atural bitumen: Petroleum inosvinwa negoko renyika kwenguva yakareba muzvisikwa uye inosangana nemhepo uye hunyoro. Mafuta ayo akareruka anobuda zvishoma nezvishoma, uye bhitumeni yepetroleum inoumbwa nekudzikamisa uye oxidation inowanzosanganiswa neimwe chikamu chezvicherwa. Bhitumeni yechisikigo inogona kukamurwa kuita bhitumeni yegungwa, bhitumeni yedombo, bhitumini yepasi pemvura, shale yemafuta, nezvimwe zvinoenderana nenharaunda iyo inoumbwa.
Bhitumeni yedombo chinhu chakaita sebhitumini chinobva mupetroleum yekare ichipinda mumitswe yematombo, uye mushure memazana emamiriyoni emakore ekuisa, shanduko, adsorption, uye fusion, pasi pezvakasanganiswa zvinokonzeresa kupisa simba, kudzvanywa, oxidation, catalysts, mabhakitiriya, nezvimwewo.

bhitumini yedombo yakagadziridzwa inoshandisa bhitumini yedombo sechigadziriso uye inosanganiswa nebhitumeni yematrix zvichienderana nekumwe kusanganiswa reshiyo. Bhitumini yakagadziridzwa inogadzirwa kuburikidza nemaitiro akadai sekusanganisa, kuveura, nekusimudzira. Inonzi NMB.
Rock bitumen modified bitumen musanganiswa unogadzirwa ne "wet" process based on "rock bitumen modified bitumen" kana musanganiswa unogadzirwa ne "dry" process based on "rock bitumen modification".
"Dry method" process "Dry method" process inoreva kuti mushure mekudira zvicherwa mupoto yekusanganisa, rock bitumen modifier inowedzerwa mupoto yekusanganisa uye yakasanganiswa nemamineral materials yakaoma kwenguva yakati rebei, yobva yapfapfaidza mukati. iyo matrix bhitumeni yekunyorovesa Bitumen musanganiswa maitiro.
“Wet method” process “Wet method” process zvinoreva kuti bhitumini yedombo uye bhitumene yepasi pane imwe tembiricha zvinotanga zvasanganiswa, zvogerwa, zvoitwa bhitumini yedombo yakapedzwa yakagadziridzwa, yozopfapfaidzwa mupoto yekusanganisa kuti isanganiswe nayo. the ore. Bitumen musanganiswa wekusanganisa maitiro.
