Yintoni umahluko phakathi kwe-coefficient of thermal expansion phakathi kwe-cast iron bed kunye ne-mineral cast bed? Lo mahluko uchaphazela njani ukuchaneka komatshini kwiindawo ezahlukeneyo zobushushu?

 

Iibhedi zokuphosa iGranite vs. Cast Iron kunye neMineral: Ukuqonda iiCoefficients zokwandisa ubushushu kunye nempembelelo yazo ekuchanekeni kwezixhobo zomatshini

Xa kufikwa ekwakhiweni kweebhedi zezixhobo zoomatshini, izinto ezifana negranite, isinyithi esityhidiweyo, kunye ne-mineral casting zisetyenziswa kakhulu ngenxa yeempawu zazo ezikhethekileyo. Into ebalulekileyo ekufuneka iqwalaselwe ekukhetheni ezi zixhobo yi-thermal expansion coefficient yazo, ingakumbi kwiindawo ezinamaqondo obushushu ahlukeneyo. Umahluko kwii-thermal expansion coefficients phakathi kweebhedi zesinyithi esityhidiweyo kunye nee-mineral casting unokuchaphazela kakhulu ukugcinwa ngokuchanekileyo kwezixhobo zoomatshini kwiindawo ezahlukeneyo zobushushu.

Isinyithi esitshisiweyo, into eqhelekileyo esetyenziswa ekwakheni izixhobo zomatshini, inomlinganiselo ophezulu wokwandisa ubushushu. Oku kuthetha ukuba njengoko amaqondo obushushu etshintshatshintsha, iibhedi zesinyithi esitshisiweyo zinomlinganiselo ophezulu wokwanda nokuncipha, okunokukhokelela kutshintsho lobukhulu kwisixhobo somatshini. Kwelinye icala, isinyithi esitshisiweyo, esihlala sisenziwa ngezinto ezifana ne-epoxy resin kunye nee-granite aggregates, sinomlinganiselo ophantsi wokwandisa ubushushu xa kuthelekiswa nesinyithi esitshisiweyo. Olu phawu luvumela iibhedi ezitshisiweyo zesinyithi ukuba zibonise utshintsho oluncinci lobukhulu xa kuthelekiswa notshintsho lobushushu.

Impembelelo yale mahluko ibaluleka ngakumbi kwiindawo apho ulawulo lobushushu lunzima khona. Kwiindawo ezinobushushu obuphezulu, i-coefficient yokwandisa ubushushu ephezulu yesinyithi esityhidiweyo inokukhokelela ekungachaneki kobukhulu kwisixhobo somatshini, nto leyo echaphazela ukuchaneka kwaso kunye nokusebenza kwaso. Ngokwahlukileyo koko, iibhedi zokufaka izimbiwa, ezine-coefficient yazo yokwandisa ubushushu ephantsi, zixhotyiswe ngcono ukugcina ukuchaneka kwiimeko ezinjalo.

Ngokwahlukileyo koko, kwiindawo ezinobushushu obuphantsi, i-coefficient ephantsi yokwandiswa kobushushu bokuphoswa kwezimbiwa inokubangela isakhiwo esiqinileyo xa kuthelekiswa nesinyithi esityhidiweyo, nto leyo enokuchaphazela impendulo eguquguqukayo yesixhobo somatshini kunye neempawu zokudambisa ukungcangcazela. Ukuqonda olu mahluko kubalulekile kubavelisi kunye nabasebenzisi ukuba benze izigqibo ezinolwazi ngokusekelwe kwiimeko ezithile zobushushu apho isixhobo somatshini siza kusebenza khona.

Ukuqukumbela, i-thermal expansion coefficient idlala indima ebalulekileyo ekukhetheni izixhobo zeebhedi zezixhobo zomatshini. Nangona i-cast iron ibisoloko iyindlela eqhelekileyo yokukhetha, i-thermal expansion coefficient ephantsi ye-mineral casting, edla ngokubandakanya i-granite, inika iingenelo zokugcina ukuchaneka kwiindawo ezahlukeneyo zobushushu. Ngokuqwalasela ezi zinto, abavelisi kunye nabasebenzisi banokuphucula ukusebenza kunye nobude bexesha lezixhobo zomatshini kwiimeko ezahlukeneyo zokusebenza.
