Iziteshi ze-C zensimbi engagqwali
Incazelo emfushane:
Iziteshi zensimbi engagqwali ziyizingxenye zesakhiwo ezenziwe ngensimbi engagqwali, i-alloy engagqwali eyakhiwe ngokuyinhloko ngensimbi, i-chromium, i-nickel, nezinye izakhi.
Iziteshi Zensimbi Engagqwali:
Iziteshi zensimbi engagqwali ziyiphrofayili yesakhiwo eyenziwe ngama-alloy ensimbi engagqwali angagqwali, anesigaba esifana no-C noma u-U, esifanele ukusetshenziswa ekwakheni, embonini, nasezindaweni zasolwandle. Ngokuvamile zikhiqizwa ngezinqubo zokugoba ezishisayo noma ezibandayo, zinikeza ukumelana nokugqwala okuhle kakhulu kanye nokusekelwa kwesakhiwo, okusetshenziswa kabanzi ekwakheni ozimele, imishini yokukhiqiza, ubunjiniyela basolwandle, kanye nezinye izinhlelo zokusebenza ezahlukahlukene. Kuye ngezincazelo ezisungulwe yizindinganiso ezifana ne-ASTM, EN, njll., amazinga ahlukene ensimbi engagqwali afana no-304 noma u-316 angakhethwa ukuze kuhlangatshezwane nezidingo ezithile zephrojekthi ethile. Iziteshi zensimbi engagqwali zingaba nokuqedwa okuhlukile kobuso, njengokuqeda okupholishiwe, okubhulashiwe, noma okugaya, kuye ngokusetshenziswa okuhlosiwe kanye nezidingo zobuhle.

Ungawugoba kanjani isiteshi sensimbi engagqwali?
Ukugoba iziteshi zensimbi engagqwali kudinga ukusetshenziswa kwamathuluzi nezindlela ezifanele. Qala ngokumaka izindawo zokugoba esiteshini bese usiqinisa emshinini wokugoba noma ebhuleki lokucindezelwa. Lungisa izilungiselelo zomshini, yenza ukugoba kokuhlola ukuqinisekisa ukunemba, bese uqhubeka nokugoba kwangempela, uqaphe ngokucophelela inqubo bese uhlola i-engeli yokugoba. Phinda inqubo yezindawo eziningi zokugoba, yenza noma yikuphi ukuthinta kokuqeda okudingekayo njengokususa i-bursting, bese unamathela eziqondisweni zokuphepha ngokugqoka imishini yokuzivikela efanele kuyo yonke inqubo.
Yiziphi izinhlelo zokusebenza zesiteshi sensimbi engagqwali?
Insimbi yesiteshi iyinto yokwakha eguquguqukayo esetshenziswa kabanzi ekwakheni, ekukhiqizeni, ezimotweni, olwandle, emandleni, ekudluliseni amandla, ubunjiniyela bezokuthutha, kanye nasekukhiqizweni kwefenisha. Ukuma kwayo okuhlukile, kuhlanganiswe namandla aphezulu kanye nokumelana nokugqwala, kuyenza ibe yisinqumo esihle kakhulu sokwakha izinhlaka, izakhiwo zokusekela, imishini, ishasi yezimoto, ingqalasizinda yamandla, kanye nefenisha. Insimbi yesiteshi yensimbi engagqwali ivame ukusetshenziswa emikhakheni yamakhemikhali neyezimboni ukuze kukhiqizwe izisekelo zemishini kanye namabhuleki epayipi, okugqamisa ukubaluleka kwayo kuzo zonke izimboni.
Yiziphi izinkinga ngokugoba kwe-engeli yesiteshi?
Izinkinga nge-engeli yokugoba yeziteshi zensimbi engagqwali zingase zihlanganise ukungalungi, ukugoba okungalingani, ukuphambuka kwezinto, ukuqhekeka noma ukuqhekeka, ukubuyela emuva kwentwasahlobo, ukuguguleka kwamathuluzi, ukungapheleli kwendawo, ukuqina komsebenzi, kanye nokungcola kwamathuluzi. Lezi zinkinga zingavela ezintweni ezifana nezilungiselelo zomshini ezingalungile, ukushintshashintsha kwezinto, amandla amaningi, noma ukunganakekelwa kahle kwamathuluzi. Ukuze kuxazululwe lezi zinkinga, kubalulekile ukunamathela ezinqubweni ezifanele zokugoba, ukusebenzisa amathuluzi afanele, ukugcina imishini njalo, nokuqinisekisa ukuthi inqubo yokugoba ihambisana namazinga embonini, ukunciphisa ingozi yokubeka engcupheni ikhwalithi, ukunemba, kanye nobuqotho besakhiwo seziteshi zensimbi engagqwali.
