Amashubhu angenamthungo (SMLS)zisikwa zibe izingxenye ngezigayo zensimbi, bese zishiselwa esithandweni somlilo esine-perforated-perforated-size-straightening-cooling-cutting-cutting-packed ukuze sibe yimikhiqizo eqediwe efanelekayo, ngokuvamile engakwazi ukubekwa endaweni yokusebenzela yokukhiqiza yomsebenzisi. Njengoba kunezitoko eziningi kangaka, abathengisi badinga ukubeka ezinye izitoko. Kodwa-ke, abathengisi ngokuvamile abanazo izindawo zokugcina izimpahla zasendlini ezinkulu. Uma benza, izindleko ziphezulu kakhulu futhi azibizi. Eziningi zazo ziyizindawo zokugcina izimpahla ezingaphandle, futhi amashubhu ensimbi angenamthungo nakanjani azochayeka emoyeni naselangani uma ebekwe ngaphandle.

Okubizwa ngokuthi ukugqwala okuntantayo, njengoba negama lisho, ungqimba lokugqwala oluntanta phezu kwepayipi lensimbi elingenamthungo, elingasuswa ngethawula noma ezinye izinto. Kalula nje, ukugqwala okuntantayo kuthathwa njengokungekona ukugqwala, okungokwesimo esivamile. Ukugqwala kwamashubhu angenamthungo kuyisikhathi eside. Okungenani unyaka owodwa wamapayipi ensimbi angenamthungo achayeke emoyeni naselanga ngaphandle. Kunemigodi emikhulu nemincane ye-hemp kumashubhu ensimbi angenamthungo agqwalile. Umehluko owodwa omkhulu wokugqwala.

Ungabhekana kanjani ne-tube yensimbi engenamthungo?

1. Hlanza ngokuqondile
Uma kuwuthuli, uwoyela nezinye izinto, ama-solvents e-organic angasetshenziswa ukuhlanza ubuso bepayipi lensimbi engenamthungo. Kodwa lokhu kungasetshenziswa kuphela njengosizo kwezinye izindlela zokususa ukugqwala, futhi akukwazi ukususa ngokuqondile ukugqwala, isikali nezinye izinto endaweni yensimbi.

2. Ukukha
Ngokuvamile, izindlela ezimbili zokukhetha amakhemikhali kanye ne-electrolytic zisetshenziselwa ukwelashwa kokukhetha. Ukuhlanza ngamakhemikhali kungasusa isikali, ukugqwala, okokumboza amadala, futhi ngezinye izikhathi kungasetshenziswa njengendlela yokuhlehlisa ngemva kokuqhunyiswa kwesihlabathi nokususwa kokugqwala. Nakuba ukuhlanzwa kwamakhemikhali kungasusa ngempumelelo ukugqwala eshubhuni lensimbi engenamthungo futhi kwenze ingaphezulu lepayipi lensimbi lifinyelele izinga elithile lokuhlanzeka kanye nokuba mahhadlahhadla, iphethini yalo yehange elingashoni izodala ukungcoliswa okukhulu kwemvelo.

3. Ukupholisha nokugaya
Uma kunendawo enkulu yokugqwala, umkhiqizi we-Foundry angasebenzisa amathuluzi ochwepheshe ukuze asuse ukugqwala, futhi asebenzise izinto ezenziwe ngomshini ukupholisha kahle indawo yokugqwala. Ngaphezu kokuqeda izinto ezikhipha i-oxidizing, ingenza futhi ithubhu elingenamthungo lifinyelele endizeni ebushelelezi. Ngokuyinhloko sebenzisa amathuluzi afana namabhulashi ocingo ukuze upholishe ingaphezulu lamashubhu ensimbi angenamthungo, angasusa isikali esixegayo noma esiphakanyisiwe, ukugqwala, i-welding slag, njll. Ukususwa kokugqwala ngamathuluzi ezandla kungafinyelela izinga le-Sa2, futhi ukususwa kokugqwala kwethuluzi lamandla kungafinyelela. I-Sa3 level. Uma indawo engaphezulu yeshubhu yensimbi engenamthungo ixhunywe ngesilinganiso se-oxide esiqinile, umphumela wokususa ukugqwala wethuluzi awulungile, futhi ukujula kwephethini yehange okudingekayo ekwakhiweni kwe-anti-corrosion akukwazi ukufinyelelwa.

4. Futha (phonsa) isibhamu ukuze ususe ukugqwala
Ukufafaza (ukuphonsa) ukususwa kokugqwala kuqhutshwa injini enamandla amakhulu ukuze ijikelezise izindwani zokufafaza (ukuphonsa) ngesivinini esikhulu, ukuze isihlabathi sensimbi, izibhamu zensimbi, izingxenye zezintambo zensimbi, amaminerali kanye nezinye iziqhumane zifuthwe (ukujikijela) ngaphezulu. we-tube yensimbi ngaphansi kwesenzo samandla we-centrifugal, hhayi kuphela ukususa ngokuphelele ukugqwala, ama-oxides nokungcola, kodwa futhi ipayipi yensimbi engenamthungo ingafinyelela ukuqina komfaniswano odingekayo ngaphansi kwesenzo somthelela wobudlova kanye nokungqubuzana kwama-abrasives.

Noma iyiphi indlela yokukhipha ukugqwala ingase ibangele umonakalo omkhulu noma omncane kushubhu ye-carbon steel engenamthungo. Nakuba izindlela eziphumelelayo zokususa ukugqwala zingandisa impilo yesevisi yeamashubhu e-carbon steel, kungcono ukunaka ukugcinwa kwamashubhu angenasici kusukela ekuqaleni. Naka ukungena komoya, izinga lokushisa kanye nomswakama wendawo, futhi ulandele izindinganiso ezifanele zokugcina, ezinganciphisa kakhulu amathuba okugqwala epayipi lensimbi engenamthungo.
