Amanyathelo olawulo lomgangatho
Phantse zonke ii-corrode zensimbi phantsi kweemeko ezithile. Xa ii-atom zentsimbi zixinezelwe ngulwelo, i-corrosion ziya kwenzeka, zikhokelela ekulahlekelweni ngezinto ezibonakalayo kumphezulu wensimbi. Oku kunciphisa ubukhulu bezinto ezinjeferruleskwaye ibenze thandeke ngakumbi ukusilela koomatshini. Iindidi ezininzi ze-corosion zinokwenzeka, kwaye uhlobo ngalunye lwe-corosion lubeka isoyikiso, ke kubalulekile ukuvavanya ezona zixhobo zibalaseleyo kwisicelo sakho
Nangona ubume bemichiza yezinto zekhemikhali kunokuchaphazela ukumelana nokunganyangeki, yenye yezona zinto zibalulekileyo ukunciphisa ukungabikho kwesiphene sezinto ezisetyenzisiweyo. Ukusuka kwisiqinisekiso se-BAR ukuya kuhlolo lokugqibela lwamacandelo, umgangatho kufuneka ube yinxalenye yekhonkco ngalinye.
Inkqubo yenkqubo yezinto ezibonakalayo kunye nokuhlolwa
Eyona ndlela ilungileyo yokuthintela iingxaki kukufumana ngaphambi kokuba zenzeke. Enye indlela kukuqinisekisa ukuba umthengi uthatha amanyathelo alawula umgangatho ophantsi ukukhusela ukususwa. Oko kuqala kulawulo lwenkqubo kunye nokuhlolwa kwe-bar stock. Inokuhlolwa ngeendlela ezininzi, ukusuka kwi-proous ebonakalayo iqinisekisa ukuba izinto ezibonakalayo zikhululekile kuzo nakwezinye iziphene zokuqhuba uvavanyo olukhethekileyo lokufumana ubuntununtunu bomxholo wokungazithembi.
Enye indlela abathengisi banokukunceda uqinisekise ukufaneleka kwesixhobo kukujonga umxholo wezinto ezithile ekufumaneni umxholo. Ukuxhathisa ukuxhaphaza, amandla, ububi kunye nolangazeli, indawo yokuqala kukwandisa ukwakhiwa kweekhemikhali kwe-alloy. Umzekelo, umxholo weNickel (NI) kunye neChromium (CR) kwi-316 intsimbi engaphezulu kweyona mifuziselo ichazwe kwi-ASTM yeLizwe (i-ASTM), eyenza ukuba izinto zibe nokunganyangeki kakuhle.
Kwinkqubo yemveliso
Ngokufanelekileyo, umthengisi kufuneka ahlole izinto kuwo onke amanyathelo kwinkqubo yemveliso. Inyathelo lokuqala kukuqinisekisa ukuba kulandelwa imiyalelo yemveliso efanelekileyo. Emva kokwenza izinto zokwenza, ezinye iimvavanyo kufuneka ziqinisekise ukuba iinxalenye zenziwe ngokuchanekileyo kwaye akukho ziphene zibonakalayo okanye ezinye iziphene ezinokuthi zithintele ukusebenza. Uvavanyo olongezelelekileyo kufuneka luqinisekise ukuba amacandelo asebenza njengoko kulindelwe kwaye atywinwe kakuhle.
