“Kwanduza Varnish ni ikibazo gikunze kugaragara mu mavuta menshi ya gaz turbine.Ubu bwoko bwanduye bufite imiterere ya polar?Impapuro nyinshi ziraboneka zivuga kwanduza langi, ibitera n'umuti.Mubyinshi muri izi mpapuro, imitungo ya polar yibintu bya langi yemeye nkukuri kugaragara, ariko ubushakashatsi nubushakashatsi ntabwo tubishyigikira.Uratekereza iki kuri iki kibazo?
Muri rusange, varish izwiho kuba igizwe na polar.Ariko, irashobora kandi kubamo ibidafite inkingi.Varnish ntabwo byoroshye kubisobanura kuko nta bwoko bumwe.Ibintu byinshi bigira ingaruka kumiterere ya varish ikora, harimo imikorere, ubwoko bwamavuta nibidukikije.
Aho kugerageza gushyira ibipimo byihariye kumiterere ya varish, hepfo nurutonde rwibintu 10 bigomba kumvikana kuri varish kuko ikoreshwa kumavuta.
1. Imiterere ya Varnish irashobora gutangirira kuri okiside na polymerisiyasi yamavuta nandi mazi yose cyangwa umuvuduko ukabije wumuriro hamwe na mazutu.Igishushanyo gikurikira kirerekana uburyo bwibanze bwo gushinga amarangi.Nubwo hariho izindi mpamvu nyinshi zitera langi, izi nizo zigaragara cyane.
2. Varnish mubusanzwe ni subicron mubunini kandi ahanini igizwe na oxyde oxyde cyangwa ibintu bya karubone.Ibiyigize birashobora gukomoka kubintu bya thermo-okiside ya molekile ya peteroli yibanze hamwe ninyongeramusaruro kimwe no kwambara ibyuma nibihumanya nkumwanda nubushuhe.Inzibacyuho ihindagurika hagati yo gushyushya no gukonjesha byerekana amavuta kwangirika kwubushyuhe na okiside.
3. Ihinduka rya larnish na silige biva mu mvura ya molekile-ifite uburemere buke bwa okiside idashobora kuva mu mavuta.Nkibintu byingenzi bya polar, iyi oxyde ifite ubushobozi buke bwo gukama mumavuta yibanze ya polar nkamavuta ya turbine.
4. Ibi birema firime yoroheje, idashobora gushonga itwikiriye imbere yimbere yibice byimashini kandi igatera gukomera no gukora nabi ibice byimuka byegeranye nka servo-valve.
5. Kugaragara kwa varish kumashini yimbere irashobora guhinduka kuva ibara ryijimye ukajya mubintu byijimye byijimye.
6. Varnish irashobora kandi guterwa no guhumeka ikirere cyatewe no kwikuramo adiabatic mukarere karimo imizigo.Ibibyuka byo mu kirere bifunikwa vuba, biganisha ku kubora kwamavuta hamwe ninyongeramusaruro.
7. Mugihe cyambere cya okiside no gushiraho okiside byongera umusaruro, ububiko bwibanze bwa Groupe II burarwanya cyane.Nyamara, nkuko byinshi bya okiside byongera umusaruro, ibyo bigega byibanze birashobora kwibasirwa nibibazo bya langi bitewe nurwego rwinshi rwa polarite.
8. Imiterere yimikorere nka zone yumuvuduko ukabije utandukanye, igihe kirekire cyo gutura hamwe nuwanduye nkamazi birashobora guteza okiside.
9. Usibye umwijima w'amavuta, ubushobozi bwa varish burashobora gukurikiranwa muburyo bwo kumenya ibisigisigi byose, igitereko cyangwa gummy ibintu bisa mubirahure byo kureba, imashini yimbere, ibintu byo kuyungurura hamwe no gutandukanya centrifugal.
10. Ubushobozi bwa Varnish burashobora kandi gukurikiranwa hifashishijwe isesengura ryamavuta ukoresheje Fourier transform infrared (FTIR) spectroscopy, ultracentrifuge, isesengura ryamabara, isesengura rya gravimetric hamwe na membrane patch colorimetry (MPC).
