Uyazi ukuthi yiziphi izindlela zokwelashwa kwepuleti lensimbi eligqwalile?

Ipuleti lensimbifuthi kulula ngokwedlulele ukugqwala ngemva kwesikhathi eside, hhayi kuphela kuthinta ubuhle, kodwa futhi kuthinta intengo plate steel. Ikakhulukazi ukwenza laser phezu izidingo plate surface ziqinile impela, inqobo nje uma kukhona amabala nokugqwala ayikwazi ukukhiqizwa, icala imimese ephukile, ipuleti surface akulula flat ukushaya ikhanda laser cutting. Ngakho-ke yini okufanele siyenze ngepuleti lensimbi eligqwalile?

1. Ukwehliswa kwesandla kwasekuqaleni
Lokhu okubizwa ngokuthi i-primitive descaling ukuboleka abasebenzi ukuze behlise izinga mathupha. Lena inqubo ende futhi enzima. Nakuba inqubo ingasetshenziswa kufosholo, isando sesandla namanye amathuluzi, kodwa umphumela wokususwa kokugqwala awulungile ngempela. Ngaphandle kwalapho ukususwa kokugqwala kwendawo encane futhi kungekho ezinye izinketho zokusebenzisa le ndlela, ezinye izimo azinconywa.

2. Ukususwa kokugqwala kwethuluzi lamandla
Ukwehliswa kwethuluzi lamandla kubhekisela ekusetshenzisweni komoya ocindezelwe noma ukusetshenziswa kwezindlela eziqhutshwa amandla kagesi, ukuze ithuluzi lokwehlisa izinga likhiqize ukunyakaza okuyisiyingi noma okuhambisanayo. Lapho uthintana nobuso bepuleti yensimbi, sebenzisa ukungqubuzana nomthelela wayo ukuze ususe ukugqwala, isikhumba esine-oxidized nokunye. Ukwehliswa kwekhwalithi kanye nekhwalithi yethuluzi lamandla kuyindlela evame ukusetshenziswa yokwehlisa kumaphrojekthi okudweba ajwayelekile okwamanje.

Uma uhlangabezana nesimo sezulu esinemvula, sineqhwa, sinenkungu noma esiswakeme, ingaphezulu lensimbi kufanele limbozwe nge-primer ukuvimbela ukugqwala ukubuya. Uma ukugqwala kubuyile ngaphambi kokuthi kusetshenziswe i-primer, ukugqwala kufanele kususwe futhi futhi i-primer kufanele isetshenziswe ngesikhathi.
3. Ukususwa kokugqwala ngokuqhumisa
I-Jet descaling ibhekisela ekusetshenzisweni kwesikhungo se-impeller yomshini wejethi ukuhogela ukuhuzuka kanye nesihloko seblade ukuze kukhishwe i-abrasive ukuze kuzuzwe umthelela wesivinini esikhulu kanye nokwandisa ukungqubuzana ukuze kwenziwe ukwehla kwepuleti lensimbi.

4. Futha ukwehlisa
I-spray descaling method iwukusetshenziswa komoya ocindezelwe izoba incithakalo ngokuzungezisa ngesivinini esifuthwe ebusweni bepuleti lensimbi, futhi ngomthelela we-abrasive nokungqubuzana ukuze kukhishwe isikhumba se-oxide, ukugqwala nokungcola, ukuze ingaphezulu lepuleti lensimbi. ukuthola izinga elithile lokumahhadla, kuyasiza ekuthuthukiseni ukunamathela kwefilimu kapende.

5. Ukwehliswa kwamakhemikhali
Ukwehliswa kwamakhemikhali kungabuye kubizwe ngokuthi i- pickling descaling. Ngokusebenzisa isixazululo se-pickling ekuphenduleni kwe-asidi ne-metal oxides, chaza ama-oxide ensimbi, ukuze ususe i-oxide ebusweni bensimbi nokugqwala.

Kunezindlela ezimbili ezijwayelekile zokukhetha: ukukhetha okujwayelekile kanye nokukhetha okuphelele. Ngemuva kokukhetha, kulula ukucwiliswa emoyeni, futhi kufanele kudluliswe ukuze kuthuthukiswe ukumelana nokugqwala.

Ukwelashwa kwe-passivation kubhekisela epuleti lensimbi ngemva kokuchotshozwa, ukuze kunwetshwe isikhathi salo emuva kokugqwala, indlela esetshenziselwa ukwakha ifilimu evikelayo ebusweni bensimbi, ukuze kuthuthukiswe ukusebenza kwayo kokugqwala.

Ngokwezimo ezithile zokwakha, izindlela zokwelashwa ezihlukene zingasetshenziswa. Ngokuvamile ipuleti lensimbi kufanele ligezwe ngamanzi ashisayo ukuze lingathathi hlangothi ngokushesha ngemva kokukhetha, bese liyadlula. Ngaphezu kwalokho, insimbi ingabuye ihlanzwe ngamanzi ngokushesha ngemva kokukhetha, bese wengeza isixazululo esingu-5% se-sodium carbonate ukuze unciphise isisombululo se-alkaline ngamanzi, futhi ekugcineni ukwelashwa kwe-passivation.

6. Ukwehla komlilo
Ukwehla komlilo wepuleti lensimbi kubhekisela ekusetshenzisweni kwebhulashi lentambo yensimbi ukususa ukugqwala okunamathiselwe ngaphezulu kwepuleti lensimbi ngemva kokushisisa ngemva kokushisisa ilangabi. Ngaphambi kokukhipha ukugqwala ebusweni bepuleti lensimbi, isendlalelo sokugqwala esijiyile esinamathiselwe ngaphezulu kwepuleti lensimbi kufanele sisuswe ngaphambi kokukhipha ukugqwala ngokushisisa ilangabi.
