“Ungcoliseko lwevarnish yingxaki eqhelekileyo kwiioli ezininzi ze-injini yegesi.Ngaba olu hlobo longcoliseko luneempawu zepolar?Kukho amaphepha amaninzi akhoyo axoxa ngongcoliseko lwevarnish, izizathu zalo kunye nonyango.Kuninzi lwala maphepha, iimpawu ze-polar zomxholo we-varnish zamkelwe njengenyaniso eqinisekisiweyo, kodwa uphando lwethu kunye novavanyo aluxhasi oku.Luthini uluvo lwakho ngalo mba?
Ngokuqhelekileyo, i-varnish iyaziwa ukuba iqukethe iipropati ze-polar.Nangona kunjalo, inokuqulatha izinto ezingezizo iipolar.I-Varnish akulula ukuyichaza kuba akukho didi olulodwa.Izinto ezininzi zichaphazela uhlobo lwe-varnish eyenza, kubandakanywa iimeko zokusebenza, uhlobo lweoli kunye nokusingqongileyo.
Kunokuba uzame ukubeka iiparitha ezithile kwiipropati ze-varnish, ngezantsi kukho uluhlu lwezinto ezili-10 ezimele ziqondwe malunga ne-varnish njengoko isebenza kwi-lubrication.
1. Ukwakhiwa kwe-Varnish kunokuqala kwi-oxidation kunye ne-polymerization ye-lubricants kunye nolunye ulwelo okanye ukuchithwa kwe-thermal kunye ne-diesling.Umfanekiso ongezantsi ubonisa iindlela eziphambili zokwenza i-varnish.Nangona zininzi ezinye izizathu zevanishi, ezi zezona ziphawulekayo.
2. Ivarnish ngokuqhelekileyo i-submicron ngobukhulu kwaye ngokuyinhloko iqulethe i-adherent oxide okanye i-carbonaceous material.Amalungu ayo anokuthathwa kwi-thermo-oxidative compounds yeemolekyuli ze-oyile ezisisiseko kunye nezongezo kunye nokunxiba isinyithi kunye nezinto ezingcolisayo njengobumdaka kunye nokufuma.Utshintsho olujikelezayo phakathi kokufudumeza kunye nokupholisa lubeka i-oyile ekuthotyweni kwe-thermal kunye ne-oxidation.
3. Ukuqulunqwa kwe-varnish kunye ne-sludge kuphumela kwimvula ye-high-molecular-weight-insoluble oxides kwioli.Njengezinto eziphambili zepolar, ezi oxides zinokunyibilika okulinganiselweyo kwisiseko se-oyile engeyiyo i-polar njengeoyile ye-turbine.
4. Oku kudala ifilimu encinci, enganyibilikiyo egquma iindawo zangaphakathi zamacandelo omatshini kwaye ibangele ukunamathela kunye nokungasebenzi kakuhle kwamacandelo ahambayo okucoca njenge-servo-valve.
5. Ukubonakala kwevanishi kumacandelo omatshini angaphakathi kunokutshintsha ukusuka kumbala we-tan ukuya kwizinto ezimnyama ezifana ne-lacquer.
6. I-Varnish nayo inokubangelwa ngamaqamza omoya afakwe kwi-adiabatic compression kwiindawo zomthwalo.La maqamza omoya anyanzeliswa ngokukhawuleza, okukhokelela ekuboleni kweoli kunye nezongezo.
7. Ngexesha lezigaba zokuqala ze-oxidation kunye nokubunjwa kwe-oxidation byproducts, i-Group II isiseko sesiseko sixhathisa.Nangona kunjalo, njengoko uninzi lweeproducts ze-oxidation zenza, ezi zitokhwe zisisiseko zinokuchaphazeleka ngakumbi kwimiba yevarnish ngenxa yenqanaba labo eliphezulu le-polarity.
8. Iimeko zokusebenza ezifana nemimandla ehlukanisiweyo yoxinzelelo oluphezulu, amaxesha okuhlala ixesha elide kunye nokungcola okufana namanzi kunokukhuthaza i-oxidation.
9. Ukongeza kubumnyama beoli, amandla e-varnish anokujongwa ngokujonga nayiphi na intsalela, i-tar okanye i-gummy-efana ne-gummy-efana ne-glass glasses, indawo yangaphakathi yomatshini, izinto zokucoca kunye ne-centrifugal separators.
10. Amandla evarnish nawo anokujongwa ngohlalutyo lwe-oyile kusetyenziswa i-Fourier transform infrared (FTIR) spectroscopy, i-ultracentrifuge, uhlalutyo lombala, uhlalutyo lwegravimetric kunye ne-membrane patch colorimetry (MPC).
