Ukunyibilika kunye neendawo ezibilayo ze-Asphalt: Kutheni le nto iphazamisa amaqondo obushushu aphezulu? ​​

I-Asphalt, umxube ontsonkothileyo we-hydrocarbons, ingena kwindawo ebukhali eqinileyo ngenxa yokuqulunqa kwayo. Endaweni yoko, ibonisa uluhlu lwendawo yokuthambisa (ngokwesiqhelo i-40-60 ° C kwiPetrolem), ngaphaya koko kuthunyelwa kwi-qinile kulwelo lwe-viscous. Le ndlela yokuziphatha isuka kwisakhiwo sayo se-collodal:

I-Molecular Dynamics: Kwiqondo lobushushu eliphakamileyo, iqhezu leoyile ye-oyile (i-maltenes) ngaphakathi kwe-Asphalt iba ngamanzi, buthathaka i-asphaltene matrix. Oku kunciphisa amandla amanye amazwe, kubangela ukuthambisa.
Imvakalelo yobushushu: i-vissosity ye-asphalt ihla ngokuvakalayo ubushushu. Umzekelo, nge-60 ° C, i-asphalt esemgangathweni inokuphulukana ne-90% yokuqina kwayo, ekhokelela ekuthandeni imithwalo yendlela. I-asphalts eguqulweyo (i.G., iindidi zemodyuli eziphezulu) Kuxhathise le nto ngenethiwekhi yePolymer ekwazi ukuzinzisa isakhiwo ukuya kuthi ga kwi-70 ° C okanye ngaphezulu.
Ukubila nokulahla:
I-Asphalt iphosa ngaphambi kokufikelela kwindawo yokuthengisa inyani (ngaphantsi kwe-470 ° C), ukukhulula igesi enetyhefu njenge-bedzene. Ngenxa yoko, indawo yokubila ayifaneleke kakhulu kunendawo eFlash (~ 204 ° 2), ephawula umngcipheko wokudibana ngexesha lokufudumeza.

Iziphumo eziSebenzayo:

Ukusilela kwendlela: Amaqondo obushushu ehlobo okungaphezulu kwe-50 ° C ukuba i-asphalt ye-asphalt, ibangela iingxaki esisisigxina njenge-rut.
Isisombululo: Sebenzisa ii-Binders eziguquliweyo
Kwisishwankathelo, i-asphalt ithambisa ngenxa yokuqhekeka kwe-colloidal kunye nokungenisa i-thermal, kunyanzelisa izinto ezinokwenzela izinto zokwenza.
