Rust weplishi: Ukukhetha, isicelo

Rust - i "sifo" oqhelekileyo zesinyithi. Ezi ngezinto ezomeleleyo ezahlukahlukeneyo abasingqongileyo. Zisetyenziswa ukudala zombane ekhaya, iimoto, izithuthi emoyeni, yaye kakhulu ngakumbi. Zonke uthimbo inamandla nazo ezenziwe ngentsimbi. Kodwa nantsi ingxaki: ngokuhamba kwexesha, abaninzi kubo sengozini igcwala - umhlwa. Material ibhuqiwe phantsi kwempembelelo kokusingqongileyo, kwaye uyilo iqala maxongo. Indlela lokusindisa metal ekufeni ethile? Yintoni weplishi umhlwa ukukhetha? Makhe sihlolisise kweli nqaku.

Ukususwa yongcoliseko ukukhanya

I ekuqaleni umhlwa, kungenza kube lula kakhulu ukuba bajongane nayo. Ukuba umonakalo ayikho nzulu kakhulu kulo velos metal ezaneleyo ukubhenela indlela ngoomatshini wokucoca. Ukuze wenze oku, ungenza baphathe komhlaba kunye ibrashi intamo. Sanding ususa ubumdaka maleko ndinihlangule metal ezivela andise "usulelo."

Kufuneka kuqatshelwe ukuba afune unyango ngomatshini isicelo yokulwa nomhlwa endleleni yakho phambi kokuba isicelo imichiza ukuze kufikelelwe isiphumo engcono. Ungahlela sandpaper enkulu njenge ibrashi abantamo.

Avtoochistitel

Good umhlwa weplishi - cleaner metal imoto. Esi sixhobo iyafumaneka: oko sithengwe na ezikhethekileyo lweemveliso evenkileni iimoto. Phambi kokuba isicelo kucetyiswa ukuba ukucoca umgangatho kunye ngebrashi intamo, bachatshazelwa yi irusi. Emva koko mmandla isale bengabameli-5 eemilimitha zamafu, aze avunyelwe ukuba eme nje imizuzu embalwa. Ke iintsalela ukuba zihlanjwe kwaye umphezulu eyomileyo ukoma. Ukuba mhlwa ke akaphumanga ngokupheleleyo, phinda le nkqubo.

Kufuneka kukhunjulwe ukuba nayiphi weplishi irusi ityhefu. le lingenwe asidi ebangela komtshiso isikhumba ungalindela. Sebenza kuyimfuneko ukuba banxibe iiglavu zokuzikhusela, izibuko kunye baphefumla. Ngaphezu koko, oko kuya kuba akufuneki ukufunda ngenyameko imiyalelo ukusetyenziswa kunye amanyathelo okhuseleko.

isisombululo zokwexeshana

Ngenxa yoko, amalinge abantu wadala ezininzi 'ikhaya "zokupheka for kokususa irusi. Bona zisekelwe izinto ezinyibilikayo oxide intsimbi kwakheka kwi kumphezulu metal liyatshabalala. Ekhaya ulwelo irusi weplishi lunghiselela iresiphi ilandelayo:

• amanzi - 300 ml;
• Ammonium - 50 g;
• 40% formalin - 250 g;
• abuhlungu soda okanye sodium hayidroksayidi - 50 g

Ukuxuba izinto, kufuneka exutywe kunye ilitha yamanzi. Isisombululo yafakwa izinto yesinyithi, ezo phantsi umhlwa (arhente unyango abaleka phezu komhlaba aza kusebenza). Shiya imizuzu eyi 15-40, ebukele amaxesha inkqubo. Susa amalungu ngoko nangoko emva yokuduka irusi. Ke ndakuhlamba kakuhle ngamanzi ashushu owomileyo ukoma. ukubonakala Original kunye ebuntsimbi ayenechaphothi zendalo alunakuqinisekiswa.

Acid nxamnye okona

Yinto eyaziwayo ukuba asidi bayakwazi ukunyibilikisa iikhompawundi ezininzi chemical. Le oxide yentsimbi hydrated kungekho ngaphandle. Kuba zokuhlanjululwa qualitative kufuneka babhenele asidi bomelele, yothiwani na zehydrochloric, sulphuric, kunye phosphoric. Noko ke, ukusebenzisa isisombululo uhlambulukile ayikho; they are kakhulu apile. Acid umsebenzi irusi ngokufanelekileyo, ukuba sithe saphinda inhibitor - into leyo ehla yokusabela imichiza. Enye kakhulu efikeleleka kakhulu methenamine.

Iresiphi ilula: kuyimfuneko ukuthatha nayiphi na asidi ezichazwe yaze yangxenga ifuthe lomanyano ngamanzi ukwenza% solution 5. Emva koko faka inhibitor nganye 0.5 grams ilitha bolwelo nganye. Umphezulu iphathwa ukufumana imali nilishiye libe okwethutyana. lula lo msebenzi ukumelana zehydrochloric, sulphuric okanye phosphoric acid. Apho ukuthenga ngumqobo? Ukuba emarikeni kunye ezivenkileni ezobuchwepheshe musa, sebenzisa le ndlela:

• iincopho zamazambane zisala ilitha ezintathu-ingqayi (kufuneka agcwalise isiqingatha umthamo wayo);
• kugalela acid yokugubungela neziqu;
• imizuzu 20 ngenkuthalo aziphazamise imixholo;
• amanzi ulwelo - Isicoci intsimbi kunye ukulungele.

Kuthethwa phosphoric acid

A solution, wenza kwisiseko phosphoric acid, adala irusi ngendlela kuluncedo kakhulu. Iindlela uguqula umhlwa ixesha elide nokwaleka umaleko. Ngeliphi ingqondo kufuneka phosphoric acid? Apho ukuze bathenge le mveliso? Fumana asidi, kuquka phosphoric acid, unokuba ezivenkileni okanye amasebe kwimizi-chemistry. Ukuze alungiselele isisombululo esebenzayo, iguqulela oxide intsimbi hydrated kwi ukutyabeka eziqinileyo zesinyithi, kucetyiswa ukuba usebenzise i-15% okanye 30% zolwelo isisombululo acid orthophosphoric. I-arhente ngenxa lisetyenziswa yi ibrashi okanye zokutshiza gun aze avunyelwe ukuba yome nko.

Enye indlela ephumelelayo yokulwa "ryzhinoy" ngokusekelwe orthophosphoric acid kuyinto iresipi:

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

Kutheni phosphoric acid luchaphazela ngoko umhlwa? lula Bonke zichazwe ngokwemigaqo chemistry: kuyo iguqula oxide intsimbi kwi phosphate, enza uhlobo ifilim phezu metal elikhusela kuyo.

Ezinye iindlela amanye amachiza

Ziziphi ezinye izinto ziya kukwazi ukuqalisa ngempumelelo ezirusayo? Mhlawumbi iindlela ezininzi ezilula izixhobo ezifana:

• iparafini ulwelo (okanye ulwelo petrolatum), kunye lactic acid kwi ratio 2: 1;
• iqhawulwa 100 ml yamanzi, zinc chloride (5 g) kunye cream lwethathari (0.5 g);
• turpentine okanye kerosine ukuya umhlwa okungenamsebenzi.

Zonke ezi ndlela izinto ezilungileyo kokususa umhlwa ngoomatshini metal kunye neminye imiba "non-zasekhaya" metal. Ngokuba ukusetyenziswa ekhaya, kukho iindlela ezininzi ilula nefikelelekayo yokususa uqweqwe ginger:

• fish oil - lisetyenziswa nomhlwa ze uyishiye okwethutyana;
• umxube of citric acid kunye neviniga kusenziwa ngokwemilinganiselo ngokulinganayo ukuphelisa le umhlwa kwigumbi lokuhlambela kunye nomhlwa amabala impahla, indlela isicelo sesibonelelo imizuzu engama-20 emva koko nyulu kunye isiponji nzima;
• of ukubhaka soda ukwenza oluludaka (ngokudibanisa kunye namanzi) kunye isicelo kumphezulu metal, eshiya ngokuba kuza ilixa, ngoko uhlambe;
• isisombululo of oxalic acid: 6 TSP .. iqhawulwa ml 300 zamanzi, nkxu kweziphumo ulwelo izinto ngumhlwa kangangesiqingatha seyure;
• asele "Coca-Cola" ukhona umhlwa ngenxa okuqulethwe phosphoric acid.

iindlela zokuthintela

Ukususa umhlwa ensimbi - elide hayi inkqubo elula. Nokumelana zinakho ukuthintelwa ngokusebenzisa ezinye iindlela ekhusela komhlaba ukusuka umonakalo. Nantsi imizekelo embalwa yendlela iiresiphi luncedo, ukunqanda ukwakheka umhlwa:

• iparafini okanye wax (20 g) kwaye zixutywe benzene (40 ml) kunye isisombululo nto - indlela ebalaseleyo zokuzikhusela izixhobo umhlwa ukuchwela;
• wax okanye iparafini (10 g) kunye separafini (30 ml) ukuthintela kokuvela umhlwa ngezixhobo metal olukhazimlisiweyo.

Ukuze uphephe "reddishnesses" kufuneka uthathe unonophelo kwezinto kwizinga eliphezulu Imfono: kuphephe ukufuma yayo kakhulu, ixesha ukucoca ukusuka ukungcola nothuli. It wadala a lot of Ipeyinti emelana nokudliwa ngumhlwa, nto leyo enokufunyanwa kwiivenkile ngomatshini.

Indlela yokususa umhlwa - isisombululo abuhlungu enyibilikayo ingxaki okanye iyiguqule ibe olukhuselayo umboniso. Kubalulekile ukukhumbula ukuba ndingade (ekhaya okanye ivenkile) yityhefu kakhulu ngabantu kunye netyhidiweyo. Kufuneka balandele ngqo imigaqo ukusetyenziswa kunye amanyathelo okhuseleko ukuphepha umonakalo isikhumba kunye umphezulu metal.
