Yintoni umahluko kwi-coefficient yokwanda kwe-thermal phakathi kwebhedi yentsimbi kunye nebhedi ye-mineral cast? Lo mahluko ukuchaphazela njani ukuchaneka komatshini kwiindawo ezahlukeneyo zobushushu?

 

IGranite vs. I-Cast Iron kunye neMineral Casting Bed: Ukuqonda i-Thermal Expansion Coefficients kunye nempembelelo yazo ekuChanekeni kwesixhobo soMatshini

Xa kuziwa ekwakhiweni kweebhedi zesixhobo somatshini, izinto ezifana negranite, isinyithi esityhidiweyo, kunye ne-mineral casting zisetyenziswa ngokuqhelekileyo ngenxa yeempawu zabo ezizodwa. Enye into ebalulekileyo ekufuneka iqwalaselwe ekukhetheni ezi mathiriyeli kukwandiswa kwe-thermal coefficient, ngakumbi kwiindawo ezinobushushu obahlukeneyo. Umahluko kwi-coefficients yokwandiswa kwe-thermal phakathi kwentsimbi yentsimbi kunye neebhedi zokulahla izimbiwa zinokuchaphazela kakhulu ukugcinwa ngokuchanekileyo kwezixhobo zoomatshini kwiindawo ezahlukeneyo zokushisa.

Intsimbi yokuphosa, imathiriyeli yemveli esetyenziswa ekwakhiweni kwesixhobo soomatshini, inomlinganiselo wokwandiswa kwe-thermal ephezulu. Oku kuthetha ukuba njengoko amaqondo obushushu eguquguquka, iibhedi zentsimbi zithande ukwanda kunye nokucutheka, okunokukhokelela kutshintsho olunobungakanani kwisixhobo somatshini. Kwelinye icala, ukuphoswa kweeminerali, okuhlala kusenziwa ngezinto ezifana ne-epoxy resin kunye ne-granite aggregates, kunomlinganiselo ophantsi wokwandisa i-thermal xa kuthelekiswa nentsimbi. Olu phawu luvumela iibhedi zokugalela izimbiwa ukuba zibonise utshintsho oluncinci lwe-dimensional ekuphenduleni ukuguquguquka kobushushu.

Impembelelo yalo mahluko ibaluleke kakhulu kwiindawo apho ulawulo lobushushu lucela umngeni. Kwiindawo ezinobushushu obuphezulu, i-coefficient ephezulu yokwandisa i-thermal yentsimbi etyhidiweyo inokukhokelela ekungalungi kwe-dimensional kwisixhobo somatshini, okuchaphazela ukuchaneka kwayo kunye nokusebenza kwayo. Ngokuchasene noko, iibhedi zokuphosa iiminerali, kunye ne-coefficient yazo yokwandisa i-thermal ephantsi, zixhotyiswe ngcono ukugcina ukuchaneka kwiimeko ezinjalo.

Ngokwahlukileyo koko, kwiindawo ezinobushushu obuphantsi, i-coefficient esezantsi yokwandiswa kwe-thermal ye-mineral casting ingabangela isakhiwo esiqinileyo xa kuthelekiswa nentsimbi etyhidiweyo, enokuthi ichaphazele impendulo eguqukayo yesixhobo somatshini kunye neempawu zokudambisa ukungcangcazela. Ukuqonda lo mahluko kubalulekile ukuba abavelisi kunye nabasebenzisi benze izigqibo ezinolwazi ngokusekelwe kwiimeko ezithile zokushisa apho isixhobo somatshini siya kusebenza.

Ukuqukumbela, i-coefficient yokwandisa i-thermal idlala indima ebalulekileyo ekukhethweni kwezinto eziphathekayo kwiibhedi zesixhobo somatshini. Ngelixa i-iron cast ibe yinto ekhethiweyo yendabuko, i-coefficient ephantsi yokwandisa i-thermal ye-mineral casting, ehlala ibandakanya i-granite, inikezela ngeenzuzo ekugcineni ukuchaneka kwiindawo ezahlukeneyo zokushisa. Ngokuqwalasela ezi zinto, abavelisi kunye nabasebenzisi banokwandisa ukusebenza kunye nexesha elide lezixhobo zoomatshini kwiimeko ezahlukeneyo zokusebenza.
