Umsebenzi onzima, Ikhwalithi Ephakeme GREASE
Gcobailubricant eqinile noma ene-semisolid eyakhiwe njengokuhlakazwa kwama-ejenti ajiya endaweni yokuthambisa ewuketshezi.Igrisi ngokuvamile iqukethe insipho emulsified ngamafutha amaminerali noma emifino.
Isici esivamile samafutha ukuthi ane-viscosity ephezulu yokuqala, okuthi lapho kusetshenziswa i-shear, ehle ukuze anikeze umphumela we-bearing egcotshwe ngamafutha ecishe ibe ne-viscosity efanayo nesisekelo samafutha asetshenziswa kugrisi.Lolu shintsho ku-viscosity lubizwa ngokuthi i-shear thinning.Igrisi kwesinye isikhathi isetshenziselwa ukuchaza izinto zokugcoba ezimane nje eziqinile ezithambile noma uketshezi olune-viscosity ephezulu, kodwa lezi zinsiza azibonisi izici zokuncipha kwe-shear zamafutha akudala.Isibonelo, ama-petroleum jellies afana noVaseline ngokuvamile awahlukaniswa njengamafutha.
Amafutha asetshenziswa ezindleleni ezingagcotshwa ngokungavamile nalapho uwoyela wokugcoba ungeke uhlale endaweni.Ziphinde zisebenze njengama-sealants ukuvimbela ukungena kwamanzi nezinto ezingenakucindezelwa.Ama-bearings agcotshwe ngamafutha anezici ezinkulu zokungqubuzana ngenxa ye-viscosity yawo ephezulu.
Aiqinisoamafutha aqukethe uwoyela kanye/noma okunye okokuthambisa okuwuketshezi okuxutshwe ne-thickener, ngokuvamileinsipho, ukwakha okuqinile noma i-semiolid.[1]Amafutha ngokuvamileukugunda ukugundanoma uketshezi-mbumbulu lwepulasitiki, okusho ukuthi i-viscosity yoketshezi iyancipha ngaphansi kwe-shear.Ngemuva kokuthi kusetshenziswe amandla anele okugunda amafutha, i-viscosity iyehla futhi isondele ku-lubricant eyisisekelo, njengamafutha amaminerali.Lokhu kwehla okungazelelwe kwamandla okugunda kusho ukuthi amafutha athathwa njengoketshezi lwepulasitiki, futhi ukuncishiswa kwamandla okugunda ngokuhamba kwesikhathi kwenza kube thixotropic.Amafutha ambalwa ane-rheotropic, okusho ukuthi aba ne-viscous kakhulu lapho esebenza.[2]Kuvame ukusetshenziswa kusetshenziswa isibhamu samafutha, esifaka amafutha engxenyeni egcotshwa ngaphansi kwengcindezi, iphoqelela igrisi eqinile ezindaweni eziyingxenye.
Okokugcina, kubalulekile ukuthenga amabhawodi kumnikezeli othembekile ukuze uqinisekise ukuthi imikhiqizo oyitholayo ingeyekhwalithi ephezulu kakhulu.
Sengiphetha, amabhawodi amasondo eloli aphezulu abalulekile kunoma ngubani osebenzisa iloli.Lawa mabhawodi aklanyelwe ukuphatha ingcindezi enkulu kanye nengcindezi, awenze alungele ukusetshenziswa ezindaweni ezimbi nemithwalo esindayo.Ngokukhetha usayizi ofanele, usebenzisa izinto zekhwalithi ephezulu, nokuthenga kumnikezeli ohloniphekile, ungaqinisekisa ukuphepha nokuphila isikhathi eside kwamasondo eloli lakho.Ngakho-ke uma kuziwa elolini lakho, ungayekethisi kwikhwalithi, tshala imali kumabhawodi amasondo eloli ekhwalithi ephezulu namuhla.
