Koj ua li cas thiaj paub qhov ntsuas hluav taws kub ntawm cov nplaim hluav taws retardant ntaub?

Oxygen Performance index nrhiav kom tau txoj kev: ntaub hlawv, yuav tsum tau siv ntau cov pa oxygen, tsis yog tib yam combustible, cov pa oxygen xav tau los hlawv tsis zoo ib yam, raws li kev txiav txim siab ntawm cov pa oxygen tsawg nyob rau hauv cov txheej txheem ntawm cov khoom combustion, xam lub oxygen Performance index tus nqi ntawm cov khoom, tuaj yeem txiav txim siab qhov kev ua tau zoo ntawm cov khoom siv.

 

Kab rov tav txoj kev thiab ntsug txoj kev yog cov txheej txheem feem ntau ntawm cov khoom siv hluav taws kub ntsuas. Nws lub hauv paus ntsiab lus tseem ceeb yog: kab rov tav lossis ntsug pinch ib sab ntawm cov qauv, ntxiv cov pa roj uas xav tau rau qhov kawg ntawm cov qauv, raws li kev ntsuas ntawm cov kab hluav taws xob hluav taws xob (txoj kev kab rov tav) thiab nplaim hluav taws kub lub sij hawm (txoj kev ntsug) los tawm tswv yim txog cov nplaim hluav taws xob combustion kev ua tau zoo ntawm cov qauv. Kev ntsuam xyuas ntsug yog nruj dua li 45 ° kev taw qhia thiab kab rov tav.Nplaim retardant ntaub manufacturers

 

Vertical method yog muab faib ua txoj kev puas tsuaj ntev, ntsug nplaim hluav taws xob ntsuas kev ua tau zoo, txoj kev ntsuas hluav taws xob ntsug ntsug thiab qhov ntsuas qhov ntsuas qhov ua tau zoo. Vertical txoj kev tuaj yeem siv los ntsuas cov nplaim hluav taws kub ntawm cov khaub ncaws textiles, cov ntaub ntawv zoo nkauj, cov tsev pheeb suab ntaub, thiab lwm yam.Nplaim retardant ntaub manufacturersTilt txoj kev yog tsuas yog siv rau aircraft sab hauv kho kom zoo nkauj daim ntaub; Txoj kev kab rov tav feem ntau yog siv rau matting fabrics xws li ntaub pua plag.Nplaim retardant ntaub manufacturers

Cov nplaim retardant daim ntaub xeem txoj kev yog tsuas yog siv los xyuas qhov kev puas tsuaj ntev, txuas ntxiv combustion lub sij hawm thiab smoldering lub sij hawm ntawm cov qauv. Cov qauv ntawm ib qho me me tau teeb nyob rau hauv qhov yuav tsum tau combustion chamber nrog qhov yuav tsum tau ignition qhov chaw rau 12s. Tom qab tshem tawm qhov hluav taws kub, lub sij hawm combustion tas li thiab lub sij hawm smoldering ntawm cov qauv raug kuaj pom. Tom qab lub smoldering raug tso tseg, qhov kev puas tsuaj ntev yog ntsuas raws li txoj kev tau teem tseg. Feem ntau raws li Teb Chaws Asmeskas ASTMF1358-1995 "textile nplaim taws retardant kev ua tau zoo tus qauv ntsuas txoj kev - ntsug txoj kev" thiab Tuam Tshoj tus GB / T5456-2009 "Textile combustion Performance Vertical direction test specimen flame spread performance" thiab GB5455-1997 "Textile combustion performance test vertical method” thiab lwm yam qauv. Suav teb cov qauv yuav tsum tau txuas ntxiv combustion lub sij hawm ≤5s, smoldering lub sij hawm ≤5s, kev puas tsuaj ntev ≤150mm. Raws li tus txheeb ze txoj hauj lwm ntawm cov qauv thiab cov nplaim, nws yuav muab faib ua ntsug txoj kev, inclined txoj kev thiab kab rov tav txoj kev.

 

Oxygen Performance index yog hais txog qhov concentration ntawm cov pa oxygen hauv cov nplaim hluav taws kub nyhiab rau qhov hluav taws kub. Feem ntau, qhov siab dua cov pa ntsuas ntawm cov ntaub, qhov siab dua cov pa oxygen xav tau los ua kom kub hnyiab, thiab qhov tsawg dua nws yuav ignite; Ntawm qhov tsis sib xws, cov ntaub ntawv oxygen index tsawg, nyob rau hauv qis oxygen concentration tus nqi yooj yim mus txog qhov ignition point. Qhov ntsuas pa oxygen qis dua 21 yog cov ntaub nplaum nplaum, thiab cov pa ntsuas pa saum toj 28 yog cov nplaim hluav taws kub.
