Hauv catalyst, tib neeg ib txwm ntxiv boehmite li phau ntawv , tab sis nws tsis zoo tshwm sim nrog dej. Koj tuaj yeem ntxiv cov kua qaub rau txhim kho viscosity ntawm boehmite li phau ntawv
Qhov hnyav piv
Pseudo-boehmite: dilute nitric acid (1 feem 64% nitric acid: 5 qhov dej, ntim piv): Tianjing hmoov = 100: 40: 3-4
Kev Ntsuam Xyuas Tian Jing hmoov + pseudo-boehmite (tsawg kawg 80 mesh, ntawm chav kawm, qhov zoo dua qhov zoo dua, tab sis nws nyuaj heev rau sieve, hehe)
Ntxiv nitric acid, ntxiv rau nws maj mam, ntxiv nws thaum siv cov pas me me (saib koj loj npaum li cas, qhov no concentration ntawm nitric acid tsis muaj teeb meem nrog koj txhais tes). Do kom zoo, nyem
Xaws cov khaub hlab ua ntej, tom qab ntawd muab cov ntawv sib xyaw, npog cov phuam ntub dej, thiab “sawv” ib pliag zoo li hnab mij. Tom qab hais txog 30 feeb, thawj zaug siv koj lub khob noom cookie ua neej zoo li lub ntsej muag ib ntus (vim tias Boehmite thiab thixotropy tom qab kua qaub, cov txheej txheem no tseem ceeb heev), kom txog rau lub khob noom cookie ua muag muag thiab tsis lo ntau, Nws yog npaj txhij.
