SNIP: Ukuvikelwa umlilo izakhiwo steel. Fire ukumelana metal izakhiwo ngaphandle ukuvikelwa umlilo

Ukuvikelwa Fire metal izakhiwo liyisici, okuyinto kunenzuzo ezimweni eziningi, wenza ukugxila. Kulokhu, udinga ukuqonda kahle ukuthi kuyini nokuthi lapho idingeka khona.

Kuqakatheke ngani?

imishayo Ukunikeza, mina-imishayo, amakholomu kanye nezinye izakhi ezimweni umlilo singaziphatha ngokungathi cishe ezingalindelekile. Akufanele sibakhohlwe ukuthi umsebenzi wabo oyinhloko ukwenza injongo yayo ngqo - ukugcina isakhiwo eside ngangokunokwenzeka, sigweme noma ikuphi ingozi wokugoqa.

Metal azigcina inqaba yalo ncamashi kuze kube isikhathi lapho izinga lokushisa lokushisa kuma. Abaningi abawazi leli qiniso. Futhi uma ibekwe endaweni okushisa aphakeme, kuyoba nezimo nabalolongeka ngokuhamba kwesikhathi. Ngakho-ke, uma ungasebenzisi ezikhethekile ukuvikelwa umlilo izakhiwo steel emlilweni, ngeke lihlale ngisho 3-5 imizuzu.

Elicibilikile izimisele, kudala umonakalo ukuklanywa kwezakhiwo kanjalo nezinhlaka, abangela ukuwa, lapho abantu abangazange okwamanje bashiye ngokugcwele. Kuyinto, ngokufanele, ujikela kwaba sekufeni kwabo. Kungenxa yalesi sizathu, ukuvikelwa umlilo metal izakhiwo ingenye izakhi ezibaluleke kakhulu ukuthi ungene inqubo yokuthuthukisa amakhono nokuvikeleka isakhiwo ngasinye. Nokho, kungase kudingeke uqonde kahle it unikezwa kanjani futhi nini.

Kuyini lokhu?

Okulandelayo sibheka uma kungenzeka abantu bavikelekile ezingozini zomlilo metal izakhiwo. Kuze kube manje, thina wasebenzisa izindlela ezihlukahlukene ukwakhiwa ngawo abantu bavikelekile ezingozini zomlilo inikezwa, ezifana ulwelwesi izitini, usimende phezu grid futhi abaningi abanye, kodwa kulokhu sicabangela non-kwesakhiwo non ubuchwepheshe kucatshangelwe yinoma yimuphi abaklami abaklami.

Indlela luyasetshenziswa?

Ngokusho ukuvikelwa SNIP umlilo metal izakhiwo endaweni yokuqala kufanele olunikezwa izakhiwo kanye nezinhlaka lapho izakhi ezihlukahlukene metal eziveza zivuliwe. Kulokhu, akukho kungenzeka ngokuvamile evaliwe noma kusetshenziswe design Yiqiniso wezakhiwo yabo. Ngakho, sinesakhiwo ongazange ivikelwe nganoma iyiphi indlela ebizwa metal izakhiwo. Kulokhu, SNIP ukuvikelwa umlilo metal izakhiwo ufezwa lokunameka nabo ezikhethekile umlilo cishe yizona ezisetshenziswa kabanzi upende. Kulokhu, akusiyo kuphela ephumelela kunazo kodwa futhi, ngomqondo obanzi, kuphela indlela.

Kunengqondo ukuphetha ngokuthi yonke into ilula: ukuthenga upende umlilo-cishe yizona ezisetshenziswa kabanzi futhi uyipende ebusweni etholakalayo. Uma uthi nhlá kungase kubonakale sengathi izindlela ezifana ukuvikelwa umlilo metal izakhiwo zingasetshenziswa yinoma abadwebi abavamile noma abasebenzi ezishibhile. Empeleni, lokhu lula kuphela nobumbi ezingabalulekile.

Ukuqinisekisa ukusetshenziswa ngokuphelele lokhu ukuvikelwa umlilo iphrojekthi, kudingeka wazi kahle ukuthi eziningi izingqimba kapende kumele libekwe phezu labo noma ezinye izinto ukubala ukumelana umlilo metal izakhiwo ngaphandle ukuvikelwa umlilo, kanye ukuvimbela ukuthi kungenzeka ngokuhlaziya noma delamination kwezingxenye inqubo yokoma kwamanzi.

design

Ungakhohlwa ukuthi siqu imibala yazo ekhethekile akuzona ezishibhile ngakho. Lokhu nje ingenye yezizathu eziholela ukuthuthukisa iphrojekthi ukunikeza imiklamo abantu bavikelekile ezingozini zomlilo. Nale phrojekthi uzobona indlela ongaphakeme a umkhawulo lomlilo ukumelana metal izakhiwo ngaphandle abantu bavikelekile ezingozini zomlilo kanjani upende kakhulu uzodinga uwakhuphule, kanye zamatshe impahla kufanele usetshenziswe izakhi ezithile.

ochwepheshe Professional benza ukuhlolwa eningilizayo yazo zonke lezi imithwalo ukuthi isinyathelo umklamo othize, ukubala ukumelana umlilo, kanye ngesikhathi lapho bangakwazi ukwenza umsebenzi wabo ngqo ngomlilo. Ngemva kwalokho, le ulahlekile ukubala isikhathi sokubala abazenzi ukushuba edingekayo ungqimba ukuvikelwa. Yilokho okwenza umklamo and definition yentengo umsebenzi, ngemva kwalokho ochwepheshe uqale ukusebenza kohlelo lokulwa.

kuyinto isicelo kanjani?

Izinto khona okuvikela umlilo metal izakhiwo isicelo ngamayunithi airless ezikhethekile. Ngaphezu kwalokho, isicelo sabo kwenziwe kuphela isendlalelo esisodwa eqinile. Isici esiyinhloko lapha wukuthi uma into ilangabi cishe yizona ezisetshenziswa kabanzi sisetshenziswa kakhulu thinly ke uma kukhona omiswe kancane upende iqala ukoma aqhumile, kodwa ngenye nje ngeke isikhathi ukuze ome. Lokhu kuyoholela ekuthuleni liwa off ukwakhiwa. Yingakho kongoti bolwazi ngokuhambisana State Standard (GOST) ukuvikelwa umlilo metal izakhiwo lisetshenziswa kusendlalelo esithile, sebenzi whereupon it unikezwa isikhathi kancane eyomile futhi ungqimba elilandelayo sisetshenziswa ngemuva kwalokhu. Khona-ke, ngokuphinda le nqubo, ukushuba oyifunayo abayifunayo.

Kufanele kuqashelwe ukuthi ungqimba umlilo cishe yizona ezisetshenziswa kabanzi upende ngalinye ngeso elibukhali nje kuphela kodwa futhi ezimanzi ku ezomile ezisalayo kanye ukuncipha Coefficient uyahlolwa. Ngaphezu kwalokho, ungqimba ezomile nalo ilawulwa esebenzisa ezikhethekile kagesi eddy geji. Uma ukhona ngempela ikhwalithi kanye nokusebenza efanele yonke spectrum we izinqubo ezidingekayo, kusukela design ziphethe isicelo ngqo indaba, ekugcineni lokunameka ingahlala iminyaka engaphezu kwamashumi amahlanu.

imphawu letibalulekile

insimbi isakhiwo yabo abasakwazi nozwelo umlilo futhi amazinga okushisa aphakeme ngokomthetho. Yingakho zonke izinqubo abazenzi kuphela ngokuhambisana isethi kusengaphambili imithetho (i-joint venture). Ukuvikelwa Fire metal izakhiwo kumele kwenziwe lokhu ngesizathu sokuthi bathi kwensimbi ngokwayo ukufuthelana ngokushesha okukhulu. Lokhu kuholela ekuncipheni okukhulu ngamandla izakhiwo. Mayelana yokuthi metal kukhona isici abasengozini enkulu kunoma yiliphi ibhilidi emlilweni, nokuthi unikezwa iqiniso lokuthi ngokuvamile usetshenziselwa ukwakhiwa zanamuhla cishe yonke.

Bambalwa abantu ukuqonde ukuthi Uhlaka lwensimbi umlilo ukumelana ngokwanele ongaphakeme nokubaluleka kwalo nxazonke 0.1-0.4 amahora, futhi ngokuhambisana kwezinkambiso ekhona nomlilo isiphi isakhiwo isakhiwo kufanele kube esifundeni 0.5-2.5 amahora kuye ngokuthi ngokuqondile uhlobo isakhiwo, yingakho edingekayo ukuvikelwa umlilo metal izakhiwo. Nokho, izimfuneko isicelo zezinto zokusebenza ezinjalo kahle ukuphatha ukusebenza kwabo futhi uvumele ukuba enze kanjalo, okwamangaza bagcina empeleni ephethwe ukuze athole imiphumela kunesidingo.

izizathu

Ingqikithi ukuvikelwa umlilo izakhiwo steel iwukuba phezu kwensimbi ukudala ezikhethekile sesikrini ukushisa-nangokuvikela. Umzimba womuntu ungakwazi ubambe lokushisa eliphezulu, futhi futhi ayivumeli umlilo ukwenza indaba, uma kunesidingo. Le nqubo kakhulu kubambezela esibukweni amalahle izakhiwo metal uma kwenzeka umlilo. Lokhu kwenza kube isikhathi kwadingeka kwezinhlelo esiphuthumayo okwengeziwe nokusindisa ukuphila kwabantu abaningi.

Zikhona izindlela eziningi okwenziwa abantu bavikelekile ezingozini zomlilo metal izakhiwo. I izingoma zisetshenziswa yizindlela ezivamile ezifana ukhonkolo izindonga nezixazululo ezikhethekile, ukhonkolo noma wokwakha Imbondela, futhi zanamuhla, ngokusekelwe ukusetshenziswa lokubolekwa engasindi futhi izinto, kuhlanganise amaminerali uvolo, Perlite enwetshiwe noma izinto ezihlukahlukene olubamba ukushisa. Intengo yale nqubo kuxhomeke ngqo ekutheni indlela ethile iye yasetshenziswa kanjani esimweni esithile.

Ukwahlukaniswa izindlela

Bezakhiwe ukuvikelwa umlilo metal izakhiwo eyenziwe izindlela eziningana zanamuhla:

• Special fireproofing enamathela. Zenziwa kasimende, amanzi ingilazi nokumbiwa fibre granulate.
• Isicelo Intumescent umlilo cishe yizona ezisetshenziswa kabanzi uveza yazo zonke izinhlobo, okuyizinto uhlelo ngempela eziyinkimbinkimbi ukuthi kuhlanganisa izingxenye organic wezinto ezingaphili. Isenzo sabo esiyinhloko kusekelwe ngokuphelele ukubunjwa ukuvuvukala ngaphansi lokushisa eliphezulu futhi kamuva ukwakheka ukushisa nangokuvikela ungqimba ukungena nakwamanye amazwe kabani ukujiya kuyinto ngamasentimitha ambalwa nje.

Ukuvikelwa Fire metal izakhiwo ngaphandle ukuvikelwa umlilo ngokwanele ongaphakeme, kodwa ngaleyo ndlela izazi ngaphandle kobunzima uwakhuphule kuya kunenani 0,75-2,5 amahora kuye ngokuthi yiziphi sisetshenziswa ungqimba usimende, kanye upende engangenwa umlilo sisetshenziswa noma enamathela engasindi. Ukusetshenziswa intumescent upende e iningi labantu amacala ingafinyelela umlilo ukumelana izakhiwo amahora angaphezu kwelilodwa nengxenye.

Izici isicelo

Isicelo izinto ezikhethekile zingahlukaniswa izigaba ezine eziyinhloko:

1. Surface nokulungiselela.
2. Priming.
3. Ukusetshenziswa upende okhethekile.
4. Enamathela.

Ngokukhethekile kulokhu kunikezwa ukulungiselela metal evele okunye ukwelashwa umlilo-cishe yizona ezisetshenziswa kabanzi. Lapho kulungiselelwa okungafanele enamathela okwengeziwe kungase nje igoqe ngaphansi isenzo yangaphakathi noma yangaphandle, lapho umphumela umsebenzi kungaba zero. Ekusebenteni, ungathola ngempela ezihlukahlukene zithi okungenzeka evele metal ngaphambi isicelo enamathela ekhethekile, ngisho labo kwezakhiwo sensimbi, okuyinto azikakwazi operation, ngokuhambisana izindinganiso isimo kuchazwe uthi eziyisisekelo ezine.

Ekusebenteni, kwamukelwa kabanzi ukusebenzisa izindlela ezimbili eziyinhloko yokwelashwa - mechanical futhi amakhemikhali. Lokhu kuhilela ukusetshenziswa ezikhethekile nokugqwala converters, kusho ukugeza upende omdala, ngisho nezinye mass abanye. Mechanical ubuchwepheshe obufanayo ihlinzeka ukucutshungulwa ngomshini ngokugcwele noma mathupha. Lokhu uhlanzekile Kwenziwa esebenzisa amathuluzi athile, ukuxubha noma sandblasting, futhi inhloso yayo eyinhloko ukuthola indawo metal ahlanzekile ngokuphelele ukungabi okuphelele kuso kwanoma iyiphi ezinengilazi.

Esinye isinyathelo ozikhethela ekulungiseleleni kungenziwa ngokuthi degreasing ephelele esiqhutshwa nokusetshenziswa kumakhemikhali awuketshezi ezikhethekile organic. Injongo eyinhloko yale nqubo ukususwa ngokuphelele metal ebusweni iyiphi amafutha wezinto ezingaphili noma organic amafutha. Ukusebenza wenziwa ngqo phambi enamathela ungqimba wokuqala sisetshenziswa, futhi ezimweni eziningi kunenzuzo ukuhlanganisa ngayo dedusting yamukelwe.

undercoat

Isendlalelo lokuqala substrate kwanoma iyiphi enamathela ilangabi cishe yizona ezisetshenziswa kabanzi - ke njalo kutsho. Futhi iningi labantu izimo kuvamile ukusebenzisa acrylic, okuyinto kubhekwa enemisebenzi kakhulu. Inkinga enkulu wukuqinisekisa priming Ukuvikelwa anticorrosive of zensimbi adhesion qualitative kwamanzi futhi okwalandela enamathela izingqimba.

Kuyadingeka ukuba asondele kukhethwa phansi kakhulu ngokucophelela, uma kuyindodana, okunye ukwelashwa lomlilo cishe yizona ezisetshenziswa kabanzi. Phela, emakethe ungathola eziningi imikhiqizo ehlukene ukuthi ekhiqizwa ngokusho Ukucaciswa, hhayi isivakashi. Ngokuyinhloko nenhlabathi okuyinto akhiqizwa TU, ezahlukene lokushisa ukuthambisa at 90-100 ^{° C,} kanti ukushisa yokusebenza umgwengwezi ilangabi cishe yizona ezisetshenziswa kabanzi kuyinto 220-250 ° ^C. Ngakho, priming ekugcineni ilahlekelwa impahla yayo ukuthi kungaba avuse eminye ukusonteka futhi flaking kanye enamathela ilangabi cishe yizona ezisetshenziswa kabanzi isicelo. Ngaphezu kwalokho, ukusetshenziswa kwanoma yisiphi analogs yokukhiqiza ezishibhile TU kuphela, futhi kuholele anda omiswe nesikhathi impahla isicelo, kanye nokwehla noma ngisho nokulahlekelwa ingqikithi adhesion we isicelo enamathela umlilo-cishe yizona ezisetshenziswa kabanzi.

Akubona bonke bayaqonda ukuthi kubalulekile ukuba silondoloze inhlabathi yome ngokuphelele ngaphambi kuzosetshenziswa ngqo upende engangenwa umlilo uqobo, njengoba kungenjalo enamathela avikelayo singawathola umane crack ngesikhathi ukusetshenziswa. Isicelo izinto ezikhethekile ukuze ezinengilazi ubudala noma ngaphezulu oyi-primed e opende, kungukuthi Kunconywa yizimboni ilangabi cishe yizona ezisetshenziswa kabanzi upende angase kamuva avuse Ukuwohloka adhesion futhi kuya- noma uyaxebuka umgwengwezi.
