Pwodwi entwodiksyon nan aSingle Burning
Item nan yon sèl Burning (SBI), se yon metòd pou tès pou detèmine reyaksyon an ak konpòtman dife nan bilding pwodwi (eksepte sol) lè ekspoze a atak la tèmik pa yon atik boule sèl (yon brûler sab-bwat apwovizyone ak gaz pwopàn). se echantiyon an monte sou yon Trolley ki positionné nan yon ankadreman anba yon sistèm tiyo echapman. se reyaksyon an nan echantiyon yo nan brûler a kontwole instrumentally ak vizyèlman. Chalè ak lage lafimen pousantaj yo mezire instrumentally ak karakteristik fizik yo evalye pa obsèvasyon.

6.The sistèm lafimen echapman va lafimen kontinyèlman echapman nan vitès la nan 0.50m3 / S-0.65 m3 / s, yo epi yo dwe réglementées pa konvèsyon frekans;
7.Mass koule kontwolè, mezire ran de 0g / s-2.5 G / s, li presizyon nan pa mwens pase 1.5%;
Ka 8.Gas rezèv ap otomatikman kontwole koule pousantaj de 647mg / s ak 2000mg / s, sistèm kontwòl la gaz ka garanti vitès la nan ekipman pou gaz nan pwosesis la nan chanjman tès pa ta dwe depase 5mg / s, asire pwodiksyon an chalè nan 30.7 + 2kW;
9.The fwit chemine sistèm pran echantiyon gaz konsiste de yon filtre sann dife, yon pèlen frèt, de kolòn siye, yon ponp pran echantiyon ak yon ponp news, se konsa yo nan efektivman fè gaz echantiyon pwòp epi sèk;
10.Paramagnetic oksijèn analyser, mezire ran de 0-25%, mezire konsantrasyon oksijèn nan gaz la, seri a konsantrasyon nan 0-25%, T90 <12 segonn; Ki pa Peye dispèrsif enfrawouj CO2 analyser: CO2: 0 ~ 10%;
11.A tiyo ki gen yon longè 2155mm, te ekipe ak yon bagay presyon, twa tèrmokoupl, se yon pwofonde pran echantiyon gaz, ak yon sistèm limyè blan;
12.Two-fason pwofonde, ak seri a nan omwen (0-100) PA ak presizyon nan 2Pa Capteur presyon Inlet konekte. Lè a repons nan pwodiksyon 90% presyon an Capteur se nan pi 1S;
13.The sistèm limyè se tip enkandesan, ak (2900 + 100) tanperati koulè K, epi li se jwenti a fleksib enstale sou bò a nan tiyo a tiyo echapman;
14.Silicon fotodyod detektè, ak 0.1% lineyè estabilite;
Se 15.The lè yo te entwodui nan tib la bò yo kenbe lapwòpte a nan aparèy la optik, ki ka akonpli pa konprese lè;
Application:It is suitable for the testing the fire resistance of building materials / products in single burning item (SBI).
