Yini i-asphalt? Umehluko Osemqoka phakathi kwePetroleum Asphalt kanye ne-Coal Tar Pitch

I-Asphalt iyinto emnyama, ebonakalayo ethathwe ku-oyili ongahluziwe (i-petroleum asphalt) noma i-coal tar (i-coal tartch pitch), isetshenziswa kabanzi ku-asphalt ngopende wokuvimbela amanzi nokugqwala.
Umehluko Osemqoka
Umthombo:
I-Petroleum asphalt: icwengeke emafutheni angahluziwe, ubuthi obuphansi, ilungele imigwaqo nopende asphalt.
I-Coal Tar Pitch: Byprodlict of Coal Processing, iqukethe ama-pahs, asetshenziswa kupende we-asphalt wezimboni wokumelana kwamakhemikhali.
Izakhiwo:
Asphalt e-petroleum amelana nesimo sezulu; I-Coal Tar Pitch idlula ekunamathisweni ngopende we-asphalt ngezimo ezinzima.
Sebenzisa:
Upende we-asphalt osuselwa ku-petroleum uvamile ophahleni nasemigwaqweni; Amalahle entengo ahlukile evikela amapayipi.
Kungani-asphalt penda?
I-Asphalt Paint ihlanganisa ukuqina nokuvikelwa kwe-UV, ilungele izindawo eziphakeme zethrafikhi.
