Igranite lilitye lendalo elisetyenziswa kakhulu ekwenzeni iinxalenye zoomatshini kwimizi-mveliso yeemoto kunye ne-aerospace.Nangona le nto ithathwa njengento ehlala ixesha elide kwaye inokuthenjwa, isenokuthi ibe neziphene ezinokuchaphazela umgangatho kunye nokusebenza kwayo.Kweli nqaku, siza kuxubusha ezinye iziphene eziqhelekileyo ezinokuthi zenzeke kwiindawo zomatshini wegranite.
1. Ukungafezeki komphezulu
Esinye seziphene eziphawulekayo kumatshini wegranite kukungafezeki komphezulu.Oku kungafezeki kunokusuka kwimikrwelo emincinci kunye neziphako ukuya kwimiba enzulu efana nokuqhekeka kunye neetshiphusi.Ukungafezeki komphezulu kunokwenzeka ngexesha lenkqubo yokwenziwa okanye ngenxa yoxinzelelo lwe-thermal, olunokubangela ukuba i-granite idibanise okanye iguqulwe.Ezi ziphene zinokuphazamisa ukuchaneka kunye nokuchaneka kwenxalenye yomatshini, echaphazela ukusebenza kwayo.
2. I-Porosity
I-Granite yimpahla ene-porous, oku kuthetha ukuba inezikhewu ezincinci okanye imingxuma enokuthi ibambe umswakama kunye nolunye ulwelo.I-Porosity sisiphene esiqhelekileyo esinokuthi senzeke kwiindawo zomatshini we-granite, ngakumbi ukuba izinto eziphathekayo zingavalwanga ngokufanelekileyo okanye zikhuselwe.I-granite enebhobhobhothi inokufunxa ulwelo olufana ne-oyile, into yokupholisa, kunye namafutha, nto leyo enokubangela umhlwa kunye nezinye iindlela zomonakalo.Oku kunokukhokelela ekunxibeni kwangaphambili kunye nokukrazula inxalenye yomatshini, ukunciphisa ixesha lokuphila kwayo.
3. Ukubandakanywa
I-inclusions ngamasuntswana angaphandle anokuthi abanjwe ngaphakathi kwezinto zegranite ngexesha lenkqubo yokwenziwa.La maqhekeza anokuba avela emoyeni, izixhobo zokusika, okanye i-coolant esetyenziswa ngexesha lokwenziwa.Ukufakwa kunokubangela iindawo ezibuthathaka kwi-granite, okwenza kube lula ukukrazula okanye ukukrazula.Oku kunokuphazamisa amandla kunye nokuqina kwenxalenye yomatshini.
4. Ukwahluka koMbala
I-Granite ilitye lendalo, kwaye ngenxa yoko, ingaba nokuhluka kombala kunye nokuthungwa.Ngelixa olu tshintsho lubonwa ngokubanzi njengophawu lobuhle, ngamanye amaxesha lunokuba sisiphene ukuba luchaphazela ukusebenza kwenxalenye yomatshini.Ngokomzekelo, ukuba iinqununu ezimbini zegranite zisetyenziselwa inxalenye yomshini omnye, kodwa zinemibala eyahlukeneyo okanye iipateni, oku kunokuchaphazela ukuchaneka okanye ukuchaneka kwenxalenye.
5. Ubungakanani kunye nokwahluka kweMilo
Esinye isiphene esinokubakho kumatshini wegranite kukuhluka kobukhulu kunye nokumila.Oku kunokwenzeka ukuba i-granite ayinqunywanga ngokufanelekileyo okanye ukuba izixhobo zokusika azihambelani kakuhle.Nokuba ukuhluka okuncinci kobukhulu okanye imilo kunokuchaphazela ukusebenza kwenxalenye yomatshini, njengoko kunokubangela ukungahambi kakuhle okanye izikhewu ezinokuphazamisa ukusebenza kwayo.
Ukuqukumbela, ngelixa i-granite iyinto ehlala ixesha elide kwaye inokuthenjwa kumatshini kumashishini eemoto kunye ne-aerospace, isenokuthi ibe neziphene ezinokuchaphazela umgangatho kunye nokusebenza kwayo.Ezi ziphene ziquka ukungafezeki komphezulu, i-porosity, inclusions, ukuhluka kombala, kunye nobukhulu kunye nokuhluka kobume.Ngokuziqonda ezi ziphene kwaye bathathe amanyathelo okuzithintela, abavelisi banokuvelisa izixhobo zomatshini wegranite ezikumgangatho ophezulu ezihlangabezana neemfuno zala mashishini.
