Ukuthwala insimbi yensimbi yokusika amatshe ngempilo ende
Incazelo Yomkhiqizo
I-Bearing steel grit yenziwe nge-chrome alloy material eyenza i-athomu ngokushesha ngemva kokuncibilika. Ngemuva kokwelashwa okushisa, kuvezwa ngezici ezinhle zemishini, ukuqina okuhle, ukumelana nokukhathala okuphezulu, impilo ende yokusebenza, ukusetshenziswa okuphansi nokunye. U-30% uzosindiswa. Isetshenziswa kakhulu ekusikeni kwegwadle, ukuqhumisa isihlabathi kanye nokuchama.
I-Bearing steel grit yenziwe nge-iron carbon alloy steel, esetshenziselwa ukwenza amabhola, ama-roller namasongo okuzala. Insimbi enensimbi inokuqina okuphezulu nokufana kanye nezikhathi zokujikeleza okuphezulu, kanye nokunwebeka okuphezulu. Ukufana kokwakheka kwamakhemikhali, okuqukethwe kanye nokusatshalaliswa kwe-non-metallic inclusions kanye nokusatshalaliswa kwe-carbides yensimbi ethwalayo kuqinile kakhulu, okungenye yezidingo eziphakeme kukho konke ukukhiqizwa kwensimbi.
Insimbi enegridi iqukethe insimbi eyigugu - i-chromium, ngenqubo yokukhiqiza eyingqayizivele, isakhiwo esihle kakhulu se-metallographic, izinhlayiya zomkhiqizo ogcwele, ubulukhuni obufanayo, izikhathi zomjikelezo ophezulu, zingathuthukisa ngempumelelo izinga lokutakula (ukuqubuka kwenqubo yokuqhunyiswa kwesihlabathi kuncishiswe kancane kancane), ukuze ukunciphisa ukusetshenziswa kwe-abrasive kufike ku-30%.
Inkambu yohlelo lokusebenza
Ukuthwala insimbi yensimbi yokuqhuma kwesihlabathi
Ukuthwala ikhwalithi yegrit yensimbi esetshenziselwa ingxenye yomzimba yokuqhunyiswa kwesihlabathi kuthinta ngokuqondile ikhwalithi kanye nesici sezindleko esiphelele ngokuya ngokusebenza kahle kokuqhunyiswa kwesihlabathi, ukumbozwa kwebhande, ukudweba, amandla e-kinetic kanye nokusetshenziswa kwe-abrasive. Ngokukhishwa okusha kwe-coating protection performances standard (PSPC), kunesicelo esiphezulu sekhwalithi yokuqhunyiswa kwesihlabathi esihlakaniphile. Ngakho-ke, ikhwalithi ye-Steel grit ibaluleke kakhulu ekuqhumeni kwesihlabathi.
Ama-angular granules wesitsha se-sandblasting
Ama-angular granules aqhuma esihlabathini sebhokisi lesiqukathi ngemva kokushisela. Hlanza ijoyinti elishiselwe futhi ngasikhathi sinye ubangele ukuthi indawo yomzimba webhokisi ibe nobulukhuni obuthile futhi yandise umphumela wokupenda wokubola, ukuze ukwazi ukusebenza isikhathi eside phakathi kwemikhumbi, i-chassis, imoto yezimpahla kanye izimoto zikaloliwe.
Insimbi eyi-angular grit ye-Sandblasting yezinto zikagesi wasensimini.
Umkhiqizo kagesi wasensimini unesicelo esiqondile sokulukhuni nokuhlanzeka kokwelashwa kwendawo. Ngemuva kokwelashwa kwe-angular steel grit surface, kufanele babhekane nezinhlobo zezinguquko zesimo sezulu ngaphandle isikhathi eside. Ngakho-ke, ukuqhuma kwesihlabathi se-angular grit for surface kubaluleke kakhulu.
Igridi yensimbi yokusika kanye negrit yokusika yamatshe
Ukusika itshe ngokusebenzisa igridi yensimbi yokusika kanye negrit yokusika yamatshe ekugelezeni kwejethi yamanzi. Ngesikhathi sokusika, i-grit ye-sawing grit ayinakho ukuguqulwa kwamakhemikhali futhi inezinzuzo zokungathandi amakhemikhali nokusebenza komzimba wezinto zamatshe, akukho ukuguquguquka kokushisa, i-lancing ewumngcingo, ukunemba okuphezulu, indawo yokusika ebushelelezi, ukuhlanzeka futhi akukho ukungcola, njll.
Igrit eyi-angular yensimbi ye-Locomotives yokuqhuma kwesihlabathi
Ngemva kokuphothula ukwakhiwa noma ukuguquguquka, indawo yesitimela kufanele ipendwe (kuhlanganise nejazi elingaphansi, ijazi eliphakathi nendawo, i- finishing coating nokunye), ukuze kuthuthukiswe ukubukeka kwangaphandle kwesitimela kanye nempilo yokusebenza. Ukukhethwa kwensimbi eyi-angular Grit kubaluleke kakhulu ekwelapheni okungaphezulu, okuthinta ukusebenza kwe-coating ye-anti-crack, ukumelana nokungena kanye ne-inoxidizability.
I-angular steel grit yesakhiwo sensimbi
Esakhiweni sensimbi, isivinini sokugqwala sihlobene kakhulu nokuswakama komoya okuhlobene kanye nokwakheka kanye nenani lokungcolisa umoya emkhathini. Ukuze kunwetshwe impilo yaso yesevisi, isakhiwo sensimbi kufanele sidinge ukwelashwa kwe-Angular steel grit blasting surface, bese ngokufafaza ukwenza ifilimu yokuvikela endaweni yensimbi ukuvimbela nokunciphisa ukugqwala kwensimbi.
I-Steel Grit Manufacturer yePort Machinery sandblasting
Ukwakhiwa kwechweba lechweba kusebenzisa isakhiwo sensimbi kakhulu. Ngakho-ke, isicelo se-steel anti-corrosion siphezulu kakhulu. Imishini yasechwebeni ivamise ukubhekana nendawo ethile ekhethekile. Isibonelo, indawo yomoya yasolwandle eswakeme, edala ukuthi izakhiwo zensimbi zigxumeke ngokujulile. Kuleso simo, ukuqhunyiswa kwesihlabathi okuhambisanayo kanye nokunamathiswa kuyadingeka ukuze kuvikelwe imishini yechweba. Ngakho-ke ukwakhiwa okuhle kwegrit yensimbi kubaluleke kakhulu.
