I-Triphenyl bismuth (TPB) isetshenziswe njengesikhuthazi sokupholisa se-HTPB propellant. I-TPB inganciphisa izinga lokushisa lokupholisa futhi inciphise isikhathi sokupholisa se-propellant, futhi ayinawo umphumela omubi ekusebenzeni kanye nezimpawu ze-mechanics. Umthamo we-TPB ungu-0.006%-0.05% wesisindo esiphelele se-propellant. Isikhathi sokupholisa siyisonto ku-50℃. I-TPB ingasetshenziswa futhi njengesikhuthazi se-polymerization ye-ethyne ibe yi-cyclooctatetraene, i-formaldehyde, i-ejenti yokupholisa yama-polycyclochlorides, namanye ama-monomers njll.
Ukupakisha:Ikesi lepulasitiki eliqinile, elivaliwe, eliyi-cycloidal. Isisindo esiphelele singama-500g noma ama-1000g ngebhodlela ngalinye. Ukupakisha kungalungiswa ngokwezicelo zamakhasimende.
Isitoreji:Igcinwa endaweni epholile, enomoya opholile. Isikhathi sokuphila seshelufu siyizinyanga eziyi-12 kusukela ngosuku lomkhiqizi. Isatholakala uma imiphumela yokuhlolwa kabusha iqinisekisiwe ngemva kosuku lokuphelelwa yisikhathi.
Ezokuthutha:Kufanele kuvimbele imvula ukuthi imanzi, ilanga liphume kanye ne-ultraviolet ngesikhathi sokuthuthwa. Gcina kude nama-oxidants anamandla.
Imiyalelo yokuphepha:Ubuthi ngokugwinya kanye nokuphefumula. Ukuthintana kwamehlo nesikhumba kungabangela ukuvuvukala. Ukusebenza kumele kufakwe amagilavu erabha, umshini wokuphefumula kanye nesivikelo samehlo ngokugqoka izingubo zokuzivikela.
