela iphuzu, 0С | -5 ....-20 | Hhayi ngaphansi kuka -20 |
| iphoyinti elikhanyayo, 0С | 170… 180 | Hhayi ngaphansi kuka-200 |
| Ukuba khona kwezithasiselo | No | Zikhona |
*kucaciswe ku 0U-E yiziqu ze-Engler. Ukuguqula ku-h - amayunithi we-kinematic viscosity, mm2/s - kufanele usebenzise ifomula: 0E = 0,135h. Ububanzi be-viscosity obukhonjiswe kuthebula buhambisana cishe no-17…31 mm2/ kusuka
Ngakho emva kwakho konke - i-nigrol noma i-Tad-17: yikuphi okungcono?
Lapho ukhetha uhlobo lwamafutha egiya, akufanele unake igama lalo, kodwa izici zokusebenza. Okokuqala, kufanele bahambisane nezidingo zezinga, futhi, okwesibili, akumele babe nokusabalala okukhulu phezu kobubanzi. Isibonelo, uma umkhiqizi owaziwa kancane ekhombisa ukuthi ukuminyana kwamafutha egiya kuphakathi kuka-890…910 kg/m.3 (okuyinto ngokusemthethweni engahambi ngaphezu kwemingcele evunyelwe), khona-ke umuntu angangabaza ukuzinza kwezinkomba: kungenzeka ukuthi "i-nigrol" enjalo yatholwa ngokuxuba komshini kwezingxenye eziningana ezingaziwa kumthengi. Isixwayiso esifanayo sisebenza kuwo wonke amanye amapharamitha.
Abakhiqizi abanokwethenjelwa kakhulu be "nigrol" yesimanje babhekwa njengezimpawu zokuthengisa FOXY, Agrinol, Oilright.
Futhi ekugcineni: qaphela ngemikhiqizo, ukwahlulela ngelebula, akhiqizwa hhayi ngokusho kwe-GOST 23652-79, kodwa ngokusho kwemboni noma, okubi nakakhulu, ukucaciswa kwefekthri!
