Imilinganiselo yoLawulo loMgangatho
Phantse zonke isinyithi zidleka phantsi kweemeko ezithile. Xa ii-athomu zetsimbi zixutywe ngulwelo, i-corrosion iya kwenzeka, kubangele ukulahlekelwa kwezinto ezibonakalayo kwi-metal surface. Oku kunciphisa ubukhulu bamacandelo afanaiiferruleskwaye ibenza bathande ukusilela koomatshini. Iindidi ezininzi zomhlwa zinokwenzeka, kwaye uhlobo ngalunye lokutya lubeka isoyikiso, ngoko ke kubalulekile ukuvavanya eyona mathiriyeli yesicelo sakho.
Nangona ukubunjwa kweekhemikhali zezinto eziphathekayo kunokuchaphazela ukuxhathisa ukubola, enye yezona zinto zibalulekileyo zokunciphisa ukungaphumeleli okubangelwa yiziphene eziphathekayo ngumgangatho opheleleyo wezinto ezisetyenzisiweyo. Ukususela kwi-bar qualification ukuya ekuhlolweni kokugqibela kwamacandelo, umgangatho kufuneka ube yinxalenye ebalulekileyo yekhonkco ngalinye.
Ulawulo lweNkqubo yeMathiriyeli kunye noHlolo
Eyona ndlela yokuthintela iingxaki kukuzifumana ngaphambi kokuba zenzeke. Enye indlela kukuqinisekisa ukuba umthengisi uthatha amanyathelo angqongqo olawulo lomgangatho ukuthintela umhlwa. Oko kuqalwa kulawulo lwenkqubo kunye nokuhlolwa kwesitokhwe sebha. Inokuthi ihlolwe ngeendlela ezininzi, ukusuka ekuqinisekiseni ngokubonakalayo ukuba izinto eziphathekayo zikhululekile kuzo naziphi na iziphene ezingaphezulu ukuya ekuqhubeni iimvavanyo ezikhethekileyo zokubona uvakalelo lwento kwi-corrosion.
Enye indlela ababoneleli abanokukunceda ngayo uqinisekise ukufaneleka kwemathiriyeli kukukhangela umxholo wezinto ezithile ekubunjweni kwemathiriyeli. Ukumelana nokugqwala, amandla, i-weldability kunye ne-ductility, indawo yokuqala kukuphucula ukubunjwa kweekhemikhali ze-alloy. Ngokomzekelo, umxholo we-nickel (Ni) kunye ne-chromium (CR) kwi-316 yensimbi engenasici iphezulu kuneemfuno ezincinci ezichazwe kwi-ASTM International (ASTM) yomgangatho womgangatho, okwenza izinto zibe nokumelana nokugqwala okungcono.
KwiNkqubo yeMveliso
Ngokufanelekileyo, umthengisi kufuneka ahlole amacandelo kuwo onke amanyathelo enkqubo yokuvelisa. Inyathelo lokuqala kukuqinisekisa ukuba imiyalelo yemveliso echanekileyo iyalandelwa. Emva kwamacandelo okuvelisa, ezinye iimvavanyo kufuneka ziqinisekise ukuba iinxalenye zenziwe ngokuchanekileyo kwaye akukho ziphene ezibonakalayo okanye ezinye iziphene ezinokuthintela ukusebenza. Iimvavanyo ezongezelelweyo kufuneka ziqinisekise ukuba amacandelo asebenza njengoko kulindelekile kwaye atywinwe kakuhle.
