Uma uthenga izinkundla zemabula noma ama-slabs, ungase uzwe ngokuvamile amagama athi A-grade, B-grade, kanye ne-C-grade materials. Abantu abaningi ngephutha bahlobanisa lezi zigaba namazinga emisebe. Eqinisweni, lokho kuwukungaqondi. Izinto zesimanje zemabula zezakhiwo nezezimboni ezisetshenziswa emakethe namuhla ziphephe ngokuphelele futhi azinayo imisebe. Isistimu yokugreda esetshenziswa embonini yamatshe negwadle isho ukuhlukaniswa kwekhwalithi, hhayi ukukhathazeka kokuphepha.
Ake sithathe imabula yeSesame Grey (G654), itshe elisetshenziswa kakhulu ekuhlobiseni kwezakhiwo nezisekelo zemishini, njengesibonelo. Embonini yamatshe, le nto ivame ukuhlukaniswa ngamamaki amathathu ayinhloko—A, B, no-C—ngokusekelwe ekushintshashintsheni kombala, ukuthungwa kwendawo, nokungapheleli okubonakalayo. Umehluko phakathi kwala mabanga usekubukekeni, kuyilapho izici ezingokomzimba ezifana nokuminyana, ubulukhuni, namandla okucindezela kusalokhu okufanayo.
Imabula ye-A-grade imele izinga eliphezulu kakhulu. Ifaka ithoni yombala ofanayo, ukuthungwa okubushelelezi, nendawo engenasici ngaphandle kokuhluka kombala obonakalayo, amabala amnyama, noma imithambo. Isiphetho sibonakala sihlanzekile futhi sihle, okuyenza ifaneleke ekuhlanganisweni kwezakhiwo ezisezingeni eliphezulu, izinkundla zemabula ezinembayo, kanye nezindawo zokuhlobisa zasendlini lapho ukuphelela okubonakalayo kubalulekile.
Imabula ye-B-grade igcina ukusebenza okufanayo komshini kodwa ingase ibonise ukuhluka okuncane, okwenzeka ngokwemvelo kumbala noma ukuthungwa. Ngokuvamile awekho amachashazi amakhulu amnyama noma amaphethini emithanjeni aqinile. Lolu hlobo lwamatshe lusetshenziswa kakhulu kumaphrojekthi adinga ibhalansi phakathi kwezindleko nekhwalithi yobuhle, njengokubeka phansi kwezakhiwo zomphakathi, amalabhorethri, noma izinsiza zezimboni.
Imabula ye-C-grade, ngenkathi isazwakala kahle ngesakhiwo, ibonisa umehluko obonakalayo wemibala, amabala amnyama, noma imithambo yetshe. Lokhu kungapheleli kobuhle kuyenza ingalungeli kakhulu izinto zangaphakathi ezinhle kodwa yamukeleke ngokuphelele ekufakweni kwangaphandle, izindlela zokuhamba, namaphrojekthi amakhulu wobunjiniyela. Noma kunjalo, imabula ye-C-grade kusafanele ihlangabezane nezidingo ezibalulekile zobuqotho—ayikho imifantu noma ukuphuka—futhi igcine ukuqina okufanayo namabanga aphezulu.
Ngamafuphi, ukuhlukaniswa kwezinto ezinjengo-A, B, kanye no-C kubonisa ikhwalithi ebonakalayo, hhayi ukuphepha noma ukusebenza. Kungakhathaliseki ukuthi isetshenziselwa amapuleti angaphezulu kwemabula, izinkundla zegwadle ezinembayo, noma izakhiwo zokuhlobisa, wonke amabanga akhethwa ngokuqinile futhi acutshungulwe ukuze kuqinisekiswe ukuzwakala kwesakhiwo nokuzinza kwesikhathi eside.
Kwa-ZHHIMG®, sibeka phambili ukukhetha kwezinto njengesisekelo sokunemba. Igwalagwala lethu elimnyama le-ZHHIMG® liklanyelwe ukwedlula imabula evamile ngokuminyana, ukuzinza, nokumelana nokudlidliza, iqinisekisa ukuthi yonke inkundla enembayo esiyikhiqizayo ihlangabezana nezindinganiso zomhlaba wonke eziphakeme kakhulu. Ukuqonda ukugredwa kwezinto kusiza amakhasimende enze izinqumo ezinolwazi—ukukhetha ibhalansi efanele phakathi kwezidingo zobuhle nokusebenza komsebenzi.
