Muyezo wa akuluakulu:GJB 5276-2003
CAS RN:603-33-8
1. Kapangidwe ka thupi ndi mankhwala:
1.1 Fomula ya molekyulu: C18H15Ndi
1.2 Kulemera kwa Mamolekyulu: 440.3
1.3 Kusungunuka: Sisungunuka m'madzi, koma imasungunuka mu anhydrous alcohol ndi n-heptane.
1.4 Kukhazikika ndi kuchitapo kanthu: Kukhazikika pa kutentha kwabwinobwino ndi kupsinjika, koma kumakhudzana ndi chinyezi, okosijeni wamphamvu komanso kuwala kwamphamvu kwa ultraviolet.

Triphenyl bismuth (TPB) yagwiritsidwa ntchito ngati chothandizira kuchiritsa cha HTPB propellant. TPB ikhoza kuchepetsa kutentha kwa kuchiritsa ndikuchepetsa nthawi yochiritsa ya propellant, komanso siiwononga magwiridwe antchito ndi kagwiritsidwe ntchito kake. Mlingo wa TPB ndi 0.006%-0.05% ya kulemera konse kwa propellant. Nthawi yochiritsa ndi sabata imodzi mu 50℃. TPB ingagwiritsidwenso ntchito ngati chothandizira kupopera kwa ethyne kukhala cyclooctatetraene, formaldehyde, chothandizira kuchiritsa cha polycyclochlorides, ndi ma monomers ena ndi zina zotero.
Kulongedza:Chikwama cha pulasitiki cholimba, chotsekedwa, komanso cholimba. Kulemera konsekonse ndi 500g kapena 1000g pa botolo lililonse. Kulongedza kumatha kusinthidwa malinga ndi zomwe makasitomala akufuna.
Malo Osungira:Imasungidwa pamalo ozizira komanso opumira mpweya. Nthawi yosungiramo mankhwala ndi miyezi 12 kuchokera tsiku lopangidwa. Imapezekabe ngati zotsatira zoyesedwanso zikugwirizana ndi tsiku lotha ntchito.
Mayendedwe:Ziyenera kupewa mvula, dzuwa ndi ultraviolet panthawi yoyenda. Sungani kutali ndi ma oxidant amphamvu.
Malangizo achitetezo:Poizoni pomeza ndi kupuma. Kukhudzana ndi maso ndi khungu kungayambitse kutupa. Opaleshoniyo iyenera kuyikidwa ndi magolovesi a rabara, chopumira mpweya komanso choteteza maso povala zovala zodzitetezera.
