Hluav taws kub Resistance Properties of Magnesium Oxide (MGO) Boards

Magnesium oxide (MGO) boards yog cov khoom siv hluav taws xob zoo tshaj plaws hauv tsev, cais raws liClass A1 tsis yog-combustible(qhov ntsuas hluav taws kub siab tshaj). They deliver excellent fire protection through three core mechanisms: inorganic composition, dehydration & heat absorption, and dense structural stability, achieving a fire resistance duration of 1 to 4 hours. Tsis muaj pa luam yeeb, molten drips los yog nplaim taws kis tau, ua tau raws li qib siab - cov txheej txheem kev nyab xeeb hluav taws.

1. Kev ntsuas kev ua tau zoo

Suav Standard (GB 8624-2012): Class A1 Tsis yog-combustible

Tsis muaj hluav taws kub hnyiab los yog nplaim taws ntawm 750℃rau 30 feeb

Tag nrho cov nqi calorific: Tsawg dua los yog sib npaug rau 1.5 MJ / kg (tsis pom zoo combustion zog)

Kev haus luam yeeb toxicity: Qib ZA3 kev nyab xeeb theem (FED Tsawg dua lossis sib npaug rau 0.5)

Tsis muaj molten drips los yog nplaim propagation

Siab -kub tsis kam:

Tseem tsis yog-flammable, tsis-shrinking thiab tsis- tawg ntawm 800 degree

Tsis muaj nplaim taws, tsuas yog me ntsis carbonization ntawm 1200 degree

Melting point ntawm magnesium oxide (MgO): 2852 degree, nrog kev ruaj khov heev

2. Cov Ntsiab Cai Hluav Taws Xob Hluav Taws Xob (Peb Nplaim-Cov Txheej Txheem Ua Tsis Zoo)

Inherently Tsis yog -combustible Inorganic FormulaCov ntaub ntawv hauv paus: Magnesium oxide & magnesium chloride (tag nrho inorganic); Txhim kho nrog alkali-resistant fiberglass mesh. Tsis muaj cov organic combustible tshuaj, tshem tawm cov phom sij txaus ntshai.

Lub cev qhuav dej & cua sov nqus rau cua txias & hluav taws thaivCrystal dej tso tawm nyob rau hauv qhov kub thiab txias nrog endothermic cov tshuaj tiv thaiv, absorbing loj heev kub los ntawm hluav taws scenes. Dej vapor tsim ib txheej insulating kom cais cov pa oxygen thiab nplaim taws.

Cov qauv kev ruaj ntseg ntawm qhov kub siab heevSolidified rau hauv ntom 3D magnesium oxychloride siv lead ua qauv. Fiberglass reinforcement tiv thaiv kev tawg thiab tev nyob rau hauv high tshav kub, tswj cov txheej txheem kev ncaj ncees, thermal rwb thaiv tsev thiab load- bearing muaj peev xwm.

3. Lub Sij Hawm Hluav Taws Xob Hluav Taws Xob ntawm Cov Khoom Siv Hluav Taws Xob

6mm ib lub rooj tsavxwm: Ntau dua lossis sib npaug rau 2-teev hluav taws kub tiv thaiv rau phab ntsa

12mm ob npaug -sided board: Ntau dua lossis sib npaug rau 4-teev hluav taws kub tiv thaiv rau phab ntsa

Hluav taws kub qhov rooj cores & hluav taws ducts: 1-3 teev hluav taws kub tiv thaivKey fire resistance indicators:

Kev ncaj ncees (E): Tsis muaj nplaim taws nkag mus rau sab tsis pom

Thermal rwb thaiv tsev (I): Qhov kub thiab txias ntawm qhov tsis pom kev tsawg dua los yog sib npaug li 140 degree

Load-cov kabmob muaj peev xwm (R): Tsis muaj kev sib tsoo lossis deformation hnyav

4. Superior Fire Safety Advantages

Toxic-tsis muaj pa luam yeeb: Tso tawm tsis muaj CO, HCN, formaldehyde lossis lwm yam roj teeb tsis zoo thaum hlawv

Tsis muaj molten drips: Tsis muaj ignitable ntog tshuaj tiv thaiv hluav taws

Cov pa luam yeeb tsawg: Pom kev pom tseeb hauv hluav taws kub ceev kom muaj kev nyab xeeb khiav tawm

Moisture- tiv taus hluav taws: Kev ua tau zoo ntawm hluav taws tseem nyob ruaj khov nyob rau hauv siab -cov av noo ib puag ncig yam tsis muaj deliquescence lossis deformation

Ntev -lub sij hawm durability: Kev laus thiab corrosion yuav tsis muaj zog tiv thaiv hluav taws

5. Cov xwm txheej ntawm daim ntawv thov

Hluav taws xob faib phab ntsa, firewall panels, fireproof qab nthab boardsFire qhov rooj cores, hluav taws kub cua ducts, cable wrapping protectionHospitals, tsev kawm ntawv, khw malls, tshuab chav, tunnels, purification rhiavSteel qauv hluav taws kev tiv thaiv, lub teeb yuag hluav taws rwb thaiv tsev systems

6. Kev sib piv ntawm hluav taws kub nrog cov pa roj carbon monoxide

MGO Board: Chav A1 tsis yog-combustible, 1-4 teev hluav taws kub, tsis muaj pa luam yeeb & tshuaj lom, tsis muaj drips

Gypsum Board: Chav B nplaim hluav taws- retardant, ~ 30 feeb hluav taws tsis kam, tsis muaj zog ntawm qhov kub thiab txias

Calcium Silicate Board: Chav Kawm A2 tsis yog -combustible, ~ 1 teev hluav taws kub, tsis tshua muaj zog

7. Cov lus qhia txog kev yuav khoom kom ntseeg tau tias muaj hluav taws kub

Txheeb xyuas cov ntaub ntawv qhia txog hluav taws kub hauv chav A1 ib GB 8624

Cov ntsiab lus chloride ion tsawg dua los yog sib npaug li 8% (tiv thaiv deliquescence, xyuas kom siab -qhov kub thiab txias)

Ceev: 1.2–1.8 g / cm³ (siab dua=hluav taws kub rwb thaiv tsev zoo)

Nruab nrab / tsis yog -alkali fiberglass mesh (tiv thaiv -corrosion nyob rau hauv qhov kub thiab txias)

Cov ntsiab lus

NrogChav Kawm A1 tsis yog- qhov ntsuas hluav taws xob, 1-4 teev hluav taws kub tsis kam, tsis muaj pa luam yeeb thiab zoo heev - qhov kub thiab txias, MGO boards yog qhov kev xaiv zoo tshaj plaws rau lub tsev fireproofing, tshwj xeeb tshaj yog rau cov pej xeem venues uas yuav tsum tau nruj hluav taws kev nyab xeeb thiab siab pedestrian flow.
