Ukuphakama Kwezinto Eziphathekayo: Kutheni I-Granite Iphumelela Kakhulu Kwintsimbi Kwi-Precision Gauging
Ukukhethwa kwegranite njengesixhobo sokulinganisa okuchanekileyo kuvela kwiimpawu ezibonakalayo ezingenakulinganiswa ne-ceramics yobunjineli kunye nentsimbi eqinileyo kwizicelo ezibalulekileyo. Uzinzo lobushushu luqala phakathi kwezi nzuzo. Igranite ibonisa i-coefficient yokwandiswa kobushushu ukusuka kwi-3 ukuya kwi-8 × 10⁻⁶ nge-degree Celsius, xa kuthelekiswa nentsimbi emalunga ne-11 × 10⁻⁶ nge-degree Celsius. Kwiindawo apho ubushushu butshintsha-tshintsha—nakwiilebhu ezilawulwayo—le mahluko ahlangana kuyo yonke imijikelo yokulinganisa. I-steel gauge ejongene nobushushu obuyi-5°C ngexesha lotshintsho lokutshintsha ivelisa impazamo enkulu kune-granite counterpart phantsi kweemeko ezifanayo.
Ukuqina kunika enye inzuzo ebalulekileyo. Njengoko ubunzima be-Shore budlula i-70 kunye nobunzima be-Mohs obuyi-6 ukuya kwi-7, i-granite iyamelana nokuguguleka ngeendlela ezigcina ukuchaneka kangangeminyaka emininzi endaweni yeminyaka. Amanqanaba okuguguleka okulinganisiweyo kwii-granite gauges ahlala engaphantsi kwe-1 micrometer ngemitha ngexesha lokusebenza kwazo, ngelixa ii-geages zentsimbi zifuna ukuqinisekiswa kwakhona rhoqo kwaye ekugqibeleni ziphinde zigaywe ukuze kugcinwe ukuchaneka okufanayo.
Mhlawumbi ingacacanga kangako kodwa ibaluleke ngokulinganayo, igranite ayinayo intsalela yoxinzelelo lwangaphakathi. Yenziwe ngexesha le-geological, igranite ifikelela kwimeko yokulingana kwangaphakathi engenakufikelelwa zizinto ezenziwe ngumntu. Intsimbi, nokuba inyangwa ngobushushu, ithwala uxinzelelo lwangaphakathi oluphumla kancinci kancinci ngokuhamba kwexesha, nto leyo ebangela utshintsho oluncinci olunokuthi lungabonakali phakathi kwamaxesha okulinganisa. Xa ufuna ukuzithemba kokulinganisa okuqhubeka kwiminyaka emininzi yenkonzo, lo mahluko wozinzo uba mkhulu.
