Kodi chitsulo chaulere ndi chiani?
Chitsulo chaulere ndi dzina la mpweya wabwino ndi zinthu zina zowonjezera pazinthu zokhazokha zowongolera makina awo ndi chip. Amadziwikanso kuti amadula kapena odula.
Zitsulo zaulere zimagawidwa m'magulu atatu
l11xx: Kuchuluka kwa sulfure (s) kumachulukitsidwa kuchokera ku 0,05% mu ma carbon ma carbon to 0.1%. Imawonjezera pafupifupi 20% ku Makina ophatikizidwa ndi zinthu zofanana mu 10xx mndandanda. Kumbali inayi, mphamvu ya anthu imachepa ndi pafupifupi 10%, ndipo zinthuzo zimakhala zopanda pake.
l12xx mndandanda: Sulfur (s) zomwe zimachulukitsidwa mpaka 0,25%, ndi phosphorous (p) zochulukitsidwa kuchokera ku 0.04% mu 10xx mndandanda wa 10,5%. Zotsatira zake, makinawo amakula ndi 40% pamtengo wotsika kwambiri pamakina.
lSae 12l14 ndi mfulu Kudula zitsulo komwe phosphorous yasinthidwa ndi 0,25% ya lead (PB), yomwe imakulitsa makina ena 35%. Kusintha kumeneku kumachitika chifukwa kutsogolera kumasungunuka komwe kuli komwe kumaduka, motero kuchepetsa mikangano ndikupereka mafuta achilengedwe. Komabe, opanga zinthu zambiri ndi zogulitsa zamakina amayesa kupewa kutsogolera chifukwa cha kuwonongeka kwa chilengedwe ndi zoopsa zaumoyo.
Momwe mungasankhire zosewerera zaulere
Jindwai chitsulo ndi wokhazikika komanso wotsogolera wachitsulo, wotsatsa, otumiza kunja, ogawana mitundu ya mitundu yopanga chitsulo monga chitoliro, mabisi, bar ndi ndodo. Zogulitsa zachitsulo zimapereka kwa ife kupangidwa kuchokera ku zida zapamwamba kwambiri ndipo ndizogwirizana kwambiri ndi mafakitale monga anyezi ndi asme kapena asme kapena miyezo ina yabwino.Jindwai chitsulo pezani ndi kusunga mndandanda waukulu wa Astm 12l14, Aisi 12L14 (Chida, Chida Cha Makina, Zojambula Zapamwamba, Zojambula Zida, etc. Zambiri, chonde lemberani.
