    Iinkcukacha zeMveliso

    Iithegi zeMveliso

    Kwihlabathi loyilo nolwakhiwo lobunjineli, ukuba nemibhobho yentsimbi ethembekileyo neguquguqukayo kubalulekile. Umbhobho wentsimbi we-A252 GRADE 3 uhambelana kakuhle nale nkcazo, nto leyo eyenza ukuba ube yenye yeentlobo zemibhobho yentsimbi esetyenziswa kakhulu kumashishini. Ngenxa yamandla ayo aphezulu kunye nokumelana nokugqwala, lo mbhobho wentsimbi uzisa utshintsho olungazange lubonwe ngaphambili ekwakhiweni kwemibhobho yendle.

    Umbhobho wentsimbi we-A252 GRADE 3yaziwa ngamandla ayo okutyhala aphezulu, idlula ezinye iintlobo zemibhobho yentsimbi. Inokumelana okukhulu kokutyhala nokucinezela, okuqinisekisa uzinzo oluhle kakhulu kwisakhiwo. Olu phawu luba lubaluleke kakhulu apho imibhobho yendle ithwaxwa yimithwalo emikhulu ukuqinisekisa ukusebenza okuthembekileyo nokuhlala ixesha elide. Iingcali kwicandelo lobunjineli zinokuthemba le mbhobho yentsimbi ukuba ikwazi ukumelana neemeko ezinzima.

    Olunye uphawu oluphawulekayo lombhobho wentsimbi we-A252 Grade 3 kukulungiswa komphezulu wawo. Ukuqinisekisa umgangatho ophezulu, imibhobho iphathwa ngononophelo ukuthintela i-oxidation kunye nokugqwala. Oku kuthetha ukuba umbhobho unokusebenza kwiindawo ezinokonakalisa kakhulu ezifana neelwandle, iingxangxasi kunye nezityalo zeekhemikhali ngaphandle kokuphazamisa ukusebenza kwawo. Ukuqina komphezulu wombhobho kwenza ukuba ube lukhetho oluhle kakhulu kwiiprojekthi ezifuna ukumelana nokugqwala okuphezulu.

    Ukuguquguquka kombhobho wentsimbi we-A252 Grade 3 kungqinwe luluhlu olubanzi lwezicelo zawo. Ukongeza kwimpembelelo yawo kulwakhiwo lwemijelo yamanzi amdaka, ingasetyenziswa kumashishini ahlukeneyo kuquka ioyile negesi, unyango lwamanzi kunye neeprojekthi zeziseko zophuhliso. Olu kuguquguquka lwenza kube lukhetho lokuqala kwiinjineli kunye nabakhi abafuna izisombululo zemibhobho yentsimbi ezithembekileyo nezisebenzayo kwiiprojekthi zabo.

    Umbhobho we-X42 SSAW

    Xa kufikwa kuumjelo wokuhambisa amanzi amdakaumgcaulwakhiwo, imibhobho yentsimbi ye-A252 Grade 3 iyabonakala. Amandla ayo agqwesileyo kunye nokumelana nokugqwala kuyayihlukanisa neminye imibhobho yentsimbi ethengiswayo. Ngokukhetha olu hlobo lombhobho, iinjineli zinokuqiniseka ukuba iprojekthi yazo iya kuhlala ixesha elide, iqinisekisa ukuqina kunye nokuzinza koyilo lwayo.

    Ngamafutshane, umbhobho wentsimbi we-A252 GRADE 3 utshintsha umdlalo kulwakhiwo lombhobho wendle kunye nolwakhiwo lwawo oludibeneyo olune-arc engaphantsi komhlaba. Amandla ayo angaqhelekanga okutsalwa kunye nokumelana nokugqwala kwenza ukuba ibe lukhetho olufanelekileyo kwiinjineli ezifuna izisombululo zemibhobho yentsimbi ezinokuthenjwa neziguquguqukayo. Nokuba kukuzinza kwesakhiwo okanye isidingo sokumelana neendawo ezinomhlwa kakhulu, lo mbhobho wentsimbi udlula ulindelo. Yamkela umbhobho wentsimbi we-A252 GRADE 3 kwaye ufumane umgangatho ongenakuthelekiswa nanto owuzisayo kumsebenzi wakho wobunjineli.
