Ngokwesiko, amaqhosha esinyithi abizwa ngokuba ngumhlwa okanye umhlwa ngenxa yokubola okanye ukubola okubangelwa yioksijini, ukufuma kunye nobunye ukungcola okusemoyeni.Emva kokuba iimveliso zetsimbi zabavelisi beqhosha leplastiki zigqwalile, ukukhanya kuya kuchaphazela umgangatho wokubonakala, kwaye izinto ezinzulu ziya kuchaphazela ukusetyenziswa kwaye zibangele ukuchithwa.Ngoko ke, iimveliso zetsimbi kufuneka zigcinwe ngokufanelekileyo ngexesha lokugcinwa, kwaye ingqalelo kufuneka ihlawulwe kwi-anti-rust.Iqhosha leGolide lobhedu
Izinto eziphambili ezibangela ukuba amaqhosha entsimbi aruse:
(1) Ukufuma okunxulumene neatmosfere Kwakwelo qondo lobushushu elifanayo, ipesenti yesiqulatho somphunga wamanzi okwiatmosfere kunye nesiqulatho sawo somphunga samanzi ozeleyo kuthiwa kukufuma okuzalanayo.Ngaphantsi komlinganiselo othile wokufuma, isantya sokubola kwesinyithi sincinci kakhulu, kodwa ngaphezu kolu mswakama olunxulumeneyo, izinga lokukhula linyuka kakhulu.Oku kufuma okunxulumeneyo kubizwa ngokuba kukufuma okubalulekileyo.Ukufuma okubalulekileyo kweentsimbi ezininzi kuphakathi kwe-50% kunye ne-80%, kwaye oko kwentsimbi malunga ne-75%.Ukufuma kwe-atmospheri ye-atmospheri kuneyona mpembelelo inkulu kwi-corrosion yesinyithi.Xa ukufuma kwe-atmospheric kuphezulu kunomswakama obalulekileyo, ifilimu yamanzi okanye amaconsi amanzi aya kuvela kumphezulu wesinyithi.Ukuba ukungcola okuyingozi okuqulethwe kwi-atmosphere kuchithwa kwifilimu yamanzi okanye amaconsi amanzi, kuya kuba yi-electrolyte, eya kwandisa ukubola.Iqhosha leGolide lobhedu
(2) Ubushushu bomoya kunye nokufuma Ubudlelwane phakathi kobushushu be-atmospheric kunye nokufuma kuchaphazela ukubola kwamaqhosha esinyithi.Oku kuneemeko eziphambili zilandelayo: okokuqala, umphunga wamanzi we-atmosfera uyanda ngokunyuka kwamaqondo obushushu;okwesibini, ubushushu obuphezulu bukhuthaza ukuqina kokubola, ngakumbi kwiindawo ezifumileyo, ubushushu obuphezulu, ukukhawuleza kwesantya sokutya.Xa ukufuma okunxulumeneyo kusezantsi, ifuthe leqondo lobushushu kwi-corrosion alibonakali, kodwa xa ukufuma okunxulumene noko kuphezulu kunobumanzi obubalulekileyo, ubungakanani bomhlwa buyanda ngokunyuka kwamaqondo obushushu.Ukongezelela, ukuba kukho ukuhluka kweqondo lokushisa phakathi kwe-atmosphere kunye nesinyithi, amanzi adibeneyo aya kubumba kwi-metal surface kunye nokushisa okuphantsi, okuya kubangela ukuba isinyithi sivuthe.Iqhosha leGolide lobhedu
(3) Iigesi ezitshabalalisayo zingcolisa iigesi ezityiwayo ezisemoyeni, yaye isulfur dioxide inempembelelo enkulu ekudlekeni kwesinyithi, ingakumbi kubhedu nakwizinto ezixutywe nalo.I-sulphur dioxide kwiatmosfera iphuma ikakhulu ekutshisweni kwamalahle.Ngexesha elifanayo, imveliso yokutsha i-carbon dioxide nayo inefuthe elibi.Iigesi ezonakalisayo zixutywa kumoya ojikeleze isityalo.Okufana ne-hydrogen sulfide, igesi ye-ammonia, igesi ye-hydrochloric acid, njl. zizinto zonke ezikhuthaza ukubola kwesinyithi.
4 kunye nezinto zomhlwa.Ngokomzekelo, i-chloride ithathwa ngokuba "lutshaba olufayo" lwezinyithi ezibolayo.Iqhosha leGolide lobhedu
