Ukugqunywa kwe-ACM sisihloko ebesixoxwe kakhulu kwiminyaka yakutshanje ngenxa yokunxulumana nomlilo odume kakubi we-Grenfell tower eLondon. Ukuba awuqhelananga ne-ACM yokugqoka, unokuzibuza ukuba yintoni kanye kwaye kutheni ibe ngumcimbi omkhulu. Kule nqaku, siza kuphonononga yonke into oyifunayo ukuba uyazi malunga ne-ACM yokugqoka kunye nendlela esetyenziswa ngayo kwizakhiwo.
Yintoni ukugquma kwe-ACM?
I-ACM imele imathiriyeli edibeneyo ye-aluminiyam. Njengoko igama libonisa, luhlobo lokugquma olwenziwa ngamacandelo amabini e-aluminium adityaniswe kumbindi wezinto ezahlukeneyo, ezidla ngokuba yi-polyethylene. Injongo ye-ACM yokugquma ngokuyinhloko kukuphucula imbonakalo yobuhle bendawo yangaphandle yesakhiwo, njengoko inika i-sleek, imbonakalo yanamhlanje.
Isetyenziswa phi i-ACM cladding?
I-ACM i-cladding inokufumaneka kuluhlu olubanzi lwezakhiwo, ezibandakanya zombini iindawo zokuhlala kunye nezorhwebo. Isetyenziswa ngokuqhelekileyo kwizakhiwo eziphakamileyo, kodwa ingasetyenziselwa kwizakhiwo ezincinci. Olu hlobo lokugquma luye lwasetyenziswa ukusukela ngoo-1960, kodwa ukuthandwa kwalo kunyukile kwiminyaka yakutshanje ngenxa yenkangeleko enomtsalane.
Kutheni i-ACM ibamba ingxabano?
Ingxabano ejikeleze i-ACM yokugquma yaqala ngo-2017 xa kwaqhambuka umlilo kwi-Grenfell Tower yaseLondon. Umlilo wasasazeka ngokukhawuleza, kwaye kamva kwafunyaniswa ukuba i-cladding esetyenziswe ngaphandle kwesakhiwo yayiyi-ACM. Izinto ezisetyenziselwa ukugquma kweGrenfell zifunyenwe zivutha kakhulu, nto leyo yavumela umlilo ukuba usasazeke ngokukhawuleza. Ngenxa yoko, abantu abaninzi baphulukana nobomi babo yaza le ntlekele yashiya ihlabathi lisentlungwini.
Intlekele yenqaba yaseGrenfell yayiyeyona ndawo iphambili yokusetyenziswa kwe-ACM yokugquma kwihlabathi liphela. Amazwe amaninzi akuyekile ukusetyenziswa kophahla lweACM kwizakhiwo eziphakamileyo. Ukukhathazeka okukhulayo koluntu malunga nokukhuselwa kwe-ACM yokugqoka kwiminyaka elandelayo emva kwentlekele kuye kwabangela ukuba izifundo ezininzi kunye nophando kwizinto eziphathekayo, ezikhokelela kwiingcali ezininzi ukuba zikholelwe ukuba i-ACM yokugqoka ibeka ingozi enkulu yomlilo.
Iingozi zokugquma kwe-ACM
Iingcali ziye zalumkisa ukuba i-ACM i-cladding ibeka ingozi enkulu yomlilo, ngokukodwa ngenxa yokuba i-polyethylene core esetyenziswe kwiindidi ezininzi ze-ACM zokugqoka zivutha kakhulu. Oku kuthetha ukuba xa kwenzeka umlilo, i-cladding inokubamba umlilo ngokulula kwaye isasaze amadangatye ngokukhawuleza, idala imeko eyintlekele.
Zeziphi ezinye iindlela zokugquma i-ACM?
Ukusukela kwintlekele yaseGrenfell Tower, abanini bezakhiwo abaninzi kunye nabayili bezakhiwo bebekhangela ezinye iindlela zokuvala i-ACM. Ngethamsanqa, kukho ezinye izinto ezininzi onokukhetha kuzo zombini ezithandekayo kwaye zikhuselekile.
Enye indlela ethandwayo yi-terracotta cladding. I-Terracotta yinto eyenziwe ngodongwe esetyenzisiweyo ekwakhiweni kwamawaka eminyaka. Yimathiriyeli eguquguqukayo kwaye eyomeleleyo enokuthi isetyenziswe ukwenza uyilo oluntsonkothileyo kunye neepateni, iyenza ibe lolona khetho lufanelekileyo kulwakhiwo lwangoku.
Enye indlela kukusebenzisa ibhodi yokugquma uboya beminerali ehonjiswe ngaphandle eneenkqubo zokunikezela. Le ndlela ingenye idala umphandle owomeleleyo kunye nobuhle obukholisayo ngelixa igcina ukhuseleko lomlilo olwaneleyo.
Ukuqukumbela
Ukugquma kwe-ACM luhlobo lokugquma olwenziwe ngamaleko amabini e-aluminiyam edityaniswe kumbindi wezinto ezahlukeneyo, kwaye iye yaba sisihloko esiphikisanayo kwiminyaka yakutshanje ngenxa yokunxulumana nomlilo wenqaba yaseGrenfell eLondon. Nangona yayikhe yalukhetho oludumileyo lokwakhiwa kwangaphandle ngenxa yenkangeleko yayo ethambileyo neyangoku, iipropathi zayo ezinokutsha zibeka umngcipheko omkhulu womlilo. Ngenxa yoko, abantu abaninzi abakwishishini lokwakha babhenela kwiindlela ezikhuselekileyo nezomelele ngakumbi ezisakhangeleka zintle.
