Amaqonga okuchaneka kwegranite aziwa kakhulu kushishino lokuvelisa oluchaneke kakhulu ngenxa yokuzinza kwawo okumangalisayo, ukuqina, kunye nokumelana nokungcangcazela. Nangona kunjalo, umbuzo omnye uhlala uphakama phakathi kweenjineli kunye neengcali zolawulo lomgangatho: ngaba la maqonga ayanda okanye ancipha ngenxa yotshintsho lobushushu, kwaye oku kuchaphazela njani ukuchaneka kokulinganisa?
I-Granite, njengelitye lendalo, ibonisa ukwanda kobushushu, kodwa i-coefficient yayo yokwanda kobushushu iphantsi kakhulu xa ithelekiswa neentsimbi ezifana nentsimbi okanye i-aluminium. I-granite emnyama esemgangathweni ophezulu, njenge-ZHHIMG® Black Granite esetyenziswa kumaqonga ethu, idla ngokwanda kuphela malunga ne-4–5 × 10⁻⁶ nge-degree Celsius. Oku kuthetha ukuba kwiintlobo ezininzi zezicelo zoshishino, utshintsho olubangelwa bubushushu luncinci, kwaye iqonga ligcina uzinzo oluphezulu phantsi kweemeko eziqhelekileyo zeworkshop.
Nangona ubushushu bayo buphantsi, ukuguquguquka kobushushu kusenokuchaphazela ukuchaneka kokulinganisa xa kufuneka ukuchaneka okukhulu. Umzekelo, kwiindawo ezicocekileyo okanye kwiindawo zokuseta izixhobo ezichanekileyo kakhulu, notshintsho oluncinci lobushushu lunokutshintsha indawo yezixhobo, olunokuchaphazela ukulinganiswa kwamanqanaba e-micrometer. Ukunciphisa oku, iilabhoratri ezichanekileyo zihlala zilawula amaqondo obushushu angaphakathi ngaphakathi kweendawo ezixineneyo kwaye zivumele amaqonga e-granite ukuba aqhelelane ngaphambi kokulinganisa okubalulekileyo.
Enyanisweni, ukudityaniswa kozinzo lwezinto zegranite kunye nolawulo olufanelekileyo lokusingqongileyo kuqinisekisa ukuba ukwanda kobushushu kunempembelelo encinci ekuchanekeni kweqonga ngokubanzi. Iinjineli ziyazuza koku kuthembakala, njengoko amaqonga egranite ebonelela ngomphezulu ohambelanayo wereferensi ye-metrology, i-assembly, kunye nemisebenzi yokuhlolwa. Ukuzinza kwegranite phezu kweentsimbi kugxininisa isizathu sokuba ihlala ilukhetho olukhethwayo kumashishini afuna ukuchaneka kwexesha elide, kubandakanya i-aerospace, ukwenziwa kwezixhobo zonyango, kunye ne-elektroniki eziphambili.
Kwi-ZHHIMG, amaqonga ethu okuchaneka kwegranite ayilwe ngononophelo ukuze aphucule uzinzo lobushushu, ukuqinisekisa ukuba imilinganiselo yakho ihlala ihambelana kwaye ithembekile. Ukuqonda iimpawu zobushushu ezifihlakeleyo zegranite kunceda abasebenzisi ukuba benze izigqibo ezinolwazi xa beseka iinkqubo zokulinganisa kwaye kuqaqambisa iingenelo zegranite kunezinye izixhobo.
Kwabo bafuna umphezulu othembekileyo nochanekileyo onciphisa impembelelo yokutshintsha kwamaqondo obushushu, amaqonga egranite ayaqhubeka nokubeka umgangatho kushishino.
