Argon welding
I-Argon welding isebenzisa i-argon njengendlela yokukhusela igesi yokuwelda, ebizwa ngokuba yi-argon gas welding.Oko kukuthi, ujikeleze i-arc yegesi ye-argon emoyeni ekwanti ukusuka kwindawo ye-welding, ukuthintela i-oxidation ye-weld zone.Ubuchwephesha bokuwelda beArgon busekwe kumgaqo jikelele wearc weldi...Funda ngokugqithisileyo -
Ukwakhiwa kombhobho wentsimbi yesamente yodaka
Ukwakhiwa kodaka lwesamente ngeendlela ezimbini.I-centrifugation yomgangatho wokuqala.Ikakhulu ifanelekile kwimibhobho ehlanganiswe nokwakhiwa kwe-DN400 caliber okanye ngaphantsi.Kodwa ukutshiza phantsi komhlaba, ikakhulu kusetyenziswa kwi-DN700 yokwakhiwa kombhobho wedayamitha ngaphezulu komhlaba.Umbhobho wesamente wodaka: umxube wec...Funda ngokugqithisileyo -
Iyunithi yombhobho obandayo
I-cold-rolled, i-cold-drawn okanye i-cold-rolled and cold draw indibaniselwano yenkqubo yokusebenza ebandayo yokuvelisa iphakheji yombhobho yokudibanisa izixhobo.Ngumbhobho odityanisiweyo oshushu-oshushu okanye iiyunithi zokulungisa ubunzulu betyhubhu.Ngokusekelwe kwiipropati zokucubungula isinyithi, ubungakanani bombhobho, iimfuno zomgangatho ...Funda ngokugqithisileyo -
Inkqubo yokuchola umbhobho wentsimbi
Oku kubizwa ngokuba kukuchola kusetyenziswa i-hydrofluoric acid kunye nesisombululo se-nitric acid ukuhlamba umphezulu wentsimbi oksayidi oveliswe emva kokunyangwa ngobushushu.Isetyenziswe ekubunjweni kwesisombululo kunye nemilinganiselo yokulinganisa: i-HF (3-8%), i-HNO3 (10-15%), i-H2O (imali eseleyo) xa kusetyenzwa ubushushu besisombululo kwi-40-60 °C.Umfanekiso wombhobho wentsimbi...Funda ngokugqithisileyo -
Umbhobho wokuhambisa amanzi
Umbhobho wokuhambisa amanzi amdaka ubhekiselele ekuqokeleleni nasekukhutshelweni kogutyulo, amanzi amdaka kunye nenkqubo yokuhanjiswa kwemibhobho yamanzi emvula kunye nezibonelelo ezinxulumeneyo.Kubandakanya umbhobho owomileyo, umbhobho wesebe kunye nombhobho okhokelela kwizityalo zonyango, Kungakhathaliseki ukuba umbhobho okwisitalato okanye kuyo nayiphi na enye indawo, nje ukuba badlala ...Funda ngokugqithisileyo -
Uhlobo loMbhobho weSsimbi osetyenziselwa ukuThuthwa kweOli
Ukusetyenzwa, ukuthuthwa kunye nokugcinwa kwe-oyile kuyinkimbinkimbi kakhulu kunye noxinzelelo oluphezulu kunye nokuhlwa.I-oyile ekrwada esuka ngaphantsi komhlaba iqulethe izinto ezifana nesulfure kunye nehydrogen sulfide enokuthi ifake ioksidi kumbhobho.Le yingxaki ephambili ngexesha lokuthuthwa kweoli.Ke ngoko, izinto ...Funda ngokugqithisileyo
