Kwimisebenzi yemizi-mveliso, ukukhethwa kwezinto zokupakisha iivalvu zezixhobo kubalulekile ukuqinisekisa ukusebenza kakuhle kunye nobomi benkonzo. Phakathi kweendlela ezahlukeneyo ezikhoyo, izizalisi zegrafiti zibonakala ngeempawu zazo ezikhethekileyo kunye neenzuzo ezininzi. Eli nqaku liphonononga iingenelo zokupakisha igrafiti ngokukodwa kwiivalvu zezixhobo, ligxininisa ukuba kutheni lukhetho lokuqala kumashishini amaninzi.
IHikelok inokubonelela ngeendlela ezahlukeneyoiivalvu zezixhoboukuba kunye nokupakisha igrafiti, njengeIivalvu zeBhola,Iifolda ezininzi,Iivalvu Zenaliti,Ivalvu yokulinganisa, Ivalvu yeBhloko kunye neCopednjl. njl.
Ukumelana nobushushu obuhle kakhulu
Enye yezona nzuzo zibalulekileyo ze-graphite filler kukumelana kwayo nobushushu obuphezulu. I-Graphite inokumelana nobushushu obugqithisileyo, kwezinye iimeko, ukusuka kumaqondo obushushu angabonakaliyo ukuya kuma-500°C (932°F). Oku kuyenza ifaneleke kwiivalvu zezixhobo ezisebenza kwiindawo ezinobushushu obuphezulu ezifana neoyile negesi, ukucubungula iikhemikhali kunye nokuvelisa umbane. Ukukwazi ukugcina ukuthembeka phantsi kweemeko ezinjalo kuqinisekisa ukuba ivalvu isebenza ngokufanelekileyo ngaphandle komngcipheko wokuvuza okanye ukungaphumeleli.
Ukuhambelana kakuhle kweekhemikhali
Iivalvu zezixhobo zihlala ziphatha iintlobo ngeentlobo zolwelo, kuquka iikhemikhali ezirhabaxa kunye neendawo ezirhabaxa. Izizalisi zegrafiti zinika ukumelana okukhulu kweekhemikhali, nto leyo ezenza zifaneleke ukusetyenziswa kwiindawo apho izizalisi zemveli zinokonakala okanye zingasebenzi. Uhlobo lwayo lokungangeni luyivumela ukuba imelane nokuchatshazelwa zii-asidi, iziseko kunye nezinyibilikisi, ukuqinisekisa ukuba ukupakisha kuhlala kuqinile kwaye kusebenza ngokuhamba kwexesha. Oku kuhambelana kweekhemikhali akupheleli nje ekwandiseni ubomi bokupakisha, kodwa kunciphisa neendleko zokulungisa ezinxulumene nokutshintshwa rhoqo.
Ukungqubana okuphantsi kunye nokuguguleka
Enye inzuzo yezizalisi zegrafiti kukuba zineempawu zokungqubana eziphantsi. Xa zisetyenziswa kwiivalvu zezixhobo, ukupakisha igrafiti kunciphisa ukuguguleka kwiziqu zeevalvu kunye nezinye izinto, nto leyo ebangela ukusebenza kakuhle kunye nokusetyenziswa kwamandla okuncitshisiweyo. Olu phawu luluncedo ngakumbi kwizicelo apho iivalvu zijikeleza rhoqo okanye ziphantsi koxinzelelo oluphezulu. Ukunciphisa ukungqubana kukwanceda ekunciphiseni ukuveliswa kobushushu, nto leyo ephucula ngakumbi ukusebenza kakuhle kwenkqubo.
Iipropati zokuzithambisa ngokwazo
I-Graphite sisithambisi sendalo, oko kuthetha ukuba inika iipropati zokuzithambisa xa isetyenziswa njengesizalisi. Olu phawu luluncedo kakhulu kwiivalvu zezixhobo kuba lunceda ekunciphiseni isidingo se-lubricant eyongezelelweyo, enokuthi ngamanye amaxesha iphazamise ukusebenza kwevalvu okanye ingcolise i-media ecutshungulwayo. Iipropati zokuzithambisa zokupakisha i-graphite ziqinisekisa ukusebenza kakuhle kwevalvu naphantsi kweemeko ezinzima.
Ukuguquguquka kunye nokwenza ngokwezifiso
Izizalisi zegrafiti zinokuguquguquka kwaye zinokwenziwa ngokwezifiso ukuze zihlangabezane neemfuno ezithile zokusetyenziswa. Zingenziwa ngeendlela ezahlukeneyo, kubandakanya imilo ephothiweyo, ebunjiweyo okanye ekhutshiweyo, zibonelela ngezisombululo ezenzelwe iintlobo ezahlukeneyo zeevalvu zezixhobo. Oku kuguquguquka kwenza izizalisi zegrafiti zifaneleke ukusetyenziswa kumashishini ahlukeneyo, ukusuka kumayeza ukuya kwiikhemikhali zepetroli, ukuqinisekisa ukuba zinokuhlangabezana neemfuno ezizodwa zokusetyenziswa ngakunye.
Ukusebenza kakuhle kweendleko
Nangona ixabiso lokuqala le-graphite fillers linokuba phezulu kunezinye ze-fillers zemveli, iingenelo zexesha elide zihlala zingaphezulu kotyalo-mali oluza kuqala. Ukuqina kwe-graphite filler, iimfuno eziphantsi zokugcinwa kunye nobomi benkonzo ende kunegalelo ekongeni iindleko ezinkulu ngokuhamba kwexesha. Ngokunciphisa ukuphindaphinda kokutshintshwa kunye nokunciphisa ixesha lokungasebenzi, iinkampani zinokufumana isisombululo esingabizi kakhulu kwiivalvu zazo zezixhobo.
Cisiphelo
Ngamafutshane, iingenelo zokupakisha igrafiti kwiivalvu zezixhobo zininzi kwaye ziyathandeka. Ukumelana kwayo nobushushu obuphezulu, ukuhambelana kwayo okugqwesileyo kweekhemikhali, ukungqubana okuphantsi, iipropati zokuzithambisa, ukuguquguquka kunye nokusebenza kakuhle kweendleko kwenza ukuba ilungele ukusetyenziswa kwezixhobo ezahlukeneyo. Njengoko ishishini liqhubeka nokukhula kwaye lifuna izisombululo ezithembekileyo nezisebenzayo, ukupakisha igrafiti ngokuqinisekileyo kuya kuhlala kukhetho lokuqala ukuqinisekisa ukusebenza kakuhle kweevalvu zezixhobo.
