Iko kukanganisa kukuru paunenge uchikurudzira muviri wemotokari uri wega

Galvanization yemuviri wemotokari ndiyo inonyanya kushanda tekinoroji yekurwisa ngura, iyo inoita kuti zvikwanise kushandisa mota mumamiriro ezvinhu akashata pasina mhedzisiro. Ichokwadi, inodhura zvikuru. Hazvishamisi, saka, kuti varidzi vemotokari dzakashandiswa, kunyanya avo "vakatotumbuka", vanosarudza kuita nzira iyi pachavo. Asi kazhinji pasina kubudirira kukuru. Sei, uye sei kunyatsogadzira motokari kumba, iyo AvtoVzglyad portal yakafunga.

Nekugadzirisa muviri wega, mutyairi ane hanya anofarira kuvhara simbi isina chinhu nechimwe chinhu asati apenda. Uye sarudzo, sekutonga, inowira pa "chimwe chinhu chine zinc." Nekudaro, vanhu vashoma vanoziva kuti kune mashoma akakosha enziyo echokwadi galvanizing pamusika nhasi. Muzvitoro, muridzi wemotokari anowanzo tengeswa maprimers anofungidzirwa kuti zinc, uye inoshamisa inoshandura ngura kune zinc. Zvese izvi hazvinei nechekuita neku galvanizing chaiko.

MASHOKO AKASIYANA...

Saka, "bug" inoputika yengura yaonekwa pamotokari yako. Panyaya yemotokari dzakashandiswa, mamiriro acho anowanzoitika, kunyanya munzvimbo yezvikumbaridzo uye mavhiri mavhiri. Kazhinji nzvimbo idzi dzinongocheneswa kubva kune yakasununguka ngura, yakanyoroveswa neimwe mhando yekushandura, primer uye pendi inoiswa. Kwenguva yakati zvinhu zvose zvakanaka, uye ipapo ngura inobuda zvakare. Zvakadaro sei? Mushure mezvose, mukugadzirira vakashandisa shanduri-ku-zinc converter! At least ndozvazvinotaura pa label.

Muchokwadi, zvese zvakagadzirirwa zvakadaro zvinogadzirwa pahwaro hwe orthophosphoric acid uye iyo yakanyanya kuumbwa kwakadai inogona kuita phosphate pamusoro, uye iyi ichava porous phosphating, iyo ichaita ngura mune ramangwana. Iyo firimu inoguma haigone kushandiswa sechidziviriro chakazvimirira - chekupenda chete. Saizvozvo, kana pendi iri yemhando yakashata, kana kuti yakangopepetwa, iyi dhizaini haidzivirire kubva mukuora.

CHII CHEKUSARUDZA?

Pamasherufu ezvitoro zvedu pane zvakare nziyo dzechokwadi dzekuzvigadzika, uye kune marudzi maviri - echando galvanizing (iyi nzira inonziwo galvanizing) uye yegalvanic galvanizing (vanowanzo kuuya neese electrolyte uye anode), asi ivo vanodhura kurongeka kwehukuru hunodhura kupfuura vashanduri. Isu hatitore kutonhora galvanizing muaccount, iyo yakatanga kugadzirwa yekuputira simbi zvimiro, haina kugadzikana kune organic zvinonyungudutsa uye kukuvara kwemichina. Isu tinofarira nzira yegalvanic yekushandisa zinc, nepo zvese zvinodiwa pakuita izvi zvinogona kuitwa kumba. Saka, zvichazodiwa here kuitira kuti galvanize nzvimbo yemuviri?

Usati waenderera mberi, unofanirwa kuyeuka kuchengetedza zvidziviriro paunenge uchishanda nema reagents: shandisa mask yekufema, magirovhosi erabha, magirazi, uye ita manipulations ese kunze kana munzvimbo ine mhepo inofefetera.

ZVIMWE ZVIMWE MVURA INOFISA

Danho rekutanga. Kugadzirira kwesimbi. Nzvimbo yesimbi inofanira kunge isina zvachose ngura uye pendi. Zinc haina kuwira pa ngura, uye kunyanya papende. Isu tinoshandisa sandpaper kana yakakosha nozzles pane drill. Zviri nyore kubika chikamu chiduku mu 10% (100 gramu yeasidhi pa 900 ml yemvura) mhinduro ye citric acid kusvikira ngura yaparadzwa zvachose. Zvadaro degreisa pamusoro.

Danho repiri. Kugadzirira kwe electrolyte uye anode. Galvanic galvanizing maitiro ndeaya anotevera. Mumushonga we electrolyte (electrolyte inoshanda se conductor wechinhu), zinc anode (kureva, plus) inotamisa zinc kune cathode (kureva, minus). Kune akawanda eelectrolyte mabikirwo anotenderera pawebhu. Iyo iri nyore ndeye kushandisa hydrochloric acid, umo zinc inonyungudika.

Acid inogona kutengwa muchitoro chemakemikari reagent, kana muchitoro chehardware. Zinc - muchitoro chimwe chete chemakemikari, kana kutenga akajairwa mabhatiri emunyu uye bvisa kesi kubva kwavari - inogadzirwa ne zinc. Zinc inofanira kunyungudutswa kusvika yamira kuita. Muchiitiko ichi, gasi rinosunungurwa, saka kushandiswa kwose, tinodzokorora, kunofanira kuitwa mumugwagwa kana munzvimbo ine mhepo yakanaka.

Iyo electrolyte inoitwa zvakanyanya kuoma nenzira iyi - mu 62 milliliters emvura tinonyungudutsa 12 gramu ye zinc chloride, 23 gramu e potassium chloride uye 3 gramu ye boric acid. Kana yakawanda electrolyte ichidiwa, zvigadzirwa zvinofanira kuwedzerwa zvakaenzana. Zviri nyore kuwana reagents akadaro muchitoro chakakosha.

ZVINONONO UYE ZVINOSUKA

Danho rechitatu. Tine nzvimbo yakanyatsogadzirirwa - yakacheneswa uye yakasvibiswa simbi, anode muchimiro chezinc bhatiri kesi, electrolyte. Tinoputira anode nemucheka wekotoni, kana shinda yekotoni, kana gauze yakapetwa muzvikamu zvakawanda. Batanidza anode kune plus yebhatiri remota kuburikidza newaya yehurefu hwakakodzera, uye minus kumuviri wemotokari. Nyura shinda yedonje pane anode mu electrolyte kuitira kuti izere. Zvino, nekufamba zvishoma nezvishoma, tinotanga kutyaira nesimbi isina chinhu. Inofanira kunge iine grey kupera pairi.

PAKAKANISWA PAKUPI?

Kana iyo yekupfekedza yakasviba (uye nekudaro brittle uye porous), saka iwe unotyaira anode zvishoma nezvishoma, kana density iripo yakanyanya kukwirira (munyaya iyi, bvisa minus kubva mubhatiri), kana iyo electrolyte yaoma pabhatiri. shinda yekotoni. Mucheka wakapfava wegrey haufanire kukweshwa neminwe. Ukobvu hwekuputira huchafanirwa kugadziriswa neziso. Nenzira iyi, anosvika 15-20 µm machira anogona kuiswa. Mwero wekuparadzwa kwayo ungangoita 6 microns pagore pakubata nekunze kwezvakatipoteredza.

Muchiitiko chechikamu, inoda kugadzirira bhati (plastiki kana girazi) ne electrolyte. Maitiro acho akafanana - kuwedzera kune zinc anode, kubvisa kune yakasara chikamu. Iyo anode uye chikamu chinosara chinofanira kuiswa mu electrolyte kuitira kuti zvisabatane. Zvadaro ingotarisa kune zinc.

Mushure mekunge maisa zinc, zvakakosha kushambidza nzvimbo ye zincing zvakanaka nemvura kuti ubvise electrolyte yose. Hazvizove zvakanyanyisa kudzikisa pasi zvakare usati wapenda. Nenzira iyi, zvikamu kana basa remuviri rinogona kuwedzerwa hupenyu. Kunyangwe nekuparadzwa kwekunze kwepende uye primer, zinc haingakurumidzi kuita ngura simbi yakarapwa.
