Kodi ubwino wosankha granite ngati bedi la makina ndi wotani?

Choyamba, makhalidwe abwino kwambiri a thupi

Granite ndi chinthu cholimba kwambiri, kuuma kwake kumakhala kokwera, nthawi zambiri kumakhala pakati pa milingo isanu ndi umodzi ndi isanu ndi iwiri, ndipo mitundu ina imatha kufika pa milingo 7-8, zomwe zimakhala zapamwamba kuposa zipangizo zomangira monga marble, njerwa, ndi zina zotero. Nthawi yomweyo, kuchuluka kwa granite kumakhala kwakukulu, nthawi zambiri kumakhala pakati pa 2.5 ndi 3.1 magalamu pa sentimita imodzi (kapena matani 2.8-3.1 pa mita imodzi), mphamvu yopondereza ndi yayikulu kwambiri, imatha kufika 150-300Mpa, yokhala ndi mphamvu yabwino yonyamula katundu komanso yogwedezeka. Makhalidwe amenewa amachititsa granite kugwiritsa ntchito bedi lamakina kupirira katundu ndi kupanikizika kwakukulu, osati kosavuta kusintha ndi kuwonongeka.

Chachiwiri, makhalidwe okhazikika a mankhwala

Granite ili ndi mphamvu yabwino kwambiri yolimbana ndi dzimbiri la asidi ndi alkali ndipo siivuta kuiwononga ndi kuiwononga ndi mankhwala. Izi zikutanthauza kuti pokonza makina, ngakhale itakumana ndi choziziritsira kapena mafuta odzola, bedi la granite likhoza kukhala lolimba, ndipo silidzakhudza kulondola kwake ndi nthawi yake yogwirira ntchito chifukwa cha dzimbiri lalifupi.Ngakhale granite ili ndi mphamvu yabwino yolimbana ndi dzimbiri la asidi ndi alkali, imasamalidwa bwino ikakonzedwa, komanso imakonzedwa bwino pamalopo nthawi yake kuti ipewe madzi owononga omwe amasungidwa pamwamba kwa nthawi yayitali kuti awononge kulondola kwa pamwamba pake.

Chachitatu, kuchuluka kwa kutentha komwe kumawonjezeka ndi kochepa

Chiŵerengero cha kutentha cha granite ndi chochepa, chomwe chingalepheretse kusintha kwa kutentha. Pakukonza makina, chifukwa cha kupanga kutentha kodula ndi kutentha kwa kukangana, kutentha kwa chida cha makina kudzasintha. Ngati chiŵerengero cha kutentha cha bedi ndi chachikulu, chidzapangitsa kuti bedi lisinthe, motero kukhudza kulondola kwa makina. Bedi la granite ndi losiyana ndi bedi lachitsulo choponyedwa, ndipo silidzakhudzidwa ndi kutentha, zomwe zingathandize kuchepetsa kusinthaku ndikuwonetsetsa kuti kukonza kuli kolondola.

Chachinayi, kukana bwino kugwedezeka

Chifukwa cha kuchuluka kwake kwakukulu komanso magwiridwe antchito abwino kwambiri oletsa kugwedezeka, bedi loyambira la granite lingathe kuchepetsa bwino kusokonezeka kwa kugwedezeka kwa njira yopangira makina. Khalidweli ndilofunika kwambiri pakudula mwachangu kapena kukonza molondola, zomwe zingathandize kukonza makina ndikuwonjezera moyo wa chipangizocho.

5. Kukonza bwino kwambiri

Granite ndi chinthu chachilengedwe chokhala ndi kapangidwe ndi mtundu wofanana, chomwe chingasinthidwe m'mawonekedwe ndi kukula kosiyanasiyana malinga ndi zosowa zenizeni. Kudzera mu kudula, kupala, kupukuta, kuboola, kuponya ndi njira zina zokonzera, granite imatha kusinthidwa kukhala bedi lamakina lolondola kwambiri komanso lapamwamba kuti ikwaniritse zofunikira pakulondola kwamakono komanso kukhazikika kwa makina.

6. Mtengo wotsika wokonza

Bedi la granite silimavalidwa mosavuta komanso silimawonongeka mukamagwiritsa ntchito, kotero ndalama zolikonzera zimakhala zochepa. Kuyeretsa ndi kuyang'anitsitsa nthawi zonse ndiko komwe kungathandize kuti ligwire bwino ntchito.

Mwachidule, kusankha granite ngati bedi la makina kuli ndi zabwino zambiri, kuphatikizapo makhalidwe abwino kwambiri, makhalidwe okhazikika a mankhwala, kuchuluka kochepa kwa kutentha, kukana kugwedezeka bwino, kulondola kwambiri pakukonza zinthu komanso ndalama zochepa zosamalira. Ubwino uwu umapangitsa bedi la granite m'munda wa makina kukhala ndi mwayi wosiyanasiyana wogwiritsira ntchito.
