Itshe eliyinsimbi elithwalayo lokusika amatshe elihlala isikhathi eside Isithombe Esifakiwe

Itshe eliqinile elithwala izinsimbi zokusika amatshe isikhathi eside

Incazelo emfushane:

I-grit yensimbi ethwalayo yenziwe ngezinto ze-chrome alloy ezishesha ukuncibilika ngemva kokuncibilika. Ngemva kokwelashwa ngokushisa, inezici ezinhle kakhulu zemishini, ukuqina okuhle, ukumelana nokukhathala okuphezulu, ukusebenza isikhathi eside, ukusetshenziswa okuphansi njalo njalo. Ama-30% azogcinwa. Isetshenziswa kakhulu ekusikeni i-granite, ukuqhumisa isihlabathi kanye nokuphuma kwesibhamu.

I-grit yensimbi ethwalayo yenziwe ngensimbi ye-carbon alloy yensimbi, esetshenziselwa ukwenza amabhola, ama-roller kanye namasongo okuthwala. Insimbi ethwalayo inobunzima obuphezulu nobufanayo kanye nezikhathi zokujikeleza eziphakeme, kanye nokuqina okuphezulu. Ukufana kokwakheka kwamakhemikhali, okuqukethwe kanye nokusatshalaliswa kwezinto ezingezona ezensimbi kanye nokusatshalaliswa kwama-carbide ensimbi ethwalayo kuqinile kakhulu, okungenye yezidingo eziphezulu kukho konke ukukhiqizwa kwensimbi.

I-grit yensimbi ethwalayo yenziwe ngezinto ze-chrome alloy ezishintshwa ngokushesha ngemva kokuncibilika. Ngemva kokwelashwa ngokushisa, inezici ezinhle kakhulu zemishini, ukuqina okuhle, ukumelana nokukhathala okuphezulu, ukusebenza isikhathi eside, ukusetshenziswa okuphansi njalo njalo. Ama-30% azogcinwa. Isetshenziswa kakhulu ekusikeni i-granite, ukuqhumisa isihlabathi kanye nokuphuma kwesibhamu.

I-grit yensimbi ethwalayo iqukethe insimbi eyigugu - i-chromium, ngenqubo yokukhiqiza ehlukile, isakhiwo esihle kakhulu se-metallographic, izinhlayiya zomkhiqizo ezigcwele, ubulukhuni obufanayo, izikhathi zomjikelezo ophezulu, ingathuthukisa ngempumelelo izinga lokutakula (ukuguguleka enkambisweni yokuqhuma kwesihlabathi kuncishiswe kancane kancane), ukuze kuncishiswe izinga lokusetshenziswa kokuguguleka kufika ku-30%.

Insimu Yesicelo

I-grit yensimbi ethwalayo yokuqhuma kwesihlabathi
Ikhwalithi yamatshe ensimbi athwalayo asetshenziselwa ingxenye yomzimba wokuqhumisa isihlabathi ithinta ngqo ikhwalithi kanye nenani eliphelele lezindleko maqondana nokusebenza kahle kokuqhumisa isihlabathi, ukumbozwa kwebhande, ukupenda, amandla e-kinetic kanye nokusetshenziswa okunamandla. Ngokukhishwa okusha kwe-coating protection performances standard (PSPC), kunesicelo esiphezulu sekhwalithi yokuqhumisa isihlabathi. Ngakho-ke, ikhwalithi yamatshe ensimbi ibaluleke kakhulu ekuqhumiseni isihlabathi.

Ama-granules angular e-sandblasting Container
Ukuqhuma kwesihlabathi okugobile emzimbeni webhokisi lesitsha ngemva kokushisela. Hlanza ijoyinti elishisiwe futhi ngesikhathi esifanayo ubangele ukuthi ubuso bomzimba webhokisi bube nobulukhuni obuthile futhi wandise umphumela wokupenda wokulwa nokugqwala, ukuze ukwazi ukusebenza isikhathi eside phakathi kwemikhumbi, i-chassis, imoto yezimpahla kanye nezimoto zesitimela.
Insimbi egobile yomshini kagesi wasensimini wokuqhumisa isihlabathi.
Umkhiqizo kagesi wasensimini unesicelo esikhethekile sokulungiswa kobuso obuqinile nokuhlanzeka. Ngemva kokwelashwa kobuso bensimbi egobile, kumele babhekane noshintsho lwesimo sezulu ngaphandle isikhathi eside. Ngakho-ke, ukuqhuma kwesihlabathi se-angular grit ebusweni kubaluleke kakhulu.

Itshe eliqoshiwe lensimbi eliqoshiwe le-granite kanye netshe eliqoshiwe eliqoshiwe
Ukusika amatshe ngokusebenzisa i-granite cutting steel grit kanye ne-stone cutting grit evela ekugelezeni kwamanzi. Enqubweni yokusika, i-stone saw grit ayinazo izinguquko zamakhemikhali futhi inezinzuzo zokungathandi ukusebenza kwamakhemikhali kanye nokusebenza ngokomzimba kwezinto zamatshe, akukho ukuguquka kokushisa, ukuciba okuncane, ukunemba okuphezulu, indawo yokusika ebushelelezi, ukuhlanzeka kanye nokungabi nokungcola, njll.

I-Grit yensimbi engu-angular yokuqhuma kwesihlabathi se-Locomotives
Ngemva kokuqedela ukwenziwa noma ukulungiswa, ubuso bezinqola kumele bupendwe (kufaka phakathi i-undercoat, i-middle coating, i-finishing coating nokunye), ukuze kuthuthukiswe ukubukeka kwangaphandle kwezinqola kanye nokuphila kokusebenza kwazo. Ukukhethwa kwe-grit yensimbi e-angular kubaluleke kakhulu ekuphathweni kwendawo, okuthinta ukusebenza kwe-coating kokulwa nokuqhekeka, ukumelana nokungena kanye nokungashisi.

I-grit yensimbi e-angular yesakhiwo sensimbi
Esakhiweni sensimbi, ijubane lokugqwala lihlobene kakhulu nomswakama womoya kanye nokwakheka kanye nenani lokungcola emoyeni. Ukuze kwandiswe isikhathi saso sokusebenza, isakhiwo sensimbi kumele sidinge ukwelashwa kwendawo yokuqhumisa insimbi e-Angular steel grit, bese kufefa ukuze kwakhiwe ifilimu evikelayo ebusweni bensimbi ukuvimbela nokunciphisa ukugqwala kwensimbi.

Umkhiqizi Wensimbi Yensimbi Yokuqhumisa Inhlabathi Yemishini Yezimbobo
Ukwakhiwa kwechweba lechweba kusebenzisa isakhiwo sensimbi kakhulu. Ngakho-ke, isicelo sokulwa nokugqwala kwesakhiwo sensimbi siphezulu kakhulu. Imishini yechweba ivame ukubhekana nendawo ekhethekile. Isibonelo, indawo enomswakama yomoya wasolwandle, ebangela ukuthi izakhiwo zesakhiwo sensimbi zithole ukugqwala okujulile. Uma kunjalo, kudingeka ukuqhumisa isihlabathi kanye nokugqoka okuhambisanayo ukuze kuvikelwe imishini yechweba. Ngakho-ke ukukhiqizwa kwetshe lensimbi elihle kubaluleke kakhulu.
