Yintoni uthuli esirhabaxa?

izinto Abrasive luphawulwa amandla amanyathelo ngoomatshini olusebenzayo. Ngenxa yabo ukungcola uncedo yazisusa, sizani uhlaselo ukuvelisa iindawo ezihlambulukileyo nxamnye irusi kunye nepeyinti. Ukusebenza element, enyanisweni, kuba granules esirhabaxa, apho unokuba iimilo kwaye abe nobukhulu obahlukeneyo. Olunye uhlobo granules enjalo uthuli esirhabaxa, nto leyo inokuba mveliso imvelaphi okanye ngenxa kwakhona inkunkuma kunye t. D.

ulwazi ngokubanzi malunga uthuli esirhabaxa

Uthuli ukuze iimpawu ezahlukeneyo kunye nemvelaphi, kodwa ke kwiimeko ezininzi le yimveliso engathandekiyo zokulungisa isinyithi kunye nemithi imveliso. Ngokuqhelekileyo, le umgubo esirhabaxa ngesi inkqubo ukwenza sokusila kunye nokusebenza ipolishi. Uthuli enokuveliswa nokulungiswa imiphezulu indlu, yaye ininzi kakhulu ekusetyenzisweni kwe ukusebenza ngendlela mveliso. Kuzo zombini ezi meko zentsimbi uthuli esirhabaxa wabumba ngenxa yokwaphuka izinto eziphambili unyango. Inkoliso yezi amanxuwa ushiye iivili makasilele ngesenzo ngoomatshini kumphezulu target ukuba aphathwe. Xa olu uthuli alusoloko metal - ngokuqhelekileyo kudityaniswe ezaqanjwa ezibandakanya amasuntswana esirhabaxa elulwalweni.

kuqamba ezibonakalayo

abrasives Iqhubekekisa becala zibethwa imveliso ayoni. Isenokuba iindawo elizayo izixhobo ngomatshini, iimoto kunye amacandelo, kwakunye nezixhobo zokwakha. Isiseko kuqamba enza yentsimbi uthuli - malunga nama-30%. Umqulu yesibini idla ngokuba umxholo we-aluminiyam oxide - alumina, nangona umgangatho walo anokwahluka. Iziqalelo abamelwe eziziisekondari emigutyeni esirhabaxa ziquka phosphorus, iarseniki, nickel, manganese, chromium kunye ezifana. D. ixhomekeke kakhulu kwindlela kwindawo osebenzela ozibandakanye yi eluthulini esirhabaxa. Ukwakhiwa umxube eyabelwe rhoqo kuquka iimpawu isikali, umhlwa kunye Ipeyinti yepeyinti endala. Eneneni, ukuba silwe accretions enjalo aphela rhoqo kusetyenziswa njengobuchule ukususwa esirhabaxa.

Imihlobo uthuli esirhabaxa

Classification lusekelwe kwimigaqo eziliqela ukungcola amasuntswana esirhabaxa. Ngeendlela ezininzi nabo baxhomekeke indlela isicelo kwemathiriyeli imithi. Umzekelo, ukuba kukho izixhobo makasilele kunye umlomo ekwimo isangqa, uthuli ngenxa ingabizwa lesilicon. Kwakhona kwenziwa ukusetyenziswa koomatshini sandblasting, leyo esasifudula iinkozo esirhabaxa batyumke. Baya ziyahluka ubukhulu kunye nokumila, kodwa ingxaki ihlala efanayo - ukukhutshwa Ipeyinti kumphezulu okanye engeyomfuneko ukuqinisekisa ngobuqhophololo le workpiece. Processing yokugqibela imveliso kule meko bekuya kuba metal uthuli esirhabaxa, kodwa uhlobo lothando. Kubalulekile ukuqaphela ukuba, ngokungafaniyo iikhompawundi lesilicon, loo uthuli ingasetyenziswa kwimisebenzi elandelayo, kwaye isetyenziswa ngumgubo metal ukugaya.

iimpawu

Ipharamitha neempawu uthuli kwakhiwa emiselwe imiqathango imisebenzi kunye nezinto ezisetyenziswayo. Ngokomzekelo, xa umatshini-ukwakha ngamashishini yavelisa iimatshini ezifuna ophezulu-ngqo kugqityiwe iindawo kwifomathi lwezibalo ezinqwenelekayo. Kulo processing phakathi imiqulu imveliso liqengqiwe ezikhandelwa krupnofraktsionnaya uthuli ogama dimensions ziyahluka ukusuka microns-5 ukuya kweli-10. Kudla kokuba efunyenwe yi komphunga kanye isikali komyalelo ka-20% ubunzima. I-avareji komsi amashishini uthuli malunga 200 g nganye 1 ngetoni ngayo ukunikezela metal. Ukuba wasebenzisa Ukongezelela kunye scarfing, umthamo wenkunkuma esirhabaxa kungandisa kakhulu. Xa usenza nokugaya imithamo ezincane uthuli esirhabaxa ezenziwa umlinganiswa lwamaqhezu encinane. amasuntswana nothuli ezinjalo microns bayo ububanzi 0.5-1.5. Kodwa musa ukucinga ukuba ukwahlulwa amasuntswana emihle ikhuseleke ngaphezu ezinkulu. Okokuqala, inxalenye enkulu ukususa uthuli kube lula ukusebenza. Okwesibini, ukususela kwindawo yezonyango lwembono, nothuli na eyingozi isixokelelwano sokuphefumla. Ngoku kuyimfuneko ukuba ukuhlalutya ngokweenkcukacha umbuzo kutheni kuyimfuneko ukujongana lo wasimahla inkunkuma esirhabaxa ngexesha processing.

Uthuli esirhabaxa kuyingozi?

Ngaphandle sizukulwana eyiyo inkqubo nezokukhupha uthuli uthuli wentsimbi kuya kukhokelela nokusasazwa emoyeni indawo yokusebenza. Kwiimeko ezinjalo bavame izifo emsebenzini fitters. izifo anjalo angaquka pneumoconiosis, iphika uthuli, isifuba, njalo njalo. D. Uphuhliso Isifo inokuba sisiphumo eku- kwemiphunga rhoqo kunye amasuntswana esirhabaxa evela izixhobo processing, workpieces neziqalelo ngesakhiwo. Ngoko ke, kubalulekile ukuba aququzelele ekuqaleni inkqubo eya kuqinisekisa ukususwa olusebenzayo uthuli esirhabaxa ngqo kwindawo yokusebenza. Kuxhomekeke kwisayizi kunye neemeko zokusebenza ezi zixokelelwano ahlelwa ngokuvisisana nemigaqo ezahlukeneyo. Oku kube umgangatho ikharakhtha mveliso, uqhagamshele kumatshini lokusila, yaye umoya mveliso.

iindlela nokususwa

izinto ezincinane esirhabaxa kusingathwa ngokusebenzisa besila oomatshini eziphathekayo ngokuqhelekileyo iyaqokelelwa aphumayo abafuduki ezizodwa. Akwanelanga ukuba bacinge ngeendlela yokuhambisa intshukumo uthuli. Kwiimeko ezininzi, ingxaki isonjululwe moya, imigubo ngamanzi. Lathi ikhuselo Water uvuthela umgubo kulo sump, mayixhotyiswe lokucoca ulwelo. Okulandelayo kwakhona uhlamba izitya ngamanzi acocekileyo kude iinxenye yokusombulula uthuli. Kuba ngempumelelo enkulu na ukubonelela ngenkqubo channel idreyini eziya ukunqanda ukusasazeka random amasuntswana amancinane. Ekwakhiweni ngakumbi usebenzisa i vacuum cleaner esele zikhankanywe eluthulini esirhabaxa, ngelo xesha ulwabiwo amasuntswana yadika kuzo kwisingxobo ekhethekileyo, ukuvimbela uyachithachitha. nkqubo nephumelelayo yokulwa inkunkuma lingonakali nazo zibandakanya ukusetyenziswa kwemali lomoya. Umzekelo, kwi lokusetyenziswa kuqulunqo esebenza ejector, nto leyo ifakelwe embindini umzimba umahluli.

isiphelo

Ukusekwa kwamasuntswana esirhabaxa buyinto ezingenakuthintelwa, hayi nje kuphela kweli iinkqubo ukugaya ipolishi. Nokuba esiveza 'sokuhluza' nangokukrola ngesinyithi kunegalelo ukuyilwa izinto ezinjalo. Oku akusoloko kusenzeka ukuba ukunika inkqubo apho uthuli esirhabaxa zisuswe ngokuzenzekelayo. Ingakumbi kwindawo ekhaya, xa imisebenzi ngexesha elinye yokulungisa ingakumbi kule ukuthenga zidle efanayo usebenze. Kwiimeko ezinjalo kuyimfuneko ukuba bacinge ngayo yonke ukhuseleko yokuphefumla zobuqu. Ngokumalunga ukukhuselwa imiphezulu igumbi, kuya kuba aphume ndawo ngaphambi kokuba umsebenzi yokugubungela nabo alumuniyam eliqinileyo. Kwaye kunyanzelekile ukuba amalungiselelo umoya - ubuncinane ngefestile esitratweni.
