Nigrol kana tad 17. Ndeipi iri nani?
Zviri mukati
Kuparadzira maererano
Zvakakodzera kutanga nechokwadi chokuti munguva yedu pfungwa mbiri dziripo: "Nigrol" uye nigrol. Makotesheni akakosha. Muchiitiko chekutanga, tiri kutaura nezvechiratidzo chemafuta egiya, ayo anogadzirwa nemamwe makambani (muRussia, semuenzaniso, ndeye FOXY, Lukoil nevamwe vanoverengeka). Muchikamu chechipiri - pamusoro pekusarudzwa kwemafuta emafuta anowanikwa kubva kune mamwe marudzi emafuta, uye ane pasina kukundikana imwe muzana yezvinhu zvinobudisa resinous, ndicho chikonzero vakawana zita ravo (kubva pashoko rechiLatini rokuti "niger").
Kune classical nigrol, oiri kubva kuminda yeBaku yakashanda seyekutanga mbishi, nepo pakugadzirwa kwemafuta echizvino-zvino emhando iyi, sosi yemidziyo haina kukosha kwakakosha. Nekuda kweizvozvo, mucherechedzo uye kuumbwa kwechero chinhu pfungwa dzakasiyana, saka Nigrol naNigrol vane zvakafanana nzvimbo yekushandiswa zvine musoro (giya maoiri) uye kemikari base - naphthenic mafuta - kubva kunoitwa chigadzirwa. Uye ndizvozvo!
Enzanisa zvakatemwa
Sezvo iyo classic nigrol isingashandiswe mumotokari dzemazuva ano (kunyangwe chiyero chenyika maererano neyakagadzirwa mafuta iyi yakabviswa kare), zvine musoro kuenzanisa maparamendi ekushanda chete emafuta anogadzirwa pasi pechiratidzo cheNigrol, tichienzanisa ne analogue yepedyo, girisi yepasirese Tad- 17.
Sei chaizvo naTad -17? Nokuti viscosities yezvinhu izvi zvinenge zvakafanana, uye musiyano mukuru uri muhuwandu uye huwandu hwezvinowedzera. Yeuka kuti muSoviet nigrol pakanga pasina zvachose: maererano neGOST 542-50, nigrol yakakamurwa kuva "zhizha" uye "chando". Musiyano weviscosity wakave wakasimbiswa chete nehunyanzvi hwemafuta distillation: mu "chando" nigrol pakanga paine imwe tara, iyo yakasanganiswa ne-low-viscosity distillate.
Musiyano muhukuru hunhu huri pachena kubva patafura:
| Parameter | Nigrol maererano neGOST 542-50 | Tad-17 maererano neGOST 23652-79 |
| Density, kg / m3 | Hazvina kutaurwa | 905 ... 910 |
| Viscosity | 2,7…4,5* | Kwete kupfuura 17,5 |
| kudira point, 0С | -5....-20 | Kwete pasi pe -20 |
| flash point, 0С | 170 ... 180 | Kwete pasi pe200 |
| Kuvapo kwezvinowedzera | kwete | kune |
* yakatsanangurwa in 0E madhigirii Engler. Kushandura ku h - zvikamu zve kinematic viscosity, mm2/s - iwe unofanirwa kushandisa fomula: 0E = 0,135h. Iyo viscosity range inoratidzwa mutafura inoenderana ne17…31 mm2/ kubva
Saka mushure mezvose - nigrol kana Tad-17: chii chiri nani?
Paunenge uchisarudza mhando yemafuta egiya, iwe unofanirwa kuterera kwete kune zita rayo, asi kune ayo maitiro ekuita. Kutanga, ivo vanofanirwa kuenderana nezvinodiwa zveyero, uye, chechipiri, havafanirwe kuve nekupararira kwakakura pamusoro pehuwandu. Semuenzaniso, kana mugadziri asingazivikanwe anoratidza kuti density yemafuta egiya iri mukati me890…910 kg/m.3 (iyo yakarongeka isingapfuuri miganhu inobvumirwa), ipapo munhu anogona kusava nechokwadi nekugadzikana kwezviratidzo: zvingangoita kuti "nigrol" yakadaro yakawanikwa nekusanganiswa kwemichina yezvikamu zvakawanda zvisingazivikanwi kumutengi. Iyo caveat yakafanana inoshanda kune mamwe ese ma paramita.
Vagadziri vanonyanya kuvimbika vemazuva ano "nigrol" vanoonekwa sechiratidzo chekutengesa FOXY, Agrinol, Oilright.
Uye pakupedzisira: chenjerera nezvigadzirwa izvo, kutonga nereti, zvinogadzirwa kwete maererano neGOST 23652-79, asi maererano neindasitiri kana, zvakatoipisisa, fekitori yakatarwa!
