Uhlalutyo lweNtsebenzo yokuTsha kwaMashidi eLining: iMigangatho yoKhuseleko kunye neeMpawu zeMarike
Jul 23, 2025
Ngokuphuculwa okuqhubekayo kweemfuno zokhuseleko lwezinto eziphathekayo kwiindawo zokwakha, ezothutho kunye nezoshishino, ukusebenza kokutsha kwamaphepha e-lining kuye kwaba sesinye sezibonakaliso eziphambili zabathengi behlabathi. Olu hlobo lwezinto eziphathekayo lusetyenziswa ngokubanzi kwiimeko ezifana neenqwelo, iikhabhini zeenqanawa, kunye nezahlulo zokwakha. Iipropati zayo ezivuthayo zomlilo zihambelana ngokuthe ngqo nokhuseleko lwabasebenzi kunye nokukhuselwa kwepropati. Eli nqaku liza kuhlalutya iimfuno zokusebenza zokutsha zamaphepha e-lining ukusuka kwimiba emithathu: imigangatho yobugcisa, iindlela zokuvavanya, kunye neendlela zemarike.
Iimpawu eziphambili zokusebenza kokutsha
Ukusebenza kokutsha kwamaphepha e-lining ngokuqhelekileyo kuhlolwe iiparameters ezifana ne-oxygen index (OI), i-smoke density rating (SDR), kunye nesantya sokusasazeka komlilo. Ukuphakama kwesalathisi se-oksijeni, kunzima ngakumbi ukutshisa izinto eziphathekayo; Iqondo lokuxinana komsi libonisa umyinge womsi oveliswayo ngexesha lokutsha, nto leyo ibalulekileyo ekuphumeni ngexesha likaxakeka. Imigangatho yamazwe ngamazwe efana ne-EN 45545 (umgangatho wokukhusela umlilo kaloliwe waseYurophu), i-ASTM E84 (uvavanyo lokutshisa umphezulu wase-US), kunye ne-GB 8624 (i-China izixhobo zokwakha ulwahlulo lokukhusela umlilo) zonke zineemfuno zokuhlela ezicacileyo zamaphepha kwiimeko ezahlukeneyo zesicelo. Umzekelo, indawo yokuhamba kaloliwe idla ngokufuna imathiriyeli ukufikelela kwinqanaba le-EN 45545 HL3, elona nqanaba liphezulu lokubuyiswa komlilo.
Iindlela zokuvavanya kunye nenkqubo yokuqinisekisa
Iimvavanyo zentsebenzo yokutsha yeepaneli ze-lining kwimarike yamazwe ngamazwe zidla ngokuhlulwa zibe ziindidi ezimbini: ukulinganisa kwelabhoratri kunye nokuqinisekiswa kweyona ndawo. Uvavanyo lwaselabhoratri lubandakanya iimvavanyo zokutsha ezithe nkqo, iimvavanyo zokutsha ezithe tyaba, kunye nohlalutyo lomsi kunye negesi eyityhefu. Ukuthatha i-ASTM E84 njengomzekelo, olu vavanyo lwahlula izixhobo kwiKlasi A (i-best flame retardancy), i-Class B, kunye ne-Class C ngokulinganisa isantya esivuthayo kunye nokukhutshwa komsi wezinto phantsi kwesenzo somlilo. Iimveliso eziqinisekisiweyo kufuneka zikhatshwe -ziingxelo zovavanyo lomntu wesithathu, ezifana nesatifikethi se-UL okanye iingxelo ze-Intertek, ukuhlangabezana neemfuno zokuthotyelwa kwemarike yokuthumela ngaphandle.
Iindlela zentengiso kunye nokutsha kwezobuchwepheshe
Kwiminyaka yakutshanje, izinto ezihambelana nokusingqongileyo ze-flame retardant ziye zaba yingqwalasela yoshishino. Nangona ii-halogen flame retardants zisebenza kakuhle, zinokukhupha iigesi eziyityhefu xa zitshisiwe, ngoko ke i-halogen -ekhululekile, ephantsi{2}}i-phosphorus yomsi okanye i-nitrogen ebuyisela amadangatye ngokuthe ngcembe ilawuleka. Ukongeza, imathiriyeli edityanisiweyo efana neepaneli zesangweji ye-aluminiyam ye-honeycomb zinesidingo esikhulu kwinqwelomoya kunye{4}}nendawo yolwakhiwo ephezulu ngenxa yobunzima bazo kunye nokucotha okukhulu kwedangatye. Ngokweengxelo zemizi-mveliso, imarike yephaneli yelangatye yelangatye ye-retardant kulindeleke ukuba yande ngesantya esihlanganisiweyo sonyaka sokukhula nge-6% kule minyaka mihlanu izayo, kwaye ummandla wase-Asiya{8}}ummandla we-Pasifiki uya kuba ngowona mmandla wokukhula ngenxa yokonyuka kotyalo-mali lweziseko ezingundoqo.
Ukukhetha iipaneli ze-lining ezihlangabezana nemigangatho yamazwe ngamazwe akukona nje ukuhlangabezana neemfuno ezisisiseko zemimiselo, kodwa kunye nesitshixo sokuphucula ukukhuphisana kwemveliso. Abathengi kufuneka badibanise iinkcukacha ezithile zeemarike ekujoliswe kuzo kwaye banike kuqala kubanikezeli abanesatifikethi esigunyazisiweyo ukuqinisekisa ukuba izinto eziphathekayo zifezekisa ibhalansi engcono kakhulu yokukhusela umlilo, ukukhuselwa kwendalo kunye nokuqina.
