Self drilling screw is mechanical base part, iri kudiwa zvikuru. Kazhinji, mabhaudhi, screws, rivets, nezvimwewo, kuitira kuve nechokwadi chekuchengetedza kana kazhinji hazvidi kufunga nezve pesvedzero yekushisa, nharaunda yakaipa kana mamwe mamiriro ekushanda ane ngozi. Zvishandiso zvakajairika isimbi kabhoni, yakaderera alloy simbi uye isiri-ferrous simbi. Asi kunyanya zviitiko, zvekusimbisa zvinhu zvinoda kusangana nemamiriro ekuora kwakanyanya kana simba rakawanda, kune akawanda simbi isina tsvina uye ekupedzisira simba resimbi isina tsvina akabuda. Matambudziko matanhatu anotevera anofanirwa kutariswa kana uchishandisa nekuchengetedza iyo yekuchera muswe waya:
1. Nzira yekusuka waya yekuchera muswe inokurumidza uye inoda kuchenjerera. Munguva yekugadzira, pachava nemasara pamusoro peiyo yekuchera muswe waya. Iyi nhanho ndeyekusuka mushure mekunge silicate cleaner yagezwa.
2. Munguva yekupisa, iyo stack inofanira kusanganiswa, zvikasadaro zvishoma oxidation ichaitika mumafuta anodzima.
3. White phosphide residues ichaonekwa pamusoro pepamusoro-simba screws, zvichiratidza (pfungwa 1) kuti kuongorora hakusi kungwarira zvakakwana panguva yekushanda. 4. Chiitiko chekusviba pamusoro pezvikamu zvinogadzira kemikari reverse application, zvichiratidza kuti kupisa kwekupisa hakuna kuitwa zvakakwana uye zvakasara zve alkaline pamusoro pepamusoro hazvina kubviswa zvachose.
5. Zvikamu zvakajairika zvichaita ngura mukusuka, uye mvura inoshandiswa pakusuka inofanira kuchinjwa kazhinji.
6. Kuora kwakanyanyisa kunoratidza kuti mafuta ekudzima akashandiswa kwenguva yakareba, uye inoda kuwedzerwa kana kuchinjwa.
