Ukonakala kunye noKhuseleko lweSiteshi seChannel

Intsimbi yomjelo yintsimbi ende ene-groove emilisekileyo ye-cross-section, eyeyentsimbi ye-carbon structural yokwakha kunye noomatshini. Yintsimbi yecandelo eliyinkimbinkimbi kunye ne-groove shaped cross-section. Intsimbi yentsimbi isetyenziselwa ikakhulu kwizakhiwo zokwakha, ukuveliswa kwezithuthi, kunye nezinye izakhiwo zoshishino, kwaye zihlala zisetyenziswa ngokubambisana ne-I-beams. Ngenxa yesakhiwo sayo esikhethekileyo semetallographic kunye nefilimu ye-surface passivation, intsimbi yeshaneli ngokuqhelekileyo inzima ukujamelana neekhemikhali kunye ne-medium kunye ne-corrod, kodwa ayinakugqwala phantsi kwayo nayiphi na imeko. Ngethuba lokusetyenziswa kwentsimbi yentsimbi, iingxaki ezahlukahlukeneyo zinokuthi zihlangabezane, kwaye ukubola ngenye yezinto ezibaluleke kakhulu. I-Corrosion yentsimbi yentsimbi ngokuqhelekileyo ibangelwa zezi zizathu zibini zilandelayo.

1. I-Chemical corrosion: I-oyile ye-oyile, uthuli, i-acids, i-alkalis, iityuwa, njl. njl ukurusa; Imikrwelo eyahlukeneyo inokonakalisa ifilimu yokudlula, inciphise amandla okukhusela entsimbi yesitishi, kwaye iphendule ngokulula ngemidiya yekhemikhali, okukhokelela kwi-corrosion yeekhemikhali kunye nokurusa.

2. I-Electrochemical corrosion: Imikrwelo ebangelwa ukudibana kunye neengxenye zetsimbi zekhabhoni kunye nokubunjwa kwebhetri ephambili kunye neendaba ezitshabalalisayo, okubangelwa ukubola kwe-electrochemical; Ukuncamatheliswa kwezinto ezithandwa ngumhlwa ezifana nokusikwa kwe-slag kunye nokutshiza kwindawo enomhlwa kwenza ibhetri yokuqala, ekhokelela ku-electrochemical corrosion; Iziphene zomzimba (i-undercuts, pores, cracks, ukungabikho kokudibanisa, ukungabikho kokungena, njl.) kunye neziphene zekhemikhali (iinkozo ezinqabileyo, ukuhlukana, njl.) .

Ngoko ke, onke amanyathelo asebenzayo kufuneka athathwe ngexesha lokucutshungulwa kwentsimbi yentsimbi ukuphepha ukwenzeka kweemeko zokubola kunye nokunyanzeliswa kangangoko kunokwenzeka. Enye indlela kukusebenzisa isitshizi se-aluminiyam. Ukutshiza i-aluminium yokugquma kunye nokutywinwa nge-anti-corrosion coating kunokwandisa kakhulu ubomi benkonzo yokugqoka. Ukususela kwiimpembelelo ze-theoretical kunye ne-practical application, i-zinc okanye i-aluminiyam yokutshiza i-coatings iyona mgangatho ophantsi we-anti-corrosion coatings; I-aluminium yokutshiza i-aluminiyam inamandla okubambisana okuqinileyo kunye ne-substrate yensimbi, ubomi obude bokugquma, kunye neenzuzo ezilungileyo zezoqoqosho zexesha elide; Inkqubo yokutshiza ye-aluminium iguquguqukayo kwaye ifanelekile ukukhuselwa kwexesha elide ezibalulekileyo kwaye kunzima ukugcina izakhiwo zetsimbi, kwaye zingasetyenziswa kwisiza.

Enye indlela kukusebenzisa ukhuseleko lwe-galvanized anti-corrosion: intsimbi eshushu yokudipha isinyithi ingahlulwa ibe yintsimbi eshushu yokuntywila kunye nentsimbi yombhobho evuthelweyo. Emva kokususwa komhlwa, iinxalenye zentsimbi zintywiliselwa kwisisombululo se-zinc esityhidiweyo malunga ne-440-460 ℃ ukuncamathisela i-zinc layer kumphezulu wezinto zentsimbi, ngaloo ndlela kufezekiswa injongo yokuchasana nokubola. Kwi-atmospheric jikelele, umgca omncinci kunye ne-dense ye-zinc oxide yenziwa phezu komgangatho we-zinc layer, okunzima ukuyichitha emanzini kwaye ngoko idlala indima ethile yokukhusela kwintsimbi yentsimbi.

I-Shandong Kungang Metal Technology Co., Ltd. igxile kwimibhobho yentsimbi kunye neemveliso zeprofayili, kunye nenethiwekhi yokuthengisa egubungela amaphondo amaninzi e-China kunye namazwe amaninzi angaphandle. Ngokusebenza nzima kwabo bonke abasebenzi kunye nentsebenziswano enobuhlobo yeeyunithi zoodade, kwintsimi eguquguqukayo yemarike yokujikeleza kwentsimbi, sinokuqonda ngokuchanekileyo ulwazi kunye namathuba, ngokuqhubekayo siqokelela kwaye siphucule ngokukhawuleza, kwaye sizuze uphuhliso oluqhubekayo kunye nokukhula. Ngenkonzo egqwesileyo kunye neemveliso ezikumgangatho ophezulu, siphumelele ukuthenjwa ngabathengi bethu.
