Sodium Thiocyanate: Khemikhale ea Liindasteri e nang le Merero e Mengata
Masimo a Maholo a Kopo
1. Tlhahiso ea Faeba ea Acrylic
Sodium thiocyanate ke thepa ea bohlokoa tlhahisong ea likhoele tsa acrylic. Nakong ea polymerization ea acrylonitrile, sodium thiocyanate e sebetsa e le solvent, e fana ka tikoloho e tsitsitseng bakeng sa karabelo ea polymerization. E qhala li-monomers tsa acrylonitrile ho theha sistimi e ts'oanang ea polymerization, e leng se fellang ka likhoele tsa acrylic tsa boleng bo holimo. Likhoele tsa acrylic li tsebahala ka ho hanyetsa lik'hemik'hale hantle, ho hanyetsa ho tsofala, le ho thibela mocheso, e leng se etsang hore li sebelisoe haholo liaparong, masela a lapeng le masela a indasteri.
2. Reagent ea Tlhahlobo ea Lik'hemik'hale
Sodium thiocyanate e bohlokoa tlhahlobong ea lik'hemik'hale. E ka etsa metsoako e nang le li-ion tsa tšepe tse kang li-ion tsa tšepe, e leng se lumellang ho lemoha le ho hlahloba bongata ba li-ion tsena ka mekhoa ea colorimetric kapa titration. Mohlala, tlhahlobong ea li-ion tsa tšepe lisampoleng tsa metsi, sodium thiocyanate e arabela le li-ion tsa tšepe ho etsa motsoako o mofubelu oa mali. Mekhoa ea colorimetric e ka fumana kapele le ka nepo mahloriso a li-ion tsa tšepe. Mokhoa ona o bonolo haholo 'me o bonolo ho o sebelisa, o etsa hore o sebelisoe haholo tlhahlobong ea boleng ba metsi, tlhokomelo ea tikoloho le taolo ea boleng tlhahisong ea indasteri.
3. Indasteri ea ho Sebetsa ka Metlakase
Indastering ea ho polata ka motlakase, sodium thiocyanate e sebelisoa hangata e le tlatsetso litharollong tsa ho polata ka motlakase. E ntlafatsa ts'ebetso ea lera la ho polata ka motlakase, e ntlafatsa ho tšoana le ho khomarela ha plating, 'me e eketsa khanyetso ea ho bola le boleng ba ponahalo ea lihlahisoa tse polata ka motlakase. Mohlala, ho polata ka motlakase ka koporo, ho eketsa tekanyo e loketseng ea sodium thiocyanate ho thibela hydrolysis ea li-ion tsa koporo, e leng se fellang ka lera la ho polata le boreleli le le ts'oanang le nang le masoba a fokolang le liphoso tsa likoti. Ho feta moo, sodium thiocyanate e ka sebelisoa ho polata ka motlakase litšepe tsa bohlokoa tse kang khauta le silevera, ho ntlafatsa khanya le ho hanyetsa ho tsofala ha plating.
4. Ho kopanya lintho tse phelang
Sodium thiocyanate e sebediswa haholo tlhahisong ya dintho tse phelang. E ka sebetsa e le sesebelisoa sa cyanation bakeng sa tlhahiso ya metsoako e fapaneng ya dintho tse phelang. Mohlala, tlhahisong ya nitriles, sodium thiocyanate e ka arabela le aldehydes kapa ketones ho hlahisa nitriles tse tsamaellanang. Ho feta moo, sodium thiocyanate e ka sebediswa ho kopanya metsoako ya thiourea, e leng ya bohlokwa masimong a meriana, dibolayadikokwanyana le didae. Ho arabela le ho kgetha ha sodium thiocyanate ho etsa hore e be sesebelisoa se sebediswang haholo tlhahisong ya dintho tse phelang.
5. Likopo tse ling
Sodium thiocyanate e ka boela ea sebelisoa masimong a mang. Mohlala, indastering ea ho daea le ho hatisa, e ka sebelisoa e le mothusi oa ho daea ho ntlafatsa ho monyeha le ho potlaka ha lidae. Indastering ea ho etsa pampiri, e ka sebelisoa lits'ebetsong tsa ho soeufatsa le ho tlosa enke ho ntlafatsa boleng le ts'ebetso ea pampiri.
