Cov tshuaj catalyst kho propellant
Triphenylphosphonium (TPB) yog siv los ua cov tshuaj kho rau cov roj propellant uas kub hnyiab heev. TPB tuaj yeem txo qhov kub kho ntawm cov roj propellant thiab ua kom lub sijhawm kho luv dua, thiab nws tsis muaj kev cuam tshuam tsis zoo rau cov khoom ua thiab cov khoom siv kho tshuab. Qhov ntau npaum li cas ntawm TPB yog 0.006% -0.05% ntawm tag nrho cov roj propellant, thiab lub sijhawm kho yog 50 ° C. 7 hnub
Cov tshuaj catalyst polymerization monomer
Siv ua tus catalyst rau polymerization ntawm acetylene rau hauv cyclooctane tetratin, ib qho formaldehyde polymerization catalyst, ib tug curing agent rau polycyclochloride, ib tug catalyst rau polymerization ntawm qee lwm yam monomers, thiab lwm yam.
