Impembelelo yeeparamitha zenkqubo eyohlukileyo kwisiphumo sokuthotywa kodonga olungqingqwa lwentsimbi engenamthungo

Ngokohlalutyo lwemodeli yemathematika, itheyibhile yovavanyo yedatha yenkqubo yokungcangcazela iiparamitha zenkqubo etyebileyo enodonga lwentsimbi engenamthungo isekiwe.Uvavanyo lwesiphumo sokungcangcazela luye lwaqhutywa kwiindlela ezahlukeneyo zokungcangcazela kwiiparamitha zenkqubo ezichaphazela impembelelo yokungcangcazela kwetyhubhu etyebileyo engenamthungo yentsimbi engenamthungo, kunye nokuhlolwa kothelekiso lwe-macroscopic kunye ne-metallographic yesiphumo sokudiliza lwenziwa.Isiphumo seeparamitha zenkqubo ezahlukeneyo kwisiphumo sokuthotywa kwetyhubhu etyebileyo enentsimbi engenamthungo yahlalutywa kwaye yavavanywa.(1) i-abrasive hardness ye-rust intlangano ikhululekile, kodwa umaleko we-oxide kumphezulu wesinyithi kunye nesiseko sezinto ezidibanisa amandla aphezulu, ukuphakama kwamasuntswana ubulukhuni, isiphumo esingcono sokususa i-rust kunye ne-oxide layer Kuba amasuntswana ezinto ezifanayo. , ubungakanani bukhulu, kwaye indawo yoqhagamshelwano phakathi kweengqungquthela kunye nebala lokugqwala liyanda, elichaphazela uxinzelelo lwempembelelo.Ngobungakanani bombhobho wensimbi kulolu vavanyo, ububanzi beengqungquthela, D> 1.1-1.5 mm, ngokusisiseko akukho mpembelelo yokususa i-rust.D > 0.9 ~ 1.1 mm, i-derusting ibonakala, D <0.9 mm, i-particle mass incinci, amandla e-kinetic amancinci, i-derusting effect impofu;(4) Ubudlelwane phakathi kwe-amplitude kunye ne-frequency acceleration, i-amplitude kunye ne-frequency yimi ngolu hlobo lulandelayo: i-amplitude enkulu, i-acceleration enkulu, inkulu i-particle kinetic energy, ingcono i-derusting effect;Ngokunyuka kokuphindaphinda, ukunyuka kwesantya kunyuka, kodwa i-amplitude iyancipha, isiphumo sokunciphisa siyancipha, izinga lokuphindaphinda liphantsi kakhulu, kwaye ukusebenza kakuhle kuphantsi.Xa sithetha ngokubanzi, okukhona ixesha lisiba lide, kokukhona kucaca ngakumbi isiphumo sokuthomalalisa.(6) Isalathiso sokungcangcazela kukungcangcazela okuthe nkqo, kwaye amandla empembelelo yamasuntswana abrasive kumphezulu asetyenziselwa ukususa amabala omhlwa kunye nesikali seoksidi, okukhokelela kuxinzelelo olushiyekileyo olucinezelayo kumphezulu, ukucokisa iinkozo zomphezulu, ezinokuphucula ukumelana nomhlwa. ;Ukungcangcazela okuthe tyaba kusebenzisa ukukhuhlana ukususa amabala omhlwa kunye nolusu oluyioksidi, okukhokelela kuxinzelelo olushiyekileyo oluphezu komhlaba, olungasebenziyo kangako kunongcangcazelo oluthe nkqo.Ukungcangcazela okudityanisiweyo kunokuphucula ukusebenza kakuhle kokunciphisa kunye nokulinganisa, kwaye kuvelise intsalela yoxinzelelo loxinzelelo kumphezulu.
