◉Kwintlalo yanamhlanje, intsimbi engagqwaliyo iye yaba yinto eqhelekileyo nebalulekileyo esetyenziswa kakhulu ekwakheni, ekuveliseni nasekuphileni kwemihla ngemihla. Kukho iintlobo ezininzi ezahlukeneyo zentsimbi engagqwaliyo, kuquka iimodeli eziqhelekileyo ezifana ne-201, 304 kunye ne-316.
Nangona kunjalo, kwabo bangaziqondiyo iimpawu zezinto ezisetyenzisiweyo, kulula ukudideka ngumahluko phakathi kwezi modeli. Eli nqaku liza kuchaza umahluko phakathi kwentsimbi engagqwaliyo engu-201, 304 kunye no-316 ukunceda abafundi baqonde ngcono iimodeli ezahlukeneyo zezinto zentsimbi engagqwaliyo kwaye banike iingcebiso zokuthenga intsimbi engagqwaliyo.
◉Okokuqala, umahluko kwimilo yeekhemikhali
Ukwakheka kweekhemikhali zentsimbi engagqwaliyo yinto ebalulekileyo ekumiseleni ukusebenza kwayo kunye neempawu zayo.Intsimbi engenasici 201, 304 kunye no-316 kukho umahluko ocacileyo kwimilo yeekhemikhali. Intsimbi engatyiwayo 201 iqulethe i-17.5% -19.5% ye-chromium, 3.5% -5.5% ye-nickel, i-nitrogen kunye ne-0.1%-0.5%, kodwa akukho molybdenum.
Kwelinye icala, intsimbi engagqwaliyo 304 ine-18%-20% ye-chromium, 8%-10.5% ye-nickel, kwaye ayinayo i-nitrogen okanye i-molybdenum. Ngokwahlukileyo koko, intsimbi engagqwaliyo 316 ine-16%-18% ye-chromium, 10%-14% ye-nickel, kunye ne-2%-3% ye-molybdenum. Ukusuka kwimilo yeekhemikhali, intsimbi engagqwaliyo 316 inokumelana nokugqwala okuphezulu kunye nokumelana ne-asidi, ifaneleke ngakumbi ukusetyenziswa kwiindawo ezithile ezikhethekileyo kunentsimbi engagqwaliyo 201 kunye ne-304.
◉Okwesibini, umahluko ekuchaseni ukugqwala
Ukumelana nokugqwala luphawu olubalulekileyo lokusebenza kwentsimbi engagqwali. Intsimbi engagqwali 201 inokumelana nokugqwala okuhle kwii-asidi ezininzi ze-organic, ii-asidi ezingaphiliyo kunye nezisombululo zetyuwa kubushushu begumbi, kodwa iya kugqwala kwindawo enamandla ye-alkaline. Intsimbi engagqwali 304 inokumelana nokugqwala okuhle kwaye ifanelekile kwiindawo ezininzi ezigqwaliyo ngokubanzi.
Intsimbi engagqwaliyo 316, kwelinye icala, igqwesile ekumelaneni nokugqwala, ingakumbi kwiindawo ezine-asidi kunye neemeko zobushushu obuphezulu kunye nokumelana nokugqwala okugqwesileyo, okusetyenziswa rhoqo kwiikhemikhali, zaselwandle nakwezinye izinto. Ke ngoko, xa uthenga izinto zentsimbi engagqwaliyo, kubalulekile ukukhetha imodeli efanelekileyo ngokwendlela ethile yokusetyenziswa kweendawo ezahlukeneyo.
◉Okwesithathu, umahluko kwiipropati zoomatshini
Iimpawu zoomatshini zentsimbi engagqwali ziquka izalathisi ezinje ngamandla, ukuguquguquka kunye nobunzima. Ngokubanzi, amandla entsimbi engagqwali 201 aphezulu kancinci kunentsimbi engagqwali 304, kodwa aphantsi kakhulu kunentsimbi engagqwali 316. Intsimbi engagqwali 201 kunye ne-304 ziguquguquka kakuhle, kulula ukuzicubungula nokuzibumba, zifanelekile kwezinye zeemfuno zokusebenza kokucubungula izinto kwiimeko eziphezulu.
Amandla aphezulu entsimbi engagqwaliyo angama-316, kodwa ikwanokumelana nokuguguleka okuhle kunye nokumelana nokutsalwa, ifanelekile ukumelana namandla aphezulu kunye nobushushu obuphezulu. Ke ngoko, xa ukhetha izinto zentsimbi engagqwaliyo, kufuneka wenze ukhetho olufanelekileyo ngokweemfuno ezithile zoomatshini kunye nokusetyenziswa kwendalo.
◉Okwesine, umahluko wamaxabiso
Kukwakho umahluko othile kwixabiso lentsimbi engagqwaliyo engu-201, 304 kunye ne-316. Ngokubanzi, ixabiso lentsimbi engagqwaliyo engu-201 liphantsi kakhulu, lifikeleleka lula. Ixabiso lentsimbi engagqwaliyo engu-304 liphezulu kakhulu, kodwa ngenxa yoluhlu olubanzi lwezicelo kunye nokusebenza okungcono ngokubanzi, iseyenye yeemodeli zentsimbi engagqwaliyo ezixhaphakileyo kwimarike.
◉ Intsimbi engagqwaliyo 316 ibiza kakhulu ngenxa yokumelana kwayo nokugqwala kunye neempawu zayo zoomatshini, kwaye ifanelekile kwiindawo ezithile ezikhethekileyo ezifuna iimpawu eziphezulu zezinto. Ke ngoko, xa uthenga izinto zentsimbi engagqwaliyo, kufuneka uqwalasele izinto ezifana nokusebenza kwezinto kunye nohlahlo lwabiwo-mali.
