Ndeupi musiyano pakati pemafuta mashanu ebhesi?

Mafuta ekuzora anoumbwa nemafuta ekutanga uye ekuwedzera, mafuta ekutanga akakamurwa kuita marudzi mashanu, zvichiteerana ⅠⅡⅢⅣⅤ kirasi base oiri, Bang master kukuudza nezve aya marudzi mashanu emafuta epasi akasiyana.

Kirasi I base mafuta

Maitiro ekugadzira echinyakare anonyungudutsa ekunatsa mineral oiri, Kirasi I base oiri yakavakirwa pakuita kwemuviri, haishandure chimiro chehydrocarbons, kuita kwacho kunoenderana nemhando yezvigadzirwa, kuita kwacho kwakawanda, ndiko kwakachipa. base mafuta pamusika.

Kirasi II base mafuta

Hydrocracking mineral oil, Kirasi II base oiri inogadzirwa neyakasanganiswa maitiro (solvent process yakasanganiswa nehydrogenation process), kunyanya nemakemikari process, inogona kushandura yekutanga hydrocarbon chimiro. Naizvozvo, Kirasi II base oiri ine shoma shoma, yakakwira yeakazara mahydrocarbons, yakanaka kugadzikana kwekupisa uye kushomeka kweokisijeni, tembiricha yakaderera uye soot dispersion performance zviri nani pane Kirasi I base mafuta.

Kirasi III base mafuta

Yakadzika hydroisomerization dewaxing base oiri, Kirasi III base oiri ndiko kudiwa kwekudzikisa mbishi zvinhu zvine yakakwira hydrogen, ine yakazara hydrogenation maitiro, ari eiyo high viscosity index hydrogenation base mafuta, anozivikanwawo seasina kujairika base oiri (UCBO), akawandisa kupfuura. kirasi I base mafuta uye Kirasi II base mafuta mukuita.

Kirasi IV base mafuta

Polyalphaolefin synthetic mafuta, inozivikanwawo sePAO base oiri. Iyo inowanzoshandiswa nzira dzekugadzira yekirasi IV base mafuta iparafini yekupwanya nzira uye ethylene polymerization nzira, uye mafuta epasi anoumbwa nemacromolecules anonatswa kuburikidza neakaoma kuita kemikari. Mamorekuru akarongwa zvakanaka, oiri ndeyemhando yakanaka, ine yakakwira viscosity index, yakanakisa oxidation kuramba uye kugadzikana kwemafuta, uye kuderera kuderera.

Kirasi V base mafuta

Kirasi V base oiri, kuwedzera kune kirasi I-IV base oiri mamwe maoiri ekugadzira, anosanganisira synthetic hydrocarbons, esters, silicone mafuta uye mamwe mafuta emiriwo, pamwe chete anonzi Class V base mafuta.
