Ib suam ntawm hluav taws kub: qhov hluav taws kub hoob kawm ntawv thiab nws cov variants

Niaj hnub no, muaj cov qhia tshwj xeeb uas tsim tus qauv uas tsim lub cim thiab kev kawm ntawv ntawm cov hluav taws kub - GOST 27331-87. Qhov no daim ntawv los mus txiav txim lub variation ntawm lub combustion txheej txheem thiab mus xaiv qhov zoo tshaj txhais tau tias rau extinguishing nws. Nyob rau hauv cov nqe lus ntawm tshav kub thiab huab hwm coj mus nrog cov ib puag ncig hluav taws kub yog nyob rau hauv Certificate thiab nyob rau hauv qhib rau tej qhov chaw. Thiab, nyob ntawm seb lub ntau yam ntawm burning tshuaj thiab cov ntaub ntawv yuav tsum tau muab faib mus rau hauv cov chav kawm ntawv thiab subclasses, uas peb yuav tham nyob rau hauv kom meej nyob rau hauv no tsab xov xwm.

Yuav ua li cas cov chav kawm ntawv raug muab faib ua hluav taws kub?

1) Class A - combustion ntawm khoom combustible cov ntaub ntawv thiab tshuaj. Nyob rau hauv cov ntaub ntawv no, yog hais tias tus smoldering ntoo, textiles los yog daim ntawv, qhov hluav taws kub yog hais txog mus rau lub subclass A1, thiab yog hais tias muaj yog ib tug tsis muaj smoldering khoom, xws li yas, - mus Division A2.

2) Class B roos flammable flammable kua: insoluble - subclass B1, -B2 soluble.

3) Class C hluav taws kub yog txhais los ntawm roj cua.

4) Class D - hlawv hlau. Ntxiv mus, lub teeb co mus rau lub D1 subclass, alkaline denoted D2, ib tug hlau uas muaj compound - D3.

5) Hoob E - hlawv hluav taws xob sib, uas yog nyob rau hauv voltage.

6) Hoob F-hluav taws kub tej twj thiab nuclear cov ntaub ntawv.

hom ntawm cov hluav taws kub

Los ntawm cheeb tsam, qhov hluav taws kub hlawv tag nrho cov chav kawm ntawv yog muab faib rau propagating thiab propagating. Nyob rau hauv tas li ntawd, lawv tej zaum yuav txawv nyob rau hauv loj thiab cov ntaub ntawv kev puas tsuaj yuav tsum tau coob leej ntau tus, piv txwv li nyob rau hauv lub hav zoov, nyob rau hauv loj industrial cov nroj tsuag thiab warehouses nrog combustible cov ntaub ntawv, raws li tau zoo raws li nyob rau hauv qhov kev koom. Cais hluav taws kub tshwm sim nyob rau hauv ib tug cheeb tsam, thaum lub khoom cover ib tug loj tus naj npawb ntawm cov lug thiab txawv kev siv ntawm burning. Nyob rau hauv lub qhaj ntawv ntawm cov cua li lub caij yuav loj hlob mus rau hauv qhov hluav taws kub cua daj cua dub, uas yog tsiag ntawv los ntawm tsim ntawm giant kem turbulent nplaim taws uas tsiv ntawm kev kub ceev.

Breathability thiab hluav taws load

hluav taws kub kawm tswj cua, yus muaj los ntawm ib tug tsawg cov ntsiab lus ntawm cov pa nyob rau hauv ib chav tsev, thaum ib tug dhau heev lawm ntawm combustible cov ntaub ntawv thiab tshuaj. Nyob rau hauv rooj plaub no tus kis ntawm hluav taws nyob rau hauv lub cheeb tsam ntawm huab cua-mov qhov los yog cov pa txaus uas nkag mus rau los ntawm tus neeg kho tshuab cua system. Yog hais tias lub cai hauv tsev ntau heev ntawm cov pa, lub combustion txheej txheem yuav nyob ntawm seb nkaus rau qhov hluav taws kub load. Raws li lawv tsis xws hluav taws cov chav kawm zoo heev rau cov raging hluav taws nyob rau hauv lub qhib.

Volumetric thiab lub zos hluav taws kub

Thaum lub ntim ntawm hluav taws, cua yog tswj, muaj yog khaus thermal ntxim rau cov laj kab. Tej combustion yog yus muaj los ntawm ib tug roj txheej ntawm cov nplaim taws thiab qhov chaw ntawm lub fencing. Tag nrho cov txheej txheem yog nrog los ntawm tshaj oxygen. Thaum cov kev cai ntawm cov hluav taws tsis muaj, haus luam yeeb kev tshuaj ntsuam, raws li ib tug txoj cai, tsis tuaj kawm ntawv.

Cov chav kawm ntawm hluav taws ntws zos, yog yus muaj los ntawm cov uas tsis muaj cua sov rau lub surrounding laj kab. Lawv txoj kev loj hlob nyob rau hauv lub dhau heev lawm huab cua, lub ntau yam ntawm combustible cov ntaub ntawv thiab tshuaj, raws li zoo raws li lawv txoj cai thiab qhov chaw nyob rau hauv lub chav tsev. Nws yog sau tseg hais tias volumetric hluav taws, tsis hais ntawm lawv cov Certificate, hu ua qhib thiab lub zos - private, raws li lawv tshwm sim nyob rau hauv kaw cov qhov rai thiab lub qhov rooj qhib.
