Ulwazi mayelana nokuthenga okukhiyiwe emnyango

Kunezinhlobo eziningi zabakhona isikhathi sokubona iminwe. Ngenxa yokusetshenziswa okuhlukile kanye nezindawo zokusebenzisa, ukugxila lapho ukuthenga kuzokwehluka, kepha abanye ulwazi lokuthenga oluyisisekelo oluyisisekelo lusendaweni yonke. Manje ake sikhulume ngolwazi lokukhethwa kokhiye ngokuningiliziwe.

1. Amaphaneli nezibambiso: izinto eziphambili zamaphaneli wokukhiya umnyango nezibambo kufaka phakathi i-zinc alloy, i-aluminium alloy, ithusi, insimbi engagqwali, i-carbon yensimbi, njll.
① Izinto ezibonakalayo ze-Zinc Alloy: kungenye yezinto ezisetshenziswa kakhulu zokukhiya. Inamandla amahle nokumelana nokugqwala, futhi kulula ukwenza izingxenye ngamaphethini ayinkimbinkimbi, ikakhulukazi ukucindezela kwengcindezi. Izikhiye ze-Zinc Alloy zingumkhiqizo ojwayelekile emakethe yamanje.
I-②Aluminum Alloy: I-Aluminium Alloy futhi isetshenziswa kalula esetshenziswayo yokukhiya ngoba ishibhile futhi kulula ukuyicubungula. Phakathi kwazo, i- "Space Aluminium" Lock iyathandwa yiqembu lemfashini ngenxa yomqondo wayo oqinile wobuchwepheshe nobuchwepheshe.
③Brass: Inezakhiwo ezinhle zemishini, ukumelana kahle nokugqwayiza nokusebenza, nombala okhanyayo, izibambo ezakhiwe ngokukhethekile, nezinye izingxenye zokuhlobisa, ezinobunzima bokuhlobisa, nobunzima obuhle, kanye nama-pores noma ama-blisters. Intengo iphakeme.
Insimbi engapheli: ihlala isikhathi eside, igqame ngokusetshenziswa. Inamandla amahle, ukumelana okuqinile kokugqwala nombala ongashintshiwe.
I-⑤Carbon Steel: Inamandla angcono nezindleko eziphansi. Imvamisa ihlanganiswa, kepha kulula ukugqwala.
2. IZINTO ZOKUQAPHELA Lapho uthenga izingidi
① Bheka ukuthi izimpawu zokufaka zomkhiqizo othengiwe ziphelele, ngabe ukupakishwa kuqinile, nokuthi okuqukethwe kwencwadi yokufundisa ehambelana nomkhiqizo. Qikelela ukugwema ukweqisa okungahambelani namaqiniso.
Bheka ukubukeka nekhwalithi yomkhiqizo, kufaka phakathi ikhanda lokukhiya, umzimba wokukhiya, izingxenye zokukhiya, izingxenye ezihlobene nezingxenye ezihlobene nezinto ezihlobene nezingxenye ezihlobene nezithonjana ezinemidwebo yokufafaza zigqamile futhi zigqoke umfaniswano, futhi Noma ngabe kunezimpawu zokugqwala, i-oxidation noma ukulimala.
③ Bheka ukuthi umsebenzi womkhiqizo uthembekile futhi uvumelana nezimo. Kufanele ukhethe imikhiqizo emibili noma eminingi yokuqhathanisa nokuhlola. Ikakhulu lapho uthenga imikhiqizo yokukhiya yendlela emibili, kufanele usebenzise zonke izinkinobho zokuhlola ukuvulwa nokuvalwa kwezikhiye zangaphakathi nangaphandle ngokulandelana. Kufanele futhi uhlole indlela yokuphepha yomkhiqizo. Kunconywa ukuzama ukukhiya ngakunye okungenani amahlandla amathathu.
Ifenisha ④choose ngokuya ngemvelo yokusebenzisa, njengesakhiwo somnyango, ubukhulu, ukusekwa kwesokunxele noma kwesokudla, ukuvula kwangaphandle, njll.
Inani lokuvula elihlanganayo liyisilinganiso sokuvula esivumelana sokhiye kanye nokhiye. Izikhiye ezimbalwa ezivulwa ukhiye owodwa, ziqine ukuphepha nokwethenjwa kokhiye.
