Izitshalo zokuxuba i-asphalt zizokhiqiza uthuli oluningi kanye negesi yokukhipha eyingozi ngesikhathi sokwakhiwa. Ukuze kuncishiswe umonakalo odalwa yilokhu kungcola, okokusebenza okufanelekile kokususa uthuli kuvame ukulungiselelwa ukwelashwa. Njengamanje, izinhlobo ezimbili zamathuluzi okususa uthuli, okuhlanganisa abaqoqi uthuli lwe-cyclone kanye nabaqoqi bezikhwama, ngokuvamile zisetshenziselwa ukuqoqa ukungcola ngangokunokwenzeka ukuze kuncishiswe ukungcola kanye nokuhlangabezana nezindinganiso zemithetho yokuvikela imvelo.
Kodwa-ke, kule nqubo, imishini ekhethiwe yokususa uthuli kufanele ihlangabezane nezidingo ezithile. Ikakhulukazi ekukhethweni kwezinto zokuhlunga, ngoba ngemva kwesikhathi sokusetshenziswa kwemishini yezitshalo zokuxuba i-asphalt kanye nabaqoqi bothuli besikhwama somshini, izinto zokuhlunga zizolimala ngenxa yezizathu ezithile futhi zidinga ukulungiswa noma ukushintshwa. Ngakho-ke, ukuthi iyiphi impahla yokuhlunga okufanele uyikhethe kuwumbuzo okufanele ucabange ngawo. Indlela evamile ukukhetha ngokuvumelana nezinhlinzeko nezimfuneko zemanuwali yeziqondiso zemishini noma imanuwali yokulungisa, kodwa namanje ayilungile.

Ngokuvamile, kunezinhlobo eziningi zezinto zokusetshenziswa ezisetshenziselwa ukuhlunga ukuze kuhlangatshezwane nezidingo zokusetshenziswa ezihlukene. Izinto ezisetshenziswayo ezihlukile zinezici ezihlukile, futhi ububanzi besicelo noma indawo yokusebenza ezifanelekile zihlukile. Ngakho-ke, isimiso sokukhetha izinto zokuhlunga zezitshalo zokuxuba i-asphalt kanye nabaqoqi bezikhwama zothuli yilezi: okokuqala, qonda ngokugcwele izakhiwo ezingokwenyama namakhemikhali zamagesi aqukethe uthuli akhishwa ngesikhathi senqubo yokukhiqiza, bese uhlaziya ngokucophelela ukusebenza kobuchwepheshe bemicu ehlukene ngaphambi kokwenza. ukukhetha. Lapho kukhethwa izinto zokuhlunga, izici okufanele zicatshangelwe zifaka: izici ezibonakalayo nezamakhemikhali zamagesi aqukethe uthuli, okuhlanganisa izinga lokushisa, umswakama, ukugqwala, ukuvutha kanye nokuqhuma.
Izakhiwo zamagesi aqukethe uthuli ngaphansi kwezimo ezahlukene zihlukile, futhi zizothinteka yizici eziningi. Igesi yamabhuzu emvula nayo iqukethe izinto ezonakalisayo. Uma kuqhathaniswa, i-polytetrafluoroethylene fiber, eyaziwa ngokuthi inkosi yamapulasitiki, inezindawo ezinhle kakhulu, kodwa iyabiza. Ngakho-ke, lapho ukhetha izinto zokuhlunga zezitshalo zokuxuba i-asphalt nabaqoqi bezikhwama zothuli, kuyadingeka ukubamba izici eziyinhloko ngokusekelwe ekwakhekeni kwamakhemikhali amagesi aqukethe uthuli bese ukhetha izinto ezifanele.
Ngaphezu kwalokho, izinto zokuhlunga zezitshalo zokuxuba i-asphalt kanye nabaqoqi bezikhwama zothuli kufanele zikhethwe ngokuhambisana nobukhulu bezinhlayiya zothuli. Lokhu kudinga ukugxila ekuhlaziyweni okungokomzimba kothuli, impahla, ukwakheka kanye nokucubungula kwangemuva kwezinto zokuhlunga, futhi ukukhethwa kufanele kuhlanganiswe nezici ezifana nokuma nokusabalalisa usayizi wezinhlayiyana zothuli.
