Uphuculo kwiTekhnoloji ye-Steel Anticorrosion Technology Khusela uKhuseleko kunye noBomi boThutho lwezoShishino
Kwi-petrochemical, ukunikezelwa kwamanzi kamasipala, kunye namacandelo okuthutha igesi yendalo, iipayipi zensimbi, njengezithuthi eziphambili zokuthutha, zihlala zijongene nemingeni emininzi, kubandakanywa ukubola komhlaba, ukuchithwa kweendaba, kunye ne-oxidation ye-atmospheric. Idatha ibonisa ukuba i-avareji yenkonzo yobomi bemibhobho yentsimbi engacocwanga ingaphantsi kweminyaka emihlanu, ngelixa elo lonyango oluqhelekileyo lwe-anticorrosion lunokwandiswa ukuya kwiminyaka engama-20. Ngokuphuculwa kwemizi-mveliso kunye neemfuneko eziphakamileyo zokukhuselwa kwendalo, itekhnoloji yentsimbi yokunqanda ukubola iye yavela ekukhuselweni kotyatyazo olulodwa ukuya kwinqanaba elitsha lokhuseleko lomjikelo wobomi oquka "ukuphuculwa kwezinto, ukuphuculwa kwenkqubo, kunye nokubeka iliso ngobukrelekrele."
Okwangoku, itekhnoloji yentsimbi yokunqanda ukubola kombhobho wentsimbi ibonelela ngoluhlu olwahlukeneyo lweenkqubo ezilungiselelwe iimeko ezithile zesicelo. Kwicandelo lemibhobho engcwatywayo, i-3PE (i-3-layer polyethylene coating) i-anti-corrosion coatings yisisombululo esikhethiweyo kwimibhobho ye-oyile kunye negesi yomgama omde ngenxa yokuchasana kakhulu noxinzelelo lomhlaba kunye nokuchithwa kwe-cathodic. Isakhiwo sabo esidibeneyo, esiquka isiseko se-epoxy powder, i-adhesive ephakathi, kunye ne-polyethylene yangaphandle, inika zombini i-corrosion kunye nokukhusela impembelelo. Kwimibhobho ye-asidi kunye ne-alkaline kwishishini lemichiza, iingubo ze-fluorocarbon kunye ne-plastic linening zibonelela ngeenzuzo. Eyangaphambili iphakamisa i-inertness yekhemikhali ye-fluororesins ukuxhathisa imidiya enobungozi kakhulu, ngelixa lo mva uhlukanisa ngokwasemzimbeni imidiya ehanjiswayo ukusuka kumbhobho wensimbi ngokwawo ngokufaka udonga lwangaphakathi kunye nezinto ezifana ne-polyethylene kunye ne-polytetrafluoroethylene. Ngaphaya koko, igalvanizing yediphu eshushu isetyenziswa ngokubanzi kwiindawo ezinobume obuthambileyo ezifana nonikezelo lwamanzi lukamasipala kunye neenkqubo zokuhambisa amanzi kunye nenkxaso yesakhiwo sentsimbi ngenxa yexabiso eliphantsi kunye nofakelo olufanelekileyo. Isenzo se-anodic yombingelelo we-zinc layer inika ukhuseleko lwe-electrochemical oluhlala ixesha elide kumbhobho wensimbi.
Ukuphuculwa kweteknoloji kunye nokuveliswa kwezinto ezintsha kuqhuba ukuphuculwa komgangatho wepayipi yensimbi yokuchasana nokubola. Iinkqubo zemveli zokupeyinta ngesandla, ngenxa yemiba efana nobungqingqwa obungalinganiyo kunye nokuncamathela okungalunganga, ngokuthe ngcembe kuthatyathelwa indawo yimigca yemveliso ezenzekelayo. Ukutshiza okukhoyo ngoku kwe-electrostatic okuqhelekileyo kunye nobuchwepheshe bokutshiza okungenamoya bunokufikelela ukunyamezela ukutyeba ngaphakathi kwe ±5%. Kwintsimi yezinto ezichasene ne-corrosion, i-epoxy-friendly-friendly-based epoxy coatings kunye negraphene-modified anti-corrosion coatings ngokuthe ngcembe ithatha indawo ye-solvent-based based coatings, inciphisa ukukhutshwa kwe-VOC ngelixa iphucula ukuxhathisa kwemozulu kunye nokumelana nokunxiba. Ngelo xesha, iindlela zokubeka iliso ezihlakaniphile ziqala ukuhlanganiswa kwiinkqubo zokulwa ne-corrosion. Imibhobho yentsimbi kwezinye iiprojekthi eziphambili ngoku ixhotyiswe ngeenzwa zokubola. Ezi zivamvo ziqokelela imiqondiso yomonakalo wexesha lokwenyani kunye nomonakalo ogqunywe kudonga olungaphandle lombhobho, nto leyo evumela isilumkiso sangethuba somngcipheko wokungaphumeleli komhlwa kunye nolungiso oluchanekileyo.
Kwiiprojekthi zetsimbi zokunqanda ukubola, isivumelwano soshishino kukuba "izinto ezingama-30%, ukwakhiwa kwe-70%. Ngaphambi kokwakhiwa, umphezulu wombhobho wensimbi kufuneka uhlanjululwe ngesanti ukuze ususe umhlwa kwaye uqinisekise uburhabaxa bomhlaba we-Sa2.5 okanye ngaphezulu. Olu nyango lukwasusa ukungcola okunje ngeoyile, isikali, kunye nobunye ukungcola, luvula indlela yokuncamathelisa. Ngexesha lokwakha, ubukhulu bokwambathisa, ubushushu bokunyanga, kunye nexesha kufuneka kulawulwe ngokungqongqo ukuthintela iziphene ezinje ngemingxuma yokugquma kunye nokuvuza kokugquma. Emva kokugqitywa, ukusebenza kwe-anti-corrosion kufuneka kuqinisekiswe ngeendlela ezifana novavanyo lwentlantsi kunye novavanyo lokubambelela. Kuphela ngokuseka inkqubo ebanzi, evaliweyo equka "ukukhethwa kwezinto eziphathekayo - unyango lwangaphezulu - ulawulo lolwakhiwo kunye nokulawula - emva kokugcinwa" kunokubaluleka kwexesha elide lombhobho wensimbi wokuchasana nokubola.
Ngokuqhubela phambili kweenjongo "zekhabhoni ezimbini" kunye nokunyuka kweemfuno zokhuseleko lwamashishini, iteknoloji yombhobho wensimbi echasene nokubola iya kuqhubeka iguqukela kwindlela eluhlaza, esebenzayo, kunye neendlela ezikrelekrele. Kwixesha elizayo, izinto ezintsha ezichasene ne-corrosion ezidibanisa iipropati zekhabhoni ephantsi kunye nokukhuselwa kwexesha elide, kunye neenkqubo zokubeka iliso ezichasene ne-corrosion ezidibanisa iteknoloji yamawele edijithali, iya kuba yinto ephambili yophando lweshishini kunye nophuhliso oluphambili. Ezi ziza kubonelela ngekhaka eliluqilima lokhuseleko kwimibhobho eyahlukeneyo yemizi-mveliso kwaye zibe negalelo ekusebenzeni okukumgangatho ophezulu weziseko ezingundoqo.
