1. Iwepu nchara akwụkwọ ntuziaka: Iji akwụkwọ ntuziaka dị ka akwụkwọ ígwè, scraper, spatula, na brush waya.Usoro a bụ nnukwu ọrụ ike, obere mmepụta mmepụta ihe, mana ọrụ dị mfe ma na-agbanwe agbanwe, ka na-anabata ya.

2. Mechanical nchara mwepụ: Iji mmetụta na esemokwu nke n'ibu ike wepụ nchara.Igwe a na-ejikarị eme ihe na-agụnye ahịhịa ikuku, egbe iwepụ nchara, ahịhịa eletrik, wheel ájá eletrik, wdg. Enwere ike ịkwanye obere akụkụ ígwè n'ime bọket jupụtara na ájá odo ma ọ bụ ibe osisi ma na-agagharị na ọsọ nke 40-60 rpm.Site nkukota esemokwu, elu mmepụta arụmọrụ na ezi àgwà nchara mwepụ àgwà, nke e ọtụtụ ebe.

3. Injection nchara mwepụ: Kwadoro na n'ibu centrifugal ike ma ọ bụ abịakọrọ ikuku na elu nrụgide mmiri, fesa abrasive (aja ma ọ bụ ígwè bọọlụ) n'ime workpiece elu na a elu na-agba site a pụrụ iche nozulu, na-ewepụ unyi (gụnyere mebiri emebi ochie agba akpụkpọ anụ. ) na corrosion na ike mmetụta ya na esemokwu ya, na-arụ ọrụ dị elu na mmepụta ọgwụgwọ dị mma.A na-edozi elu elu igwe nke ájá ájá ka ọ na-eme ka ike ejikọta nke mkpuchi na elu ígwè.Ma adịghị ike ya agaghị agafe 1/3 nke ọkpụrụkpụ mkpuchi.Uzo esi ewepu nchara nchara nke a na-ejikarị eme ihe gunyere uzuzu uzuzu, mgbawa aja nke uzuzu, uzuzu na-adighi uzuzu na mgbawa mmiri aja aja.

4. Chemical nchara mwepụ: Iji acid ngwọta na ígwè oxides, igbari na bee n'elu nchara oyi akwa iji nweta nzube nke nchara mwepụ.Ya mere, a makwaara ya dị ka "ịsacha acid" na mgbochi nchara.Enwere ọtụtụ usoro maka iwepụ nchara kemịkal, na-abụkarị ihe ngwọta sulfuric acid nke 7% ruo 15% (ma ọ bụ 5% nnu tebụl) ka a na-eji dị ka ihe ngwọta na-ewepụ nchara nchara.Iji gbochie sulfate corrosion nke ígwè, enwere ike ịgbakwunye obere ihe mgbochi corrosion dị ka rodine na thiourea.Na mgbakwunye, ọ nwekwara ike iji phosphate acid, nitrate acid, hydrochloric acid na ihe ndị ọzọ na-eme ka acid dị iche iche na-asachapụ na nchara nchara.Enwere ọtụtụ ụzọ nke pickling, na-ejikarị usoro ịsa acid impregnated, ịgba pickling usoro.E wezụga nke ahụ, ude acid, dabere na ọnọdụ ụfọdụ.
