Kuye ngendlela yokusebenza, kunezindlela eziyisithupha eziyinhloko zokukhetha i-asidi kanye nokudlulisa insimbi engagqwali: indlela yokucwiliswa, indlela yokunamathisela, indlela yokuxubha, indlela yokufafaza, indlela yokusakaza, kanye nendlela ye-electrochemical.Phakathi kwalokhu, indlela yokucwilisa, indlela yokunamathisela, kanye nendlela yokufafaza ifaneleka kakhulu ekukhetheni i-asidi kanye nokuphasa amathangi nemishini yensimbi engagqwali.
Indlela Yokucwiliswa:Le ndlela ifaneleka kakhuluamapayipi ensimbi engagqwali, izindololwane, izingxenye ezincane, futhi inikeza umphumela wokwelapha ongcono kakhulu.Njengoba izingxenye eziphathwayo zingacwiliswa ngokugcwele kusisombululo se-acid pickling kanye ne-passivation, ukusabela kwendawo kuphelile, futhi ifilimu ye-passivation iminyene futhi ifana.Le ndlela ilungele ukusebenza kwenqwaba okuqhubekayo kodwa idinga ukugcwaliswa kabusha kwesixazululo esisha njengoba ukugxila kwesixazululo esisabelayo kuncipha.I-drawback yayo ukuthi inqunyelwe ukwakheka nomthamo wethangi le-asidi futhi ayifanele imishini emikhulu noma amapayipi anomumo omude ngokwedlulele noma obanzi.Uma ingasetshenziswa isikhathi eside, ukusebenza kahle kungase kwehle ngenxa yokuhwamuka kwesixazululo, okudinga indawo ezinikele, ithange le-asidi, nezinto zokushisisa.
Indlela yokunamathisela: I-acid pickling paste yensimbi engagqwali isetshenziswa kakhulu ekhaya futhi itholakala ochungechungeni lwemikhiqizo.Izingxenye zayo eziyinhloko zifaka i-nitric acid, i-hydrofluoric acid, i-corrosion inhibitors, nama-thickening agents, ngezilinganiso ezithile.Isetshenziswa ngesandla futhi ilungele ukwakhiwa endaweni.Kusebenza ekukhetheni nasekushintsheni amashisela ethangi lensimbi engagqwali, ukushintsha umbala ngemva kokushisela, iziqongo zedekhi, amakhona, ama-engeli afile, izitebhisi ezingemuva, nezindawo ezinkulu ezingaphakathi kwamakhompathi ewuketshezi.
Izinzuzo zendlela yokunamathisela yukuthi ayidingi imishini ekhethekile noma indawo, imishini yokushisa ayidingeki, ukusebenza kwendawo kuyaguquguquka, ukukhethwa kwe-asidi nokudlula kuqedwa ngesinyathelo esisodwa, futhi kuzimele.I-passivation paste inesikhathi eside seshelufu, futhi uhlelo ngalunye lusebenzisa unamathisele omusha wokusebenzisa isikhathi esisodwa.Ukusabela kuyama ngemva kongqimba olungaphezulu lwe-passivation, okwenza kungabi lula ukugqwala kakhulu.Ayinqunyelwe isikhathi sokuhlanza esilandelayo, futhi ukudlula ezindaweni ezibuthakathaka njengama-welds kungaqiniswa.Ububi buwukuthi indawo yokusebenza yomqhubi ingase ibe mpofu, umfutho wabasebenzi uphakeme, izindleko ziphakeme uma kuqhathaniswa, futhi umphumela wokwelapha odongeni lwangaphakathi lwamapayipi ensimbi engagqwali ungaphansi kancane, odinga inhlanganisela nezinye izindlela.
Indlela yokufafaza:Ifanele amasayithi angaguquki, izindawo ezivaliwe, imikhiqizo eyodwa, noma okokusebenza okunezakhiwo ezilula zangaphakathi zokucosha i-asidi nokudlula, njengenqubo yokufafaza yokukhetha emugqeni wokukhiqiza wensimbi.Izinzuzo zako wukusebenza okusheshayo okuqhubekayo, ukusebenza okulula, umthelela omncane wokugqwala kubasebenzi, futhi inqubo yokudlulisa ingafafaza ipayipi futhi nge-asidi.Inezinga eliphezulu lokusetshenziswa kwesixazululo.
