Indlela yokulwa nokugqwala kwensimbi engagqwali

Igridi yensimbi engagqwali inezinzuzo zokuvikela imvelo, ukungapendeki, ukumelana nokugqwala, njll., ukunikeza abantu umbono omuhle "wokungagqwali, ukuhlanzeka, kanye nokuthungwa kwekhwalithi ephezulu". Ukuthungwa kwensimbi yensimbi engagqwali kuvumelana nobuhle besimanje futhi iye yasetshenziswa kabanzi kumaphrojekthi amaningi wokugawula insimbi ekhaya naphesheya. Kodwa-ke, ngemva kwezinqubo zokusika, ukuhlanganisa, ukushisela, njll ekukhiqizeni insimbi yensimbi, i-stainless steel grating ijwayele ukugqwala, futhi kwenzeka "ukugqwala kwensimbi engagqwali". Lesi sihloko sifinyeza amaphuzu okulawula kanye nezinyathelo zesixazululo okufanele ziqashelwe kusixhumanisi ngasinye segridi yensimbi engagqwali, futhi inikeza ireferensi yokugwema noma yokunciphisa ukugqwala nokugqwala kwegridi yensimbi engagqwali.

Izinyathelo zokuthuthukisa i-anti-corrosion
Ngokwezimbangela zokugqwala kwegridi yensimbi engagqwali, kuhlongozwa izindlela zokuthuthukisa ezihambisanayo kusixhumanisi ngasinye senqubo yokukhiqiza igridi yensimbi engagqwali ukuze kuncishiswe noma kugwenywe ukugqwala kwensimbi engagqwali.
3.1 Ukugqwala okubangelwa ukugcinwa okungafanele, ukuthuthwa nokuphakanyiswa
Ngokugqwala okubangelwa ukugcinwa okungalungile, izinyathelo ezilandelayo zokulwa nokugqwala zingathathwa: ukugcinwa kufanele kuhlukaniswe ngokuqhathaniswa kwezinye izindawo zokugcina izinto; kufanele kuthathwe izinyathelo zokuvikela ezisebenzayo ukuze kugcinwe ingaphezulu lensimbi engagqwali lihlanzekile ukuze kugwenywe uthuli, uwoyela, ukugqwala, njll. ekungcoliseni insimbi engagqwali futhi kubangele ukugqwala kwamakhemikhali.
Ngokugqwala okubangelwa ukuthutha okungalungile, izinyathelo ezilandelayo zokulwa nokugqwala zingathathwa: ama-racks akhethekile okugcina kufanele asetshenziswe ngesikhathi sokuthutha, njengama-racks okhuni, ama-carbon steel racks anezindawo ezipendiwe, noma ama-rubber pads; amathuluzi okuthutha (njengamatroli, izimoto zamabhethri, njll.) kufanele asetshenziswe ngesikhathi sokuthutha, futhi kuthathwe izinyathelo zokuzihlukanisa ezihlanzekile nezisebenzayo. Izinyathelo zokuzivikela: Ukudonsa akuvunyelwe ngokuphelele ukugwema amaqhubu nokuklwebheka.
Ngokugqwala okubangelwa ukuphakamisa okungafanele, lezi zinyathelo ezilandelayo zingathathwa: Amapuleti ensimbi engagqwali kufanele aphakanyiswe ngezinkomishi zokudonsa i-vacuum namathuluzi okuphakamisa akhethekile, njengamabhande okuphakamisa, ama-chucks akhethekile, njll. Gwema ukusebenzisa amathuluzi okuphakamisa insimbi nama-chucks; Akuvunyelwe ngokuphelele ukusebenzisa izintambo zocingo ukugwema ukunwaya indawo yensimbi engagqwali; Bamba ngokucophelela ukuze ugweme imihuzuko ebangelwa umthelela namaqhubu.
3.2 Ukugqwala okubangelwa ukukhethwa kwamathuluzi okungafanele kanye nokusebenzisa inqubo ngesikhathi sokukhiqiza
Ngokugqwala okubangelwa ukukhishwa kwenqubo ye-passivation engaphelele, izinyathelo ezilandelayo zokunqanda ukugqwala zingathathwa: Ngesikhathi sokuhlanza i-passivation, Sebenzisa iphepha lokuhlola i-pH ukuhlola izinsalela ze-passivation; Kukhethwa ukwelashwa kwe-electrochemical passivation.
Izinyathelo ezingenhla zingagwema insalela yezinto ezine-acidic kanye nesenzakalo sokugqwala kwamakhemikhali.
Ngokugqwala okubangelwa ukugaywa okungafanele kwama-welds nemibala ye-oxidation, izinyathelo ezilandelayo zokunqanda ukugqwala zingathathwa: ① Ngaphambi kokushisela i-weld, sebenzisa uketshezi olulwa nokuchaphaza ukuze unciphise ukunamathela kwe-spatter yokushisela; ② Sebenzisa ifosholo eliyisicaba lensimbi engagqwali ukuze ususe isipatha sokushisela kanye ne-slag; ③ Gwema ukunwaya isisekelo sensimbi engagqwali ngesikhathi sokusebenza futhi ugcine izinto eziyisisekelo zihlanzekile; gcina ukubukeka kuhlanzekile ngemva kokugaya nokuhlanza umbala we-oxidation ovuzayo ngemuva kwe-weld noma wenze ukwelashwa kwe-electrochemical passivation.
