"Isityalo sethu sicinga ngokutshintshela kwigrisi ye-lithium-complex kwigrisi ye-polyurea yokuthambisa amacandelo amaninzi omatshini wethu. Ngaba kukho naziphi na iingenelo okanye iingxaki zokusebenzisa igrisi ye-polyurea phezu kwegrisi ye-lithium-complex ukuba zonke ezinye izinto zilingana? "

Xa uthelekisa igrisi ye-polyurea kunye negrisi ye-lithium-complex, eyona nto inkulu kukuba i-polyurea thickeners ayihambelani.Oku kungahambelani kunokubangela ukuqina okanye ukuthamba kwegrisi.

Ukuthambisa igrisi kunokukhokelela kwimiba emininzi, njengokungavumeli ukuthambisa okufanelekileyo kweerola.Igrisi eyongezelelweyo kufuneka emva koko yongezwe ukugcina ukuthambisa okufanelekileyo de umxube ongahambelaniyo ususwe.

Ukuqina kwegrisi kunokukhokelela kwiingxaki ezimbi ngakumbi, njengoko igrisi ingasakwazi ukuhamba ingena kumngxuma wokuzala, ishiya ibherethi ilambile yokuthambisa.

Nangona kunjalo, i-polyurea thickeners ibonelela ngeenzuzo ezithile ngaphezulu kwe-lithium thickeners.Ngokomzekelo, iigrisi ze-polyurea zihlala zilolona khetho olukhethwayo kwizicelo ezitywiniweyo zobomi.Eziamafuthaidla ngokuba namaqondo obushushu aphezulu okusebenza, iipropathi zendalo ze-antioxidative, eziphezuluukuzinza kwe-thermalkunye neempawu zokopha okuphantsi.

Kananjalo banendawo yokuhla emalunga nama-270 degrees C (518 degrees F).Ukongeza, njengoko ukubunjwa kwabo kungasekelwanga kwizitshizi zesepha yesinyithi njengegrisi ze-lithium, ezinokushiya ngasemva intlenga emanzi xa isetyenzisiwe, ngokuqhelekileyo lolona khetho lukhethwayo lokuthanjiswa kwiinjini zombane.Ngokwe-avareji, igrisi ze-polyurea zinokuba nexesha eliphindwe kathathu ukuya kahlanu lobomi obungcono kune-lithium-based greases.

Kwelinye icala, i-lithium complex yeyona nto ixhaphakileyo kwimarike, yenza phantse i-60 pesenti yegrisi ekhoyo kuMntla Melika.Izibalo zokuhambelana zibonisa ukuba kukho uluhlu oluninzi lwee-thickeners apho i-lithium-complex thickeners ibonakalise ukuba iyahambelana.

Zikwalukhetho oluphambili lwe-thickener kubenzi bezixhobo ezininzi.Iigrisi zeLithium-complexngokubanzi zinika uzinzo oluhle, iimpawu zobushushu obuphezulu kunye neempawu ezithile zokumelana namanzi.

Zombini i-polyurea kunye ne-lithium-complex greases zineenzuzo kunye nokungalunganga kwazo, ngoko qiniseka ukuba uhlolisise ukuhambelana kunye ne-viscosity yemveliso nganye kuqala.

I-polyurea thickeners ingaba luncedo kwiindawo ezimanzi kunye nakwizicelo apho aubomi obude bamafuthakulindeleke.Uxinzelelo olugqithisileyo (EP)kunye nezongezo ze-antioxidant zinokudityaniswa ukunceda ukufezekisa ubomi obude kunye nokuthembeka kwezixhobo.

Ngokuqinisekileyo, ukusetyenziswa kunye neempawu ezifunwayo zegrisi ziya kuba nefuthe lokuba yeyiphi isiseko se-thickener ekufuneka isetyenziswe.
