Indlela okuyimbiyo yokuhlaba kweziblade ezingapheli ngaphakathi kwemikhosi eyinhloko yamazinyo

Umgomo wokuhlaba kweziblade ezingapheli ngokusebenzisa imithombo yamazinyo

Amaphutha we-chloride angaphuma kwezinye izindawo zokuphuma kwemithambo yasekupheleni kuyenza izinkinga zezinhlobo zezimfundo zokuchitha ngokushesha kublade yediamond engeyona yobukhulu. Okufana nokuthi lezi amaphutha ayaphuma kumkhono wamaphutha okuhamba kusuka kwezinye izikhala ezincinci, futhi abhekisele izinkampani zokuchitha ngokushesha kusuka kwezinye izikhala. Uma isalt ibuyela kusuka kwezinye izikhala, iyakha izindlela ukuze umoya wokugcina uphume, okuyakhula izinkinga ezimbili. Okokuqala, ukuchitha ngokushesha kwenza ukuthi ubukhulu buphuma kuwo wonke umphakathi wokuchitha kweblade. Okwesibili, kukho lokhu ocaciswa ngokuthi ngokuchitha kwe-galvanic, okufana nokuthi amaphutha amabili akhuluma nangaphakathi kwebhlade. Ngokuzinhlaka, lezi zinkinga ziyakhiwa ngokushesha ukuchitha kwezinto eziphambili zokubeka amaphutha ayo amadiamond, okuvuleka ukuthi iziqephu ziyachithwa ngokushesha, futhi emva kwalokho iblade yonke iyachithwa ngokushesha. Izinkinga ziyagcwele kakhulu uma kubonwa ukuthi kunezindlela zokuhlala kwezintathu zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zokuphuma kwezinye izikhala zok......

Izindaba zemisipakhi: Ukuphela kweblaydi kungabili ngokushesha kakhulu (62%) emithambo engenakwenzeka ukuthi ibe yinkululeko yokukhanya emaphakathi kwezindawo ezingaphezu kwe-5 km kwekhalasi (Inguqulelo ye-2023 ye-CIB)

Ngokwesibonelo seConstruction Industry Board esika-2023, iziblayidi ezingasuswanga zihlwa ngokushesha kakhulu ngokulingana ne-62% lapho zisebenzisa emaphakathi kwezindawo ezingaphezu kwe-5 km kwekhalasi kungafani nempahla ephakathi. Ukugula kubonakala ngokushesha futhi, ngokuthi izibhodwe zingabonakala ngokushesha kakhulu kuphela ema-veki amaningi, futhi izibhodwe ezikhulu ziyagqoka ngaphakathi kwemibhodwe ema-300 ama-hora okusebenza. Okumangalisayo kakhulu kukuthi ngokuvamile, iziblayidi eziyishumi nezinye zeziblayidi eziyishumi ziyagula ngokuthi izinyanga zizihlwa ngokukhanya kungafani nokuhlanza kwe-diamond okunormal. Lokhu kubiza izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungafanele ezikhipha izindlela zokufaka izinto eziphakeme ngokungaf......

Ukuthi iziblayidi ezingakwenzeka ukuthi zibe yinkululeko yokukhanya ziyakhathazeka njani ukugula emizini yamaphakathi

Ukubambisana kwezinhlangano zemvelo nezinhlangano zemithali yezinkolo: Ukuvikela ukufika kwe-ions zesi-chloride

Amaphakathi akhiwe ukuze ahlale amandla ekuphulukweni kwemithi, futhi abhekene ngokuphelele nempilo engcono yezindawo eziphakathi kwezinye zemikhosi ngokusebenzisa ubuchwepheshe obuhle bokusebenzisa izinhlangano. Izinhlangano zokubambisana ezihlelwe kuzo izinhlangano zemvelo zibamba ngokujabula amaphakathi okudlula amaphakathi amadlamini, futhi izinkolo zemithali yezinkolo zihlala zimandla nakwheni esebenzisa umoya ophakathi kwezinkolo.
