Njira zochotsera dzimbiri zomwe zimagwiritsidwa ntchito m'sitima zimaphatikizapo kuchotsa dzimbiri pamanja, kuchotsa dzimbiri pamakina ndi kuchotsa dzimbiri ndi mankhwala.
(1) Zida zowononga pamanja zikuphatikiza nyundo yopukutira(impa code:612611,612612), fosholo, scraper (impa code 613246),Scraper Angle Double Ended(impa code:613242), zitsulo waya burashi, etc. zambiri mawanga wandiweyani dzimbiri. kumasulidwa ndi nyundo ndiyeno kuthetsedwa ndi fosholo.Chifukwa cha kuchuluka kwa ntchito, kuchepa kwachangu, nthawi zambiri 0.2 ~ 0.5m2 / h, malo owopsa, zimakhala zovuta kuchotsa zinyalala monga oxide sikelo, zotsatira zoyipa za derusting, ndipo ndizovuta kukwaniritsa ukhondo ndi roughness zomwe zafotokozedwa. adasinthidwa pang'onopang'ono ndi njira zamakina ndi mankhwala M'malo mwake.Komabe, njirayi imagwiritsidwa ntchito nthawi zambiri pokonza zombo, makamaka pokonza zolakwika zam'deralo;Manual derusting idzagwiritsidwanso ntchito pazigawo zomwe zimakhala zovuta kuzifikitsa ndi makina a derusting, monga ma cabins opapatiza, ngodya ndi m'mphepete kumbuyo kwa gawo lazitsulo ndi madera ena omwe ali ndi ntchito yovuta.
(2) Pali zida zambiri ndi njira zowonongera makina, makamaka motere.
1. Small pneumatic kapena magetsi derusting.Imayendetsedwa makamaka ndi magetsi kapena mpweya woponderezedwa ndipo imakhala ndi chipangizo choyenera chodulira kuti chizitha kusuntha mobwerezabwereza kapena kuzungulira kuti ikwaniritse zofunikira zanthawi zosiyanasiyana.Mwachitsanzo, Magetsi ngodya chopukusira ndi zitsulo waya brush, pneumatic singano jet chisel (impa code: 590463,590464), pneumatic derusting brushes (impa code: 592071), pneumatic makulitsidwe nyundo (impa code: 590382), mtundu dzino rotary chipangizo, etc. ndi zida theka mechanized.Zida ndizopepuka komanso zosinthika.Amatha kuchotsa dzimbiri ndi zokutira zakale kwathunthu.Iwo akhoza roughen ❖ kuyanika.Kuchita bwino kumakhala bwino kwambiri poyerekeza ndi derusting yamanja, mpaka 1 ~ 2M2 / h, koma sangathe kuchotsa sikelo ya oxide, ndipo kuuma kwapansi kumakhala kochepa, sikungakwaniritse chithandizo chamankhwala apamwamba kwambiri, ndipo magwiridwe antchito ndi otsika. kuposa mankhwala opopera.Itha kugwiritsidwa ntchito pagawo lililonse, makamaka pakukonza zombo.
2. Kuphulika kwa kuwombera (mchenga) kuwononga.Zimapangidwa makamaka ndi kukokoloka kwa tinthu tating'onoting'ono kuti tikwaniritse ukhondo komanso roughness yoyenera.Zidazi zikuphatikizapo makina otsegula kuwombera (mchenga), kuphulika kwa kuwombera (mchenga) ndi makina owombera (mchenga).Kuwombera kotsegula Makina (mchenga) amagwiritsidwa ntchito kwambiri ndipo amatha kuchotsa zonyansa zonse pamtunda wazitsulo, monga oxide scale, dzimbiri ndi filimu yakale ya utoto.Ili ndi mphamvu yowononga kwambiri ya 4 ~ 5m2 / h, digiri yapamwamba yamakina komanso khalidwe labwino losokoneza.Komabe, ndizovuta kuyeretsa malowo chifukwa zotayira sizingasinthidwenso nthawi zambiri, zomwe zimakhudzanso ntchito zina.Choncho, ili ndi kuwonongeka kwakukulu kwa chilengedwe ndipo yaletsedwa pang'onopang'ono posachedwapa.
3. zotsukira kuthamanga kwambiri (impa code: 590736).Kugwiritsa ntchito mphamvu ya jet yamadzi yothamanga kwambiri (kuphatikiza abrasive akupera) ndi kupukuta kwamadzi kumawononga kudzimbirira kwa dzimbiri ndi zokutira ku mbale yachitsulo.Imadziwika ndi kusakhala ndi kuipitsidwa kwa fumbi, kusawonongeka kwa mbale yachitsulo, kumapangitsa kuti ntchitoyo ikhale yabwino kwambiri, mpaka kupitilira 15m2 / h, komanso mtundu wabwino wa derusting.Komabe, mbale zitsulo pambuyo derusting n'zosavuta dzimbiri mmbuyo, choncho m'pofunika ntchito wapadera chonyowa derusting ❖ kuyanika, amene amakhudza kwambiri ❖ kuyanika kwa zokutira ambiri ntchito.
4. Kuwombera kuphulika-Makina owonjezera amagetsi (impa code: 591217,591218), sitimayo scaler (impa code: 592235,592236,592237) , dzimbiri lamagetsi kuchotsa pamwamba kuyeretsa macine, lalikulu dera sitimayo makulitsidwe makina 1010Vt,42Vt, 42 VT). kuphulitsa ndiko kugwiritsa ntchito chopondera chothamanga kwambiri kuti aponyere abrasive pamwamba pazitsulo kuti akwaniritse cholinga chochotsa dzimbiri.Ndi njira yotsogola yamakina yopangira dzimbiri kuchotsa zida zachitsulo.Sikuti imakhala ndi mphamvu zambiri zopanga, komanso imakhala ndi mtengo wotsika komanso wokwera kwambiri.Ikhoza kuzindikira kugwira ntchito kwa mzere wa msonkhano popanda kuwononga chilengedwe, koma ikhoza kuchitidwa m'nyumba.
(3) Chemical derusting makamaka njira derusting ntchito anachita mankhwala pakati asidi ndi okusayidi zitsulo kuchotsa zinthu dzimbiri pamwamba zitsulo, ndiye otchedwa pickling derusting akhoza opareshoni mu msonkhano.
