Izityalo zokuxuba i-asphalt ziya kuvelisa uthuli oluninzi kunye negesi yokukhupha eyingozi ngexesha lokwakha. Ukuze kuncitshiswe umonakalo obangelwa zezi zingcolisi, izixhobo ezifanelekileyo zokususa uthuli zilungiselelwa unyango. Okwangoku, iintlobo ezimbini zezixhobo zokususa uthuli, ezibandakanya abaqokeleli bothuli lwe-cyclone kunye nabaqokeleli bothuli lwengxowa, ngokuqhelekileyo zisetyenziselwa ukuqokelela ukungcola kangangoko kunokwenzeka ukunciphisa ukungcola kunye nokuhlangabezana nemigangatho yemimiselo yokukhusela indalo.
Nangona kunjalo, kule nkqubo, izixhobo ezikhethiweyo zokususa uthuli kufuneka zihlangabezane neemfuno ezithile. Ngokukodwa ekukhethweni kwezinto zokucoca, kuba emva kwexesha lokusetyenziswa kwezixhobo zezityalo zokuxuba i-asphalt kunye nabaqokeleli bothuli lomatshini, izinto zokucoca ziya konakaliswa ngenxa yezizathu ezithile kwaye kufuneka zilungiswe okanye zitshintshwe. Ngoko ke, ukuba yeyiphi into yokucoca into yokukhetha ngumbuzo ofanele ukucinga ngawo. Indlela eqhelekileyo kukukhetha ngokungqinelana nezibonelelo kunye neemfuno zencwadana yemiyalelo yesixhobo okanye imanyuwali yokulungisa, kodwa ayikalunga.

Ngesiqhelo, zininzi iintlobo zemathiriyeli ekrwada ezisetyenziselwa ukucoca imathiriyeli ukuhlangabezana neemfuno ezahlukeneyo zokusetyenziswa. Izinto eziluhlaza ezahlukeneyo zineempawu ezahlukeneyo, kwaye uluhlu lwesicelo okanye indawo yokusebenza efanelekileyo kuyo yahlukile. Ngoko ke, umgaqo wokukhetha izixhobo zokucoca izityalo zokuxuba i-asphalt kunye nabaqokeleli bothuli lwengxowa kukuba: okokuqala, ukuqonda ngokupheleleyo iimpawu zomzimba kunye neekhemikhali zegesi ezinothuli ezikhutshwe ngexesha lenkqubo yokuvelisa, kwaye emva koko uhlalutye ngononophelo ukusebenza kobugcisa bemicu eyahlukeneyo ngaphambi kokwenza. ukhetho. Xa ukhetha izinto zokucoca, izinto eziza kuqwalaselwa zibandakanya: iimpawu ezibonakalayo kunye neekhemikhali zegesi ezinothuli, kubandakanywa ubushushu, ukufuma, ukubola, ukutsha kunye nokuqhuma.
Iimpawu zeegesi ezinothuli phantsi kweemeko ezahlukeneyo ziyahluka, kwaye ziya kuchaphazeleka kwizinto ezininzi. Irhasi yeebhutsi zemvula nayo iqulethe izinto ezonakalisayo. Ngokuthelekisa, i-polytetrafluoroethylene fiber, eyaziwa ngokuba yinkosi yeeplastiki, inezakhiwo ezintle kakhulu, kodwa iyabiza. Ngoko ke, xa ukhetha izinto zokucoca izityalo zokuxuba i-asphalt kunye nabaqokeleli bothuli lwengxowa, kuyimfuneko ukuba ubambe izinto eziphambili ngokusekelwe kwimichiza yeegesi ezinothuli kwaye ukhethe izinto ezifanelekileyo.
Ukongezelela, izinto zokucoca izityalo zokuxuba i-asphalt kunye nabaqokeleli bengxowa yothuli kufuneka zikhethwe ngokobukhulu beengqungquthela zothuli. Oku kufuna kugxininise kuhlalutyo lomzimba lothuli, izinto eziphathekayo, ulwakhiwo kunye ne-post-processing yezixhobo zokucoca, kwaye ukhetho kufuneka ludibaniswe nezinto ezifana nokuma kunye nokusabalalisa ubungakanani be-particle yothuli.
