Kodi ubwino wosankha granite ngati bedi lamakina ndi chiyani?

Choyamba, apamwamba thupi katundu

Granite ndi zinthu zovuta kwambiri, kuuma kwake ndi mkulu, nthawi zambiri pakati pa sikisi ndi zisanu ndi ziwiri milingo, ndipo mitundu ina akhoza kufika misinkhu 7-8, amene ali apamwamba kuposa zipangizo zonse zomangira monga nsangalabwi, njerwa, etc. Pa nthawi yomweyo, kachulukidwe wa lubwe ndi lalikulu, nthawi zambiri pakati pa 2.5 ndi 3.1 magalamu pa kiyubiki centimita (kapena 2.8-cubic mphamvu), compresses kwambiri akhoza kufika mamita 2.8-3 cubic mphamvu. 150-300Mpa, yokhala ndi katundu wabwino komanso zivomezi. Makhalidwe amenewa kupanga granite mu ntchito mawotchi bedi akhoza kupirira kwambiri katundu ndi mavuto, osati zosavuta mapindikidwe ndi kuwonongeka.

Chachiwiri, khola mankhwala katundu

Granite ili ndi asidi wabwino kwambiri komanso kusachita dzimbiri kwa alkali ndipo sikophweka kuti ikhale ndi dzimbiri ndi kukokoloka ndi mankhwala. Izi zikutanthauza kuti popanga makina, ngakhale atakumana ndi zoziziritsa kuzizira kapena mafuta, bedi la granite limatha kukhala lokhazikika, ndipo silingakhudze kulondola kwake komanso moyo wautumiki chifukwa cha dzimbiri lalifupi.Ngakhale kuti granite ili ndi asidi wabwino komanso kukana kwa dzimbiri zamchere, imasungidwa bwino pambuyo pokonza, chithandizo chanthawi yake chapamtunda kuti chipewe zakumwa zowononga zomwe zimasungidwa pamtunda kwa nthawi yayitali kuti ziwononge kulondola kwake.

Chachitatu, coefficient of thermal expansion ndi yaying'ono

Mphamvu yowonjezera kutentha kwa granite ndi yaying'ono, yomwe imatha kukana kusintha kwa kutentha. Mu makina opanga makina, chifukwa cha mbadwo wa kudula kutentha ndi kutentha kwamphamvu, kutentha kwa chida cha makina kudzasintha. Ngati coefficient of matenthedwe kukula kwa bedi lalikulu, izo zingachititse mapindikidwe bedi, motero zimakhudza Machining molondola. Bedi la granite ndi losiyana ndi bedi lachitsulo choponyedwa, ndipo silidzakhudzidwa ndi kutentha, zomwe zingathe kuchepetsa kusinthika kumeneku ndikuwonetsetsa kulondola kwa kukonza.

Chachinayi, kukana kugwedezeka kwabwino

Chifukwa cha voliyumu yake yayikulu komanso magwiridwe antchito abwino kwambiri oletsa kugwedezeka, bedi loyambira la granite limatha kuchepetsa kusokoneza kwa kugwedezeka pamakina. Khalidweli ndi lofunika kwambiri pakudula mwachangu kapena kukonza bwino, komwe kumatha kukulitsa luso la makina ndikukulitsa moyo wautumiki wa chida.

5. High processing mwatsatanetsatane

Granite ndi zinthu zachilengedwe zokhala ndi mawonekedwe ofanana ndi mtundu, zomwe zimatha kusinthidwa kukhala mawonekedwe ndi makulidwe osiyanasiyana malinga ndi zosowa zenizeni. Kupyolera mu kudula, planing, akupera, kubowola, kuponyera ndi zina zingapo processing, granite akhoza kukonzedwa kukhala apamwamba mwatsatanetsatane ndi apamwamba muyeso makina bedi kukwaniritsa zofunikira za makina olondola amakono ndi bata.

6. Mtengo wotsika wokonza

Bedi la granite silophweka kuvala ndi kupunduka panthawi yogwiritsira ntchito, choncho mtengo wokonza ndi wotsika kwambiri. Kuyeretsa ndi kuyang'anitsitsa nthawi zonse kungathandize kuti ntchitoyi ikhale yabwino.

Mwachidule, kusankha kwa granite ngati bedi lamakina kuli ndi zabwino zambiri, kuphatikiza zinthu zapamwamba zakuthupi, zinthu zokhazikika zamakemikolo, kuchuluka kwamafuta pang'ono, kukana kugwedezeka kwabwino, kulondola kwapamwamba komanso kutsika mtengo. Ubwino uwu umapangitsa bedi la granite pantchito yopanga makina kukhala ndi chiyembekezo chogwiritsa ntchito.
