Ubala njani izinga lokubola kwizinyithi?
Xa isinyithi sihlaziya okanye sihlahloka, asikwazi ukugcina imithwalo efanayo njengoko yenzayo ngaphambi kokubola kwe-corrosion. Kwinqanaba elithile, ukubola kungakhokelela kwiimeko eziyingozi.
Insimbi esetyenzisiweyo kwiibhuloji, izithuthi zomzila, kunye nezakhiwo zonke zixhomekeke kukubola. Ngenxa yoko, kubalulekile ukubeka iliso nokulawula ukubola ukuze kugweme ukuwa kwezakhiwo.
Iyini Intlawulo yoKhuseleko?
Isantya sokurhaxwa yisantya apho nasiphi na isinyithi esinikezelwayo sihlaselwa kwindawo ethile. Isantya, okanye isantya, kuxhomekeke kwiimeko zendalo kunye nohlobo, kunye nemeko, yesitye.
Iirhafu ze-Corrosion kwi-US ngokuqhelekileyo zibalwa ngokusebenzisa i-mpy (iMils ngonyaka). Ngamanye amazwi, izinga lokurhoxiswa lisekelwe kwinani lamithamitha (iwaka leesentimitha) lingena ngonyaka.
Ukuze ubale izinga lokubola, ulwazi olulandelayo lufanele luqokelelwe:
- Ukulahleka kwesisindo (ukwehla kwisisindo sesitya ngexesha lokubhekiswa kwexesha)
- Ubuninzi (ubuninzi bensimbi)
- Indawo (ingqonge indawo yokuqala yesalathisi)
- Ixesha (ubude bexesha lokubhaliweyo)
Iimithombo ze-Intanethi zokubala amaxabiso okuNyuka:
I-Corrosionsource.com inikeza i-calculator ye-metal corrosion rate rate calculator ye-computing rates of corrosion rates.
Ukusebenzisa i-calculator, landela ikhonkco apha: I-Corrosion Rate Calculator
Ingenisa nje iinkcukacha ezingentla kwaye nqakraza "Bala" ukubala amaxabiso okubola kwiimitha, amasentimitha, i-microns okanye iimithamitha ngonyaka, okanye ama-intshi ngomzuzu.
Ukuguqula iiRhafu zoKhuseleko:
Ukuguqula izinga lokurhoxisa phakathi kwama-milsi ngonyaka kwaye i-metric eyi-millimeter ngonyaka (mm / y), ungasebenzisa ukulingana okulandelayo:
1 mpy = 0.0254 mm / y = 25.4 microm / y
Ukubala izinga lokurhoxiswa kwelahleko yensimbi:
mm / y = 87.6 x (W / DAT)
apho:
W = ukulahlekelwa kwesisindo kwiimilligram
D = ubuninzi bensimbi kwi g / cm3
A = indawo yesampuli kwi-cm2
T = ixesha lokutshatyalaliswa kwesampuli yentsimbi kwieyure
Kutheni ukuxhatshazwa kweMali kuPhatha
Iirhafu zokurhoxiswa zibeka ixesha lokuphila kwezakhiwo zesebe. Oku kunyanzelisa ukhetho lwezinyithi ezisetyenziselwa iinjongo ezahlukeneyo, kwaye kwiindawo ezahlukeneyo. Kwakhona kugqiba iimfuno zokulondoloza izakhiwo: isakhiwo sesinyithi kwindawo emanzi ingadinga ukugcinwa rhoqo kunokuba isakhiwo esifanayo kwindawo ekhulayo. Iishedyuli zesondlo zenziwe ngokusekelwe kwiintlobo zokubala ezichazwe ngasentla.
Yintoni Ubunjineli Ubunjineli?
Ubunjineli bokuchithwa ngumoya ngumsebenzi omtsha ozinikele ekunciphiseni, ekuguquleni, nasekukhuseleni impembelelo yokubola kwizinto kunye nesakhiwo. Banoxanduva lokuphuhla izambatho kunye nezonyango ezingasetyenziselwa kwisinyithi ukuphucula ukutshatyalaliswa kwensimbi kwi-corrosion. Baye babandakanyeka nokuphuhliswa kwezixhobo ezingekho phantsi kokungcoliswa.
Ngokomzekelo, ngezinye iinkqubo iindawo ezinobungozi okanye ezibizayo, iinjineli zokurhoxisa zingancoma kwaye ziphumeze izisombululo.
