Kodi fumbi abrasive?

Abrasive zipangizo yodziwika ndi luso la ogwira ntchito makina. Ndi awo dothi thandizo kuchotsa, kuthetsa kuukira kubala pamalo oyera ndi dzimbiri ndi utoto. Ntchito mchitidwe Ndipotu, ndi abrasive granules, amene angathe kukhala akalumikidzidwa osiyana ndi makulidwe. Mtundu umodzi wa granules amenewa ndi abrasive fumbi, amene akhoza kukhala chiyambi fakitale kapena chifukwa cha yobwezeretsanso zinyalala ndi T D..

General zokhudza fumbi abrasive

Fumbi mwina ndi makhalidwe osiyana ndi chiyambi, koma nthawi zambiri ichi ndi mankhwala oipa processing zitsulo ndi matabwa mankhwala. Childs, ufa abrasive adzamasulidwa m'kati akuchita umapezeka ndi kupukuta ntchito. Fumbi ikhoza kupangidwa ndi processing wa pamalo banja, ndipo mu mabuku zikuluzikulu kukhazikitsa ntchito mu mlingo mafakitale. Nthawi zonse zitsulo abrasive fumbi anapanga chifukwa cha kuwonongedwa kwa chithandizo zinthu zazikulu. Ambiri zinyansi izi kusiya mawilo akupera ndi kanthu makina pa chandamale pamwamba kuchitiridwa. Pamene fumbi zimenezi ndi zitsulo - zambiri ophatikizana nyimbo kuti mulinso particles abrasive thanthwe.

zakuthupi zikuchokera

Processing abrasives makamaka ongoyendayenda mankhwala a akakhala zitsulo. Izo zikhoza kukhala mbali tsogolo zida makina, galimoto zikuluzikulu, komanso zomangira. Maziko a zikuchokera aliyense ndipamene fumbi chitsulo - a dongosolo la 30%. Buku lachiwiri ndi zambiri zili wa okusayidi zotayidwa - aluminiyamu, ngakhale ubwino wake akhoza zosiyanasiyana. The sekondale constituent zinthu abrasive ufa monga phosphorous, Arsenic, faifi tambala, manganese, chromium ndi D. ngati. Nthawi zambiri zimadalira mmene pamwamba ntchito ubwenzi fumbi abrasive. Zikuchokera allocated osakaniza zambiri zikuphatikizapo zinthu za lonse, dzimbiri ndi utoto zokutira akale. Kwenikweni, kulimbana ngati accretions zambiri anagwiritsa ntchito njira abrasive kuchotsa.

Zosiyanasiyana fumbi abrasive

Gawo mogwirizana ndi mfundo zingapo za kulekana kwa particles abrasive. Mu njira zambiri amadalira njira kugwiritsa ntchito mfundo mankhwala. Mwachitsanzo, ngati zida akupera ndi nozzle mu mawonekedwe a bwalo, fumbi chifukwa angatchedwe pakachitsulo. Komanso kuchita ntchito sandblasting makina, amene poyamba ntchito wosweka mbewu abrasive. Iwo akhoza zimasiyana-siyana ukulu ndi mawonekedwe, koma vuto akanali yemweyo - kuchotsa zokutira pamwamba kapena zosafunika kuonetsetsa kusalala kwa workpiece lapansi. The processing yomaliza ya mankhwala Pankhaniyi adzakhala zitsulo abrasive fumbi, koma mawonekedwe olakwika. Nkofunika kuzindikira kuti, mosiyana ndi mankhwala pakachitsulo, fumbi akhoza kugwiritsidwa ntchito mu ntchito wotsatira, ndipo ntchito monga ufa chachitsulo kwa akupera.

makhalidwe a

Magawo ndi katundu wa fumbi anapanga anatsimikiza ndi zikhalidwe za ntchito ndi zipangizo ntchito. Mwachitsanzo, mu makina zomanga mabizinezi opangidwa makina amene amafuna mkulu-mwatsatanetsatane kutsirizitsa kali kuti kufunika mtundu zojambula. Mu processing pakati pa akhazikitsa ndi mankhwala adagulung'undisa aumbike krupnofraktsionnaya fumbi amene miyeso akhoza zimasiyana microns 5 mpaka 10. Kawirikawiri analandira ndi evaporation wa sikelo kwambiri ya dongosolo la 20% kulemera. Wapakati wa totere mabizinezi fumbi umuna ndi 200 ga pa 1 tani ankachitira zitsulo kugudubuzika. Ngati Komanso ntchito ndi scarfing, voliyumu ya zinyalala abrasive akhoza kwambiri kuonjezera. Pamene akuchita ntchito mphero m'mavoliyumu fumbi ang'onoang'ono abrasive popangidwa ndi khalidwe yaing'ono nusu. Chotero fumbi ali ake awiri 0.5-1.5 microns. Koma sindikuganiza kuti kulekana kwa particles yabwino ndi abwinopo kusiyana zikuluzikulu. Choyamba, nusu lalikulu la fumbi m'zigawo facilitates ntchito. Kachiwiri, kuyambira mfundo chithandizo cha, fumbi losalala ndi ngozi dongosolo kupuma. Tsopano m'pofunika kupenda mwatsatanetsatane n'chifukwa chiyani m'pofunika kuthana ndi Kugawilidwa kwanthaka ufulu zinyalala abrasive pa processing.

Fumbi abrasive ndi oopsa?

Popanda bwino fumbi m'zigawo dongosolo m'badwo wa fumbi zitsulo n'kogwiritsa kufalitsa mpweya wa danga logwira ntchito. Wotere zambiri kukhala kuntchito matenda fitters. matenda kungaphatikizepo pneumoconiosis, fumbi chifuwa, mphumu, ndi zina zotero. D. Kukula kwa matenda angakhale chotsatira cha zonse m'mapapo mkwiyo ndi tinthu abrasive ku processing zipangizo, workpieces ndi zinthu za dongosolo la. Choncho, n'kofunika kuti poyamba bungwe dongosolo kuti adzaonetsetsa ogwira kuchotsa fumbi abrasive mwachindunji mu malo antchito. Malinga ndi kukula ndi kantchito kachitidwe amenewa amachitika mogwirizana ndi mfundo zosiyana. Izi zikhoza kukhala muyezo mafakitale zingalowe m'malo zotsukira, olumikizidwa kwa makina akupera, ndi mpweya mafakitale.

njira kuchotsa

Small abrasive zinthu kukonzedwa ndi ntchito akupera makina chuma ambiri Akusonkhanitsa kudzapereka mu atsamunda wapadera. Ndi zokwanira kuganizira njira kuti muzithera kayendedwe ka fumbi. Nthawi zambiri vutoli anathana ndi ndege, wettable ndi madzi. Madzi chophimba n'kuliza ufa mu sump ndi wokonzeka ndi fyuluta. Lotsatiranso ndi umatsuka madzi oyera kuchotsa mbali pogamula fumbi. Kwa dzuwa kwambiri akhoza kupereka njira kuda mpweya dongosolo kuti chingamulepheretse ndi mwachisawawa kubalalika tinthu tina take tating'onoting'ono. Pomanga akugwiritsa ntchito ya kale zingalowe m'malo zotsukira fumbi abrasive, imene pa nthawi ya Kugawilidwa kwanthaka ndi tinthu imayamwa iwo mu chidebe wapadera, kuteteza zabalalika. dongosolo More imayenera kulimbana zinyalala kumva kuwawa komanso idzagwiritsa ntchito otaya mpweya. Mwachitsanzo, mu utuluke chiphunzitso mwina opareshoni ejector, amene anaika pakati pa olekanitsa thupi.

Pomaliza

Chiphunzitso cha particles abrasive ndi chodabwitsa anatipatsira, osati mu njira kusinja ndi kupukuta. Ngakhale ambiri "chopukusira" kudula zitsulo kumathandiza kuti mapangidwe zinthu zimenezi. Izo Sizotheka kuti kupereka dongosolo limene fumbi abrasive kuchotsedwa basi. Makamaka mu chilengedwe zoweta, pamene kamodzi kukonza ntchito makamaka izi kugula zingalowe m'malo chomwecho kosathandiza. Zikatero ndi kudziyesa woyamba wa zonse munthu chitetezo kupuma. Pankhani kuteteza pamalo chipinda, izo zizikhala mwa malo patsogolo ntchito kuphimba ndi zojambulazo. Ndipo ndi lamulo kukonza mpweya - osachepera zenera mu msewu.
