Ibhitumene, eyona nxalenye ibalulekileyo yokuthintela ukungenwa manzi kwebhitumene, yenziwa yihydrocarbon efumaneka kwiidipozithi ezifana nesanti yeoli namachibi epitch okanye efunyanwa ngokuxutywa kweoli ekrwada kwiindawo zokuhluza. Ngexesha lenkqubo ye-distillation njengoko amacandelo alula aphakama ukuya phezulu, amacandelo anzima, kuquka i-bitumen, awela phantsi kwekholomu.

Emva kokususa amaqhezu alula njengerhasi yepetroleum elulwelo, i-petroli kunye nedizili kwi-oyile ekrwada ngexesha lenkqubo yokucokisa, icandelo elishiyekileyo libizwa ngokuba yibhitumene. Umgangatho webhitumene unokutshintsha ukuya kutsho kubungakanani bezinto eziguquguqukayo eziseleyo kwibhitumene ediyitiweyo.

Ibhitumene ingasetyenziswa njengento ekrwada okanye njengomxube ngokuxhomekeke kwindawo ekugalelwa kuyo. Ingasetyenziswa njenge-binder kwi-asphalt yeendlela, iinqwelo-moya, iindawo zokupaka, iindlela zeenyawo. Ikwasetyenziswa njengomxube kwicandelo lolwakhiwo kunye nolwakhiwo ukusuka kwigumbi elingaphantsi ukuya eluphahleni ukubonelela ngomgangatho ogqwesileyo wokuthintela amanzi.

Ibhitumene inokuguqulwa ngeepolymers ukuphucula ukusebenza kwayo kunye nokusetyenziswa njengeendlela ezahlukeneyo zemveliso kwishishini lokwakha. Isebenza njengenxalenye ephambili yeukuthintela amanziizixhobo kwiifom ze-sealants, imastics, i-adhesive, i-coating njl.

Kutheni le nto ibhitumene idumile kwiCandelo lokuThintela amanzi?

Okokuqala, ibhitumene inenkqubo yezoqoqosho. Ibhitumene, ehlala emva kwenkqubo ye-oyile ekrwada yokuchithwa kwe-distillation, yimveliso yemveliso Xa iimveliso eziphambili ezifana nepetroli, idizili, i-octane ephezulu kunye nepetroli zicokiswa, ibhitumene ishiywe ngasemva.

Ngaphandle koko, ibhitumene yimveliso eguquguqukayo. Ibonisa ukuziphatha kwe-viscoelastic kunye ne-thermoplastic. Ibhitumene inazo zombini iimpawu ze-viscous kunye ne-elastic ngokuxhomekeka kwiqondo lobushushu kunye nexesha lokulayisha. Kubushushu obuphezulu okanye ngamaxesha okulayisha amade, ibhitumene iziphatha njengesixhobo esibonakalayo. Kumaqondo obushushu aphantsi okanye kwimowudi yokulayisha ngokukhawuleza ibhitumene iziphatha njengoqina olulastiki.

I-melting point ye-bitumen ayikho phezulu kangangokuthi inokuncibilika ngokulula ngexesha lokufaka isicelo. Ibhitumene inendalo encamathelayo kakhulu, egcina izixhobo kunye ngamandla. Zonke ezi mpawu zibonisa ukuba i-bitumen yokungangeni kwamanzi yenye yezona zisombululo ezifanelekileyo ukuya kwiindawo zokusetyenziswa.

Ziziphi iiMveliso zeBitumen zeBaumerk kunye nezinto eziluncedo zazo?

Izinto zokukhusela amanzi ze-bitumen zineendawo ezininzi zesicelo. Enkosi KuBaumerk, ungasebenzisa iintlobo ezahlukeneyo zeemveliso zokuthintela amanzi kwibhitumene kwiimfuno ezahlukeneyo. Izinto ze-bitumen zokukhusela amanzi kwiimveliso ze-Baumerk, eziyimveliso enye okanye ezimbini zecandelo kunye neefom eziqinileyo kunye ne-liquid, zineenzuzo ezininzi.

Ngokomzekelo, i-polyurethane kunye neemveliso eziguqulwe ngerabha ziyafumaneka kwiindawo ezahlukeneyo zesicelo sokubonelela ngeempawu ezahlukeneyo zemveliso. Kwakhona, i-membrane, i-coating, i-mastic kunye ne-sealant iifom ziyafumaneka. Iimpawu zemveliso ngokubanzi zenza ukusebenza kokuncamatheliswa okuphezulu, ukuqina, ukusebenza ixesha elide kunye nokuqina, ukuxhathisa okuphezulu kwe-abrasion, ukusebenziseka ngokulula kunye noqoqosho.

Ukufunda ngakumbi malunga nezinye izinto zokuthintela amanzi kunye nebhitumene yokuthintela amanzi, unokujonga umxholo wethu onesihloko esithiZiziphi izixhobo zokuThintela amanzi: zonke iintlobo, ukusetyenziswa kunye neempawu.
