Rust remover: Ukukhetha, isicelo

Rust - a "isifo" ezivamile izinsimbi. Lezi ngezinto eziqinile enemisebenzi elisizungezile. Zisetshenziswa ukudala ekhaya Imishini, izimoto, air zokuthutha, nokunye okuningi. Zonke okunamathiselwe obuqine kunabo bonke futhi wenza metal. Kodwa nakhu inkinga: ngokuhamba kwesikhathi, iningi lawo ukungenwa namachibi - ukugqwala. Material libhujiswa ngaphansi kwethonya imvelo, futhi idizayini iqala buba bubi nakakhulu. Kanjani ukulondoloza metal ezithile zokufa? Yini remover nokugqwala ukukhetha? Ake sihlole kulesi sihloko.

Ukususwa ukungcoliswa ukukhanya

I ngaphambili ukuthomba, kuba lula ukubhekana nayo. Uma umonakalo lingeliningi kakhulu phakathi velos metal esanele abalekele mechanical yokuhlanza indlela. Ukuze wenze lokhu, ungakwazi aphathe ebusweni nge ibhulashi elukhuni. Sanding kususa ebhuqwini ungqimba ukuletha metal ekuqhubekeni esiphelweni "ubovu."

Kufanele kuqashelwe ukuthi isinyathelo ukwelashwa mechanical isetshenziswa ulwe nokugqwala kugxilile ngaphambi kokufaka isicelo amakhemikhali ukuze kuzuzwe imiphumela engcono kakhulu. Ungasetha lokukhuhla enkulu njengoba ibhulashi elukhuni.

Avtoochistitel

Okuhle nokugqwala remover - wezindlu imoto metal. Leli thuluzi iyatholakala: ke angathengwa ngasiphi ezikhethekile emikhiqizweni izimoto esitolo. Ngaphambi kokufaka isicelo kutuswa ukuhlanza ebusweni nge ibhulashi elukhuni, ehlaselwe ukugqwala. Khona-ke sifunda camera agents 5 kwangu obukhulu, futhi bavunyelwe ukuba ume emva kwamaminithi ambalwa. Khona-ke izinsalela ukuba ageziwe ebusweni owomile ukoma. Uma nokugqwala akuhambile ngokuphelele, usuphinda.

Kufanele kukhunjulwe ukuthi iyiphi remover nokugqwala anobuthi. Ngokuvamile lokhu ingress acid elibangela eshe isikhumba. Sebenza isidingo sokugqoka amagilavu zokuzivikela, amagogolo futhi ngomshini. Ngaphezu kwalokho, ngeke kube engadingekile ukufunda ngokucophelela yokusetshenziswa futhi izinyathelo zokuphepha.

isixazululo esikhashana

Ngenxa yalokho, ucwaningo zabantu wadala eningi "ekhaya" zokupheka zokususa ukugqwala. Zisekelwe izinto okuyinto chaza yensimbi oxide kwakhiwa phezu kwensimbi zidilika. Homemade ketshezi nokugqwala remover ilungiselela iresiphi elandelayo:

• amanzi - 300 ml;
• ammonium - 50 g;
• 40% formalin - 250 g;
• caustic soda noma sodium hydroxide - 50 g

Hlanganisa izithako, kufanele buhlanjululwe ilitha lamanzi. Isixazululo yafakwa izakhi zensimbi, okuyinto babhekana ukugqwala (ejenti ukwelashwa surface ngeke isebenze). Shiya imizuzu 15-40, ngezinye izikhathi ukubukela inqubo. Susa izingxenye ngokushesha emva ukunyamalala ukugqwala. Khona-ke wageza kahle emanzini ashisayo bese eyomile ukoma. ukubukeka Original futhi zemvelo metallic ayebuthaka yibhange.

Acid ngokumelene nokugqwala

Kuyaziwa ukuthi acid bayakwazi chaza eziningi chemical compounds. I hydrated yensimbi oxide iyathinteka. Zokuhlanzwa qualitative akufanele asebenzise acid eqinile, ubusawoti kukhona hydrochloric, sulfuric, futhi wali band. Nokho, ukusebenzisa isixazululo ahlanzekile akuyona: they are kakhulu Ukuthoma. Acid umsebenzi nokugqwala kahle, uma sifaka inhibitor - ikhemikhali kubambezela ukusabela zamakhemikhali. Omunye kufinyeleleke kakhulu kuyinto methenamine.

Indlela ulula: kubalulekile ukuba sithathe noma yiziphi acid echazwe futhi alulaze ke ngamanzi ukwakha 5% isixazululo. Bese wengeza inhibitor ngayinye 0.5 amagremu ilitha liquid ngayinye. Surface iphathwa ukuthola izimali bakushiye isikhashana. Umsebenzi kalula babhekane hydrochloric, sulfuric noma wali band acid. Lapho ukuthenga inhibitor? Uma emakethe futhi okukhethekile ezitolo ungasiboni, sebenzisa lokhu iresiphi:

• amazambane eziqongweni walala ezintathu-litre imbiza (kufanele ugcwalise kwesigamu umthamo yayo);
• uthele acid ukumboza neziqu;
• 20 amaminithi ngenkuthalo ikhathaze okuqukethwe;
• sokukhipha ketshezi - vacuum metal futhi zilungele.

Kusho wali band acid

Isixazululo, wenza ngesisekelo wali band acid, enqanda nokugqwala ngendlela kunenzuzo kakhulu. Kusho iguqula nokugqwala, eliqinile enamathela ungqimba. Ngasiphi lokuhlushwa kufanele kube wali band acid? Kuphi uyithenga? Thola acid, kuhlanganise wali band acid, kungaba ezitolo noma iminyango ezimbonini-chemistry. Ukuze silungiselele i solution ngempumelelo, ukuguqulela hydrated yensimbi oxide ku enamathela esiqinile izinsimbi, kutuswa ukusebenzisa 15% noma 30% aqueous orthophosphoric isixazululo acid. I-ejenti okuholela sisetshenziswa ngu ibhulashi noma isifutho isibhamu nezinhlamvu ezivunyelwe some ngokuphelele.

Enye indlela ephumelelayo ekulweni 'ryzhinoy "ngesisekelo orthophosphoric acid iresiphi:

• butanol - 5 ml;
• tartaric acid - 15 ml;
• wali band acid - 1 ilitha.

Kungani wali band acid ngakho kuthinta ukugqwala? Zonke wachaza kalula ngokuya yokuthakwa kwamakhemikhali: Ishintsha oxide yensimbi e-phosphate, esiyingxenye uhlobo ifilimu phezu kwensimbi esivikela ke.

Ezinye izindlela ukuchayeka kumakhemikhali

Yiziphi ezinye izinto uzokwazi uqalise ngempumelelo ukugqwala? Mhlawumbe izindlela ezingaphezu elula ngeke amathuluzi anjenge:

• ingxube kaphala- okusamanzi (noma uketshezi petrolatum), futhi acidosis acid kule isilinganiso 2: 1;
• ziyoncibilika 100 ml amanzi, i-zinc chloride (5 g) kanye ikhethelo tartar (0.5 g);
• turpentine noma kerosine ukugqwala azinakwa.

Zonke lezi zindlela zinhle zokususa nokugqwala on imishini metal kanye nezinye izakhi "non-ezifuywayo" metal. Ukuze ukusetshenziswa ekhaya, zikhona izindlela eziningana elula kakhudlwana futhi ezingabizi kokukhipha i-plaque ginger:

• namafutha kafishi - isetshenziswa nokugqwala futhi ushiye isikhashana;
• ingxube ka citric acid kanye uviniga ngezabelo alinganayo ukuqeda ukugqwala egumbini lokugezela nokugqwala amabala ingubo, indlela sisetshenziswa imizuzu engu-20 bese zihlanjululwa isiponji kanzima;
• ka baking soda ukwenza slurry (ngokungeza ngamanzi) kanye isetshenziswa ebusweni metal, kusale ihora bese ugeza;
• isixazululo we oxalic acid: 6 tsp .. ziyoncibilika 300 ml amanzi, elicwiliswe okuholela ketshezi izakhi egqwalile isigamu sehora;
• baphuze "Coca-Cola" ubhekana nokugqwala ngenxa okuqukethwe wali band acid.

izindlela zokuvimbela

Ukususa nokugqwala kusuka metal - eside hhayi inqubo elula. Corrosion kungagwenywa esebenzisa ezinye izindlela okuyinto ukuvikela ebusweni ekulimaleni. Nazi izindlela ezimbalwa ewusizo, ukuvimbela ukwakheka nokugqwala:

• upharafini noma wax (20 g) ngesikhathi esifanayo-benzene (40 ml) kanye nekhambi okuholela - i izindlela ezinhle kakhulu ukuze bazivikele ukugqwala lokubaza namathuluzi;
• wax noma upharafini (10 g) kanye kaphalafini (30 ml) ukuvimbela okuvela kuyo nokugqwala phezu ophucuziwe metal amathuluzi.

Ukuze ugweme "reddishnesses" kufanele banakekele okusezingeni eliphezulu impahla izinga: ukugwema umswakama kwalo ngokweqile, isikhathi ukuhlanza kusuka ukungcola nothuli. Lwenza eziningi ezinengilazi ukugqwala nemithi, engatholwa ezitolo yezimoto.

Kusho zokususa nokugqwala - isixazululo caustic ukuthi ancibilikisa inkinga noma iyiguqule ibe ifilimu zokuzivikela. Kubalulekile nokukhumbula ukuthi nganoma iyiphi indlela (okuzenzela noma esitolo) kuyinto enobuthi kakhulu ngesintu nangeplanethi kwensimbi. Kufanele ngokuqinile ulandele imithetho yokusetshenziswa nokuphepha izinyathelo zokugwema ukulimala isikhumba ebusweni metal.
