Waa maxay hababka ku lug leh soo saarista granite toosan iyo waa maxay saxsanaanta ugu sareysa ee la gaari karo?

I. Habka wax soo saarka ee Toosan Granit
Baaritaanka alaabta ceeriin iyo goynta
Shuruudaha xulashada walxaha: Granite-tayo sare leh cufnaanta ≥2.7g/cm³ iyo heerka nuugista biyaha ee <0.1% (sida "Jinan Green" ee Shandong iyo "Black Gold Sand" ee Hindiya) waa in la doortaa. Qaybaha macdanta ah waa in ay noqdaan kuwo lebbisan (quartz particles ≤2mm), oo aan lahayn dildilaac iyo dalool, dhagxaanta cilladda qarsoonna waa in laga saaraa iyadoo la ogaanayo cilladda raajada.
Goynta qallafsan: Isticmaal miinshaar wareeg ah oo dheeman ah si aad u gooyso bannaan bannaan oo 5-10mm ka weyn cabbirka alaabta la dhammeeyey. Khaladka fidsan ee dusha goynta waa in lagu xakameeyaa ± 0.5mm gudahood.
2. Daaweynta gabowga
Gabowga dabiiciga ah: Geli jidhka cagaarka ah hawada furan 6 ilaa 12 bilood. Iyada oo loo marayo kala duwanaanshaha heerkulka u dhexeeya habeen iyo maalin iyo isbeddelka qoyaanka, in ka badan 90% diiqada gudaha ayaa la sii daayaa si looga hortago qallafsanaanta marxaladda dambe.
Gabowga macmal ah (ikhtiyaar): Warshadaha qaarkood waxay isticmaalaan foornada heerkulka joogtada ah (100-150 ℃) 24 saacadood si ay u dardargeliyaan sii deynta walaaca, taas oo ku habboon amarrada degdegga ah, laakiin saameyntu wax yar ayay ka yar tahay tan gabowga dabiiciga ah.
3. Shiidi qallafsan iyo farsamaynta dusha tixraaca
Shiididda qallafsan iyo qaabaynta: Isticmaal giraangiraha dheemanka mesh 200-400 si aad u shiiddo meesha bannaan, ka saar xadhkaha goynta, saxdo fidsanaanta ± 0.5mm ilaa ± 0.1mm/m (100μm/m), oo go'aami dusha tixraaca.
Daawaynta dusha sare ee aan shaqaynayn: Shamfer ama jaakad dhinaca iyo dusha hoose (sida ku buufinta rinjiga lidka ku ah miridhku) si looga hortago dildilaaca geesaha iyo balaadhinta nuugista qoyaanka.

4. Shiididda saxda ah (habka ubucda)
boodboodka saxda ah waxaa lagu gaaraa shiidid heersare ah, kaas oo loo qaybiyay saddex marxaladood:

Shiidi qallafsan: Isticmaal 400-800 mesh abrasives (silikon carbide ama dheeman micro-budo) oo lagu daro madal wax shiididda granite si loo saxo fidsanaanta ilaa ±10μm/m, iyo qallafsanaanta dusha sare Ra≤0.8μm.
Xakamaynta saxda ah: Adigoo u beddelaya 1200-2000 mesh abrasives iyo isku-darka heerka elektiroonigga ah (sax ahaan ± 1μm / m) ee kormeerka waqtiga-dhabta ah, fidsanaanta ayaa loo hagaajiyay ± 3μm / m, iyo qallafsanaanta dusha Ra waa ≤0.4μm.
Shiidi Ultra-fine (furaha alaabta-sax sare): By isticmaalaya W10-W5 fasalka micro-budada (xajmiga qayb 5-10μm) iyo dareere polishing kiimikada, iyada oo loo marayo fal dual ah "shiidida farsamada + daxalka kiimikada", flatness final gaari kartaa ± 1μm / m, iyo roughness dusha Ra≤0.2μm.
5. Xaqiijinta iyo sixitaanka saxda ah
Qalabka lagu ogaanayo: interferometer laser ah (sax ± 0.1μm) iyo heerka elektarooniga ah (xarka 0.001mm/m) ayaa loo isticmaalaa in lagu sameeyo ogaanshaha guud ee fidsanaanta iyo toosnaanta, iyo in lagu sawiro khariidad qaybinta qaladka.
Sixitaan xiran: Iyada oo ku saleysan xogta ogaanshaha, shiidida dheeriga ah ee maxalliga ah ayaa lagu fuliyaa aagga qaladka sareeyo iyada oo loo sii marayo mashiinka wax shiida ee CNC ilaa qaladka cabbirka buuxa laga xakameynayo xadka bartilmaameedka.
6. Ilaalinta dusha sare iyo baakadaha
Daawaynta ilaalinta: Ku buufi daahan silica-cabbir ah (5-10μm qaro weyn) dusha tixraaca, oo mari lakabka ka hortagga daxalka ee dusha aan shaqaynayn si looga hortago nuugista qoyaanka ama oksaydhka inta lagu jiro isticmaalka muddada dheer.
Baakadaha saxda ah: Waxay ku jirtaa kiisas alwaax ah oo aan naxdin lahayn oo leh qallajiyeyaasha. Inta lagu jiro gaadiidka, kala duwanaanshaha heerkulka waxaa lagu xakameynayaa gudaha ± 5 ℃ si looga fogaado hoos u dhigista saxda ah ee uu keeno gariirka.
Ii. Heerarka Saxda ah ee ugu Sareeya iyo Heerka Warshadaha
Saxnaanta toosan granite waxay ku salaysan tahay qaladka flatness sida index core. Marka loo eego halbeegga qaranka (GB/T 4977-2018) iyo heerka caalamiga ah (ISO 2768-2), buundooyinkeeda saxsanaanta iyo cabbirrada u dhigma waa sida soo socota:

Shaybaarada sare waxay gaari karaan saxnaanta ugu dambeysa:
Iyada oo loo marayo farsamooyinka nano-cabbirka (sida polishing magneorheological iyo ion beam modification), flatness ee qaar ka mid ah alaabta-dhamaadka sare waa la jejebin karaa ilaa ± 0.5μm/m (ie, qaladka halkii mitir dhererka aan ka badnayn 0.5 micrometers), soo dhawaaday ee tixraaca heerka-optical. Inta badan waxaa loo adeegsadaa xaalado aad u sax ah sida hawada hawada iyo machadyada metrology.

Iii. Isbarbardhigga Qodobbada Saamaynaya Saxnaanta

Soo koobid: Saxnaanta sare ee toosan granite waxay ku tiirsan tahay nidaamka buuxa ee kantaroolka "qalabka cayriin ee tayada sare leh + gabowga aadka u dheer + shiididda darajada leh + jawi adag", oo ay ka mid tahay geeddi-socodka shiidadu waa udub dhexaadka horumarka saxda ah. Iyadoo horumarinta tignoolajiyada nanofabrication, saxnimadeedu waxay si tartiib tartiib ah ugu sii socotaa heerka hoose ee micron-ka waxayna noqotay qalab aan la bedeli karin oo ku yaala goobta wax soo saarka sare.
