Mosebetsi le tšebeliso
1. Tlhahiso ea li-antioxidants tsa oli e tlotsang, li-antioxidants tsa polasetiki, li-antioxidants tsa rabara le li-stabilizer tsa phofo ea lithunya. Diphenylamine e sebelisoa haholo masimong ana e le mokhoa oa ho thusa ho ntlafatsa botsitso le ho tšoarella ha thepa.
2. Tlhahiso ea lintho tse kopanyang dae le chefo e bolaeang likokoanyana. Diphenylamine e na le lits'ebetso tsa bohlokoa indastering ea dae, joalo ka ho lokisa dae ea azo le dae tse ling, le bakeng sa tlhahiso ea li-accelerator tsa rabara, li-antioxidants, li-stabilizer tsa polasetiki le meriana ea liphoofolo e kang diphenylamine sulfide.
3. E sebelisoa e le thibelo le retarder ea li-free radical. Ka har'a tlhahiso ea lintho tse phelang, diphenylamine e ka thibela kapa ea liehisa liketso tsa polymerization tse qaliloeng ke li-free radicals, ka hona e laola tsoelo-pele ea liketso tsa lik'hemik'hale.
4. E sebelisoa ho khetholla DNA le li-nitrate. Diphenylamine e boetse e sebelisoa tlhahlobong ea biochemistry le ea lik'hemik'hale, joalo ka ho fumana colorimetric ea li-nitrate, li-nitrite, li-chlorate le magnesium.
5. Mesebetsi e meng: Diphenylamine e ka boela ea sebelisoa e le sesebelisoa sa polokeho bakeng sa nitrocellulose le liqhomane tse se nang mosi, hammoho le sesebelisoa sa ho tlosa mokelikeli.
Ho paka, ho boloka thepa le ho e tsamaisa
1. Lisebelisoa tsa ho paka: Diphenylamine e lokela ho pakoa ka har'a sephutheloana se koetsoeng le se felletseng, ho netefatsa hore sekoahelo sa moqomo se koetsoe, lesale la moqomo le tiile, 'me manonyeletso a' mele oa moqomo a tiile 'me ha a na likheo.
2. Maemo a polokelo:
Mocheso: Boloka ka tlung e pholileng, e nang le moea o kenang, hole le mollo, mehloli ea mocheso, 'me u qobe khanya.
Tikoloho: Sephutheloana se lokela ho koaloa 'me se lokela ho bolokoa ka thoko ho li-oxidant le li-acid.
Ho sebetsana le tsona: Laela le ho laolla lintho butle ha o ntse o di tsamaisa ho thibela tshenyo ya sephutheloana le setshelo.
3. Litlhoko tsa lipalangoang:
Sehlopha sa kotsi: Diphenylamine ke ntho e kotsi 'me e lokela ho tsamaisoa e le ntho e kotsi.
Maemo a lipalangoang: Qoba mocheso o phahameng, malakabe a bulehileng le motlakase o sa sisinyeheng, etsa bonnete ba hore setshelo se koetsoe hantle ho thibela ho dutla.
Mehato ea tšohanyetso: Hlomella ka lisebelisoa tse loketseng tsa ho tima mollo, tse kang carbon dioxide, foam, phofo e omileng, jj. Qoba ho fafatsa ka metsi ka kotloloho ho thibela ho bela le ho fafatsa.
Haeba ho ka ba le mollo, tima ka metsi, lehlabathe le setima-mollo!
