Inqaku le-1: Ukuqonda iNgcaciso yoKhuseleko loMlilo lweePaneli ze-ACM
Iiphaneli ze-ACM, ezimfutshane kwiiPaneli ze-Aluminium Composite Panels, ziye zafumana ukuthandwa okuphawulekayo kulwakhiwo kunye neeprojekthi zezakhiwo ngenxa yokubonakala kwazo, ukuqina, kunye nokulula ukufakwa. Nangona kunjalo, xa kuziwa kukhuseleko lomlilo, kubalulekile ukuqonda ukulinganiswa komlilo kweepaneli ze-ACM. Kule nqaku, siya kukhangela kwiinkcukacha zomlilo ze-ACM, ukubaluleka kwazo, kunye nefuthe labo ekwakheni ukhuseleko.
Imithetho yokhuseleko lomlilo iye yaqina ngakumbi, yaye abayili bezakhiwo, abakhi, nabanini bezakhiwo baye babeka phambili ukusetyenziswa kwezinto ezikwaziyo ukumelana nomlilo. Iiphaneli zeACM azikho ngaphandle. Makhe sihlolisise ukuba yeyiphi ireyithingi yomlilo eyabelwe iiphaneli ze-ACM kunye nokuba kukuchaphazela njani ukufaneleka kwazo kwizicelo ezahlukeneyo.
Inqaku leSihlokwana sesi-2: Ukuqonda ukulinganiswa koMlilo kunye nokubaluleka kwabo
Ngaphambi kokuba uphonononge kumazinga omlilo eephaneli zeACM, kubalulekile ukuqonda iziseko zokulinganisa umlilo ngokwazo. Imilinganiselo yomlilo ilinganisa ukukwazi kwezinto eziphathekayo ukuxhathisa umlilo kunye nokukhusela isakhiwo esisezantsi. Ezi zilinganiso zabelwe ngokusekelwe kwimigangatho yovavanyo ethile esekwe ngamaqumrhu alawulayo, afana ne-American Society for Testing and Materials (ASTM) kunye ne-Underwriters Laboratories (UL).
Iireyithingi zomlilo zidla ngokuqwalasela izinto ezahlukeneyo, kubandakanya ukusasazeka kwedangatye, ukuveliswa komsi, kunye nezinga lokukhutshwa kobushushu. Amanqaku aphezulu omlilo abonisa iipropati ezingcono zokukwazi ukumelana nomlilo, okwenza imathiriyeli enomlinganiselo onjalo ikhetheke kwizicelo apho ukhuseleko lomlilo luyinkxalabo.
Inqaku leSihlokwana sesi-3: Imilinganiselo yoMlilo ye-ACM kunye neMigangatho yoHlelo
Iiphaneli ze-ACM zifumaneka kuluhlu lwemilinganiselo yomlilo, nganye yenzelwe ukuhlangabezana neemfuno ezahlukeneyo. Ukuhlelwa komgangatho womlilo osetyenziswa ngokuqhelekileyo kwiiphaneli ze-ACM e-United States ilawulwa yi-ASTM E84, eyaziwa ngokuba yi "Indlela yoVavanyo oluMiselweyo kwiiMpawu zokuBusa uMphezulu weZixhobo zoKwakha." Lo mgangatho ulinganisa ukusasazeka kwedangatye kunye nokwakhiwa komsi wezinto ezahlukeneyo.
Iiphaneli ze-ACM ngokuqhelekileyo ziwela kwiindidi ezimbini eziphambili: Iklasi A kunye neKlasi B. Iiphaneli ze-ACM zeKlasi ye-ACM zinezinga eliphezulu lomlilo kwaye zinokumelana nomlilo. Banesalathisi sokusasazeka komlilo we-0-25 kunye nesalathisi esiphuhliswe ngumsi se-0-450. Iiphaneli ze-ACM zeKlasi B zinezinga eliphantsi lomlilo eliphantsi, kunye nesalathisi sokusasazeka komlilo we-26-75 kunye nesalathisi esiphuhliswe ngumsi se-0-450.
Isihlokwana seSiqendu sesi-4: Izinto ezichaphazela iPhaneli ye-ACM yokuPhathwa koMlilo
Izinto ezininzi zinegalelo kumlinganiselo womlilo weepaneli ze-ACM, kubandakanywa izinto zabo eziphambili, iingubo, ubukhulu bepaneli, kunye nokwakhiwa ngokubanzi. Izinto ezingundoqo zinokuchaphazela kakhulu ukuxhathisa umlilo. Iiphaneli ze-ACM ngokuqhelekileyo zinesiseko esenziwe nokuba yi-polyethylene (PE), i-fire-retardant (FR) core, okanye i-mineral-filled (MF) core.
Iipaneli ze-PE core ACM zinezinga eliphantsi lomlilo phakathi kweendlela ezintathu, okwenza ukuba zilungele izicelo ezithile apho ukhuseleko lomlilo lungabalulekanga kangako. Iiphaneli ze-ACM eziphambili ze-FR zinika ukuphuculwa kokumelana nomlilo, ngelixa iipaneli ze-ACM eziphambili ze-MF zibonelela ngenqanaba eliphezulu lokumelana nomlilo.
Ukongezelela, i-coating esetyenziswe kwiipaneli ze-ACM inokuchaphazela ukulinganiswa komlilo. Iingubo ezikhethekileyo ezinomlilo zinokuphucula ngakumbi iipropati ezichasene nomlilo zeepaneli ze-ACM. Ubungqingqwa bephaneli bukwadlala indima, njengoko iiphaneli ezityebileyo zibonelela ngokubanzi ukuxhathisa umlilo kunezo zibhityileyo.
Inqaku leSihlokwana sesi-5: Ukuqwalaselwa kwezicelo zePhaneli ye-ACM
Xa ukhetha iiphaneli zeACM zeprojekthi, kubalulekile ukuqwalasela iimfuno zokukala komlilo ezichazwe ziikhowudi zokwakha kunye nemimiselo yendawo. Izicelo ezithile, ezifana nezakhiwo eziphakamileyo okanye izakhiwo ezinomngcipheko okhulayo womlilo, zingadinga ukusetyenziswa kweepaneli ze-ACM zeKlasi A. Ngakolunye uhlangothi, iipaneli ze-ACM zeKlasi B zinokufaneleka kwizicelo ezinokukhathazeka okuncinci kokhuseleko lomlilo.
Ukubonisana kunye neengcali zokhuseleko lomlilo kunye nokubambelela kwiikhowudi zokwakha zendawo kuqinisekisa ukuba ukulinganiswa komlilo okhethiweyo weepaneli ze-ACM zihambelana neenjongo zokhuseleko jikelele zeprojekthi. Ukongezelela, ukugcinwa rhoqo kunye nokuhlolwa kwexesha leepaneli ze-ACM, ezifana nokujonga nayiphi na imiqondiso yomonakalo okanye ukugqoka, igalelo ekugcineni iipropati zabo ezinokumelana nomlilo ngexesha.
Isiphelo:
Ukuqonda ukulinganiswa komlilo kwiipaneli ze-ACM kubalulekile ukuqinisekisa ukhuseleko kunye nokuthotyelwa kweeprojekthi zokwakha. Ngokukhetha iiphaneli ezifanelekileyo ze-ACM ezinomlilo, ukuqwalasela izinto ezifana neyona nto ingundoqo, i-coating, kunye nobukhulu, abakhi bezakhiwo kunye nabakhi banokuphucula ukuxhathisa umlilo wesakhiwo. Ukuthobela imimiselo yendawo kunye nokubonisana nabaqeqeshi bokhuseleko lomlilo ngamanyathelo ayimfuneko xa ufaka iipaneli ze-ACM kuyo nayiphi na iprojekthi yokwakha.
