Amapayipi ensimbi engagqwali, ngakolunye uhlangothi, enziwe ngensimbi ye-alloy futhi ngokwemvelo anokumelana nokugqwala, asusa i-ne...Funda kabanzi -
Ingabe insimbi engaphekiwe iyagqwala? Kungavinjelwa kanjani?
Lapho izinto zensimbi ezithathiwe zidinga ukugcinwa futhi zithuthwe eduze, izinyathelo ezanele zokuvimbela kufanele zithathwe ukuvimbela ukugqwala. Izinyathelo eziqondile zokuvimbela zimi kanje: 1. Izindlela zokwelapha ezingaphezulu zingasetshenziswa ukunciphisa ukufo...Funda kabanzi -
Indlela yokusika insimbi?
Isinyathelo sokuqala sokucutshungulwa kwensimbi ukusika, okubandakanya ukumane uhlukanise izinto ezingavuthiwe noma ukuzihlukanisa zibe izimo ukuze uthole izikhala ezingenalutho. Izindlela ezijwayelekile zokusika insimbi zihlanganisa: ukusika isondo lokugaya, ukusika amasaha, ukusika amalangabi, ukusika i-plasma, ukusika i-laser,...Funda kabanzi -
Izinyathelo zokuqapha ukwakhiwa kwekholvethi kathayela esimweni sezulu esihlukile nezimo zezulu
Esimweni sezulu esihlukile sensimbi yokwakhiwa kwekholvert kathayela izinyathelo zokuphepha azifani, ubusika nehlobo, izinga lokushisa eliphezulu kanye nezinga lokushisa eliphansi, imvelo ihlukile izinyathelo zokwakha nazo zihlukile. 1.Isimo sezulu esishisayo esinothayela...Funda kabanzi -
Ukuqhathaniswa kwezinzuzo kanye nokubi kokusetshenziswa kwe-tube yesikwele, insimbi yesiteshi, insimbi ye-angle
Izinzuzo zeshubhu yesikwele Amandla aphezulu acindezelayo, amandla amahle okugoba, amandla aphezulu okugoqa, ukuzinza okuhle kosayizi wesigaba. Ukushisela, ukuxhumeka, ukucutshungulwa kalula, ipulasitiki enhle, ukugoba okubandayo, ukusebenza kokugoqa okubandayo. Indawo enkulu, insimbi encane ngeyunithi ngayinye...Funda kabanzi -
Uyini umehluko phakathi kwe-carbon steel ne-stainless steel?
I-Carbon steel, eyaziwa nangokuthi i-carbon steel, ibhekisela ku-iron ne-carbon alloys equkethe ngaphansi kuka-2% we-carbon, i-carbon steel ngaphezu kwe-carbon ngokuvamile iqukethe inani elincane le-silicon, i-manganese, isulfure ne-phosphorus.
