Diziri inoomesa nechando patembiricha yakadini?
Zviri mukati
Chii chinonzi waxing, uye nei chakaipa kumotokari yedhiziri?
Mawakisi edhiziri, anogara achiwanikwa mumafuta edhiziri, mahydrocarbon akareba-cheni anowanzoita kupenya pakudziya kwakaderera. Aya mahwendefa ecrystalline anovhara mafirita mumaketani echokwadi e "wax". Iyo yakasanganiswa refu cheni ma hydrocarbons anowedzera zvinoshamisa viscosity yemafuta edhiziri, iyo yakaipa kune zvese injini uye pombi yemafuta. Kuvapo kwemvura muhuwandu hwakakwana kunokonzera rimwe dambudziko - kuumbwa kwemakristasi echando. Izvi zvinoitika pachando chemafuta edhiziri. Dambudziko nderekuti: a) mvura hainyungudika mune chero mvura yemahydrocarbon; b) makristasi aya pane dzimwe tembiricha atove chinhu chakasimba, mukusiyana neparafini, iyo ichiri mvura.
Muzviitiko zvese izvi, mafuta edhiziri anozotanga kuyerera zvakare chete kana ichipisa pamusoro petembiricha yecrystallization.
Dambudziko, sezvazvakaita, rinogona kugadziriswa nekuwedzera imwe chiyero (kubva pa7 kusvika ku10%) yebiodiesel kune dizeli mafuta. Nekudaro, chekutanga, biodiesel mafuta inodhura, uye chechipiri, izvi dzimwe nguva zvinoumba chinhu chakakora chinokonzera kupupuma kwemafuta edhiziri asina zvimwe zvinowedzera.
Kusiyana neparafini (apo makristasi emamorekuru akasanganiswa akaparadzana nekupisa kwakakwira), musanganiswa wemafuta edhiziri nebiodiesel unova nemakore uye haakurumidzi kudzoka kuita mafuta akajairwa.
Turbid suspension, iyo inoitika panguva yekugadzira waxing, inovhara mafirita, ayo anoremedza zvakanyanya kushanda kwepombi yemafuta. Nekuda kweizvozvo, mikaha muzvikamu zvinofamba inorasika uye maitiro akaoma ekukwesha anotanga. Sezvo tembiricha uye kumanikidza kwakakwira, iyo exfoliated simbi particles pane kukurumidza kushanduka kuita simbi hupfu, iyo inotanga kugwangana uye ipapo sinter. Uye pombi yapera.
Kuti uone kuti izvi hazviitike, zvinodikanwa kushandisa zvakaringana zvinowedzera kune biodiesel musanganiswa. Mukuwedzera, hapafaniri kuva nemvura mumafuta edhiziri, iyo inovharawo mafiritsi.
Pane musiyano here pakati pe "winter diesel" ne "winter diesel"?
Pane. Muchiitiko chekutanga, mafuta edhiziri anosanganiswa neparafini, mune yechipiri, antigel inowedzerwa kune yakajairika mafuta edhiziri. Zviteshi zvepeturu zvizhinji zvinopa dhiziri remuchando panzvimbo pedhiziri remuchando nekuti rakachipa. Vamwe vane hungwaru uye vanopa ese marudzi ese kuti vasiye vatengi vazvisarudzire. Kumotokari itsva, dhiziri yechando ine zvinowedzerwa zvakakodzera inosarudzwa.
Uye zvakadini nebiodiesel? Kuvapo kwayo kunoda shanduko muhunyanzvi hwekurapa mafuta, sezvo gelation point inosiyana kubva kune mumwe. Nokudaro, biodiesel ichaita zvakasiyana nemafuta emagetsi. Biodiesel, sedhiziri, gels mukutonhora kwemamiriro ekunze, asi iyo chaiyo yekugadzira gel tembiricha inotsamira pane izvo biodiesel yakagadzirwa kubva. Diesel oiri inoshanduka kuita gel patembiricha imwe chete panotanga kukwizwa mafuta kana mafuta aishandiswa kugadzira mafuta.
Inotonhora nzvimbo yezhizha dhiziri mafuta
Zvakaoma kunyatso verenga rudzi urwu nekuti zvakawanda zvinosiyana zvinouya. Nekudaro, maviri akakosha tembiricha anozivikanwa:
- Gore rekuti wakisi yeparafini ichangotanga kubuda mumafuta.
- Iyo yekudira iyo dhiziri ine gel rakawanda mukati mayo zvekuti haichayerera. Iyi poindi kazhinji iri pazasi pegore rehuni.
Yezhizha mafuta edhiziri, tembiricha yekutanga inoenderana nerenji -4 ... -6ºC, uye wechipiri -10 ... -12ºC (kutora nguva dzose kunze kwekushisa kwemhepo). Kunyanya, tembiricha idzi dzinotemerwa mumarabhoritari, uko mamwe maitiro emuviri uye emagetsi emafuta anotariswa zvakare.
