Dab tsi yog hom hluav taws kub- iav tiv taus?

Hluav taws kub- iav tiv taus yog ib hom iav tshwj xeeb uas muaj qee yam hluav taws kub ua haujlwm (kev tiv thaiv hluav taws kub thiab hluav taws kub rwb thaiv tsev).

 

Tam sim no muaj hluav taws kub- iav tiv thaiv muaj xws li siab -lub zog monolayer hluav taws- iav tiv thaiv, aluminosilicate hluav taws- iav resistant, borosilicate iav,

 

microcrystalline hluav taws- iav resistant, laminated composite hluav taws- iav resistant, thiab cam khwb cia- nyob rau hauv - qhov hluav taws kub sib xyaw- iav resistant.

 

 

Qhov hluav taws kub- iav tiv thaiv tau faib li cas?

 

Tus qauv GB 15763.1-2019, "Safety Glass for Buildings Part 1: Fire-}resistant Glass," faib cov iav tiv thaiv hluav taws raws li hauv qab no:

 

(1)Raws li cov qauv, nws tau muab faib ua monolayer hluav taws- iav resistant (DFB) thiab hluav taws kub sib xyaw- iav resistant (FFB).

 

• Tib qhov hluav taws kub- iav resistant (DFB) yog ib hom iav tshwj xeeb uas tsim los ntawm ib txheej ntawm iav thiab ua tau raws li cov kev ntsuas hluav taws kub sib xws;

 

• Composite fire- iav resistant (FFB) yog ib hom iav tshwj xeeb uas muaj ob lossis ntau txheej iav los yog ib txheej ntawm iav thiab cov ntaub ntawv organic, thiab ua tau raws li qhov yuav tsum tau muaj kev ntsuas hluav taws kub sib xws.

 

(2)Hluav taws kub- iav tiv thaiv tau muab cais raws li nws qhov kev ua tau zoo ntawm hluav taws ua rau peb hom: insulated hluav taws- iav resistant (Class A), tshav kub- hluav taws xob- thaiv hluav taws- iav resistant (Class B), thiab tsis yog -insulated hluav taws- iav resistant (Class C).

 

• Rwb thaiv tsev hluav taws- iav tiv thaiv (Class A) yog hluav taws kub- iav tiv thaiv uas ua tau raws li ob qho tib si hluav taws kub thiab hluav taws kub- tiv thaiv kev tiv thaiv hluav taws (hu ua Class EI hluav taws- iav tiv thaiv hauv European qauv).

 

• Thaum tshav kub kub- hluav taws xob- thaiv hluav taws- iav resistant (Class B) yog hluav taws kub - iav resistant uas ua tau raws li ob qho tib si hluav taws kev ncaj ncees thiab tsis muaj qhov kub hnyiab ntawm qhov yuav tsum tau ua (tus nqi hluav taws kub tseem ceeb ntawm 15 kW / m²) (hu ua Class EW hluav taws- iav tiv thaiv hauv European qauv).

 

• Tsis yog-insulated hluav taws- iav resistant (Class C) yog hluav taws kub- iav resistant uas tsuas yog ua tau raws li qhov yuav tsum tau ntawm hluav taws kev ncaj ncees (hu ua Class E hluav taws- resistant iav nyob rau hauv European qauv).

 

(3)Raws li kev ntsuas hluav taws kub, hluav taws kub- iav tiv taus tuaj yeem muab faib ua tsib theem: 0.50h, 1.00h, 1.50h, 2.00h, thiab 3.00h.

 

 

Hom hluav taws kub li cas- iav resistant feem ntau siv hauv kev tsim kho? Lawv cov hluav taws kub -cov yam ntxwv ua haujlwm tiv taus yog dab tsi?

 

Feem ntau siv hluav taws kub- iav tiv thaiv hauv kev tsim kho muaj xws li siab- lub zog cesium-potassium hluav taws- iav resistant, borosilicate hluav taws- iav resistant, laminated composite hluav taws- iav resistant, thiab cam khwb cia- nyob rau hauv - qhov chaw hluav taws kub .{8}}

 

1. Siab -lub zog cesium-potassium hluav taws- iav tiv thaiv:

 

High-lub zog monolayer cesium-potassium hluav taws- iav resistant yog hluav taws kub- iav resistant tsim los ntawm cov txheej txheem tshuaj thiab lub cev tempering, belongs rau Class C hluav taws kub- iav resistant.

 

2. Borosilicate hluav taws kub- iav resistant:

 

Silicon{0}}raws li iav nrog ntxiv boron oxide, muaj cov coefficient tsawg ntawm thermal expansion. Borosilicate 4.0 hluav taws kub- iav tiv taus muaj qhov sib npaug ntawm kev nthuav dav tsawg dua li ib nrab ntawm cov iav tsev zoo tib yam, tso cai rau nws tiv taus thermal shock ntau dua. Tom qab tempering, nws muaj kev txwv hluav taws ntau dua thiab muaj kev ncaj ncees hluav taws zoo dua, suav nrog Class C hluav taws kub - iav resistant.

 

3. Laminated composite hluav taws kub- iav resistant (hluav taws- resistant zaj duab xis):

 

Laminated iav ua los ntawm ob lossis ntau txheej ntawm iav thiab hluav taws kub- cov yeeb yaj kiab resistant. Thaum muaj hluav taws kub, qhov hluav taws kub - cov yeeb yaj kiab tiv taus sai sai thiab nthuav dav los ua ib txheej txheej insulating ua npuas ncauj uas thaiv cov cua sov. Thaum tawg los ntawm hluav taws, hom hluav taws kub no- iav tiv taus tuaj yeem ua ke los ua kom nws txoj kev ncaj ncees thiab raug cais raws li Class A hluav taws- iav tiv taus.

4. Pouring -nyob rau hauv hluav taws sib xyaw- iav resistant (hluav taws kub- retardant gel):

 

Hom no muaj ob lossis ntau txheej ntawm cov iav tempered, kaw nyob ib ncig ntawm cov npoo nrog cov nplaim tshwj xeeb- cov kab hluav taws xob retardant, nrog hluav taws kub - cov nplaum nplaum rau hauv qhov chaw. Tom qab kho, nws tsim ib gel-zoo li pob tshab nplaum uas khi rau iav. Thaum raug hluav taws kub, cov gel- zoo li pob tshab nplaum sai sai nthuav dav thiab tawv, ua kom muaj hluav taws kub tsis zoo- tiv taus thiab kub hnyiab tau - insulating board. Qhov no tiv thaiv kev sib kis ntawm cov nplaim taws thiab tseem tiv thaiv qhov kub thiab txias los ntawm kev ua rau sab tsis raug. Nws raug cais raws li Class A lossis Class B hluav taws kub- iav resistant.
