Njengesixhobo esibalulekileyo sokubhekisa kwiindawo zokulinganisa ngokuchanekileyo, ukumelana nokuguguleka kwee-granite slabs kumisela ngokuthe ngqo ubomi bazo benkonzo, ukuchaneka kokulinganisa, kunye nokuzinza kwexesha elide. Oku kulandelayo kuchaza ngokucwangcisiweyo amanqaku aphambili okumelana nokuguguleka kwawo ngokwembono yeempawu zezinto ezibonakalayo, iindlela zokuguguleka, iingenelo zokusebenza, izinto ezinefuthe, kunye namaqhinga okugcina.
1. Iimpawu zezinto kunye neziseko zokuxhathisa ukunxitywa
Ukuqina Okulungileyo kunye nolwakhiwo oluxineneyo
Iislabhu zegranite zenziwe ikakhulu yi-pyroxene, i-plagioclase, kunye nenani elincinci le-biotite. Ngokukhula kwendalo ixesha elide, ziphuhlisa isakhiwo esincinci, zifikelela kubunzima be-Mohs obuyi-6-7, ubunzima be-Shore obudlula i-HS70, kunye namandla okucinezela angama-2290-3750 kg/cm².
Olu lwakhiwo luxineneyo (ukufunxwa kwamanzi <0.25%) luqinisekisa ukubophana okuqinileyo phakathi kweenkozo, nto leyo ebangela ukuba ukukrwela komphezulu kube ngcono kakhulu kunesinyithi esityhidiweyo (esinobunzima obuyi-HRC 30-40 kuphela).
Ukwaluphala Ngokwendalo kunye nokukhululwa koxinzelelo lwangaphakathi
Iislabhu zegranite zivela kwiindlela ezisemgangathweni zamatye angaphantsi komhlaba. Emva kweminyaka eyizigidi yokwaluphala kwendalo, zonke iingcinezelo zangaphakathi ziye zakhululwa, nto leyo ebangela iikristale ezintle nezixineneyo kunye nobume obufanayo. Olu zinzo lwenza ukuba ingachaphazeleki lula zii-microcracks okanye i-deformation ngenxa yokuguquguquka koxinzelelo ngexesha lokusetyenziswa ixesha elide, ngaloo ndlela igcina ukumelana kwayo nokuguguleka ngokuhamba kwexesha.
II. Iindlela zokunxiba kunye nokusebenza
Iifom zokunxiba eziphambili
Ukuguguleka okurhabaxa: Ukunqunyulwa okuncinci okubangelwa ziinxalenye eziqinileyo ezityibilikayo okanye eziqengqelekayo phezu komphezulu. Ubunzima obukhulu begranite (obulingana ne-HRC > 51) buyenza imelane ngokuphindwe kabini ukuya kathathu neenxalenye ezirhabaxa kunentsimbi ephosiweyo, nto leyo enciphisa kakhulu ubunzulu bokukrweleka komphezulu.
Ukuguguleka okunamathelayo: Ukudluliselwa kwezinto kwenzeka phakathi kwemiphezulu yoqhagamshelwano phantsi koxinzelelo oluphezulu. Iipropati zeGranite ezingezizo ezesinyithi (ukuguquguquka okungenamagnethi kunye nokungaguquguquki kweplastiki) zithintela ukunamathelana kwesinyithi nesinyithi, nto leyo ebangela ukuba izinga lokuguguleka lisondele kwi-zero.
Ukudinwa: Ukuxobuka komphezulu okubangelwa kuxinzelelo olujikelezayo. I-Granite's high elastic modulus (1.3-1.5×10⁶kg/cm²) kunye nokufunxwa kwamanzi kancinci (<0.13%) zibonelela ngokumelana nokudinwa okugqwesileyo, okuvumela umphezulu ukuba ugcine ukukhanya okufana nesipili nokuba sele usetyenziswe ixesha elide.
Idatha yoKusebenza eqhelekileyo
Uvavanyo lubonisa ukuba ii-granite slabs zifumana kuphela i-1/5-1/3 yokuguguleka kwee-cast iron slabs phantsi kweemeko ezifanayo zokusebenza.
Ixabiso le-Ra yoburhabaxa bomphezulu lihlala lizinzile ngaphakathi koluhlu lwe-0.05-0.1μm kwixesha elide, lihlangabezana neemfuno zokuchaneka kweKlasi 000 (ukunyamezelana kokuthe tyaba ≤ 1×(1+d/1000)μm, apho u-d bubude obuthe tyaba).
III. Iingenelo Eziphambili Zokumelana Nokunxitywa
I-Coefficient ephantsi yokuHlanganisa kunye nokuzithambisa
Umphezulu ogudileyo wegranite, onomlinganiselo wokungqubana we-0.1-0.15 kuphela, unika ukumelana okuncinci xa kulinganiswa izixhobo zityibilika kuwo, nto leyo enciphisa amazinga okuguguleka.
Indalo yokuba iGranite ayinaoyile isusa ukuguguleka okubangelwa luthuli olufunxwa yi-lubricant, nto leyo ebangela ukuba iindleko zokulungisa zibe ziphantsi kakhulu kunee-cast iron slabs (ezifuna ukusetyenziswa rhoqo kwe-anti-rust oil).
Ayimelani nokugqwala kweekhemikhali kunye nomhlwa
Ukusebenza kakuhle kakhulu (akukho corrosion ngaphakathi koluhlu lwe-pH oluyi-0-14), ifanelekile ukusetyenziswa kwiindawo ezifumileyo nezineekhemikhali.
Iimpawu ezimelana nomhlwa ziyasusa ukurhawuzelela komphezulu okubangelwa kukugqwala kwesinyithi, nto leyo ebangela ukuba izinga lokutshintsha kokuthamba libe <0.005mm/ngonyaka emva kokusetyenziswa ixesha elide.
IV. Izinto Eziphambili Ezichaphazela Ukumelana Nokunxitywa
Ubushushu obuphakathi kunye nokufuma
Ukutshintshatshintsha kobushushu (>±5°C) kunokubangela ukwanda nokuncipha kobushushu, okubangela ukuqhekeka okuncinci. Indawo yokusebenza ecetyiswayo bubushushu obulawulwayo obuyi-20±2°C kunye nokufuma okungu-40-60%.
Ukufuma okuphezulu (>70%) kukhawulezisa ukungena komswakama. Nangona i-granite inesantya esiphantsi sokufunxa amanzi, ukuchatshazelwa kumswakama ixesha elide kusenokunciphisa ubulukhuni bomphezulu.
Uxinzelelo lomthwalo kunye noQhagamshelwano
Ukugqithisa umthwalo olinganiselweyo (ngesiqhelo i-1/10 yamandla oxinzelelo) kunokubangela ukutyumza okuqhelekileyo. Umzekelo, imodeli ethile ye-granite slab inomthwalo olinganiselweyo we-500kg/cm². Xa isetyenziswa ngokwenene, imithwalo yempembelelo yexeshana edlula eli xabiso kufuneka ithintelwe.
Ukusasazwa koxinzelelo lokunxibelelana okungalinganiyo kukhawulezisa ukuguguleka. Inkxaso enamachaphaza amathathu okanye uyilo lomthwalo olusasazwa ngokulinganayo luyacetyiswa.
Ukugcinwa kunye nokucoca
Musa ukusebenzisa iibhrashi zesinyithi okanye izixhobo eziqinileyo xa ucoca. Sebenzisa ilaphu elingenathuli elimanziswe nge-isopropyl alcohol ukuze ungakrweli umphezulu.
Jonga rhoqo uburhabaxa bomphezulu. Ukuba ixabiso leRa lidlula i-0.2μm, kufuneka ucofe kwakhona kwaye ulungise.
V. Amaqhinga oLondolozo noPhuculo lokuxhathisa ukuNgcola
Ukusetyenziswa Nokugcinwa Ngendlela Efanelekileyo
Ziphephe iimpembelelo ezinzima okanye ukuhla. Amandla empembelelo adlula i-10J anokubangela ukulahleka kweenkozo.
Sebenzisa isiseko ngexesha lokugcina kwaye ugqume umphezulu ngefilimu engangeni uthuli ukuthintela uthuli ukuba lungangeni kwii-micropores.
Yenza uhlengahlengiso oluchanekileyo rhoqo
Jonga ukuba i-flat ingakanani nge-elektroniki rhoqo emva kweenyanga ezintandathu. Ukuba impazamo idlula umlinganiselo wokunyamezela (umz., impazamo evumelekileyo yepleyiti ye-00-grade yi-≤2×(1+d/1000)μm), yibuyisele efektri ukuze ilungiswe kakuhle.
Faka iwax yokukhusela ngaphambi kokuba uyigcine ixesha elide ukuze unciphise ukugqwala kwendalo.
Iindlela Zokulungisa Nokwenza Kabutsha
Ukuguguleka komphezulu <0.1mm kunokulungiswa apha ekhaya nge-diamond abrasive paste ukubuyisela isipili esingaphezulu kweRa ≤0.1μm.
Ukuguguleka okunzulu (>0.3mm) kufuna ukubuyiselwa efektri ukuze kugaywe kwakhona, kodwa oku kuya kunciphisa ubukhulu bepleyiti iyonke (umgama wokugaywa omnye ≤0.5mm).
Ukumelana nokuguguleka kwee-granite slabs kuvela kwintsebenziswano phakathi kweempawu zazo zendalo zezimbiwa kunye nomatshini wokuchwetheza ngokuchanekileyo. Ngokuphucula imeko yokusetyenziswa, ukwenza inkqubo yolondolozo ibe semgangathweni kunye nokusebenzisa iteknoloji yokulungisa, inokuqhubeka nokubonisa iingenelo zayo zokuchaneka okuhle kunye nobomi obude kwindawo yokulinganisa ngokuchanekileyo, ibe sisixhobo sokulinganisa kwimveliso yemizi-mveliso.
