Mafuta kukhuthala

Mafuta - masoka wochuluka madzi amene ali ndi chuma cha flammability ndi zizindikiro osakaniza zovuta mankhwala hydrocarbon ndi ena zinthu organic.

Ngati ife kulankhula za mtundu, mafuta akhoza kukhala pabuka-bulauni kapena lakuda. Palinso anthu a mitundu mafuta chikasu wobiriwira, kapena alibe mtundu ambiri.

Mafuta, monga ulamuliro, ali angapo achilendo fungo. nkhokwe zake zimapezeka miyala nyanja ya Earth.

Pakali pano, mafuta - ndi mchere wofunika kwambiri.

Nkosafuna kunena kuti zochitika zokhudza m'zigawo ndi kuyenga mafuta, nthawizonse wakhala, ndi kudzakhala kopindulitsa. Chinthu chofunika kwambiri mu nkhani iyi ndi mkulu chiyeneretso cha ogwira ntchito, luso lawo, luso ndi nzeru zofunika bungwe moyenera ntchito.

Kulinganiza zinthu kumtunda ndipo pambuyo pake, ndikofunikira kukhala bwino ndi katundu wa thunthu.

Kuphunzira katundu izi chinkhoswe mu sayansi, wotchedwa Mafuta ndi gasi nthaka. Kuwonjezera pa katundu wa mafuta, sayansi maphunziro ndi kapangidwe ka mafuta ndi gasi madipoziti. kudziwa izi zonse kuthandiza kupanga zomveka dongosolo kupanga mafuta, komanso kudziwa kukula kwa miyala ya mchere izi.

Mmodzi wa katundu zofunika ndi kukhuthala mafuta. katundu lisinthike osiyanasiyana m'malo lalikulu. Izi zikhoza kukhala millimeters 1,98 lalikulu pa wachiwiri, kapena 265, millimeters lalikulu 90 pa nthawi unit.

Chiwerengerochi zikusonyeza kuti mitundu yosiyanasiyana ya mafuta kuti akupangidwa m'dziko lathu.

Kukhuthala mafuta zimadalira kapangidwe kake fractional, komanso kutentha. chitsanzo akhoza kukhala wolemekezeka: apamwamba kutentha, m'pamenenso tuzigawo twa mafuta chitadutsa, m'munsi kukhuthala zace.

The kukhuthala mafuta, pamodzi ndi kulemera maselo, kachulukidwe, crystallization kutentha, mphamvu kutentha, madutsidwe magetsi, pophulikira ndi chuma thupi.

Ngati ife tikuyang'ana pa mabuku, zimaonekeratu kuti pali gulu lapadera la mafuta kukhuthala.

Childs, zili sulfure mafuta akhoza kukhala lokoma, wowawasa, ndi wowawasa.

Ngati chinthu zimagawidwa ndi ochititsa tuzigawo twa amene wiritsani pa kutentha 3500 madigiri Celsius, mafuta akhoza kugawidwa mu mitundu monga T1, T2 ndi T3. T1 mtundu kumafuna angapo tuzigawo twa peresenti zosakwana 45. Mtundu T2 akusonyeza pamaso pa 30 - 44 peresenti ya tuzigawo twa ndi T3 mtundu limasonyeza kuti kachigawo ali peresenti zosakwana 30.

Ngati ife kulankhula za zili mafuta, mafuta akhoza kugawidwa mu mitundu ya M1, ngati mafuta lili 25 peresenti kapena kuposa, komanso m2, ngati peresenti zosakwana 25 ali mafuta.

Pa khalidwe la Mafuta mafuta lagawidwa mtundu I1, ngati kukhuthala index kuposa 85, ndipo I2 mtundu, ngati index zimasiyanasiyana 40 85.

classifications zimenezi pamodzi ndi mzake, amene adzapanga cipher ndondomeko gulu la mankhwala.

Nthawi zambiri m'pofunika kuchepetsa kukhuthala mafuta. Kuti tichite zimenezi, pali njira zingapo. Ena mwa iwo ndi mkangano pa kutentha, ndi emulsion mafuta mu sing'anga amadzimadzi ndi ntchito emulsifiers wapadera.

N'zothekanso zimakhudza zosiyanasiyana madzi cheza mu atomu kapena mafuta ndondomeko, ntchito akupanga kugwedera, iwo ayenera kukhala mwamphamvu kwambiri.

Nthawi zambiri, ngakhale zosiyanasiyana zimenezi pogwiritsa ntchito kutentha, pamene ntchito boilers yotulutsa kutentha pa kuyaka wa malasha, gasi kapena mafuta, lomwe linachokera ku payipi chomwecho.

Munthu angathe kugwiritsa ntchito kutentha anamasulidwa mu ndondomeko ya ikukoka pa ikukoka mafuta mu siteshoni wapadera, kapena kuti kutenthetsa mafuta mwachindunji.
