Flame retardants ngoba metal izakhiwo kanye abakhiqizi zabo

Wonke umuntu uyazi ukuthi metal akanawo izindawo ezivuthayo kodwa ngamazinga ashisa kakhulu okokusebenza kuba nezimo xaxa, mbaxa amafomu ahlukahlukene kokulahlekelwa umthwalo ethwele amandla. isakhiwo esinjalo ngesikhathi umlilo kungaholela ngokuwa ibhilidi noma iyiphi ingxenye yayo ukuthi kuyingozi ukuba ukuphila komuntu. Ukuze ugweme lokhu, sebenzisa ezihlukahlukene ilangabi retardants.

Uyini ukuvikelwa umlilo izakhiwo steel?

Fire ukuphepha - iqoqo izixazululo lobuchwepheshe, kuhlanganise ukucutshungulwa nensimbi izakhiwo, lapho ilangabi cishe yizona ezisetshenziswa kabanzi ukwakheka usebenzisa. inqubo okunjalo kwezinkolo kubizwa ngokuthi yokwenziwa abantu bavikelekile ezingozini zomlilo. Buildings ukuthi kungukuthi kusetshenzwe by isakhiwo idatha, abe ezingeni eliphansi umlilo ukumelana, okusho ukuthi isakhiwo uzoqala liphuke ngisho phambi izisulu ngeke asuswe ezindaweni zawo.

Ukwandisa le Inkomba kwenzeka ngenxa ukwakheka phezu ifilimu ekhethekile, okuyinto kubambezela inqubo amandla omlilo, ukuvikela isakhiwo ekubhujisweni okusheshayo.

Yezindlela eziphumelela kakhulu ukuvikela metal izakhiwo emiphumeleni umlilo

Ngosizo lwezobuchwepheshe banamuhla kanye ukuthuthukiswa ngokushesha yasungulwa ngezindlela eziningi ukuze banciphise umthelela lentuthu metal Alloys ahlukahlukene. Flame retardants kuya izakhiwo ebusweni akha ukushisa ekuvikeleni ungqimba okuyinto umlilo yokwenziwa, umelana okushisa aphakeme bese imiphumela ngqo lomlilo.

Fire cishe yizona ezisetshenziswa kabanzi ukwakheka ngoba metal kuyasiza ukwandisa ukuzinza ezishisayo we isakhiwo ngenxa yokufudumala kwembulunga kancane metal. Ngakho, isakhiwo singalondoloza izici zayo kwesakhiwo isikhathi esithile. It uhlala kuphela ukukhetha indlela efanele Ukuvikelwa yokwenziwa zezakhiwo.

izindlela eziphumelelayo khona okuvikela umlilo:

• Intumescent ilangabi retardants ukwandisa ukumelana umlilo ukwakhiwa imizuzu engu-90;
• usimende ungakwazi ukwandisa ukumelana umlilo embundwini 180 amaminithi, futhi nakakhulu;
• ebhekene amapuleti, ziphathwe kwakwakhe ekhethekile bakwazi ukwandisa ukumelana umlilo ukuba imizuzu 180 noma ngaphezulu.

Indlela ukukhetha indlela yokwakheka cishe yizona ezisetshenziswa kabanzi flame?

Ukuze yenze Ukuvikelwa, kukhethwa ingxube okudingekayo ukuze ukuqhuba ukuhlaziya lobuchwepheshe nezomnotho into bese ibheka izici ezilandelayo:

• Ukukala isakhiwo umlilo ukumelana ngaphandle ukuvikelwa eyengeziwe.
• Izinga design and ukumisa.
• Ukuba khona noma ukungabi khona imikhawulo isisindo enamathela ilangabi cishe yizona ezisetshenziswa kabanzi.
• Izici okusebenzela kuyo isakhiwo kanye nokwenzeka nemisebenzi yokwakhiwa futhi ukwakhiwa.
• Ukuhlolwa kwedivayisi kwemvelo futhi impahla kwemvelo zokuzivikela.
• Isikhathi esabelwe isicelo se cishe yizona ezisetshenziswa kabanzi flame.
• izidingo Tebuciko ngoba ukubonakala emagcekeni noma ukwakhiwa nokunye.

Ingabe kubalulekile ukuvikelwa umlilo?

Nge ilungelo indlela retardants ngeke kuphela ukuvikela isakhiwo emlilweni, kodwa futhi nokusindisa izimpilo.

Chemistry sifundo satshelwa ukuthi amazinga okushisa aphakeme ukwenza metal ezithambile. Phakathi umlilo, izinga lokushisa udlula 500 ° C, okusho ukuthi umklamo olungavikelekile aqala ukulahlekelwa impahla yabo umthwalo eziveza e ngeminithi lokuqala. Ukwandisa nalesi sikhathi, izindlela ezehlukene ngenxa yokwanda kwensimbi embundwini ukumelana. Kulokhu kuyoba okwanele ukuba kuphunywe abantu ukucima.

Isimiso ezisebenza we zokuzivikela Ukwakheka intumescent

izingoma Intumescent - lokhu ingenye izinkomba ethembisayo ekuvimbeleni umlilo, metal izakhiwo. Isimiso wokusebenza liqukethe ukuthi ezishisayo ekuvikeleni ungqimba ayikuvumeli ukuba nomusa kwensimbi futhi ulahlekelwe umthwalo esindayo umthamo ngamazinga ashisa kakhulu. Lapho wadalula ezishisayo ekuvikeleni ungqimba luyanda cishe ezingu-40 eshumini, ngenxa yalokhu ezishisayo ukwahlukanisa izakhiwo zalo ikhuphuke kakhulu.

Imiyalo yesimanje intumescent Izingxube bathi badinga ozofakwa evikelwe ebusweni ungqimba mayelana 2 mm obukhulu. Uma lisetshenziswa kubantu abaningi emikhulu, khona-ke izimo eziphuthumayo ungqimba nombala sekuqala ukufudumala futhi azihlanganise. Yingakho kuphakama le heterogeneity ungqimba avikelayo, futhi kungenzeka sidilike.

Ngaphambi zisebenza ilangabi cishe yizona ezisetshenziswa kabanzi ukwakheka for ebusweni metal kumele primed izindlela elicacisiwe yokusetshenziswa. Ngaphezu kwalokho, lokhu izidakamizwa kumele athobele isitifiketi sokuphepha umlilo. Ungakhohlwa ukuthi primer singasebenza ebusweni, bahlanza of upende omdala noma ukungcola.

plasters Fire-cishe yizona ezisetshenziswa kabanzi

Modern ezigcwele emakethe umkhiqizo ezifana stucco refractory. It has a eziphansi, isivuno high lunikeza ukulondeka kanye ukumelana ubudlova imvelo. Nokho, uhlelo lwayo lokusebenza likwazi nezihibe:

• esinjalo.-ejenti ukwelashwa surface kudinga isikhathi nomzamo owengeziwe ngokomzimba.
• Ebusweni kumele embozwe anezikhala kwagcizelela noma kakhonkolo ezindongeni ngeke uhlale isikhathi eside.
• Uhlaka silinganiso kwandisa umthwalo ukwakhiwa isisekelo, engesiyo nomthelela omuhle isimo isakhiwo njalo.
• Lapho isetshenziswa olukhonkiwe izingoma anticorrosive kumele kusetshenziswe, okuyinto kwandisa izindleko le nqubo.

Plasters zisetshenziswa kuphela ezindaweni lapho nomswakama ingeqi 60%.

Mayelana nomkhosi wokuhlanganisa nesifiso sokukuqeda isisindo enamathela ovikelayo plasters engasindi zenzelwe ezingesiyo eliphansi in Ukuvikelwa izinga. Ubuchwepheshe banamuhla buye bavunyelwe ukuthola olukhonkiwe, equkethe Gypsum, lime futhi waterglass, kodwa buyimfanelo enamandla okusezingeni eliphezulu futhi adhesion ezinhle.

Esimweni lapho udinga ukudala okhangayo ukubonakala ibhilidi noma ukuvikela retardants ilangabi emiphumeleni endaweni enobudlova, bavunyelwe kokuqeda putties noma upende.

abakhiqizi Iningi ilangabi retardants eyaziwa

Sekuyisikhathi eside Abakhi upende izinto kushintshwe uhlu lwabo intengo futhi wanezela ilangabi retardants kuwo. Lokhu kusebenza kuzo zombili izinkampani zakwamanye amazwe, kanye nokuphila kwethu uqobo, lwendabuko.

Ngaphansi lokuhweba Interpon zikhiqiza eziphikelelayo kakhulu futhi ephumelelayo umlilo cishe yizona ezisetshenziswa kabanzi upende. Inkampani Nullifire Ltd uzama ukugcina ukunikela upende sokuvikelwa metal, ukhonkolo kanye okwakhiwa ngalo la mabhodi.

Kusukela izinkampani zasekhaya kufanele ukhulume JSC "Euro-isitayela". Lezi zithako akhiqizwa ubucwepheshe bakamuva European, izimpawu ukusebenza high. Ungakhohlwa mayelana NGO "Polimerstroyservis", LLC "Croze" iphrofayela "transformer", NPF Laboratory ukuvikelwa umlilo abanye.
