I-intumescent encane yokuvikela umlilo noma ayi-intumescent

I-Intumescent coating engashi

Ingahlukaniswa ngezigaba ezimbili ezisekelwe ku-solvent-based and water-based, izinhlobo ezimbili zezingubo ezikhethwe izingxenye zomlilo zifana ngokuyisisekelo, ngakho-ke kunzima ukusho ukuthi ungakanani umehluko ekusebenzeni kwabo komlilo, i-solvent ekhethiwe ukusebenzisa ifilimu. -ukwakha izinto. Izinto ezakha ifilimu ezincibilikisa umlilo ezisekelwe ku-solvent ngokuvamile zikhethwa irabha ene-chlorinated, phezu kwe-lv vinyl, ama-amino resins, ama-phenolic resins, njll., ukusetshenziswa kwezinyibilikisi ze-spray peyinti nokunye. Izinto zokwakha ifilimu ezisekelwe emanzini ezingashi.

I-non-intumescent engangenwa umlilo

I-coating ngokuyisisekelo ayishintshi ivolumu lapho ibhekene nomlilo. Ikakhulukazi, ukugqoka ngokwawo akushi noma akushi, okungavimbela ilangabi ukuthi lingasakazeki, futhi ukumboza kungabola amagesi angashi ngaphansi kwesenzo sokushisa okuphezulu noma ilangabi lokunciphisa ukuhlushwa komoya-mpilo kanye namagesi avuthayo emoyeni, ukuze uvimbele ngempumelelo noma ubambezele ukusha. Ngaphezu kwalokho, ukumbozwa emazingeni okushisa aphezulu noma ngaphansi kwesenzo selangabi kungakha ungqimba oluvikelayo olungashi njengeqhwa elimboza ingaphezulu le-substrate evuthayo ukuze lihlukanise i-substrate evuthayo kanye nokuxhumana komoya-mpilo, ukuze ugweme noma ukunciphisa ukuvela kokusabela komlilo, futhi esikhathini esithile ngezinga elithile lokushisa okushisayo.

Ngokusho kwendlela yokuvimbela umlilo, ihlukaniswe yaba yi-intumescent kanye nesakhiwo sensimbi esingafaki umlilo; I-non-intumescent steel isakhiwo esingenamlilo i-coating ibhekisela esakhiweni sensimbi esinamathelayo esingashisi ukuthi i-coating ayikhuli futhi igwebu ekushiseni okuphezulu, futhi iba ungqimba oluvikela umlilo oluvimbela ukushisa nokushisa ngokwalo.

Ngokwezinga lakamuva likazwelonke le-GB14907-2018, okusekelwe emanzini/okuncibilikisiwe okungeyona intumescent okujwayelekile/okukhethekile kwesakhiwo sensimbi esingashi. Ugqinsi olunamathelayo lwesakhiwo sensimbi esingashisi umlilo akumele lube ngaphansi kuka-15㎜.

Isakhiwo sensimbi esingeyona intumescent esingenamlilo esinamathelayo isimiso sokushisa umlilo siwukuthi ukugqoka ngokuyisisekelo akushintshi ivolumu lapho kushiswa umlilo, kodwa ukuqhutshwa kokushisa okushisayo kuphansi kakhulu, okubambezela ijubane lokudlulisa ukushisa ku-substrate enomshwalense, futhi ukumbozwa kwengubo yomlilo ngokwayo akushisi, futhi kusebenza njengesithiyo futhi kuvimbela imisebe yokushisa yezingxenye zensimbi, okuvimbela ilangabi nokushisa okuphezulu ekuhlaseleni ngokuqondile izingxenye zensimbi.  

Kukhona ezinye izingxenye in the enamathela ukuthi basabela nomunye uma umlilo ukukhiqiza umzimba non-gas kuyinqubo ukusabela ukumuncwa ukushisa, kodwa futhi idla ukushisa okuningi, okuyinto evumela ukwehlisa izinga lokushisa uhlelo, kanjalo. umphumela wokuvimbela umlilo uyamangalisa, futhi udlala ukuvikelwa komlilo okuphumelelayo kakhulu nokuvikelwa kokushisa okushisayo kwensimbi. Ngaphezu kwalokho, lolu hlobo lwensimbi oluvikela umlilo lufakwa ngaphansi komlilo lapho i-coating ishintsha ukuze yenze ungqimba olucwebezelayo oluvikelayo, olungadlala indima ekuhlukaniseni umoya-mpilo, ukuze umoya-mpilo ungavikelwa into evuthayo.

I-WBM-01 yohlobo lokuqeda lwemiyalo yokwakha enamathela ekushisweni kohlobo lokuqeda ukunamathela okungashi ukunamathela kwesakhiwo sokhuni esisekelwe emanzini, ngokuhlolwa kwe-"National Quality Supervision and Inspection Center for Fixed Fire Extinguishing Systems and Fire-Resistant Components", ukuhlolwa ngokomzimba namakhemikhali. izakhiwo ezijwayelekile, ukusebenza komlilo kwezinga lokuqala. Izinkomba zokusebenza kobuchwepheshe zomkhiqizo zihambisana nezinga le-GB12441-2005. Ngokusebenzisa izinto zokusetshenziswa eziphambili kanye nezinqubo ezikhethekile zokukhiqiza, isikhathi sokumelana nomlilo ≥ imizuzu engu-20, ukufeza izindinganiso zikazwelonke, lapho ilangabi livutha kupende, ukwakheka kongqimba lwamalahle oluyi-spongy ku-substrate kunokupholisa okushisayo nokuhlukaniswa kwe-thermal insulation. indima yomoya, enganciphisa ijubane lokusabalalisa ilangabi ebusweni bezinto eziboshwe, ukuvimbela ngokuphumelelayo ukusakazeka komlilo ngokushesha ukuvimbela ukushiswa kwezinkuni ukufeza injongo yokushisa. I-coating kapende, igwebu futhi inwebeka uma kwenzeka umlilo, yakha ungqimba olufana nesipontshi lokuvala umlilo kanye nokuhlukaniswa komthombo womlilo, ingavikela ngempumelelo isisekelo esivuthayo ngesikhathi esithile, futhi ingasetshenziswa kabanzi ekwakhiweni kwezimboni nezomphakathi zokhuni. izingxenye zesakhiwo, amaphaneli avuthayo kanye ne-flue, imigudu yomoya kanye nokunye ukuvikela umlilo.
