"Varnish kusvibiswa idambudziko rinowanzoitika mumafuta akawanda egasi.Ko rudzi urwu rwekusvibiswa rune polar properties?Mapepa akawanda aripo achikurukura nezvekusvibiswa kwevarnish, zvikonzero zvayo uye mishonga.Mune mazhinji emapepa aya, iyo polar zvimiro zvevarnish zvakagamuchirwa sechokwadi chakasimbiswa, asi tsvakiridzo yedu uye zviedzo hazvitsigire izvi.Ndeapi maonero ako panyaya iyi?
Kazhinji, varnish inozivikanwa kuti inosanganisira polar properties.Nekudaro, inogona zvakare kuve neasiri-polar anomiririra.Varnish haisi nyore kutsanangura nekuti hapana mhando imwechete.Zvinhu zvakawanda zvinokanganisa rudzi rwevarnish inoumba, kusanganisira mamiriro ekushanda, rudzi rwemafuta uye zvakatipoteredza.
Panzvimbo pekuedza kuisa maparamendi chaiwo pazvivakwa zvevarnish, pazasi pane runyorwa rwezvinhu gumi zvinofanirwa kunzwisiswa nezvevarnish sezvazvinoshanda pakuzora.
1. Varnish formation inogona kutanga kubva kune oxidation uye polymerization yemafuta emafuta uye mamwe mvura kana kudzvinyirira-induced thermal degradation uye diesling.Mufananidzo uri pasi apa unoratidza nzira dzekutanga dzekugadzira varnish.Kunyange zvazvo kune zvimwe zvikonzero zvakawanda zvevarnish, izvi ndizvo zvinonyanya kukosha.
2. Varnish inowanzoita submicron muhukuru uye inonyanya kuumbwa neadherent oxide kana carbonaceous material.Mamiriro ayo anogona kutorwa kubva kune thermo-oxidative makomisheni eiyo base oiri mamorekuru uye ekuwedzera pamwe nekupfeka simbi uye zvinosvibisa zvakaita setsvina nehunyoro.Cyclical shanduko pakati pekudziya nekutonhodza inofumura oiri mukuderera kwekupisa uye oxidation.
3. Kuumbwa kwevarnish uye sludge kunobva pakunaya kwepamusoro-molecular-weight insoluble oxides kubva mumafuta.Sezvinonyanya zvinhu zvepolar, maokisi aya ane kushomeka kunyungudika mumafuta asiri-polar base semafuta eturbine.
4. Izvi zvinogadzira firimu rakatetepa, risinganyunguriki rinoputira mukati mezvikamu zvemichina uye rinokonzera kunamatira uye kusashanda kwezvikamu zvekuvhara-pedyo zvinofamba sevhavhavha.
5. Kuonekwa kwevarnish pamichina yemukati zvikamu zvinogona kuchinja kubva kune tan ruvara kusvika kune yakasviba lacquer-yakafanana zvinhu.
6. Varnish inogonawo kukonzerwa ne-entrained air bubbles inosangana neadiabatic compression munzvimbo dzekutakura.Aya mabhuru emhepo anomanikidzwa nekukurumidza, zvichitungamira mukuwora kwemafuta uye zvinowedzera.
7. Pakati pezvikamu zvekutanga zve oxidation uye kuumbwa kwe oxidation byproducts, Group II base base stocks inowedzera kusagadzikana.Nekudaro, sezvo yakawanda oxidation byproducts inoumba, aya mashesi emasheya anogona kuve nyore kubatwa nevanish nyaya nekuda kweyepamusoro nhanho yepolar.
8. Mamiriro ekushanda akadai seakakwirira-kudzvinyirira kusiyanisa nzvimbo, nguva dzekugara kwenguva refu uye zvinosvibisa semvura zvinogona kukurudzira oxidation.
9. Mukuwedzera kune kusviba kwemafuta, simba revarnish rinogona kutariswa nekuona chero zvakasara, tar kana gummy-yakafanana nezvinhu zvinotarisa magirazi, mukati memuchina wepamusoro, sefa zvinhu uye centrifugal separators.
10. Varnish inogona zvakare kutariswa kuburikidza neoiri kuongororwa uchishandisa Fourier transform infrared (FTIR) spectroscopy, an ultracentrifuge, colorimetric analysis, gravimetric analysis uye membrane patch colorimetry (MPC).
