Codsiga cusub ee tignoolajiyada ka saarista varnish ee matooriyaha marawaxadaha gaaska sola

3.1 sababta kor u kaca heerkulka baadiyaha

3.1.1 Saliidda saliidda ee loo isticmaalo cutubkan waa CASTROL PERFECTO X32, oo ah saliidda macdanta.Marka heerkulku sarreeyo, saliidda saliidayntu way fududahay in la oksijiinta, iyo alaabooyinka oksaydhisku waxay ku ururaan dusha sare ee geed si ay u sameeyaan varnish.Marka la ogaado index of saliid socda unit, waxaa la ogaaday in index u janjeera varnish waa sare, iyo heerka wasakhda sidoo kale waa sare (eeg Shaxda 5).Tusmada u janjeera ee varnish waa sare, taas oo laga yaabaa in ay sabab u formation of lifaaqa iyo raasamaal on baadiyaha sita, sidaas yaraynaysaa farqiga u filimka saliidda, khilaaf sii kordhaya, iyo taasoo keentay in kulaylka liidata ee baadiyaha sita, kor u kaca ee axial. heerkulka iyo dardargelinta oksaydhka saliidda.Isla mar ahaantaana, wasakhowga sare leh ee saliidda awgeed, varnishku wuxuu u hoggaansami doonaa walxaha kale ee wasakhaysan, samaynta saamaynta shiida iyo sii xumeynta xirashada qalabka.

Si loo falanqeeyo sababta keentay kor u kaca heerkulka baadiyaha xanbaarsan, waxaa laga yaabaa in faashad laga soo saaro saliidda saliidda ee cutubka, iyo varnish ugu dambeyntii wuxuu diiradda saarayaa baadiyaha sidda, taasoo keentay isbeddelka heerkulka iyo kor u kaca baadiyaha sidda.

3.1.2Sababaha varnish

* Saliidda macdantu waxay inta badan ka kooban tahay hydrocarbons, kuwaas oo aad u deggan heerkulka qolka iyo heerkulka hooseeya.Laakiin haddii ay dhacdo heerkulka sare, qaar (xitaa haddii tiradu aad u yar tahay) molecules hydrocarbon waxay mari doonaan falcelinta oksaydhka, molecules kale ee hydrocarbon waxay sidoo kale raaci doonaan falcelinta silsiladda, taas oo ah dabeecadda falcelinta silsiladda hydrocarbon;

* Saliiddu waxay samaysaa varnish milmi leh heerkulka sare iyo aagga cadaadiska sare.Nidaamka socodka saliidda ee ka soo baxa heerkulka sare ee heerkulka hooseeya, hoos u dhaca heerkulka ayaa keenaya hoos u dhaca milanka, iyo qaybaha varnish ayaa ka soo qulqulaya saliidda saliidda waxayna bilaabaan inay kaydiyaan;

* Dhigista varnish ayaa dhacda.Ka dib markii la sameeyo qaybo ka mid ah varnish, saddaxdu waxay bilaabataa inay isku ururiso oo ay samaysato wasakhda ayaa si gaar ah loogu dhejin doonaa dusha sare ee birta kulul, taasoo keentay in heerkulka baadiyaha uu si dhakhso ah u kaco heerkulka saliidda sidoo kale si tartiib tartiib ah ayuu u kici doonaa;

* Isbeddelka heerkulka oo ay sababi karaan arrimo kale oo deegaanka ah ama dhibaatooyinka cilladda ee unugga.

3.2 Tallaabooyinka lagu xallinayo dhibaatada kororka heerkulka baadiyaha sidda

3.2.1 Kor u qaad cadaadiska saliidda saliidda laga bilaabo 0.23 Mpa ilaa 0.245 Mpa si loo hagaajiyo waxtarka wareejinta kulaylka saliidda oo loo yareeyo isbeddelka tartiib tartiib ah ee kor u kaca heerkulka baadiyaha.

3.2.2 Ku beddel qaboojiyaha saliidda simbiriiraxa leh hufnaanta wareejinta kulaylka gabowga hoose leh qaboojiye toos ah oo gudaha ah oo cusub, iyo heerkulka sahayda saliidda simbiriirixan waa mid deggan laga bilaabo 60 ℃ ilaa 50 ℃ muddo dheer.

3.2.3 Mabda'a shaqada ee tignoolajiyada adsorption electrostatic -- ka saarida varnish degdega ah (eeg sawirka 4)

Nadiifinta Electrostatic waa isticmaalka wareeg ah oo danab static field, ka dhigi qayb wasakhda saliidda muujiyaan koronto togan iyo taban siday u kala horreeyaan, qayb koronto togan iyo taban hoos ficil jihada electrode taban iyo togan, qayb dhexdhexaad ah tuujiyey by socodka walxaha la soo oogay, ugu dambeyntii dhammaan qaybaha adsorption on ururiyaha, gebi ahaanba ka saar wasakh ah ee saliidda, la socodka qaybaha saliidda electrostatic, taangiga, derbiga tuubada iyo qaybaha dhoobada oo dhan wasakhda, adsorption oxide baxay, firfircoon ka saar nidaamka dusha dhoobo koolo iyo wasakh , ciyaara doorka nidaamka nadiifinta.

Jaantus 4. Sharaxaada qaabaysan ee tignoolajiyada adsorption electrostatic

3.2.4 Mabda'a shaqada ee tignoolajiyada adsorption resin-ion —— Ka saar faashka milmay

DICR resin ion beddelashada DICR ™ waxay ka saari kartaa wasakhda milmaya ee saliidda marawaxadaha, iyada oo hubinaysa hoos u dhaca tilmaamayaasha MPC, sababtoo ah inta badan marawaxadaha waa milmi inta lagu jiro hawlgalka, oo kaliya alaabooyinkani waxay samayn doonaan roobab, qalabka korantada kama saari karo kuwan alaabooyinka gudaha gobolka lakala diray.

Isku-darka xayeysiinta korantada iyo tignoolajiyada resin ma aha oo kaliya inay si wax ku ool ah uga saaraan varnish-ka la hakiyay, laakiin sidoo kale waxay ka saaraan alaabta varnish ee kala diri.

3.3 Saamaynta ka saarista faashka

Diseembar 14,2019, shaandhada saliidda WVD model varnish waa la rakibay oo la shaqeeyay.Iyada oo la raacayo cabbirka guud ee lagu beddelayo qaboojiyaha marawaxadaha gaaska Agoosto 20,2020, heerkulka marawaxadaha ( baadiyaha) ayaa hoos uga dhacay 108 ℃ ilaa 90℃Midabka saliidda ayaa si weyn loo hagaajiyay (Jaantuska 7 isbarbardhigga saliidda ka hor iyo ka dib nadiifinta).Iyada oo loo marayo falanqaynta iyo xogta tijaabada dibadda, tusaha u janjeera saliidda saliidda ayaa laga dhimay 42.4 ilaa 4.5, heerka wasakhda ayaa laga dhimay NAS 9 ilaa 6, iyo tusaha qiimaha aashitada ayaa laga dhimay 0.17 ilaa 0.07.
