Codsiyo badan oo mashiinada warshadaha, hagayaasha toosan ayaa ah qaybo lagama maarmaan ah oo bixiya siman, sax ahdhaqdhaqaaqa toosan.Saliid habboon ayaa door muhiim ah ka ciyaarta hubinta waxqabadka ugu wanaagsan iyo nolosha adeegga.Markaad dooranayso dufanka saxda ah ee hagaha toosan, waxaa muhiim ah in la tixgeliyo awoodda culeyska, xaaladaha hawlgalka iyo shuruudaha dayactirka.Maanta PYG waxay ku qaadan doontaa dufan kala duwan oo loogu talagalay hagayaasha tooska ah waxayna kaa caawin doontaa inaad doorato dufanka ugu fiican ee qalabkaaga.Noocyada dufan hagaha toosan:
1. Dufan lithium-ku-salaysan: Dufan-ku-salaysan lithium-ku-ku-salaysan waxa uu leeyahay awood-qaadis heersare ah, iska-caabbinta oksaydhka iyo heerkul ballaadhan oo ballaadhan, waana saliidda inta badan la isticmaalo ee hagayaasha toosan.Waxay bixiyaan sifeyn wanaagsan xitaa culeysyo culus iyo xawaare sare.

2. Dufanka synthetic: Dufanka la isku qurxiyo, sida polyurea ama dufanka fluorinat, waxay si fiican ugu habboon yihiin xaaladaha qallafsan ee shaqada halkaasoo heerkul aad u daran, culeysyo badan, ama wasakhdu ay jiraan.Dufanyadani waxay xoojiyeen xasilloonida kulaylka iyo iska caabbinta kiimikada, hubinta ilaalinta ugu badan iyo hawlgalka siman ee hagayaasha tooska ah.
3. Dufanka molybdenum disulfide (MoS2): Dufanka MoS2 waxa lagu yaqaanaa sifooyinkiisa ugu wanagsan ee ka-hortagga xidhashada waxana uu ku habboon yahay codsiyada leh heerar sare oo is jiid-jiid ah iyo xiriir simbiriirixan leh.Waxay ka samaysaa filim saliid leh oo xoog leh oo ku yaal dusha tareenka, yaraynta xirashada iyo kordhinta nolosha adeeggeeda.
4. PTFE (polytetrafluoroethylene) dufan: Dufan ku salaysan PTFE waxay bixisaa sifeyn aad u fiican iyo sifooyin hoose.Waxay si gaar ah faa'iido ugu leeyihiin codsiyada u baahan awoodaha is-saliimaynta, sida dhaqdhaqaaqa toosan ee xawaaraha sare leh ama marka la isticmaalayo hagitaan toosan oo la hagaajin karo.
Markaad dooranayso dufanka saxda ah ee hagahaaga toosan, tixgeli arrimaha soo socda:
- Awoodda culeyska iyo xaaladaha shaqada
- Heerkulka kala duwan (codsiyada heerkulka sare ama hooseeya)
- xawaaraha iyo inta jeer ee dhaqdhaqaaqa
- heerka wasaqowga deegaanka
- Inta u dhaxaysa saliidda iyo shuruudaha dayactirka
Dayactirka joogtada ah iyo sifaynta saxda ah ayaa ah qodobbada go'aaminta waxqabadka ugu wanaagsan ee hagayaasha tooska ah inta lagu jiro hawlgalka.Xaaladda dufanka si joogto ah ayaa loola socdaa oo la buuxiyaa ama la beddelaa haddii loo baahdo iyadoo loo eegayo talooyinka soo-saaraha.
Dayactirka joogtada ah ee hagayaasha tooska ah iyo u hogaansanaanta tilmaamaha soo saaraha ayaa kaa caawin doona hubinta shaqada hufan ee hagayaasha toosan, yaraynta wakhtiga hoos u dhaca iyo kordhinta wax soo saarka guud.Waxaan rajeynayaa in sharraxaadda PYG ay si wax ku ool ah kuu caawin karto, haddii aad weli shaki ka qabto, fadlannala soo xiriir, Adeegga macmiisha ee xirfada leh ayaa diyaar u ah inay ku caawiyaan.
