Ndedzipi ongororo dzinoda kuitwa kana uchishandisa bhitumini yakagadziridzwa?
Midziyo mizhinji ichave nematambudziko madiki kana uchiishandisa. Kuti uishandise zvakajairika, basa rekuongorora zuva nezuva haridzivisiki. Ngatitarisei izvo zvakagadziridzwa bhitumini (kuumbwa: asphaltene uye resin) midziyo inoda kuita muhupenyu hwezuva nezuva. Ndeapi mabasa ekuongorora?
Tinofanira kugara tichiongorora iyo yakagadziridzwa emulsifier yeyakagadziridzwa bhitumini chirimwa. Kana iyo emulsifier yakashandiswa kwenguva yakareba uye mukaha pakati peemulsified bitumen colloid mill ichave yakakura, saka tinofanira kuigadzirisa panguva ino kuti tienderere mberi nekugadzirwa. Uyu kuenzanisa Mubvunzo uri nyore: Yakagadziridzwa bhitumeni chirimwa ndechekuwedzera ekunze admixtures (modhifita) senge rabha, resin, yakakwira molecular polymers, yakatsetseka yakatsetseka rabha poda kana mamwe mafirita, kana kutora matanho akadai sekupfava oxidation processing yebhitumini kugadzira iyo. bhitumini Kana bitumeni binder yakagadzirwa nekuvandudza kushanda kwebhitumini musanganiswa.
Ongorora dambudziko rema modifiers. Kazhinji, huwandu hwema modifiers akawedzerwa hunofanirwa kunge huri munzvimbo. Paunenge uchiwedzera, iyo pH kukosha inofanira kugadziridzwa zvichienderana nemhando yemvura inoshandiswa. Nyaya iyi inoda kuti vashandi vaongorore. Zvinogoneka zvikonzero zvinokonzereswa nematambudziko neakagadziridzwa bhitumini (kuumbwa: asphaltene uye resin) chirimwa pachayo, nekuti yakajairika bhitumeni inewo kupatsanurwa kwakasiyana. Paunenge uchigadzira bhitumini yakagadziridzwa, kutarisisa kunofanirwa kubhadharwa kune iyo mbishi inoshandiswa ndiyo inodiwa. Ordinary bitumen and guaranteed quality.
Iyo yakagadziridzwa bhitumeni inogadzirwa neyakagadziridzwa bhitumeni midziyo, kune rumwe rutivi, inochengeta kana kuwedzera kubatanidzwa, plastiki uye fluidity yebhitumeni yepakutanga, kune rumwe rutivi, inovandudza kugadzikana kwekushisa (tsananguro: yakagadzikana uye yakagadzikana; hapana shanduko) ye bhitumeni uye Elasticity, iyo inogona kuzadzisa chinangwa chekuvandudza kushanda kwebhitumini mugwagwa.
Pamusoro pezvo, bhitumini yakagadziridzwa (kuumbwa: asphaltene neresin) inotora nzira inofambira mberi uye yesainzi yekugadzira uye inogona kuramba ichiburitsa yakapedzwa polymer yakagadziridzwa bhitumeni inosvika makumi matatu matani/awa. Iyo zvakare inoenderera inoenderera muchina ine hombe imwe chete yekugadzira muchina. Sexually modified emulsified bitumen midziyo yakakodzera kugadzirwa kweakasiyana madiki uye epakati-saizi mabhechi eakagadziridzwa emulsified bhitumeni michina. Inogona kusangana nezvinodiwa zveakasiyana mamiriro ekushandisa uye kugadzira yakagadziridzwa bhitumini chirimwa chine yakakwirira mugwagwa kuita uye yakagadzikana (tsananguro: yakagadzikana uye yakagadzikana; hapana shanduko).
