Kuyini uthuli olwalwenza?

izinto Abrasive libhekene ikhono ngempumelelo isinyathelo lokukhanda. Ngosizo khipha yabo ukungcola, khulula ukuhlaselwa ukukhiqiza evele ahlanzekile ngokumelene nokugqwala nopende. Ukusebenza isici, eqinisweni, kuba elimbudumbudu olwalwenza, okungaletha ezihlukile nobukhulu. Olunye uhlobo lokudla elimbudumbudu ezinjalo kuba uthuli olwalwenza, okungaba imboni imvelaphi noma kube umphumela kabusha imfucuza kanye t. D.

ulwazi olujwayelekile mayelana uthuli olwalwenza

Uthuli angase abe nezici nezizinda, kodwa ezimweni eziningi lokhu umkhiqizo engathandeki kucutshungulwa isizinda kanye nokhuni imikhiqizo. Ngokuvamile, powder olwalwenza Kukhululwa inqubo ekwenzeni ukugaya wokucwebezelisa imisebenzi. Uthuli kungenziwa elakhiwe nokucutshungulwa evele yasendlini, futhi omningi ukuqaliswa ukusebenza ngezinga ezimbonini. Kuzo zombili lezi zimo steel uthuli olwalwenza kwakhiwa ngenxa yokucekelwa phansi main impahla ukwelashwa. Iningi lezi imfucumfucu ushiye amasondo ukugaya ngesenzo mechanical phezu kwelitshe ngayo. Uma lokhu uthuli akuyona njalo metal - ngokuvamile kuhlanganiswe izingoma ukuthi aphinde abandakanye izinhlayiya olwalwenza edwaleni.

ukwakheka impahla

Icubungula Abrasives ikakhulu bavezwa imikhiqizo ye metal ayoni. Kungaba izingxenye esizayo umshini amathuluzi, izimoto kanye izingxenye, kanye zokwakha. Isisekelo sanoma ibuphi Ukwakheka yakha yensimbi uthuli - komyalelo wokungabi 30%. Umqulu wesibili ngokuvamile okuqukethwe aluminiyamu oxide - alumina, nakuba izinga layo Ungase futhi ziyahlukahluka. I yesibili abamelwe izakhi izimpushana olwalwenza zihlanganisa i-phosphorus, i-arsenic, nickel, manganese, chromium nokunye okunjalo. D. Okuningi kuxhomeke endleleni ebusweni zokusebenza wahlanganyela ngu uthuli athile. Ukwakheka ingxube labelwe ngokuvamile ifaka izinto esikalini, nokugqwala upende ezinengilazi ubudala. Empeleni, ukuze ulwe accretions enjalo ngokuvamile sisetshenziswa inqubo ukususwa athile.

Izinhlobonhlobo uthuli olwalwenza

Ukwahlukanisa kusekelwe ezimisweni eziningana ukwehlukana izinhlayiya athile. Ngezindlela eziningi bathembele indlela kwesicelo of indaba ukwelashwa. Ngokwesibonelo, uma ama-apharathasi ukugaya nge umlomo wombhobho ngesimo embuthanweni, uthuli okuholela kungenziwa ngokuthi silicon. Futhi wayekwenza ukusetshenziswa imishini sandblasting, ebihlelwe ekuqaleni esetshenziswa ochotshoziwe okusanhlamvu athile. Abakwazi ziyahlukahluka ngobukhulu futhi ukuma, kodwa inkinga ayiguquki - ukususwa kwamanzi ezinengilazi noma ezingadingekile ekuqinisekiseni olubushelelezi ka workpiece. I processing yokugcina umkhiqizo kulesi simo kungaba kwensimbi uthuli olwalwenza, kodwa ifomu angahleliwe. Kubalulekile ukuqaphela ukuthi, ngokungafani Silicon compounds, uthuli ezinjalo ingasetshenziswa imisebenzi okwalandela, futhi lisetshenziswa njengendlela powder metal ukugaya.

izici

Amapharamitha nezakhiwo uthuli kwakhiwa kunqunywa izimo zokusebenza ezisetshenziswa. Ngokwesibonelo, umshini wokwakha amabhizinisi ekhiqizwa imishini ezidinga ephezulu ukucacisa yokuqedela ezishelelayo kuya wayefisa format weJiyomethri. kwakhiwa Kulesi ukucubungula phakathi imiqulu kanye umkhiqizo iphuma is krupnofraktsionnaya uthuli kabani Ubukhulu ziyahlukahluka kusuka microns 5 kuya ku-10. Ngokuvamile it is etholwe ukuhwamuka kabi yibo kanye esikalini komyalelo wokungabi 20% isisindo. Isilinganiso esinjalo amabhizinisi uthuli ekushayweni imayelana 200 g ngalinye 1 ton of iphathwa ugingqe metal. Uma ngaphezu kwalokho esetshenziswa futhi scarfing, ivolumu imfucuza olwalwenza ungakwazi ukwandisa. Uma wenza nokugaya e imiqulu ezincane uthuli olwalwenza ezakhiwe ingxenyenamba uhlamvu encane. uthuli ezinjengalezi yayo ubukhulu 0.5-1.5 microns. Kodwa ungacabangi ukuthi ukuhlukana kwazo izinhlayiya emihle iphephe kakhudlwana kunemithi ezinkulu. Okokuqala, ingxenyenamba enkulu isizinda uthuli kusiza ukusebenza. Okwesibili, njengoba umbono wezokwelapha, nothuli kuyingozi ukuba umgudu wokuphefumula. Manje kubalulekile ukuhlaziya ngokuningiliziwe umbuzo wokuthi kungani kubalulekile ukubhekana ukwabiwa khulula imfucuza olwalwenza phakathi kwenqubo.

Uthuli olwalwenza kuyingozi?

Ngaphandle kahle uthuli isizinda uhlelo isizukulwane uthuli metal nakanjani kuyoholela ukusakazwa emoyeni isikhala zokusebenza. Ezimweni ezinjengalezi ngokuvamile ukuthuthukisa emsebenzini izifo fitters. izifo okunjalo kungahlanganisa pneumoconiosis, uthuli ukucinana kwemigudu yokuphefumula, isifuba somoya, nokunye. D. ukuthuthukiswa isifo kungaba umphumela we njalo wamaphaphu ukucasuka nezinhlayiyana olwalwenza processing amathuluzi, workpieces netakhiwo isakhiwo. Ngakho-ke, kubalulekile ekuqaleni ukuhlela uhlelo oluzoqinisekisa ukususwa ngempumelelo ngothuli olwalwenza ngqo ezindaweni zokusebenzela. Kuye ngobukhulu kanye nezimo abasebenza ngaphansi kwazo lwalezi nhlelo ihlelwe ngokuvumelana nezimiso ezahlukene. Lokhu kungaba ejwayelekile zezimboni cleaner wezindlu, exhunywe kwi-umshini ukugaya, nokushaya komoya izimboni.

izindlela ukususwa

izakhi ezincane olwalwenza kusetshenzwe ngokusebenzisa ukugaya imishini impahla ngokuvamile eqoqwe futhi lingashajwa e izifiki ekhethekile. Kuyinto ngokwanele ukuba zicabange ngezindlela kusiteshi ukuhamba uthuli. Ezimweni eziningi, inkinga isixazululekile ngu izindiza, wettable amanzi. Amanzi umgubuzelo ashaye powder phakathi sump, ifakwe zokuhlunga. Okulandelayo futhi ube izona ehlanzekile amanzi away izingxenye sokuxazulula uthuli. Benta kahle kakhulu anganikeza isiteshi abakhwabanisi ukupholisa uhlelo ukuthi kuzovimba futhi bahlakazwa kwangasala okungahleliwe izinhlayiya ezincane. Ngo ukwakhiwa ziba mandla ekusebenziseni le sekushiwo cleaner wezindlu othulini olwalwenza, lolo ngesikhathi sokuhlwanyelwa kwesabelo izinhlayiya sucks kubo esitsheni akhethekile, ekuvimbeleni chitha. uhlelo Okuningi kahle ukuze ulwe nemihuzuko imfucuza futhi ezihilela ukusetshenziswa komoya. Ngokwesibonelo, e notshwala ekwakhiweni ingase eziqhutshwa ejector, okuyinto efakwe maphakathi umzimba isihlukanisi.

isiphetho

Ekwakhiweni izinhlayiya olwalwenza buyinto engenakugwemeka, hhayi kuphela e izinqubo ukugaya futhi wokucwebezelisa. Ngisho ejwayelekile "grinder" ekunqunyweni metal kunomthelela kumiswa izakhi enjalo. Akukhona njalo kungenzeka ukunikeza uhlelo lapho uthuli olwalwenza zisuswe ngokuzenzakalelayo. Ikakhulukazi imvelo yasekhaya, lapho yesikhathi esisodwa ukulungisa imisebenzi ikakhulukazi le ukuthenga cleaner efanayo engeke asebenze. Ezimweni ezinjalo kubalulekile ukucabanga kuqala kunazo zonke somuntu siqu Ukuvikelwa zokuphefumula. Ngokuphathelene Ukuvikelwa egumbini evele, ngeke kube aphume endaweni ngaphambi kokuba siye emsebenzini, uzinameke ucwecwe. Futhi kuba isibopho ukuhlela ukupholisa - okungenani ngefasitela emgwaqweni.
