1. Ukususwa kokugqwala kobuso beipayipi lensimbikufanele ifinyelele izinga le-sa2.5 le-gb8923-88, ebonisa umbala wemvelo wensimbi, ngaphandle kwamafutha abonakalayo, ukungcola, ukugqwala, nokunye okunamathiselwe.
2. Ungqimba olulwa nokugqwala kufanele lwelashwe phakathi namahora angu-24, lube nogqinsi olufanayo, luminyene, aluguquguquki, alunamibimbi, lungabi namgodi, aluvuzi umbala, lungabi nazandla ezinamathelayo, futhi lubonakale ngokuphelele.
3. Ukuqina okungaphezulu kwengqimba elwa nokugqwala kuhle, futhi ukumelana nokugqokwa kuhle, futhi ukumiswa kwentambo yocingo akukhiqizi amamaki angu-0.1mm.
4. Kulula ukuyisebenzisa, ayinangozi emzimbeni womuntu nendawo ezungezile.
5. Ngemuva kokuthi ungqimba lwe-anti-corrosion luphulukisiwe, sebenzisa ummese ukuze wenze i-incision efana nolimi, futhi isendlalelo sokumboza asikwazi ukukhishwa, futhi i-primer ihlanganiswe kahle endaweni yensimbi.
6. Izinto ezilwa nokugqwala kufanele zimelane ne-asidi, i-alkali, nokuhlasela kwamagciwane. Ipuleti lensimbi eligcotshwe ngezinto ezilwa nokugqwala kufanele licwiliswe ku-10% we-hydrochloric acid kanye nesixazululo esingu-10% se-caustic soda izinsuku ezingama-90 ngokulandelana; ecwiliswe kusixazululo se-sulfuric acid esingu-30% izinsuku ezingu-7, ungqimba lwepayipi lwensimbi olulwa nokugqwala Akukho shintsho ekubukekeni.
7. Ngemuva kokuthi i-anti-corrosion coating selashiwe futhi ezinyangeni ezintathu kamuva, ukusebenza kwe-insulation kuhle. I-voltage yokuwohloka etholwe yi-EDM idingeka ukuthi ifinyelele ku-10000v, ubuncane abukho ngaphansi kuka-6000v, futhi kushaywa izimbobo ezimbili kuphela ezingaphezu kuka-6000v ngemitha yesikwele ngayinye ezivunyelwe ukugqoka.
8. Uma usebenzisa i-epoxy coal tar pitch anti-corrosion paint, i-primer kufanele iqedwe kungakapheli ihora elilodwa ngemuva kokukhishwa kwesihlabathi nokugqwala, ngamafutha amahlanu nezindwangu ezimbili, enobukhulu obuphelele obungu-≥600μm, obungakwazi ukuhlangabezana nezidingo ezingenhla.
