Triphenyl bismuth (TPB) tau siv los ua cov tshuaj kho kom zoo rau HTPB propellant. TPB tuaj yeem txo qhov kub thiab txias ntawm cov propellant thiab txo lub sijhawm kho kom zoo, thiab nws tsis muaj kev cuam tshuam rau kev ua haujlwm thiab cov khoom siv kho tshuab. Qhov ntau npaum li cas ntawm TPB yog 0.006% -0.05% ntawm tag nrho qhov hnyav rau cov propellant. Lub sijhawm kho kom zoo yog ib lub lim tiam hauv 50 ℃. TPB kuj tseem siv tau ua cov tshuaj catalyst ntawm polymerization rau ethyne rau hauv cyclooctatetraene, formaldehyde, tus neeg sawv cev kho rau polycyclochlorides, thiab lwm yam monomers thiab lwm yam.
Ntim:Lub thawv yas cycloidal kaw, tawv, thiab ruaj khov. Qhov hnyav tag nrho yog 500g lossis 1000g rau ib lub raj mis. Kev ntim khoom tuaj yeem hloov kho raws li cov neeg siv khoom thov.
Kev Khaws Cia:Khaws cia rau qhov chaw txias thiab muaj cua nkag. Lub sijhawm khaws cia yog 12 lub hlis tom qab hnub tsim khoom. Nws tseem muaj yog tias qhov tshwm sim rov kuaj dua tau lees paub tom qab hnub tas sij hawm.
Kev Thauj Mus Los:Yuav tsum tiv thaiv kom tsis txhob raug nag los nag, tshav ntuj thiab ultraviolet thaum lub sijhawm thauj mus los. Khaws cia kom deb ntawm cov tshuaj oxidants muaj zog.
Cov lus qhia txog kev nyab xeeb:Tshuaj lom los ntawm kev noj thiab ua pa. Kev sib cuag ntawm qhov muag thiab daim tawv nqaij tuaj yeem ua rau o. Kev ua haujlwm yuav tsum tau nruab nrog cov hnab looj tes roj hmab, lub tshuab ua pa thiab kev tiv thaiv qhov muag los ntawm kev hnav khaub ncaws tiv thaiv.
