Ibhitumene, eyona nto ibalulekileyo ekuthinteleni amanzi ngebhitumene, lulwelo lwe-hydrocarbon olufumaneka kwiindawo ezifana nesanti yeoyile kunye namachibi e-pitch okanye olufunyenwe ngokuhluzwa kweoyile ekrwada kwiindawo zokuhluza. Ngexesha lenkqubo yokuhluza njengoko izinto ezikhaphukhaphu zinyuka ziye phezulu, izinto ezinzima, kuquka nebhitumene, ziwela ezantsi kwekholam.

Emva kokususa iinxalenye ezikhaphukhaphu ezifana negesi yepetroleum engamanzi, ipetroli, kunye nedizili kwioyile ekrwada ngexesha lenkqubo yokucoca, i-residual component ibizwa ngokuba yi-bitumen. Udidi lwe-bitumen lunokutshintsha ukuya kuthi ga kwinani lezinto eziguquguqukayo ezisele kwi-distilled bitumen.

I-bitumen ingasetyenziswa njengezinto eziluhlaza okanye njengomxube kuxhomekeke kwiindawo ezisetyenziswayo. Ingasetyenziswa njengesixhobo sokubopha kwi-asphalt kwiindlela, kwiindlela zeenqwelo moya, kwiindawo zokupaka, nakwiindlela zeenyawo. Ikwasetyenziswa njengomxube kwicandelo lezakhiwo nezakhiwo ukusuka kwisiseko ukuya eluphahleni ukuze ibonelele ngomgangatho ogqwesileyo wokuthintela ukungenwa kwamanzi.

Ibhitumen ingatshintshwa ngeepolymers ukuphucula ukusebenza kwayo kwaye isetyenziswe njengeemveliso ezahlukeneyo kwishishini lokwakha. Isebenza njengeyona nto iphambiliukuthintela amanziizixhobo ezikwiindlela ze-sealants, i-mastics, i-glue, i-coating njl.njl.

Kutheni iBitumen Idumile Kwicandelo Lokuthintela Ukungenwa Ngamanzi?

Okokuqala, i-bitumen inenkqubo yezoqoqosho. I-bitumen, ehlala ihleli emva kwenkqubo yokucocwa kweoyile eluhlaza, yimveliso ephumayo Xa iimveliso eziphambili ezifana nepetroli, idizili, amafutha ane-octane eninzi kunye nepetroli zicociwe, i-bitumen ishiywa ngasemva.

Ngaphandle koko, i-bitumen yimveliso eguquguqukayo. Ibonisa iindlela zokuziphatha ze-viscoelastic kunye ne-thermoplastic. I-bitumen ineendlela zokuziphatha eziqinileyo nezithambileyo kuxhomekeke kubushushu kunye nexesha lokulayisha. Xa kushushu kakhulu okanye kumaxesha okulayisha amade, i-bitumen iziphatha njengezinto ezithambileyo. Xa kushushu kakhulu okanye xa kushushu kakhulu i-bitumen iziphatha njenge-elastic solid.

Iqondo lokunyibilika kwebhitumen aliphezulu kakhulu kangangokuba inokunyibilika lula ngexesha lokusetyenziswa. Ibhitumen inamathela kakhulu, nto leyo egcina izinto zihlangene kakuhle. Zonke ezi mpawu zingqina ukuba ukuthintela amanzi ngebhitumen sesinye sezona zisombululo zilula kwiindawo ezisetyenziswayo.

Zithini iimveliso zeBitumen zeBaumerk kunye neengenelo zazo?

Izinto zokuthintela amanzi ngebhitumen zineendawo ezahlukeneyo zokusetyenziswa. Ngenxa yeIBaumerkUngasebenzisa iintlobo ezahlukeneyo zeemveliso zokuthintela amanzi ngebhitumen kwiimfuno ezahlukeneyo. Izixhobo zokuthintela amanzi ngebhitumen kuluhlu lweemveliso zeBaumerk, eziyimveliso enye okanye ezimbini ezineemilo eziqinileyo nezilulwelo, zineengenelo ezininzi.

Umzekelo, i-polyurethane kunye neemveliso eziguqulwe ngerabha ziyafumaneka kwiindawo ezahlukeneyo zokusetyenziswa ukuze zibonelele ngeempawu ezahlukeneyo zemveliso. Kwakhona, iifom ze-membrane, i-coating, i-mastic kunye ne-sealant ziyafumaneka. Iimpawu zemveliso ngokubanzi zisebenza ngokunamathela kakhulu, zithambile, zisebenza ixesha elide kwaye zihlala ixesha elide, zixhathisa ukurhawuzelelwa okuphezulu, kulula ukuzisebenzisa kwaye zinoqoqosho.

Ukuze ufunde okungakumbi ngezinye izinto zokuthintela amanzi kunye nokuthintela amanzi ngebhitumen, ungajonga umxholo wethu onesihloko esithiZithini Izinto Zokuthintela Ukungangeni Manzi: Zonke Iintlobo, Ukusetyenziswa, kunye Neempawu.
