Irhasi yendalo ngamandla acocekileyo, asebenzayo, aluncedo, akumgangatho ophezulu kunye neekhemikhali.Ukuxhatshazwa kunye nokusetyenziswa kwayo kuneenzuzo ezibalulekileyo kwezoqoqosho, ezentlalo kunye nokusingqongileyo.Ngophuhliso olongezelelweyo lwerhasi yendalo yaseTshayina, ishishini legesi yendalo liza kujongana namathuba amatsha, likwajongene nemingeni emitsha.Ukuguqulwa komnatha wombhobho wokuqala okanye ukubeka umnatha omtsha wombhobho kufuneka kugxininise ukhuseleko, ukuphelisa yonke ingozi.Njengoko kunokubonwa kuthungelwano lwemibhobho ekhaya nakwamanye amazwe, unobangela wengozi, ebangelwe ziingozi ezitshabalalisayo zomntu zibangele umonakalo wokonakala kwemibhobho (kubandakanywa nokuqhekeka kwe-corrosion yoxinzelelo) kwindawo yesibini.Ezi zamva zihlala kunzima ukuzibona, zihlala zingahoywa, ukubola kwemibhobho ngokungathandabuzekiyo i-ajenda ebalulekileyo kufuneka ikhankanywe.

Ukusetyenziswa kwe-anticorrosion ephezulu yokugquma
Ezona ndlela ziphambili zombhobho werhasi yendalo ephantsi komhlaba wasekhaya nezamazwe ngamazwe zifanelekile ngokusekwe kumbhobho womhlaba wejografi, ubume bendawo, iimeko zejoloji, ukhuselo olongezelelwa lukhuseleko lwecathodic.Ipeyinti esetyenzisiweyo: i-petroleum asphalt, i-enamel yetar yamalahle, ipeyinti ye-epoxy.Umbhobho ongcwatywe wasekhaya wokunqanda ukubola osetyenziswa ngokuqhelekileyo ipeyinti yeasphalt yepetroleum.Ukuba indalo esingqongileyo yomhlaba, imicrobial, akukho siphazamiso sinzima kwizityalo ezimiliselwe nzulu, zithathwa njengomaleko ofikelelekayo wokunqanda umhlwa.Iimpawu zayo zokuhamba azifanelekanga kwindawo yokushisa okuphezulu kunye nokungcola okunzulu kwendawo ngexesha lokwakha, ukusetyenziswa kwayo kubonise ukuhla.Ngokwembono yehlabathi, eyona isetyenziswa kakhulu xa i-enamel yetar yamalahle kunye nepeyinti ye-epoxy.Eyangaphambili inomhlwa owomeleleyo wokuchasana nentsholongwane, ukungena kwengcambu echasene nesityalo, ukufunxwa kwamanzi aphantsi, ukuxhathisa kwi-cathodic delamination, iqhina elisongelwe ngokuqinileyo eludongeni, kukho iingenelo ezicacileyo zokusetyenziswa kumbhobho weoyile negesi eUnited States, eRussia. , kusetyenziso olukhulu.

Umbhobho wokwaleka umphezulu womgangatho wangaphambili uphuculo lwenkqubo yonyango
Umgangatho wogcino uxhomekeke kwinqanaba lokukhetha indlela yonyango lwangaphambili.Umhlwa othotywayo wesintu Umthetho wexesha kunye nongcoliseko lwabasebenzi kunzima ukuqinisekisa umgangatho.Kwiminyaka yakutshanje utyekelo lokusebenzisa ubushushu obuphezulu bomthetho wokuthomalalisa, umbhobho olayishwa kwiziko ngokukodwa kwi-350 ~ 400 ℃ eyongezwa ngokungena komoya, ukugqunywa kwe-3 ~ 4 h, isiqinisekiso esitshisiweyo se-oyile sinciphisa umgangatho.Oomatshini bokuchama endaweni yendlela yemveli yokuchola.Le ndlela kukusetyenziswa komoya ocinezelweyo ukuthwala intsimbi yokudubula (okanye isanti) ukwenza ukuhamba ngesantya esiphezulu sothutho impembelelo enamandla kumphezulu wentsimbi ngokusebenzisa umbhobho wompu ukususa ioli okanye i-oxide.Iyagqwala ngokupheleleyo, kodwa ikwaphucula uburhabaxa bomphezulu, ukonyusa indawo yonxibelelwano eludongeni kunye nokwaleka (malunga namaxesha angama-20), kunye nokuphucula ukomelela kwebhondi yokugquma, kunokuthintelwa ngokufanelekileyo ukudelela okunzulu.
