Ukugqwala Nokuvikelwa Kwensimbi Yesiteshi

Ukugqwala Nokuvikelwa Kwensimbi Yesiteshi

Insimbi yeshaneli iyinsimbi ewumugqa omude onesiqephu esiphambanayo esimise okwe-groove, okuyingxenye yensimbi ye-carbon structural yokwakha nemishini. Kuyinsimbi yengxenye eyinkimbinkimbi ene-groove emise okwesiphambano. Insimbi yesiteshi isetshenziswa kakhulu ekwakheni izakhiwo, ukukhiqizwa kwezimoto, nezinye izakhiwo zezimboni, futhi ivame ukusetshenziswa ngokubambisana ne-I-imishayo. Ngenxa yesakhiwo sayo esikhethekile se-metallographic kanye nefilimu yokudlulisa amehlo, insimbi yesiteshi ngokuvamile ilukhuni ukubhekana nokusabela kwamakhemikhali phakathi nendawo bese igqwala, kodwa ayikwazi ukugqwala ngaphansi kwanoma yiziphi izimo. Ngesikhathi sokusetshenziswa kwensimbi yesiteshi, kungase kuhlangatshezwane nezinkinga ezihlukahlukene, futhi ukugqwala kungenye yezindaba ezibaluleke kakhulu. Ukugqwala kwensimbi yesiteshi ngokuvamile kubangelwa yizizathu ezimbili ezilandelayo.

1. Ukugqwala kwamakhemikhali: Amabala kawoyela, uthuli, ama-asidi, ama-alkali, usawoti, njll. anamathiselwe ebusweni bensimbi yesiteshi aguqulwa abe imidiya egqwalayo ngaphansi kwezimo ezithile, futhi asabela ngamakhemikhali ngezingxenye ezithile zensimbi yesiteshi, okuholela ekugqwaleni kwamakhemikhali kanye nokugqwala. ukugqwala; Ukuklwebheka okuhlukahlukene kungalimaza ifilimu ye-passivation, kunciphise amandla okuvikela ensimbi yesiteshi, futhi kusabela kalula ngemidiya yamakhemikhali, okuholela ekugqwaleni kwamakhemikhali nokugqwala.

2. Ukugqwala kwe-electrochemical: Ukuklwebheka okubangelwa ukuthintana nezingxenye zensimbi ye-carbon kanye nokwakheka kwebhethri eliyinhloko elinemidiya egqwalayo, okuholela ekugqwaleni kwe-electrochemical; Ukunamathela kwezinto ezivame ukugqwala njengokusika kwe-slag nokuchaphaza endaweni ebolayo kwakha ibhethri eliyinhloko, okuholela ekugqwaleni kwe-electrochemical; Amaphutha angokomzimba (ama-undercuts, ama-pores, imifantu, ukuntuleka kokuhlangana, ukuntuleka kokungena, njll.) kanye nokukhubazeka kwamakhemikhali (izinhlamvu ezimahhadla, ukuhlukaniswa, njll.) endaweni yokushisela kwakha ibhethri eliyinhloko eline-corrosion medium, okuholela ekugqwaleni kwe-electrochemical corrosion. .

Ngakho-ke, zonke izinyathelo ezisebenzayo kufanele zithathwe ngesikhathi sokucutshungulwa kwensimbi yesiteshi ukuze kugwenywe ukuvela kwezimo zokugqwala kanye nokugqugquzela ngangokunokwenzeka. Enye indlela ukusebenzisa i-aluminium spray coating. Ukufafaza ukunamathela kwe-aluminium kanye nokuvala nge-anti-corrosion coating kungandisa kakhulu impilo yesevisi ye-coating. Kusukela emiphumeleni yesicelo se-theoretical kanye nesebenzayo, izigqoko ezifuthwe nge-zinc noma i-aluminium ziwungqimba olufanele olungezansi lwezingubo zokulwa nokubola; I-aluminium spray coating inamandla okubopha okuqinile ne-substrate yensimbi, impilo ende yokugqoka, kanye nezinzuzo ezinhle zezomnotho zesikhathi eside; Inqubo yokumboza i-aluminium spray iyaguquguquka futhi ifanele ukuvikelwa kwesikhathi eside kwezakhiwo zensimbi ezibalulekile ezinkulu nezinzima, futhi ingasetshenziswa esizeni.

Enye indlela iwukusebenzisa ukuvikela okunqanda ukugqwala okunathayela: insimbi yamashaneli ediphu eshisayo ingahlukaniswa ibe insimbi yamashaneli ashisayo ediphu kanye nensimbi yamashaneli ephephethwa ngokushisayo ngokuya ngezinqubo ezihlukene zokufaka uthayela. Ngemuva kokususwa kokugqwala, izingxenye zensimbi zicwiliswa kusisombululo se-zinc esincibilikisiwe cishe ku-440-460 ℃ ukuze kunamathisele ungqimba lwezinc ebusweni bezingxenye zensimbi, ngaleyo ndlela kufezeke inhloso yokulwa nokugqwala. Emkhathini ojwayelekile, ungqimba oluncane noluminyene lwe-zinc oxide lwakhiwa ebusweni bengqimba ye-zinc, okunzima ukuyincibilika emanzini ngakho-ke idlala indima ethile yokuvikela ensimbi yesiteshi.

I-Shandong Kungang Metal Technology Co., Ltd. igxile epayipini lensimbi nemikhiqizo yephrofayili, enenethiwekhi yokuthengisa ehlanganisa izifundazwe eziningi eChina nasemazweni amaningi aphesheya. Ngokusebenza kanzima kwazo zonke izisebenzi kanye nokubambisana okunobungane kwamayunithi odade, emkhakheni oguquguqukayo wemakethe yokujikeleza kwensimbi, singakwazi ukuqonda ngokunembile ulwazi namathuba, siqhubeke siqongelela futhi sithuthuke ngesivinini esisheshayo, futhi sizuze intuthuko nokukhula okuqhubekayo. Ngesevisi enhle kakhulu nemikhiqizo yekhwalithi ephezulu, sizuze ukwethenjwa ngamakhasimende ethu.
