Ke eng Liaparo tse Thibela Mollo?

Liaparo tse thibelang mollo ke libopeho tse khethehileng tse sebelisoang holim'a metsi ho ntlafatsa bokhoni ba tsona ba ho mamella mocheso o phahameng le malakabe ntle le ho tuka kapa ho senyeha ka potlako. Ho fapana le lipente tse tloaelehileng, tse ka hotetsang kapa tsa kenya letsoho ho ata ha mollo, liphahlo tsena li entsoe bakeng sa ho mamella mocheso, hangata li fana ka tšireletso e lekantsoeng ka nako e itseng, joalo ka lihora tse peli tlas'a liteko tse tloaelehileng tsa mollo.

Bohareng ba tsona, liaparo tse ngata tse sa cheng li na le monko o monate, ho bolelang hore li ruruha kapa li "itumesce" ha li futhumala. Karabelo ena e etsa hore ho be le char e teteaneng, e kang foam e koalang karoloana, e thibelang phetiso ea mocheso le phihlello ea oksijene. Char e sebetsa e le mokoallo, e senyeha butle-butle ho boloka tšireletso. Mefuta e sa tšoaneng ea li-intumescent, joaloka lipente tse hanyetsanang le mocheso o phahameng, li itšetlehile ka metsoako ea ceramic kapa silicone e thehiloeng ho mamella mocheso o sa khaotseng ntle le ho senyeha.

Likarolo tsa bohlokoa li kenyelletsa li-binders (mohlala, epoxy, silicone, kapa acrylic), li-additives tse thibelang mollo (joalo ka ammonium polyphosphate kapa melamine), le li-filler tse khothalletsang ho thehoa ha char. Lisebelisoa tsena li etsa bonnete ba hore seaparo se lula se tsitsitse mochesong oa tikoloho empa se sebetsa hantle ha ho hlokahala. Lintlha li khethoa ka tlhahlobo e matla, joalo ka UL 263 kapa ASTM E119, moo likopano li pepesetsoang mollo o laoloang ho lekanya nako ho fihlela ho hloleha.

Liaparo tse thibelang mollo li fapane le tse thibelang mollo; ea pele e fana ka tšireletso ea sebopeho khahlanong le ho pepesehela mocheso o phahameng ka nako e telele, athe lelakabe le liehang haholo le hasana linthong tse tukang. Tšebeliso ea tsona ea filimi e tšesaane-hangata e le limilimithara tse teteaneng-e etsa hore e be tse loketseng merero e tsamaisoang ke aesthetics, e kopantsoeng ka mokhoa o tsitsitseng le mehaho.

Ka bokhutšoanyane, liphahlo tsena li fetola libaka tse tlokotsing hore e be lithebe tse thibelang mollo, tse hatisang ho tšoarella le boiketlo ba tšebeliso ea lera le le leng.

 

Mefuta ea Liaparo tse sa Cheng

Liaparo tse sa cheng li fapana ho ea ka sebopeho, ts'ebeliso, le ts'ebeliso e reriloeng, empa boholo ba tsona li oela ka har'a mekhahlelo e sa chesehang.

Liaparo tsa Intumescent: Tsena ke linaleli tsa litekanyetso tsa lihora tse peli. Mefuta e thehiloeng metsing e fana ka likhahla tse boreleli le melemo ea tikoloho, e loketseng tšebeliso ea ka tlung. Mefuta e fapaneng e thehiloeng ho solvent e hanela mongobo, e loketseng tikoloho ea kantle kapa e thata. Li-intumescents tse thehiloeng ho epoxy li fana ka nako e telele bakeng sa maemo a indasteri, li mamella maemo a feteletseng joalo ka mello ea hydrocarbon. Mehlala e kenyelletsa Sherwin-Williams FIRETEX FX6010, e fanang ka lihora tse peli ka tšepe.

Li-Non-Intumescent High-Temperature Coatings: Tsena li mamella mocheso o sa khaotseng ntle le ho atoloha, li sebelisa silicone kapa matrices a ceramic. Lihlahisoa tse kang TEMPERKOTE NO. 450C sireletsa tšepe ea aluminized nakong ea mocheso o phahameng. Omega Fire, khetho e thehiloeng metsing, e mamella 1,200 ° C ntle le ho oa.

Liaparo tsa Hybrid li kopanya likarolo, tse kang epoxy-silicone bakeng sa kutu le ho hanyetsa mocheso. Khetho e itšetlehile ka substrate (tšepe, lehong, konkreite), mofuta oa mollo (cellulosic vs. hydrocarbon), le tekanyo e hlokahalang.

 

Joang Liaparo tse Thibela Mollo Sebetsa

Boselamose bo ka har'a k'hemistri. Bakeng sa li-inttumescents, mocheso o baka karabelo: mohloli oa asiti oa bola, mohloli oa carbon o etsa char, 'me ntho e fokang ea e atolosa. Katoloso e ka fihla ka makhetlo a 10-100 ka botenya ba mantlha, e theha insulation.

Li-non-itumescents li bonahatsa kapa li qhala mocheso ka lisebelisoa tsa refractory. Kopo e otlolohile: fafatsa, borashe, kapa rola jase e le 'ngoe kapa ho feta ho fihlela botenya ba mil bakeng sa tekanyetso. Ho phekola ho tiisa ho khomarela, ka likhetho tse omeletseng ka potlako joalo ka FIRETEX FX6002 e lumellang ho sebetsana ka potlako.

 

Likopo Hohle Liindasteri

Ho tloha ho li-skyscrapers ho ea ho li-rigs tsa oli, liaparo tsena li sireletsa lisebelisoa tsa bohlokoa.

Structural Steel: Thibela ho putlama ha meaho; PPG PITT-CHAR NX bakeng sa likotsi tsa hydrocarbon. Wood le Gypsum: Ntlafatsa likopano ho ea ho litekanyetso tsa lihora tse peli; mohlala, ho I-joists kapa firewall. Spray Foam le Plastics: Fana ka lithibelo tsa mocheso; fokotsa mosi ka har'a litanka tsa indasteri. Lintho tse Khabisitsoeng: Liaparo tse pepenene bakeng sa botle ba lehong.

 

Ho Finyella Tšireletso ea lihora tse peli ntle le ho chesa

Litekanyetso tsa lihora tse peli li bolela ho mamella mollo ntle le ho hloleha ha substrate bakeng sa metsotso e 120. Li-itumescents tse kang FlameOFF Fire Barrier Paint li lumellana le ASTM E119 bakeng sa lihora tse 1-2. FireGuard E-84 e fokotsa ho ata. Kopo e le 'ngoe e lekane ka botenya bo nepahetseng.

 

Lithuto tsa Litaba le Melemo ea Sebele ea Lefatše

Setsing sa tšepe, li-itumescent li ne li sireletsa litanka mollong. Melemo: ho boloka litšenyehelo, aesthetics, bophelo bo bolelele.
