Iphaneli yeAluminiyam ehlanganisiweyo yabavelisi kunye nababoneleli eChina ukusukela ngo-2002 - iHenglicai ACP
Ukusetyenziswa kweepaneli ze-ACM kuye kwaba yinto efunekayo kwizakhiwo zanamhlanje, kwaye kungekho sizathu. I-ACM, imfutshane kwi-Aluminium Composite Material, yinto yokugquma eyenziwe ngezikhumba ezimbini ze-aluminiyam ezidityaniswe macala omabini ento engundoqo. Imveliso ephumayo ibonelela ngeenzuzo ezininzi kubakhi bezakhiwo kunye neenjineli, ezinje ngokuphakama okuphezulu, ukuqina, kunye noluhlu olubanzi lokugqitywa okwenza ukuba lulungele izicelo ezahlukeneyo.
Enye yeengenelo ezibaluleke kakhulu zeepaneli ze-ACM yimpahla yazo yokumelana nomlilo, ezinegalelo elikhulu ekwakheni ukhuseleko kunye nokuthotyelwa kwekhowudi. Kule nqaku, siza kujonga ngokubanzi kwisayensi emva kokumelana nomlilo kweepaneli ze-ACM.
Isihlokwana 1: Ukuqulunqwa kweePaneli zeACM
Ngaphambi kokungena kwisayensi yokumelana nomlilo, kubalulekile ukuqonda ukubunjwa kweepaneli ze-ACM. Njengoko kukhankanyiwe ngaphambili, iphaneli yenziwe ngezikhumba ezimbini ze-aluminiyam, eziqhelekileyo ziyi-0.2 ukuya kwi-0.5 mm ubukhulu, ziboshwe kuwo omabini amacala ezinto ezingundoqo. Izinto ezingundoqo ngokuqhelekileyo zenziwe ngenye yezinto ezintathu: i-polyethylene, i-fire-retardant (FR) core, okanye i-core non-combustible mineral-filled fill.
Uhlobo lwezinto eziphambili ezisetyenziswe kwiipaneli ze-ACM zidlala indima ebalulekileyo ekuchaseni umlilo, njengoko siza kuhlola kwicandelo elilandelayo.
Isihlokwana sesi-2: Undoqo weFR
Njengoko igama libonisa, i-FR core yenzelwe ngokukodwa ukuxhathisa imililo. Yenziwe ngesixhobo se-thermoplastic ethi, xa ibonakaliswe kubushushu, isabela ngokwekhemikhali ukuthintela ukusasazeka kwamadangatye. Undoqo uqulethe i-retardant yomlilo, ngokuqhelekileyo i-alumina trihydrate (ATH), ukwandisa iimpawu zayo zokunqanda umlilo.
Xa iphantsi komlilo, i-FR core yeepaneli ze-ACM ivelisa iigesi ezingenakutsha ezinceda ukulamba umlilo we-oksijini, ukuthintela ukusasazeka kwayo. Ngaphezu koko, umaleko womphezulu wepaneli unikezela ngenqanaba elithile lokumelana nomlilo ngokudala umqobo phakathi komlilo kunye nezinto eziphambili.
Isihlokwana sesi-3: Undoqo ozaliswe zizimbiwa
Ngokungafaniyo ne-FR core, i-mineral-filled core ayinakutsha ngokupheleleyo. Yenziwe ngumxube weekhompawundi ze-inorganic ezifana ne-magnesium oxides, i-aluminium hydroxides, kunye ne-mineral fillers. Xa ujongwe emlilweni, undoqo ukhupha umphunga wamanzi, onceda ukupholisa umlilo kwaye uthintele ukusasazeka kwawo.
Undoqo ozaliswe ziiminerali ngowona unokuxhathisa umlilo kwiintlobo ezintathu eziphambili, kodwa ukwangowona unzima kwaye ubiza kakhulu. Ngokuqhelekileyo isetyenziswa kwizakhiwo eziphakamileyo, apho ukumelana nomlilo kubaluleke kakhulu.
Isihlokwana sesi-4: I-Polyethylene Core
I-polyethylene core iyona nto isetyenziswa kakhulu kwi-ACM panels. Yenziwe ngesixhobo se-thermoplastic esinokutsha kakhulu, nto leyo eyenza kube yinto engalunganga kwizicelo ezichasene nomlilo.
Iipaneli ze-ACM ezine-Polyethylene-cored zihlelwa njengezixhobo zeKlasi B ngokwemiqathango yokumelana nomlilo, oku kuthetha ukuba zifanelekile ukusetyenziswa kwizakhiwo ukuya kwimigangatho emine ephezulu. Iiphaneli zikwahlala zigqunywe ngezinto ezikwaziyo ukumelana nomlilo ukuze ziphucule iimpawu zazo zokumelana nomlilo.
Isihlokwana sesi-5: Ukuthotyelwa kweKhowudi kunye neSiqinisekiso
Iikhowudi zokwakha zibekiwe ukuqinisekisa ukhuseleko lwabantu abahlala kwizakhiwo. Ngaloo ndlela, kubalulekile ukuqinisekisa ukuba iipaneli ze-ACM ezisetyenziswe kwisakhiwo zihlangabezana nemigangatho efanelekileyo yokumelana nomlilo.
E-US, i-National Fire Protection Association (NFPA) ibeke izikhokelo zokuchasa umlilo kwizinto zokwakha. I-NFPA 285 yindlela yovavanyo eqhelekileyo yokuvavanya iimpawu zokusasaza umlilo zangaphandle, iindibano zodonga ezingathwali mthwalo eziqulethe izinto ezinokutsha.
Abenzi bephaneli ze-ACM kufuneka bangenise iimveliso zabo kwiibhubhoratri ezivunyiweyo zokuvavanya kunye nokuqinisekiswa kokuqinisekisa ukuthotyelwa kwe-NFPA 285 kunye nezinye iikhowudi kunye nemigangatho efanelekileyo.
Ukuqukumbela
Ukusebenzisa iiphaneli ze-ACM kulwakhiwo lwangoku kunika abakhi bezakhiwo kunye nabaqulunqi uluhlu lweenzuzo, kubandakanya ukuthambeka okuphezulu, ukuqina, kunye noluhlu olubanzi lokugqitywa. Nangona kunjalo, enye yezona zinto zibalulekileyo kwiiphaneli ze-ACM ziipropati zabo zokumelana nomlilo.
Uhlobo lwezinto eziphambili ezisetyenziswa kwiiphaneli ze-ACM zidlala indima ebalulekileyo ekuxhathiseni umlilo. I-FR kunye ne-mineral-filled cores inikeza inqanaba eliphezulu lokumelana nomlilo, ngelixa iinqununu ze-polyethylene zinika iidigri ezingaphantsi kokumelana nomlilo.
Ukuthotyelwa kwemigaqo yesakhiwo kunye nemigangatho kubalulekile ukuqinisekisa ukhuseleko lwabantu abahlala kwizakhiwo. Abavelisi bephaneli ye-ACM kufuneka bangenise iimveliso zabo kwiibhubhoratri ezivunyiweyo zokuvavanya kunye nokuqinisekiswa kokuqinisekisa ukuthotyelwa kweekhowudi ezifanelekileyo kunye nemigangatho.
